Example Embodiment
[0039] This embodiment is an electro-hydraulic forming device that realizes tube forming through bulging.
[0040] This embodiment includes a bulging mold, a power supply 6, a water pipe 10, a water storage tank 8, a water medium 9, a metal wire 14, a positive electrode and a negative electrode.
[0041] In this embodiment, the upper mold 7 and the lower mold 12 are combined to form a bulging mold of the pipe, and the pipe 13 to be formed is placed in the cavity of the bulging mold. The positive electrode is installed at one end of the tube to be formed, and the negative electrode is installed at the other end of the tube to be formed. The positive electrode is connected to the positive electrode of the power source 6 through a wire 5, and the negative electrode is connected to the negative electrode of the power source 6 through a wire 5. The metal wire 14 is located in the center of the tube 13 to be formed and coincides with the axis of the tube 13 to be formed; the two ends of...
