<p>The invention relates to a manufacturing method for curved and quenched profile elements from closed profile elements, beams, or similar by using a die tool (5) for curving the profile elements, a profile element (2) heated to the quenching temperature being pushed into the die tool and curved to a form provided by the die tool, whereafter the profile element is cooled down by means of a flushing or a showering with a cooling liquid, the cooling liquid being supplied to the die tool (5) with the therein contained and curved porfile element (2) and in that the cooling liquid is led through the die tool (5) and thereby on the outside of the therein contained profile element. For performing the invention a die tool is used of a type comprising several tool halves (9, 9') adapted to cooperate to curve a profile element placed in the die tool (5) and between the tool halves in pushing said tool halves together, each of the tool halves (9, 9') on its inside then being provided with facing, alternating, circumferential ribs (13) and grooves (14) running continously along said insides for transporting a cooling liquid through the die tool and thus dissipating heat from the outside of the die in the tool (5) contained profile element (2).</p> |
