Abstract

The utility model relates to technical field of mold, the mold of punching noise can be reduced more particularly to one kind, including upper mold, lower die, it is held in upper mold and is pierced by the cutter of upper mold bottom face and is provided with the dumping pit of lower die, cutter is to be obliquely installed and form oblique cut towards the end face of lower die, the left end point of oblique cut is the right endpoint of oblique cut from 5 times of the distance between upper mold bottom face from the distance between upper mold bottom face, by the way that the end face of cutter is arranged to tilt and forms oblique cut, and then left end and the right end formation height cutting edge of oblique cut, during punching, nibbling shear will be punched strength and reduce, and then achieve the effect that noise-decreasing.

Description

A kind of mold reducing punching noise

Technical field

The utility model relates to technical field of mold, and in particular to one kind can reduce the mold of punching noise.

Background technique

Stamping die is equipped a kind of special process that material is processed into part, referred to as cold punching in Cold Press Working Compression mould.Punching press, be at room temperature, using the mold being mounted on press machine to material apply pressure, make its generate separation or Plastic deformation, thus a kind of pressure processing method of part needed for obtaining.

Currently, being greater than the steelplate punching of 8mm for thickness, due to deburring blanking pressure and material shearing strength and material thickness Proportional relationship, and high strength steel plate material shearing strength is big, therefore is directed to high strength steel plate or heavy-gauge sheeting, the meeting in blanking process Very big noise is generated, this noise can also cause to hurt other than it can impact working environment to the body of operator Evil.

Utility model content

The purpose of this utility model is that aiming at the shortcomings in the prior art, and a kind of mould that punching noise is less is provided Tool.

The purpose of this utility model is achieved through the following technical solutions: one kind can reduce the mold of punching noise, including upper Mould, lower die are held in upper mold and are pierced by the cutter of upper mold bottom face and are provided with the dumping pit of lower die, and cutter is towards the end of lower die Face is to be obliquely installed and formed oblique cut, and the left end point of oblique cut is oblique cut from the distance between upper mold bottom face 5 times of right endpoint from the distance between upper mold bottom face.

Wherein, cutter includes first to rush block and second and rush block, and first, which rushes block, rushes block court towards the end face of lower die and second It is obliquely installed to the end face of lower die.

Wherein, first to rush the inclined direction that block rushes block towards the end face of lower die towards the end face of lower die and second opposite.

Wherein, elastic component is provided between cutter and upper mold.

Wherein, elastic component is ebonite block.

Wherein, upper mold is from top to bottom successively removably installed and is provided with upper die holder, cope plate and stripper plate.

Wherein, the cross section t shape setting of cutter.

The utility model has the beneficial effects that the mold for reducing punching noise of the application, by by the end face (work of cutter Make face) it is arranged to tilt and formed oblique cut, and then the left end of oblique cut and right end form height cutting edge, in punching In the process, nibbling shear will be punched strength and reduce, and then achieve the effect that noise-decreasing.

Detailed description of the invention

Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached Figure obtains other attached drawings.

Fig. 1 is the structural schematic diagram of the upper mold for the mold that one of the utility model can reduce punching noise.

Fig. 2 is the cross-sectional view of the upper mold for the mold that one of the utility model can reduce punching noise.

Fig. 3 is the enlarged drawing in Fig. 2 at C.

Detailed description of the invention: upper mold 1, upper die holder 11, cope plate 12, stripper plate 13, cutter 2, first rush block 21, second rush block 22, ebonite block 3.

Specific embodiment

The utility model is further described with the following Examples.

One kind of the utility model can reduce the specific embodiment of the mold of punching noise, as shown in Figure 1 to Figure 3, mould Tool includes upper mold 1, lower die, is held in upper mold 1 and is pierced by the cutter of 1 bottom face of upper mold and is provided with the dumping pit of lower die.Specifically , upper mold 1, which is from top to bottom successively removably installed, is provided with upper die holder 11, cope plate 12 and stripper plate 13.

It is that cutter is to be obliquely installed and form oblique cut towards the end face of lower die as improved, it should be noted that The top in figure in Fig. 2 or Fig. 3 is the bottom face of upper mold, i.e., direction shown in figure is contrary with upper mold actual installation, See Fig. 3, from the distance between 1 bottom face of upper mold (stripper plate 13), (Fig. 3 length a) is oblique cut to the left end point of oblique cut Right endpoint from the distance between 1 bottom face of upper mold (stripper plate 13), (5 times of Fig. 3 length b), compared with prior art, pass through The end face (working face) of cutter is arranged to tilt and formed oblique cut, and then the left end of oblique cut and right end form height Cutting edge, during punching, nibbling shear will be punched strength and reduce, and then achieve the effect that noise-decreasing.

It is when mold needs to steel plate while being punched two stations, to further decrease as further improved The punching direction of two stations or position can be reversed by the noise of punching, specifically, cutter includes first to rush block 21 Block 22 is rushed with second, first, which rushes block 21, rushes block 22 towards the end face of lower die and second and be obliquely installed towards the end face of lower die.Its In, first rush block 21 towards the end face of lower die and second rush block 22 towards the end face of lower die inclined direction on the contrary, further Bath noise is rushed in reduction.

Bath noise is rushed in order to further reduce, is provided with elastic component between cutter and upper mold 1, wherein elastic component is hard Blob of viscose 3.

Bath noise is rushed in order to further reduce, improves the structural strength of cutter, enhances the firmness of mold entirety, knife The cross section t shape of tool is arranged.

Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this The spirit and scope of utility model technical solution.
