汽车法兰轴管热挤压毛坯常见缺陷及模具设计

Common Defects of Automobile Flange Axle Casing Hot Extruding Blanks and the Design of Hot Extruding Die

介绍了汽车法兰轴管(亦称半轴套管)毛坯的热挤压成形工艺及3工位热挤压模具概况,讨论分析了汽车法兰轴管(毛坯)最常见缺陷的成因及消除方法,重点介绍了荒型模(Ⅰ工位模具)凸模(冲头)结构对缺陷形成的作用和改进措施。

This paper introduces the genneral situations of automobile flange axle casing （half-shaft casing）blanks＇ hot extruding forming processes and three-position forming dies. It discusses and analyses common defect reasons of automobile flange axle casing （blanks）and methods for eliminating. The defect effects of forming die （I position die）punch structure and the measures for improvement are introduced.
