Abstract

In order to improve the formability of challenging materials, the innovative flame-heating integration into a spinning machine is proposed to apply new processing strategies for flame-assisted die-less shear and multi-pass metal spinning. The device mainly includes measurement system and control system. The calculating function of control system is designed to adjust the forming temperature according to the feedback of measurement system. TC4 and TA2 are used for shear spinning and multi-pass spinning to verify the feasibility and reliability of the system with the forming temperature 450 and 850 °C respectively. The temperature change during the process of spinning is recorded once a second by temperature sensors. Then the absolute values of mean relative deviations under two conditions are less than 5% by comparing measurement temperatures and preset temperatures. Furthermore, the result shows that the forming accuracy by adopting the system under two conditions is acceptable. [ABSTRACT FROM AUTHOR]
