Novel metal powder melting and quick-molding machine

Abstract

The invention relates to a novel metal powder melting and quick forming machine which comprises a frame, a control system, a laser galvanometer scanning device, a powder laying device, a three-cylinder body and a laser, wherein the control system, the laser galvanometer scanning device, the powder laying device, the three-cylinder body and the laser are all arranged on the frame, the laser galvanometer scanning device is in optical connection with the laser, and the laser galvanometer scanning device, the powder laying device, the three-cylinder body and the laser are all connected to the control system. The novel metal powder melting and quick forming machine has the advantages that a nonequilibrium supersaturated solid solution and uniform and fine metallographic structures can be obtained, the density of a formed part is close to 100%, the mechanical performance is equivalent to that of a forging part, the processing time and cost can be obviously reduced, and the development cycle of a new product is shortened. The novel metal powder melting and quick forming machine greatly adapts to the requirements of quick, individuated and flexible development of the modem manufacturing industry and has a broad application prospect in the manufacturing fields of aviation, aerospace, medicine, molds, weaponry and the like.

Description

technical field [0001] The invention relates to the technical field of rapid prototyping equipment, in particular to a novel metal powder melting rapid prototyping machine. Background technique [0002] Although selective laser melting (SLM) technology has developed rapidly in the past ten years, there are still some shortcomings and deficiencies, such as reliability and stability can not fully meet the requirements; The defect is serious, and it is necessary to find a suitable solution; the cost of equipment is relatively high, which limits the further promotion and application of SLM technology; the size of the parts that can be prepared is limited, and the current process for preparing large-size parts is not yet mature; the process parameters are more complicated. The existing technology is not deep enough to study the mechanism of SLM, and it takes a long time to explore. Contents of the invention [0003] The purpose of the present invention is to design a novel met...
