Problems solved by technology

This results in poor accuracy in formulating heat treatment process requirements, which can easily lead to failure of mechanical parts to meet the required mechanical, physical and chemical properties after heat treatment, causing problems such as high failure rate of products after heat treatment
[0005] Moreover, the current heat treatment of mechanical parts pays too much attention to the relationship and change law between the properties of metal materials and their composition and internal structure, but does not organically link the heat treatment process requirements with the processing of mechanical parts, which easily leads to the formulation of Incomplete heat treatment process requirements affect the performance of mechanical parts after heat treatment

Abstract

The invention relates to the technical field of heat treatment, in particular to a determination method of mechanical part heat treatment strengthening process requirements. The method comprises the following steps: a mechanical part is provided; a lowest hardness distribution curve of the mechanical part is determined; and a heat treatment strengthening process of the mechanical part is determined based on the lowest hardness distribution curve of the mechanical part. The heat treatment strengthening process of the mechanical part is determined based on the lowest hardness distribution curveof the mechanical part, so that the requirements of the strength on the hardness can be considered more sufficiently, more reasonable and more reliable heat treatment process requirements are formulated, the mechanical part is heated to preferably satisfy the needed mechanical performances, physical performances and chemical performances, and the product reject ratio of the mechanical part after heat treatment is reduced.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a method for determining heat treatment strengthening process requirements of mechanical parts. Background technique [0002] Heat treatment strengthening is one of the important processes in mechanical manufacturing. In order to make mechanical parts have the required mechanical properties, physical properties and chemical properties, in addition to rational selection of materials and various forming processes, heat treatment strengthening processes are often essential. [0003] Heat treatment strengthening heats the parts to a suitable temperature in a certain medium, and keeps them at this temperature for a certain period of time, and then cools them in different media at different speeds, which does not change the shape of the mechanical parts and the overall chemical composition, but It is to improve the mechanical properties of the parts such as hardness, wear resist...
