SunShine® Busbar Machine Tutorial: How to Use a Busbar Bending Machine

The correct use of busbar bending machines can not only improve production efficiency, but also ensure the processing quality of busbars, thereby ensuring the safe and stable operation of the entire power system. This article will introduce in detail how to use the busbar bending machine, including equipment preparation, operating steps, precautions and common problem…

The busbar bending machine is an essential apparatus in the electrical sector. It is employed to accurately bend busbars so that these can satisfy the power systems specifications concerning their shapes and sizes. Properly using busbar benders does more than just increase how quickly projects are done; it also helps make certain that all components are processed properly, ultimately protecting and maintaining a secure overall Power System operation. In this chapter we will present what a bus bar bending machine is, how it should be used, its equipment preparation, operating steps, precautions and some of the common problems encountered and their handling.

Equipment Preparation

Some preparations have to be made on the equipment before using the busbar bending machine. Firstly, see if the power cord and grounding wire are well joined with the device so that when switching it on, there is normal flow of safe electricity in it. Afterward, evaluate if there are any damages on bending moulds, clamps being among some critical parts of concern in this case. Such defects would require immediate replacements. Also, it is important to lubricate and maintain the equipment appropriately for its smooth running and prolonging its useful life span.

Steps of operation

Step 1: Adjust the mold and fixture
Depending on the given specifications and bending requirements for the busbar, choose suitable molds and fixtures then mount them on the busbar bending machine. Ensure that the positioning of the mold and fixture is exact and secure.

Step 2: Determine the bending parameters
For this step, you will have to set some values regarding the material, thickness as well as angle of bend on bus-bar then; Make sure to set bending strength, speed, angle and other related parameters in such a way that they satisfy the requirements of processing but do not harm busbars themselves.

Step 3: Position the Bus-bar
Place between the moulds the busbar that requires bending ensuring its correct position but being observant of certain rules. Remember that it should be done only in such a way when the direction of placing is similar with a bending one or there may occur back bending.

Step 4: Turn on equipment
The power switch of the bus bar bender needs turning “on” followed by starting the equipment. As you operate machinery make sure that everything is fine including minor details like bending of busbars themselves.

Step 5: Completion of bending
Afterwards, turn off the power switch of the machine immediately as soon as you see that it has reached a point whereby it is bending. Take out the bent bus bar then check its shape and size vis-à-vis predetermined specifications. Equipment parameters must be adjusted immediately or another bending process carried out if those conditions are not met.

Operation precautions

  1. Safety should be observed: Strict compliance with safety rules is essential in operating busbar bending machines to guarantee user’s security. It is especially important to keep a safe distance while working with the device so that nothing bad happens.
  2. Carry out regular checks: Ensure proper functioning of the busbar bending machine and increase its durability through routine servicing. Switch off the machine for examination immediately on noticing any form of abnormality or malfunction in it.
  3. Adjust parameters reasonably: Modify the bending parameters appropriately depending on the actual busbar conditions so as not to cause any harm to it or equipment failure due to this reason.
  4. Maintain hygiene: Ensure cleanliness in the busbar bender, remove dirt from its surfaces on a regular basis, and take care of any other waste particles. Pay extra attention to cleanliness and smoothness of major parts like moulds and clamps; this will help improve machining accuracy and prolong service life.

Frequently Asked Questions

1. Whats is wrong when I get wrong bend angle at my copper bar?
Incorrect mold position installation, unsuitable parameter setting for bending or breakdown within apparatus may explain this issue. For treatment, one may recommend adjusting the mold location again, changing bending data, or inspecting the machinery to rectify any faults identified.

2. What causes defects on the surface of copper bars?
Copper bar surface damage may result from uneven mold surface, extremely tight clamp, or high-speed bending actuator. Remedies here involve substituting the mold, changing clamp force or slowing down on bending pace.

3. What if equipment malfunctions?
Equipment malfunction might arise from disconnected power supply cord, faulty motor, or injured transmission spares. The solution is to check if power cords are well connected; if not then mend motors or change transmission part with new one.
