Abstract
The invention relates to an upper roll balance gear which comprises supports, a rack, a balance cross beam and an upper roll, wherein the supports are connected to two sides of the rack, and the lower part of the balance cross beam is connected with the upper roll. The device further comprises balance oil cylinders which are symmetrically arranged on the supports on two sides of the rack, and hinged with the balance cross beam. According to the upper roll balance gear, the two balance oil cylinders are symmetrically arranged on the supports on two sides of the rack, so that during normal operation, the acting force of the balance oil cylinders is upward all along, the balance pressure is adjustable, the balance oil cylinders cannot only balance the weight of the upper roll, but also can eliminate a gap between a screw-down screw rod and a screw box, accurate display of screw-down stroke is facilitated, and the upper roll balance gear is simple in structure, balances the weight of the upper roll, and improves the pressing accuracy.
Description
Technical field
The present invention relates to a kind of servicing unit of heavy section steel rolling equipment, relate in particular to a kind of top-roll-balance arrangement.
Background technology
At present, in the operation of rolling because manufacturing technology limited, and service time long after, depress between screw mandrel and the screw box and have the gap, so the degree of accuracy of depression stroke is difficult to guarantee, be difficult to the weight at balance topping roll two ends simultaneously, influence the qualification rate of product, operating efficiency is not high.
Summary of the invention
The top-roll-balance arrangement that the present invention to provide a kind of simple in structure, balance topping roll weight in order overcoming the above problems, to have improved the rolling degree of accuracy.
Technical scheme of the present invention is: comprise bearing, frame, equalizer and topping roll, described bearing is connected the both sides of frame, the equalizer bottom connects topping roll, this device also comprises balancing cylinder, described balancing cylinder is symmetricly set on the bearing of frame both sides, and hinged with equalizer.
The bearing of the present invention in the frame both sides is symmetrical arranged two balancing cylinders, and during operate as normal, the active force of balancing cylinder makes progress all the time, and equalizing pressure is adjustable.Balancing cylinder not only can the balance topping roll weight, and can eliminate the gap of depressing between screw mandrel and screw box, be conducive to the accurate demonstration of depression stroke, the present invention is simple in structure, balance topping roll weight, improve the compacting degree of accuracy.
Description of drawings
Fig. 1 is structural representation of the present invention.
1 is bearing among the figure, the 2nd, and balancing cylinder, the 3rd, frame, the 4th, equalizer, the 5th, topping roll.
The specific embodiment
A kind of top-roll-balance arrangement, comprise bearing 1, frame 3, equalizer 4 and topping roll 5, described bearing 1 is connected the both sides of frame 3, equalizer 4 bottoms connect topping roll 5, this device also comprises balancing cylinder 2, described balancing cylinder 2 is symmetricly set on the bearing 1 of frame 3 both sides, and hinged with equalizer 4.
Claims (1)
