Abstract

The invention relates to a laser-arc composite partition additive manufacturing process and device. According to the manufacturing process and device, the problem that during a single heat source additive manufacture, the low cost, the high production efficiency and the high forming precision cannot be simultaneously achieved is solved, and the flexible intelligent manufacturing of the part withthe complex structure is realized. The production cost is reduced, the production efficiency is improved, and meanwhile, the part with excellent performance is obtained. The additive manufacturing process comprises a forming part flexible intelligent manufacturing area division, the process of each area of the forming part is selected and determined, and finally the additive manufacturing experiment is carried out. The additive manufacturing device comprises an MIG welding machine, a TIG welding machine and a laser, wherein the central controller adjusts the heat source according to a set program, and parts which are not started to be used in the device can be lifted and placed one side by a system when the additive manufacturing experiment is carried out.

Description

Technical field:

[0001] The invention belongs to the field of composite energy additive manufacturing, and specifically relates to a process and equipment for additive manufacturing using laser-arc composite heat sources, which can realize highly flexible, high-efficiency, and high-quality additive manufacturing. Background technique:

[0002] Arc additive manufacturing technology has the advantages of high efficiency, low cost, and good applicability of metal materials; however, there is a certain gap between the forming accuracy of arc additive manufacturing parts and net shape parts, and the residual stress is relatively large. Therefore, low cost, high production efficiency, and high molding accuracy cannot be achieved at the same time when performing additive manufacturing with a single heat source.

[0003] The laser-arc composite heat source can give full play to their respective advantages and make up for their respective deficiencies at the same time. The addition ...
