AI Technical Summary

Technical Problem

In existing hot rolling production line coil winding devices, the coil and the limiting plate are fixed structures, which makes it difficult to disassemble the steel coil after quantitative winding, affecting transportation efficiency.

Method used

A coil winding device is designed, comprising a base, a movable seat, an inner liner shaft, a drive motor, and a telescopic connector. The inner liner shaft is detachably connected to the I-beam reel. The automatic release of the steel coil is achieved through the drive motor and the telescopic assembly. The device is combined with a buffer seat and a shock absorber for buffering and shock absorption.

Benefits of technology

It enables convenient disassembly and transportation of steel coils, improving production efficiency, and reduces the impact force when the steel coils fall through the buffer seat and shock absorber, ensuring safety.

Abstract

The utility model discloses a coiled material winding device for a hot rolling production line, and relates to the technical field of hot rolling production. The device comprises a base, a workbench, movable seats and a telescopic connecting piece, receding grooves allowing the two movable seats to horizontally move are symmetrically formed in one side of the upper end of the base, mounting seats are fixed to the tops of the two movable seats, and lining shafts used for abutting against spools are rotationally connected into the two mounting seats through bearings. The two lining shafts can be used for fixing, driving and rotating the I-shaped wheel for winding the steel coil, and the limiting nut can be unscrewed in the later period so that the sleeve and the extension shaft can be stretched. The driving motor is started to enable the threaded sleeve outside the double-end lead screw to drive the two movable seats to do synchronous far-reaching motion, and in the process, the two lining shafts abutting against the interior of the spool are separated from the spool, and then the steel coil falls to the arc-shaped supporting block to be taken out by a worker.
