Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rolling mill equipment, in particular to a rolling mill tail oil control device. Background Art
[0002] In the rolling production process of aluminum and aluminum alloys, full oil cooling and lubrication of rolls and plates are required. The main function of rolling oil is to cool, lubricate and clean rolls and aluminum strips. Due to the high-speed rotation of the rolls, the gap between the working rolls, the working rolls and the intermediate rolls, the ends of the intermediate rolls and the support rolls, and the roll surface will flow or bring rolling oil from the inlet side of the rolling mill to the outlet side. If these rolling oils drip onto the aluminum plate, the surface quality of the aluminum plate will be affected.
[0003] Most of the existing rolling mills use purging equipment to treat the rolling oil on the surface of the plate. However, at the tail section of the plate material, the burrs and warping of the tail part will scratch the working roll. At this time, the working roll needs to be opened to increase the gap between the working rolls to avoid scratching the working roll. However, after the gap is opened, a large amount of rolling oil will appear on the surface of the tail. At this time, the purging device cannot clean up the large amount of rolling oil, which affects the quality of the plate. Summary of the invention
[0004] In order to solve the problem that the existing purging equipment is unable to clean up a large amount of rolling oil appearing at the tail of the plate material, thus affecting the quality of the plate, the utility model proposes an oil control device for the tail of the rolling mill, which adjusts the upper and lower positions of the baffle roller through a power mechanism, and the power mechanism drives the baffle roller to move downward and contact the surface of the tail of the plate material. The oil-absorbing cotton on the outer surface of the baffle roller further removes the rolling oil that has not been cleaned up by the purging equipment, thereby improving the quality of the plate.
[0005] In order to achieve the above purpose, the technical solution of the utility model is:
[0006] A rolling mill tail oil control device includes a support frame body, the support frame body includes a first support body and two opposite second support bodies fixed on the first support body, the second support body is located on both sides of the first support body, a support roller is rotatably connected to the first support body, a power mechanism is fixed to the second support body, a through groove is opened on the second support body, a mounting seat is slidably connected in the through groove, a stop roller is installed in the mounting seat, and the power mechanism drives the mounting seat to move up and down in the through groove. The stop roller is located at the lower side of the support roller.
[0007] Furthermore, the retaining roller is wrapped with oil-absorbing cotton. The oil-absorbing cotton is fixed to the outside of the retaining roller by gluing. In addition, the oil-absorbing cotton can be fixed to the retaining roller by bolts by opening bolt holes on the retaining roller. At this time, the position of the bolt hole should be selected so that it is not located where the plate passes to avoid scratching the plate.
[0008] Furthermore, the front of the first support body is in a concave shape, the support roller is located in the concave part of the first support body, the front of the second support body is in an "L" shape, and a reinforcing plate is provided on the second support body. The two second support bodies are symmetrically arranged on the first support body.
[0009] Furthermore, the power mechanism is a cylinder, a piston rod of the cylinder extends into the through groove, and an end portion of the piston rod is fixedly connected to the mounting seat.
[0010] Furthermore, the power mechanism is an oil cylinder, a piston rod of the oil cylinder extends into the through groove, and an end portion thereof is fixedly connected to the mounting seat.
[0011] Furthermore, a limiting block is fixed on the side wall of the through slot, and a limiting groove matching the limiting block is provided on the mounting seat. When the power mechanism drives the mounting seat to move up and down, the limiting block cooperates with the limiting groove on the mounting seat to ensure the stability of the movement of the mounting seat.
[0012] Through the above technical scheme, the beneficial effect of the utility model is as follows: the utility model absorbs the rolling oil on the surface of the tail plate that has not been cleaned by the blowing equipment through the oil-absorbing cotton arranged on the outside of the stop roller. When there is only the tail of the plate and the gap between the working rollers is increased, the stop roller in the mounting seat is driven by the power mechanism to contact the upper surface of the plate. At this time, the stop roller blocks the rolling oil on the surface of the plate, and the oil-absorbing cotton arranged on the outside of the rear stop roller can absorb most of the rolling oil, thereby realizing the processing of the tail rolling oil and improving the quality of plate production.

DETAILED DESCRIPTION
[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:
[0020] like Figure 1 to Figure 5 As shown, this embodiment provides a rolling mill tail oil control device, including a support frame body, the support frame body includes a first support body 1 and two opposite second support bodies 2 fixed to the first support body 1, the second support body 2 is located on both sides of the first support body 1, the first support body 1 is rotatably connected with a support roller 3, and the second support body 2 is fixed with a power mechanism;
[0021] Specifically, the power mechanism is a cylinder 10, a piston rod 11 of the cylinder 10 extends into the through groove, and an end thereof is fixedly connected to the mounting seat 4, such as Figure 1 and Figure 2 It can be seen that a cylinder 10 is provided on the second supporting body 2, and the two cylinders 10 work synchronously to control the up and down movement of the mounting seat 4 in the through groove; in another possible implementation mode, the power mechanism is an oil cylinder, the piston rod of the oil cylinder extends into the through groove, and its end is fixedly connected to the mounting seat 4.
[0022] The second supporting body 2 is provided with a through slot, in which a mounting seat 4 is slidably connected, a retaining roller 5 is installed in the mounting seat 4, and a power mechanism drives the mounting seat 4 to move up and down in the through slot, and the retaining roller 5 is rotatably connected to the mounting seat 4.
[0023] Specifically, a limiting block 12 is fixed on the side wall of the through groove, and a limiting groove 8 matching the limiting block 12 is provided on the mounting seat 4. In this embodiment, limiting blocks 12 are fixed on both sides of the side wall of the through groove, and two limiting grooves 8 are provided on the mounting seat 4 to ensure the stability of the up and down movement of the mounting seat 4 in the through groove, and further ensure the stability of the up and down movement of the retaining roller 5.
[0024] The retaining roller 5 is wrapped with oil-absorbing cotton 6; Figure 2 and Figure 4 As shown, in this embodiment, as a preferred implementation mode, the oil-absorbing cotton 6 is square after being unfolded, and the two ends of the oil-absorbing cotton 6 are detachably connected to the stop roller 5 by gluing. In another implementation mode, the oil-absorbing cotton 6 can also be fixed to the stop roller 5 by bolts by opening bolt holes on the stop roller 5. At this time, the position of the bolt hole should be selected so that it is misaligned with the plate 13 to avoid scratching the plate 13.
[0025] As an implementation method, the front of the first support body 1 is in a concave shape, the support roller 3 is located in the concave part of the first support body 1, the front of the second support body 2 is in an "L" shape, and a reinforcing plate 7 is provided on the second support body 2.

[0026] When there is only the tail of the plate and the gap between the working rolls increases, the purging equipment in the rolling mill cannot clean up the large amount of rolling oil on the tail of the plate material. At this time, it is necessary to use the tail oil control device of the rolling mill to clean up the rolling oil that has not been cleaned up. The cleaning process is: the cylinders 10 on the two second support bodies are opened synchronously, and the piston rod 11 of the cylinder 10 drives the stop roller 5 in the mounting seat 4 to move toward the direction close to the plate 13. When the lower part of the stop roller 5 contacts the upper surface of the plate 13, the stop roller 5 blocks the rolling oil on the upper surface of the plate 13 on its inner side to prevent the rolling oil from remaining on the surface of the plate;
[0027] At this time, the oil-absorbing cotton 6 on the outside of the stop roller 5 absorbs most of the rolling oil, and the rolling oil that is not absorbed will flow into the working space. After the oil removal of the tail part is completed, the stop roller 5 can be lifted to its original position by the cylinder 10. When the oil-absorbing cotton 6 on the stop roller 5 has poor oil absorption capacity, the oil-absorbing cotton 6 can be replaced.
