ATTORNEY Patented Mar. 1, 1932 UNITED STATES PATENT OFFICE LEO LORENZ, F M'USKEGON, MICHIGAN, ASSIGNOR T0 ANACONDA WIRE AND CABLE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF DELAWARE ROLL FOR WIRE DRAWING MACHINES Application m January 27, 1931. Serial a... 511,467.
This invention relates to improvements in wire drawing machines and aims part1cu larlyto provide a drawing roll made ofhght parts including removable wear-resistlng [5? rings which can be readily detached and re placed as they become worn from service.
Heretofore wire drawing rolls have been formed in a single piece having a plurality of steps of different diameters. In the drawing of wire, it is essential that the outslde diameter of the successive steps be maintained uniform. The relationship between the diameters of the successive steps is commensurate with the reduction of diameter and longation of the wire drawn. Heretofore when the steps of the roll became slightly grooved or worn, it has been found necessary to turn down or grind each of the several steps. Such turning down or altering of the diameters of the steps of the drawing rolls naturally changes the draft of the entire wire drawing machine. This results in the necessity of making many alterations and changes and also causes considerable confusion.
My improved wire drawing roll includes a plurality of rings whose diameters vary by predetermined increments and these rings are removably mounted on suitable supporting members which are adapted to be rotated by any suitable means. The rings are preferably though not necessarily made of hardened or tempered spring steel which has a greater resistance to wear than ordinary turned cast iron orsteel drawing rolls heretofore made. However, when any one ring of a plurality of rings becomes grooved or I worn the individual ring can be removed and discarded and anew one substituted without .ment will be fully apparent from the following specification when read in connection with the accompanying drawings and will be pointed out withparticularity in the g appended claims.
in the drawings j Fig. 1 is a skeleton view illustrating sufi-' cient elements of a wire drawingmachine necessary for an understanding of the invention;
Fig. 2 is an enlarged longitudinal sectional view through a wire drawing roll embodying the invention;
Fig. 3 is an} enlarged detail illustrating features of construction;
Fig. 4 is a fragmentary section on line 4-4 of Fig. 2.
Referring in detail to the drawings, the wire drawing machine includes a plurality of drawing rolls, indicated at A, B, C, D, E and F. A supply reel S carries the wire which is to be reduced in diameter. This wire is drawn by the rolls A, B, C, etc., through dies R, R, R R etc., in a manner to be hereinafter described and the final product is a wire of greatly reduced diameter which is reeled up on a take-up roll T.
The rolls A, B, C, etc., are of similar construction and a detailed description of one will sufiice for all. As illustrated particularly in Fig. 2, the drawing roll comprises a plurality of rings numbered 1 to 6 inclusive. These are of different diameters, ring 1 being the smallest and ring 6 being the largest. These diameters increase by varying non-uniform increments, the increment between any two rings depending upon the-cross sectional reduction of the wire and the elongation thereof. While not wishing to be limited thereto, I prefer to form the rings of spring steel which may be suitably tempered or hardened in order to resist wear. The rings are detachably mounted preferably being seated in grooves of special form. For example, the
The centering seats for the rings are preferably of slightly undercut form, as illustrated in Fig. 3 so as to ensure a close tight fit between the ring and the adjacent supporting disc. The slot 8 illustrated in Fig. 3 is of annular, triangular form. The angle of undercut is slightly exaggerated as indicated at a: in Fig. 3. This angle in practice will usually be about 3. As thus undercut, the innermost portion 18 willbe of slightly greater diameter than the outside diameter of the ring. In this way, a clearance will be provided so that the corner 19 can make an extremely snug fit against the outer periphery of the ring. The face 20 of the triangular groove 8 is disposed at an angle y of about 60. This angular form of slot serves as a guide for assembling or forcing the parts into position and provides a construction whereby the tightening up of bolts 16 wedgingly presses the outer periphery of the ring a ainst the corner 19. This wedging action eing possible due to the inclination of the surface 20 and the relieved or undercut angle :20. In wire drawing machinery, it is important that such a tight joint between the ring and the disc are secured so that there will be no op- V portunity for the drawn wireto catch at the point of junction between the ring and the In operation, the wire to be drawn from the supply reel S first passes through the die R. It is then wrapped several times around the ring 1 of the roll A. It then passes through a suitable die opening in the die R and around the ring 1 of the roll B. It is wrapped several times around thering 1 and then passes through another die opening in the die R, thence around the ring 2 of the roll A. Then again through another opening in the die It and around ring 2 of the roll B. And so on for the various rings of the rolls A and B. From the largest ring of the roll B, the wire then passes through the die R to the smallest ring of the roll C. It is wrapped several times around this ring and then passes through die R to the No. 1 ring of roll D and soon finally from the largest ring of roll D through die R and in a manner similar to that above described around the rings of the rolls E and F through the die R At each pass through the die, it will be understood that the wire is reduced in diameter and at the same time elongated. It will also be understood that the increment of increase in diameter between the various rings is commensurate with the reduction in cross section of the wire. The final product is reeled up suitable means on a take-up reel T. rom the foregoing, it will be understood that when any given ring becomes grooved or worn in use it can be replaced without the necessity of replacing any other rings. will also be understood that because of the peculiar undercut seats formed in the discs, the rings can be closely seated in contact with the discs in such a way as to prevent any likelihood of the wirecatching therein. The skeleton construction described is also of extremely light weight which is advantageous in machines for drawing very fine wire as it permits rotation of the parts at a high rate of speed without material loss of power and with a minimum vibration.
While I have described with great particularity the s ecific details of the various embodiments o the invention herein illustrated it is not to be construed that I am limited thereto since various changes and substitution of equivalents may be made without departing from the invention as defined in the appended claims.
What I claim is 1. A wire drawing machine roll adapted to draw a wire through a die to reduce the diameter of said wire, comprising a ring about which the wire is adapted to be wrapped, a disc having a triangular undercut annular groove adjacent its periphery forming a seat for engagement with an edge of the ring and means for forcing the ring tightly in engagement with said seat to cause the 'outer periphery of the ring to abut tightly against the outer edge of said groove.
- 2. A roll of the character described comprising a plurality of discs having respective annular grooves adjacent their peripheries undercut in cross section and forming seats, rings engaging said seats and means for clamping the rings and discs in assembled relationship, whereby the outer edge of each undercut groove is held firmly in abuttment with the outer periphery or operative surface of each ring.
3. A roll of the character described comprising a pair of discs, each having a groove adjacent its periphery undercut in cross sec tion, a thin spring steel ring whose opposite edges enter the grooves in said discs and bolts passing through said discs and detachably securing the parts in assembled relationship, said bolts holding said riscs firmly against the edges of said rings with the outer edges of said grooves engaging the outer peri hery of said rings.
11 witness whereof, I have hereunto signed my name.
