阻焊式双工位金属叠层制造关键工艺研究
Key techniques of rapid manufacturing for metal parts based on resistance welding double-staged LOM
摘要
Abstract
This paper presents a study of three main technologies of metallic laminated manufacturing, that is, laser cutting, resistance welding and material movement control. Conducted 302 stainless steel sheets of 0. 1 mm in thickness as the laser cutting material, the statistical analysis of the experimental results show that a perfect cutting quality achieved under laser power is 85 W and cutting speed is 190 mtn/min. By contrasting experiment with welding current combined with welding quality and microstructure morphology, a good welding quality achieved under the welding current is 2 700 A. The accuracy of the welding is obtained by the specific design of the machine and the speed of material movement. Based on the research above, rapid laminated manufacturing for metal parts is conducted. As a result the plastic rapid injection mold shows its strength to be more than 600 MPa. The surface of plastic product injected according to the mold reaches the standard in dimensional accuracy and surface finish.关键词
