Description

Technical Field

[0001] The utility model relates to a strip steel squeezing roller pressure adjustment mechanism, belonging to the technical field of reversible cold rolling mill equipment in the metallurgical industry. Background Art

[0002] The reversible cold rolling mill is equipped with a strip surface squeezer before and after each roll to squeeze out any residual emulsion on the strip surface. The squeezer comprises an upper squeezer roller and a lower squeezer roller, which are eccentrically pressed down with an eccentricity of approximately 75 mm and an overlap of approximately 12.8 mm. The squeezer rollers are primarily pressed down by lifting cylinders installed at both ends of the squeezer rollers. However, since the lift cylinders have a fixed stroke, the pressure on the strip varies with the thickness of the rolled strip. Excessive pressure on the strip can create an illusion of strip shape, affecting the operator's judgment, while excessively low pressure can result in poor strip surface squeeze-out. Therefore, a strip squeezer roller pressure adjustment mechanism is needed that can adapt to strips of varying thicknesses, achieve strip surface cleanliness, and not affect the operator's judgment. Utility Model Content

[0003] The purpose of the utility model is to provide a strip steel squeezing roller pressure adjustment mechanism that can adapt to strip steel of different thicknesses, ensure the cleanliness of the strip steel surface, and not affect the operator's judgment of the strip steel plate shape, thereby solving the problems existing in the background technology.

[0004] The technical solution of the utility model is:

[0005] A strip squeezing roller pressure adjustment mechanism comprises an upper squeezing roller, a lower squeezing roller, a guide column and a lifting cylinder. The upper squeezing roller and the lower squeezing roller are eccentrically arranged up and down. Guide columns and lifting cylinders are provided between the bearing seats at both ends of the upper squeezing roller and the lower squeezing roller. The cylinder body of the lifting cylinder is fixed on the bearing seat of the lower squeezing roller. The cylinder rod of the lifting cylinder is drivingly connected to the bearing seat of the upper squeezing roller. An adjustment bolt is also provided on the bearing seat of the lower squeezing roller.

[0006] The adjusting bolt on the lower squeezing roller bearing seat is vertical.

[0007] The adjusting bolt on the lower squeezing roller bearing seat is provided with a locking nut.

[0008] The adjusting bolt on the bearing seat of the lower squeezing roller is matched with the bearing seat of the upper squeezing roller.

[0009] By adopting the utility model, the height of the top surface of the adjustment bolt is controlled according to the thickness of the finished steel strip. When the upper squeeze roller is pressed down, the bearing seat of the upper squeeze roller is pressed on the adjustment bolt, thereby controlling the travel range of the lifting cylinder and fixing the overlap amount of the upper and lower squeeze rollers.

[0010] The beneficial effects of the utility model are: it can adapt to strip steels of different thicknesses, ensure the cleanliness of the strip steel surface, and does not affect the operator's judgment on the strip steel plate shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In the figure: upper squeeze roller 1, lower squeeze roller 2, guide column 3, adjustment bolt 4, lifting cylinder 5, bearing seat 6, locking nut 7, strip steel 8. DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings and examples.

[0015] Refer to the attached Figs. 1-2 A strip squeezing roller pressure adjustment mechanism comprises an upper squeezing roller 1, a lower squeezing roller 2, a guide column 3 and a lifting cylinder 5. The upper squeezing roller 1 and the lower squeezing roller 2 are eccentrically arranged up and down. Guide columns 3 and lifting cylinders 5 are provided between the bearing seats at both ends of the upper squeezing roller 1 and the lower squeezing roller 2. The cylinder body of the lifting cylinder 5 is fixed on the bearing seat of the lower squeezing roller 2. The cylinder rod of the lifting cylinder 5 is drivingly connected to the bearing seat of the upper squeezing roller 1. An adjusting bolt 4 is also provided on the bearing seat of the lower squeezing roller 2.

[0016] In this embodiment, refer to the attached Figs. 1-2 The squeeze rollers are arranged in two pairs, the diameter of the squeeze rollers is 220mm, and the centers of the two squeeze rollers are as follows: Fig. 2 As shown, the eccentric pressure is 75mm, and the overlap of the upper and lower paired squeeze rollers is 12.8mm. The pressure of the upper squeeze roller 1 is based on the lifting cylinder 5 installed on the bearing seats at both ends of the squeeze roller. Since the stroke of the lifting cylinder 5 is fixed, it cannot adapt to finished strip steel of different thicknesses. Therefore, adjusting bolts 4 and locking nuts 7 are installed on the bearing seats at both ends of the lower squeeze roller 2. There are four adjusting bolts 4. After adjusting the height with the adjusting bolts 4, the height is fixed by locking the adjusting nuts 7.

[0017] According to the different thickness of the finished strip steel, the height of the adjusting bolt 4 is controlled. When the upper squeeze roller is pressed down, the bearing seat of the upper squeeze roller is pressed on the four adjusting bolts 4, thereby controlling the stroke range of the lifting cylinder 5 and fixing the overlap amount of the upper and lower squeeze rollers.

[0018] In actual production, the emulsion level on the strip surface is tracked to adjust the overlap of the squeeze rollers and the pressure reduction based on the strip thickness to prevent excessive strip pressure from causing false strip shape. Experiments have yielded adjustment data for squeeze pressure and overlap for finished strips of varying thicknesses, as shown in Table 1.
