Abstract

Eine Vorrichtung zum hydraulischen Tiefziehen eines Metallbleches (20) besitzt ein 1. Werkzeug (11), das eine Formkontur aufweist, und ein 2. Werkzeug (12) in Form eines einen inneren Fluidraum (21) bildenden Wasserkastens mit einer Bodenplatte (14) und einer umlaufenden, in lösbarer Weise dicht auf der Bodenplatte (14) angebrachten Seitenwand (13). Das umzuformende Blech (20) kann in einer den inneren Fluidraum (21) überspannenden Weise auf die Seitenwand (13) aufgelegt und mittels eines Blechhalters (16) fluiddicht gegen die Seitenwand (13) gespannt werden. Um in einfacher Weise eine Anpassung des 2. Werkzeug (12) an verschiedene Bauteilformen zu ermöglichen, umfaßt die Seitenwand (13) zumindest ein auf der Bodenplatte (14) aufgelagertes Stützteil (15) und einen Druckring (19), der auf der dem 1. Werkzeug (11) abgewandten Außenseite des Stützteils (15) in Abstand zu diesem angeordnet ist, wobei auf das Stützteil (15) und den Druckring (19) eine von einer Spannvorrichtung (18) beaufschlagte Konturplatte (17) dichtend aufgelagert ist, über die das Stützteil (15) und das Dichtungsteil (19) gegen die Bodenplatte (14) gespannt sind.

Figure 00000001
A device for the hydraulic deep drawing of a metal sheet (20) has a 1st tool (11) which has a contour, and a 2nd tool (12) in the form of a water box forming an inner fluid space (21) with a base plate (14) and a peripheral side wall (13) which is detachably attached tightly to the base plate (14). The sheet metal (20) to be formed can be placed on the side wall (13) in a manner that spans the inner fluid space (21) and can be clamped against the side wall (13) in a fluid-tight manner by means of a sheet metal holder (16). In order to allow the second tool (12) to be adapted to different component shapes in a simple manner, the side wall (13) comprises at least one support part (15) supported on the base plate (14) and a pressure ring (19) on the first The tool (11) facing away from the outside of the support part (15) is arranged at a distance from the latter, a contour plate (17) acted upon by a clamping device (18) being sealingly supported on the support part (15) and the pressure ring (19), via which the support part (15) and the sealing part (19) are clamped against the base plate (14).
