Description
Dec. 3, 19429. i w. C, CORYELL ROLLING MILL Filed April 5, 192s` gwvcwoz Wa Cory@ u,
Patented Dec. 3, 1929 UNITED 7 STATES PATENT OFFICE WILLIAM C. COBYELL, OF YOUNSTOWN, OHIO, LSSIGNOB TO CENTRAL .ALLOY STEEL CORPORATION, OF IASSILLON, OHIO, A CORPORATION OF NEWv 'YORK ROLLING MILL lApplication led April 5, 1928. Serial No. 680,121.
This invention relates to rolling mills, more particularly of the type adapted to carrying out the method of reducing metal to provide relatively thin metal strlps used for making endless belts, and other purposes in the manner described in my co-pendmg application Serial No. 411,295 filed September 18, 1920, and my former Patent No. 1,309,244 'dated July 18, 1919. l
A primary object of the inventlon 1s topprovide a rolling mill construction wherein both the reducing rollers and the main compression rolls are positively driven, thus obviating relative slippage between the rolls and rollers in the reducing operation. In that connection it is pointed out that the construe-i tion and arrangement of the rollers in the present invention are more especially adapted to producing a continuous strip which may be made into the form of a belt by weldingl plication above referred to.
A further object of the invention is to provide a. novel arrangement of reducin rolls and main compression rolls, the latter aving or otherwise as shown in my co-pending apa special non-frictional mounting which ma-' terially reduces the amount of power required for driving and contributes generally to the eiiiciency of the mill. 3o With the above and other objects in view which will more readily appear as the na-l ture of the invention is better understood, the
same consists in theI general construction,
combination, and arrangement of parts, hereclaimed. i
A preferred and practical arrangement is shown in the accompanying drawing, in which Figure 1 is a vertical cross-sectional view taken at right angles to the axis of the rolls.
Figure 2 is a vertical cross-sectional view.
Similar reference characters designate corresponding parts throughout the several figures of the drawings.
As previously indicated the present mill is particularly adapted forthe production ot' thin metal strips which are made by rolling or pressing the rough stock preliminarily while the same is hot, the finishing work beinafter more fully described, illustrated and Ving performed while the metal 'is at a lower temperature, or when it is cold.
Referring more particularly to the drawings Iit will be observed that the main compression rolls A and B are 'mounted in a suitable frame C so as to be relatively adjustable, as for exam le in the general manner proposed in'my atent No. 1,221,029 dated Apri1'3, 1917, and have arran d therebetween the reducing rolls A an B. lThese rolls are carried in the same 'blocks as the main rolls and are adjustable therewith to povide the desired pass for the metal bar according t-o the amount of squeezing or reducing required.
The main compression rolls A and B each preferably consist of a shell or hollow cylinder 1 mounted upon a bearing member or mandrel 2 b thel anti-friction bearin elements 3 whic 'may be roller bearings o conventional-form. Thus, the shell 1 of each of the maincompression rolls is mounted to be freely Vrotatable upon a bearing member orl mandrel, and at one end of each shell there is formed a gear ring 4 while at the op osite end there is provided another gear ring 5. The latter gear ring of each compression roll unit is adapted to mesh with a gear ring 6 provided at the end of one of the reducing rolls, thereby positively'driving both of said rolls Jfrom the main compression rolls.
As will be observed from Figure 2 the shells 1 of the main compression rolls A and B are coeXtensive in length with the reducing rolls A and B so that the full compressive force of the compression rolls are transmitted to the reducing rolls.
From Figure 1 it will be observed that the shells 1 of the main compression rolls A and B are driven by the gears 7 which engage with the gear rings 4 of the shells. Therefore, each of the main compression roll units A and B is positively driven and in turn each shell positively drives its reducing roll. By this arrangement the rolls A and VB are interlocked positively with ,the shells of the main rolls so that there is no chance of the -nietal M passing between the rolls A and l and between the rolls by the rotation of the main compression rolls.
A pulling device P is associated with the metal strip C andA exerts a stretching or pulling force on the strips simultaneously With the compressive force exerted by the rolls and reducing rolls.
Since the rolls A and B are positively interlocked with the main driving rolls A and B the tension imposed on the strip S will not cause the rolls to slip, thereby insuring that all of the metal is subjected to the desired squeezing. l s
In connection with the shells 1 of the main compression roll units A and B it is pointed out that the gear rings 4 thereof will always mesh with `the driving gear 7 Without disturbing the proper gear relation therebetween. 'Ihat is to say the aXis of the driving gears 7 lies in a vertical plane at one side of.the vertical plane intersecting the axes of the roll units A and B, and therefore i a horizontal plane at right angles to the said vertical plane intersecting` the roll axes, thus permitting vertical roll adjustment or movement Without affecting the proper relation of the gears.
From the foregoing it is believed that it will be clear that the arrangement proposed provides a construction wherein the reducing rolls A and B are positively'interlocked with the maincompression rolls A and B` thereby preventing relative slippage of the rolls A and B under the-tension of the pulling device, and compelling all of the fibres of the metal to be properly compressed and definitely fed between the rolls A and B at the'desired speed. In this Way treatment of the metal is fully controlled and a uniform product is insured.
Without further description it is thought that the features and advantages of the invention Will' be readily apparent to those skilled in the art, and it Will of course be understood that changes in the form, proportion and minor detailsof construction may p contact with the periphery of the'shell, and
be resorted to Without departing from the spirit of the invention or scope of the appended claims.
I claim l. A rolling mill including a pair of relatively adjustable main compression rolls, each roll including a stationary supporting member, a cylindrical shell, a gear ring provided at one end of the shell, a driving gear engaging with said gear ring, a gear ring at the opposite end of the shell, reducing rolls 1n a gear. at one end of cach reducing roller 'for engaging one of the gears on'a shell.
2. A rolling mill comprising a pair of relatively vert-ical adjustable main compression rolls, each provided with gear rings at its opposite ends, a driving gear meshing with the gear ring at one end of each roll and dissignature. Y
