Description

Technical Field

[0001] This utility model relates to the field of ring rolling mills, and in particular to a vertical ring rolling mill for processing thick-walled tubes. Background Technology

[0002] A vertical ring rolling mill is a mechanical device used to process ring-shaped parts. It is mainly used in the production of seamless ring parts such as bearings, flat welding flanges, high neck flanges, and small thin-walled cylindrical components. When processing thick-walled tubes, a vertical ring rolling mill is usually used to expand the wall thickness of the tubes.

[0003] A vertical ring rolling mill typically consists of a frame, a bearing roller, a mounting frame, a drive cylinder, an extrusion roller, and a drive mechanism. The extrusion roller is mounted on the front of the mounting frame via the drive mechanism, which in turn drives the mounting frame to move up and down. This allows the mounting frame to move up and down along with the drive mechanism and the extrusion roller, thus enabling the extrusion roller to work in conjunction with the bearing roller to process thick-walled tubes.

[0004] Because the mounting bracket is vertically slidably installed inside the frame via guide columns, and the mounting bracket is driven up and down by a drive cylinder, when the vertical ring rolling mill is not working, the weight of the mounting bracket, drive mechanism, and extrusion roller will act on the drive cylinder, thereby causing the oil inside the drive cylinder to have a certain pressure. Over time, this will affect the service life of the drive cylinder, thus resulting in certain defects. Utility Model Content

The mounting frame 13 is equipped with a servo motor and a reducer to drive the extrusion roller 14 to rotate, thereby driving the extrusion roller 14 to rotate, so that the extrusion roller 14 and the support roller 12 work together.

[0034] In particular, the frame 11 is internally provided with a support assembly 2 for supporting and limiting the mounting bracket 13. The support assembly 2 includes a support plate 21, a slider 24, and a positioning assembly 25. A mounting groove 22 is provided on the side of the frame 11. The support plate 21 is horizontally slidably disposed inside the mounting groove 22. One end of the slider 24 is fixedly connected to the mounting bracket 13.

The support plate 21 is located at the bottom of the slider 24, so that when the support plate 21 and the slider 24 are misaligned... The drive cylinder 15 can drive the mounting frame 13 and the slider 24 to slide up and down inside the frame 11. When the extrusion roller 14 and the bearing roller 12 are not working, the drive cylinder 15 can drive the mounting frame 13 and the slider 24 to slide to the top of the inner cavity of the frame 11, and then slide the support plate 21 to the bottom of the slider 24, so that the support plate 21 supports the slider 24, thereby supporting the mounting frame 13, so that the drive cylinder 15 is not under force when it is not working. One end of the outer wall of the slider 24 is located inside the mounting groove 22, and the positioning component 25 is set at the bottom of the support plate 21.

[0035] Furthermore, the support assembly 2 also includes a support block 26 and a positioning plate 27.
