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.

Properly guarded power press with interlocks is good for safety and easy operations.
It is used for bulk production from cold working of ductile materials like mild steel with rotating flywheel acting as energy storehouse to operate ram to impact on the workpiece. It is used to operate various functions with bed, plate, bolster and ram. Knock out mechanism is used to eject the furnished work piece from power press. Proper cushioning must be there beneath the bolster, when heavy effect is given to the workpiece. There are different types are available in the market such as c type and pillar type for sheet metal machining work is used in manufacturing industry. C type is designed in such a way for continuous production with accuracy. The frames are of solid steel fabricated with suitable cross ribbing. The clutch gives continuous strokes for mass productions. Crank shaft is made of special alloy steel and fitted in with gun metal bushes for smooth working and longer life. Table and ram are perfectly aligned to each other to get high precision power press execution.
Power Press – Types & Applications
Various applications are applied like bending, curling, piercing, deep drawing etc. Automation makes the power press faster, which is the main requirement of production industry now a day to save money and time. Thus research and development is going on for these heavy machinery to make them more effective for the functions, high production, least wastage of raw material and easy operation with best protection guards to secure the operator’s life along with technical enhancements like speed of the power press, width of the stock etc. continuous feed of the stock is a complex process which requires to be streamline and easy to be done in proper manner. Accuracy is required for better production through power press; otherwise it can create the defective piece leads to wastage and production loss. It also has a great advantage when you require more complex shapes formed into the sheet metal. It is defined as mechanical, hydraulic and pneumatic. It consisting mechanical parts, clutch and brake assemblies, electrical systems, tooling or dies, safeguarding controls, material handling etc. hydraulic power press is designed on Pascal’s principle that pressure throughout a closed system is constant. OSHA and ANSI standards are defined for safety measures.
Safety Controls for Power Press
It is a machine needs to handle carefully by skilled operator with proper training. A little mischief can lead to a serious accident if not taken care. Thus need to take care of hands, fingers, arms and other body parts while operating the machine. Proper safeguards, frequent inspections, employee training and regular press maintenance are vital to the prevention of any injuries. The operator must take care where stock is inserted, held or withdrawn by hand. It is designed in such a way which eliminates the possibilities to place any body parts in contact with hazardous moving parts. Operator must know the importance of safeguards and never remove or alter with the safeguards. Extensive training on different types of press machine can make the person more skilled to handle power press efficiently without any injury.
Power Press – C Type Power Press, Pillar Type Power Press
Power presses are powered equipment used to stamp, cut or form materials by the use of dies (or tools). They include equipment known as “croppers” or “metal workers”. These are large machines with C type and Pillar type. These machines have a table or bed with brushes or roller to allow the sheet metal workpiece to traverse with low friction. Power press ‘C’ type is available in various tons capacities. This type of machine is used for high quality production. Pillar type is known for its high performance, efficiency, durability, low maintenance, easy installation with fast production. It is heavy machine to operate carefully to avoid injuries in metal machinery workplaces. They are considered to be at high risk machines. This machine must be guarded well with safety measures and regular maintenance is must to avoid any malfunctioning leads to serious injury. Nobody has to be in overconfidence while operating this machine. Ensured is must that machine guards are working well. 50% of power press injuries are caused by relying on the operator to synchronize the movement of their hand with the operation of the foot pedal. The machine operator must be properly trained and experienced to operate it well with caution. Continue reading →
“Power press” means a press or press brake for the working of metal by means of tools, or for die proving, which is power driven and which embodies a flywheel and clutch. Pillar type is highly precised combined with accuracy and most suitable design for various tough jobs. The primary function of the said type of power press is to resist the forces created during operation and maintenance of proper die alignment. Pillar type has fast speed and low noise for maximum output. This pillar type and C type available in different models based on crank shaft diameter, stroke adjustment, hole in ram, hole in bed, dist. bed to ram, stroke per minute and many other factors. C type’s is best suitable for Engineering, automobile, electrical, agriculture, bicycle industry etc for trimming, straightening, pressing, assembling and disassembling of various components. Industrial Hydraulic owing the features like robust construction, energy efficient and durable, which is used for extensive hydraulic applications in various industries.
Power Press Safeguards
It is designed in size by the force which can be generated from 5 ton to 250 ton capacity. Due to heavy pressure, it requires to have safe operation with active safeguards, automation and reliability of the control system, the tooling condition with feed mechanism and work area for power press. Training, awareness and strict observation, safe work practice is must to operate the machine securely. The operating controls like mode selector, palm buttons, top stop, foot switch and emergency stop etc should be in good working condition. The guard or safety controls must positively prevent body access into the danger zone. The sides and back of the machine should be guarded or placed in such a manner that nobody should be injured by any part of the machine. Check well before operating that safety controls are working well. Die area must be cleaned without any slugs or debris while operating. The press guard must be designed in such a way to place parts into the die easily. It operation needs skilled, experienced and well trained operator.
Power Press Check List for Safety Measures
Every operator must check well before starting his work and should confirm his check list for safety measures like nothing should be placed scattered on the machine like turnover bar, die block on the power press. The operator must know the maximum thickness or gauze and type of metal which the tooling can safely run. There should not be any vibration or squealing, shuttering, clicking, clanking from the machine. Die stripper, take-up reel should work properly during operation. Die should not bind or jam due to the tooling, the press or due to the stock. Always use proper protection for eye, face and body during press brake operation.
