Summary of the invention
The invention provides a kind of open-rack three-roller oblique rolling extender; Adjustment often causes a deviation bigger owing to need respectively to have solved opening degree, feed angle, the rolling angle of three rolls of the three-roller type oblique milling elongator that prior art exists; Single compensating cylinder balance that adopts topping roll causes the rolling position of top roll to produce the deviation of installing, adjusting and measuring; The roll axial location of three rolls is non-adjustable; When roller is takeed on axial location because of assembling and wearing and tearing generation deviation, be difficult to correct, directly influence the technical problem of the rolling quality of hollow forging.
The present invention overcomes the above problems through following scheme:
A kind of open-rack three-roller oblique rolling extender; Comprise the elongator support; The elongator support is provided with lower bearing bracket; Lower bearing bracket is provided with that left bottom roll is depressed transmission and balanced controls, left bottom roll case, left bottom roll assembly, the bottom right roll is depressed transmission and balanced controls, bottom right roll-box and bottom right roll assembly, and upper spider is provided with topping roll and depresses transmission and balanced controls, topping roll case and topping roll assembly, on upper spider, is respectively arranged with upper left guide agency and upper right guide agency; Lower bearing bracket is provided with bottom guide mechanism; These three guide agencies with the rolling central axis of elongator be the center of circle on a concentric circles each other with radian disposed at equal distance at a distance of 120 degree, guide agency comprises that guide plate depresses transmission balance mechanism, guide plate is depressed transmission balance mechanism and is connected with the guide plate frame; The head of guide plate frame is provided with the circular arc guide plate, and three circular arc guide plates are that the center of circle constitutes a blind bore shape with the rolling central axis of elongator; The upper left side of topping roll case through first wedge and the arrival end that on upper spider, fixedly installs radially the oil cylinder piston bar of locking cylinder link together; The left downside of topping roll case through second wedge and the port of export that on upper spider, fixedly installs radially the oil cylinder piston bar of locking cylinder link together; The upper right side of topping roll case links together through the 3rd wedge and upper spider; The lower right sides of topping roll case links together through the 4th wedge and upper spider; Between the upper surface of topping roll case and upper spider, be respectively arranged with the 5th wedge and the 6th wedge, between the lower surface of topping roll case and upper spider, be respectively arranged with the first axial locking arm and the second axial locking arm of roll-box.
First wedge that is provided with between described topping roll case and the upper spider, second wedge, the 3rd wedge and the 4th wedge are movable the setting also can adjust replacing.
The axial location of roll of the present invention is adjustable, has guaranteed the uniformity of three roll backing bands, thereby has improved the rolling quality of hollow forging.
