Abstract
The utility model discloses a punching punch head which comprises a stress portion, a guide portion and a punching area. The punching punch head is characterized in that a connecting portion is arranged between the guide portion and the punching area, the connecting portion is shaped like a circular truncated cone, one end of the connecting portion and the guide portion are in the same circle, and the other end of the connecting portion and the punching area are in the same circle; and the stress portion, the guide portion, the connecting portion and the punching area are in an integrated structure. The punching punch head is simple in structure, convenient to use, high in automation efficiency, and good in product quality.
Description
Technical field
The utility model relates to a kind of pierce punch.
Background technology
At present, the progressive die that is used for punched workpiece has been widely used in mechanical manufacturing field, CPU slot connecting plate also is like this, most product, need through the multipass operation, need has corresponding pierce punch for this reason, realizes the continuous automatic production processing of this product, drift also is punch, patrix, formpiston, red needle etc., and drift is divided into A type drift, T-shaped drift, special-shaped plunger chip.Drift is mounted in the metal parts in the diel, is applied to contact with the direct of material, makes material generation deformation, cuts material.
Mold and punching head generally adopts high-speed steel and wolfram steel etc. as material, high-speed steel drift and wolfram steel drift etc. are arranged, and high-speed steel is the most frequently used material, and commonly used have CR12, CR12MOV, asp23, skd11, skd51, skd61 etc.The wolfram steel material generally is used on the punching and shearing die of having relatively high expectations.Drift is to cooperate plunger rod, drift nut, the female together use of punching.The general steel tower factory punching purposes that is used for.The processing of HL blade specialty: numerical control steel tower factory drift, punching mother, plunger rod, drift nut have had decades, the exhibition of producing occur to numerical control production from general car, the at present fully integrated streamline production of numerically controlled lathe.
The utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to use, pierce punch that efficient is high, is used for finishing the processing of the first Cheng Chongkong blanking of product.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is: pierce punch, comprise: force part, guiding position and punch area, it is characterized in that: be provided with connecting portion in the middle of described guiding position and the punch area, described connecting portion becomes truncated cone, described connecting portion one end and guiding position together circle, the other end and punch area are with circle.
Described force part, guiding position, connecting portion and being integral of punch area structure.
As preferred version, the length L of described pierce punch is 42mm; The height T of described force part is 5 mm, and diameter H is 5 mm; The diameter D at described guiding position is 3 mm, and the diameter P of described punch area is 2.85 mm.
Beneficial effect: the pierce punch that the utility model provides, simple in structure, easy to use, automation efficient height, good product quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, pierce punch, comprise: force part 1, guiding position 2 and punch area 4, it is characterized in that: be provided with connecting portion 3 in the middle of described guiding position 2 and the punch area 4,3 one-tenth truncated cones of described connecting portion, described connecting portion 3 one ends and guiding position 2 together circle, the other end and punch area 4 are with circle.Described force part 1, guiding position 2, connecting portion 3 and punch area 4 being integral structures.
As preferred version, the length L of described pierce punch is 42mm; The height T of described force part 1 is 5 mm, and diameter H is 5 mm; The diameter D at described guiding position 2 is 3 mm, and the diameter P of described punch area 4 is 2.85 mm.
Below disclose the utility model with preferred embodiment, so it is not to limit the utility model, and all employings are equal to replaces or technical scheme that the equivalent transformation mode obtains, all drops within the protection domain of the present utility model.
