Trimming and punching die

Abstract

The invention discloses a trimming and punching die, which comprises an upper template and a lower template, wherein a guide pillar and a guide sleeve which are in mutual sliding fit are respectively fixedly arranged between the upper template and the lower template; a male die backing plate and a male die fixing plate are sequentially and fixedly arranged on the lower end surface of the upper template; a punching male die and a trimming female die are respectively and fixedly arranged at the center and the edge below the male die fixing plate; a female die backing plate and a female die fixing plate are fixedly arranged on the upper end surface of the lower template; a trimming male die and a punching female die are sequentially matched in the female die fixing plate; a die cavity of the punching male die is matched with that of the punching female die; and a die cavity of the trimming male die is matched with that of the trimming female die. According to the trimming and punching die disclosed by the invention, the punching and the trimming are finished in one set of dies, thus a production line is shortened, the labor intensity is reduced, the production efficiency is improved and the production cost is reduced.

Description

technical field [0001] The invention relates to a trimming and punching die, in particular to a trimming and punching die for 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.

Problems solved by technology

[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.
