摘要
A deep-drawing tool for deep drawing blanks which are punched out of sheet material that is painted or coated with film material, in order to obtain flangeless molded blanks, includes a drawing bell, a drawing core, a blank holder, a force transmission device, a drawing cushion for applying a spring force to the blank holder by the force transmission device, and a drive which, after the drawing bell reaches a predetermined position in downward movement thereof, drives the force transmission device to perform a movement which precedes movement of the drawing bell.
