Abstract

The utility model discloses a kind of punching convex closure anti-tripping waste structures, it is successively arranged on the concave template and pre- rushes die hole, convex closure hole and punching and blanking die hole, and pre- die hole, convex closure hole and the punching and blanking die hole of rushing is arranged point-blank, the pre- die hole inner wall that rushes is special-shaped laciniation.The utility model structure is simple; change original punch-die shape and structure; it is easy to produce the blanking area of jump-scrap in a mold; design changes punching shape and is divided into two steps punching; step punching the phenomenon that causing waste material invert and rebound in cavity plate is avoided, enables the entrance cavity plate of product waste material stability regular, is played a very good protection to mold and product; the failure rate for reducing mold simultaneously improves the production capacity of punching production and the qualification rate of product to a certain extent.

Description

A kind of punching convex closure anti-tripping waste structure
Technical field
The utility model relates to a kind of punching convex closure anti-tripping waste structures, belong to mold manufacture field.
Background technique
Under the situation that auto parts and components are constantly updated, for the improvement in the design and practice of thin material product mold It is complementary, as long as the idea at design initial stage is to carry out conventional design according to technique stock layout to be punched qualified products. But produce irregular intermittent waste material in punching production process and jump out cavity plate phenomenon, slight jump-scrap may cause outside product It sees defect or product is unqualified, it is badly damaged that serious jump-scrap may cause die core component.
Utility model content
In order to solve in Dies ' Blanking convex closure product process, the regular shape blinking scrap of appearance jumps out showing for cavity plate As the utility model proposes a kind of punching convex closure anti-tripping waste structures, can reduce the failure rate of mold, mention to a certain extent The high production capacity of punching production and the qualification rate of product, improve processing efficiency.
The technical solution mainly used in the utility model are as follows:
A kind of punching convex closure anti-tripping waste structure is successively arranged on concave template and pre- rushes die hole, convex closure hole and punching and blanking die Hole, and pre- die hole, convex closure hole and the punching and blanking die hole of rushing is arranged point-blank, it is described pre- to rush die hole inner wall For special-shaped laciniation.
Preferably, it is described it is pre- rush die hole, convex closure hole and punching and blanking die hole it is equal there are two, be arranged in straight line On.
Preferably, the pre- die hole that rushes is less than punching and blanking die hole (i.e. product size).
The utility model has the advantages that the utility model provides a kind of punching convex closure anti-tripping waste structure, change original punch-die shape Structure is easy to produce the blanking area of jump-scrap in a mold, and design changes punching shape and is divided into two steps punching, avoids a step Punching the phenomenon that causing waste material invert and rebound in cavity plate, enable the entrance cavity plate of product waste material stability regular, to mould Tool and product play a very good protection, while reducing the failure rate of mold, improve punching production to a certain extent The qualification rate of production capacity and product.
Detailed description of the invention
Fig. 1 is that conventional one step of convex closure is punched schematic diagram;
Fig. 2 is to improve two step of convex closure anti-tripping waste in mold to be punched schematic diagram;
Fig. 3 is the improvement structure chart of the utility model;
In figure: rush in advance die hole 1, special-shaped laciniation 1-1, convex closure hole 2, punching and blanking die hole 3, rush in advance punch-pin 4-1, Convex closure punch-pin 4-2, blanking punch 4-3, briquetting 5, material strip 6, unloading block 7, convex closure cavity plate 8.
Specific embodiment
In order to make those skilled in the art better understand the technical solutions in the application, below to the embodiment of the present application In technical solution be clearly and completely described, it is clear that described embodiments are only a part of embodiments of the present application, Instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making creative labor Every other embodiment obtained under the premise of dynamic, shall fall within the protection scope of the present application.
Further detailed description has been done to the technical solution of the utility model with reference to the accompanying drawing:
As shown in Figure 1-3, a kind of punching convex closure anti-tripping waste structure, it is successively arranged on concave template and pre- rushes die hole 1, convex closure Hole 2 and punching and blanking die hole 3, and pre- die hole 1, convex closure hole 2 and the punching and blanking die hole 3 of rushing is arranged point-blank, Pre- 1 inner wall of die hole that rushes is special-shaped laciniation.
Preferably, it is described it is pre- rush die hole 1, convex closure hole 2 and punching and blanking die hole 3 there are two, be arranged in one On straight line.
Preferably, the pre- die hole 1 that rushes is less than punching and blanking die hole 3(i.e. product size).
As shown in Figure 1, carrying out convex closure using original punch-die shape and structure and being once punched, add in the same process convex closure Punching is completed together, without convex closure hole before punching, be easy to generate in punching production process irregular intermittent waste material jump out it is recessed Mould phenomenon.It,, will not in the state that product material hardness is harder even if punching product material thickness is thinning in the utility model The phenomenon that waste material jumps out punch-pin when generating punching easily.Improved structure can reduce the failure rate of mold, to a certain degree On can be improved punching production production capacity and product qualification rate.
As Figure 2-3, on the basis of original concave template, increase it is pre- rush die hole 1 and convex closure hole 2, to increase It is pre- to rush work step and convex closure work step, material strip 6 is placed on concave template, carries out pre- punching (pre-punched hole for the first time by rushing punch-pin 4-1 in advance Suitably less than product requirement size), and rush 1 inner wall of die hole in advance and be equipped with special-shaped zigzag fashion, it increases waste material and rushes in advance recessed The contact area of 1 inner wall of die hole enters waste material stabilization and rushes in die hole 1 in advance.Then the pre- punching of work step will be rushed in advance on material strip 6 Die hole 1 carries out convex closure work step at convex closure hole 2, which passes through 7 phase of convex closure punch-pin 4-2, convex closure cavity plate 8 and unloading block Mutually cooperation is completed.Secondary punching work step is carried out in punching and blanking die hole 3 by blanking punch 4-3 after the completion of convex closure, it is recessed due to rushing in advance Die hole 1 is irregular shape, i.e., rushes 1 inner wall abnormal shape zigzag of die hole in advance, so waste material gravity station when being punched for second is not In center, waste material is uneven, leads to waste material gravimetric tilt.To make waste material when secondary punching smoothly from punching and blanking die hole 3 lower section discharges, the phenomenon that will not generating jump-scrap, is to complete the punching press of qualified size.Fig. 3 is the die improvement of the utility model Molding convex closure is compressed with briquetting 5, is then punched again by structure chart, secondary punching work step.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
