The utility model provides a be suitable for side cut drift of convex closure matrix product, be provided with the drift body that has the form edge of a knife of bending including one, be equipped with supplementary edging groove on the edge of a knife, the form of bending is the syllogic, the edging groove includes the middle section and sets up in the segmental arc of mending at middle section both ends, the segmental arc with rounding off between the middle section, and two the segmental arc is buckled to opposite direction respectively. The beneficial effects of the utility model are embodied in: through set up the trimming groove in the cutting edge department for the material in the region of waiting to cut edge of semi-manufactured goods extrudees supplementary trimming groove department down the in-process in the punching press, thereby forms and compresses tightly the material, and the material slides when not letting cut edge, reaches normal side cut purpose.

Description

Trimming punch head suitable for convex hull matrix product

Technical Field

The utility model belongs to the technical field of stamping forming, concretely relates to be suitable for side cut drift of convex closure matrix product.

Background

The stamping is a forming method in which a press and a die are used to apply external force to a plate, a strip, a pipe, a profile, etc. to cause plastic deformation or separation, thereby obtaining a workpiece (stamped part) of a desired shape and size. Products with different structures even aiming at different punched materials need to correspond to different punches, for example, for some stainless steel products with thickness below 0.2mm and convex hull matrixes, due to the fact that the thickness of the products is very thin, trimming aiming at a corner part close to 0 degree is difficult to achieve smoothly in the punching process, and the problems of continuous cutting, large burrs and the like usually occur by adopting the existing punches.

SUMMERY OF THE UTILITY MODEL

The utility model provides a be suitable for side cut drift of convex closure matrix product.

The purpose of the utility model is realized through the following technical scheme:

the trimming punch suitable for the convex hull matrix product comprises a punch body provided with a bent knife edge, wherein an auxiliary trimming groove is formed in the knife edge.

Preferably, the width of the auxiliary trimming groove is 0.5-1 mm.

Preferably, the punch body comprises an arc pressing surface attached to the surface of the convex hull of the product and an abutting surface arranged at an angle with the arc pressing surface, and the abutting surface is matched with a punching female die in a punching die.

Preferably, the bending shape is a three-section shape, the trimming groove comprises a middle section and arc sections arranged at two ends of the middle section, the arc sections are in smooth transition with the middle section, and the two arc sections are respectively bent in opposite directions.

The beneficial effects of the utility model are embodied in: through set up the trimming groove in the cutting edge department for the material in the region of waiting to cut edge of semi-manufactured goods extrudees supplementary trimming groove department down the in-process in the punching press, thereby forms and compresses tightly the material, and the material slides when not letting cut edge, reaches normal side cut purpose.

Detailed Description

The technical solution of the present invention is specifically described below with reference to the following examples.

With reference to fig. 1-3, the utility model discloses a be suitable for side cut drift of convex closure matrix product 11, including being provided with the drift body that has the form edge of a knife 3 of bending, the drift body include one with the arc laminating face 2 of 11 convex closure surfaces 13 laminating of product and with arc laminating face 2 is the butt face 1 of angle setting, butt face 1 need cooperate with the die-cut die cavity in the die-cut mould in actual punching press process. The bending shape is a three-section structure. The knife edge 3 is correspondingly provided with an auxiliary trimming groove 4, and the width of the auxiliary trimming groove is 0.5-1 mm. The trimming groove 4 comprises a middle section and arc sections arranged at two ends of the middle section, the arc sections are in smooth transition with the middle section, and the two arc sections are bent towards opposite directions respectively. The trimming groove 4 is matched with the part 12 to be punched of the product.

The utility model discloses stamping process is similar with prior art, treats the punching press product through the drift edge of a knife and carries out the pressfitting. Because the utility model discloses go up the setting in auxiliary tank, can utilize the material to have the characteristic of easily warping and kick-backing at the pressfitting in-process for the local characteristic of product is out of shape and is handled, extrudees it to supplementary trimming groove department and fixes a position, cuts edge with better, simultaneously, has also solved among the prior art and has cut constantly and cut edge burr big scheduling problem.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein, and any reference signs in the claims are not intended to be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
