Description

Technical Field

[0001] This utility model relates to the field of ring rolling mill technology, and in particular to a main roll drive system for an axial radial ring rolling mill. Background Technology

[0002] Ring rolling mills, also known as hole expanders, are classified into vertical and horizontal types based on the form of the frame and the position of the ring-shaped parts. Most small and medium-sized ring rolling mills adopt an inclined vertical design for ease of operation, while large ring rolling mills are mostly horizontal for convenient horizontal movement and transmission.

[0003] The special forging equipment for producing bearing rings, which is widely used in the bearing industry, is used to roll and expand the ring blanks forged in the previous blanking process into shape.

[0004] In existing technology, such as the horizontal ring rolling mill disclosed in Chinese announcement number CN218744617U, a worktable, a retractable roller, and a limiting roller are included. A rotatable retractable roller is located in the middle of the left side of the worktable, and this roller is fixed to the far left of the worktable by an inverted "L"-shaped metal support plate. A limiting roller is fixed in the middle of the worktable, located to the right of the retractable roller. This invention achieves the effect of allowing the horizontal ring rolling mill to automatically transport the ring after it has been expanded and cooled without the need for clamping by other tools, through the cooperation of the retractable roller, rollers, limiting roller, torsion spring, mounting block, and first sliding plate for hole enlargement; the cooperation of spray pipe, connecting sleeve, and valve for cooling; and the cooperation of second guide rod, third sliding plate, top plate, and conveyor belt for conveying.

[0005] The above-mentioned technology has achieved the effect of allowing multiple people to use it simultaneously, but there are still some shortcomings, specifically:

[0006] Traditional roll drive systems often adopt an integral rigid structure, lacking modular partition design, which leads to uneven stress transmission between components, easily causing vibration and deformation that affects processing accuracy. Limiting devices mostly rely on fixed guide rails or mechanical stops, making it difficult to achieve dynamic compensation, and positioning deviations are prone to occur when thermal expansion or load changes. Utility Model Content

The limiting mechanism, through the cooperation of the cylinder-driven swing bracket and the limiting groove, forms a dynamic limiting compensation mechanism, which effectively controls the axial displacement of the roll. The rotating roll mechanism integrates a motor drive and transmission rod linkage system, which realizes the rapid positioning and fine adjustment of the transmission rod through the slot and thread adjustment device. The limiting roll mechanism adopts an auxiliary arm structure driven by an electric telescopic rod, combined with a sliding transmission rod design, which enables the limiting roll to have multi-dimensional adjustment capabilities and improves the convenience of equipment maintenance, thereby solving the problems mentioned in the background technology.

[0033] Example 2: As Figure 1 , Figure 5 , Figure 6 As shown, the inner wall of the auxiliary arm 416 is provided with a slot B14, a card plate 15 is fixedly installed on the surface of the transmission rod B403, a threaded rod B16 is fixedly installed at the top of the transmission rod B403, and a throttle B17 is provided on the surface of the threaded rod B16.

[0034] In this embodiment, efficient assembly and precise adjustment of the limiting roller mechanism 4 are achieved. The sliding connection between the clamping plate 15 and the clamping groove B14 can compensate for manufacturing errors and improve assembly adaptability. The threaded rod B16 driven by the throttle B17 can quickly achieve axial locking of the transmission rod B403. Compared with the traditional bolt fixing method, the adjustment efficiency is improved and the anti-loosening reliability is enhanced. The limiting design of the clamping groove B14 enables the auxiliary arm 416 to have an adjustable range, effectively avoiding stress concentration problems. This structure shortens the maintenance time of the limiting roller mechanism 4 and improves the smoothness of movement. It is particularly suitable for high-frequency vibration conditions and significantly reduces the risk of equipment downtime.

[0035] The working principle of this embodiment is as follows: During use, the main roller mechanism 1, limiting mechanism 2, rotating roller mechanism 3, and limiting roller mechanism 4 are first assembled. Mounting block A101, base plate A102, and top plate A103 fix the main roller mechanism 1 to the equipment. Mounting block B201, base plate B202, and top plate B203 fix the limiting mechanism 2 to the equipment. Mounting block C301, base plate C302, and top plate C303 fix the rotating roller mechanism 3 to the equipment. Finally, side plate 401 fixes the limiting roller mechanism 4 to the equipment. During use, the workpiece is first placed on the surface of the main roller body 104. Then, the cylinder 214 at the top of the positioning block 213 is activated, causing the cylinder 214 to drive the fixed ball 216 and rotating rod B217 via the fixing rod 215. Together, they rotate to the right, and at this time, the rotating rod B217 drives the fixed frame 211 to rotate to the right through the rotating groove B212. Then, the fixed frame 211 drives the rotating rod A206 and the bracket 207 to rotate together through the rotating block 210, so that the rotating rod A206 rotates inside the fixed plate 204 through the rotating groove A205, so that the bracket 207 drives the top cover 208 to rotate upward. At this time, the top cover 208 rotates upward on the surface of the main roller body 104 through the limiting groove 209. Then, the motor 305 is started, so that the transmission rod A306 rotates at the top of the top plate C303 through the transmission groove A304, so that the roller body 307 rotates at the top of the top plate C303. Finally, the electric extension at the bottom of the bottom plate B202 is started. The telescopic rod 415 causes the electric telescopic rod 415 to slide the connecting plate 412 to the left. At this time, the rotating block B410 rotates inside the connecting plate 412 through the connecting groove B413, and the protrusion B411 rotates inside the connecting plate 412 through the rotating groove B414. Then, the rotating block B410 drives the rotating block A407 to rotate to the left through the connecting rod 409, and the rotating block A407 rotates inside the bottom block 404 through the connecting groove A405. This causes the protrusion A408 to rotate inside the bottom block 404 through the rotating groove A406, and the bottom block 404 drives the transmission rod B403 to rotate inside the side plate 401 through the transmission groove B402, causing the auxiliary arm 416 to drive the limiting roller body 417. Together, they slide towards the workpiece to achieve a limiting effect. When disassembly and maintenance are required after prolonged use, pinch the handle A13 and rotate it, causing it to rotate upwards via the threaded rod A9. Once the handle A13 is completely rotated out of the surface of the threaded rod A9, pinch the baffle 10 and pull it upwards, causing it to slide upwards via the groove 11 on the surface of the threaded rod A9. Simultaneously, the baffle 10 slides upwards via the positioning groove B12 on the surface of the limiting block 8. Finally, pinch the roller body 307 and rotate it upwards, causing it to slide upwards via the slot A5 and positioning groove A6 on the surfaces of the transmission rod A306 and the limiting plate 7, achieving the disassembly and maintenance effect. Then, pinch the handle B17 and rotate it.Rotate the throttle B17 upwards on the surface of the threaded rod B16 until it is completely rotated out of the surface of the threaded rod B16. Then, pinch the auxiliary arm 416 and pull it upwards, causing the auxiliary arm 416 to slide upwards on the surface of the transmission rod B403 through the mounting groove 418. The auxiliary arm 416 also slides upwards on the surface of the clamping plate 15 through the clamping groove B14 for disassembly and maintenance.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
