SU537721A1 - Centering device for rolling mill - Google Patents

Description

This is achieved by the fact that in the centering sleeve 9, while the lubricant-cooler

device of the rolling mill, including a hydraulic wedge (hydraulic bed, body, the trunnings of which have a statutory cushion) between body 3 and

flax in the guide frame on the elastic, centering sleeve 9, forming a kin -

pre-compressed supports, and is located - 5matic couple,

in the housing on the rotation support, the direction of the heated lubricant is continuously removed

bushing having an internal cone through the gaps of the kinematic pair and the surface, the rotational support is guided by a new batch of lubricant-cooler,

bushings in the body are made in the form of a subtype: - supplied through nozzles 8, providing

nickname of liquid friction. High-quality cooling system.

FIG. 1 shows the proposed device. Approaching the critical speed.

in general view; in fig. 2 - the same, the view in the pipe rotation is observed to increase dynamically; in fig. 3 shows section A-A in FIG. 2; naenical loads on the centering device. FIG. 4 shows a section BB in FIG. 3.When dynamic loads are reached

The centering device consists of a stationary strut of elastic and dynamic NINA 1, in guides 2 of which at an angle of the rolls-tube-centering center oL, equal to the angle of feed of the rolls of the stand to the axis, changes the characteristics of its resonant rolling, , its pin-frequency. This eliminates the appearance of resonances resting on -. The other supports (springs) of JQ effects when the tube rotates in the range of 4, located in the 5. working speeds of the mill, which provides

The spring preload compression force 4 is reliable and durable, the centering is controlled by the tensioning system 6, for example, the device reduces the beating of the pipe, and

measures screw-nut. The horizontal axis of the hull, reducing its diversity in wall thickness, increases with the position of the abutment 7, establishes the quality of the rolled metal on the base 1.

Claims (1)

To the internal cavity of the body, made of profiled, tangentially summarized-Formula of the invention are the pipes 8 of the supply of lubricant - cooler. A centering device of a rolling mill the spigot sleeve 9, having an internal conic, including a frame, a body, pins, is a tangle-like surface, with its bell-face mounted in the guide frame the sleeve is directed towards the approach to the price — yes, of elastic, pre-compressed supports; the rolling device is rolled and placed in the housing on the support of the rotary shaft 10.35, a guide bush with an internal centering device works with a thin conical surface, which is furthermore so that, in order to increase Into the internal cavity of the housing through the service life, the rotation support is directed tangentially located 8p sleeves nozzles in the body are designed as continuously under pressure is supplied lubrication friction-bearing, coolant. .Information sources received at a detailed helical movement during examination.
