Abstract: The invention provides a hydroforming apparatus for forming a length of tube. A hydroforming press includes an upper platen and a lower plate. A first die set is provided for forming a first lengthwise portion of the tube and a second die set provided adjacent the first die set which forms a second lengthwise portion of the tube. A first pivot acts between a first and second upper die so that the second upper die can be pivotally adjusted on the upper platen relative to the first upper die. A second pivot acts between a first and second lower die so that the second lower die can be pivotally adjusted on the lower platen relative to the first lower die. A die insert is provided having an upper die insert and a lower die insert that define upper and lower insert cavities that connect together the first and second cavity portions of the upper die set and the lower die set. This die insert is removably mounted as needed to accommodate the pivotal adjustment between the first and second die sets.
