Abstract
The utility model relates to a die edge of a knife, especially waste material resilient mounting is prevented to die edge of a knife, including establishing the protruding muscle on the edge of a knife medial surface of die, protruding muscle is inboard protruding to the edge of a knife, the top of protruding muscle is equipped with the blanking inclined plane. Protruding muscle bottom is equipped with the guide inclined plane. The utility model provides a waste material resilient mounting is prevented to die edge of a knife overcomes the not enough of current structure, changes the die -cut face of original through type edge of a knife, and simple structure is stable, and the effectual waste back to jump that prevents has avoided that the product weighs wounded, a series of losses of mould damage etc. And then has improved the punching press speed of mould.
Description
Technical field
This utility model is related to a kind of die edge of a knife, especially the anti-scraps springing back device of the die edge of a knife.
Background technology
Mould is described as the mother of industry, and automobile industry is the Typical Representative of industrial development again, with automobile at a high speed, relax
The suitable, development of safe, body structure will be increasingly sophisticated, it is desirable to which mould develops to maximization, complication, high-precision matter direction, right
Product appearance and die life and production efficiency require more and more higher.But during punching production, waste material during punching
Often be bonded to mould or waste material jumped out to die knife edge surfaces, when causing punching press Jing often occur product weigh wounded or
It is burn failure, causes unnecessary loss.
Utility model content
To solve the above problems, this utility model provides a kind of die edge of a knife for preventing scraps springing back anti-scraps springing back dress
Put, concrete technical scheme is：
The anti-scraps springing back device of the die edge of a knife, including the convex tendon being located on the edge of a knife medial surface of die, the convex tendon is to knife
Mouth inner bulge, is provided with punching inclined-plane at the top of the convex tendon.
The convex tendon bottom is provided with guide inclined-plane.
The convex tendon is no less than one.
The convex tendon is no less than two, medial surface that is symmetrical or being distributed on the edge of a knife.
Punching inclined-plane is provided with the top of convex tendon, shape of product and drift is not affected.When drift is entered into inside the edge of a knife, punching
Head is not interfered with punching inclined-plane.Punching inclined-plane facilitates waste material to stick in convex tendon.The bottom on punching inclined-plane is not less than the top of waste material,
If waste material resilience upwards can be caused, it is impossible to play a part of to block waste material less than the top of waste material in the bottom on punching inclined-plane.
Guide inclined-plane facilitates the discharge of waste material, prevents from piling up excessive waste material impact punching.
It is good that the anti-jump effect of multiple convex tendons is set, it is especially symmetrical or uniform, waste material uniform force is made, effectively can be blocked useless
Material.
First by silk thread cutting processing of being careful during processing, convex tendon is shaped with the edge of a knife simultaneously, then convex tendon is processed again, is processed
Go out to be punched inclined-plane and guide inclined-plane.
During work, drift is descending is punched to tablet, and drift is entered inside the edge of a knife, produces waste material, now on the edge of a knife after punching
Convex tendon extrusional slug, makes waste material be stuck in the edge of a knife, without being bonded on drift, also will not leave as drift is up
Go out the edge of a knife.
The anti-scraps springing back device of the die edge of a knife that this utility model is provided overcomes the shortcomings of existing structure, changes original straight
The formula edge of a knife is punched face, simple and stable structure effectively prevents scrap-bounce, it is to avoid product is weighed wounded, the one of burn failure etc.
Series loss, and then improve the drawing velocity of mould.
Description of the drawings

Fig. 2 is the partial enlarged drawing in Fig. 1 at I；
Fig. 3 is sectional views of the Fig. 1 along line A-A.
Specific embodiment
In conjunction with description of the drawings specific embodiment of the present utility model.
As shown in Figure 1 to Figure 3, the anti-scraps springing back device of the die edge of a knife, including being located on 2 medial surface of the edge of a knife of die 1
Convex tendon 3.The convex tendon 3 is provided with punching inclined-plane 31 to 2 inner bulge of the edge of a knife, the top of the convex tendon 3, and bottom is provided with guide inclined-plane
32.The convex tendon is provided with three, is distributed on the medial surface of the edge of a knife 2.
During work, drift is descending is punched to tablet, and drift is entered inside the edge of a knife 2, produces waste material, now on the edge of a knife 2 after punching
3 extrusional slug of convex tendon, waste material is stuck in the edge of a knife 2, without being bonded on drift, also will not leave the edge of a knife as drift is up
The edge of a knife 2 is jumped out after 2.
