Radial fastening device of high-strength hot rolled strip steel coil

Abstract

The invention relates to the field of hot rolled strip steel packaging, in particular to a radial fastening device of a high-strength hot rolled strip steel coil. The radial fastening device comprises a radial fastening strip. The radial fastening strip comprises a large horizontal plate, middle connection plates, small horizontal plates and bolt holes. The large horizontal plate, the middle connection plates and the small horizontal plates are formed by cold-bending hot rolled strip steel. The middle connection plates and the small horizontal plates are each symmetrically arranged on the two sides of the large horizontal plate in a bent mode. The multiple bolt holes are formed in the small horizontal plates. Through the design of the radial fastening strip, an auxiliary storage table and an automatic transport mechanism, the degree of automation is increased, efficiency is improved, excessive manual participation is avoided, labor is saved, and the problem of casualties in the operation process is avoided.

[0002] After the hot-rolled strip is rolled by a rolling mill and coiled by a coiler, it is unloaded from the coiler by an unloading trolley and transported to the bundling stand, where it is bundled by the strapper. The width and thickness of the steel coils are determined by the width and thickness of the steel coils; during online production, the high-strength hot-rolled strip steel coils are re-bundled with steel coil strapping belts, resulting in slow transportation of steel coils in the hot-rolling production line by walking beam chains, which seriously restricts such The production capacity of strip steel production is limited, and at the same time, the frequency of manual replacement of strapping straps is increased, resulting in the consumption of a large amount of strapping straps

However, for low-temperature high-strength dual-phase steel, steel for automobile beams, steel for pipelines and other types of steel, the yield strength of the strip steel is high, and the steel coil cannot be effectively bound by the steel coil strapping alone, which can easily cause high-strength hot-rolled strip steel. During the process of hoisting, loading, unloading, etc., the straps break and fall off, and the steel coils are uncoiled and uncoiled. Big security risk
