Main rolling core roller system, ring rolling mill and ring rolling mill radial main rolling core roller angle adjusting method

Abstract

The invention discloses a main rolling core roller system, a ring rolling mill and a ring rolling mill radial main rolling core roller angle adjusting method, and belongs to the field of metal rolling. The main rolling core roller system comprises a main rolling core roller, a bearing pedestal guide device and a main rolling core roller moving device, wherein one end of the main rolling core roller is connected with a first main rolling core roller sliding block through a first bearing portion, and the other end of the main rolling core roller is connected with a second main rolling core roller sliding block through a second bearing portion; the bearing pedestal guide device is connected with the first main rolling core roller sliding block and the second main rolling core roller sliding block respectively, and the bearing pedestal guide device is used for guiding inclination of the main rolling core roller and bearing radial force and axial force at two ends of the main rolling core roller; and the main rolling core roller moving device comprises a first independent driving end and a second independent driving end, the first independent driving end is connected with the first mainrolling core roller sliding block, and the second independent driving end is connected with the second main rolling core roller sliding block. According to the main rolling core roller system, the ring rolling mill and the ring rolling mill radial main rolling core roller angle adjusting method, the subsequent machining amount of large special-shaped ring pieces is reduced.

Description

technical field [0001] The invention belongs to the field of metal rolling, and in particular relates to a main mandrel roll system, a ring rolling machine and a method for adjusting the angle of the radial main mandrel roll of the ring rolling machine. Background technique [0002] In the radial and axial rolling process of large ring forgings, the radial rolling is completed by the main core roll, which makes the diameter of the ring forging larger, and the rolling in the height direction of the ring is completed by the upper and lower axial core rolls to control the radial main roll. The speed of rolling core roll, axial upper and lower rolling core roll and holding roll can get the required ring forging. [0003] In the process of implementing the embodiments of the present invention, the inventors found at least the following defects in the background technology: [0004] When rolling special-shaped ring forgings, because the upper and lower forces of the main roll are...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a main mandrel roll system, a ring rolling machine and a method for adjusting the radial main mandrel roll angle of the ring rolling machine. Not the same, when rolling with a conventional ring rolling machine, it often occurs that the special-shaped ring forgings do not meet the design standards, and the ring forgings need more follow-up processing in the later stage, which is time-consuming and labor-intensive.
