  • Patent number: 11975376
    Abstract: The embodiment of the present disclosure provides fluid bulging equipment for thin plate parts, which includes a main mechanism, a left mold opening mechanism and a right mold opening mechanism located on both sides of the main mechanism, a left mobile working platform, and a right mobile working platform. The main mechanism includes a main frame and a main oil cylinder located under the main frame. The main oil cylinder is connected to a master cylinder mold-locked booster cylinder through an oil circuit block. A hydraulic control system is arranged above the main mechanism. An ultra-high pressure generating device is arranged in the hydraulic control system. The ultra-high pressure generating device is connected to the master cylinder mold-locked booster cylinder through a pipeline. The hydraulic control system is also connected to the left mold opening mechanism and the right mold opening mechanism.
