Today, Sheet Metal Machines are being widely used to perform cut, drill, press and shear on various hardened materials including aluminium, brass, copper, steel, tin, nickel, etc. These operations help reform the shape and size of the materials. Uses of sheet metal machinery range from making panels for packaging to making parts for machines. These machine tools have also helped make various medical equipment and various mechanical tools. But the sheet metal machine we know today has gone through huge changes since its invention. In this article, we will see how the sheet metal machines evolved and became what we know it as today.
Introduction of the punching machine
Humans have been engaged in sheet metal works from centuries now. In the prehistoric times, need for making sophisticated tools, vessels and pieces of jewellery was one of the reasons which triggered the invention of sheet metal machines. Punching Machine is considered as one of the very first sheets metal machine. It is still used as a manual tool in small-scale industries to punch holes in metal sheets. Punch machine was used to drill holes in metal sheets using manual force.
Folding/Bending of metal sheets
When just punching hole was not enough for making a complex tool, bending of metal sheet was introduced. In the beginning, sheets were placed between a set of rolling cylinders. These cylinders clamp on sheets and form the bend. If the desired bend is not obtained, the sheets are passed through the cylinders again. This process continues until the desired bend is obtained. Modern technologies have made this machine to evolve into Magnetic Bending Machine in which electromagnets are used to form the bending.
Since the tool to be made from metal sheets varied, it was not possible to work with just folding and punching. As the use of metal products increased, there was a need for the introduction of a process that would allow cutting of large metal sheets. This was made possible only after the introduction of pivoted scissors. This enhanced the production process. Shearing Machines are still being used widely in today’s industry. These modern machines tools are made from high carbon and chrome steel blades which provide higher stability while performing the operations.
Modern machines tools
Sheet metal machines have evolved far from its predecessors. Introduction of steam power was the first turning point for these machines. Use of steam power replaced manual handling of tools and provided far better performance with a high rate of production. Next leap was the introduction of electric control machinery such as Electric Operated Slip Roll. The electric control not only eased the usage but also helps increase the productivity of the system. At small scale production plants, hand and foot operated machinery are still used but demand for a higher rate of production is forcing the replacement of traditional machines with modern machines.
Air cons (AC) are widely used in residential, commercial and industrial systems to actively pump out heat and maintain a predetermined temperature and humidity. They create an artificial environment which suitable for machines, human and agricultural produce.
Air conditioning systems fabrication
Most modern house and industrial buildings comprise of many rooms that need HVAC (heating, ventilation, air conditioning system). Instead of using a separate split AC for each room, all the rooms are fitted with ducts and vents and one system is used to control multiple rooms. HVAC system regulates temperature and humidity and creates a fresh environment.
This ducted system is made up of numerous square or round pipes made from light aluminum of stainless steel sheets. They span the entire house and connect to a central duct that aerates the room.
Role of bending machines in fabrication of these systems
To manufacture these pipes and ducts, sheet bending machines are used to fold light and heavy gauge sheets. These machines are therefore found in contractor’s fabrication labs where folding sheets constitute 60% of all fabrication process.
The sheet material is cut at the required position and then fastened on the equipment. This device then folds the sheet to the required angle (normally 450 to 900 for most AC applications).
To perform a series of perpendicular and angular folds on the same work piece, these devices utilize a back gauge and specially formed dies. The back gauge accurately positions the metal sheet so that the bend is put at the precise location. This allows precision and accurate fabrication of multiple folds on the same work piece.
To fabricate folds fast and effectively, this equipment must allow continuous and precision folding of these tubes. Light and medium sized bending machine are applied in the operations since the ducts must be light in weight but durable.
Modern CNC types are becoming common. These allow accurate and precision feed, easy clamping, bend monitoring, folding as well as automatic calculation of the back gauge position based on the angle of bending. They have high ramming speed and are suitable for high throughput industry.
For small jobs on residential and commercial areas, smaller devices with less tonnage are used. These are versatile and flexible and allow folding of smaller work pieces to different angles and shapes.
Bright market for this machine in this industry
The AC market is on the rise in most parts of the world due to emerging cities and need to have a controlled internal environment.
With the rapid rise in middle income earners and high growth rate in the construction of commercial and residential houses, machine tools used in fabrication and installation of these equipment will increase.
In 2012, the global AC market was valued at US$86.8 billion and US$91.6 billion in 2013. The Asia pacific region has the highest demand due to rising industrial, commercial and residential sectors. The main units demanded are roof tops, indoor packaged, chiller plants and central ducted types.
Iron and steel are the most common fabrication material in manufacturing and repair shops. They are widely used in construction, assembly, vehicle manufacture, processing and packaging industry. Large metal plates are produced in form of foils, rolls and plates that are then used for numerous applications. Bending is a common operation done in production centers. The component is plastically deformed along a given axis and this result to a change in geometry and shape. Various sheet metal bending equipments have been developed and are used during production. Essentially, this equipment folds the object into various angles and also produces various shapes during manufacturing. In this process, the material is first feed into the device. Manual or automatic controlled clamping that positions the components on the equipment is done. Then, the front plate of is then lifted to bend the plate to the required angle. Other forming methods can be accomplished using this instrument.
Use of the device in iron sheet manufacturing
Iron comes in various sizes and shapes depending on its utilization. During their production, the folding machine is utilized to produce various shapes and structures. Edge folding is the most common bending process performed using manual and automatic devices. The component is bent at the edges to various angles. The materials are first feed to the device such that the part to be bent protrudes from the equipment edge. They are then clamped such that the protruding part is cantilevered about the clamping edge. A wiping die is then used to apply a vertical force that bends the component to the required angle. This method is used to produce a variety of bends on iron plates.
Different Sheet Bending Processes
A channel folding is another process performed using specialized equipment. In this case, the machine has an upper and lower die. The two are made to various geometries that resemble the part to be developed. For example, a square punch will produce square shaped bend while a V or U shaped dies develops V and U groves respectively. The die is made such that the punch fits into it and is clamped on the lower surface of the device. Upon lowering the punch, the component is formed to resemble the curvature of the forming dies. This is a quick and economical method to develop most components. The use of this equipment is therefore very important in fabrication processes.
Corrugation is another common bending process. In this process, a special tool is used to produce a series of symmetrical grooves on the entire surface of the component. Corrugations have increased resistance to twisting and fracture. Depending on the shape of the die, different corrugations such as U, V or square corrugations can be made on the component. In the corrugation process both the punch and die are identical but one part is held stationary while the punch moves vertically. The metal plate is mounted between the two dies and subsequent pressing forms the corrugations. The device is also used to develop other complex sheet structures.
Metal materials are also applied for making creative ideas like art work, designer steel doors, window frames, etc. However, range of bending operation varies when compared to customary ones. The type of reforming that suits best for the above kind of application is channel bending. In some work requirements punch remains perfect choice of machining and in some die stays precise option because these two options support for machining requisites which must fit into pre-planned geometry. Special kinds of deforming is done by making use of exclusively designed die or punch formed by sheet metal channel. For example, “U” design can be made only by employing U shaped die and punch and similarly, semi rectangular or square designs are also made through exclusively pre-formed punch and die.
Description of Manufacturing Method
Spacer frame channel is the hot choice for modern construction requirements. Instead of tradition wood frames, channel forms offer greater as well as better benefits in terms of usability. It is created to add multiple provisions for glass fixture to make it easily slide between both directions. When it comes to manufacturing process, sheet metal bending equipment stays ideal to make such kinds of special bends using ferrous and non-ferrous ingredients. The following processes are included,
Series of V cutout elements are made through sheet metal tool
A corner is formed on each side of a flat strip so that when the channel is reformed on a transverse axis it is sent through apexes of V shaped cuts to provide perfect V design
Pairs of such cuts are set along the length and spacing is subsequently made.
The edges are fixed to remain parallel against one another.
For heavy weight applications the spacing arrangement is welded
Butt welding is also recommended to obtain perfect bondage from inside.
Merits in this Technology
This type of design helps to separate window panels and produce insulation. Consumer will be able to find one wall of window backed by second wall leaving space between the two. It prevents leakage and structurally provides good sealing. Customized requests can also be made by adding multiple channels. In recent days, people need flexible provision for ventilation including prevention of insect and dust entry. Presence of manifold channels are requested for in advance to add protective netted or plain glass or reflection preventing sheets as per their convenience or to suit climate.
Sheet bending equipment is a versatile tool that can be applied to meet our expectations for unique patterns. Automated devices of the same range are preferred in manufacturing industries for bulk production. For instance, construction and automobile sectors benefit highly through this while building works have heavy duty operations when compared to automotive industry.
Making channels from job material like steel aluminium through sheet forming device and bending to the desired dimension support for making window frames. This is an innovative production method that is performed using machining tool.
Deforming work materials into the determined dimension is quite expensive. If there is change in dimension, it leads to wastage and loss. In addition, manual bending process with the help of compact tools is complicated and challenging when it comes to obtaining precision. However, with the inception of special kinds of dies and machines deforming work piece can be managed cost effectively.
Matching the Template
For perfect bowing creation of template is more important as this would make the job easier and costs comparatively less. Though it is not necessary to produce templates for every sort of tooling requirement, this method is of great use for larger productivity requirements.
Ensure the Yield Strength of Work Component
Check out the type of material that must be shaped. This will help the operator to choose the right die or device that remains compatible, easier, faster and minimal wastage. For example, there is difference between deforming pipes and sheets. Next, materials like steel tubes, pipe, channels, bars, etc are some of the work materials which are liable for easier deforming when processed through turning operation
Economic Bending for Heavier Materials
As far as heavy range of job pieces are concerned, press stays the right choice of apparatus to do the twisting application. It runs on the basis of pressure that is provided until the desired dimension of twisting is reached. This technology is very effective to handle heavier beams, channels, tubes and bars. The maximum thickness and negotiable radius has to be considered for good machining result.
A bending device is an appropriate option for handling flat range of sheet materials wherein, the operation is carried over dotted lines around a straight axis. A press brake offers reciprocating motion to and away and at right angles as well. The punch and die are supporting features for creating twists using a press. Therefore, matching the device as per the production demand is one more way of obtaining economic tooling.
Operation Sequence Management
There exists a position of winding operation until which the action takes place without interference. Splitting the steps of sequence in the following is a great way to organize professional tooling,
First, the length of material is to match the total bend dimension required and must stay correspond to the gaps on both sides of the twist.
Secondly, avoiding part tool impact on either side of shaping point and with adjacent levels.
Planning the Process in tune with Budget
There involves a series of actions for planning the deforming process in the desired budget. They are,
Picking the appropriate tool
Calculation of blank length
Estimation of shaping force
Verification of Tolerance level similar to selected tools
Determination of sequence
Planning set up time,
Machine position up, material feed, etc
There are certain influencing features which may be followed to make the process influencing and stay in budget limits. These features will also support to minimize overall production span and bring in optimized style of machining at moderate investment.
Manufacturing of metal components involves application of metals as raw materials. When it comes to producing structural gadgets, a lot has to be done with work materials. Therefore, change in geometry of raw materials is highly required to obtain the precise shape or structure. The basic components that are received in the form of sheets or plates are deformed into the desired shape and there stays the change in geometry.
Process planning is the listing out of shaping works in accordance with the desired model that is required for producing final product. The actual process of deforming or de-shaping starts from here. The bending is required for industrial applications including steel almirah making, creation of bus structure, electric panel board, etc

This method is followed to cultivate the pre-planned shape or angle of bend required to make the desired manufacture. It helps to increase the rigidness of the sheet at the winding angle. Application of suitable tools like sheet bending machine can be employed at this stage to receive good resistance to meandering moments without causing damages to the work piece.
Increase heat indulgence capacity in work material
In some cases, heat indulgence capacity of worm material sheets may have to be increased for manufacturing purpose. During such requirements special kind of meandering called lancing can be applied as it helps to enhance heat indulgence or dissipation. This can be followed for multiple processes such as bending as well as cutting.
Application of tools to avoid material collapse
There are special ranges of tools like dies that can be incorporated with the existing machinery to obtain specific circuitous angle. These tools help to prevent material collapse as they are specially designed in accordance with the suitability of work material.
Reduce Setup and tool changes
Using complete machinery for deforming process is another way of reducing tool setup or tool change time as these two processed had been in usage since earlier times and they took more time for production.
Decreases Spring Back
Work materials in the form of sheets are available in different types. There are possibilities of sheets getting spring back at the time of twisting. Therefore using higher end equipment like sheet winding device can help to reduce spring backs.
Metal plate deforming equipment is a versatile kind of device that is featured with suitable features.

Bend Angle Requirements in Industries
It is the process of applying force through machines beyond the work piece materials yield point and not above its exact tensile capacity. The metal work piece is stretched by the force and compressed as per the required radius. The mid-point of the bend is considered to calculate the bend angle
Bend Allowance –An Important Operational Aspect to be followed in Metal Bending Equipment
Bend allowance is the final decision made on shape transformation in work metals. It requires good experience to calculate the bend angle with respect to the type of work piece provided. Since, not work materials vary in thickness bend allowance also has to be calculated based on the thickness and the time required to shape the metal.
What does Bend Size Signifies in Bending Operation?
Curving size is a synonymous term referred to bend angle. It is the shaping requirement expected in various industries. The bend size will not be the same always as it is pre-determined with respect to industrial application and compatibility of the work material.
Possibilities of Spring back analyzed in Industries
Spring back describes the elastic property of certain work metals which gets deviated a little after bending. It becomes quite difficult to manage such materials to achieve perfect bending.
Innovative Methods to Avoid Spring back
Only experienced operators can perform this operation to avoid spring back. They try to do little more circuitous than the predetermined angle to match the variation in curve caused by spring back action.
Measures Taken by Top Industries to Obtain Precision in Bend Angle
Many leading industries check for the compatibility of work metal with the curving operation. For example, aliminium is relatively lighter than iron and copper has different tensile strength, iron is considered to be the strongest. Hence, industries prefer to choose customized bending tools to match the material compatibility with machining.

With a sheet bending machine you can bend a sheet of metal. The whole sheet can be placed on the surface and bent according to your requirement to make metal structures. Pressure is applied to the metal sheet in order to bend it. Metal can be bent and converted into a new shape.
These are extensively used in many industries such as automobiles and manufacturing industry. Different types of sheet bending tools with diverse features are available.
Features of a sheet bending machine:
Also known as a brake, a sheet bending machine is used to make big right angles as well as curved folds. It is also used to shape metals in the required shape and size. High pressure exerted on the metal part causes it to deform and take the desired shape or the bend. Press brake is the basic form of this.
It has a flat surface on which the sheet to be bent is placed. The clamping bar holds the material firmly while it is being bent. The clamping of the sheet can be done manually, automatically or by using a foot pedal.
The metal to be shaped is placed between ‘punch and dies’ tools. The punch or the upper tool exerts pressure on the metal sheet and the die the base tool is formed into the shape which the metal will take when the force will be exerted.
The front plate of the device, is hinged and can be lifted like a gate. It forces the sheet to follow the plate in order to bend. The bends can be made up to 120°.
The clamping bar in a cornice brake is one solid piece, which is the size of the full length of the unit and it can make only straight bends. The complete width of the sheet can be bent.
A box and pan brake has a clamping bar with many blocks that can be removed. These blocks can be removed and arranged again to bend a particular area of the sheet.
These are available in different sizes depending upon you requirement. There are small devices for molding light metals like aluminum and brass which are operated by hand. For large sheets of steel there are industrial size machines which are hand operated or hydraulic.
It is hand operated have body made of cast iron. These have a handle, a bending bar and a bending blade to make folds on the metal sheets. Different dies are used to create different bends like rotary bending dies, V dies, radius dies, acute angle dies etc.

Sheet bending is a process of metal forming through which metals are bent into desired forms. In a sheet bending process the metals are casted into the required form by exerting a strong force on them. The force applied on the metal actually causes it to deform along one axis only but by applying the force repeatedly with a sequence of different operations the metals can be deformed along multiple axes thus forming the shape desired out of the metal piece.
In the process, the metal experiences both tension as well as compression. The tension will cause the outer part of the work piece to stretch further in the length where as the inside portion will experience the compression and will be shortened due to the force exerted. Apart from these two factors, the metal will also be subjected to residual stresses after the bending and these forces will try to slightly get back the metal to its original shape. For this reason the metal is often subjected to a little much bending than required so that the accurate sheet bending can be acquired in spite of the residual stresses acting on it.

Metals need to be casted into different shapes and sizes for various applications in different industries. They are normally very hard and therefore could not be bent or shaped easily. For bending and shaping of metals, a special category of unit is used called sheet bending or metal bending machines.
Types of Sheet Bending Machines
Different kinds of sheet bending equipments in various configurations are now available in the market. There are highly sophisticated models used in industries for bulk processes as well as those that are used in low production processes in small work shops or tool rooms on a work site. Some of the popular kinds are press brake, bending roller, shearing and power press metal forming.
Applications of Sheet Bending Machines
Sheet bending machine is mainly used to deform or shape metals into desired shapes and sizes. The metal is subjected to higher stress causing it to deform because of disturbance in its yield and tensile strengths. Here a strong force is applied on a metal part to be shaped causing it to deform in a particular direction. For metal to be casted into customized irregular shape, a sequence of operations are to performed on the metals with these sheet bending.
Press brake is one of the most important variant of sheet bending machine tool used for bending metal sheets and plates into customized shapes. Different kinds of press brakes are employed for metal bending applications in industries. Mechanical, pneumatic and hydraulic press brake models are most famous. Different metal forming jobs like curling, angled shaping, bending, bottoming, seaming, hemming etc. are possible with any of these press brakes by the use of various kinds of dies. Bending roller can be used for bending and straightening sheet metal covers and parts of boiler tanks, pressure vessels and converters where as shearing tool like mechanical and hydraulic shearing can be employed for cutting sheet metal to size out of a larger stock. Large sheets, bars and plates of metallic and non-metallic materials can be easily and accurately cut into different shapes with the help of shearing machine. Another important variant of sheet bending machine, called power press is the best metal bending equipment with which most accurate metal cutting, bending and shaping tasks can be executed for bulk industrial processes.
The act of bending metals into desired shape can be termed as sheet bending. In a normal sheet bending process force is applied on the metal causing it to deform in a particular direction and this mechanism is usually employed with the help of special kind of equipments called sheet bending. With this, one can deform the shape of various kinds of metals. Aluminum, brass, copper, steel, tin, nickel and titanium are few of them.
The sheet bending machines are robust equipments designed with parts like bending beam and die sets which help in carrying out customized metal bending. The metals are stressed beyond their yield and tensile strengths to give them the desired shape. They are actually deformed only along one axis but when sequence of different operations are performed on them, even the complex shapes can be casted with sheet bending. Continue reading →
Different kinds of machines are employed for sheet metal forming tasks in industries like lathe, sheet bending, power press, press brakes etc.
It is a special kind of sheet bending machine that is designed to meet tougher metal bending requirements in industries. It applies direct strain about the metal sheet and alters it to the desired form. It is commonly utilized all over the entire world to mold all types of metals into different designs. Aluminum, brass, copper, steel, tin, nickel and titanium are some common metals which can be bent into desired shapes using a press brake.
To bend metal using press brake it is first of all inserted in the jaws of press brakes. It is placed between the two tools of machine called punch and die. Punch is the upper tool which exerts force on metal sheet and bends it, while the die is the lower tool of the machine having a specific design. It is in this design that the metal will be casted. For bending, the sheet is placed on the die and held in place by the back gauge while the punch lowers and forces the sheet to bend according to shape of the die. Once this is done, in normal cases the sheet tries to regain its normal position because of the residual stresses acting on it and therefore the sheet is usually over-bent to achieve a proper bend angle.
There are basically three basic types of bending performed using a press brake; air bending, bottoming and coining. In air bending, material is formed by pressing a punch into the material into a bottom V-die. Disadvantage of this method is that it is not as precise as other methods and stroke depth must be kept very accurate. Variations in the thickness of the material and wear on the tools can result in defects in parts produced. Bottoming is similar to air bending. Here also the sheet is forced against the V opening in the bottom tool but the advantage of this method is that it provides greater accuracy and less spring back than air bending. A different tool set is needed for each bend angle, sheet thickness, and material and therefore in general, air bending is the preferred technique in this case. The third process is coining in which the top tool forces the material into the bottom die with five to 30 times the force of air bending. It causes a permanent deformation through the sheet with very little or approximately no spring back at all. This means that with coining high precision can be attained but due to its higher costs it is not often used.
To perform bending, today different ranges are available in the market. Depending on the type of force used for bending, there are 4 different type of brakes; mechanical, pneumatic, hydraulic, and servo-electric. Depending on accuracy, speed and quantity of bending to be performed, one can select the best one for their applications by considering factors like work pieces to produce, inner radius required, accuracy, tooling, flange width etc.
The term tool refers to the category of machinery which is generally powered electrically or hydraulically or by any means other than human effort. These are widely used to make manufactured parts or components in various ways that include cutting or certain other kinds of deformation. By constant research and day-by-day developing technical strategies, today a wide range of tools have evolved to make the industrial processes simplified and easier to work out.
A milling device is definitely is one of the best examples of tools that have evolved to make solid material machining processes in industries simpler. With the help of this one can perform a vast number of operations ranging from simple tasks like slot and keyway cutting, planing, drilling to complex operations like contouring and die sinking. There are two categories now available in market. They are horizontal milling and vertical milling where horizontal and vertical refers to the orientation of the main spindle of the device.
