Metal workpiece destressing treatment process

Abstract

The invention discloses a metal workpiece destressing treatment process. The process comprises the following steps that blanking is carried out, and specifically electromagnetic valve elements with the same scale and size are selected; turning is carried out, and specifically grouped battery valve elements are turned; milling is carried out, and specifically the turned battery valve elements are milled; burr removal is carried out, and specifically deburring is conducted on the same batch of battery valve elements in each group; braking is carried out, and specifically, all the battery valve elements are baked at the same time; high-temperature and low-temperature circulation is conducted, and specifically, high-temperature and low-temperature circulation heating is conducted on the bakedvalve elements; and cleaning is carried out, and specifically, after valve elements of the same batch are naturally cooled, synchronous cleaning is conducted. By means of the metal workpiece destressing treatment process, the production forming quality of products can be greatly improved, stress deformation, caused by the stress effect, of the outer surface and the internal local position of a workpiece during production and machining of the workpiece product is effectively avoided, and the production forming precision of the product workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of stress relief treatment, in particular to a stress relief treatment process for metal workpieces. Background technique [0002] Metal workpiece stress relief treatment process is an operation method for stable protection of workpiece forming. In the process of workpiece processing, due to the existence of processing stress, the product workpiece is prone to local and overall problem deformation, which makes the overall structure of the workpiece and The shape changes, so that the product cannot be assembled due to the occurrence of deformation problems, or the pass rate during assembly cannot meet the requirements for production and use, and the pass rate of its assembly is low, which increases the economic cost of product workpiece processing, resulting in The damage to the economic property produced by the product workpiece will also affect the production and processing efficiency of the product workpie...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a metal workpiece stress relief treatment process to solve the above-mentioned background technology. When the existing workpiece product is processed, the local and overall deformation of the product is large, resulting in qualified assembly and assembly pass rate of the product. Only about 30%, under the action of subsequent workpiece processing, after ensuring that the deformation rate of the product is reduced, there will be local changes in the size of the product, resulting in the inability to guarantee the accuracy of the product in production and use, thus affecting the fast and effective production of the workpiece production, reduce the processing efficiency of the product, and lead to the problem that the final molding quality of the workpiece product is not high
