Abstract: A clamping device for internal high-pressure forming includes a tool carrier (1), a tension clamping holder (3, 4) which extends from the tool carrier (1), a clamping jaw (8) which is arranged opposite from the tool carrier, and a bayonet clamping device (13-16) for holding together the forming tool parts between the clamping jaw and the tool carrier, which bayonet clamping device (13-16) wedges the clamping jaw between the tension clamping holder and the forming tool. The tension clamping holder has at least one feed opening which is suitable for guiding the forming tool into the working position in a direction vertical to the clamping direction. This solution substantially facilitates the installation of forming tools in the device.

Abstract: The invention is directed to a forming device, especially internal high-pressure forming device, with a multiple-part forming tool and a clamping device which holds the parts of the forming tool together against the deforming action. In the novel forming device, according to the invention, the clamping device and/or the forming tool have/has at least one counter-clamping device which compensates at least partially for deformations of the mold cavity during forming. The possibility of compensation according to the invention makes it possible to construct the clamping and/or forming tool parts in a less solid manner.
