STRETCH-FORMING MACHINE AND METHOD |
摘要 |
A stretch-forming machine of the type wherein a pair of opposed curving jaw assemblies grip opposite end edge portions of a metal sheet for initially stretching the metal sheet into a yield state and forming the metal sheet into a predetermined curved configuration. The pivot and the actuator cooperate to stretch the outer corners of the metal sheet while substantially minimizing elongation along the centerline of the metal sheet.
