Hot rolled steel coil taping device

Abstract

The invention relates to a hot rolled steel coil taping (bundling) device, which comprises a driving device, a bundling box trolley in transmission connection with the driving device, a hydraulic device, a bundling press device for bundling steel coils, a taping machine and an axial locking clamp. By using the hot rolled steel coil taping (bundling) device, tail bounced-off parts of the steel coils are compressed hydraulically; after bounced-off gaps on tail parts are reduced, outer circles of the steel coils are bundled with 4 to 6 bundling belts and a pair of clamps for locking the steel coils axially, and the tail bounced-off parts of the steel coils are frapped; and simultaneously, the packaging and bundling continuity is realized, and a steel coil shaft is bundled radially. The hot rolled steel coil taping (bundling) device fundamentally eliminates the original complicated operating mode, and fundamentally solves the problems of strip breakage and bounce of steel strips and unwinding of the steel coils in the process of stacking and transporting the steel coils after bundling.

Description

technical field [0001] The invention relates to a binding device, in particular, the invention relates to a binding (binding) device for hot-rolled steel coils of metallurgical pipeline steel. Background technique [0002] In the field of metallurgy, the X series pipeline steel rolled by the hot rolling production line is mainly directly supplied to deep processing users. For this reason, in order to facilitate the transportation of the hot-rolled steel coils, the steel coils must be bundled before leaving the factory. The purpose of the bundled processing is to avoid loosening of the steel coils during long-distance transportation. [0003] The steel coil bundling equipment in the finishing workshop of the hot rolling mill belongs to the applicable equipment for ordinary hot rolling plates. When it performs bundling operations on hot-rolled high-strength steel such as X80 pipeline steel, hot-rolled steel coils such as X80 pipeline steel have high strength and high elastici...

AI Technical Summary

Problems solved by technology

However, at the tail of the steel coil, due to the abnormal shape of the tail steel plate, its original shape cannot be pressed and tightened by the strap tightener of the strapping machine during the tightening operation of the strapping strap. Therefore, this high-strength steel It is unavoidable for coils to use the existing bundling method to avoid the phenomenon of tail warping, and the tail can only be stacked, transferred, and hoisted under the state of warping and bouncing, and the steel coils in the state of warping and bouncing The problems that exist during stacking and transshipment are:

[0007]2) When the bundled steel coils are stacked in the steel coil warehouse, because the tail of the steel coils cannot be directly pressed against the outer layer of the steel coils, the gap between the two steel coils It is easy to cause the steel strip to be broken or hang up when one of the steel coils is hoisted, as shown in the figure below

[0008]3) Since the tail of the steel coil cannot be effectively pressed against the outer surface of the steel coil when it is bundled, it is easy to cause the management personnel of the steel coil warehouse to be broken in the warehouse area The damage caused by the rebound of the rear plate

[0009]4) The tail of the steel coil in the state of warping and springing cannot be effectively handled, resulting in insecure binding, and the binding belt was pulled off before leaving the factory, scrape off

Although it can be repaired, it also causes a waste of strapping. Once the steel coil breaks on the way, the consequence is that the loose coil will hurt people, and the uncoiled coil is very troublesome to deal with.

[0010]5) The steel coil is re-opened in the hands of the user. The spring-off part of the tail of the steel coil is not easy to roll on the ground roller. If it is reversed, it will only cause the steel coil to deviate , the deviation caused the entire coil to be scrapped

[0011]In addition, due to the existing steel coil packaging and bundling includes: manual cutting of the strap, a single strap wearing a lock, preparation of bundling tools, steel coil circumferential Threading and tightening the strapping and aligning the buckle bayonet operation, radial threading of the steel coil and gasket operation, repairing operation of the broken coil, directing the driving vehicle to lift the broken coil to the bundling area and repairing In addition to the above-mentioned problems, the operation of breaking strips and steel coils is complicated, time-consuming and labor-intensive
