#CMT# #/CMT# The press has transform-cylindrical piston arrangements operated on an upper press table (4) and a lower press table (5), where the cylindrical piston arrangements are supported by closed press frames of a press rack. Upper tool carriers (7a, 7b) and lower tool carriers (8a, 8b) are provided for respective upper and lower tools, where position of the tool carriers is adjusted and locked transverse to a press longitudinal direction. The tool carriers are arranged on both sides of a central support rack (14) of the tables so that forces are initiated by opposite sides of the support rack. #CMT#USE : #/CMT# Press e.g. hydraulic bending press and transforming press, for bending longitudinal edges of a sheet during production of a longitudinal seam-welded pipe (claimed). #CMT#ADVANTAGE : #/CMT# The tool carriers are arranged on the sides of the central support rack of the tables so that the forces are initiated by the opposite sides of the support rack, thus preventing high forces admitted by the frames, and hence facilitating a stable and compact structure to the press in a simple and functional manner, and adjusting the press in different conditions. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross section of a hydraulic bending press. 4 : Upper press table 5 : Lower press table 7a, 7b : upper tool carriers 8a, 8b : Lower tool carriers 14 : Support rack. |
