Continuous transfer winding and unwinding equipment and method

Abstract

The invention discloses continuous transfer winding and unwinding equipment and method, and relates to the technical field of winding equipment. The winding and unwinding equipment comprises a rolling mill, a shearing and punching device, a first station mechanism, a movable machine base, a head making machine, a second station mechanism and a drawing machine which are sequentially arranged, the first station mechanism comprises a first winding machine and a first pinch bending machine, and the second station mechanism comprises a second winding machine and a second pinch bending machine. The two winding machines are arranged to continuously and alternately wind and unwind the pipe blank rolled by the rolling mill and the pipe blank before being drawn by the drawing machine without waiting for material circulation between the rolling procedure and the drawing procedure, buffering of pipe blank winding and unwinding between the rolling mill and the drawing machine is achieved, the phenomenon that the rolling mill stops and waits for machining of the drawing machine is avoided, and the production efficiency is improved. And meanwhile, the cut tail end can be subjected to head manufacturing treatment through the head manufacturing machine which is adjusted in a moving and rotating mode, and a drawing machine can conduct drawing conveniently.

Description

technical field [0001] The invention relates to the technical field of rewinding equipment, in particular to a continuous transfer rewinding and unwinding equipment and method. Background technique [0002] Planetary rolling and linear drawing are two important production processes on the tube billet continuous casting and rolling production line, both of which reduce the diameter of the tube billet and reduce the metal deformation of the wall. Planetary rolling and drawing are two production processes that are connected before and after, but their production processes and production speeds are different. Therefore, generally, the rolled tube blank is wound first, and then drawn and unwinded after the winding is completed. The turnaround from the rewinding station to the unwinding station requires turnaround time. During the turnaround process of the rewinding machine, the rolling and drawing production processes are interrupted, thus affecting the continuous production of r...
