Embodiment 1
[0057] refer to figure 1 , In this embodiment, a manufacturing process of the copper shell is proposed, and the copper shell is processed and manufactured through the manufacturing process of the copper shell. Among them, such as figure 2 with image 3 As shown, it is a schematic diagram of a finished product 100, that is, a copper shell.
[0058] The manufacturing process of the copper shell comprises the following steps:
[0059] S1: initial punch, used for punching the copper sheet, the convex part formed on the copper sheet, the inside of the convex part is formed with a concave structure 101 due to stamping.
[0060] S2: Forming, which is used to stamp the concave structure 101 multiple times to obtain a semi-finished product with the same size as the finished product 100 . The raised portion is stretched by punching, and the stretched length of the raised portion is between 0.5 and 2 mm for each punching, and at the same time, the wall thickness of the raised portio...
Embodiment 2
[0064] Such as figure 2 with image 3 As shown, it is a schematic diagram of a finished product 100, that is, a copper shell. In order to make the copper shell, a mold for making the copper shell is proposed in this embodiment.
[0065] refer to Figure 4 with Figure 5 , the mold used to make the copper shell includes an upper mold base 1000 and a lower mold base 2000 parallel to the upper mold base 1000 , and the upper mold base 1000 is located directly above the lower mold base 2000 .
[0066] Such as Image 6 with Figure 7 As shown, the upper die base 1000 is provided with a first punch 1001 , and the lower die base 2000 is provided with a first ejector pin 2001 corresponding to the first punch 1001 .
[0067] The first punching pin 1001 and the first ejector pin 2001 punch the copper sheet, and the convex part formed on the copper sheet has a concave structure 101 inside the convex part due to punching.
[0068] The upper mold base 1000 is also provided with a fo...
