The invention provides a novel tube bending machine, and relates to the field of tube bending machines. The novel tube bending machine comprises a working table, wherein a machine groove is formed inthe surface of the working table, a hydraulic machine is fixedly connected to the inner wall of the machine groove, a bent tube tapping die is hinged to the output end of the hydraulic machine, an arc-shaped bent tube swing groove is formed in the lower surface of the bent tube tapping die, a bent tube extrusion plate is arranged on the inner wall of the arc-shaped bent tube swing groove, a plurality of first clamping grooves are formed in the surface of the bent tube extrusion plate, a plurality of second clamping grooves are formed in the inner wall of the arc-shaped bent tube swing groove,and first connecting balls are rotationally connected to the inner walls of the first clamping grooves. Compared with traditional damping, the novel tube bending machine has the advantages that swingcaused by the tube bending machine is utilized, the tube bending machine is made to swing regularly, the contact surface is increased, and the cutting force is reduced, so that the problems that due to the fact that a common pipeline bending machine is prone to generate small-amplitude swing when the bending torque is large, the contact surface between a pipeline and a mold is prone to cut each other and to be damaged in the swinging process, and then waste of resources is caused, and meanwhile, the working progress can be influenced are effectively solved.

The invention discloses a library and information classification system unit, aiming at solving a problem that books, which are relatively complex in classification, can be easily mixed by operating personnel well and aiming at improving working efficiency and avoiding faults in work. According to the technical scheme, the system unit comprises a base plate, wherein partition boards are arranged on the base plate; a storage cabinet, which is rotatable, is arranged between every two partition boards; a cover plate, which can slide back and forth along the upper end face of the corresponding partition board, is arranged at the upper side of each storage cabinet; supporting plates, which are arranged at the back sides of the partition boards, are arranged on the upper end face of the base plate; movable plates are arranged on the supporting plates; through holes, which correspond to cover plates, are formed in the movable plates; guide pillars, which are arranged in a mode of being eccentric with the through holes, are each arranged on the rear end faces of the cover plates; a semicircular clamping block is arranged at one side, deviating away from the circle center of the corresponding through hole, of each guide pillar; the end face of the rear side of each clamping block is an inclined plane; the movable plates can be squeezed to move leftwards and rightwards when the cover plates are moved backwards; a first spring is connected between each cover plate and the corresponding supporting plate; and when each cover plate is moved backwards, other cover plates, under the actions of the first springs, can get reset. The system unit provided by the invention is skillful in structure and novel in concept.
