A busbar is a metallic strip or bar that is used in electric power distribution. It is employed for local high current power distribution and is fitted inside the switchgear, panel boards, and busway enclosures. They are generally kept uninsulated and are employed to connect high voltage equipment at electrical switchyards, and low voltage equipment in battery banks. A busbar has sufficient stiffness to be supported in the air by insulated pillars.
Busbar Bending-Cutting-Punching Machine
A busbar bending-cutting-punching machine is technologically advanced machinery capable of performing the operation of bending, cutting, and punching simultaneously. It is used for producing a busbar and is capable of performing almost all the required operations. The machine has very high productivity and hence is synchronous with the growing demands of the numerous industries. The busbar machine has an independent station for performing the operation of bending, cutting, and punching. These stations perform the required task in parallel, thus ensuring higher rates of production.
Bending is a type of manufacturing process and it is used to produce a V-shape, U-shape, or channel shape along the straight axis in ductile materials, mostly sheet metals. The bending machine also has special tools for its bending station. The bending tool is unhardened & ungrounded and the speed at which the bending operation is carried out is 5mm/Sec. The machine also consists of a gauge stopper.
Another operation which the machine performs is that of cutting. The workpiece is being cut into the desired length with the help of the busbar cutting machine at the cutting station. The shearing station boasts of a hardened & grounded HCHCr Blade to carry out the cutting operation effectively. The cutting machine performs the cutting operation at the speed of 6 strokes/min. The oil tank capacity of cutting station is about 75 liters. The station is powered by a 5HP motor that is equivalent to 3.7KW. It also comprises of a gauge stopper.
The busbar punching machine has one suitable die & punch on its punching station. Punching is a forming process in which a tool is forced through the workpiece to create a hole by shearing. The machine has a separate foot switch for every station, i.e. punching, cutting, and bending. There is a provision made for special tools at the punching station of the machine. The punching operation is performed at its station with a speed of 13 strokes/min.
The busbar bending-cutting-punching machine is a highly compact and versatile machine. The machine is powered by the main drive motor. It comprises of a compact hydraulic power pack with a built-in control panel. The machine is highly durable and capable of giving out higher outputs. A high-speed version of the machine is also available. It boasts of hydraulic and electrical components of international standards that ensure the long life of the machine without any requirement of maintenance.
Summary: The machine has 3 different stations for bending, cutting, & punching. These 3 operations are carried out at their respective stations and thus it proves to be a versatile machine. Gauge stopper is provided at all three stations. The punching station consists of one suitable die & punch.
The Bottom Line: A busbar is being extensively used for electric power distribution. It is manufactured using a busbar bending-cutting-punching machine. The machine has separate stations for all the 3 process and thus the simultaneous operations help in greater productivity. The machine is also available in a higher speed version.
