摘要

电子管底座内腔结构复杂

传统机械、电解加工生产效率低

性能差。针对制件特殊结构

经过工艺方案对比分析

选用管形坯料一次冷挤压成形工艺。根据计算的毛坯形状尺寸、变形程度、挤压力

进行了成形设备的选择、凹凸模尺寸设计和模具结构设计。

Abstract

The base tube is made of oxygen-free copper with a complex inner cavity

so traditional machining and electrolytic machining can’t meet the requirements of efficiency and excellent product quality.According to the special structure

single pass cold extrusion forming with a hollow tube was adopted after the comparative analysis.Based on calculating the dimensional size

deformation rate and extruding force

the suitable forming equipment

the die size design and die structure design were conducted.
