Description
Technical Field
[0001] This invention relates to the field of three-roll mill technology, and more particularly to a drive shaft system for a three-roll mill. Background Technology
[0002] The primary function of a three-roll mill is to roll metal materials to change their shape and size. Through the interaction of three rolls, the mill plastically deforms the metal to achieve the desired shape and size. In bar and wire rod rolling, reduction sizing mills can significantly improve the dimensional accuracy and performance stability of products. For example, the use of the KOCKS three-roll reduction sizing mill results in higher dimensional accuracy and more stable performance for round steel products, efficiently meeting the steel demands of high-end automotive parts, bearing steel, and oil extraction industries. Furthermore, reduction sizing mills offer advantages such as high deformation efficiency, small width expansion coefficient, and uniform stress distribution across the rolled section. They can also achieve precise control through intelligent matching of rolling process parameters via a remote control system. Existing three-roll mills are used for bar and wire rod rolling. During rolling, the steel undergoes deformation to achieve the desired shape and size. However, this deformation and stress can cause the steel to wobble upon exiting the mill, leading to deviations, especially when multiple rolling passes are required, which can easily affect the rolling process. Summary of the Invention
[0003] This invention discloses a drive shaft system for a three-roll mill, aiming to solve the technical problem in the prior art where existing three-roll mills are used for rolling bars and wire rods. During the rolling process, the steel undergoes deformation to achieve the required shape and size. However, due to the deformation and stress, the steel will wobble when exiting the mill, causing it to deviate. This is especially problematic when multiple rolling operations are required, as it can easily affect the rolling process.
[0004] The present invention proposes a drive shaft system for a three-roll mill, including a rolling mill housing, an installation frame on one side of the rolling mill housing, and a stable rolling guide module on the installation frame; a guide ring frame on the outer wall of the other side of the rolling mill housing, a rolling cleaning module on one end of the guide ring frame, and a rolling guide module on the guide ring frame.
[0005] The stable rolling guide module includes an elastic curvature plate and two elastic curvature pieces, with both elastic curvature pieces located above the elastic curvature plate.
[0006] The rolling cleaning module includes four cleaning rollers, and each of the four cleaning rollers has a cleaning brush fixedly connected to its outer wall.
[0007] The rolling guide module includes three guide clamps, all of which are located inside the guide ring frame.
[0008] The system comprises a rolling mill housing, a mounting frame, a stabilizing guide module, a guide ring frame, a rolling cleaning module, and a rolling guide module. The stabilizing guide module guides the steel at the rolling output end, preventing it from wobbling due to shape changes during output and thus avoiding steel deviation, meeting the requirements for stable rolling. The rolling cleaning module cleans the surface of the steel before rolling to remove impurities, improving the rolling effect and meeting rolling requirements. The rolling guide module guides and limits the position of the steel before rolling, facilitating rolling and increasing the rolling effect of the device.
[0009] In a preferred embodiment, the stable guide rolling module further includes four fixed end pieces. Four fixing openings are provided on both outer walls of the mounting frame. The four fixed end pieces are respectively fixedly connected to the interior of the four fixing openings. Two of the fixed end pieces have their opposite ends fixedly connected to the outer walls of the elastic curvature plates, and one end of each of the other two fixed forgings is fixedly connected to one outer wall of each of the two elastic curvature plates. Two movable guides are provided on the elastic curvature plates. Arc-shaped guide openings are provided on both outer walls of the mounting frame, and the two movable guides are movably connected to the inner walls of the two arc-shaped guide openings. A servo motor is fixedly connected to one outer wall of the mounting frame. The output shaft of the servo motor is connected to a drive rod via a coupling. Two curvature winding wheels are fixedly connected to the outer wall of the drive rod. Connecting cables are provided on both curvature winding wheels, and connecting rods are provided at one end of each connecting cable. The two connecting rods are respectively located on the two movable guides, and the elastic... Both outer walls of the curved plate are movably connected to connecting U-rods. One end of each connecting U-rod is movably connected to one outer wall of each of the two elastic curved plates. Multiple mounting holes are equally spaced on each of the two elastic curved plates. Mounting shafts are movably connected to the inner walls of the multiple mounting holes. Mounting components are provided on the outer walls of the multiple mounting shafts. The same buffer bracket is fixedly connected to the outer walls of the two mounting components on the same vertical plane. Buffer frames are fixedly connected to the multiple buffer brackets. Four movable openings are provided on the outer walls of the multiple buffer frames. The same resistance plate is provided on the inner walls of the four movable openings on the same buffer frame.

Stabilizing wheels are provided on the multiple connecting frames. Telescopic springs are provided on the top of the multiple resistance plates. The top ends of the multiple telescopic springs are fixedly connected to the top inner walls of the multiple buffer frames.
[0010] By incorporating a stabilizing guide module, the steel at the roll output end can be stably guided, preventing it from wobbling due to shape changes during output. This avoids deviation of the steel after output due to wobbling, thus improving the effectiveness of the device. Furthermore, the stability of the rolls is maintained during multiple roll processes that gradually shape and size the steel, further enhancing the device's performance. During wire output, the elastic curvature plate and elastic curvature sheet can be bent to ensure the wire falls smoothly onto the collection table, preventing wobbling and wire scattering, thereby increasing the device's versatility.
[0011] In a preferred embodiment, the rolling guide module further includes three mounting brackets, each fixedly connected to one outer wall of the guide ring frame. Each of the three mounting brackets has an electric telescopic rod fixedly connected to one outer wall. The output ends of the three electric telescopic rods are fixedly connected to connecting plates. The outer wall of the guide ring frame has three mounting openings. The inner walls of each of the three mounting openings are movably connected to movable bases. One outer wall of each of the three movable bases is fixedly connected to a connecting cable. One end of each connecting cable is fixedly connected to one outer wall of one of the three connecting plates. The inner walls of each of the three mounting openings are fixedly connected to fixed bases. Each fixed base has a limiting component fixedly connected to it, and each limiting component has a limiting hole. The three connecting cables pass through the three limiting holes. The movable bases and fixed bases within the same mounting opening have the same telescopic spring rod on their opposite outer walls. Each of the three movable bases and three fixed bases has a linkage rod. One end of each linkage rod is connected to a mounting base. The multiple mounting bases are fixedly connected to three guide clamps.
[0012] By incorporating a rolling guide module, the rolling guide module can guide and limit the position of the steel before rolling to facilitate the rolling process, thereby increasing the effectiveness of the device. Furthermore, during the guiding process, the device can be adjusted according to the size of the steel to clamp and guide steel of different sizes, thus increasing the applicability of the device and further improving its effectiveness.
[0013] In a preferred embodiment, the rolling cleaning module further includes a mounting ring frame, which is fixedly connected to the outer wall of the guide ring frame. A general-purpose motor is fixedly connected to the mounting ring frame, and the output shaft of the general-purpose motor is connected to a transmission wheel via a coupling. A gear ring is movably connected to the mounting ring frame. The outer wall of the gear ring has a groove, and the inner wall of the groove and the outer wall of the transmission wheel are provided with the same transmission belt. Four fixed support plates are fixedly connected at equal intervals to the inner wall of the mounting ring frame. Two shaft members are movably connected to each of the four fixed support plates. The outer walls of the multiple shaft members are fixedly connected with linkage wheels. The outer walls of every two adjacent linkage wheels are provided with the same linkage belt. The outer walls of the four shaft members are fixedly connected with driven gears, and the four driven gears mesh with the gear ring. The four cleaning rollers are respectively fixedly connected to the outer walls of the other four shaft members.
[0014] By incorporating a rolling cleaning module, the steel surface can be cleaned before rolling to remove dust or impurities, thus preventing dust or impurities from affecting the rolling quality and increasing the effectiveness of the device. Furthermore, the device can thoroughly clean the steel surface, avoiding any omissions and further enhancing the cleaning effect to improve the subsequent rolling quality.
[0015] In a preferred embodiment, the rolling mill box is provided with a radial adjustment component and three eccentric sleeves. Each of the three eccentric sleeves is provided with two toothed handles. A first flange and a second flange are provided inside each of the three eccentric sleeves. A tie rod is provided inside the first flange and the second flange located inside the same eccentric sleeve. A conveyor drive shaft is provided at one end of each of the three tie rods. An axial adjustment component is provided inside each of the three eccentric sleeves. The three axial adjustment components are located outside the first flange. Rolling rings are provided on the outer walls of each of the three tie rods. The three rolling rings are located between the three first flanges and the three second flanges, respectively.
[0016] The device is equipped with an eccentric sleeve, a toothed joint, a first flange, a second flange, a tie rod, a conveyor drive shaft, an axial adjustment component, a rolling ring, and a radial adjustment component. During use, the conveyor drive shaft can drive the tie rod and the rolling ring to facilitate the rolling operation of steel. At the same time, the first flange and the second flange can cooperate with the tie rod to separate from the rolling ring for replacement of the rolling ring.
[0017] As can be seen from the above, the drive shaft system for a three-roll mill provided by the present invention has the effect of increasing the stability of the rolling operation.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0030] The transmission shaft system for a three-roll mill disclosed in this invention is mainly used in rolling processes where steel will sway due to deformation and stress during discharge, which can lead to steel deviation, especially in scenarios where multiple rolling operations are required, which can easily affect the rolling process.
[0031] Reference Figures 1-10 A drive shaft system for a three-roll mill includes a roll box 1, a mounting frame 3 on one side of the roll box 1, and a stable rolling guide module 2 on the mounting frame 3. A guide ring frame 6 is provided on the outer wall of the other side of the roll box 1, a rolling cleaning module 5 is provided at one end of the guide ring frame 6, and a roll guiding module 7 is provided on the guide ring frame 6.
[0032] The stable rolling guide module 2 includes an elastic curvature plate 203 and two elastic curvature pieces 204, with both elastic curvature pieces 204 located above the elastic curvature plate 203.
[0033] The rolling cleaning module 5 includes four cleaning rollers 502, and each of the four cleaning rollers 502 has a cleaning brush 504 fixedly connected to its outer wall.
[0034] The rolling guide module 7 includes three guide clamps 709, and all three guide clamps 709 are located inside the guide ring frame 6.
[0035] Specifically, the stabilizing guide module 2 can stably guide the steel at the output end of the roll during use, preventing it from shaking due to shape changes during output, and thus preventing the steel from deviating, thereby meeting the requirements for stable rolling; the rolling cleaning module 5 can clean the surface of the steel before rolling to remove impurities adhering to its surface, thereby increasing the rolling effect and meeting the rolling requirements; the rolling guide module 7 can guide the steel before rolling and limit its position to facilitate rolling and increase the rolling effect of the device.
[0036] Reference Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7In a preferred embodiment, the stabilizing guide rolling module 2 further includes four fixed end pieces 211. Four fixing openings are provided on both outer walls of the mounting frame 3. The four fixed end pieces 211 are respectively fixedly connected to the interior of the four fixing openings. Two of the fixed end pieces 211 have their opposite ends fixedly connected to the outer walls of both sides of the elastic curvature plate 203, and one end of the other two fixed forgings is fixedly connected to one side of the outer wall of two elastic curvature plates 204. Two movable guides 207 are provided on the elastic curvature plate 203, and arc-shaped guide openings are provided on both outer walls of the mounting frame 3. 205, two movable guides 207 are respectively movably connected to the inner walls of the two arc-shaped guide openings 205; a servo motor 201 is fixedly connected to one outer wall of the mounting frame 3, the output shaft of the servo motor 201 is connected to a drive rod 210 through a coupling, two curved rollers 202 are fixedly connected to the outer wall of the drive rod 210, each of the two curved rollers 202 is provided with a connecting cable 209, one end of each of the two connecting cables 209 is provided with a connecting rod 208, the two connecting rods 208 are respectively set on the two movable guides 207, and the elastic curved plate 203 Both outer walls are movably connected to connecting U-shaped rods 206. One end of each connecting U-shaped rod 206 is movably connected to one outer wall of each of the two elastic curved plates 204. Multiple mounting holes are equally spaced on each of the two elastic curved plates 204. Mounting shafts 212 are movably connected to the inner walls of each mounting hole. Mounting members 214 are provided on the outer walls of each mounting shaft 212. Two mounting members 214 on the same vertical plane are fixedly connected to the same buffer bracket 215 on opposite outer walls. Buffer frames 221 are fixedly connected to each buffer bracket 215. The outer wall of the buffer sleeve 221 is provided with four movable openings 220. The inner wall of the four movable openings 220 on the same buffer sleeve 221 is provided with the same resistance plate 217. The bottom of the multiple resistance plates 217 is fixedly connected to the connecting rod 218. The bottom end of the multiple connecting rod 218 is fixedly connected to the connecting frame 219. The multiple connecting frames 219 are provided with the stabilizing wheel 213. The top of the multiple resistance plates 217 is provided with the telescopic spring 216. The top of the multiple telescopic spring 216 is fixedly connected to the top inner wall of the multiple buffer sleeves 221 respectively.
[0037] Specifically, during the steel roll output, the steel moves onto the elastic curvature plate 203 and contacts the stabilizing wheel 213 above it. As the steel is output, the resulting swaying is transmitted to the stabilizing wheel 213, and then through it to the connecting frame 219, and further to the connecting rod 218 and the resistance plate 217, causing the telescopic spring 216 to compress. The telescopic spring 216 then returns to its original position. At this time, the resistance plate 217 moves on the buffer sleeve 221. Because the resistance plate 217 and the outer wall of the buffer sleeve 221 have a certain resistance, they will reduce the swaying. Force is consumed to stabilize the output of steel. When the wire rod is finished being rolled and output, the device starts the servo motor 201. The servo motor 201 drives the drive rod 210 and the curvature winding wheel 202 to rotate, thereby winding the connecting cable 209. This causes the connecting cable 209 to pull the connecting rod 208 and the movable guide 207 to move inside the arc-shaped guide 205, thereby causing the elastic curvature plate 203 to change curvature. This, in turn, causes the elastic curvature sheet 204 to change curvature through the connecting U rod 206, so that the wire rod is stably guided and then stably transported to the receiving table.
[0038] In specific application scenarios, the stabilizing guide module 2 is suitable for the steel rolling output stage. That is, the stabilizing guide module 2 can stably guide the steel at the output end of the roll, preventing it from shaking due to shape changes during output, and thus preventing the steel from deviating due to shaking after output, thereby increasing the effectiveness of the device. At the same time, it can also ensure the stability of the roll during multiple rolls of steel with gradually changing shape and size, further increasing the effectiveness of the device. Moreover, when outputting wire, the elastic curvature plate 203 and elastic curvature sheet 204 can be bent to allow the wire to fall smoothly onto the receiving table, avoiding shaking that would cause the wire to scatter, thereby increasing the versatility of the device.
[0039] Reference Figure 2 , Figure 8 and Figure 9In a preferred embodiment, the roll guiding module 7 further includes three mounting brackets 701, each fixedly connected to one outer wall of the guide ring frame 6. Each outer wall of the three mounting brackets 701 is fixedly connected to an electric telescopic rod 702, and the output end of each electric telescopic rod 702 is fixedly connected to a connecting piece 706. The outer wall of the guide ring frame 6 has three mounting openings, the inner walls of each of the three mounting openings are movably connected to a movable base 711, and one outer wall of each of the three movable bases 711 is fixedly connected to a connecting cable 707. One end of each connecting cable 707 is fixed to one outer wall of one connecting piece 706. Connection: The inner walls of the three mounting ports are fixedly connected to fixed bases 704, and the three fixed bases 704 are fixedly connected to limiting components 705. The three limiting components 705 are provided with limiting holes. The three connecting cables 707 pass through the three limiting holes respectively. The movable base 711 inside the same mounting port and the outer wall opposite to the fixed base 704 are provided with the same telescopic spring rod 703. The three movable bases 711 and the three fixed bases 704 are provided with linkage rods 708. One end of the multiple linkage rods 708 is provided with mounting bases 710. The multiple mounting bases 710 are fixedly connected to the three guide plates 709 respectively.
[0040] Specifically, during the rolling input, the steel is located inside the guide ring frame 6. At this time, the electric telescopic rod 702 is activated, which drives the connecting piece 706 and the connecting cable 707 to move. This causes the connecting cable 707 to pull the movable base 711, causing the movable base 711 to move towards the fixed base 704 and compressing the telescopic spring rod 703. Simultaneously, as the movable base 711 moves, the linkage rod 708 on the movable base 711 and the fixed base 704 will move accordingly, causing the linkage rod 708 to drive the three guide clamps 709 to contact the surface of the steel to clamp and guide steel of different sizes.
[0041] In specific application scenarios, the rolling guide module 7 is suitable for the steel guiding and conveying process. That is, when the rolling guide module 7 is used, it can guide the steel before rolling and limit its position to facilitate rolling, thereby increasing the effectiveness of the device. Moreover, when guiding, the device can be adjusted according to the size of the steel to clamp and guide steel of different sizes, thereby increasing the applicability of the device and further improving the effectiveness of the device.
[0042] Reference Figure 1 , Figure 2 , Figure 8 and Figure 10In a preferred embodiment, the rolling cleaning module 5 further includes a mounting ring frame 501, which is fixedly connected to the outer wall of the guide ring frame 6. A general-purpose motor 506 is fixedly connected to the mounting ring frame 501. The output shaft of the general-purpose motor 506 is connected to a transmission wheel 507 via a coupling. A gear ring 509 is movably connected to the mounting ring frame 501. The outer wall of the gear ring 509 has a groove, and the inner wall of the groove and the outer wall of the transmission wheel 507 are provided with the same transmission belt 508. The inner wall of the mounting ring frame 501 is also provided with the same transmission belt 508. Four fixed support plates 503 are fixedly connected at equal intervals. Two shaft members 512 are movably connected to each of the four fixed support plates 503. Linkage wheels 505 are fixedly connected to the outer walls of the multiple shaft members 512. The same linkage belt 511 is provided on the outer walls of every two adjacent linkage wheels 505. Driven gears 510 are fixedly connected to the outer walls of the four shaft members 512. The four driven gears 510 mesh with the gear ring 509. The four cleaning rollers 502 are respectively fixedly connected to the outer walls of the other four shaft members 512.
[0043] Specifically, during the steel rolling process, the steel passes through the mounting ring 501. At this time, the general-purpose motor 506 is started, which drives the transmission wheel 507 to rotate. In conjunction with the transmission belt 508, the gear ring 509 rotates. Since the gear ring 509 meshes with the driven gear 510, the general-purpose motor 506 drives the transmission gear to rotate, which in turn drives the driven gear 510 to rotate the shaft 512. Furthermore, in conjunction with the linkage wheel 505 and the linkage belt 511, the shaft 512 rotates, causing the shaft 512 to drive the cleaning roller 502 and the cleaning brush 504 to rotate, thereby cleaning the surface of the steel.
[0044] In specific application scenarios, the rolling cleaning module 5 is suitable for the steel cleaning process. That is, the rolling cleaning module 5 can clean the surface of the steel before rolling to remove dust or impurities adhering to the steel surface, thereby avoiding the impact of surface dust or impurities on the rolling quality during rolling, thus increasing the effectiveness of the device. Moreover, the device can thoroughly clean the surface of the steel during cleaning to avoid omissions, thereby further increasing the cleaning effect of the device and improving the subsequent rolling quality.
[0045] Reference Figure 1 and Figure 3In a preferred embodiment, the rolling mill box 1 is provided with a radial adjustment component 4 and three eccentric sleeves 14. Each of the three eccentric sleeves 14 is provided with two toothed handles 15. Each of the three eccentric sleeves 14 is provided with a first flange 11 and a second flange 12. Each of the first flanges 11 and the second flanges 12 located inside the same eccentric sleeve 14 is provided with a tie rod 10. One end of each of the three tie rods 10 is provided with a conveyor drive shaft 8. Each of the three eccentric sleeves 14 is provided with an axial adjustment component 9. Each of the three axial adjustment components 9 is located outside the first flange 11. Each of the three tie rods 10 is provided with a rolling ring 13 on its outer wall. The three rolling rings 13 are respectively located between the three first flanges 11 and the three second flanges 12.
[0046] Specifically, during use, the transmission shaft 8 can drive the pull rod 10 and the rolling ring 13 to facilitate the rolling operation of steel. At the same time, the first flange 11 and the second flange 12 can cooperate to separate the pull rod 10 from the rolling ring 13 so that the rolling ring 13 can be replaced.
[0047] Working principle: During the steel rolling process, the steel passes through the mounting ring 501. At this time, the general motor 506 is started, which drives the transmission wheel 507 to rotate. In conjunction with the transmission belt 508, the gear ring 509 rotates. Since the gear ring 509 meshes with the driven gear 510, the general motor 506 drives the transmission gear to rotate, which in turn drives the driven gear 510 to drive the shaft 512 to rotate. This further works with the linkage wheel 505 and the linkage belt 511 to drive the shaft 512 to rotate. As a result, the shaft 512 drives the cleaning roller 502 and the cleaning brush 504 to rotate, thereby cleaning the surface of the steel.
[0048] During the rolling input, the steel is located inside the guide ring frame 6. At this time, the electric telescopic rod 702 is activated, which drives the connecting piece 706 and the connecting cable 707 to move. This causes the connecting cable 707 to pull the movable base 711, making the movable base 711 move towards the fixed base 704 and compressing the telescopic spring rod 703. Simultaneously, as the movable base 711 moves, the linkage rod 708 on the movable base 711 and the fixed base 704 will move accordingly. This causes the linkage rod 708 to drive the three guide clamps 709 to contact the surface of the steel to clamp and guide steel of different sizes.
[0049] When the steel is rolled out, it moves onto the elastic curvature plate 203 and comes into contact with the stabilizing wheel 213 above it. As the steel is rolled out, the resulting sway is transmitted to the stabilizing wheel 213, and then through it to the connecting frame 219, and further to the connecting rod 218 and the resistance plate 217, causing the telescopic spring 216 to compress. The telescopic spring 216 then returns to its original position. At this time, the resistance plate 217 moves on the buffer sleeve 221. Because the resistance plate 217 and the outer wall of the buffer sleeve 221 have a certain resistance, they will mitigate the swaying force. The device consumes energy to stabilize the output of steel. When the wire rod is finished being rolled and output, the device starts the servo motor 201. The servo motor 201 drives the drive rod 210 and the curvature winding wheel 202 to rotate, thereby winding the connecting cable 209. This causes the connecting cable 209 to pull the connecting rod 208 and the movable guide 207 to move inside the arc-shaped guide 205, thereby causing the elastic curvature plate 203 to change curvature. This, in turn, causes the elastic curvature sheet 204 to change curvature through the connecting U rod 206, so that the wire is stably guided and then stably transported to the receiving table.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
