Abstract

The invention relates to an electron beam additive, and provides an electron beam fuse wire additive manufacturing method which comprises the following steps: firstly, dividing a manufactured printed part into a plurality of sediment layers by using layering processing software, performing fuse wire sedimentation along a sedimentation route of each sediment layer, and feeding fuse wires by using at least two fuse wire feeding machines corresponding to the sedimentation route of each sediment layer, thereby feeding the fuse wire corresponding to each sedimentation route from the front part of a furnace hearth. According to the electron beam fuse wire additive manufacturing method, a wire material generated from a fuse wire feeding machine corresponding to each sedimentation route is positioned in front of the sedimentation route, so that the radiation of the furnace hearth to the wire material can be relatively large, the wire material can be relatively sufficiently molten, the quality of each molded sediment layer can be effectively ensured, and the sediment layer can be relatively high in smoothness degree.

Description

technical field [0001] The invention relates to electron beam additive materials, in particular to an electron beam fuse additive manufacturing method. Background technique [0002] There are currently two methods of electron beam additive manufacturing: electron beam melting powder technology (EBM) and electron beam fuse forming technology (EBF). 3 ). Electron beam melting powder technology uses metal powder as raw material, which has the disadvantages of difficulty in manufacturing the required metal powder, high cost of use, low molding efficiency and difficult storage of metal powder. Electron beam fuse forming can achieve high-efficiency deposition forming while ensuring that the quality of the printed parts can reach the forging level. This technology has the characteristics of no reflection in the process of melting the wire by the heat source, fast forming speed, high material utilization rate, and high energy conversion efficiency. It can be used in Rapid prototyp...
