Abstract
The invention discloses a kind of piercing punch structure, including the punch-pin in cylinder, punch-pin lower end surface center is provided with blind hole, blind hole is in back taper, rubber column is provided with blind hole, rubber column upper end offsets with blind hole bottom surface, rubber column lower end stretch out blind hole, blind hole taper surface upper and lower end respectively with blind hole bottom surface and punch-pin lower end surface circular sliding slopes.
Description
Technical field
The present invention relates to a kind of piercing punch 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：Overcoming deficiency in the prior art, there is provided a kind of scrap-bounce that prevents
Piercing punch structure.
The technical solution adopted for the present invention to solve the technical problems is：A kind of piercing punch structure, including in cylinder
Punch-pin, punch-pin lower end surface center is provided with blind hole, and blind hole is in back taper, is provided with rubber column in blind hole, rubber column upper end with it is blind
Bottom hole face offsets, and blind hole is stretched out in rubber column lower end, and blind hole taper surface upper and lower end is justified with blind hole bottom surface and punch-pin lower end surface respectively
Arc is connected.
The beneficial effects of the invention are as follows：Simple in construction, practicality of the invention, it is adaptable to which diameter is less than 6mm punch-pin, and thin
Type stamping material.During punching press, the obstruction of rubber column lower end is received when being jumped on punched scrap, thus solves institute in background technology
The problem of stating.
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. punch-pin；2. blind hole；3. rubber column；4. taper surface；5. punched scrap；6. cavity plate.
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.
A kind of piercing punch structure as shown in Figure 1, including in the punch-pin 1 of cylinder, the lower end surface center of punch-pin 1 is provided with
Blind hole 2, blind hole 2 is in provided with the rubber column 3 that the straight hole of cavity plate 6 is jumped out on prevention punched scrap 5, rubber column 3 in back taper, blind hole 2
Upper end offsets with the bottom surface of blind hole 2, and blind hole 2 is stretched out in the lower end of rubber column 3, and the small bore end of back taper blind hole 2 can block elastic rubber column 3
Come off out of blind hole 2, the upper and lower end of 2 taper surface of blind hole 4 respectively with the bottom surface of blind hole 2 and the lower end surface circular sliding slopes of punch-pin 1.
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.
