    1534882 Roller entry guides BRITISH STEEL CORP 15 Oct 1976 [17 Oct 1975] 42740/75 Heading B3M A roller entry guide for a rolling mill incorporates a pair of rollers 23 which are biased towards each other with a substantially constart force, irrespective of lateral displacements of the rollers by a workpiece. In one arrangement, the rollers are carried by two arms 19, 20 (Fig. 1, in plan) which are pivotally supported at 25 to a guide frame 10 The ends of the arms remote from the rollers have L-shaped plates 52 attached to them, and are biased apart by a hydraulic unit 58. After initial pressurization of the hydraulic unit, to provide a desired biasing force for the rollers, the force is maintained constant by a compressedgas container 59. In an alternative form (Figs. 3, 4, not shown) composite bolts embodying Belleville springs act against the arms to provide the biasing force.

    (54) INPUT ROLLER WIRING OF THE WORKING CELL OF A ROLLING MILL
    Kami adjusting screws 11. The accumulator system includes a hydraulic accumulator 12 mounted on the wiring housing, a tee 13, a valve 14 and a quick disconnect coupling 15.
    Between the ANGLES 9, it is possible to install a sensor for measuring the distance between the roller holders, which is equal to the size of the rolled car rolls. : In order to limit the approach of the roll holders {after removing the dipstick), an adjustable stop 16 is used which passes through the fork of one roller holder and rests against the fork of the other. .
    In operation, the battery 12 is initially charged to a certain pressure with compressed nitrogen (nitrogen cylinder not shown). Then, using a manual pump (not shown) connected to the quick-disconnect coupling 15, when the valve 14 in the hydraulic system is open, a pressure is created at which the force in the measuring rod between the roller holders reaches a predetermined value. After that, the valve 14 is closed and the pump is disconnected from the coupling 15. The battery 12 maintains the MS2 by the hydraulic cylinder 10 in the system at a constant pressure throughout the entire range of expected relative lateral movements of the roller holders. The constant force from the hydraulic cylinder is transmitted to the rollers 3 through the angular bars 5. and the roller holders 2. Since the same pressure is created in both areas of the hydraulic cylinder, the same forces are always applied to both sides of the workpiece from the roller side. If, for any reason, the alignment of the rollers relative to the roll of the mill rolls is disturbed, then the forces applied by the rollers 1, s to the workpiece, will be different. In this case, both rollers will begin to shift until the forces applied by them to the workpiece are equalized. This will obviously happen at that moment when the rollers and the workpiece will again be located on the axis of the roll of rolling mills.

    Invention Formula
    Input roller wiring of the rolling mill working stand, comprising a housing inside which roller holders are installed, made in the form of double-arm levers, one arm of which is equipped with guide rollers, and the other is interconnected with the distributor mechanism located on the wiring body, and their adjustment L and so that, in order to ensure the constant force of the guide rollers pressed to the transported car when changing the size of the latter, the expansion mechanism is made in the form of a double plunger gi ravlicheskogo cylinder with its accumulation of the secondary power system.
