CONFORM铝连续挤压机主轴系统研究

A Research on the Mandrel System of CONFORM Aluminum Extrusion Press

本文分析了CONFORM连续挤压机主轴系统工作时的受力情况。主轴受热伸长时在主轴系统产生很大的轴向力，对设备性能影响非常大。设计出一种新型联轴器联接主轴，此联轴器在受很小轴向力的作用时，允许被联接轴作轴向游动，基本消除了轴向力及其对设备性能的影响。此项设计改进已应用于LJ300连续挤压机，效果十分理想。

This paper analyses in details the acting forces on the mandrel system of CONFORM extrusion press during working period and introduces a new type of mandrel coupling which is designed by author in order to eliminate mandrel axial force and has successfully applied to a LJ300 continuous extrusion press.
