What is a busbar bending machine?

A busbar bending machine is a mechanical device designed to bend rigid busbars with high accuracy. Busbars, also known as bus ducts or electrical busways, are flat conductors used for transmitting electrical power within electrical switchgear, distribution boards, and other power distribution systems. Busbar bending machines are specifically designed to handle the bending requirements of these solid and heavy conductors.

How does a busbar bending machine work? 4 steps

Busbar bending machines utilize hydraulic or electric-powered systems to generate force and bend the busbars. The working mechanism typically involves the following steps:

  • Preparation: The operator sets up the machine by adjusting the necessary parameters such as bending angle, bending radius, and length of the busbar.
  • Clamping: The busbar is securely clamped into the machine using special clamping tools or fixtures to prevent movement during the bending process.
  • Bending: The machine’s bending mechanism, which can be hydraulic or electric, applies force to the clamped busbar, causing it to deform and achieve the desired bend shape.
  • Unclamping: Once the bending process is complete, the clamps are released, and the bent busbar is removed from the machine.

Different 5 types of busbar bending machines

  • a) Manual Busbar Bending Machines: These machines are operated manually, where the operator exerts physical force to bend the busbars. Manual machines are suitable for low-volume or occasional busbar bending tasks and are typically more affordable.
  • b) Hydraulic Busbar Bending Machines: Hydraulic machines utilize hydraulic power to provide high bending force, making them ideal for bending thick and heavy busbars. They offer precise control and can handle a wide range of bending angles and radii.
  • c) Electric Busbar Bending Machines: Electric machines employ electric motors to generate bending force. They are commonly used for lighter busbars and offer quick operation, automation features, and ease of use.
  • d) CNC Busbar Bending Machines: Computer Numerical Control (CNC) busbar bending machines are advanced models equipped with programmable controls and automation capabilities. These machines offer high precision, repeatability, and are suitable for large-scale busbar production.

Final Words

Busbar bending machines play a crucial role in the efficient fabrication of busbars for various electrical applications. Understanding their working mechanisms and the different types available can help users choose the most suitable machine for their specific bending requirements. Whether it’s a manual, hydraulic, electric, or CNC busbar bending machine, these tools enhance productivity and accuracy while simplifying the busbar fabrication process.
