ADELPHIA, PENNSYLVNA, A C-SRPOBATEON OF PEHNSYL- OF STEAIG-TEJNG TAPEBED Application filed Gctober 29, 13 21. Serial No. 511,'520.
TO (all whom it may 'oo nce'm' Be it known that I, EDWARD G. Bonn, a
` citizen of the United States, residing at clear, and exact description.
This invention relates to a process of strai htenin ta eered dislrs.
111 the rolling of tapered dislrs suitable for use in the nannfacture of cish wheels for automobiles, 1 have found that the rolling op,- eration i frequently produces wrinlles or buclrles in the tapered disk which interfere with suhsequent forming Operations.
lt is the object of my invention to provide a method of straightening such tapered disks in order to remove the wrinlrles or huclrles so as to provide a perfectly uniform tapered blank which can be successfully operated on` by dies.
Further ohjects, and ohjects relating to details and economies of operation, will denitely appear from the detailed description to follow. I accomplish the ohjects of my invention by the devices and means illustrated in the accompanying drawing, forming a part of this specication. My invention is clearly defined and pointed out in the appended claims.
the drawings, Figure 1 is a diagrammatic, sectional View illustratng my method of removing buclrles from tapered dishe.
Fig. 2 is a plan view of one of the disks before being; subjected to this process.
Fig. 3 is a plan View' of the master-pime used in this process, and e Fig. 4 is a sectional view througha master-plate and two disks, showing the means hy which two dishe may he suhjected simultaneously to this straightening operation.
In the drawing, the same reference numerals refer to the same parte throughout the several views.
l Carry out my invention by providing a master-plate having a seat or recess or 1 other surface configuration which is compleof rolls. e
rection will remove all the bnclrles but, at.
nientary in form to a perfect tapered disk. he huclrled disk is lad upon the masterlate and the two are jassed throu 'h a series Sometimes a single pass in one diother times, it is desirahle to pass the masterpiate and the huclded disk through the rolls several times along different radii of the disk.
the drawings, I have shown a disk, 10, which is iilustrated as having a series of irre ularly arranged huckles, 11. These would interfere with the action of the dies in suhsequent forming Operations upon the disk and, therefore, it is necessary to remove these huckles. I accomphsh this by provd ing a master-plate matrix, 12, which has a conical depression or seat, 13, theren, complenentary to the perfect disk, so 'trial', when a perfect disk is laid upon this masterlato and centered relativecto this seat, 13, the hottom surface of the masterlato and the upper surface of the disk laid thereon will he parallel to each other. Jhe combined chickness is therefore suhstantially uniform. In Fig. l, at the left-hand side, I have shown a hucklecl disk centered upon the niaster-plate, 12, in cross section The master-plake with the disk applied thereto 'is then passed through set of rolls, 14:, the lower rolls of the set being driven while. a yielding pressure is aplied 'to' each of the upper rolls. These rolls are staggered with reference to each other, as shown in 1, and cause the tieiing of the disl and mastenplate as they pass through the set ofrolls. Such a machine is commonly known as a straightening machine. At the right-hand side of Fig. 1, I have shown, in cross section, the masterplate, 12, with the disk, 10, applied thereto,
another form of masterlato, 15, which is` adapted to straighten two disks at a single operation. This masterlato, 15, has a conical seat, 16, on each surface thereof, said oonical seat-s being complementary to the perfect disk so that when perfect disko are positioned in these seats the exposed surfaces of the disls, 10, are parallel to each other, as shown in Fig. l. The process of removing the buckles is the same with this master-plate as with the one previously described. A pair of huckled disks, 10, with the master-plate, 16, between them, are passed s in the (hs is are removed. ie term ot master-pinte te he preterred, not only lhccause it, is qucher, since two dishs may he treated at nec hu* also I ecause the disks are subjecte to a greatcr tiexing and the huchies i `lat ali bu 'ki .jhewn in Fig. i
seem to he IelllOYCd more e't'ectiveiy.
in some cases, I pass the (hsks through these relis while coht but 'he same pr may he used With tilsiS that are heated. i he dish; and IHRSG-Diflt@ rain' he passed U vw? i A .i ulltiwll the iolls one ei ;nere times alon wheel disks.
