Description

Technical Field

[0001] The utility model relates to the field of steel rolling equipment, in particular to a cooling bed for reducing scratches on steel bars. Background Art

[0002] After the steel bars are rolled by a rolling mill, they need to be placed on a cooling bed for cooling. During the transportation process of the steel bars, the steel bars have multiple sliding frictions with the cooling bed, which easily cause scratches on the surface of the steel bars and affect the surface quality of the steel bars. Therefore, it is particularly necessary to develop a cooling bed for steel bars that can reduce scratches on the surface of the steel bars and improve the surface quality of the steel bars. Summary of the Invention

[0004] The adopted technical solution is as follows:

[0005] A cooling bed for reducing scratches on steel bars, including a frame, on which a steel bar separating mechanism, a braking plate mechanism and a straightening plate are arranged. The braking plate mechanism is connected end to end with the steel bar separating mechanism and the straightening plate. The steel bar separating mechanism includes multiple sections of separating steel plates, and the separating steel plates are all slidably connected to the frame. The frame is provided with a first lifting mechanism connected to the separating steel plates. Multiple first guide rollers are arranged at the upper ends of the separating steel plates. The braking plate mechanism includes a braking plate, and the braking plate is slidably connected to the frame. The frame is provided with a second lifting mechanism connected to the braking plate. Multiple second vertical rollers are arranged on the side surface of the braking plate. Multiple wear-resistant strips are arranged on the side surface and the upper end surface of the straightening plate.

[0006] Preferably, multiple wear-resistant strips are arranged on the upper end surface of the braking plate.

[0007] Preferably, the first lifting mechanism includes a first telescopic cylinder, the first telescopic cylinder is rotatably connected to the frame, and the upper end of the first telescopic cylinder is rotatably connected to the separating steel plate.

[0008] Preferably, the second lifting mechanism includes a second telescopic cylinder, the second telescopic cylinder is rotatably connected to the frame, an L-shaped frame is rotatably arranged on the frame, the L-shaped frame is rotatably connected to the second telescopic cylinder, a transmission arm is rotatably connected to the L-shaped frame, and the upper end of the transmission arm is rotatably connected to the braking plate.

[0009] Preferably, the wear-resistant strips are made of tungsten carbide.

[0010] Compared with the prior art, the beneficial effects are as follows:

[0011] When the utility model separates steel bars, the first guide roller on the steel separating plate is used to contact the steel bars, so that the sliding friction between the steel bars and the steel separating plate is converted into rolling friction, reducing the scratches on the surface of the steel bars. The second lifting mechanism controls the brake plate to lower, and the steel separating plate sends the steel bars into the brake plate. The steel bars contact the second vertical roller, so that the sliding friction between the steel bars and the brake plate is converted into rolling friction, reducing the scratches on the surface of the steel bars. After the steel bars enter the straightening plate, multiple wear-resistant strips contact the steel bars to reduce the scratches on the steel bars and improve the surface quality of the steel bars.

[0016] The following further describes the utility model with reference to specific embodiments, as Figures 1 to 3 shown:

[0017] Embodiment 1: A cooling bed for reducing scratches on steel bars, including a frame 1. A steel separating mechanism, a brake plate mechanism and a straightening plate 11 are arranged on the frame 1. The brake plate mechanism is connected end to end with the steel separating mechanism and the straightening plate 11. The steel separating mechanism includes multiple sections of steel separating plates 2. The steel separating plates 2 are all slidably connected to the frame 1. The frame 1 is provided with a first lifting mechanism connected to the steel separating plates 2. The first lifting mechanism controls the steel separating plates 2 to slide vertically along the frame 1.

[0018] Multiple first guide rollers 4 are arranged at the upper ends of the steel separating plates 2. When the steel bars move on the steel separating plates 2, the steel bars contact the first guide rollers 4, so that the sliding friction between the steel bars and the steel separating plates 2 is converted into rolling friction, reducing the scratches on the surface of the steel bars.

[0019] The brake plate mechanism includes a brake plate 5. The brake plate 5 is slidably connected to the frame 1. The frame 1 is provided with a second lifting mechanism connected to the brake plate 5. Multiple second vertical rollers 10 are arranged on the side surface of the brake plate 5. When the steel bars are lifted, the steel bars contact the second vertical rollers 10, so that the sliding friction between the steel bars and the brake plate 5 is converted into rolling friction, reducing the scratches on the surface of the steel bars.

[0020] On the side and upper end face of the throwing straight plate 11, a plurality of wear-resistant strips 12 are provided. The wear-resistant strips 12 are fixedly connected to the throwing straight plate 11 by countersunk bolts. The wear-resistant strips 12 reduce the direct contact between the steel bars and the throwing straight plate 11, and reduce the scratches on the steel bars through the wear-resistant strips 12 with a hardness smaller than that of the steel bars. When the wear-resistant strips 12 are worn too much, new wear-resistant strips 12 can be replaced by removing the countersunk bolts.

[0021] Embodiment 2: A cooling bed for reducing scratches on steel bars, comprising a frame 1. A steel distributing mechanism, a braking plate mechanism and a throwing straight plate 11 are arranged on the frame 1. The braking plate mechanism is connected end to end with the steel distributing mechanism and the throwing straight plate 11. The steel distributing mechanism includes multiple sections of steel distributing plates 2, and the steel distributing plates 2 are all slidably connected to the frame 1. The frame 1 is provided with a first lifting mechanism connected to the steel distributing plates 2. The first lifting mechanism includes a first telescopic cylinder 3. The first telescopic cylinder 3 is rotatably connected to the frame 1, and the upper end of the first telescopic cylinder 3 is rotatably connected to the steel distributing plate 2. The first lifting mechanism controls the steel distributing plate 2 to slide vertically along the frame 1.

[0022] A plurality of first guide rollers 4 are arranged at the upper ends of the steel distributing plates 2. When the steel bars move on the steel distributing plates 2, the steel bars contact the first guide rollers 4, converting the sliding friction between the steel bars and the steel distributing plates 2 into rolling friction, and reducing the scratches on the surface of the steel bars.

[0023] The braking plate mechanism includes a braking plate 5. The braking plate 5 is slidably connected to the frame 1. The frame 1 is provided with a second lifting mechanism connected to the braking plate 5. The second lifting mechanism includes a second telescopic cylinder 6. The second telescopic cylinder 6 is rotatably connected to the frame 1. An L-shaped frame 8 is rotatably arranged on the frame 1. The L-shaped frame 8 is rotatably connected to the second telescopic cylinder 6. The L-shaped frame 8 is rotatably connected to a transmission arm 9. The upper end of the transmission arm 9 is rotatably connected to the braking plate 5. The second lifting mechanism controls the lifting of the braking plate 5.

[0024] A plurality of second vertical rollers 10 are arranged on the side of the braking plate 5. When the steel bars are lifted, the steel bars contact the second vertical rollers 10, converting the sliding friction between the steel bars and the braking plate 5 into rolling friction, and reducing the scratches on the surface of the steel bars.

[0025] On the side and upper end face of the throwing straight plate 11, a plurality of wear-resistant strips 12 are provided. The wear-resistant strips 12 are fixedly connected to the throwing straight plate 11 by countersunk bolts. A plurality of wear-resistant strips 12 are arranged on the upper end face of the braking plate 5. The wear-resistant strips 12 are made of tungsten carbide. The wear-resistant strips 12 arranged on the braking plate 5 are fixedly connected to the braking plate 5 by countersunk bolts. The wear-resistant strips 12 reduce the direct contact between the steel bars and the throwing straight plate 11, and reduce the scratches on the steel bars through the wear-resistant strips 12 with a hardness smaller than that of the steel bars. When the wear-resistant strips 12 are worn too much, new wear-resistant strips 12 can be replaced by removing the countersunk bolts.

[0026] The specific working process is as follows: When the rolled steel bars enter the cooling bed, the first lifting mechanism controls the lowering of the dividing steel plate 2, and the steel bars enter onto the dividing steel plate 2. The first guide roller 4 on the dividing steel plate 2 contacts the steel bars, converting the sliding friction between the steel bars and the dividing steel plate 2 into rolling friction. The second lifting mechanism controls the lowering of the braking plate 5, and the dividing steel plate 2 sends the steel bars into the braking plate 5. During this process, the steel bars contact the second vertical roller 10, converting the sliding friction between the steel bars and the braking plate 5 into rolling friction, reducing scratches on the surface of the steel bars. After the steel bars enter the straightening plate 11, multiple wear-resistant strips 12 contact the steel bars to reduce scratches on the steel bars, and then enter the cooling bed to cool the rolled steel bars.
