Forming tool with ring-shaped bottom die - has hydraulically movable servo element to apply external pressure to die for elastic deformation

摘要

The forming tool has a ring-shaped bottom die (1), which deforms elastically. A movable controllable servo element (3), with an internal cone, applies an external pressure to the die, which has an external cone. The servo-element is moved by hydraulic or pneumatic pressure. The bottom die can be extracted, after cover (6) and intake sleeve (8) have been removed. USE/ADVANTAGE - Ring-shaped bottom die is used on hydraulic forming tool and has continuously adjustable internal dimensions.
