Edge cutting die of bending wrench

Abstract

The invention discloses an edge cutting die of a bending wrench. The edge cutting die comprises an upper die plate, a lower die plate, a die handle, a guiding column and a guiding sleeve, wherein the upper die plate is fixedly provided with an upper base plate; the upper base plate is provided with an upper fixed plate; an upper male die and a material pressing plate are arranged in the upper fixed plate; a spring is arranged between the material pressing plate and the upper fixed plate; one end of the spring leans against the upper fixed plate; the other end of the spring leans against the material pressing plate; the lower die plate is fixedly provided with a lower base plate; the lower base plate is provided with a lower fixed seat; a lower male die is arranged in the lower fixed seat. According to the edge cutting die of the bending wrench, disclosed by the invention, the production efficiency is high, the die is simple and practical in structure, the operation is convenient, the accuracy of the edge cutting size is high, the consistency is good, and various disadvantages of manual trimming in the past are effectively solved.

Description

technical field [0001] The invention relates to the technical field of stamping dies, in particular to a trimming die used for removing process residues after the forming of bent wrench parts. Background technique [0002] Such as figure 1 The bending wrench in is a part of a certain product, the material is H62Y, the material thickness is 0.4mm, and the product batch is large. The forming of this part belongs to the composite forming of bending mainly and drawing, the straight edge part is bending forming, and the rounded part belongs to drawing forming. According to the structural characteristics of the part, the dimensional accuracy and the equipment conditions, the initial process plan is as follows: blanking of the bottom hole - bending - trimming by the fitter - shaping - punching the side hole. In the initial process plan, due to insufficient attention was paid to how to remove the process residues after the parts were bent and formed, the fitter was only arranged t...

AI Technical Summary

Problems solved by technology

In the initial process plan, due to insufficient attention was paid to how to remove the process residues after the parts were bent and formed, the fitter was only arranged to remove them by manual filing of tire blocks after the bending process. As a result, there were problems in actual production: firstly, The labor intensity is high, the production efficiency is low, the operation is inconvenient, the file is easy to scratch the worker's fingers, and there are unsafe factors; secondly, the accuracy of the trimming size is not easy to guarantee, and the size consistency is poor. The surface roughness of the file trimming is not good
