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.
La présente invention se rapporte à un dispositif et un procédé pour tenir ensemble des parties d~un outil (2a, b) lors d~un processus d~hydroformage. Le dispositif comprend une première partie (1), incluant une première surface de transmission de force (1b) et une seconde partie (4) comprenant une seconde surface de transmission de force (4c), qui sont reliées au moyen d~un pivot (5), et un membre de puissance de longueur variable qui, avec une force (F1), tente de retourner la seconde partie (4) en fonction de la première partie (1) autour du pivot (5), via un premier levier (l1), qui est plus long qu~un second levier (l2), au moyen duquel une plus grande force résultante (F2) est créée. Cette seconde force agit entre lesdites surfaces de transmission de force (1b, 4c) pour tenir ensemble les parties de l~outil (2a, b) pendant un processus d~hydroformage.
