微型内螺纹铜管（MIGCT）在工业中得到广泛应用。为了克服MIGCT在制造阶梯管时刚性和强度较弱的问题，与径向锻造工艺进行比较后，选择旋锻工艺。分析了旋锻的工作原理。设计了一种工件送料和夹紧分别由气缸和手指气缸驱动的旋锻机。实验表明，在旋锻过程中，MIGCT 与锻模一起从动旋转。对从机轮换的原因进行了理论分析。进行了实验来验证理论分析。此外，还讨论了推力和夹紧力对转速的影响。随着锁模力的增加，MIGCT的转速以恒定比例逐渐减小。然而，推力对管旋转速度影响较小。总的来说，发现MIGCT的最佳转速有利于阶梯管的制造。
Miniature inner grooved copper tube (MIGCT) is widely applied in industries. To overcome the weak rigidity and strength of MIGCT during stepped tubes manufacturing, rotary swaging process was selected after comparing with radial forging process. The working principle of the rotary swaging was analyzed. A rotary swaging machine, whose workpiece feeding and clamping was respectively driven by an air cylinder and a finger cylinder, was designed. Experiments indicate that the MIGCT was slave rotating with forging dies during rotary swaging. Theoretical analysis was done to investigate the reason of the slave rotation. Experiments were carried out to verify the theoretical analysis. Furthermore, the influences of push force and clamping force on rotation speed were discussed. With the increase of clamping force, the rotation speed of MIGCT decreases gradually in a constant ratio. However, the push force influences the tube rotation speed slightly. In general, it found that an optimal rotation speed of MIGCT is beneficial to the manufacture of the stepped tube.
