One-time die pressing device for U-shaped plate of special-shaped seat beam

The utility model relates to the technical field of seat beam U-shaped plate pressing dies, in particular to a one-time pressing die device for a special-shaped seat beam U-shaped plate. According to the technical scheme, the device comprises a pressing mechanism and a forming mechanism, the pressing mechanism comprises an upper die base, a connecting plate is arranged above the upper die base, the forming mechanism comprises a lower die base, a push plate is arranged between two sets of forming limiting plates and located above the lower die base, and an adjusting mechanism is installed on one side of one set of forming limiting plates. The pressing mechanism and the forming mechanism are arranged in an up-down separated mode, one-time forming of the seat beam U-shaped plate can be achieved, workshop production efficiency is improved, meanwhile, butt welding seams of assembly of the seat beam U-shaped plate are reduced, the risk of cracking of the seat beam U-shaped plate caused by assembly and welding seam
