Abstract

The invention belongs to the field of industrial manufacturing, and provides a novel stir friction additive manufacturing machine. The novel stir friction additive manufacturing machine comprises a powder feeding system, a grinding system, a welding system, a powder outlet and a striker plate. The machine is mainly used for the field of industrial additive manufacturing, the core principle adoptsmechanical friction, and then the cost is low compared with laser additive manufacturing. In the additive manufacturing process, it can be guaranteed that no gap exists in contact of an additive layerand the workpiece surface, the mechanical property of workpieces is greatly improved, and the stability of the workpieces is greatly improved. Therefore, the workpieces obtained after additive manufacturing is uniform in stress in the use process, and the service life is prolonged. Accordingly, the advantages of the mechanics and mechanical design are fully combined, and then the additive manufacturing process is simplified, and the cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of engineering manufacturing, and in particular relates to a novel friction stir additive manufacturing machine. Background technique [0002] The development of additive manufacturing technology has promoted the progress of engineering manufacturing technology. The manufacturing heat source mainly comes from lasers, electron beams, etc. During the manufacturing process, material melting will cause problems such as thermal cracks. Therefore, based on the principle of additive manufacturing , developed a new technology for additive manufacturing based on mechanical stir friction, which can use frictional heat to make metal powder in a thermoplastic flow state, but the material is still below the melting point, thereby avoiding problems such as thermally induced cracks due to material melting. Contents of the invention [0003] The problem to be solved by the present invention is how to design a novel fricti...
