Abstract

The utility model relates to a kind of edge of a knife anti-tripping waste mould, comprises die ontology, die ontology is provided with the edge of a knife for stamping-out processed product, and knife-edge is provided with multiple arc-shaped breach; Knife-edge is provided with multiple arc-shaped breach; arc-shaped breach circular arc defines according to stamping-out material thickness T radius of a circle R and depth H, and the waste material produced in product blanking process sticks in arc-shaped breach, thus prevents the situation of jump-scrap; improve yield rate, protect mould.

Description

A kind of edge of a knife anti-tripping waste mould
Technical field
The utility model relates to hardware dies field, more particularly, relates to a kind of edge of a knife anti-tripping waste mould.
Background technology
Drift (punch) and the edge of a knife (die): existing punching die because of punching too little, drift cannot process thimble top waste material, so the waste material produced during stamping-out easily daps, causes finished product rate low, and easy mold damage.
Utility model content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of edge of a knife anti-tripping waste mould.
The utility model solves the technical scheme that its technical problem adopts:
Construct a kind of edge of a knife anti-tripping waste mould, wherein, comprise die ontology, described die ontology is provided with the edge of a knife for stamping-out processed product, described knife-edge is provided with multiple arc-shaped breach.
Edge of a knife anti-tripping waste mould described in the utility model, wherein, described arc-shaped breach circular arc institute to radius of a circle R and circular arc depth H according to treating that stamping-out material thickness T defines: T=0.3-0.5mm, R=0.4mm, H=0.03mm; T=0.6-1mm, R=0.5mm, H=0.04mm.
Edge of a knife anti-tripping waste mould described in the utility model, wherein, described arc-shaped breach is evenly distributed on described knife-edge.
Edge of a knife anti-tripping waste mould described in the utility model, wherein, described arc-shaped breach is at least three.
Edge of a knife anti-tripping waste mould described in the utility model, wherein, described arc-shaped breach adopts linear cutter to make
The beneficial effects of the utility model are: knife-edge is provided with multiple arc-shaped breach; arc-shaped breach circular arc defines according to stamping-out material thickness T radius of a circle R and depth H; the waste material produced in product blanking process sticks in arc-shaped breach; thus prevent the situation of jump-scrap; improve yield rate, protect mould.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the edge of a knife anti-tripping waste edge of a knife cross-sectional structure schematic diagram of the utility model preferred embodiment;
Fig. 2 is the edge of a knife anti-tripping waste edge of a knife arc-shaped gap structure schematic diagram of the utility model preferred embodiment.
Detailed description of the invention
The utility model preferred embodiment as shown in Figure 1, consults Fig. 2 simultaneously, comprises die ontology 1, die ontology 1 is provided with the edge of a knife 2 for stamping-out processed product, and the edge of a knife 2 edge is provided with multiple arc-shaped breach 3; The edge of a knife 2 edge is provided with multiple arc-shaped breach 3; arc-shaped breach 3 circular arc defines according to stamping-out material thickness T radius of a circle R and depth H; the waste material produced in product blanking process sticks in arc-shaped breach 3; thus prevent the situation of jump-scrap; improve yield rate, protect mould.
As shown in Figure 2, arc-shaped breach 3 circular arc defines according to stamping-out material thickness T radius of a circle R and circular arc depth H: T=0.3-0.5mm, R=0.4mm, H=0.03mm; T=0.6-1mm, R=0.5mm, H=0.04mm, arrange roundlet arcuation breach 3, ensure that the precision of finished product while ensureing to stick into waste material in product blanking process.
As shown in Figure 2, arc-shaped breach 3 is evenly distributed on the edge of a knife 2 edge, ensure that the stability of blanking process while realizing preventing jump-scrap object in blanking process.
As shown in Figure 2, arc-shaped breach 3 is at least three, arranges multiple arc-shaped breach 3 and more effectively can guarantee that waste material sticks into arc-shaped breach 3 in blanking process, thus reach the object preventing jump-scrap, ensures production efficiency.
As shown in Figure 2, arc-shaped breach 3 adopts linear cutter to make, and using line to cut processing and makes arc-shaped breach 3 more smooth, avoiding because there is uneven phenomena impair mould production stability.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
