Design and Analysis of Double-head Uncoiling Machine for Cold Rolling
摘要
Abstract
In order to solve the problems of operational safety and low work efficiency of manual coiling in cold rolling,a new type of uncoiling machine with double heads is designed,which is composed of guidance mechanism,support mechanism,expansion and tightening fixing mechanism,and uncoiling machine body.In order to replace manual reeling,a guiding mechanism is installed on the side of the uncoiler,and the reeling can be automatically completed by adjusting the guide straight plate.In view of the metal fatigue of the spindle caused by long-term compressive stress,a support mechanism is installed on the lower side of the spindle,which can transfer some compressive stress of the steel coil to improve the working stability of the spindle.To improve the efficiency,the fixed mechanisms are installed on both sides of the support spindle,and synchronization of loading and uncoiling could be realized through linkage control.The model of each mechanism of the uncoiler is established by using CATIA.The motion interference checking upon the virtual uncoiler is carried out.The simulation results show that the uncoiler movement is interference-free.The static analysis of the uncoiling process is carried out,and the stress cloud diagram shows that the maximum stress of the fixed mechanism is 830.837 kPa,which did not exceed the allowable stress of the material.关键词
