摘要
根据零件成形特点,分析了成形前的坯料加工工艺,找出了坯料加工与挤压成形的切入点,设计了正挤缩径与反挤成形组合工艺装置,综述了缩径挤压模具的设计要点、模具结构、工作原理及实际应用效果。
According to the forming characteristics the billet preparation before forming is analyzed and extrusion is taken as a procedure. The combined die of forward extrusion necking and backward extrusion is designed. The main points of die de sign, die structure, working principle and actual application effect are introduced.
