【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。更多还原

【Abstract】 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.更多还原
