Abstract
The utility model discloses a kind of blanking structures of punching press grinding tool, it is big to solve existing punching press grinding tool punching product angle of collapsing, the problem of influencing product quality, including feeding punching and ejection block, the bottom surface of the feeding punching offers circular concave, the circular concave and feeding punching are coaxially disposed, the top surface of the ejection block is equipped with rounded convex, the circular concave is corresponding up and down with rounded convex, and rounded convex can be embedded in circular concave, it is connected wall between the bottom surface that the circular concave is rushed with feeding, and the wall that is connected between rounded convex and the top surface of ejection block is to be obliquely installed, the utility model reduces the angle of collapsing of punching product, improve the quality of product.
Description
Technical field
The utility model relates to a kind of blanking structures of punching press grinding tool.
Background technique
Stamping die is to carry out the equipment that pressure processing uses to material, its working principle is that passing through mold in the work of punching press
The raw material between it are cut with the folding of lower drive upper mold and lower die, punching, stretching etc. are shaped to form stamping parts.
In the prior art, when being punched to raw material, product can generate larger for the feeding punching in upper mold and the ejection block in lower die
Angle of collapsing, influence the quality of product.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of blanking structure of punching press grinding tool, reduces punching and produces
The angle of collapsing of product, improves the quality of product.
To achieve the above object, the utility model provides following technical solution:
A kind of blanking structure of punching press grinding tool, including feeding punching and ejection block, it is recessed that the bottom surface of the feeding punching offers circle
Face, the circular concave and feeding punching are coaxially disposed, and the top surface of the ejection block is equipped with rounded convex, on the circular concave and rounded convex
Lower correspondence, and rounded convex can be embedded in circular concave.
Preferably, the top surface for being connected wall and rounded convex and ejection block between bottom surface that the circular concave is rushed with feeding
Between linking wall be to be obliquely installed.
Compared with the existing technology, the advantages of the utility model are as follows: feeding rushes to circle in the setting and ejection block of circular concave
When being punched to raw material, the portion of product is extruded into circular concave for the setting on convex surface, in this case the angle of collapsing of product
Angle of collapsing can significantly reduce, and grind convenient for the later period, and removal is collapsed angle.
Detailed description of the invention
Fig. 1 is the schematic diagram of the blanking structure of punching press grinding tool provided by the present embodiment；
Fig. 2 is the portion A enlarged drawing in Fig. 1.
Specific embodiment
It is further described by blanking structure of the Fig. 1 to Fig. 2 to the utility model punching press grinding tool.
The bottom surface of a kind of blanking structure of punching press grinding tool, including feeding punching 1 and ejection block 2, the feeding punching 1 offers circle
Concave surface 3, the circular concave 3 and 1 coaxial arrangement of feeding punching, the top surface of the ejection block 2 are equipped with rounded convex 4, the circular concave 3 with
About 4 rounded convex is corresponding, and rounded convex 4 can be embedded in circular concave 3.
Further, it is connected wall and rounded convex 4 and ejection block 2 between the circular concave 3 and the bottom surface of feeding punching 1
Top surface between linking wall be to be obliquely installed, the setting is convenient for extruding to product 5, so that product 5 is effectively squeezed into
Into circular concave 3, supplying for material is realized.
Further, the feeding punching 1 includes material punching 1 and material punching 2 12, and the material punching 2 12 is removably connected to material
One 11 lower end is rushed, the circular concave 3 is located at the lower end surface of material punching 2 12；The ejection block 2 includes block 1 and block 2 21, institute
The upper surface that block 2 21 is removably connected to block 1 is stated, the rounded convex 4 is located at the top surface of block 2 21, can basis under the setting
Different material is thick, replaces to material punching 2 12 and block two, that is, replacing with has and the thick compatible round recessed of material and boss
The material punching 2 12 in face 4 and block two improve the flexibility that the utility model uses.
Further, the material punching 1 is bolted with material punching 2 12 and block one and block two, i.e. material punching one
11 and material punching 2 12 on offer the threaded hole extended up and down, bolt is arranged in simultaneously in two threaded holes, realize material rush one
11 and material punching 2 12 be spirally connected, be similarly also equipped with the threaded hole extended up and down on block one and block two, bolt is arranged in two simultaneously
In a threaded hole, which realizes being detachably connected for material punching 1 and material punching 2 12 and block one and block two.
It should be noted that for ease of description, the noun of locality that the present embodiment is used, only with reference to Figure of description, with this
Embodiment is actual unrelated with orientation.
The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to
Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
