Description

Technical Field

[0001] The utility model relates to the technical field of strip steel processing equipment, and in particular to a strip steel anti-scratch and anti-break roller device. Background Technology

[0002] After the head coil of the combined rolling mill is fed to the welding machine through the unwinder, the strip will hit the upper roller system at the seven-roller processor position due to reasons such as the wave-shaped bulge in the plate shape during the speed-up process. On the one hand, it causes batch scratches on the upper surface of the strip, seriously affecting the quality and yield of the strip; on the other hand, it causes major accidents and safety hazards such as peeling or even breaking of the upper roller system. In addition, each time the roller peels, it is necessary to manually grind the upper roller. Because this position is narrow, you must reach in to grind it, which poses a great safety hazard. Therefore, an anti-grinding device for intermediate roller rolling is now provided. Contents of utility model

[0026] The lifting frame includes a first U-shaped rod 3 fixed on the outer wall of the rolling mill body 1, fixed sleeves 17 are welded on the opposite inner walls of the first U-shaped rod 3, a second U-shaped rod 2 is slidably inserted at the two fixed sleeves 17, a cross beam 10 is connected between the two fixed sleeves 17, an electric push rod 4 is installed at the top of the cross beam 10, and the top of the electric push rod 4 is connected to the middle of the lower end face of the horizontal section of the second U-shaped rod 2;

[0027] The heating component includes a fixed frame 11 fixed to the lower ends of the vertical segments on both sides of the second U-shaped rod 2.

[0028] Working principle: Control switches on the outer wall of the rolling mill body 1 are used to control the contraction of two hydraulic expansion rods 6. Subsequently, two support columns 5 rotate upward, causing the lower supporting roller 13 to move upward. The lower supporting roller 13 is used to lift the strip steel moved out from the outlet of the rolling mill body 1 upward, and the upper surface of the strip steel is brought into contact with the upper pressing roller 9. By clamping the strip steel with the upper pressing roller 9 and the lower supporting roller 13, the stability of the strip steel during movement is ensured, preventing the strip steel from hitting the roll system and being damaged, thereby preventing the strip steel from being scratched and preventing the roll system from peeling or even breaking. Additionally, the contraction of the electric push rod 4 can be controlled to drive the second U-shaped rod 2 and the fixed frame 11 downward, bringing the electric heating wire 12 closer to the strip steel. The electric heating wire 12 is turned on through the temperature control switch to heat the strip steel, which can reduce the influence of the strip steel and further reduce the risk of the strip steel scratching and peeling the roll system.
