[0002] The stamping and welding process of the automobile body mainly includes two main steps: stamping and welding. The stamping process is the first step in automobile manufacturing. The steel plate is stamped into workpieces of various shapes through the mold. The quality of the mold directly determines the quality of the workpiece, and the exquisiteness of the stamping process is related to the stability of the entire body. In automobile manufacturing, punching is an indispensable processing procedure. Almost all the processing of major parts is inseparable.

The suction cup mechanism 5 is composed of a first bracket 22, an air valve 23 and a suction cup 24.

[0027] In one embodiment, Figure 1 As shown, the punching die 2 is provided with a plurality of positioning mechanisms 6 ; the positioning mechanisms 6 are used to fix the upper body of the automobile on the punching die 2 .

[0028] In one embodiment, Figure 5 As shown, the positioning mechanism 6 includes: a second bracket 26, fixedly mounted on the punching die 2; a fixing frame 27, fixedly mounted on the second bracket 26; a first rotating arm 28, rotatably mounted on the fixing frame 27; a second rotating arm 29, one end of which is fixedly connected to the first rotating arm 28; a control arm 30, fixedly connected to the first rotating arm 28 and rotatably connected to the second bracket 26; a positioning block 31, fixedly mounted on the other end of the second rotating arm 29; and a photoelectric sensor 32, fixedly mounted on the fixing frame 27.

When the fixation is completed, the punching mechanism 3 works, and the first cylinder 10 works, and drives the first punch base 11 to move upward by using the first slider 9 and the first guide rail 8 through the telescopic rod. When the pre-pressing die 12 is against the table panel 1, the pre-pressing die 12 stops moving upward, and the first punch base 11 continues to move upward. At the same time, the spring bolt between the pre-pressing die 12 and the first punch base 11 is compressed, so that the punching knife 13 on the first punch base 11 passes through the pre-pressing die 12 and the table panel 1 to punch the upper body, and at the same time, the second cylinder 15 also works, and drives the punch lower die 16 through the telescopic rod to punch the upper body at the same time.

[0030] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
