摘要： A device for processing a thin metal foil and provided with a frame plate (7) for a die (16), a guide plate (10) for a punch (11), and a guide arranging for the die (16) and the punch to cooperate in the desired manner for the purpose of processing a thin metal foil by the die and the punch. The guide consists of at least two hinge elements (8, 9), each connected by means of an elastic line hinge (4, 5) with both the frame plate and the guide plate, the line hinges allowing only a pivotal motion in substantially the rectilinear displacement. The frame plate, the guide plate and the guide are manufactured from a single block (1) of material, in which the frame plate, guide and guide plate connected by the elastic line hinges are formed by the provision of bores (3), slits (6) and/or recesses (2).

摘要： A method and apparatus for deep drawing a product from a blank (5), in which, during deep drawing, the blank (5) is held near its edge by a downholder (8) against a die ring cooperating with the downholder (8), thereby preventing, at least reducing wrinkle formation in the blank, by adjusting, at the beginning of deep drawing, the downholder (8) such that a downholder (8) force exerted by the downholder (8) on the edge of the blank is relatively small, and by controlling, during the further course of the process, the downholder (8) on the basis of a predetermined thickness trend of the mentioned edge during deep drawing and/or a trend or critical value derived from this thickness trend.
