Abstract

The invention provides an extruding method for a two-dimension function-variation continuous variable-cross-section profile, and aims at solving the forming problem of a continuous variable-cross-section member showing function variation along the length direction. By coordinating the rapid response cooperation motion among a bearing segmented die, a molding segmented die and an extrusion rod, controllable continuous variable-cross-section precise molding for a member which possesses a relatively large length-diameter ratio and has the cross section shape relatively substantially changing along the profile length direction is realized.

Description

technical field

[0001] The invention relates to a metal profile processing method, in particular to a two-dimensional function variable continuous variable section profile extrusion method. Background technique

[0002] With the increasing demand for lightweight industrial equipment, aluminum alloys and magnesium alloys have been widely used in the transportation industry, electronics industry, medical field, military industry and aerospace fields in recent years. However, if the light metal material is directly replaced with the steel part, the low comprehensive strength and stiffness of the light metal material will be difficult to meet the requirements of the original part, which requires a large plastic deformation to increase the strength of the light metal material , and high-efficiency and low-energy-consuming part structure forming process to ensure reliable performance and controllable cost of light metal weapon components. Especially for parts with a large long-di...
