Device conducting composite manufacturing on basis of laser technology

Abstract

The invention discloses a device conducting composite manufacturing on the basis of a laser technology. The device comprises a sealed forming chamber, an inert protective gas source and a machining forming platform. The inert protective gas source is connected with the sealed forming chamber. The machining forming platform is arranged in the sealed forming chamber, and a light path selection system is arranged over the machining forming platform. A machining station is arranged on the machining forming platform, and the machining forming platform is arranged on a guide rail and can slide forwards and backwards through the guide rail. The light path selection system comprises a shock reinforcing independent laser light path, an additive independent laser light path and a subtractive independent laser light path. The light paths are arranged in the direction of the guide rail, and all the independent laser light paths do not share equipment and are arranged over the machining forming platform. According to the device, the laser shock reinforcing technology and the laser additive and subtractive technology are integrated, the forming precision, the surface quality, the organization performance and the residual stress state of a complex fine additive workpiece are improved, and one-stop high-efficiency high-precision and high-performance additive workpiece preparation is achieved.

Description

Technical field [0001] The invention belongs to the technical field of laser processing and relates to a device for compound manufacturing based on laser technology. Background technique [0002] Selective Laser Melting (SLM) is a laser additive manufacturing technology based on material discrete-gradual accumulation method to manufacture solid parts. It uses high-power laser as the heat source to melt metal powder layer by layer to directly manufacture Complicated and fine-structured parts (high processing accuracy). This technology can realize fast and moldless near-net molding of dense materials with complex structures. It provides new ideas for the integrated preparation of complex and fine-structured parts, especially for aerospace The molding of key precision parts in the fields of, medical equipment, precision machine tools, electronic communications and other fields provides a simple, fast, low-cost, green flexible manufacturing technology from powder to complete parts, a...
