Description

Die structure capable of simultaneously realizing punching and flanging

Technical Field

The utility model relates to a realize turn-ups's that punches a hole mould structure simultaneously belongs to car punching press part technical field.

Background

With the development of the automobile industry and the gradual maturity of the stamping process, the shape of a finished part is more and more complex, the precision requirement is continuously improved, and meanwhile, in view of the increase of cost pressure, in order to save cost for enterprises, the flanging part of the part saves cost by reducing working procedures and improving the product quality, so that the molding requirement of a die product cannot reach an ideal state. Therefore, a structure for simultaneously realizing punching and flanging needs to be researched.

SUMMERY OF THE UTILITY MODEL

To the above problem, the to-be-solved technical problem of the utility model is to provide a realize the turn-ups's of punching a hole mould structure simultaneously.

The utility model discloses a realize turn-ups's that punches a hole mould structure simultaneously, it contains cope match-plate pattern, lower bolster, drift fixing base, drift and die case, and fixed mounting has the drift fixing base on the cope match-plate pattern, and the drift is installed to the front end of drift fixing base, and die case top surface middle part bulge's shape cooperatees with the shape of the periphery bulge of drift bottom, and die case installation fixes on the lower bolster.

Preferably, the punch is divided into an upper punch and a lower punch, and the diameter of the upper punch is 3-5mm larger than that of the lower punch.

Preferably, the punch is a heavy-duty punch with a height of 90 mm.

Preferably, the length of the punch passing through the flanging of the part is 0.5mm, and a clearance distance of 1.0mm is reserved between the front end of the punch and the die case.

Compared with the prior art, the beneficial effects of the utility model are that: by using the structure, the punching of the product can be realized, the flanging function of the product can also be realized, the manufacturing cost of the die can be saved, and the precision requirement of a workpiece can be ensured. The tension of the die structure can be relieved, and the working efficiency and the time cost are greatly improved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the following technical solutions are adopted in the present embodiment: the punching die comprises an upper die plate a, a lower die plate b, a punching head fixing seat 1, a punching head 2 and a die case 3, wherein the punching head fixing seat 1 is fixedly installed on the upper die plate a, the punching head 2 is installed at the front end of the punching head fixing seat 1, the punching head 2 is divided into the upper punching head 2-1 and the lower punching head 2-2, the diameter of the upper punching head 2-1 is 3-5mm larger than that of the lower punching head 2-2, the shape of the middle protruding part of the top surface of the die case 3 is matched with that of the outer circumference protruding part at the bottom of the punching head 2, the die case 3 is installed and fixed on the lower die plate b, the punching head is a heavy-load punching head with the height of 90mm, the flanging length of the punching head 2 passing through a part is 0.5mm, and the gap distance of 1.0.

When the part flanging and punching machine works, a part c needing flanging and punching is placed in the female die sleeve 3, the punching machine is started to drive the punch 2 to press downwards, the lower punch 2-2 punches the part c, the punching machine continues to press downwards after punching is finished, and the upper punch 2-1 can realize the flanging function on the part c because the size of the upper punch 2-1 is slightly larger than that of the lower punch 2-2.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
