Abstract
The invention relates to a new process for manufacturing a cold stamping, deep drawing and material increasing sheet material, which is characterized in that a progressive die is utilized to carry out cold stamping and deep drawing on the sheet material, the sheet material once reaches the material and the depth required by final forming when being subjected to the first cold stamping and deep drawing, namely the deep drawing height is once in place, the sheet material is only gradually reduced in the radial dimension and gradually thickened in the wall thickness from the second stamping to the last stamping, and the purpose of deep drawing and material increasing is achieved. According to the novel process for manufacturing the plate by cold stamping and deep drawing, the required material and depth in final forming are achieved at one time during cold stamping and deep drawing, namely the deep drawing height is in place at one time, the local thickening of the plate is realized through the flowing of radial materials, the phenomenon of multiple deep drawing hardening of the material is solved, and raw materials are saved; the service life of the die is prolonged, and the cost of parts is reduced; the mould has simple structure and is convenient for maintenance; the stability of mass production is improved, and the yield and the quality of products are improved.
Description
Technical Field
The invention relates to a cold stamping process, in particular to a novel process for manufacturing a plate by cold stamping and deep drawing additive.
Background
At present, the depth of a product manufactured by a cold stamping and deep drawing process of a plate by utilizing a progressive die is formed by multiple stamping, namely, the product reaches a certain depth during the channel stamping, the depth is gradually increased every time from the second stamping to the last stamping, the radial size is gradually reduced, and the depth and the radial size meet the forming requirements after the last stamping is finished. The traditional process is that the material is deep drawn for many times and then is piled and extruded downwards to achieve the purpose of locally thickening the metal plate, and has the following defects: after multiple deep drawing, the material is seriously hardened and the deep drawing difficulty is large; the material is obviously thinned in the drawing process, and the material is easy to have defects when stacked; the structure of the mould is complex, and the mass production is extremely poor; maintenance of the mold is difficult.
Disclosure of Invention
The invention aims to provide a novel cold stamping and drawing additive manufacturing process for a plate, which is simple and convenient, can thicken the plate when a progressive die is used for stamping, overcomes the phenomenon of material hardening caused by multiple times of drawing, has a simple structure, reduces the cost and improves the yield and the quality of products.

Detailed Description
As shown in fig. 1: the invention relates to a new process for manufacturing a cold stamping, deep drawing and material increasing sheet material, which is characterized in that a progressive die is utilized to carry out cold stamping and deep drawing on the sheet material, the material and the depth required by final forming are achieved once when the sheet material is subjected to cold stamping and deep drawing for the first time, the material refers to the material quantity required by thickening of the sheet material during deep drawing of subsequent processes, namely the deep drawing height is in place once, the radial dimension is gradually reduced during the second time to the last stamping, and the wall thickness is gradually thickened, so that the purpose of deep drawing and material increasing is achieved. The material and depth required by final forming are achieved at one time during cold stamping and deep drawing, namely the deep drawing height is in place at one time, and the local thickening of the plate is realized through the flowing of radial material, so that the phenomenon of multiple deep drawing hardening of the material is solved, and raw materials are saved; the service life of the die is prolonged, and the cost of parts is reduced; the mould has simple structure and is convenient for maintenance; the stability of mass production is improved, and the yield and the quality of products are improved.
