摘　　要：针对JX1030半轴套管体的结构特点,在分析国内外近年来采用的各种成形工艺的基础上,开发了在常规设备条件下,以圆棒材为坯料,用镦粗-反挤压和扩径-正挤压两道复合工序相结合的热挤压成形新工艺。通过物理模拟实验证明了该变形工艺的可行性、实用性。Aiming at the structural characteristic of JX1030 vehicle back-bridge axle shaft sleeve and through the analysis on various forming technologies applied in domestic and overseas in recent years, a new hot extrusion forming technology was developed which applied the general equipment and rod material. It applied 2 steps composite technology of upsetting-backward extrusion and expanding-forward extrusion. The feasibility and practicability of this technology were proved through the physical simulative experiments.
