Main mandrel system, ring rolling machine and ring rolling machine radial main mandrel angle adjustment method

Abstract

The invention relates to a main core roll system, a ring rolling machine and a method for adjusting the angle of the radial main core roll of the ring rolling machine, belonging to the field of metal rolling. The main core roll system includes: a main core roll, the main core roll One end of the core roll is connected to the first main core roll slider through the first bearing part, and the other end of the main core roll is connected to the second main core roll slider through the second bearing part; the bearing seat guide device, the bearing The seat guiding device is respectively connected with the first main core roll slider and the second main core roll slider, and the bearing seat guide is used to guide the inclination of the main core roll and carry The radial force and axial force at both ends of the main core roll; the main core roll moving device, the main core roll moving device includes a first independent driving end and a second independent driving end, and the first independent driving end is connected to the The first main core roll slider is connected, and the second independent driving end is connected with the second main core roll slider. It reduces the amount of subsequent processing of large shaped rings.

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.
