Slope clearance adjusting axial rolling device of large ring rolling machine

Abstract

A slope clearance adjusting axial rolling device of a large ring rolling machine comprises a stand and a sliding block which slides along the stand. A first clearance adjusting mechanism, a second clearance adjusting mechanism, a third clearance adjusting mechanism, a fourth clearance adjusting mechanism, a fifth clearance adjusting mechanism and a sixth clearance adjusting mechanism are arranged between the stand and the sliding block, the first clearance adjusting mechanism and the second clearance adjusting mechanism are symmetrically arranged at the left side and the right side of the front portion of the stand, the third clearance mechanism and the fifth clearance adjusting mechanism are located at the left side of the rear portion of the stand, and the fourth clearance adjusting mechanism and the sixth clearance adjusting mechanism are arranged at the right side of the rear portion of the stand in symmetry with the third clearance adjusting mechanism and the fifth clearance adjusting mechanism. The structure is capable of bearing high workload and adapting to working conditions of ring rolling of the ring rolling machine, namely a conical roller is forced during a ring rolling process, so that the sliding block bears cantilever type load, unbalance loading torque is high, and then a guiding rail bears great force. By means of slope clearance adjusting axial rolling device of the large ring rolling machine, the processing is easy, the accuracy is easily guaranteed, the clearance adjustment in use is convenient, and equipment is easy to maintain.

Description

technical field [0001] The invention relates to a hot rolling forming equipment for a seamless ring, namely a radial-axial ring rolling machine, which is an axial rolling device for the radial-axial ring rolling machine. Background technique [0002] The radial-axial ring rolling machine is a special equipment for hot rolling of seamless ring parts, that is, by applying radial and axial rolling forces to the heated blank, the wall thickness and height are reduced and the diameter is enlarged to manufacture seamless ring forgings . The axial rolling device of the radial-axial ring rolling machine, when rolling the ring, the tapered roller exerts an axial rolling force, and the slider bears a cantilever load, and the eccentric load moment is very large, which causes a large force on the front and rear guide rails. For the axial rolling device of the traditional ring rolling machine, due to the long stroke of the slider and the limitation of equipment space, there is no gap ad...

AI Technical Summary

Problems solved by technology

But there are the following defects: in order to ensure the installation of the zigzag dynamic and static adjustment plate, there are specific requirements for the form of the frame, the frame cannot adopt a box structure, and the rigidity and strength of the frame are reduced; the gap between the front and rear of the slider is directly driven by push-pull screws The structure, due to the limited force of the screw, is not suitable for the huge load on the front and rear guide rails; the key part used to adjust the left and right clearance of the slider has a zigzag dynamic and static adjustment plate with more than a dozen or more serrated surfaces. Parallel and accurate positional relationship, the requirements for machining accuracy are very high

[0004] 200910229371.6 Invention patent "guiding device for tapered roller box on ring rolling machine", also designed a cooperating zigzag inclined surface, set 4 guide rail surfaces on the frame, the angle between the guide rail surface and the two sides of the slider is 45°, This type of guide rail increases the force of the guide rail to 1.414 times. It is not suitable for the working conditions where the slider is subject to a large eccentric load moment and the front and rear of the guide rail are subjected to a large force, which will aggravate the wear of the guide rail and increase the friction.
