Description

Technical Field

[0001] The utility model relates to the field of hot rolling layer cold roller design, in particular to a hot rolling layer cold roller oil throwing protection device. Background Art

[0002] Because the dry oil overflowed from the roll neck of the first and second layer cooling groups, under the gauge and on the winding side guide rollers, it was thrown out by the high-speed rotating rollers (overflowed from the end of the water retaining cover roll and accumulated at the bottom of the roll neck), causing the strip to be contaminated by the dry oil, seriously affecting the product quality and image.

[0003] During the design, relevant protective devices are set for the cold rollers of the hot rolling layer to reduce the probability of the strip being contaminated by dry oil. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the dry oil overflowing from the roll neck is thrown out by the high-speed rotating roll, causing the strip steel to be contaminated by the dry oil, which seriously affects the product quality and image.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a hot-rolled layer cold roller oil-swinging protection device, comprising a roller, a bearing body and a bearing seat, the bearing body is sleeved and installed on the roller, the bearing seat is installed outside the bearing body, the inner ring of the bearing body is clamped with a first sleeve, the inner ring of the bearing body and the roller are clamped with a second sleeve, an end cover is installed outside the bearing seat, and a bell-shaped cover is installed on the other side of the bearing seat.

[0006] Furthermore, a water shield is installed outside the end cover, and a drainage hole is provided on the water shield.

[0007] Furthermore, a skeleton oil seal is engaged between the bell-shaped cover and the bearing body.

[0008] Furthermore, a first rib is clamped between the second sleeve and the end cover, and a second rib is clamped between the second sleeve and the end cover.

[0009] Furthermore, a dry oil collecting groove is provided on the end cover, and the dry oil collecting groove is located between the first rib and the second rib.

[0010] Preferably, the dry oil collection tank is externally connected to an oil discharge pipeline.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows:

[0012] By skimming off various components, the probability of the strip being contaminated by dry oil due to the dry oil overflowing from the roll neck being thrown out by the high-speed rotating roll (overflowing from the end side of the water retaining cover roll and accumulating at the bottom of the roll neck) can be reduced.

[0013] It also reduces the chances of affecting product quality and image, improves product quality, and increases production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1~Figure 5 As shown, the utility model is a hot-rolled layer cold roller oil-swing protection device, comprising a roller 1, a bearing body 2 and a bearing seat 3, the bearing body 2 is sleeved and installed on the roller 1, the bearing seat 3 is installed outside the bearing body 2, a first sleeve 4 is clamped on the inner ring of the bearing body 2, a second sleeve 5 is clamped between the inner ring of the bearing body 2 and the roller 1, an end cover 6 is installed outside the bearing seat 3, and a bell cover 7 is installed on the other side of the bearing seat 3.

[0021] A water retaining cover 8 is installed outside the end cover 6, and a drainage hole 9 is provided on the water retaining cover 8. A skeleton oil seal 10 is clamped between the bell cover 7 and the bearing body 2. A first bone 11 is clamped between the second sleeve 5 and the end cover 6. A second bone 12 is clamped between the second sleeve 5 and the end cover 6. A dry oil collecting groove 13 is provided on the end cover 6. The dry oil collecting groove 13 is located between the first bone 11 and the second bone 12, and an oil drainage pipe is designed at the bottom of the dry oil collecting groove 13.

[0022] During specific use: During the dry oil lubrication process, the dry oil overflows from the first bone 11 and the skeleton oil seal 10 and flows into the dry oil collecting groove 13 between the first bone 11 and the second bone 12. The dry oil collecting groove 13 is designed with an oil discharge pipe to gradually lead out the dry oil without overflowing from the end of the water retaining cover 8, and without accumulating at the lower part of the roller neck and being thrown out by the roller end.

[0023] It should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
