半轴套管挤压工艺实验研究

Experimental Research On Extrusion for Axle Shaft Sleeve

针对半轴套管的两种结构特点,在分析了国内外近年来所采用的各种成形工艺的基础上,分别开发了用镦粗-反挤压和扩径-正挤压两道复合工序相结合成形分体式半轴套管和用两次复合镦挤的方法成形整体式半轴套管的两种热挤压成形新工艺,通过物理模拟实验证明了成形工艺的可行性、实用性。

Aiming at the two structural features of axle shaft sleeve on the basis of analyzing various forming technologies applied in domestic and overseas in recent years, two new hot extrusion forming technology of axle shaft sleeve are worked out. i.e. one applies two steps composite technology of upsetting-backward extrusion and expanding-forward extrusion forming divided axle shaft sleeve, other is dual upset extruding forming totally axle shaft sleeve. The feasibility and practicability of theirs technology have been proved through physical simulative experiments.
