2219铝合金三角形异型管材的研制

Development of 2219 aluminum alloy triangular shaped pipe

结合2219铝合金特性和三角形异型管材的结构特点,采用穿孔挤压针的方式挤压出无缝异型管。针对该材料的生产难点,从模具设计、挤压工装、挤压工艺、热处理工艺、拉伸工艺等方面对三角形异型管材的生产进行了分析和研究,成功生产出2219铝合金三角形异型管材。

Combined with the characteristics of 2219 aluminum alloy and the structural characteristics of triangular shaped pipe,the seamless shaped pipe is extruded by the way of perforated extrusion needle.In view of the production difficulties of this material,the production of triangular shaped pipe was analyzed and studied from the aspects of mold design,extrusion tooling,extrusion process,heat treatment process and drawing process,and the triangular shaped pipe of 2219 aluminum alloy was successfully produced.
