Description

Technical Field

[0001] This utility model relates to the field of rolling technology, specifically to a lubrication mechanism for reducing rolling force and wear of rolling mill rolls. Background Technology

[0002] Rolling mills generally refer to equipment that completes the entire process of rolling production. Rolling mills can be divided into twin-roll and multi-roll rolling mills according to the number of rolls. A rolling mill is mainly composed of rolls, frame, roll gap adjustment device, roll temperature adjustment device, transmission device, lubrication system, control system and roll removal device. In addition to the main components and devices of ordinary rolling mills, precision rolling mills have added electro-hydraulic intelligent control devices to ensure rolling accuracy.

[0003] In existing technologies, a large portion of the high-pressure sprayed lubricating oil is flung off and ejected from the surface of the high-speed rotating rolls, failing to effectively enter the roll gap contact area. To ensure that enough lubricating oil is carried into the deformation zone, the system has to increase the spray flow rate and pressure, resulting in a significant increase in lubricating oil consumption and operating costs. At the same time, the splashed oil causes environmental pollution and increases the burden of subsequent recycling and treatment.

[0004] Therefore, a lubrication mechanism for reducing rolling force and wear of the rolls is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a lubrication mechanism for reducing rolling force and wear of rolls. It solves the problem that in existing technologies, a large portion of the high-pressure sprayed lubricating oil is flung off and ejected from the surface of the high-speed rotating roll, failing to effectively enter the roll gap contact area. To ensure sufficient lubricating oil is carried into the deformation zone, the system has to increase the spray flow rate and pressure, resulting in a significant increase in lubricating oil consumption and operating costs. At the same time, the splashed oil causes environmental pollution, increasing the burden of subsequent recycling and treatment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a rolling mill body, wherein a lubrication mechanism is mounted on the top of the rolling mill body, and a lowering mechanism is mounted on the top of the rolling mill body; The lowering mechanism includes a fixed plate, which is fixedly connected to the upper surface of the mill body.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example See Figures 1-5 This embodiment provides a lubrication mechanism for reducing rolling force and wear of rolling mills, including a mill body 1, a lubrication mechanism 2 mounted on the top of the mill body 1, and a lowering mechanism 3 mounted on the top of the mill body 1. The lowering mechanism 3 includes a fixed plate 312, which is fixedly connected to the upper surface of the mill body 1. A rotating rod is rotatably connected to the side of the fixed plate 312 via a bearing. A first ring 36 is fixedly sleeved on the outer wall of the arc-shaped surface of the rotating rod. A second ring 310 is slidably connected to the outer wall of the arc-shaped surface of the rotating rod. A first connecting rod 37 is hinged to the outer wall of the arc-shaped surface of the first ring 36. A counterweight ball 38 is hinged to the side of the first connecting rod 37. A second connecting rod 39 is hinged to the side of the counterweight ball 38. A connecting plate 31 is fixedly connected to the lower surface of the mill body 1. A slider 32 is slidably connected to the inner wall of the connecting plate 31. An extrusion block 311 is fixedly connected to the upper surface of the slider 32. A connecting block 34 is fixedly connected to the lower surface of the slider 32. Several brush bristles 35 are fixedly connected to the lower surface of the connecting block 34.

[0019] When the motor 25 is started, it drives the rotating rod to rotate, which in turn drives the first ring 36 to rotate. The first ring 36 drives the first connecting rod 37 to rotate, and the first connecting rod 37 drives the counterweight ball 38 to rotate. The centrifugal force generated by the rotation of the rotating rod causes the counterweight ball 38 to move the second connecting rod 39 to the left. The second connecting rod 39 then drives the second ring 310 to move to the left. At the same time, during the rotation, the counterweight ball 38 will press the inclined surface of the extrusion block 311, causing the extrusion block 311 to move to the bottom. As the extrusion block 311 descends, it presses the spring 33, causing the extrusion block 311 to descend. The descending slide block 32 then causes the connecting block 34 to descend, and the connecting block 34 causes the brush 35 to descend. In conjunction with the lubrication mechanism 2, the brush 35 evenly spreads the lubricating oil sprayed by the lubrication mechanism 2 onto the surface of the upper roll inside the mill body 1. When the motor 25 is turned off, the counterweight ball 38 is reset through the torsion spring at the hinge point of the first connecting rod 37 and the second connecting rod 39. After the lubricating oil is sprayed onto the upper roll, it drips or flows downwards due to gravity before entering the roll gap as the roll rotates. This causes some lubricating oil to be lost before reaching the contact area, reducing utilization efficiency. At the same time, the flow causes uneven oil film on the roll surface. The rotating bristles 35 evenly spread and press the oil into the tiny pits on the roll surface, ensuring that more and more even lubricating oil is delivered to the roll gap. The lower roll does not have this problem. The lubricating oil sprayed onto the lower roll will naturally gather in the roll gap area under the action of gravity, and may even be supported by the rolled workpiece, making it less likely to be lost. Therefore, the lower roll does not have such an urgent need for bristles 35, so bristles 35 are only installed on the upper roll. At the same time, the bristles 35 are only lowered during lubrication. During the rolling process, especially when the strip is threaded, tailing, or steel piling occurs, the thin material of the broken strip or the fragments at the head and tail are easily splashed. These strip-shaped or sheet-shaped metal scraps are very easy to get tangled on the brush roll, and the more they get tangled, the more likely they are to be damaged by the bristles 35, eventually leading to the scrapping of the brush roll.

[0020] The extrusion block 311 is trapezoidal in shape, and a spring 33 is installed at the bottom of the extrusion block 311. Torsion springs are provided at the hinge points of the first connecting rod 37 and the second connecting rod 39 with the counterweight ball 38.

[0021] Spring 33 is fixedly connected to the lower surface of extrusion block 311, and the end of spring 33 away from extrusion block 311 is fixedly connected to the upper surface of connecting plate 31.

[0022] The first connecting rod 37, the counterweight ball 38, and the second connecting rod 39 form a group, and there are two groups in total.

[0023] See Figures 1-3 The lubrication mechanism 2 includes a lubricating oil tank 21, which is fixedly connected to the upper surface of the mill body 1. A peristaltic pump body 22 is fixedly connected to the upper surface of the mill body 1. A first connecting pipe 24 is fixedly connected to the front of the peristaltic pump body 22, and a second connecting pipe 23 is fixedly connected to the side of the peristaltic pump body 22.

[0024] A support rod 26 is fixedly connected to the side of the mill body 1. A cavity 27 is fixedly connected to the side of the support rod 26. A nozzle 28 is fixedly connected to the side of the cavity 27. The end of the first connecting pipe 24 away from the peristaltic pump body 22 is fixedly connected to the outer wall of the lubricating oil tank 21. The end of the second connecting pipe 23 away from the peristaltic pump body 22 is fixedly connected to the top of the cavity 27. A motor 25 is fixedly connected to the upper surface of the mill body 1.

[0025] The rotating rod moves through the fixed plate 312, with the extended end of the rotating rod extending towards the front of the fixed plate 312. The extended end of the rotating rod is fixedly connected to the output end of the peristaltic pump body 22, and the end of the rotating rod away from the peristaltic pump body 22 is fixedly connected to the front of the output end of the motor 25.

[0026] While the motor 25 drives the rotating rod to rotate, the rotating rod drives the output end of the peristaltic pump body 22 to rotate. The peristaltic pump body 22 draws lubricating oil from the lubricating oil tank 21 through the first connecting pipe 24, and then delivers the lubricating oil to the cavity 27 through the second connecting pipe 23. The lubricating oil is then delivered to the nozzle 28 through the cavity 27, and finally sprayed with lubricating oil onto the upper and lower rolls inside the rolling mill body 1 through the nozzle 28.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
