Additive, equal material, subtractive composite metal 3D laser forming device and method

Abstract

The invention discloses a 3D laser forming device and method for composite metal with additive, equal and subtractive materials. The device includes a base and a beam of a main machine, and the beam of the main machine and the base are fixedly connected by columns arranged on both sides. It also includes a pan-tilt base that 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. An additive processing mechanism and a material subtractive processing mechanism for the beam to move up and down and laterally; one side of the platform base is provided with an equal material processing mechanism. The invention can realize the composite forming method of 3D laser additive manufacturing, isomaterial plastic processing and material subtractive processing, the density of processed parts is increased, and the comprehensive performance of parts is improved.

Description

Technical field[0001]The present invention relates to a 3D laser forming device and a method thereof, in particular to a 3D laser forming device and a method for additive, equivalent and subtractive composite metal.Background technique[0002]Metal 3D laser processing technology is a rapidly developing emerging science and technology. This technology combines selective laser sintering technology and laser cladding technology, based on the "discrete + accumulation" forming idea, scans the stacked materials layer by layer according to the layered cross-sectional contour trajectory of the part, and finally forms a three-dimensional solid part or only a small amount Processed near-shaped parts. It has significant advantages such as good flexibility (no need for special tools, molds and fixtures), fast processing speed, high material utilization, basically no limit to the complexity of parts, and can realize the formation of high melting point and difficult to process materials. It is now ...

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 accuracy
