Abstract
The present invention relates to a kind of blanking die with elasticity transition layer and preparation method thereof, including die holder, dynamic model and the cover half being arranged on die holder, between described cover half and die holder, be provided with at least one of which scale copper.The thickness of described copper sheet is 0.1mm.Described copper sheet is pyrite or red copper.This apparatus structure is simple, and the shear stress being prevented effectively from the punch press process stress in the same time is concentrated, and vibration source is greatly reduced, greatly reduces the generation of operating noise.
Description
Technical field
The present invention relates to a kind of blanking die with elasticity transition layer and preparation method thereof.
Background technology
In sheet metal stretching produces, particularly when punch press process, the punch and matrix of mould must be to be assemblied in steel die holder
Upper converted products, and with both screw tensions, be allowed to formation and be rigidly connected.Necessarily vibrate big time the most die-cut during metallic article,
Produced noise is big, and mould even can be caused to burst apart.
Summary of the invention
The problem that the present invention is directed to the existence of above-mentioned prior art makes improvement, i.e. the technical problem to be solved is
Thering is provided a kind of blanking die with elasticity transition layer and preparation method thereof, the shear stress being prevented effectively from punch press process is same
The stress of one time is concentrated, and vibration source is greatly reduced, greatly reduces the generation of operating noise.
In order to solve above-mentioned technical problem, a kind of technical scheme of the present invention is: a kind of stamping-out with elasticity transition layer
Mould, including die holder, dynamic model and the cover half being arranged on die holder, is provided with the thin copper of at least one of which between described cover half and die holder
Sheet.
Further, the thickness of described copper sheet is 0.1mm.
Further, described copper sheet is pyrite or red copper.
Further, described copper sheet is 2 layers.
In order to solve above-mentioned technical problem, a kind of technical scheme of the present invention is: a kind of stamping-out with elasticity transition layer
The manufacture method of mould, including die holder, dynamic model and the cover half being arranged on die holder, is carried out: by the following method at die holder and cover half
Between least one layer of scale copper is set.
Further, the thickness of described copper sheet is 0.1mm.
Further, described copper sheet is pyrite or red copper.
Further, described copper sheet is 2 layers.
Compared with prior art, the method have the advantages that
1, the stress in the same time of the shear stress during this structure is prevented effectively from punch press process is concentrated, and vibration is greatly reduced
Source, greatly reduces the generation of operating noise；
2, this structure is the good embodiment in actual combat of the elasticity transition layer principle of noise reduction, and can prevent mould from bursting apart, practical function
Well；
2, loose contact between mold component is eliminated；
3, being rigidly connected of cover half and die holder is avoided；
4, punch press and mould are protected.
The present invention will be further described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the organigram of the embodiment of the present invention.
In figure: 1-dynamic model, 2-cover half, 21-punch, 22-die, 3-die holder, 4-copper sheet.
Detailed description of the invention
Embodiment one: as it is shown in figure 1, a kind of blanking die with elasticity transition layer, including die holder 3, dynamic model 1 and setting
Cover half 2 on die holder, is provided with two-layer latten(-tin) 4 between described cover half 2 and die holder 3.
In the present embodiment, the thickness of described latten(-tin) is 0.1mm.
Latten(-tin) is as elasticity transition layer, during dynamic model impacts downwards, has had buffering between cover half and die holder, from
And the stress that the shear stress being prevented effectively from punch press process is in the same time is concentrated, vibration source is greatly reduced, significantly drops
The low generation of operating noise, protects mould and punch press.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent with
Modify, all should belong to the covering scope of the present invention.
