| 摘要 |
The invention concerns a clamping device for a device for the production of metal parts by forming with a closed forming tool, the clamping device comprising at least several tension hoops ( 2 ), these tension hoops ( 2 ) each being provided with at least one tension frame ( 2.2 ) of a closed contour, the tension frame being provided with two segments ( 2.3 ) arranged opposite each other at some distance, between which a forming tool ( 12 ) can be arranged, each of these segments ( 2.3 ) being provided with at least either one bearing surface ( 2.1 ) or one bearing surface ( 2.4 ), and the tension hoops ( 2 ) being each linked by at least one articulated joint ( 8 ) in order to be pivoted, a bearing surface ( 3.1 ) which is located above or on the upper surface of the forming tool ( 12 ) and used as support for a bearing surface ( 2.1 ) of a tension hoop ( 2 ), and a device ( 5 ) which generates a clamping force of more than 3 MN and is composed of several power-generating elements.
