Drawing-off device for an extrusion press with an antiparallel crank gearing for the lifting and lowering movement

摘要

Anti-parallel crank mechanism has a mechanical connection between a carriage (3) and a pulling device (1) formed by a main arm (11) and a coupler (14). The main arm and the coupler are positioned on the carriage on one side and on the pulling device on the other side so that the main arm and the coupler are located in an anti-parallel position to each other. The bearings (12, 15) for the main arm and the coupler are arranged so that during lifting and lowering of the pulling device a curve is followed between the lifted and lowered positions. Preferred Features: The lifting drive (7) is positioned on the carriage on one side close to a rail and on the pulling device on the other side.
