ABSTRACT:
A method is provided for forming an elongated multi-lateral member from a round tube. A die is provided having a first die member and a second die member movable relative to the first die member between open and closed positions. The first and second die members define a first pair of opposed surfaces which each lie in a plane angled slightly with respect to an axis of movement of the second die member. The first and second die members further define a second pair of opposed surfaces which lie in a plane generally perpendicular to the first pair of opposed surfaces and which combine with the first pair of opposed surfaces to define a die cavity. The first pair of opposed surfaces are angled slightly relative to an axis of movement of the second die member in order to allow separation of the first and second die members while providing a small projected surface in the direction perpendicular to the axis of movement of the second die member such that the amount of force necessary to hold the second die member in a closed position during the step of expanding the tube by hydroforming is kept to a minimum.
