| Abstract: | Axial ejector mechanism is usually used in precision cold extrusion die for stripping of parts.The resistance is large due to the forming springback of thin walled parts like a concave slide shoe for ball,thus resulting in part deformation or die damage.In order to solve the problem,rotary of cores is arranged to act before ejector device works for eliminating the microscopic mechanical binding force between the die core and inner surface of the slide shoe.In this paper,the principle of rotary stripping was... |
