Abstract

The invention provides a metal wire material additive equipment based on an alternating magnetic field, which at least includes a numerical control device, a substrate, and a deposition head. Both the substrate and the deposition head are installed on the numerical control device, and the substrate is located on the deposition head. Below, the deposition head includes a shielding shell and a wire wheel installed on the shielding shell, the wire is wound on the wire wheel, and a wire feed wheel, a ceramic guide tube, an alternating magnetic field coil and a shielding gas are arranged inside the shielding shell The top of the shielding shell has a wire inlet, the wire feed wheel is installed below the wire inlet, the ceramic guide tube is vertically fixed below the wire feed wheel, and the alternating magnetic field coil is wound on the ceramic guide on the outer wall of the lower part of the tube. At the same time, the present invention also provides a material additive method based on the above material additive equipment. The present invention solves the existing problems of difficult preparation of metal powder, high price, and low energy efficiency of laser light sources.

Description

technical field [0001] The invention relates to the technical field of metal additive manufacturing, in particular to a metal wire additive manufacturing method and equipment based on an alternating magnetic field. Background technique [0002] Additive manufacturing technology, also known as 3D printing technology, has gained more and more attention in recent years. Additive manufacturing is based on three-dimensional CAD design data, using discrete materials (liquid, powder, wire, sheet, plate, block, etc.) It is a multi-disciplinary advanced manufacturing technology that integrates mechanical, optical, electrical, computer, control and other technologies to manufacture physical parts. Compared with the traditional manufacturing process, additive manufacturing technology can directly use CAD data to directly manufacture any complex structure in space without molds and tools, and has a wide range of forming materials, which can quickly transform designs into high-performanc...
