doi:10.3901/JME.2020.04.049

Abstract

Abstract: As the main container of high pressure gas, high pressure cylinder is widely used in petrochemical，metallurgy，machinery，transportation，mining，medicine and other industries and daily life. Drawing process is an important method for making High pressure Gas cylinders. The roller die drawing force of high pressure cylinder is one of the important parameters in pipe drawing process. In this paper，the drawing process of gas cylinder roller die is analyzed by plastic mechanics，the geometric model and mechanic model of the gas cylinder during the roller die drawing process are established，and the calculation formulas of the roller die drawing force is deduced. Based on The Mechanical properties of gas cylinder material obtained by thermal tension test of Steel for cylinders 34CrMo4，the numerical analysis model 5-roller die drawing of gas cylinder is established which is compared with the result of theoretical model. The results of the simulation are in good agreement with the calculated results of theoretical model. Therefore，the theoretical calculation model and the numerical model can provide important references for the roller die drawing process of gas cylinders.
