The invention discloses a bending forming process method, a pipe and a vehicle. The bending forming process method comprises the steps that a process groove is cut in a pipe so as to enable the pipe to be divided into a first pipe part and a second pipe part by the process groove; and bending moment is applied to the first pipe part and/or the second pipe part to enable the process groove to be folded. According to the bending forming process method, the pipe can be bent and formed through the small bending moment in a cold machining mode, and can be formed into a complex bending shape, and therefore the pipe bending forming difficulty and machining cost are reduced favorably.

    本发明公开了一种折弯成型工艺方法及管材和车辆。该折弯成型工艺方法包括:在管材上切割工艺槽,以使所述管材被所述工艺槽分成第一管部和第二管部;对所述第一管部和/或所述第二管部施加折弯力矩,使所述工艺槽合拢。根据本发明的折弯成型工艺方法,可以冷加工的方式,通过较小的折弯力矩将管材折弯成型,且可以成型为复杂的折弯形状,从而有利于降低管材折弯成型的难度和加工成本。
