Composite die for edge cutting and punching

Abstract

The invention discloses a composite die for edge trimming and punching, comprising an upper die plate, a lower die plate, an upper die shank being fixedly mounted on the upper die plate, and a guide pillar and a guide sleeve in sliding fit being respectively fixed between the upper die plate and the lower die plate. The lower end face of the upper die plate is fixedly mounted with a male die backup plate and a male die dead plate successively. The lower center and the edge of the male die dead plate are fixedly mounted with a punching male die and an edge cutting female die. The upper end face of the lower die plate is fixed with a female die backup plate and a female die dead plate. An edge cutting male die which is provide with steps inside is fixedly mounted in the female die dead plate. A punching female die which has a turnup at the lower end is fixedly mounted on the steps of the cutting edge female die. The invention integrates edge cutting and punching into one die, which shortens production line, reduces labor intensity, raises working efficiency and lowers production cost.

Description

technical field [0001] The invention relates to a trimming and punching die, in particular to a composite die for trimming and punching a cylinder body of an idler roller. Background technique [0002] For the workpiece of the idler cylinder that needs to be trimmed and punched, it generally needs to go through three processes. First, the parts are trimmed on the trimming machine, then punched, and finally placed in the shaping machine for shaping, eliminating the need for trimming and punching. The impact of punching on parts can not only require three processes, but also require a lot of equipment, resulting in long production lines, high labor intensity, low productivity and high production costs. In order to solve the above technical problems, someone has designed a mold that can punch holes, cut edges, and shape at one time, but the structural design is unreasonable, resulting in poor processing efficiency of parts and low processing efficiency.

[0002] For the workpiece of the idler cylinder that needs to be trimmed and punched, it generally needs to go through three processes. First, the parts are trimmed on the trimming machine, then punched, and finally placed in the shaping machine for shaping, eliminating the need for trimming and punching. The impact of punching on parts, so that not only three processes are required, but also a lot of equipment is required, resulting in long production lines, high labor intensity, low productivity and high production costs

In order to solve the above technical problems, some people have designed a mold that completes punching, trimming, and shaping at one time, but the structural design is unreasonable, resulting in poor processing efficiency of parts and low processing efficiency.
