Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone metal panel processing, in particular to a punching device for mobile phone metal panels. Background Technique

[0002] In the production process of mobile phone metal panels, the punching process is a very important link. Various shapes and sizes of holes are formed on the metal panels through punching equipment. In the prior art, the equipment for punching mobile phone metal sheets includes a workbench, and a punch is arranged above the workbench. When the equipment is started, the punch moves downward to achieve punching of the mobile phone metal sheets. When the existing punching equipment punches the mobile phone metal sheets, due to the insufficient clamping stability of the metal sheets, displacement is likely to occur during the punching operation, resulting in inaccurate punching positions and a high rejection rate of punching.

[0003] The Chinese patent discloses a punching device for mobile phone metal panels (publication number CN108856470A). In this patented technology, the mobile phone metal panel to be punched is placed on the top plate, and the metal panel to be punched can be clamped by using the clamping blocks. By starting the above-mentioned first cylinder, the punching operation of the mobile phone metal panel can be quickly realized, which can improve the punching efficiency and ensure the production quality of the metal panel at the same time.

[0004] However, it has certain drawbacks: after punching is completed, manual blanking is required, which increases the labor intensity of the operators. Compared with automated operation, the efficiency of manual operation is significantly lower, and when manual operation is involved in the blanking process, the operators need to be close to the punching equipment, increasing the risk of being injured by the punching equipment.

The second telescopic cylinder 7 extends to drive the clamping block 8 to clamp the mobile phone metal panel 21 in the left and right directions; then, the third telescopic cylinder 11 extends to drive the lifting plate 12 to descend, thereby driving the vacuum adsorption mechanism 16 to press the mobile phone metal panel 21; the first telescopic cylinder 2 extends to drive the punching head 3 to punch the mobile phone metal panel 21. After punching is completed, both the first telescopic cylinder 2 and the second telescopic cylinder 7 retract. Subsequently, the vacuum pump 17 evacuates the vacuum to adsorb the mobile phone metal panel 21 through the vacuum chuck 19. The third telescopic cylinder 11 retracts to drive the mobile phone metal panel 21 away from the surface of the support base 1. The motor 13 rotates counterclockwise by 180 degrees to drive the mobile phone metal panel 21 away from the support base 1. The vacuum adsorption mechanism 16 releases the mobile phone metal panel 21, thus completing the automatic punching and blanking of the mobile phone metal panel 21.
