Description

Technical Field

[0001] This utility model relates to the field of bearing ring processing technology, and specifically discloses a vertical bearing ring rolling mill. Background Technology

[0002] Bearing rings are an important component of rolling bearings. They are ring-shaped parts that typically account for 60% to 70% of the total bearing weight, and the quality of the ring blank significantly impacts the bearing's performance and service life. The primary function of bearing rings is to bear all the bearing loads. The inner ring usually mates with the shaft, while the outer ring mates with the bearing housing. Bearing ring manufacturing mainly involves two parts: initial forging and subsequent forming. The subsequent forming is primarily achieved using a ring rolling mill. The ring rolling mill processes the forged bearing rings through plastic deformation, reducing the wall thickness, increasing the diameter, and shaping the cross-sectional profile to achieve the required shape and dimensions.

[0003] The ring rolling mill is equipped with a driving wheel and a driven wheel. The driving wheel rotates the bearing ring, providing rotational power; the driven wheel applies pressure to the surface of the bearing ring, controlling its deformation and stretching it to the required size. Currently, most ring rolling mills are horizontal structures, with processing areas on both sides, occupying a large area and requiring significant processing space. Furthermore, because the bearing rings are arranged flat, a large force needs to be applied to the driven wheel to stretch the bearing rings in order to ensure the forming rate. Therefore, the existing ring rolling mills described above have high energy consumption, and long-term high energy consumption will significantly increase the operating costs of production enterprises, adding to their economic burden. Utility Model Content

[0004] To address the issues of large space requirements and high energy consumption in current bearing ring rolling mills, this invention provides a vertical bearing ring rolling mill.

Therefore, this invention has a very broad application prospect. Attached Figure Description

A first conical roller 3 is rotatably installed inside the first conical roller platform 2. The tip of the first conical roller 3 is arranged obliquely upward, and its right conical surface is perpendicular to the ground. A first motor 13 is fixedly installed at the bottom of the first conical roller platform 2. The output shaft of the first motor 13 is connected to the first conical roller 3, thereby driving the first conical roller 3 to rotate in the first conical roller platform 2.

[0025] A second conical roller platform 4 is provided on the side of the first conical roller platform 2, and a receiving frame 16 is fastened to the right side of the second conical roller platform 4. A first cylinder 15 is fixedly installed inside the support frame 1, and the piston rod of the first cylinder 15 is arranged laterally and faces the second conical roller platform 4. A vertical rod is fixedly installed inside the receiving frame 16, and the vertical rod is fastened to the end of the piston rod of the first cylinder 15, so that the first cylinder 15 drives the second conical roller platform 4 to move laterally inside the support frame 1. A second conical roller 5 is rotatably installed inside the second conical roller platform 4, and the second conical roller 5 is symmetrically arranged with the first conical roller 3. A second motor 14 is fixedly installed at the bottom of the second conical roller platform 4, and the output shaft of the second motor 14 is connected to the second conical roller 5, so that the second motor 14 drives the second conical roller 5 to rotate inside the second conical roller platform 4.

[0026] A vertical plate 6 is fixedly installed on the side of the support frame 1. A horizontal beam 7 is fixedly installed on the side plate surface of the vertical plate 6. A first guide rail 17 and a second guide rail 18 are symmetrically installed at the bottom of the horizontal beam 7. A first support arm 8 and a second support arm 9 are slidably installed on the first guide rail 17 and the second guide rail 18, respectively. The inner end of the first support arm 8 and the second support arm 9 is slidably engaged with the first guide rail 17 and the second guide rail 18, respectively. A horizontal plate 19 is fixedly inserted into the outer end of the first support arm 8 and the second support arm 9. A plurality of linearly arranged adjustment holes 21 are provided on the horizontal plate 19. Locking bolts 22 are provided in the adjustment holes 21. The locking bolts 22 are used to fasten the horizontal plate 19 to the first support arm 8 and the second support arm 9. By setting the cooperation structure between the horizontal plate 19 and the adjustment holes 21, the installation position of the horizontal plate 19 can be flexibly adjusted, enhancing the flexibility of this utility model.

[0027] Ball seats 20 are fastened to the inner sides of the two horizontal plates 19. A sliding ball 10 is rolled inside the ball seat 20. The sliding ball 10 can contact the outer wall of the bearing ring, so that the sliding ball 10 slides with the bearing ring.

[0028] A fixing seat 23 is fastened to the side plate surface of the vertical plate 6. The fixing seat 23 is arranged above the crossbeam 7. A second cylinder 24 is fixedly installed inside the fixing seat 23. The cylinder body of the second cylinder 24 is fastened to the fixing seat 23.

The bottom of the connecting plate 25 is fastened to the base 11, thereby driving the base 11 to move vertically by the second cylinder 24.

[0029] The fixed base 23 has a vertical beam 27 fixedly installed inside. The inner side of the vertical beam 27 is fastened to the vertical plate 6. Both the connecting plate 25 and the base 11 are provided with through grooves to facilitate the passage of the vertical beam 27, so that the inner wall of the through groove slides with the vertical beam 27.

The bottom end of the sliding rod 28 is fastened to the connecting plate 25, and the top end of the sliding rod 28 is fixedly fitted with a limit ring 29. By setting the vertical beam 27 and the sliding rod 28, the stability of the second cylinder 24 when lifting the base 11 is increased, and the limit ring 29 can prevent the sliding rod 28 from falling out of the fixed base 23.

[0030] A turntable 26 is fixedly mounted on the outer side of the base 11. A rotating shaft is rotatably mounted inside the turntable 26. This drive shaft is connected to the rotating roller 12, thereby driving the rotating roller 12 to rotate via the turntable 26. The rotating roller 12 has a symmetrical stepped structure. The diameter of the middle part of the rotating roller 12 is smaller than the diameter of the two ends, which facilitates the support of the bearing rings, allowing the bearing rings to stand upright on the rotating roller 12 and ensuring that the bearing rings do not fall off the rotating roller 12.

[0031] The working principle of this utility model is as follows: The operator can place the forged bearing ring on the rotating roller 12, and by adjusting the first support arm 8 and the second support arm 9, make the sliding balls 10 on both sides of the rotating roller 12 contact the outer wall of the bearing ring; the first conical roller 3 and the second conical roller 5 can clamp the two ends of the bottom of the bearing ring. At the same time, the first motor 13, the second motor 14, and the second cylinder 24 are started, causing the base 11 to raise the arrangement height of the rotating roller 12, and in conjunction with the rotation of the first conical roller 3 and the second conical roller 5, the bearing ring is vertically stretched to the required size.

[0032] In addition, operators can adjust the distance between the first conical roller 3 and the second conical roller 5 by activating the first cylinder 15, thereby adapting to bearing rings of various thicknesses.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
