Based on the usage environment of copper busbars in the new energy industry, higher requirements are put forward for the structure and performance of copper busbars.

[0003] The processing technology of copper busbars in the prior art is relatively complex. The riveting process is adopted, and the size of the product cannot be miniaturized. At the same time, it is easy to cause poor contact of the terminals, reducing the current-carrying voltage and conductivity. Summary of the Invention

The manufacturing method has simple steps. It not only reduces the processing allowance, changes the flat structure of the traditional copper busbar, but also makes the structure more stable and reliable, reduces the riveting process, significantly reduces the size of the product appearance, and at the same time avoids the phenomenon of poor contact of terminal riveting, improves the current-carrying voltage of the copper busbar, and improves the conductivity.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A manufacturing method of a copper busbar for new energy vehicles, characterized by including the following steps:

[0007] 1) Cutting the material

[0008] a. First, cut the sheet through a cutting machine to form the required size, and sort out the cut sheet.

[0009] b. Then, deburr the sheet in sequence.

[0010] 2) Turning a frustum

[0011] Feed the cut sheet into a lathe, and form a frustum along the top surface of the sheet through the lathe. Put the workpiece after turning the frustum into a pusher cart.

[0012] 3) Stamping and trimming

[0013] a. First, take out the workpiece after turning the frustum from the pusher cart through a manipulator and place it on the lower die assembly in sequence until the lower die assembly is filled with workpieces.

[0014] b. Then, the lower fixture assembly is pushed along the slide rail to the lower part of the stamping and trimming mechanism by the boosting mechanism on the processing table and limited by the blocking mechanism.

[0015] c. Next, start the stamping and trimming mechanism to stamp and trim the workpiece in the lower die assembly, so that the required external shape structure is formed on the workpiece. Then, withdraw the stamping and trimming mechanism, and pull the lower die assembly back along the slide rail to directly above the guide through holes on the processing table. The guide through holes are evenly distributed on the processing table. A limiting groove is provided on one side of the guide through hole, and the limiting groove vertically penetrates the processing table. The guide through hole communicates with the limiting groove.
