Abstract

A track shoe bolt hole piercing die relates to a die piercing dies on a track shoe, which aims to resolve he problems that at present, piercing bolt holes on a track shoe is slow and the like. The track shoe bolt hole piercing die comprises a lower die plate, a concave die bolster, a concave die holder which are fixedly connected through pin shafts and screws; a concave die is arranged on the concave die holder; a stripper plate fixed onto the lower die plate through a vertical post is arranged above the concave die holder; a convex die holder is arranged above the stripper plate; a convex die is arranged below the convex die holder; a convex die bolster, an upper die plate and a convex die holder are arranged above the convex die holder and fixedly connected through pin shafts and screws; a guide sleeve is arranged below the upper die plate; the upper end of a guide post extends into the guide sleeve; the lower end of the guide post is fixed onto the lower die plate; a positioning post is arranged on the convex die holder; a V-shaped opening is arranged at the lower end of the positioning post; a spring is arranged at the upper end of the positioning post; the upper end of the spring is abutted onto a screw cap; the screw cap is fixed onto the convex die holder through a sleeve; and a bolt on the lower portion of the sleeve extends into a groove on the lateral surface of the positioning post. The track shoe bolt hole piercing die has the advantages of high hole piercing accuracy and fast speed.

Description

Creeper tread is towards the bolt hole mould

Technical field:

The utility model relates to a kind of mould that can go out bolt hole on creeper tread.

Background technology:

The processing bolt hole all is to hole with creeper tread auger shell keyhole mould on creeper tread at present, and its shortcoming is that the positional precision of bolt hole is low, and penetration rate is slow, and production efficiency is low.

Summary of the invention:

Technical problem to be solved in the utility model provides the high creeper tread of a kind of positional precision that can be on creeper tread improves bolt hole during the processing bolt hole and production efficiency towards the bolt hole mould.

Above-mentioned purpose is achieved in that it comprises lower bolster, there is the die backing plate lower bolster top, there is die block die backing plate top, lower bolster, die backing plate and die block are connected and fixed by bearing pin and screw, be inlaid with several dies on the upper surface of die block, there is stripper the top of die block, stripper is established the hole in the position of corresponding die, stripper is fixed on the lower bolster by the stripper pillar, leave certain space between die block and the stripper, there is punch retainer the top of stripper, the lower surface of punch retainer is provided with upright position and quantity with die identical punch relative with die, there is convex mould pad the punch retainer top, there is cope match-plate pattern the convex mould pad top, punch retainer, convex mould pad and cope match-plate pattern are connected and fixed by bearing pin and screw, both sides at the cope match-plate pattern lower surface are respectively equipped with guide pin bushing, the guide pillar upper end is stretched in the guide pin bushing and the little matched in clearance of guide pin bushing, the guide pillar lower end is fixed on the lower bolster, also has reference column on the punch retainer, there is a V-type mouth reference column lower end, there is spring the reference column upper end, the spring upper end withstands on the nut, nut is fixed on the punch retainer by sleeve, there is groove the side of reference column, lower cartridge has bolt to stretch in this groove, comes off to prevent reference column.

Using method and advantage: cope match-plate pattern and lower bolster are fixed on the upper and lower die holder of hydraulic press by screw respectively, processed workpiece creeper tread enters between die block and the stripper, carry out longitudinal register by existing auxiliary mould, the V-type mouth of reference column is stuck on the creeper tread muscle, carry out located lateral, under the effect of hydraulic press, cope match-plate pattern moves downward together with punch retainer and punch then, and punch stretches out at creeper tread from the hole of stripper goes out needed bolt hole.The bolt hole position precision height that uses this device on creeper tread, to go out, process velocity is fast, and production efficiency can improve 3-4 doubly.
