Description

Technical Field

[0001] The utility model relates to the technical field of air bag shell processing, in particular to an anti-jump waste punching mechanism. Background Art

[0002] An airbag is a flexible rubber capsule filled with compressed air or water. The airbag uses the compressibility of air and the fluidity of water to achieve elasticity. When producing the airbag, the shell needs to be stamped. When the shell is stamped, waste is easily brought out, so a waste stamping mechanism is needed to prevent jumping. Utility Model Content

[0003] The utility model aims to provide an anti-jump waste stamping mechanism to solve the problem in the above background technology that when producing an airbag, the shell needs to be stamped and waste is easily brought out during the stamping of the shell.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a waste punching mechanism to prevent jumping, including a lower die and an upper punch, the upper punch is arranged above the lower die, one end of the upper punch is provided with a terminal, the inner side of the lower die is provided with a pressing groove, and the inner cavity of the pressing groove is provided with limiting components on the front and rear sides.

[0005] Preferably, the end is arranged in a V-shaped structure.

[0006] Preferably, the limiting assembly includes a convex rib.

[0007] Preferably, the convex ribs are fixedly connected to the front and rear sides of the inner cavity of the pressing groove.

[0008] Compared with the prior art, the beneficial effect of the utility model is that when the anti-jump waste punching mechanism is in use, the end of the upper punch is V-shaped, and the flat waste will not be adsorbed together with the end after punching, and the waste will naturally not be brought out, and the convex ribs are added to the inner wall of the pressing groove, which can clamp the waste and prevent the waste from going upward, thereby preventing the waste from being brought out by the end, thereby achieving the effect of preventing the waste from being brought out.

[0016] Example

[0017] See also Figure 1-4 The utility model discloses an anti-jump waste punching mechanism: it comprises a lower die 1 and an upper punch 2, the upper punch 2 is arranged above the lower die 1, one end of the upper punch 2 is provided with a terminal 3, the inner side of the lower die 1 is provided with a pressing groove 4, and the front and rear sides of the inner cavity of the pressing groove 4 are provided with limiting components. When in use, the terminal 3 of the upper punch 2 is V-shaped, and the flat waste will not be adsorbed together with the terminal 3 after punching, and the waste will naturally not be brought out, and the inner wall of the pressing groove 4 is increased with a convex rib 5, which can clamp the waste and prevent the waste from going upward, thereby preventing the waste from being brought out by the terminal 3, thus completing the effect of preventing the waste from being brought out.

[0018] In order to prevent waste from being carried out, the end 3 is arranged in a V-shaped structure.

[0019] In order to prevent waste from being dragged out, the limiting component includes a convex rib 5.

[0020] In order to prevent waste from being carried out, the convex ribs 5 are fixedly connected to the front and rear sides of the inner cavity of the pressing groove 4.

[0021] Working principle: When in use, the end 3 of the upper punch 2 is V-shaped. After punching, the flat waste will not be adsorbed together with the end 3, and the waste will naturally not be brought out. The convex rib 5 is added to the inner wall of the pressing groove 4 to clamp the waste and prevent the waste from going upward, thereby preventing the waste from being brought out by the end 3, thereby achieving the effect of preventing the waste from being brought out.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the implementation rules without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
