Title Study on the design of magnesium alloy Extrusion die

Abstract

With the rapid development of China's defense industry and technology for weapons of lightweight and economy have higher requirements, the same requirements for weapons material increases.Magnesium alloy for its low density, high strength and good thermal performance, plus it is almost "inexhaustible" the great advantage,By the countries defense industry attention, especially in the huge production of magnesium alloys, we are gradually upgrading their level of utilization.Magnesium alloy at home and abroad to prove, a better use of its hydrostatic extrusion technology to give than ordinary extrusion, casting magnesium alloy processing methods such as product performance, so we have the equipment and its magnesium alloy extrusion, etc. Research and Design use imminent.

In the past ten years time, domestic and foreign research scholars about the light alloy by hydrostatic extrusion die design and research have made a lot of work, and has made significant achievements,On this basis, the paper summarizes the study,Using Deform-3D finite element software, the use of theoretical calculations, the reasonableness of the selection of a different mold angle, bearing length billet temperature, extrusion speed, mold temperature and to consider at operating temperatures of AZ80 magnesium alloy by hydrostatic extrusion Numerical simulation of pressure,Effect obtained the conditions of extrusion pressure, temperature, stress in the blanks themselves design requirements, and under practical conditions taking into account the conditions selected combination. The results provide a strong basis for the design of AZ80 magnesium alloy profiles hydrostatic extrusion process parameters optimization design.
