Abstract
A warm hydro-forming device comprises: an upper mold and a lower mold respectively mounted to an upper mold die and a lower mold die; a lifting die installed to the lower mold die through a guide unit, an upper portion of the lifting die being connected to the upper mold die through a lifting unit to cooperatively operate in an upward and downward direction with the upper mold die; a pair of hydraulic pressure cylinders for providing an axial compression force to the tube component and supplying a forming hydraulic fluid into the tube component; an ascending and descending unit for ascending or descending the upper mold die; and a heating unit associated with the lifting die such that the heating unit can move toward or away from the tube component. The heating unit heats the tube component and a forming hydraulic fluid through a high frequency induction heating.
