The invention discloses a spray type composite hot stamping forming device, which comprises a servo motor, a transmission component, a working component, a cooling component, a guide pole and a frame, wherein a power component, the transmission component, the working component, the cooling component and the guide pole are arranged on the frame. According to a spray type composite hot stamping forming and quenching process disclosed by the invention, the process comprises the following steps: at first, a mould is arranged on a slider block and a lower pressure plate, the position of the slider block is adjusted through a limiting switch, and the position of a spray head is adjusted, so that the effluent position of cooling liquid aligns at the position of a plate material so as to reach the expectant cooling effect conveniently. According to the invention, when the device is used, high-intensity steel is placed in the mould of a transverse stamping forming machine, so that hot stamping forming is completed quickly, and through a manner of spraying the cooling liquid instantly, the formed high-intensity steel can simultaneously realize pressure maintaining and quenching.
