Method for manufacturing bush, involves forging bushing blank with end contour nearer outer and inner contour, where bushing blank is stretched for end contour specific formation of inner contour and finishes outer contour

摘要

The method involves forging a bushing blank with end contour nearer outer and inner contour (2,3). The bushing blank is stretched for end contour specific formation of the inner contour and finishes the outer contour. The inner contour is formed by the longitudinal extension of the bush, approximately a small end bushing (1).
