The invention provides a straight profile wide-angle bending structure, a machining method and an energy-absorbing anti-collision beam, and belongs to the technical field of automobile parts, the straight profile wide-angle bending structure comprises a profile body which is of a hollow structure, the profile body is provided with a to-be-bent part, the to-be-bent part sinks towards the interior of the to-be-bent part so as to form at least two induction parts, and the to-be-bent part is provided with a through hole; the induction parts are distributed in the length direction of the sectional material body, and when the sectional material body is bent, the induction parts deform. The sectional material has the beneficial effects that the sectional material body is guided to be bent in the mode that the induction part is arranged on the sectional material body, and when the sectional material body is bent, the induction part deforms, so that the bending difficulty is greatly reduced; the problem that in the prior art, due to the fact that the fluidity of a profile material is poor and the ductility of an extruded profile is low, large-angle bending cannot be conducted is solved.

    本发明提供了一种直型材大角度弯曲结构、加工方法以及吸能防撞梁,属于汽车零部件技术领域,包括:型材本体,其为空心结构,所述型材本体设置有待弯曲部,所述待弯曲部朝自身的内部凹陷从而形成诱导部,所述诱导部的数量为至少两个,所述诱导部沿所述型材本体的长度方向分布,当所述型材本体被弯曲时所述诱导部形变。本发明的有益效果为:采取在型材本体设置诱导部的方式来引导型材本体弯曲,当型材本体被弯曲时诱导部形变,从而大大降低弯曲难度,克服了现有技术中型材材料的流动性差以及挤出型材的延展性低从而导致无法进行大角度的弯曲的问题。
