Straight profile large-angle bending structure, machining method and energy-absorbing anti-collision beam

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 pr
