A rotary cutting anti-creeping energy absorption device comprises an anti-creeping tooth cross beam, anti-creeping teeth are installed on the outer side face of the anti-creeping tooth cross beam, and a front bearing for supporting a screw to rotate is installed in the center of the inner side face of the anti-creeping tooth cross beam. A spiral sleeve is mounted at the position of a center hole in the inner side of the mounting plate, and spiral teeth matched with the external threads on the screw rod are arranged in the spiral sleeve; the outer side of the mounting plate is provided with a spiral cutter for cutting off external threads of the screw and a screw axial cutter for axially cutting the screw; the two ends of the thin-walled tube are fixedly connected to the anti-creeping tooth cross beam and the mounting plate; the cutting base body is arranged in the thin-walled tube, one end of the cutting base body is fixed to the mounting plate, the other end of the cutting base body is open, and the screw and the spiral sleeve are both located in the cutting base body; and the rotating disc is fixedly connected to the end, close to the anti-creeping tooth cross beam, of the screw rod, and the rotating disc is provided with an axial cutting knife used for cutting the end face of the open end of the cutting base body and a circumferential cutting knife used for cutting the side wall of the cutting base body. The energy absorption efficiency can be greatly improved, and the anti-climbing effect is achieved.

    一种周旋式切削防爬吸能装置,包括防爬齿横梁,其外侧面安装防爬齿,内侧面的中心位置安装有支撑螺杆转动的前轴承;安装板,其内侧的中心孔位置安装有螺旋套筒,螺旋套筒内设有与螺杆上外螺纹配合的螺旋齿;安装板外侧设有用于切除螺杆外螺纹的螺旋切削刀以及对螺杆轴向切削的螺杆轴向切削刀;薄壁管,其两端固接在防爬齿横梁和安装板上;切削基体,设置在薄壁管内,切削基体的一端固定在安装板上,另一端敞口,螺杆和螺旋套筒均位于切削基体内;转盘,固定连接在螺杆上靠近防爬齿横梁的一端,转盘上设置用于对切削基体敞口端端面切削的轴向切削刀以及用于对切削基体侧壁切削的周向切削刀。本发明可以极大地提高吸能效能,起到防爬的作用。
