Abstract
The present invention relates to the anti-scraps springing back device of a kind of cavity plate edge of a knife, especially the cavity plate edge of a knife, including the convex ribs being located on the edge of a knife medial surface of cavity plate, the convex ribs are equipped with punching inclined-plane to edge of a knife inner bulge, the top of the convex ribs.The convex ribs bottom is equipped with guide inclined-plane.The anti-scraps springing back device of the cavity plate edge of a knife provided by the invention overcomes the shortcomings of existing structure, change original through type edge of a knife punching face, simple and stable structure, effectively prevents scrap-bounce, avoid product weigh wounded, a series of losses of burn failure etc., and then improve the drawing velocity of mould.
Description
Technical field
The present invention relates to the anti-scraps springing back device of a kind of cavity plate edge of a knife, especially the cavity plate edge of a knife.
Background technology
Mould is known 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 higher and higher.But during punching production, waste material during punching
Upper mold either waste material is often bonded to jump out to cavity plate knife edge surfaces, cause often to occur during punching press product weigh wounded or
It is burn failure, causes unnecessary loss.
The content of the invention
To solve the above problems, the present invention provides a kind of anti-scraps springing back device of the cavity plate edge of a knife for preventing scraps springing back, tool
Body technique scheme is：
The anti-scraps springing back device of the cavity plate edge of a knife, including the convex ribs being located on the edge of a knife medial surface of cavity plate, the convex ribs are into the edge of a knife
Side is raised, and the top of the convex ribs is equipped with punching inclined-plane.
The convex ribs bottom is equipped with guide inclined-plane.
The convex ribs are no less than one.
The convex ribs are no less than two, medial surface that is symmetrical or being distributed on the edge of a knife.
The top of convex ribs is equipped with punching inclined-plane, does not influence shape of product and punch.When punch is entered inside the edge of a knife, punching
Head is not interfered with punching inclined-plane.Punching inclined-plane facilitates waste material to stick into convex ribs.The bottom for being punched inclined-plane is not less than the top of waste material,
If the bottom for being punched inclined-plane is less than the top of waste material, waste material can be caused to spring back upwards, it is impossible to play the role of blocking waste material.
Guide inclined-plane facilitates the discharge of waste material, prevents that accumulating excessive waste material influences punching.
Set the anti-jump effect of multiple convex ribs good, it is especially symmetrical or uniformly distributed, make waste material uniform force, can effectively block useless
Material.
First shaped with the edge of a knife by silk thread cutting processing of being careful, convex ribs during processing, convex ribs are processed again at the same time then, processed
Go out to be punched inclined-plane and guide inclined-plane.
Punch downlink is punched tablet during work, and punch enters inside the edge of a knife, waste material is produced after punching, at this time on the edge of a knife
Convex ribs extrusional slug, makes waste material be stuck in the edge of a knife, without being sticked on punch, is jumped after the edge of a knife will not being left with punch uplink
Go out the edge of a knife.
The anti-scraps springing back device of the cavity plate edge of a knife provided by the invention overcomes the shortcomings of existing structure, changes original through type
The edge of a knife is punched face, and simple and stable structure, effectively prevents scrap-bounce, avoid product weigh wounded, burn failure etc. it is a series of
Loss, and then improve the drawing velocity of mould.
Brief description of the drawings
Fig. 1 is the top view of cavity plate；
Fig. 2 is the partial enlarged view at I in Fig. 1；
Fig. 3 is sectional views of the Fig. 1 along line A-A.
Embodiment
In conjunction with the embodiment of the brief description of the drawings present invention.
As shown in Figure 1 to Figure 3, the anti-scraps springing back device of the cavity plate edge of a knife, including be located on 2 medial surface of the edge of a knife of cavity plate 1
Convex ribs 3.The convex ribs 3 are equipped with punching inclined-plane 31 to 2 inner bulge of the edge of a knife, the top of the convex ribs 3, and bottom is equipped with guide inclined-plane
32.The convex ribs are equipped with three, are distributed on the medial surface of the edge of a knife 2.
Punch downlink is punched tablet during work, and punch enters inside the edge of a knife 2, waste material is produced after punching, at this time on the edge of a knife 2
3 extrusional slug of convex ribs, waste material is stuck in the edge of a knife 2, without being sticked on punch, the edge of a knife will not be left with punch uplink
The edge of a knife 2 is jumped out after 2.
