#CMT# #/CMT# The tool has a hybrid press plant or a press line with a lower tool part (10), to which a metal sheet holding device (18) e.g. circular holder, is attached. The metal sheet holding device is movably arranged with respect to a molded part (17) in a pulling direction. The pulling direction corresponds with a relative motion direction, in which an upper tool part (9) and the lower tool part are moved against each other. A tensioning device (23) includes a tension member (25) for connecting the upper tool part with the metal sheet holding device. #CMT# : #/CMT# An independent claim is also included for a drawing press comprising a draw tool and a mobile stored and propelled tappet. #CMT#USE : #/CMT# Draw tool for a body-drawing press stage of a drawing press i.e. transfer molding press (claimed) that is utilized for molding large plates and for assembling a body part of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The tensioning device includes the tension member for connecting the upper tool part with the metal sheet holding device, thus producing larger or smaller stresses in order to control sliding of an edge of metal sheet between the holder and the counter-abutment surface, and hence precisely adjusting the force arising due to the short force path. The tool avoids deformations of the press, the press frame, the piston rod, the tappet of the press table and other components. The sheet holder and the respective tool part implement a common pulling movement, such that the holder and tool part do not move relatively to each other during the pulling process, thus applying holding force without performing any mechanical work. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a draw tool of a drawing press. 9 : Upper tool part 10 : Lower tool parts 17 : Molded part 18 : Metal sheet holding device 23 : Tensioning device 25 : Tension member. |
