Description

Technical Field

[0001] This utility model belongs to the field of guide roller technology, and in particular relates to a guide roller assembly for steel rolling. Background Technology

[0002] Guide rolls are an indispensable and important component in section steel rolling mills. In order to ensure that the rolled workpieces enter and exit the roll pass accurately in the specified position, direction and required state, to avoid the workpieces getting tangled in the rolls, being scraped and squeezed, and to ensure the safety of workers and equipment, guide rolls must be installed at the front and rear of the section steel rolling mill.

[0003] Currently, existing guide rollers are all fixed structures, and the rolling stock will transmit a lot of high temperature when passing through them. Under the influence of high temperature, the guide rollers are severely worn and easily damaged. Moreover, the maintenance method of replacing the whole roller will increase the cost.

[0004] To address the aforementioned issues, this application proposes a guide roller assembly for steel rolling. Utility Model Content

[0005] The purpose of this invention is to provide a guide roller assembly for steel rolling, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a guide roller assembly for steel rolling, including a support and an inner roller;

[0008] The outer roller, located on the outermost layer of the inner roller, is a vulnerable part that directly contacts the workpiece and is subjected to high temperatures and wear. It can be installed, disassembled, and replaced independently. The upper end of the inner roller is provided with a connecting plate for assembling the inner roller and the outer roller into one unit.

[0009] The heat dissipation layer, located between the inner and outer rollers, is used to cool the outer rollers in real time. The heat dissipation layer has a spiral tube inside that transmits the cooling medium in real time. The upper end of the connecting plate is provided with an annular frame, through which the cooling medium is injected via the drain pipe at the upper end.

[0010] Furthermore, the heat dissipation layer has flow interception channels at both the upper and lower ends, and an upward-facing hole at one end, which is coaxial with the drainage pipe.

[0011] Furthermore, the upper end of the connecting plate is provided with a storage cavity for storing cooling medium, which is connected to the drainage pipe.

[0012] Furthermore, the upper end of the heat dissipation layer is provided with a double-layer conduit that connects to the lower end hole of the connecting plate, which is used to connect the interception channel to the storage cavity.

[0013] Furthermore, the lower end of the annular frame is rotatably connected to the storage cavity, and a sealing block is provided on the outside to abut against the inside of the storage cavity to form a seal, so that the annular frame and the drain pipe are not affected by the rotational movement of the inner roller.

[0014] Furthermore, both the upper and lower ends of the outer roller are provided with protruding rings to fit the connecting plate inside.

[0015] Furthermore, the double-layer conduit is also used to replace bolts to connect and fix the heat dissipation layer to the frame plate.

[0016] Furthermore, the outer side of the heat dissipation layer is provided with staggered reinforcing blocks and thermal pads. The reinforcing blocks are used to enhance the support of the outer roller, and the thermal pads are used to absorb the heat of the outer roller.

[0017] This utility model has the following beneficial effects:

[0018] This invention divides the guide roller into three layers: an inner roller, a heat dissipation layer, and an outer roller. During the trial period, a cooling medium is continuously injected into the spiral tube through the diversion pipe, which can cool the outer roller and reduce its impact from high temperature, thereby slowing down the wear of the outer roller. This improves both working stability and overall service life.

[0019] This invention features a hollow outer roller placed on the outermost layer, which can withstand all wear during use and can be directly replaced if damaged. It is simple and convenient to operate, shortens maintenance time, and reduces investment costs, making it more practical overall.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-5 As shown, this utility model is a guide roller assembly for steel rolling, including a support 1 and an inner roller 2;

[0032] The outer roller 3, located on the outermost layer of the inner roller 2, is a vulnerable part that directly contacts the workpiece and is subjected to high temperature and wear. It can be installed, disassembled and replaced separately. The upper end of the inner roller 2 is provided with a connecting plate 4, which is used to assemble the inner roller 2 and the outer roller 3 into one piece.

[0033] The heat dissipation layer 7 is located between the inner roller 2 and the outer roller 3 and is used to cool the outer roller 3 in real time. The heat dissipation layer 7 has a spiral tube 8 inside to transmit the cooling medium in real time. The upper end of the connecting plate 4 is provided with an annular frame 5, through which the cooling medium is injected through the drain pipe 6 at its upper end.

[0034] This embodiment provides a guide roller structure with inner and outer layers. The outer roller 3 is a vulnerable part that can be replaced separately after damage. At the same time, the cooling effect applied to it by the heat dissipation layer 7 can reduce the impact of high temperature, prevent aggravated wear, extend service life and ensure operational stability.

[0035] The heat dissipation layer 7 has interception channels 9 at both the upper and lower ends, and an upward-facing hole at one end, which is coaxial with the drainage pipe 6. When assembled and used, the hole is parallel to the axis of the drainage pipe 6.

[0036] The upper end of the connecting plate 4 is provided with a storage cavity 10 for storing cooling medium, which is connected to the drainage pipe 6 through the holes inside the ring frame 5.

[0037] The upper end of the heat dissipation layer 7 is provided with a double-layer conduit 12 that is connected to the lower end hole of the connecting plate 4. This conduit is used to connect the interception channel 9 to the storage chamber 10. The double-layer conduit 12 is also used to replace bolts to connect and fix the heat dissipation layer 7 to the connecting plate 4.

[0038] The lower end of the ring frame 5 is rotatably connected to the storage cavity 10, and a sealing block 15 is provided on the outside to abut against the inside of the storage cavity 10 to form a seal, so that the ring frame 5 and the drainage pipe 6 are not affected by the rotational movement of the inner roller 2, and the cooling medium injected by the drainage pipe 6 can enter the interior of the storage cavity 10 in real time.

[0039] The outer roller 3 has protruding rings 11 at both the upper and lower ends, which fit the connecting plate 4 inside, maintaining the aesthetic appearance of the external structure while providing a certain degree of protection.

[0040] The heat dissipation layer 7 has staggered reinforcing blocks 13 and heat-conducting pads 14 on its outer side. The reinforcing blocks 13 are used to enhance the support of the outer roller 3, and the heat-conducting pads 14 are used to absorb the heat of the outer roller 3.

[0041] It is understandable that this utility model can cool the outer roller 7 of the outer layer through the heat dissipation layer 7 of the middle layer, so as to reduce the degree of impact of high temperature and slow down the wear of the rolling parts. At the same time, the easily damaged outer roller 7 can be replaced separately through the inner and outer layering method, which facilitates maintenance and replacement while reducing cost investment.

[0042] A specific application of the operation process in this embodiment is as follows: First, the guide roller is divided into three layers: inner, middle, and outer. From the inside out, they are a solid inner roller 2, a heat dissipation layer 7, and an outer roller 3 that contacts the workpiece. During use, the outer roller 3 bears the wear and high temperature. When damaged, the inner roller 2, heat dissipation layer 7, and outer roller 3 can be disassembled by removing the connecting plate 4. The outer roller 3 can be replaced directly to restore normal use, reducing costs and making maintenance simpler and more efficient. In addition, during use, the multi-layer sealing effect applied by the sealing block 15 allows the connecting plate 4 to still inject the cooling medium into the storage cavity 10 through the diversion pipe 6 when rotating. Then, it is led out to the interception channel 9 through the double-layer conduit 12 and finally flows inside the spiral tube 8 to remove the heat transmitted from the outer roller 3. This allows for real-time cooling of the outer roller 3, reducing its impact from high temperatures and extending its service life.
