Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled plate and strip production equipment, in particular to an end sheath of a cold-rolled plate and strip steel coil. Background Art

[0002] Currently, cold-rolled steel coils are a crucial raw material in domestic steel processing and transportation. The integrity of their protection is directly linked to maintaining product quality and ensuring smooth processing. Effective protection is particularly crucial for coil edges, as they are relatively fragile and susceptible to damage during handling, storage, and transportation.

[0003] Currently, the industry generally uses fiberglass reinforced plastic (FRP) guard plates to protect the edges of cold-rolled steel coils. FRP, a composite material combining glass fiber reinforcement with a resin matrix, boasts lightweight, high strength, and corrosion resistance, and was initially considered an ideal protective material. However, with increasing practical application, its limitations have become increasingly apparent.

[0004] Specifically, fiberglass panels are subject to the immense pressure of lifting, especially when operated with unprofessional or outdated lifting equipment. They often struggle to withstand the sudden impact, leading to cracks, breaks, and other damage. Furthermore, improper lifting equipment operation or collisions can accelerate the damage. These damages not only eliminate the effective protection of the steel coil edges but also pose a threat to the surrounding environment and personnel safety through falling fragments.

[0005] More seriously, once the protective plate is damaged, the edge of the cold-rolled steel coil is directly exposed, increasing the risk of damage during subsequent handling and stacking. This not only affects the appearance of the steel coil but also may damage its internal structure, leading to increased processing difficulty and reduced yield, which in turn negatively impacts the efficiency and cost of the entire production chain. A cold-rolled steel coil end protective cover is now provided to address this technical problem. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-2In the embodiments of this utility model, an innovative cold-rolled steel coil end guard is described in detail. This guard is designed to significantly enhance the safety and protection of the steel coil during transportation, storage, and processing. The cold-rolled steel coil end guard primarily comprises an inner sleeve 1, an outer sleeve 2, and a bumper ring 3. The outer sleeve 2 is positioned at one end of the inner sleeve 1, and the bumper ring 3 is positioned at the outer edge of the outer sleeve 2. The bumper ring 3 and the inner sleeve 1 are positioned on either side of the outer sleeve 2. These three elements work together to provide comprehensive protection for the edges of the cold-rolled steel coil.

[0023] Specifically, the inner sleeve 1, the core of the sheath, is designed to fit snugly around the coil core, ensuring a secure installation. The outer sleeve 2, located at one end of the inner sleeve 1, not only enhances the overall structural strength of the sheath but also, through its wide range of dimensions, effectively wraps around the coil edge. The anti-collision ring 3, a key protective element of the sheath, is positioned at the outer edge of the outer sleeve 2. Its unique design effectively absorbs and disperses external impacts, such as from collisions with the spreader, thereby protecting the coil edge from damage during handling.

[0024] Notably, the design of this new protective sheath takes full account of versatility and adaptability. It can accommodate steel coils with a coil diameter of 508mm or 610mm, meeting the protection requirements of steel coils of varying specifications. Furthermore, the sheath is manufactured using an integrated injection molding process, ensuring a tight connection between all components and overall structural stability. PE (polyethylene) was selected as the material, which is not only odorless and non-toxic, offering excellent environmental performance, but also has a waxy feel and is easy to process and shape. More importantly, PE offers excellent impact resistance, abrasion resistance, and chemical corrosion resistance, ensuring long-term, stable protection in harsh industrial environments.

[0025] In terms of detailed dimensions, the inner sleeve 1 in this embodiment is designed as a circular ring structure with an inner diameter of 508mm, a length and thickness of 10mm, and an inner sleeve margin of 100mm. The outer sleeve 2 has an enlarged outer diameter of 685mm to fully cover and protect the edge area of ​​the steel coil. The anti-collision ring 3 is set to be 20mm thick and 15mm high. This design ensures sufficient anti-collision and cushioning capabilities while avoiding unnecessary material waste.

[0026] When in use, the utility model is installed at the coil core of the steel coil. The utility model can adapt to the steel coil with a coil diameter of 508 or 610 mm. At the same time, the anti-collision buffer ring can eliminate the damage to the edge caused by the collision of the sling during the lifting and circulation link.
