Description

Technical Field

[0001] This utility model relates to the field of copper busbar bending technology, and in particular to a bending fixture for copper busbar production. Background Technology

[0002] Busbars refer to the copper or aluminum busbars that connect the main switch and the switches in each branch circuit in a power supply system. In fact, these are all connecting pieces used in the process of connecting electronic devices. Busbars include copper busbars and aluminum busbars, and are sometimes also called busbars or copper busbars.

[0003] The production of copper busbars requires the use of bending machines, and bending fixtures are installed on these machines. In small-scale copper busbar manufacturing enterprises, multiple processing stations are located close to each other; for example, grinding and bending of copper busbars are carried out continuously in one area. This causes dust and impurities from other stations to easily fall onto the bending fixtures. If not cleaned promptly, these metal impurities can form indentations on the copper busbars during the pressure bending process, affecting the quality of the copper busbars. Therefore, this utility model proposes a bending fixture for copper busbar production to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a bending fixture for copper busbar production. By setting a dust blowing component on the side wall of the mounting base of the drive mold assembly, the first and second dust blowing nozzles connected to the dust blowing component can blow air onto the lower end of the lower pressing template and the bending groove, preventing metal impurities adhering to the surface of the lower pressing template and the bending groove from forming indentations on the surface of the copper busbar.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bending fixture for producing copper busbars includes a drive mold assembly and a fixed lower mold assembly, which are arranged vertically opposite each other. The fixed lower mold assembly is located on the top of the workbench of the bending equipment, and the drive mold assembly is located at the output end of the drive cylinder of the bending equipment. The drive mold assembly includes a mounting base and a pressing template. The mounting base is installed at the output end of the drive cylinder and has a mounting groove.

A first fixing seat is provided on one side wall of the mounting base, and a second fixing seat is provided on the housing of the drive cylinder above the first fixing seat. The first fixing seat has a mounting rod and a dust blowing assembly. A trigger switch is provided at the bottom of the second fixing seat. The trigger switch is electrically connected to the controller of the dust blowing assembly, and the position of the trigger switch is adapted to the position of the mounting rod. A first dust blowing nozzle and a second dust blowing nozzle are provided on one side of the mounting rod, and the dust blowing assembly connects the first dust blowing nozzle and the second dust blowing nozzle.

[0007] A further improvement is that the fixed lower mold assembly includes a lower mold base and a lower template. The lower template is installed on the top of the lower mold base by fixing bolts, and the lower template is provided with a bending groove that matches the position of the lower pressing template.

[0008] A further improvement is that the first fixing seat is detachably installed to one side wall of the mounting seat via fixing bolts, and the second fixing seat is detachably installed to the housing of the drive cylinder via fixing bolts.

[0009] A further improvement is that the dust blowing assembly includes an air pump and an air pipe, the first fixed base is provided with an air pump, the output end of the air pump is provided with an air pipe, and the first dust blowing nozzle and the second dust blowing nozzle are both connected to the air pipe.

[0010] Further improvements include: the mounting base has a first groove symmetrically arranged on the front side, an infrared transmitter is provided in the first groove, the lower template has a second groove adapted to the first groove, an infrared receiver is provided in the second groove, and an alarm is provided on the front side of the housing of the drive cylinder.

[0011] A further improvement is that after the output end of the drive cylinder is reset, the mounting rod abuts against the trigger switch, and the first and second dust-blowing nozzles are respectively aligned with the lower end of the pressing template and the bending groove.

[0012] The beneficial effects of this utility model are as follows: This utility model sets the bending fixture to consist of a drive mold assembly and a fixed lower mold assembly, and sets a dust blowing assembly on the side wall of the mounting seat of the drive mold assembly. The first dust blowing nozzle and the second dust blowing nozzle connected to the dust blowing assembly can blow air onto the lower end of the lower pressing template and the bending groove, preventing metal impurities attached to the surface of the lower pressing template and the bending groove from forming pressure pits on the surface of the copper busbar. The control of the dust blowing assembly of this utility model is synchronized with the action of the drive cylinder, which has the advantage of being easy to use. It can blow air to remove impurities from the lower end of the lower pressing template and the bending groove before each bending production.

[0013] This invention creates a safety light grid in front of the bending processing area by setting up an infrared transmitter and an infrared receiver.
