A metal mold 3D printing laser micro-area processing method

Abstract

The invention relates to a metal mold 3D printing laser micro-area processing method, comprising the following steps: 1) a digital-analog block pretreatment stage; 2) a modeling layered scanning stage; 3) a laser cladding deposition forming stage, in which In the stage: after the laser cladding deposition of the first slice layer, the micro-area in the slice layer is subjected to secondary laser surface strengthening treatment, and when the secondary laser quenching surface treatment of the slice layer micro-area is completed Afterwards, the second layer of layered layered laser cladding deposition and the secondary laser surface strengthening and quenching treatment of the micro-region in the second layered layered layered layer are carried out, and so on, the laser cladding forming of all the layered layers is completed, forming Metal mold forming parts; 4) post-processing stage, including heat treatment, polishing and machining. It has the advantages of reasonable design, convenient operation, reliable mechanical properties of metal mold forming parts, short processing and manufacturing operation time, and effectively reducing labor intensity and processing costs of operators.

Description

technical field [0001] The invention relates to the technical field of mold processing and manufacturing by laser cladding, in particular to a laser micro-area processing method for 3D printing of metal molds. Background technique [0002] As an indispensable manufacturing tool in modern industrial production, molds have a large amount of production and use every year. During the use of molds, problems such as wear and cracking will inevitably occur. Common mold repair methods include welding In the process of welding repair, there are defects such as high labor intensity of operators, low work efficiency, complicated process, waste of metal powder materials, and low surface treatment performance. Therefore, it is of great research significance to propose a more reasonable metal mold forming design and manufacturing method to obtain higher quality metal molds. Contents of the invention [0003] In view of the above-mentioned deficiencies in the mold processing and manufac...
