Metal material melt coating forming device and method

Abstract

The invention discloses a metal material melt coating forming device and a metal material melt coating forming method. The device comprises a metal smelting unit, and further comprises a pneumatic driving device, a melt coating head, a laser surface auxiliary remelting device, a three-dimensional forming platform and an atmosphere protection device, wherein the pneumatic driving device is connected with the metal smelting unit through a pipeline; the melt coating head is connected to the lower end of the metal smelting unit; the three-dimensional forming platform is arranged below the melt coating head; the laser surface auxiliary remelting device is arranged on one side of the three-dimensional forming platform; and the metal smelting unit, the melt coating head, the laser surface auxiliary remelting device and the three-dimensional forming platform are arranged on the atmosphere protection device. The melt coating forming device can be used for additive manufacturing of an efficient, high-quality and low-cost metal material part.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to a melting coating forming device and method, in particular to a metal material melting coating forming device and method. Background technique [0002] Additive manufacturing technology (also known as "3D printing") is rapidly changing traditional production and lifestyles. Its core idea is to discretize three-dimensional parts in two dimensions to form layered data. According to the layering of the three-dimensional CAD model of the part Data, the discrete forming materials are gradually combined to form layered cross-sections, and then piled up layer by layer to form solid parts. The parts can be directly manufactured without molds, which can greatly reduce costs and shorten the development cycle. At present, relatively mature metal parts additive manufacturing technologies mainly include laser rapid prototyping, such as selective laser melting (Selective Laser Malting, SLM), d...
