  • tapered steel disks' may be formed from a squareblank of uniform thickness with a minimum amount of waste and at a low cost.
  • Another object of our invention is to 'provide a method or process of forming tapered steel disks from a square blank of uniform thickness

  • Fig. XIII is a plan view of the blank after the third pass.
  • Fig. ⁇ XIV is a plan View of the blank after the fourth pass, and,
  • Fig. XV is a sectional view through the finished wheel disk.
  • our invention consists in rolling rectangular metal blanks of substantially uniform thickness into disks having substantially a circular periphery and which are preferably tapered from the central portion to the periphery thereof, by rolling the metal blank along a plurality of different radii from the center outwardly so as to force the excess metal radially of the blank toward the periphery thereof. This tapers the blank and also causes the periphery thereof to approach a circle.
  • @ur invention also comprises a machine for carrying out'fthis method and including a pair of-Jco-operating rolls which act upon the metal blank, one of said rolls having a substantially triangular working surface of cam formation so that points on said work-A ing surface are at progressively greater distances from lthe axis of the roll.
  • ⁇ I have illustrated a machine comprising, the upright frame members 1 and 2, in which the rolls 3 and 4 are journaled, said rolls being'driven in opposite directions from a suitable source of .power through the gears 5, 6 and 7.
  • a table 8 extends forwardly from the frame work, and is provided with Ways 10., on which the carriage 9 is slidably mounted.
  • the carriage 9 had a part 11 extending towards the rolls and adapted to support the blank A which is to be operated on.
  • An arm 12 is pivoted at its forward end be-u tween the lugs13 on the carriage 9 by means of the bolt or pin 14.
  • a pin 15 projects downwardly from the rear end. of the arm 12 and is adapted to extend through a central opening 28, formed in the blank A.
  • This arm 12 and the pin 15 serves as a means for centering the blank with reference to the carriage 9 and consequently with reference to the rolls 3 and 4.
  • a cross bar 16 ex tends between the uprights 1 and 2 at the forward part of the machine, and a stop screw 17 is threaded throughv said cross bar so that its forward end extends into a position to be engaged by the carriage 9 and serves as an adjustable stop to limit the movement of the carriage towards the rolls.
  • substantially triangular raised portion 18 is formed on the roll 4. extending from the narrow shoulder 19 disposed midway between the ends of the roll to the base shoulder 20 (see Fig. H) which extends from one edge of the roll to the other.
  • the surface of the portion 18 is, at all points, equi-distant from the axis of the roll 4.
  • a substantially triangularvportion is formed on the roll 3 and so positioned on said roll as to co-operate with the portion 18 on the roll 4. This portion extends from ⁇ the nar row shoulder 21, which co-operates with.
  • Athe roll 3 The working surface on Athe roll 3 is bounded by the parallel shoulders 21 and 24 (see Fig. II) and the lines drawn from'the ends of the shoulder 21 to the ends of the shoulder 24.
  • a notch 22 is formed centrally in the shoulder 21 so as to accommodate the centering pin 15.
  • This portion is defined by the shoulder 21, the edges of theraised portion, the arc of a circle concentric with a. notch 22 and Acovering substantially ninety degrees, and lines drawn from the ends of said arc rearwardly to the edges of the raised portion thus forming the horns 25 which are in the same cylindrical surface with the portion 23.
  • the cam surface 18 extends rearwardly to the shoulder 24,A said cam.--surface increasing in its distance from the axis of the roll continuously from the line 26 to the shoulder 24. At the edges of the cam surface 18 there are formed the beveled surfaces 27 which are widest adjacent the shoulder 24 and grow narrower as they approach the parts 25 and the line 26.
  • the blank is automatically ejected from between thc rolls by the rolling action thereof, the carriage 9 moving forwardly on the ways 1() to permit this.
  • the parts 25 in the same cylindrical surface as the art 23 extend rearwardly from the shou der 21 and prevent buckling or curling of the sheet during the rolling operation as they tend to grip the blank on both sides of the point where the compression is taking lace.
  • the beveled edges 27 are provided 1n order to reduce the compression adjacent the edges -of the surface acted upon so as to eliminate the-pronounced ridges which would otherwise be caused at this point.
  • Fig. VIH I have shown the square blank of uniform thickness from whichthe tapered disks are formed.
  • Fig. IX I have shown this blank after it has been given one pass, as illustrated in Figs. and Il, showing how the blank is elongated and given a curved outline on one edge.
  • Fig. X shows the cross-sectional dimensions of this blank.
  • the blank is now given a turn llO through one hundred and eighty degrees n outwardly ,bringing the blank to the form shown in Fig. ⁇ XIII.
  • the blank is then turned through one hundred and eighty degrees and given a pass bringing the blank to the form shown in Fig..XIV.
  • the blank I' may bei trimmed and finished at this point Without rolling it any further, but We find it desirable in many cases to give it four more. passes, along the radial lines shown in Fig. XIV, in order to eliminate the ridges and cause the periphery of the blank to approach more nearly a circle. After the rolling operation is completed, the blank may be trimmed to bring its periphery to a true circle, the flange 3 1 is pressed up' from the body of the blank and the central opening 32 punched therein thus forming the completed Wheel disk.
  • a Wheel disk of tapered cross-section may be produced'very efficiently, and at a low cost.
  • the disk is formed by a simple rolling operation Which can be quickly performed and there is practically no Waste as the square blank is brought so nearly to a circle that there is very little metal to be trimmed off.
  • the distance of which from the axis of the roll increases continuously from the apex to the base thereof, and a surface, all parts of which are equi-distant from the axis of said roll, extending in advance of and alongside of the apex of said triangular portion.
  • tapered circu lar plates comprising the rolling ofa rectangular blank of uniform thickness, successlvely, along a plurality of different radii, extending from the center of the blank, with a pressure at points in a line radial of the blank proportional to the radial distance of the part ofthe blank acted upon from the center of the blank.
  • tapered disks comprising the rolling of a rectangular metal blank of substantially uniform thickness from the center outwardly along a plurality of different radii to force the excess metal radially towards the periphery of the blank.
  • tapered disks comprising the rolling of a rectangular metal blank of substantially uniform 'thickness, from the center outwardly, along a plurality of different radii, between rolls such that the portion of the roll surface in contact with the blank increases and the distance between the working surfaces of' the rolls decreases as the distance of the-"portion of the blank acted upon from the center increases.
