摘要

高压电气产品中

活塞杆和接头类零件属于关键零件

且应用较多

这类零件属于长轴类带法兰件

目前

采用的加工方式是用棒料直接加工成形

材料利用率低

工艺性差。笔者分析了活塞杆和接头类零件的形状特点

认为采用双肘杆镦锻工艺制坯

解决了材料浪费问题

降低了零件制造成本

提高了零件抗拉强度。阐述了双肘杆镦锻模具设计、成形工艺、热处理工艺等方面的内容。

Abstract

Piston rods and connector-type parts are critical parts in high-voltage electrical products.These parts belong to’long axis with flange’ class

and the existing shape-forming process is of directly machining bar with low material utilization and efficiency.In this paper

shape features of the piston rods and connector-type parts are analyzed

and double elbow-bar upsetting technique is suggested to save material

shorten processing time

reduce manufacturing costs and increase tensile intensity of the parts.Moreover

the design of double elbow-bar upsetting mold

the molding process

and the heat treatment are discussed.
