Description

Technical Field

[0001] This utility model relates to the technical field of steel coil packaging auxiliary equipment, specifically to an auxiliary tool for installing corner protectors on cold-rolled coil cores. Background Technology

[0002] In the steel strip production process, after rolling, coiling, and finishing, the finished steel strip needs to be packaged into coils before packaging. Packaging is the final step in this process and is crucial for protecting the product and facilitating storage and transportation. Because steel coils are susceptible to various external factors during storage and transportation, such as impact, moisture, pressure, rust, humidity, and dust, these factors can damage the quality of the steel coils. Therefore, appropriate packaging materials and techniques are needed, such as rust-resistant corrugated paper, which can effectively protect the steel coils from these adverse factors and ensure they arrive at their destination in good condition.

[0003] The packaging process for cold-rolled coil includes fixing inner and outer paper corner protectors, wrapping with outer anti-rust paper, laying core paper, folding paper, putting on plastic bags, laying outer sheet metal, transferring the coil, assisting with outer sheet metal packaging, tidying up plastic bags, placing inner sheet metal, placing inner and outer corner protectors, end guards, circumferential binding, eyelet binding, labeling, and warehousing. The corner protector installation process at the core is the most challenging. Because only the outer circumference of the cold-rolled coil is packaged and secured to prevent unraveling during transport when it leaves the production line, the inner parts are not restrained. During transport, the inner hole of the coil serves as a lifting hole; the pressure from the lifting equipment on the inner ring can easily cause deformation or inward unraveling of the steel plate at the inner hole. This results in the inner ring of the steel plate not reaching the original design dimensions during subsequent packaging, ultimately making the installation of the outer corner protectors at the core difficult or even impossible.

[0004] Therefore, in order to solve the above problems, this utility model provides an auxiliary tool for installing corner protectors of cold-rolled coils. It is not only simple in structure and easy to operate, but also helps workers to quickly complete the packaging of steel coils, thereby improving work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tool for installing corner protectors on cold-rolled coil cores, so as to solve the problem of difficulty in installing corner protectors when packaging steel coils after they have unraveled inwards.

[0006] To achieve the above objectives, the basic solution provided by this utility model is as follows: an auxiliary tool for installing corner protectors of cold-rolled coils, including a main shaft, a first flange fixedly connected to one end of the main shaft, a second flange fixedly connected to the main shaft, a third flange movably sleeved on the other end of the main shaft, a lead screw provided at one end of the main shaft connected to the third flange, a sleeve threadedly connected to the lead screw, a first support rod hinged to the first flange and the second flange, an arc-shaped support plate hinged to the other end of the first support plate, a second support rod hinged to the third flange, and the other end of the second support rod hinged to the arc-shaped support plate.

[0007] The working principle of this utility model is as follows: When in use, the operator first rotates the sleeve clockwise, causing the sleeve to push the third flange to slide on the main shaft. At the same time, the second support rod drives the arc-shaped support plate to expand outward, so that the arc-shaped support plate contacts the inner ring of the steel coil, thereby expanding the inner ring of the steel coil. Then, the installation of the steel coil core corner protector can be carried out.

[0008] The beneficial effects of this utility model are as follows: This utility model achieves the expansion of the arc-shaped support plate outward and its support on the inner ring of the steel coil by moving the sleeve on the lead screw to abut against the third flange and making the third flange slide on the main shaft. This design provides convenience for the installation of cold-rolled coil corner protectors. It is not only simple in structure and easy to operate, but also can quickly help workers complete the installation of cold-rolled coil corner protectors, thereby improving work efficiency.

[0009] Option 2, which is a preferred option of the basic option, is provided with a rubber isolation ring on the end of the sleeve that contacts the third flange; this can prevent the sleeve and the third flange from directly contacting each other, thereby reducing the wear of the sleeve on the third flange.

[0010] Option 3, a preferred option of the basic option, is provided with a return spring on the main shaft, which is located between the second flange and the third flange, and the other end of the return spring is fixedly connected to the first support rod; the elasticity of the return spring can help the arc-shaped support plate to quickly return to its original position.

[0011] Option 4, which is a preferred option of the basic option, is provided with a rubber pad on the arc-shaped support plate; this can prevent the arc-shaped support plate from directly contacting the steel coil and causing wear to the steel coil.

[0012] Option 5, which is a preferred option of the basic option, has a handle fixedly connected to the sleeve; this facilitates control of the sleeve's movement on the lead screw. Attached Figure Description

[0016] The present invention will be further described in detail below through specific embodiments:

[0017] The reference numerals in the accompanying drawings of the instruction manual include: 1. spindle; 2. first flange; 3. second flange; 4. third flange; 5. lead screw; 6. sleeve; 7. first support rod; 8. arc-shaped support plate; 9. second support rod; 10. rubber isolation ring; 11. return spring; 12. rubber pad; 13. handle.

[0018] like Figures 1 to 3 As shown: A cold-rolled coil core corner protector installation auxiliary tool includes a main shaft 1. A first flange 2 is fixedly connected to one end of the main shaft 1, a second flange 3 is fixedly connected to the main shaft 1, and a third flange 4 is movably sleeved on the other end of the main shaft 1. A return spring 11 is provided on the main shaft 1, located between the second flange 3 and the third flange 4. A lead screw 5 is provided at the end of the main shaft 1 connected to the third flange 4. A sleeve 6 is threadedly connected to the lead screw 5. A handle 13 is provided at one end of the sleeve 6. A rubber isolation ring 10 is provided at the end of the sleeve 6 that contacts the third flange 4. Several first support rods 7 are hinged to the first flange 2 and the second flange 3. One first support rod 7 is fixedly connected to the return spring 11. An arc-shaped support plate 8 is hinged to the other end of the first support rod 7. Several second support rods 9 are hinged to the third flange 4. The other end of the second support rod 9 is hinged to the arc-shaped support plate 8. A rubber pad 12 is provided on the arc-shaped support plate 8.

[0019] The implementation method of this embodiment is as follows: When it is necessary to install the corner protector of the steel coil core, first place the cold-rolled coil core corner protector installation auxiliary tool at the steel coil core. Then, the worker holds the handle 13 and rotates the sleeve 6 clockwise, so that the sleeve 6 pushes the third flange 4 to slide on the main shaft 1. At the same time, it drives the second support rod 9 to expand the arc support plate 8 outward, so that the rubber pad 12 contacts the inner ring of the steel coil, thereby expanding the inner ring of the steel coil. Then, the installation of the steel coil core corner protector can be carried out. After the corner protector is installed, the steel coil is bundled and packaged. After the packaging is completed, hold the handle 13 and rotate the sleeve 6 counterclockwise, so that the sleeve 6 moves away from the third flange 4. This will release the force of the second support rod 9. At the same time, under the action of the return spring 11, the first support rod 7 drives the arc support plate 8 to return to its original position. Then, the cold-rolled coil core corner protector installation auxiliary tool can be removed from the steel coil core.

[0020] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here.
