Abstract
The invention discloses an anti-rotation piercing punch which comprises a punching end and a fixed end, wherein the fixed end is fixed with a punch retainer; a blade is arranged on the edge at the lower end part of the punching end; an anti-rotation limited block is arranged at the tail end of the fixed end; the section of the anti-rotation limited block is hexagonal; the minimum diameter of the anti-rotation limited block is larger than the diameter of the fixed end; a groove is formed in a part close to the anti-rotation limited block at the fixed end; and a rubber ring is mounted in the groove. The anti-rotation piercing punch is simple in structure, is convenient to mount, and effectively solves the problem that the anti-rotation piercing punch is prone to rotate in operation.
Description
Technical field
The invention belongs to Stamping Die Technology field, especially relate to a kind of piercing punch of anti-rotation.
Background technology
At present in diel, piercing punch often adopts screw and baroclinic block etc. to be fastened on punch retainer, more monolateral limited impression, also alignment pin is had to locate, but these modes are located stable all not, and cause punch structure asymmetric, easily there is the phenomenons such as fracture during punch work, be therefore necessary that research and development are a kind of and effectively prevent Compression Stability and the effective piercing punch of anti-rotation.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: the piercing punch proposing a kind of anti-rotation.
Technical solution of the present invention is achieved in that a kind of piercing punch of anti-rotation, the stiff end comprising punching press end and fix with punch retainer; The edge, bottom of described punching press end has blade; The tail end of described stiff end is provided with an anti-rotation limited block; Described anti-rotation limited block cross section is hexagon; The minimum diameter of described anti-rotation limited block is greater than the diameter of stiff end.
Preferably, described stiff end is provided with groove near anti-rotation limited block place, is provided with rubber ring in described groove.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Piercing punch of the present invention, structure is simple, reasonable in design, hexagon anti-rotation limited block on stiff end, carried out hexagon location to punch, efficiently solved the problem that piercing punch operationally easily rotates, stiff end is near the groove design at anti-rotation limited block place, enhance the frictional force between the stiff end of punch and punch retainer, when further preventing punch from working, occur rotation phenomenon.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of piercing punch of the present invention.
Accompanying drawing 2 is the top view of piercing punch of the present invention.
Wherein: 1, punching press end; 2, stiff end; 3, anti-rotation limited block; 4, groove; 5, rubber ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
The piercing punch of anti-rotation of the present invention, the stiff end 2 comprising punching press end 1 and fix with punch retainer; The tail end of described stiff end 2 is provided with an anti-rotation limited block 3; Described anti-rotation limited block 3 cross section is hexagon; The minimum diameter of described anti-rotation limited block 3 is greater than the diameter of stiff end 2.Piercing punch of the present invention, structure is simple, and reasonable in design, the hexagon anti-rotation limited block on stiff end, has carried out hexagon location to punch, efficiently solved the problem that piercing punch operationally easily rotates.
Further instruction, described stiff end 2 is provided with groove 4 near anti-rotation limited block 3 place, is provided with rubber ring 5, enhances the frictional force between the stiff end of punch and punch retainer, occur rotation phenomenon when further preventing punch from working in described groove 4.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
