|
Thin-wall cone workpieces of titanium alloys have been wildly used in important fields,such as aeronautics,aerospace and weapon industries.The existing processing methods have been unable to meet the requirements of precision parts.Power spinning heated by flame,a new technique of metal plastic forming,is recognized as an effective method to produce big thin-wall cone workpiece.A warm shear spinning process of TC4 titanium alloy cone workpiece was studied.The forming status of TC4 titanium alloy under different conditions was presented.The formation mechanism of quality defects was analyzed.The warm shear spinning process of TC4 titanium alloy cone workpiece was determined,which made a base for research on process of mass production of TC4 titanium alloy cone workpiece by warm shear spinning method.
