Blanking and drawing die

Abstract

The invention discloses a blanking and drawing die, comprising an upper die plate and a lower die plate, a die shank being fixedly mounted on the upper die plate, a female-male dead plate being fixedly mounted on the lower end of the upper die plate, a blanking and drawing male-female die being fixedly mounted on the lower end of the female-male dead plate; a backup plate and a lower die dead plate being fixedly mounted on the upper end of the lower die plate, a drawing male die and a blanking female die being mounted on the upper end of the lower die, the drawing male die cooperating with the mold cavity of the blanking and drawing male-female die, the mold cavity of the blanking female die cooperating with the blanking and drawing male-female die. By simultaneously achieving drawing and blanking, process time is shortened and meanwhile punching quality is improved, and processing efficiency is clearly increased.

Description

technical field [0001] The invention relates to a blanking and deep drawing mold. 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. Contents of the invention [0003] The purpose of the present invention is to provide a blanking and dee...

Problems solved by technology

[0002] For the workpiece of the roller 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.
