Description

A kind of sieve punching operation mold

Technical field

The utility model relates to sieve punching field shaping technique more particularly to a kind of sieve punching operation molds.

Background technique

It is known, it in the forming process of sieve, is arranged in lower die by the way that multiple red needles are arranged on shaping upper Multiple holes corresponding with upper mold red needle drive upper mold to push, the steel plate being placed between upper and lower mould are passed through by press device Punching is worn, is realized with this and operation is punched out to relatively thin steel plate, but in practical punch process, because of used steel plate Thickness majority is relatively thin, and after upper and lower mould molds punching, red needle and steel plate are because of mantle friction reason, it is not easy to which withdrawing, i.e. red needle exist It is not easy to fall off on sieve, if staff takes by hand, there is low efficiency and it is easy to cause the curved disadvantage of screen surface End.

How to be improved by technology for the drawback in the prior art as industry technical staff, is designed a special It, can be on the basis of guaranteeing shaping efficiency for punching die used in sieve punching operation, it is easier to which sieve of taking is this Industry technology personnel technical problem urgently to be resolved.

Summary of the invention

The purpose of this utility model is to provide a kind of sieve punching operation molds, to solve existing in the prior art Foregoing problems.

To achieve the goals above, the technical solution adopted in the utility model is as follows: a kind of sieve punching operation mold, Including a upper cover plate, the underface of upper cover plate, bolt is fixed with a filler strip respectively for front and rear sides, the two of setting in front and back It is placed with multiple blob of viscoses in gap between a filler strip, the lower section of blob of viscose is a knockout plate, the width of knockout plate and blob of viscose It is of same size；Upper mold crab bolt is fixed by former and later two filler strips in the bottom of knockout plate, on the cope plate, left and right The front and back edge of two sides, which is all inlayed, is provided with a guide sleeve, and on cope plate, it is multiple heavy to be provided with immediately below knockout plate Hole, all counterbores run through cope plate design up and down, are placed with the mandril of a T-type in each counterbore, the top of mandril and upper Template either flush is lower than upper mold plate top surface, and the lower section of the cope plate is one piece of red needle fixed plate, the red needle It is fixed with more red needles in fixed plate, it is solid to pass through top fixing sleeve at the corner of front and back respectively for the left and right sides of red needle fixed plate Surely it is fixed blanking plate by four interfix sets after having a small guide post, the small guide post to run through red needle fixed plate, The blanking plate is fixed on small guide post by four interfix sets, at the center of blanking plate, more red needles just under Side is provided with corresponding punching, the punching and red needle quantity and size matching；Under natural conditions, the lower end of mandril is run through It is withstood on the top surface of blanking plate after red needle fixed plate；The underface of blanking plate is a molding lower die, and molding lower die bolt is fixed In lower template, the punching being provided in lower die with equal number on blanking plate and size is formed；The left and right sides of lower template, it is right Answer the guide sleeve on cope plate, at left and right sides of the lower template before and after edge all inlay and be provided with a guide post, guide pillars and bushes Matching setting；In the molding lower die, the left and right sides respectively corresponds small guide post fixed in red needle fixed plate and is provided with four A small guide sleeve, the small guide sleeve and small guide post are corresponding to be used.

At the intermediate region of blanking plate, top is fixed at least two intermediate guide posts by interfix set, described Intermediate guide post run through red needle fixed plate upward, corresponding all intermediate guide posts are provided with and centre guide post etc. on cope plate With the guide pillar hole of quantity, all intermediate guide posts are inserted into guide pillar hole in its natural state.

The beneficial effects of the utility model are: by designing above mandril is arranged, upper in the utility model on cope plate The bottom setting red needle fixed plate and blanking plate of template, then in the bottom of blanking plate setting molding lower die, make to sieve punching When industry, by the red needle and molding lower die combination in red needle fixed plate, sieve punching is formed, to prevent sieve from red needle It is deformed when exiting, through the reaction force acts of blob of viscose on knockout plate, knockout plate presses mandril, by depressing under mandril Flitch is acted with this and releases sieve after molding in red needle, by using the utility model product, can effectively be avoided into Sieve after type deforms, while can also make sieve fast-falling from red needle, and the effective punching for improving sieve forms effect Rate, to sum up, the utility model novel in structural design, high punching efficiency is a kind of ideal sieve punching operation mold.
