Abstract

The invention discloses a forming device of an ultrahigh-pressure static liquid extrusion magnesium alloy pipe and a forming process thereof. The forming device totally adopts a horizontal structure, and comprises a supercharging cylinder, an extruding cylinder, a first pressing medium exchange disc, a second pressing medium exchange disc, a third pressing medium exchange disc, an extruding mold, a first heating sleeve, a second heating sleeve and a high-pressure hydraulic pump with an extruding shaft. The supercharging cylinder, the extruding cylinder, the pressing medium exchange discs, the mold and the high-pressure hydraulic pump are all fixed between a movable beam and a fixed beam; and the movable beam and the fixed beam are connected through a tension column. The supercharging cylinder and the extruding cylinder are arranged in parallel, and are positioned in the same one horizontal plane. The extruding shaft is positioned in the supercharging cylinder; a blank is positioned in the extruding cylinder; the travel of the extruding cylinder and the size of the blank both can be increased; the magnesium alloy pipe with a longer length can be obtained by static liquid extrusion machining through the forming process on the forming device; and the production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of metal forming, and in particular relates to a forming device and a forming process for an ultra-high pressure hydrostatic extruded magnesium alloy pipe. Background technique [0002] Magnesium alloy has the advantages of high specific stiffness, specific strength, good heat dissipation, excellent machining performance, good electromagnetic shielding effect, and easy recycling. It has gradually emerged in the fields of national defense, automobiles, and electronic communication equipment, and has great potential for future development. Magnesium alloy pipes are one of the most widely used forms of magnesium alloys, and it is of great significance to develop magnesium alloy pipes with better mechanical properties. [0003] The common method of processing magnesium alloy parts is cutting, but cutting consumes raw materials and the utilization rate of materials is low; some parts with complex shapes can be ma...
