Abstract

The invention relates to a tool for punching a mould. The tool comprises a knife base, a knife blade and a knife edge, wherein the knife base is a lower mould core of the mould; the knife blade is fixedly arranged on the knife base; and the knife edge is fixedly arranged on the knife blade. Compared with the prior art, the tool for punching the mould has the advantages that the service life of the tool is greatly prolonged, the punching effect is good, and the like.

Description

A kind of cutter of die cutting die

Technical field

The present invention relates to a kind of cutter, especially relate to a kind of cutter of die cutting die.

Background technology

The die cutting die of felt mainly is divided into two kinds of moulds at present, and a kind of is the male and female die cutting dies; A kind of is to chop mould, and the operation principle of male and female mould is: the semi-finished product felt part of forming is sheared; The operation principle of chopping mould is: thus making it to rupture through edge of a knife extruding felt material reaches the purpose that cuts the part leftover pieces.We are not difficult to find out that product periphery quality that die cutting die makes is better than and chop mould from operation principle; But see that from development cost and use cost and maintaining we find out easily that again chopping mould occupies absolute advantage than male and female are die-cut; Therefore by most enterprises and a lot of customer services approvals, present have good market prospects.

But chop mould at present individual shortcoming is arranged, that is exactly an edge of a knife rapid wear, therefore most mould enterprise; Adopt following two kinds of schemes to solve this problem, the one: like Fig. 1, shown in Figure 2, the edge of a knife partly uses mould steel (such as the SKD11 that inserts; SKD61, P20 etc.); The 2nd: like Fig. 3, shown in Figure 4, the whole mould steel that uses of mould die, all there is a common shortcoming in these two kinds of schemes, and that is exactly an expensive, and development cost is big.So in today this economic society and efficiency society, these two kinds of methods all exist economical and practical problem.

Summary of the invention

The object of the invention is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of cutter life increases greatly, the cutter of die-cut effective die cutting die.

The object of the invention can be realized through following technical scheme:

A kind of cutter of die cutting die is characterized in that, comprises cutter base, blade, the edge of a knife, and described cutter base is the following die of mould, and described blade is fixed on the cutter base, and the described edge of a knife is fixed on the blade.

The material of described blade is generally decided according to mould die material is different, and using always has H13, stainless steel etc.

The described edge of a knife adopts firm material.

Described blade is welded on the cutter base through electric welding.

The described edge of a knife is welded on the blade through electric welding or argon arc welding.

Compared with prior art, the present invention has the following advantages:

1, cutter life increases greatly, and is die-cut effective, and product periphery quality is good;

2, easy and simple to handle, with low cost, the construction cycle is short;

3, the scope of application is wide, and market prospects are good.

Description of drawings

The structural representation that Fig. 1 adopts mould steel to insert for existing cutter;

Fig. 2 is the A portion enlarged drawing of Fig. 1;

Fig. 3 is that existing cutter adopts the whole structural representation that uses mould steel of die;

Fig. 4 is the B portion enlarged drawing of Fig. 3.

Fig. 5 is a structural representation of the present invention;

Fig. 6 is the C portion enlarged drawing of Fig. 5.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is elaborated.

Embodiment

Like Fig. 5, shown in Figure 6, a kind of cutter of die cutting die comprises cutter base, blade 4, the edge of a knife 5, and described cutter base is the following die 2 of mould, and described blade 4 electric welding are deposited on the cutter base, and the described edge of a knife 5 electric welding (or argon arc welding) are deposited on the blade 4.

Die cutting die comprises upper cores 1, following die 2, cutter, and product 3 is located between upper cores 1, the following die 2.The work flow of cutter is following:

One, digital control processing, process tool are prolonged edge of a knife route conformal and are left a groove;

Two, electric welding or argon arc welding are burnt last layer and are connected material, i.e. blade in edge of a knife groove;

Three, argon arc welding is connecting burning last layer die steel material, the i.e. edge of a knife on the material;

Four, digital control processing mills out the edge of a knife.

The invention solves above two kinds of structures and chop the shortcoming of mould, this method also can be used for the part and the equipment of those local needs sclerosis simultaneously.

Claims

1. the cutter of a die cutting die is characterized in that, comprises cutter base, blade, the edge of a knife, and described cutter base is the following die of mould, and described blade is fixed on the cutter base, and the described edge of a knife is fixed on the blade.

2. the cutter of a kind of die cutting die according to claim 1 is characterized in that, the material of described blade is H13 or stainless steel.
