Description
Technical field
The present invention relates to a kind of punching concave die cutting edge structure.
Background technology
The punched scrap rebound of high speed stamping can produce bad impression, or trigger folded to next on molding surface to stamping parts
Cutting edge accident is touched in piece punching press.The reason for punched scrap knock-ons is caused to have：Waste material is by oil film adhesion；Waste material is produced with punch-pin end face
Vacuum suction etc..
The content of the invention
The technical problem to be solved in the present invention is：Deficiency in the prior art is overcome to avoid punched scrap from returning there is provided one kind
The punching concave die cutting edge structure of jump.
The technical solution adopted for the present invention to solve the technical problems is：A kind of punching concave die cutting edge structure, including cavity plate
The cavity plate through hole through die body upper surface with die body lower surface is provided with body, die body, cavity plate through hole is justified including bottom discharge
Taper hole and cylindrical hole, cavity plate through hole also include the conical bore being arranged between cylindrical hole and die body upper surface, cylindrical hole two ends
The small bore end with both bottom discharge conical bore and conical bore is communicated respectively, and the depth of conical bore is 1mm, the circular cone drift angle of conical bore
For 1 °~2 °, the circular cone drift angle of bottom discharge conical bore is 4 °~6 °.
The beneficial effects of the invention are as follows：The present invention is provided with conical bore, shape after stamping is stamped in this place at cutting edge of die
Into the punched scrap more than cylinder bore diameter, after punched scrap is pushed further into cylindrical hole by drift, punched scrap and circle
Transition tight fit is formed between post holes, it is difficult to knock-on again to cause punched scrap, so as to solve the problems, such as the rebound of punched scrap.
Brief description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
In figure：1. die body；2. bottom discharge conical bore；3. cylindrical hole；4. conical bore.
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram, only with signal
Mode illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
It is provided with a kind of punching concave die cutting edge structure as shown in Figure 1, including die body 1, die body 1 and runs through die body 1
Upper surface and the cavity plate through hole of the lower surface of die body 1, cavity plate through hole include bottom discharge conical bore 2 and cylindrical hole 3, and cavity plate through hole is also
Including the conical bore 4 being arranged between cylindrical hole 3 and the upper surface of die body 1, the two ends of cylindrical hole 3 respectively with bottom discharge conical bore 2
Both small bore end is communicated with conical bore 4, and the depth of conical bore 4 is 1mm, the circular cone drift angle of conical bore 4 for 1 °~2 °, bottom discharge
The circular cone drift angle of conical bore 2 is 4 °~6 °.
The technical concepts and features of above-mentioned embodiment only to illustrate the invention, its object is to allow be familiar with technique
Personage can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to this hair
The equivalent change or modification that bright Spirit Essence is made, should all cover within the scope of the present invention.
