Abstract (en)

[origin: EP0083577A1] 1. Holding device for the pipe end pieces in a hydraulic pipe end press, which has a C-shaped frame (1) in which the pipe end is held between the upper and the lower matrix half (4, 5) whereby the lower matrix half (5) is held in the pressing table and the upper matrix half (4) is held in the cross piece and the cross piece is movable toward the pressing table with the aid of at least one piston/cylinder unit (6, 7) applying the holding force, characterized by an elbow lever (9, 13, 10, 14) transferring the holding force in its extended position, the one end (9, 10) of which is articulated on the piston (11, 12) of the piston/cylinder unit (6, 7) and the other end of which (13, 14) is articulatedly connected with the cross piece (3) and the elbow joint (15, 16) of which is connected with a further power drive (17) to bend and extend the elbow lever (9, 13, 10, 14).
