摘要
通过数值模拟方法对瓶式容器热旋压成形过程中不同因素对旋压力的影响进行研究。研究表明,瓶式容器热旋压成形中,随着温度的升高,旋压力逐渐降低,随着进给比的增大,旋压力逐渐升高;各道次内径向旋压力与总旋压力大小非常接近,切向旋压力<轴向旋压力<径向旋压力;随着旋压道次的增多,旋压力逐渐增大。
The influences of different processing parameters on the spining force of hot neck-spining formation of the bottle pressure vessel has been analyzed by numerical simulation. The results show that during the hot neck-spining forming process of the bottle pressure vessel, the spining force decreases with the increasing of temperature and increases with the increasing of feed ratio;Radial spining force in every pass is very close to the total spining force, and the relationship among the three components of spining force is: tangential spining force < axial spining force < radial spining force;The spining force increases gradually with the increasing of spinning pass.
