Description
Technical field
It the utility model is related to handware stamping area, and in particular to a kind of new handware punching structure.
Background technology
Stamping die, is in Cold Press Working, by material（Metal is nonmetallic）It is processed into part（Or semi-finished product）'s
A kind of special process equipment, is known as cold punching die（It is commonly called as cold-punching mould）.Punching press, is at room temperature, using installed in forcing press
On mould pressure is applied to material, it is produced separation or plastic deformation, so that a kind of pressure processing of part needed for obtaining
Method.
It is in the majority with handware stamping die in stamping die, can by punching press since metal has good ductility
It is produced plastic deformation, also because metal has ductility, when punching press separates, the metal of incision can not be avoided to produce modeling
Property deformation.Deformation extent outside during handware punching press is greater than inside, and metal is influenced to be pulled to incision be subject to impulse force, this is just
It is that handware outer surface produces friction with stamping die, easily damages color handware outer surface.Existing stamping die is to use
Simple punch coordinates what is be punched out with stamped groove, and the no good inhibiting effect of deformation to handware surface, does not have yet
Good protective effect, this is resulted in, and handware Pressing Deformation is unstable, and surface easily scratches.Handware more small deformation is more obvious,
Handware surface is difficult to reach high-precision requirement, the handware for having bulge-structure for surface, its punching press difficulty bigger.
Utility model content
The utility model aim is to provide a kind of new handware punching structure, it can efficiently solve institute in background technology
There are the problem of.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of new handware punching structure, including matrix, described matrix bottom outside are provided with briquetting, structure between briquetting
Into avoiding hollow groove, the briquetting bottom is provided with elastic compression layer, and the elastic compression layer is multiple cushions in briquetting bottom surface structure
Granulate distribution, and described matrix bottom inside is provided with guide groove, and matched punch, the punch are provided with the guide groove
Bottom is provided with cutting edge, and the driving cylinder that driving punch carries out punching press is provided with described matrix.
Matrix is fallen during punching press, handware periphery is compressed by briquetting, suppresses deformation during handware surface punching press,
Handware is compressed at the same time, prevents handware from moving；Cushion be distributed in pelletized form can greatly enhance briquetting and handware it
Between pressure, handware surface formed multiple spot thrust, handware areal deformation is interfered, preferably protects handware
Surface, reaches more preferable punching precision；The setting of avoiding hollow groove can accommodate the bulge-structure of handware, prevent from interfering.
Further, the cushion is column, and cushion upper end is stretched into inside briquetting, and cushion lower end is in briquetting bottom surface
Form granular distribution.
Cushion is column and stretches into inside briquetting, can strengthen the compactness that cushion is connected with briquetting.
Further, the cross section of the cushion is oval, and oval major radius stretches to cutting edge.
Handware Pressing Deformation is more serious closer to incision deformation, and the cross section of cushion is set as ellipse,
And notch is stretched at long end, larger frictional force is produced with handware surface during punching press, and fastening effect is more preferable.
Further, the cushion bottom surface is provided with compression line, and the compression line is the multiple and cross section of cushion
Concentric annular projection.
Compression line is set to strengthen the pressure between cushion and handware again, the support of concentric annular protrusion is able to ensure that
Cushion uniform force, produces handware stable pressuring action.
Further, the annular projection is oval and major radius direction is identical with the cross section of cushion.
Notch is stretched at the long end of annular protrusion, it is possible to increase frictional force, further reinforcement cushion are bonded with handware.
The beneficial effects of the utility model are：
The utility model sets the elastic compression layer of granular distribution to compress handware, it is ensured that handware is in punching press
Multiple spot thrust is formed on its surface, handware surface is compressed and deformation is interfered, preferably protects handware
Surface, reaches more preferable punching precision.

Embodiment
In order to make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1-Figure 3, a kind of new handware punching structure, including matrix 1,1 bottom outside of described matrix are set
There is briquetting 2, form avoiding hollow groove 3 between briquetting 2,2 bottom of briquetting is provided with elastic compression layer 4, and the elastic compression layer 4 is
Multiple cushions 5 form granular distribution in 2 bottom surface of briquetting, and 1 bottom inside of described matrix is provided with guide groove 6, is set in the guide groove 6
Be equipped with matched punch 7,7 bottom of punch is provided with cutting edge 8, be provided with described matrix 1 driving punch 7 into
The driving cylinder 9 of row punching press.
The cushion 5 is column, and 5 upper end of cushion is stretched into inside briquetting 2, and 5 lower end of cushion is formed in 2 bottom surface of briquetting
Granular distribution.
The cross section of the cushion 5 is oval, and oval major radius stretches to cutting edge 8.
5 bottom surface of cushion is provided with compression line, and the compression line is multiple rings concentric with the cross section of cushion 5
Shape protrusion 10.
The annular projection 10 is oval and major radius direction is identical with the cross section of cushion 5.
It is the wherein specific implementation of the utility model above, therefore its description is more specific and detailed, but can not be
And it is interpreted as the limitation to the utility model patent scope.It should be pointed out that for those of ordinary skill in the art,
Without departing from the concept of the premise utility, various modifications and improvements can be made, these obviously replace shape
Formula belongs to the scope of protection of the utility model.
