Abstract

The utility model provides a long-service life stamping die. The long-service life stamping die comprises a punching machine platform, a lower die plate, an upper clamp plate, a stripper plate, a punch, a guide column and steel ball bushes, wherein the upper clamp plate is fixed on an upper die base; the stripper plate is positioned below the upper clamp plate; the punch is arranged on the upper clamp plate and penetrates through the stripper plate; the guide column is fixed on the upper die base through a bolt; the lower die plate is arranged on the punching machine platform; the position of the lower die plate, which corresponds to the guide column, is provided with a lower die guide sleeve; the steel ball bush is arranged in the lower die guide sleeve; the stripper plate is provided with an upper die guide sleeve; the guide column penetrates through the steel ball bush; a spring is arranged underneath the lower die guide sleeve; and the steel ball bush is also arranged in the upper die guide sleeve. According to the long-service life stamping die, a steel ball bush structure is adopted, zero clearance fit is realized, and steel balls roll between the guide column and the guide sleeves, so that friction between the guide column and the guide sleeves is reduced; and therefore, the zero clearance fit of free up-and-down movement can be realized, and the accuracy of the die and the lubrication effect in a production process can be improved conveniently.

Description

A kind of high life diel
Technical field
Hardware stamping industry mould structure design field, particularly a kind of high life diel.
Background technology
Traditional guide pillar guide pin bushing structure is directly contact, and train wheel bridge is fixed on the upper bolster, and stripper plate is positioned at the below of train wheel bridge; Guide pillar is fixed on the upper bolster through screw, and the position of corresponding guide pillar is provided with guide pin bushing on the lower bolster, and this structure is when the punch die high speed stamping; Guide pillar and guide pin bushing are prone to hold plucking, guide pillar is overheated burns; Fit clearance is just increasing, and the die-cut low precision of mould causes the poor quality towards part.Along with the development and the progress of society, existing conventional molds structure is backward, has satisfied not the life-span of product.When production lot was big, the guide-post of die-set guide pin bushing lost efficacy to change and will have a strong impact on product quality, also bring more costs occur the output of production not enough, to open the backup mould, cost increases.
Summary of the invention
The utility model proposes for the shortcoming that overcomes above prior art existence, and the technical problem that it solved provides a kind of simple in structure, the diel of long service life.
For this reason; The utility model provides a kind of high life diel; Comprise punch press platform, lower bolster, train wheel bridge, stripper plate, drift, guide pillar and steel ball lining, wherein train wheel bridge is fixed on the upper bolster, and stripper plate is positioned at the below of train wheel bridge; Drift is installed on the train wheel bridge and passes stripper plate, and guide pillar is fixed on the upper bolster through screw.Lower bolster is installed on the punch press platform, and the position of corresponding guide pillar is provided with the counterdie guide pin bushing on the lower bolster, and the steel ball lining is installed in the counterdie guide pin bushing, and stripper plate is provided with upper die guide sleeve, and guide pillar passes the steel ball lining, and counterdie guide pin bushing below is equipped with spring.
The steel ball lining is installed in the described upper die guide sleeve.
The beneficial effect of the utility model is:
The utility model is simple in structure; Reasonable in design, employing be the steel ball bush structure, promptly do not have the gap interference fit; Roll through the steel ball between guide pillar and the guide pin bushing; Reduced the friction between guide pillar and the guide pin bushing, cooperated, helped improving the precision of mould and the lubricant effect in the production process like this thereby reach free up and down no gap.The frame mode life-span with respect to common generally can only reach about 1000 times, and the utility model can satisfy the production requirement of handware in enormous quantities, reaches the life-span of punching press more than 20000 times.
Description of drawings
Fig. 1 is the described high life diel of a utility model structural representation.
1-train wheel bridge, 2-stripper plate, 3-lower bolster, 4-upper die guide sleeve, 5-guide pillar, 6-spring, 7-upper bolster, 8-steel ball lining, 9-drift, 10-counterdie guide pin bushing, 11-punch press platform.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation.
As shown in Figure 1; A kind of high life diel; Comprise punch press platform 11, lower bolster 3, train wheel bridge 1, stripper plate 2, drift 9, guide pillar 5 and steel ball lining 8, wherein train wheel bridge 1 is fixed on the upper bolster 7, and stripper plate 2 is positioned at the below of train wheel bridge 1; Drift 9 is installed on the train wheel bridge 1 and passes stripper plate 2, and guide pillar 5 is fixed on the upper bolster 7 through screw.Lower bolster 3 is installed on the punch press platform 11; The position of corresponding guide pillar 5 is provided with counterdie guide pin bushing 10 on the lower bolster 3; Steel ball lining 8 is installed in the counterdie guide pin bushing 10, and stripper plate 2 is provided with upper die guide sleeve 4, and guide pillar 5 passes upper die guide sleeve 4; Steel ball lining 8 is installed in the upper die guide sleeve 4, and counterdie guide pin bushing 10 belows are equipped with spring 6.
What the utility model adopted is the steel ball bush structure; Promptly there is not the gap interference fit; Roll through the steel ball between guide pillar 5 and the steel ball lining 8; Reduced the friction between guide pillar 5 and the steel ball lining 8, cooperated, helped improving the precision of mould and the lubricant effect in the production process like this thereby reach free up and down no gap.The frame mode life-span with respect to common generally can only reach about 1000 times, and the utility model can satisfy the production requirement of handware in enormous quantities, reaches the life-span of punching press more than 20000 times.
