Patent DE-4324619-A1 (DE)
Title: Device for the releasable connection of feedbar parts in a transfer press
Inventor: BLAU PETER
IPC: B21D43/05
Filed: 1993-07-22
Abstract: In known devices, the feedbar parts are held together by pressing flange surfaces at their ends onto one another. The flange surfaces are designed as flat surfaces which extend parallel to the stroke movement over the width of or part of the end faces. After the release of the clamping means, the extendable feedbar parts are raised together with the stroke movement of the sliding table by a distance larger than the width of the flange surfaces. In the process, the flange surfaces slide upon one another without play and this can lead to the jamming of the feedbar parts. By means of the new device, tilting or jamming of the feedbar parts is prevented and the requirements as regards positional accuracy during the lowering of the sliding tables are reduced. In the new device, the flange surfaces (24, 25) are designed to be oblique relative to the axis of motion of the vertical stroke movement of the feedbars, the angle of inclination of the flange surfaces (24, 25) being chosen in such a way that a free space is formed at the division between the flange surfaces (24, 25) as the exchangeable feedbar parts (1) are raised. <IMAGE>
