[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] This application provides two technical solutions, specifically including the following embodiments:

[0031] Embodiment 1

[0032] In this embodiment, refer to Figures 1 - 5, A special-shaped contact processing device, including a stamping device 1. An inlet conveying pipe 8 is installed outside the stamping device 1 for conveying the workpiece body 12. The inlet conveying pipe 8 is used to convey tubular blanks. By conveying the blank to the stamping station and then stamping to form a chamfer;

[0033] In this embodiment, specifically, the contact is made of copper-chromium alloy or aluminum alloy;

[0034] In this embodiment, further, a rectangular limiting frame 3 is fixedly installed inside the stamping device 1. A driving shaft rod 13 is rotatably connected inside the rectangular limiting frame 3. A plurality of forming bottom dies 11 are fixedly installed on the outer side of the driving shaft rod 13. The forming bottom dies 11 are used to rotate with the driving shaft rod 13 to convey the workpiece body 12 to the stamping station. The forming bottom dies 11 are used to realize the forming and conveying of the workpiece body 12. When the workpiece body 12 inside the inlet conveying pipe 8 reaches inside the forming bottom die 11 through conveying, it can run with the forming bottom die 11 to transfer the workpiece body 12 to the stamping station.

[0035] In this embodiment, specifically, a forming moving die 10 is slidably connected up and down inside the rectangular limiting frame 3 for stamping the workpiece body 12. The forming moving die 10 is used for the forming operation of the workpiece body 12. As the forming moving die 10 moves downward, the upper end of the workpiece body 12 is stamped and chamfered by the conical body at the lower part of the forming moving die 10; Refer to Figure 9 , Since this process is only used for stamping the chamfer 1201 at the upper end of the workpiece body (thin-walled tube), the stamping force is small. Therefore, a driving shaft rod 13 with a certain diameter can meet its support needs.

[0036] In this embodiment, specifically, the existing chamfer forming method of the contact is usually by turning or milling. By using the stamping method in this application to realize chamfer forming, the forming effect can be guaranteed and the operation efficiency can be further improved.

The end of the connecting pipeline is rotatably connected to the driving shaft rod 13. When the device is in the process of conveying and stamping, through the operation of the negative pressure device, the forming bottom die 11 can generate an adsorption force through the negative pressure suction holes 1101 to adsorb the workpiece body 12 inside it, effectively improving the processing stability of the workpiece body 12.

[0039] In this embodiment, specifically, a through groove extending along the length direction is provided at the upper part of the feed conveying pipe 8, and multiple elastic conveying rollers 9 are rotatably connected inside. Specifically, a plurality of mounting holes are provided on the pipe wall of the feed conveying pipe 8 (i.e., at the position of the through groove). The roller shafts of the elastic conveying rollers 9 are assembled with the mounting holes through bearings. A transmission belt 901 is rotatably connected between the roller shafts of the multiple elastic conveying rollers 9 for conveying the workpiece body 12 inside the feed conveying pipe 8.
