Abstract
Die Erfindung bezieht sich auf ein Ziehwerkzeug 1 zur Umformung von Werkstücken 2 in einer Presse, insbesondere zur Umformung von Blechen zu einem Formteil mit einem Ziehstempel 5 und einem dem Werkstück 2 zugeordneten Werkstückträger 3, wobei der Werkstückträger 3 an einem Werkzeugteil 4 abstützbar und zur Umformung des Werkstückes relativ zu diesem bewegbar ist und mit einer Matritze. Um pressenseitige Einflüsse zu verringern, ist vorgesehen, dass an dem Werkstückträger 3 ein kraftadaptierter Werkstückhalter 8 vorgesehen ist, der über Kraftadapter relativ zu dem Werkstückträger 3 beweglich ausgebildet ist (Fig. 1). The invention relates to a drawing tool 1 for forming workpieces 2 in a press, in particular for forming sheets into a molded part with a punch 5 and the workpiece 2 associated workpiece carrier 3, wherein the workpiece carrier 3 can be supported on a tool part 4 and for forming of the workpiece is movable relative to this and with a die. To reduce press-side influences, it is provided that a force-adapted workpiece holder 8 is provided on the workpiece carrier 3, which is designed to be movable relative to the workpiece carrier 3 via force adapters (FIG. 1).
