目前，国内生产高压容器如氧气瓶，蓄能器头部收回过程中还没有应用液压传动与控制系统。现在的收口加工，是利用火焰或高频电磁加热使收口段成红热的塑性状态，然后用特制的刀具（一种成型别板）绕固定轴摆动，刀头挤压气瓶表面，使之收回成所需的形状。这种利用金属的热塑流 At present, the domestic production of high pressure containers such as oxygen bottles, accumulator head recovery process has not been applied hydraulic transmission and control system. Now shut processing, is the use of flame or high-frequency electromagnetic heating to make the mouth section into the red hot plastic state, and then with a special tool (a molding plate) around the fixed axis swing, the blade squeeze the surface of the cylinder to recover into The desired shape. This thermoplastic flow of metal
