Metal cladding forming device and method using gaps and grooves to constrain part layer thickness and layer width

Abstract

The invention relates to a precise forming method, in particular to a metal cladding forming device and a method restraining layer thickness and layer width of a spare part with a gap and grooves. The precision and efficiency of the formed spare part can be ensured, the possibility of mass production of the micro mechanical spare part is effectively increased, and the processing cost is lowered. The method comprises the steps of: I: adjusting a distance between a fixed feeder and a substrate according to the layer thickness of the spare part, selecting the groove for use according to the layer width of the spare part, and filling the rest unused grooves with screws, II: coating the gap between the fixed feeder and the substrate with molten metal through a feeding port of the fixed feeder to form a uniform cladding layer, and III: coating the substrate with the molten metal continuously, and allowing the substrate to move in three directions to form the required spare part. According to the invention, the layer thickness and the layer width of the spare part are restrained by the gap and the grooves, the forming precision can be improved, the forming of the spare part is accelerated, the product quality is excellent, and the improvement of the quality and forming efficiency of a product is facilitated.

Description

technical field [0001] The invention relates to the field of precision forming, in particular to a metal cladding forming device and method. Background technique [0002] Metal cladding is a new type of coating technology, involving multi-disciplinary high-tech such as optics, mechanics, electricity, materials, detection and control, etc. It is a new processing and manufacturing technology that cannot be completed by traditional manufacturing methods, and it is a national key support And promote a high technology. At present, many scientific research institutes at home and abroad, such as Northwestern Polytechnical University, Huazhong University of Science and Technology, MicroFab commercial company in the United States, University of Toronto in Canada, etc., focus on the research of metal cladding forming technology on laser cladding mechanism, driving mode selection and metal cladding technology. The thermal state analysis of the cladding process and other aspects, but t...
