Abstract
Description
Technical Field
[0001] The utility model relates to the field of steel, in particular to a steel plate with high flatness. Background Art
[0002] A steel plate is a flat steel product cast from molten steel and pressed after cooling. It is flat and rectangular, and can be directly rolled or cut from a wide steel strip. Steel plates are classified by thickness: thin steel plates are less than 4 mm (the thinnest is 0.2 mm), medium-thick steel plates are 4 to 60 mm, and extra-thick steel plates are 60 to 115 mm.
[0003] Steel plates are classified by rolling into hot-rolled and cold-rolled. The width of thin plates is 500 to 1500 mm; the width of thick plates is 600 to 3000 mm. Thin plates are classified by steel type into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, industrial pure iron thin plates, etc.; classified by professional use into oil drum plates, enamel plates, bulletproof plates, etc.; classified by surface coating into galvanized thin plates, tin-plated thin plates, lead-plated thin plates, plastic composite steel plates, etc.
[0004] When a steel plate is produced, an important parameter is its flatness, which needs to meet the national standard requirements. However, its flatness is very easy to change during transportation, resulting in unqualified steel plates. Most of the existing steel plates lack corresponding protection measures on their surfaces. Therefore, they are very easy to be worn or corroded during transportation, resulting in a decrease in their flatness and affecting their actual use performance.
[0005] Therefore, it is necessary to provide a new steel plate with high flatness to solve the above technical problems. Summary of the Utility Model
[0006] To solve the above technical problems, the utility model provides a steel plate with high flatness, which solves the problem that most of the existing steel plates lack corresponding protection measures on their surfaces. Therefore, they are very easy to be worn or corroded during transportation, resulting in a decrease in their flatness and affecting their actual use performance.
[0007] The steel plate with high flatness provided by the utility model includes a plate body. A U-shaped frame is arranged on one side of the plate body. A protective cover is fixed on one side of the U-shaped frame. One side of the inner surface of the protective cover is provided with a female magic tape, and the other side is provided with a male magic tape. A plurality of fixing components are arranged between the U-shaped frame and the plate body.
[0008] In a preferred embodiment, the fixing component includes a threaded ejector rod and a pressing plate. One end of the threaded ejector rod penetrates through the U-shaped frame and is fixed with the pressing plate, and the other end of the threaded ejector rod is fixed with a hexagonal block.
[0009] In a preferred embodiment, a silica gel pad is arranged on the surface of the pressing plate.
[0010] In a preferred embodiment, support plates are fixed on both sides of the protective cover. A pair of first limit seats and a pair of second limit seats are respectively fixed on the support plates and the U-shaped frame, and a spring is fixed between the first limit seat and the second limit seat.
[0011] In a preferred embodiment, the surface of the spring is treated against rust.
[0012] In a preferred embodiment, the protective cover is made of Cordura nylon material.
[0013] Advantages of the utility model:
[0014] 1. By arranging a protective cover outside the steel plate, this structure can prevent the surface of the steel plate from rusting or wearing during the transfer process, thereby ensuring that the surface flatness meets the specifications.
[0015] 2. During the installation of the U-shaped frame, only need to fix the plate body inside the U-shaped frame, then fully unfold the protective cover so that the plate body is completely inside the U-shaped frame, and finally connect the male and female magic tapes together to complete the installation of the protective cover. When disassembling, separate the male and female magic tapes. Under the action of the spring, it can assist the staff to retract the protective cover. Finally, loosen the threaded ejector rod for fixing to complete the disassembly of the U-shaped frame. In summary, the device has a simple structure, is easy to use, and can fully protect the surface of the steel plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The present utility model will be further described below in conjunction with the drawings and embodiments.
[0022] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , where Figure 1 is the overall structural schematic diagram of the steel plate with high flatness provided by the present utility model; Figure 2 is the structural schematic diagram of the protective cover provided by the present utility model; Figure 3 is Figure 2 the enlarged structural schematic diagram of A shown in; Figure 4 is the structural schematic diagram of the fixing component provided by the present utility model.
[0023] In the specific implementation process, as Figure 1-Figure 4 shown, it includes a plate body 1, a U-shaped frame 2 is arranged on one side of the plate body 1, a protective cover 3 is fixed on one side of the U-shaped frame 2, a female magic tape 4 is arranged on one side inside the protective cover 3, and a male magic tape 5 is arranged on the other side. A plurality of fixing components 14 are arranged between the U-shaped frame 2 and the plate body 1. The fixing component 14 includes a threaded ejector rod 6 and a pressing plate 7. One end of the threaded ejector rod 6 penetrates through the U-shaped frame 2 and is fixed with the pressing plate 7. A hexagonal block 8 is fixed at the other end of the threaded ejector rod 6. During the installation of the U-shaped frame 2, only need to place one side of the plate body 1 inside the U-shaped frame 2, and then use a wrench to rotate the hexagonal block 8 to drive the threaded ejector rod 6 to move. The pressing plate 7 can be driven to move towards the plate body 1 through the threaded ejector rod 6, and finally the U-shaped frame 2 is fixed on one side of the plate body 1. A silica gel pad 9 is arranged on the surface of the pressing plate 7. By arranging the silica gel pad 9, the surface of the plate body 1 can be protected, and stress deformation of the steel plate surface caused by the pressing plate 7 can be avoided.
[0024] Support plates 10 are fixed on both sides of the protective cover 3. A pair of first limit seats 11 and a pair of second limit seats 12 are respectively fixed on the support plates 10 and the U-shaped frame 2, and a spring 13 is fixed between the first limit seat 11 and the second limit seat 12. When disassembly is required, separate the male and female magic tapes. Under the action of the spring 13, it can assist the staff to retract the protective cover 3. Finally, loosen the threaded ejector rod 6 for fixing to complete the disassembly work of the U-shaped frame 2. The surface of the spring 13 is treated with anti-corrosion to increase its service life.
[0025] The protective cover 3 is made of Cordura nylon material. Cordura nylon material is a lightweight and high-strength fabric, which is very wear-resistant and has a long service life.

[0027] During the installation of the U-shaped frame 2, only one side of the plate body 1 needs to be placed inside the U-shaped frame 2, and then use a wrench to rotate the hexagonal block 8 to drive the threaded ejector rod 6 to move. Through the threaded ejector rod 6, the pressing plate 7 can be driven to move towards the plate body 1, and finally the U-shaped frame 2 is fixed on one side of the plate body 1. Then, fully unfold the protective cover 3 so that the entire plate body 1 is located inside the U-shaped frame 2. Finally, connect the male and female magic tapes together to complete the installation work of the protective cover 3;
