Quenching and shaping device for forming of U-shaped bottom deck

The invention provides a U-shaped bottom deck forming, quenching and shaping device which comprises an upper die body assembly, an upper water spraying assembly, a lower die body assembly, a lower water spraying assembly, a guide sleeve and a guide column. The upper water spraying assembly is fixed to the upper die supporting plate through a hoop, the lower water spraying assembly is fixed to the lower die lower rib plate through welding, and the relative position of the upper die body assembly and the relative position of the lower die body assembly are determined through a guide sleeve and a guide column. According to the device, a profiling and quenching method is applied to the bottom deck, a hot pressing forming process and a quenching process are combined into one, and the characteristic that an ultrahigh-strength special steel material is easy to form at an austenitizing temperature and the advantage that the ultrahigh-strength special steel material is subjected to quenching, cooling and forming under
