Description

Technical field:

[0002] The utility model relates to an adjusting gasket structure and a mechanism for controlling the splashing of rolling oil on the surface of a cold rolling mill strip. Background technology:

[0004] When a cold rolling mill is rolling strips (such as aluminum strips), rolling oil will be sprayed at the inlet of the cold rolling mill to lubricate and cool the strips. However, no rolling oil should splash onto the strip surface at the outlet of the cold rolling mill to avoid affecting the surface quality of the strips in subsequent processes.

[0005] Therefore, it is necessary to install an oil baffle plate on the outlet side of the cold rolling mill. At present, the oil baffle plate is fixedly connected to the first end of the guide rod, the second end of the guide rod is hinged to the first end of the swing arm, and the second end of the swing arm is rotatably hinged on the frame of the cold rolling mill. A hydraulic cylinder is also installed on the frame of the cold rolling mill, and the free end of the telescopic rod of the hydraulic cylinder is hinged to the middle part of the swing arm. The oil baffle plate is controlled to be in the working station or the maintenance station by the extension and contraction of the telescopic rod of the hydraulic cylinder (at the working station, the oil baffle plate is used to block the oil, and at the maintenance station, the oil baffle plate is greatly away from the rolling roller, which is convenient for replacing the oil baffle plate). However, when processing strips of different thicknesses or replacing rolls of different diameters, it is necessary to adjust the gap between the oil baffle plate and the rolling roller to avoid rolling oil splashing onto the surface of the strip. At present, it is very cumbersome to adjust or replace the oil baffle plate, and the adjustment or replacement time is long, which affects production.

[0006] Currently, a Chinese patent "Multifunctional and easy-to-place oil baffle" with publication number CN111150315A has been retrieved, which includes a handle, a first hinged seat is fixedly welded at the bottom end of the handle, a telescopic rod is hinged on the first hinged seat by bolts, a second hinged seat is fixedly welded at the bottom end of the telescopic rod, a mounting seat is hinged on the second hinged seat by bolts, an oil baffle body is riveted to the mounting seat by rivets, a pad is fixedly welded on the middle part of one side of the oil baffle body, and a fan is also included. This invention cannot be applied in a cold rolling mill to adjust the gap between the oil baffle and the roller, and cannot control the rolling oil from splashing onto the surface of the cold rolling mill strip. Summary of the invention:

[0008] In view of this, the purpose of the utility model is to provide an adjusting gasket structure and a mechanism for controlling the splashing of rolling oil on the surface of the cold rolling mill strip. The adjusting gasket structure and the mechanism for controlling the splashing of rolling oil on the surface of the cold rolling mill strip are reasonably designed, which is conducive to adjusting the gap between the oil baffle and the roller, and avoiding the splashing of rolling oil onto the surface of the cold rolling mill strip.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as commonly understood by ordinary technicians in the technical field to which the present application belongs.

[0028] The utility model discloses a mechanism for controlling rolling oil splashing on the surface of a cold rolling mill strip, comprising a cold rolling mill 1 and a rolling roller 2 arranged on the cold rolling mill 1, an oil baffle plate 3 for preventing rolling oil splashing is arranged on the side of the rolling roller 2, the oil baffle plate 3 is fixedly connected to the first end of a guide rod 4, the second end of the guide rod 4 is hinged to the first end of a swing arm 5, wherein a track 8 for sliding the limiting guide rod is arranged on the frame, the second end of the swing arm 5 is rotatably hinged on the frame of the cold rolling mill, a hydraulic cylinder 6 is also installed on the frame of the cold rolling mill, the free end of a telescopic rod 7 of the hydraulic cylinder 6 is hinged to the middle part of the swing arm, an adjusting gasket structure A is arranged on the hydraulic cylinder, when the telescopic rod 7 of the hydraulic cylinder 6 is extended, the swing arm 5 drives the guide rod 4 and the oil baffle plate 3 away from the rolling roller 2, and when the telescopic rod 7 of the hydraulic cylinder 6 is retracted, the swing arm 5 drives the guide rod 4 and the oil baffle plate 3 close to the rolling roller 2.

[0029] The utility model comprises a regulating gasket structure A including a thin gasket A1 and a recessed groove A2 provided on one side of the thin gasket, the thin gasket and the recessed groove are coaxially arranged in a circular shape (of course a square shape is also acceptable), the recessed groove A2 is sleeved on a hydraulic cylinder end 601 (the hydraulic cylinder end 601 is a position on the hydraulic cylinder body close to the telescopic rod 7), the thin gasket is provided with a through groove A3 for the telescopic rod of the hydraulic cylinder to pass through, the through groove A3 extends from the outer peripheral wall of the thin gasket A1 beyond its central part, the through groove is U-shaped, the bottom of the through groove is arc-shaped, the through groove is matched with the telescopic rod of the hydraulic cylinder, so that the thin gasket A1 will not touch the telescopic rod.

[0030] The thin gasket A1 is threadedly connected with a tightening bolt A4 which penetrates into the recessed groove A2 from its outer wall. The telescopic rod 7 of the hydraulic cylinder passes through the through groove A3. The inner end of the tightening bolt is pressed against the outer peripheral surface of the hydraulic cylinder end 601 to achieve the tightening of the thin gasket A1 and the hydraulic cylinder end 601.

[0031] When controlling the gap between the oil baffle and the roller, thin gaskets A1 of different thicknesses are selected (the depth of the sink groove A2 is a fixed value). The thickness of the thin gasket A1 minus the depth of the sink groove A2 is the basis for selecting the gap between the oil baffle and the roller. When rolling aluminum strips of different thicknesses and using rollers of different diameters, replacing thin gaskets A1 of different thicknesses can meet the function of adjusting the gap between the oil baffle and the roller.

[0032] The working principle of the mechanism of the utility model for controlling the splashing of rolling oil on the surface of the strip of the cold rolling mill is that a groove is placed on the end head of the hydraulic cylinder and a tightening bolt is used to tighten the groove so that the inner end of the tightening bolt is pressed against the outer peripheral surface of the end head of the hydraulic cylinder, thereby realizing the tightening of the thin gasket and the end head of the hydraulic cylinder. When the telescopic rod of the hydraulic cylinder retracts, it is resisted by the thin gasket, so that the retraction stroke of the telescopic rod is limited, that is, the gap between the oil baffle plate and the roller is controlled. When a different gap between the oil baffle plate and the roller is required, thin gaskets of different thicknesses can be replaced. The replacement of thin gaskets of different thicknesses is convenient and quick, and the replacement cost is low.

[0033] The preferred embodiments listed above further illustrate the purpose, technical solutions and advantages of the utility model in detail. It should be understood that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
