<p>The present invention relates to a device and a method for holding tool parts (2a, b) together during a hydroforming process. The device comprises a first portion (1 ) comprising a first force transmitting surface (1 b) and a second portion (4) comprising a second force transmitting surface (4c), which are connected by means of a pivot (5), and a length variable power member which, with a force (F1), tends to turn the second portion (4) in relation to the first portion (1 ) around the pivot (5) by means of a first lever (I1) which is longer than a second lever (I2) by means of which a resultant larger force (F2) is created which acts between said force transmitting surfaces (1 b, 4c) for holding the tool parts together (2a, b) during a hydroforming process.</p> |
