Embodiment Construction

[0025] figure 1 It is the prior art thinning and deep drawing process. The cake product (cake state) is made into a barrel shape by ordinary deep drawing, and then the ordinary deep drawing surface is strongly squeezed and drawn by thinning and deep drawing. The deep surface is obviously thinner, thus showing a mirror effect, so as to meet the quality requirements of the product.

[0026] figure 2 In the composite drawing process of the composite thinning and drawing tooling of the present invention, the product (cake state) directly adopts the composite thinning and drawing, which reduces one process and improves efficiency. At the same time, because two deep drawing uses one positioning, the positioning accuracy is improved and the product quality is improved.

[0027] image 3 Among them, the equipment slider 1 is equipped with an upper template 3, the upper template 3 is equipped with an upper backing plate 5, and the upper backing plate 5 is equipped with a punch 6. They are ...

Abstract

A compound thinning and deep-drawing tooling, comprising an upper template and a lower template; the upper template is provided with corresponding punches, the lower template is provided with a die fixing plate, the inner diameter of the die fixing plate is in a stepped structure, and is equipped with a common drawing Deep, thinning and deep-drawing two-stage die can realize the second drawing in one process action; the lower template is equipped with a support plate, and the die fixing plate is equipped with a positioning ring. The combination of the two makes the discharge The process is convenient and quick; the fixed seat is equipped with a stripping ring, and the material can be drawn and stripped by using the characteristic that one end can pass through and the other end cannot pass; the lower template is also equipped with a cylinder, and the cylinder piston passes through the fixed seat, which can automatically Quickly push the finished product out of the gap of the holder. Using the invention, the processing process is stable, and the ordinary deep drawing and thinning deep drawing can be completed in one process action, and the feeding, positioning, returning and retrieving of materials are fast and accurate, the operation efficiency is high, and the quality is reliable, which is suitable for large batches production requirements.

Description

Technical field [0001] The invention belongs to the technical field of stamping processing, and relates to a device for compound thinning and deep drawing. Background technique [0002] At present, some belt pulleys in automobile engines are driven by flat belts. Because they work in a high-speed environment, the working surface has extremely high requirements, mainly reflected in the roundness of the working surface itself, the verticality relative to the mounting surface, and the smoothness. Require stricter tolerance control. [0003] According to the use characteristics and quality requirements of the involved products (pulleys), for example, the water pump pulley developed for a customer’s engine is also applied to the pulley drive. Because it works in a high-speed environment, in order to reduce engine vibration and noise, the working surface There are extremely high requirements. The demand for this product exceeds 1.2 million pieces per year, so a production process is ne...
