Problems solved by technology

Therefore, the above method is used for processing, because it needs to be annealed after one stretch, so there are many processing steps and the production efficiency is low.
And in the process of processing, especially in the process of processing into right-angle deep-drawn products such as lithium battery casings, cracks, strains, and pull-through phenomena are prone to occur, which affects the qualified rate of finished products and increases the cost of manufacturers.

Abstract

The invention provides a processing method for processing a stainless steel thin-walled member applied in the field of processing of stainless steel thin-walled members. The method comprises: a step of continuous stretching for N times, a step of tempering treatment, and a step of alternated treatment of stretching for K-N times and tempering. By adopting twice continuous deformation stretching and then carrying out a process of once annealing treatment, the processing method reduces the annealing times so as to reduce the processing procedure, save the processing time and improve the processing efficiency.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing method for stainless steel thin-walled parts. Background technique [0002] Stainless steel products are favored by people for their exquisite appearance, excellent corrosion resistance, high temperature oxidation resistance and high and low temperature strength, and are more and more widely used in decoration, light industry, civil hardware, kitchen equipment and utensils and other industries . Since the appearance quality requirements of such products are relatively high, and most of them are directly stamped from stainless steel sheets, the requirements for the entire processing technology of the products are very high. Because stainless steel has a high yield point, high hardness, and significant cold work hardening effect, when the stainless steel sheet is deep-drawn, the thermal conductivity is worse than that of ordinary low-carbon steel, resu...
