Problems solved by technology

[0006] Among the laser 3D forming methods reported above, they mainly focus on the powder bed laser processing, or although it is a synchronous powder feeding laser forming method, it belongs to the optical powder feeding coaxial powder feeding, the material utilization rate is low, and the work efficiency is not high.
At the same time, in terms of laser composite forming processing, it is limited to the composite forming method of laser cladding and selective laser sintering technology fusion technology and the forming method of laser additive manufacturing and subtractive manufacturing. Low density and unsatisfactory surface precision

Abstract

The invention discloses a 3D laser forming device and a method thereof for additive and equal material composite metals. The device comprises a base and a host crossbeam, and the host beam and the base are fixedly connected by columns arranged on both sides. It also includes The pan-tilt base is arranged on the base and can rotate relative to it. The pan-tilt base is provided with a workbench that can move laterally relative to it for placing workpieces. A material processing mechanism that moves laterally, and an equal material processing mechanism is provided on one side of the pan-tilt base. The device of the present invention is based on the composite forming method of 3D laser additive manufacturing and equal-material plastic processing of metal powder materials with coaxial coaxial powder feeding in the light, which avoids serious powder particles and sparks splashing during the processing process and low density of the final product. insufficient.

Description

technical field [0001] The invention relates to a 3D laser forming device and a method thereof, in particular to a 3D laser forming device and a method thereof for additive and equal material composite metal. Background technique [0002] Metal 3D laser processing technology is an emerging science and technology that is developing rapidly today. This technology combines selective laser sintering technology and laser cladding technology. Based on the forming idea of ​​"discrete + accumulation", it scans and accumulates materials layer by layer according to the layered section contour trajectory of the part, and finally forms a three-dimensional solid part or only needs a small amount of processing. Processed near-shaped parts. It has good flexibility (no special tools, molds and fixtures are required), fast processing speed, high material utilization rate, basically no limit to the complexity of parts, and can realize the forming of high melting point difficult-to-process ma...
