Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Referring to fig. 1-5, the rapid punching and hemming structure includes a punching punch 2 for performing a punching process on a metal member 1, wherein the punching punch 2 includes a connecting portion 21, a hemming portion 22 and a punching portion 23 sequentially arranged from top to bottom;

the punching part 23 and the connecting part 21 are both cylindrical, the curled part 22 is conical, and the outer diameter thereof is gradually reduced from top to bottom;

the upper end of the connecting part 21 is provided with a first transmission mechanism 31 which enables the punching punch 2 to do reciprocating motion in the vertical direction, a curling pressure head 4 is arranged below the punching punch 2, a punching groove 41 corresponding to the punching part 23 and the curling part 22 is arranged on the curling pressure head 4, a second transmission mechanism 32 is arranged below the curling pressure head 4, the curling pressure head 4 makes reciprocating motion in the vertical direction, the punching part 23 and the curling part 22 sequentially punch and curl the metal piece 1 in the process of pressing down the punching punch 2, and then the curling is pressed by the curling pressure head 4, as shown in fig. 5, the metal part 1 can be fixed by the fixing member 5 in the machining process, and those skilled in the art can understand that the metal part 1 can rapidly complete three processes of punching, flanging and edge pressing in one device, and workers do not need to perform device conversion on the metal part 1, thereby improving the working efficiency.

Further, the included angle between the outer side edges of the curled part 22 and the perforated part 23 on the same vertical bisection plane is A, and 155 degrees is more than A and less than 165 degrees.
