Large radial-axial ring rolling machine

Abstract

Disclosed is a large radial-axial ring rolling machine. A radial rolling portion is provided with an up-drawing core roller shaft mechanism and a four-post vertical double-acting mechanism, and an axial rolling portion overcomes space limitations and is provided with a lower conical roller driving motor in a forward direction. A slider of the radial rolling portion comprises four guide posts, a fixed frame, a movable frame and the like, all parts are simple in structure, regular in appearance, easy in machining and convenient in assembly, and respective action of vertical support of a core roller is ensured, namely the technical conception of vertical double acting is realized. By the aid of the large radial-axial ring rolling machine, blanks and finished products can horizontally enter and exit the machine, difficulty in feeding and discharging is reduced, a production line can be formed to realize automated feeding and discharging, and the problem of bottleneck in improvement of working efficiency is solved. As the axial rolling portion is provided with the lower conical roller driving motor in the forward direction, assembly difficulty in mounting the high-power motor is greatly reduced, lubricating conditions of a rotating component are greatly improved when the motor works, and the service life of the motor is prolonged. By the aid of the motor mounted in the forward direction, the size of the machine below a horizontal plane of a generatrix on a lower conical roller is reduced, so that the pit depth of a foundation of the portion is decreased.

Description

technical field [0001] The invention relates to a large-scale seamless ring piece hot-rolling forming equipment, that is, a large-scale numerically controlled radial-axial ring rolling machine, specifically a radial rolling part consisting of an upward-drawing core roller mechanism and a four-column type upper and lower double-action mechanism. Composition, the axial rolling section is a large numerically controlled diameter-axial ring rolling machine with the feature of positive installation of the lower tapered roller motor. Background technique [0002] The large-scale numerical control diameter-axial ring rolling machine is a special equipment for hot-rolling large seamless rings, that is, by applying radial and axial rolling forces to the heated blank, the wall thickness is reduced, the diameter is enlarged, and the cross-sectional profile is formed. . See rolling principle figure 1 . [0003] Wind power, aerospace, nuclear power, shipbuilding and other industries re...

AI Technical Summary

Problems solved by technology

It is very difficult to install such a high-power drive motor of the lower tapered roller upside down; the lubrication conditions of the rotating parts of the motor are poor, which is not conducive to the life of the motor

The inverted installation also makes the size of the equipment under the horizontal plane of the upper bus bar of the lower cone roller larger, which increases the depth of the equipment installation pit and increases the cost of the equipment foundation
