Abstract

The invention discloses a device and a method for utilizing molten metal deposition to form a thin wall structural member. The device comprises a metal wire and a wire feeding roller, a nozzle conducts x-y planar motion according to the section outline information of the thin wall structural member, meanwhile extrudes molten metal and controls the molten metal flow to enable the molten metal to be evenly deposited on a substrate, and the molten metal is quickly cooled to form the section outline of a thin wall part. After one layer is formed, the substrate descends for the height of a section layer to conduct deposition of the next layer, and the process is circulated to finally obtain a product prototype of the metal thin wall structural member. The device and method has the advantages of being high in machining flexibility, stable in product quality, small in heat affected zone, small in workpiece heat deformation and small in follow-up machining quantity, effectively improves manufacturing efficiency and performance of the thin wall structural member, greatly reduces manufacture cost and improves the batch production probability through the molten metal deposition method.

Description

technical field [0001] The invention relates to the field of rapid prototyping of metal thin-walled structural parts, in particular to a device and method for manufacturing thin-walled structural parts by using a metal fusion deposition method (FDM). Background technique [0002] Rapid prototyping technology is a high-tech emerging in the late 1980s, which integrates CAD / CAM, numerical control and material science technologies. The basic idea is: using layered software, the three-dimensional solid model established by CAD is divided into a series of thin section layers, and the forming system adopts bonding (sintering), polymerization or chemical reaction according to the two-dimensional data formed by each section layer. By means of such means as liquid (or bonded solid) materials are selectively solidified layer by layer, so as to quickly accumulate solid models. At present, more mature rapid prototyping processes include: stereolithography (SL), laminated entity manufact...
