Description

Blanking male die convenient to quick replacement

Technical Field

The utility model belongs to blanking mould and part field thereof, more specifically the blanking terrace die convenient to quick replacement that says so relates to.

Background

At present in automobile panel stamping die, contain the abnormal shape hole in a lot of plates, consequently the blanking terrace die also shape is different, contains the weak position of intensity in the blanking terrace die usually, the position that size or thickness are less promptly, and in blanking process, very easily damage need change whole terrace die after damaging. A large amount of material cost, processing cost and manpower debugging cost are generated, and further the use cost of the die is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a blanking terrace die convenient to quick replacement solves prior art, on the part blanking terrace die, because of containing the less or thin weak position of intensity of thickness of size, and leads to the problem of easy damage appearing, and need change whole terrace die after damaging, causes problem with high costs.

The technical scheme of the utility model is that the blanking male die convenient for quick replacement comprises a male die plate, a male die main body and a plurality of male die inserts which are arranged on the male die plate, wherein the male die main body and the plurality of male die inserts are spliced into a complete male die; the area of the male die insert is smaller than that of the male die body, and the male die insert is arranged on the outer side of the male die body.

Preferably, the male die body and the male die insert are respectively provided with a countersunk screw hole.

Preferably, a dovetail groove is formed in the connection part of the male die main body and the male die insert, and a dovetail joint matched with the dovetail groove is formed in the connection part of the male die insert and the male die main body.

Preferably, the dovetail slot and the dovetail are each radiused at the apex.

The utility model discloses technical scheme's a blanking terrace die convenient to quick replacement's beneficial effect is: the male die main body and the plurality of male die inserts are spliced into a complete male die, and after the weak part on the male die inserts is damaged, the corresponding male die inserts only need to be uniformly distributed and replaced, so that the material cost and the processing cost of the die are reduced, the use cost of the die in production is reduced, and the production efficiency of the die is improved.

Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention by those skilled in the art, the technical solutions of the present invention will now be further described with reference to the drawings attached to the specification.

In the stamping die for the automobile panel, a plurality of plate pieces contain special-shaped holes, so that the shape of a blanking male die is different, and the blanking male die usually contains a part with weak strength, namely a part with small size or thickness, and is extremely easy to damage in the blanking process. In the technical scheme, the integral punch is divided according to the structure of the punch, the part with weak strength is separated from the punch to serve as the punch insert 12, and the main body of the punch serves as the punch main body 11, so that after the part with weak strength which is easy to damage is damaged, namely the punch insert 12 is damaged, only the single punch insert 12 needs to be replaced, the punch main body 11 does not need to be replaced, and the use cost of the die is saved. Meanwhile, the punch insert 12 is partially replaced, so that the punch is convenient to position in size, quick replacement is realized, and the production and maintenance efficiency of the die is improved.

Based on the above technical scheme and technical idea, a specific structure of the blanking punch is described in detail below.

As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses technical scheme a blanking terrace die convenient to quick replacement, including 2 and install terrace die main part 11 and a plurality of terrace die insert 12 on 2 of terrace die board, terrace die main part 11 and a plurality of terrace die insert 12 splice into complete terrace die 1. The area of the punch insert 12 is smaller than that of the punch body 11, and the punch insert 12 is arranged on the outer side of the punch body 11. The part marked 10 on the punch insert 12 is a part with a small thickness and weak strength. At least one such weakness is present on a punch insert 12. During punching, the problems of breakage and the like are easy to occur. If the punch insert 12 is broken or damaged, only part of the punch insert 12 needs to be replaced, the punch body 11 with large area and thickness does not need to be replaced, and the punch body does not need to be disassembled and assembled, so that the cost is saved on one hand, and the quick positioning and installation of the punch insert 12 are facilitated on the other hand.

The punch body 11 and the punch insert 12 are respectively provided with a countersunk screw hole 13/14. The punch body 11 and the punch insert 12 are fixed to the punch plate 2 by a countersunk screw and a countersunk screw hole 13/14, respectively. A dovetail groove 15 is arranged at the joint of the punch body 11 and the punch insert 12, and a dovetail 16 matched with the dovetail groove 15 is arranged at the joint of the punch insert 12 and the punch body 11. The dovetail groove 15 and the dovetail 16 are spliced with each other, so that the male die insert 12 and the male die body 11 are spliced, and the male die insert 12 is convenient to position and mount quickly when replaced. The top corners of the dovetail groove 15 and the dovetail 16 are chamfered, so that the appearance of sharp top corners is avoided, the wear rate and the damage probability of the sharp top corners are reduced, and the service life of the blanking male die is prolonged.

The technical solution of the present invention is to provide an improved method for manufacturing a semiconductor device, which is characterized in that the method is not limited by the above-mentioned method, and the method is not substantially improved by the method and the device, or the method and the device are directly applied to other occasions without improvement, all within the protection scope of the present invention.
