Abstract
The utility model discloses a standard type pre-punching punch with long service life which comprises an upper die holder and a lower die holder, and the upper die holder and the lower die holder are arranged by corresponding to each other up and down. The lower surface of the upper die holder is provided with an upper base plate, an upper clamp plate, a blocking plate and a stripper plate in sequence, and meanwhile, the upper surface of the lower die holder is provided with a lower cushion plate and a lower die plate in sequence. The standard type pre-punching punch with long service life improves a punch structure specifically, prevents the punch from being easily damaged and fractured in the process of punch press stamping, effectively prolongs service life of the punch, facilitates saving production cost and promotes high-efficiency production.
Description
Technical field
The utility model belongs to the drift technical field in the mechanical fitting, relates to especially a kind of canonical form high life passing punch.
Background technology
During mould was produced, conventional drift was all longer, so cause easily the situations such as drift rapid wear, fracture when punch press carries out the punching press action, had not only affected manufacturing schedule, and had caused extra cost allowance, was unfavorable for carrying out efficiently integral production.
The utility model content
The purpose of this utility model is to solve problems of the prior art, and a kind of canonical form high life passing punch is provided.
The utility model is achieved by the following technical programs:
A kind of canonical form high life passing punch comprises upper bolster and die shoe that up and down contraposition arranges.Its
In, the upper bolster lower surface is provided with upper padding plate, train wheel bridge, baffle plate and stripper plate successively, and simultaneously, the die shoe upper surface is provided with lower bolster and lower bolster successively.
Be provided with many groups in the stripper plate and take off plate and enter son, be provided with in the lower bolster many groups with take off plate enter the identical and position of quantum count one to one counterdie enter son.
In addition, be embedded with many group drifts in train wheel bridge, baffle plate and stripper plate, wherein to enter quantum count identical with taking off plate for drift quantity, and equal the passing a group and take off plate and enter son of correspondence of every group of drift.Further, the drift head end is equipped with a pressure head, and the pressure head diameter is less than punch diameter.
Be embedded with many group counterdie jigger pins in lower bolster, lower bolster, wherein to enter quantum count identical for counterdie jigger pin quantity and counterdie, and every group of counterdie jigger pin all the one group of counterdie that passes of correspondence enter son.
The utility model usefulness is:
The utility model has been improved punch structure targetedly, and the situations such as the drift rapid wear that has caused when having avoided punch ram, fracture have effectively increased life-span of drift, are beneficial to the saving production cost, promote High-efficient Production.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is partial side TV structure schematic diagram of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Such as Fig. 1 ~ Figure 2 shows that a kind of canonical form high life passing punch that can be used as the utility model preferred embodiment, comprise upper bolster 1 and die shoe 8 that up and down contraposition arranges.Wherein, upper bolster 1 lower surface is provided with upper padding plate 2, train wheel bridge 3, baffle plate 4 and stripper plate 5 successively; Simultaneously, die shoe 8 upper surfaces are provided with lower bolster 7 and lower bolster 6 successively.
Be provided with many groups in the stripper plate 5 and take off plate and enter son 11, be provided with in the lower bolster 6 many groups with take off plate enter the identical and position of sub 11 quantity one to one counterdie enter sub 10.
In addition, be embedded with many group drifts 12 in train wheel bridge 3, baffle plate 4 and stripper plate 5, wherein to enter sub 11 quantity identical with taking off plate for drift 12 quantity, and every group of drift 12 is all corresponding passes one group and take off plate and enter sub 11.Further, drift 12 head ends are equipped with a pressure head 13, and the diameter of pressure head 13 is less than the diameter of drift 12.
Be embedded with many group counterdie jigger pins 9 in lower bolster 7, lower bolster 6, wherein to enter sub 10 quantity identical for counterdie jigger pin 9 quantity and counterdie, and every group of counterdie jigger pin 9 all the corresponding one group of counterdie that passes enter sub 10.
Concrete, described drift 12 length are take 65.7mm as good, and described drift 12 diameters are take 4.5mm as good simultaneously, and described pressure head 13 diameters are take 2.75mm as good, and described counterdie jigger pin 9 diameters are take 3.7mm as good.
It is domatic that the position that joins with pressure head 13 on the drift 12 is provided with the arc that plays transitional function, and the domatic diameter of this arc is take 0.5mm as good.
