Description

Technical Field

[0001] The utility model relates to the technical field of strip steel rolling mills, in particular to an oil-slinging prevention device for a support roller. Background Art

[0002] A rolling mill is a machine that plastically deforms metal materials. Its operating principle is to forcefully squeeze metal materials, such as steel, through the rotation of two or more rollers, changing their cross-sectional shape and size. During this process, the rollers move according to a specific pattern, squeezing the metal material, gradually making it stronger and more durable, thereby achieving higher levels of processing and quality. Rolling mills can be divided into various types, such as plate mills, strip mills, bar mills, and tube mills, depending on their application and operating principles.

[0003] Among them, the strip mill is a production equipment that rolls steel ingots or billets into steel strips. It has the advantages of high productivity, wide variety, strong production continuity, and easy mechanical automation, and plays an important role in the metallurgical industry.

[0004] However, when the existing strip mill is in use, due to the lack of a protective mechanism on the bottom support rollers, oil stains are easily dripped onto the locking nuts and half-circlips on the operating side of the bottom support rollers when the strip passes through the mill. As the support rollers rotate at high speed, the oil stains will splash, causing the surrounding mill surfaces to be easily corroded by the oil stains, and also polluting the surrounding environment.

[0005] Therefore, it is urgent to redesign a new support roller anti-oil throwing device to solve the above problems. Utility Model Content

[0033] See also Figures 1 to 8 The utility model provides a support roller anti-oil-slinging device, which includes a support roller 1 and a pair of protective covers 2.

[0034] Wherein, both ends of the support roller 1 are connected to a bearing seat 101 , and the bearing seat 101 is used to install the support roller 1 .

[0035] Preferably, the support roller 1 and the bearing seat 101 used in this application are both existing technologies, and the connections between the various components of the support roller 1 and the bearing seat 101 are also existing technologies. Therefore, their connections and working principles will not be described in detail here.

[0036] In addition, a fixing member 102 is fixedly connected to the bearing seat 101 . More specifically, the fixing member 102 is arranged on the end cover of the bearing seat 101 . The end cover is circumferential. The fixing member 102 is used to fix the protective cover 2 .

[0037] Specifically, the fixing member 102 is threadedly connected to the bearing seat 101 to facilitate replacement of the fixing member 102 . The fixing member 102 is 30 mm long and is used to fix the protective cover 2 .

[0038] See also Figures 1 to 8 A pair of protective covers 2 are installed on the bearing seat 101 and surround the two ends of the support roller 1 respectively. The protective covers 2 are used to block oil stains, so that the oil stains are not easy to drip to the ends of the support roller 1. When the support roller 1 rotates at high speed, the oil stains are not easy to splash around, thereby reducing the probability of surrounding equipment being corroded by oil stains, and also reducing pollution to the surrounding environment.

[0039] Preferably, the protective cover 2 is made of steel plate to ensure the overall strength of the protective cover 2.

[0040] Among them, the protective cover 2 is circular, that is, Figure 5 In the shape shown, the protective cover 2 can prevent oil from dripping onto the end of the support roller 1, preventing oil from splashing around when the support roller 1 rotates at high speed. Furthermore, if oil is already present on the end of the support roller 1, the protective cover 2 can confine the oil to the area blocked by the protective cover 2, thereby reducing the probability of surrounding equipment being corroded by the oil and also reducing pollution to the surrounding environment.

[0041] Specifically, the diameter of the protective cover 2 is 600 mm and the width is 150 mm, which ensures the protective effect of the protective cover 2 on the end of the support roller 1.

[0042] In addition, a notch is provided on the protective cover 2 , and the central angle of the notch is 60°, which facilitates the installation of the protective cover 2 .

[0043] See also Figures 1 to 8 The protective cover 2 is provided with a mounting hole 201, and the fixing member 102 is engaged in the mounting hole 201. By engaging the fixing member 102 in the mounting hole 201, the protective cover 2 can be installed, which is convenient for operation and also convenient for subsequent removal of the protective cover 2.

[0044] Among them, a pair of oil collecting mechanisms are installed on the protective cover 2 to collect oil stains on the outer surface of the protective cover 2, so that the oil stains are not easy to drip onto the ground, thereby ensuring the cleanliness of the ground.

[0045] See also Figures 1 to 8 A pair of oil collecting mechanisms are symmetrical about the notch, and the oil collecting mechanism includes a horizontal plate 202, which is fixedly connected to the mounting hole 201. The horizontal plate 202 is used to install an oil collecting box 206, and the oil collecting box 206 is used to collect oil stains on the outer surface of the protective cover 2.

[0046] Among them, the horizontal plate 202 is carved with a chute 203, and the horizontal plate 202 is provided with an oil collecting box 206 on one side. The oil collecting box 206 is connected to a slide plate, which slides in the chute 203. The oil collecting box 206 is fixed on the horizontal plate 202 by the mutual cooperation between the slide plate and the chute 203.

[0047] In addition, a latch 204 is slidably provided on the horizontal plate 202, and one end of the latch 204 passes through the slide slot 203. The latch 204 is used to fix the oil collecting box 206 so that the oil collecting box 206 is not easy to separate from the horizontal plate 202.

[0048] Specifically, the outer wall of the protective cover 2 is provided with a pair of cutout grooves 205, each corresponding to a pair of oil collecting boxes 206. One right-angled side of the oil collecting box 206 engages within the cutout grooves 205. The cutout grooves 205 are provided to better secure the oil collecting box 206. At the same time, oil stains on the outer surface of the protective cover 2 are blocked by the oil collecting box 206 and collected within the oil collecting box 206.

[0049] In addition, the inner edge of the oil collecting tank 206 close to the slide plate is provided with a chamfer 2061, so that the oil stains on the outer surface of the protective cover 2 can better enter the oil collecting tank 206 for collection.

[0050] When in use, the protective cover 2 is mounted on the outer side of the end of the support roller 1, that is, the fixing member 102 is inserted into the mounting hole 201 to fix the protective cover 2. At the same time, a pair of oil collecting tanks 206 are respectively mounted on a pair of horizontal plates 202.

[0051] When oil drips from the upper side of the protective cover 2, the oil will drip onto the outer surface of the protective cover 2 instead of the end of the support roller 1, thereby blocking the oil and preventing the oil from splashing around when the support roller 1 rotates at high speed.

[0052] The oil on the outside of the protective cover 2 will flow along the protective cover 2 and will be collected in the oil collecting box 206, so that the oil is not easy to drip onto the ground, thereby ensuring the clean effect of the ground.

[0053] If there is oil on the end of the support roller 1, the protective cover 2 can be used to limit the oil to the range blocked by the protective cover 2, thereby reducing the probability of surrounding equipment being corroded by the oil and also reducing pollution to the surrounding environment.

[0054] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
