Impact extrusion technology in our country's application and progress
[Abstract] In our country, the impact extrusion technology obtained more and more applications, has the many type non-ferrous metals and the ferrous metal available impact extrusion method carries on the production, the impact extrusion components complex degree also unceasingly enhances. This article discussed impact extrusion Xu Yong the distortion degree, lubrication selection, cold drop forging application and stainless outline extrusion each question. As a result of the mold structure's rationalization as well as the mold material's development, the swaging die set life has the unceasing enhancement. The impact extrusion is in machine manufacture's one metal shaping few, does not have cuts the new craft. Carries on the production with the impact extrusion method to be possible to raise the labor productivity, the frugal raw material, to be possible large scale the quality assurance, produces Cheng Muyi to obtain the remarkable drop. Since recent years, the various industries advanced countries extremely have taken seriously to the impact extrusion development, this new technology obtained the widespread application. In our country, the pre-liberation impact extrusion technology falls behind extremely; After the liberation, this new craft obtained the development. Since recent years, the impact extrusion obtained more and more applications in various departments. The following on the impact extrusion material, the distortion working procedure as well as swaging die set each aspect carries on the discussion. First, the impact extrusion with the material in our country, the pure aluminum, against tempts the aluminum, to hammer the aluminum, the duralumin, the red copper, the oxygen-free copper, the copper content in 62% above brasses in the 50s should。
