Abstract

The utility model discloses a kind of punching press anti-deformation molds, it includes upper die and lower die, there is locating slot compatible with disc sheet form, the bottom surface of locating slot is equipped with the first convex hull forming groove, the second convex hull forming groove, third convex hull forming groove and the 4th convex hull forming groove for being stamped and formed out convex closure on the upper surface of lower die.Using the above structure, the first convex closure, the second convex closure, third convex closure and the 4th convex closure can be stamped and formed out on disk, four specific shapes of convex closure realize reasonable Arrangement on disk, the integral strength of disk improved, so as to prevent disk from deforming.

Description

A kind of punching press anti-deformation mold

Technical field

The utility model relates to stamping die technology more particularly to a kind of punching press anti-deformation molds.

Background technique

In the prior art, disc sheet material is after punch forming, and due to its thinner thickness, change is easy to produce in use process Shape, therefore be badly in need of designing mold of a set of raising disc sheet strength to prevent deformation.

Summary of the invention

The purpose of this utility model is to provide the punching press anti-deformation moulds that one kind can significantly improve disc sheet strength Tool.

To achieve the above object, the utility model uses following technical scheme:

A kind of punching press anti-deformation mold, including upper die and lower die, have on the upper surface of the lower die and disc sheet material The compatible locating slot of shape, the bottom surface of locating slot are equipped with the first convex hull forming groove for being stamped and formed out convex closure, second convex It is bundled into type groove, third convex hull forming groove and the 4th convex hull forming groove, the first convex hull forming groove and the second convex hull forming groove are set respectively At the both ends of locating slot, third convex hull forming groove and the 4th convex hull forming groove interval are located at the middle part of locating slot, and described first is convex Type groove is bundled into convex, the two sides of the first convex hull forming groove long side are respectively equipped with curved portion；Second convex hull forming groove In convex, the both ends of the second convex hull forming groove long side are respectively equipped with L-type portion, and inverted T shaped space is formed between two L-type portions, described The long side of the long side of first convex hull forming groove and the second convex hull forming groove is respectively facing positioning groove center and is oppositely arranged；The upper mold Corresponding first convex hull forming groove in upper surface, the second convex hull forming groove, third convex hull forming groove and the 4th convex hull forming groove difference Equipped with the first convex closure forming punching head, the second convex closure forming punching head, third convex closure forming punching head and the 4th convex closure forming punching head.

The third convex hull forming groove and the 4th convex hull forming groove are strip.

First convex hull forming groove, the second convex hull forming groove, third convex hull forming groove and the 4th convex hull forming groove it is outer Periphery is equipped with radius.

The positioning column of taper is respectively equipped in two L-type portions.

The utility model uses above technical scheme, and the first convex closure, the second convex closure, third convex closure are stamped and formed out on disk With the 4th convex closure, four specific shapes of convex closure realize reasonable Arrangement on disk, improve the integral strength of disk, so as to Enough prevent disk from deforming.

Detailed description of the invention

The utility model is described in further details below in conjunction with the drawings and specific embodiments:

Fig. 1 is the schematic diagram of the utility model；

Fig. 2 is the top view of lower die.

Specific embodiment

As shown in Figure 1 or 2, the utility model includes upper mold 1 and lower die 2, is had and circle on the upper surface of the lower die 2 The compatible locating slot 21 of dish type sheet form, the bottom surface of locating slot 21 be equipped with the first convex closure for being stamped and formed out convex closure at Type groove 22, the second convex hull forming groove 23, third convex hull forming groove 24 and the 4th convex hull forming groove 25,22 He of the first convex hull forming groove Second convex hull forming groove 23 is respectively provided at the both ends of locating slot 21, third convex hull forming groove 24 and the 4th convex hull forming groove 25 interval It is located at the middle part of locating slot 21, first convex hull forming groove 22 is in convex, the two sides point of 22 long side of the first convex hull forming groove It She You not curved portion 221；Second convex hull forming groove 23 is also in convex, and the both ends of 23 long side of the second convex hull forming groove are distinguished Equipped with L-type portion 231, inverted T shaped space, the long side and the second convex closure of first convex hull forming groove 22 are formed between two L-type portions 231 The long side of forming tank 23 is respectively facing 21 center of locating slot and is oppositely arranged；The corresponding first convex closure molding in the upper surface of the upper mold 1 Slot 22, the second convex hull forming groove 23, third convex hull forming groove 24 and the 4th convex hull forming groove 25 are respectively equipped with the molding of the first convex closure Formed punch, the second convex closure forming punching head, third convex closure forming punching head and the 4th convex closure forming punching head.

The third convex hull forming groove 24 and the 4th convex hull forming groove 25 are strip.

First convex hull forming groove 22, the second convex hull forming groove 23, third convex hull forming groove 24 and the molding of the 4th convex closure The outer periphery of slot 25 is equipped with radius.It designs in this way, can make the outer edge for the convex closure gone out that there is rounded corner, avoid stress It concentrates and leads to convex closure edge break.

The positioning column of taper is respectively equipped in two L-type portions 231.Disc sheet material is positioned by positioning column, is prevented Disc sheet material is displaced in punching course, therefore stamping quality is higher.

Before punching press, disc sheet material is placed in locating slot 21, will form the first convex closure, second convex after punching press, on disk Packet, third convex closure and the 4th convex closure, four specific shapes of convex closure realize reasonable Arrangement on disk, improve the entirety of disk Intensity, so as to prevent disk from deforming.
