CN203170793U - Trimming mold structure of blades - Google Patents

Abstract

The utility model provides a trimming mold structure of blades. The trimming mold structure of the blades can avoid the trimming deviation phenomenon caused by blade body position offset when an existing trimming mold performs trimming, therefore, machining of end products after being forged is ensured, and production cost is reduced. The trimming mold structure of the blades comprises a trimming female mold and is characterized in that material stopping blocks are arranged on the trimming female mold and at the outer side end of a lug cavity, and forge piece lugs lean against the material stopping blocks when the trimming is performed.

Description

A kind of shaving die structure of blade

Technical field

The utility model relates to the blade mould forging manufacture field, is specially a kind of shaving die structure of blade.

Background technology

Side cut is one production process after die forging during open die forging, impressing forging is produced, and it is removed overlap after blade forges, and it is a kind of method of removing overlap of using always that edger is cut edge.When edger is worked, blade is subjected to molding pressure, occurring blade easily moves, or because workman's operant level difference, blade may be put in die partially, thereby causes cutting edge afterwards the blade wide deficiency of one side string and the residual overlap of opposite side is more, surplus deficiency when making the forging processed finished products, cause blade to scrap, return later process and produce the increase workload, increase production cost.

Summary of the invention

At the problems referred to above, the utility model provides a kind of shaving die structure of blade, it can solve existing edger when cutting edge since the skew of blade position cause cut inclined to one side phenomenon, thereby the finished product after guaranteeing to forge process, reduce production costs.

Its technical scheme is such, and it comprises trim die and side cut punch, it is characterized in that: on the described trim die, the outboard end of lug die cavity is provided with material blocking block, the forging lug is put and is against on the described material blocking block during side cut.

Adopt the shaving die structure of the utility model blade, its beneficial effect is: its outboard end at trim die lug die cavity is provided with material blocking block, the position-limiting action of the lug of forging is prevented the skew of forging by this material blocking block, thereby guarantee the precision that forging is cut edge, guarantee the reliable realization of subsequent handling, reduce the workload of postorder finished product processing, enhance productivity, reduce production costs; In addition, also make things convenient for the workman to put the material centering, it is simple in structure, be easy to processing realizes.

The specific embodiment

See Fig. 2, Fig. 3 and Fig. 4, the utility model structure comprises trim die 1 and side cut punch 6, and on the trim die 1, the outboard end of lug die cavity 2 is provided with material blocking block 3, the lug 5 of forging 4 is put and is against on the material blocking block 3 during side cut.

Claims (1)

1. the shaving die structure of a blade, it comprises trim die, it is characterized in that: on the described trim die, the outboard end of lug die cavity is provided with material blocking block, the forging lug is put and is against on the described material blocking block during side cut.
