ROLLING.
Specication of Letters Patent.
Patented April 21, 1908.
Application filed May 24, 1907. Serial No. 375,547.
To dill whom 'it may concern:
Be it known that I, vWILLIS MCKEE, residing at Elyria., in the county ofLorain and State of Ohio, a citizen of the United States,
have invented or discovered certain new and useful Improvements in Rolling?, of which improvements the following is a specification.
The invention described herein relates to certain improvements in the reduction of billets to bars, rods, etc., and has for its object the reduction of .the billet to a form in which it is divided into vlongitudinal sections by deep grooves or channels, the portions between such channels havin approximately the shape or contour an cross sectional dimensions of the finished article, and then searatingultlhese. several sections and separatey finis g the sections to the desired size and shape.
It has heretofore been customary to restated and after the several arts or sections of the billet have been brought to or approximately to the desired shape and size, to sever the sections one from the other by forcing the web conthe several sections, against a cutting e ge and then separately finishing the several parts. The severing of the sections has also been effected by passing them between rolls havingsharp collars,
jecting tions of the 4billet after it has een brought to or approximately to the desired shape or size in 'cross section to `a greater reduction and consequent .elongation than the other ,partsor sections whereby the connecting web is either ruptured or brought to such a be readily ruptured by causing; adjacent sections tojldiverge by meansy of .suitable guides after passing which will 'cut the connectin web. These methods are objectionable as t 'de th, thereby dividing the 'b to the greater elongation,
through the rolls in which the dierence of elongation is effected.
The invention is hereinafter more fully described and claimed.
In the accompanying drawing forming a part of this specification, Figure 1 is a p an view of an arrangement ofrolls for the practice of my invention, the rolls being shown in tandem but not necessarily in continuous relation to each other; Figs. 2, 3, 4, & 5 show the forms of asses in the rolls suitable for reducing the billet a proximately to the finish size and shape. ig. 6 shows a form of finishing pass. Fig. 7 illustrates in side elevation orms of separating and turning guides. Fig. 8 is an end view of the separatin guide; Figs. 9 8a 10 are end sectional views ustrating aform of guides for eifectinglthe sep aration e sections.
jected to reduction in three or more passes,
1n pairs of rolls A, B, & C whereby it is reduced in thickness, increased in width somewhat and elongated. In these passes, channels one, two or more, are suitable collars 2 on the rolls, such channels or grooves being gradually increased in billet longitudina ly into a series of two or more parts or sections a, b, c, etc., connected by webs 3. As soon as the billet has been reduced to a point Where the several sections have been brought nearly to the desired sha e and size in cross section, it is put throu another pass in rolls D. The ortions o,y the rolls D opera'- tive on the diHerent sections, are so constructed and proportioned in accordance with rules known in the art, that alternate sections, as for example the section b, is subgrooves or ormed by jected to such rolling action or reduction, I l
that it will be elongated to a greater extent than the elongation produced in other sec.
tions a and c. It will be understood of course', that in the sections a and c may be elongated to a greater extent than lieu of subjecting the section 50 ered'.
,12. In this pass the various sections are brought approximately to the final desired shape and dimensions in cross section, and b reason of the different elongation to whic 5 adjacent sections are subjected, the connecting Webs 3 are ruptured or their strength reduced to such an extent thatva divergence of the sections after passing from between the rolls will easily cause a separation of the sectlons.
havin this pass, I provide suitable guides wherey the relative positions of the sections as they come from the rolls are changed so as to insure by the strain put upon the web 3, a
severance of the latter, in case a complete severance has not been effected by the elongation as stated. In the construction shown m Figs. 1, 7, & 8, these guides are provided with deflecting portions 4 and 5, so con- {structed and arranged that adjacent sections Will be moved apart vertically, but it will be readily'understood by those skilled in the art,
that a lateral or axial movement may b'e imparted to the sections, thereby insuring a separation thereof. After being thus separated by the guides each section is passed-- se arately through between suitably grooved ro final or commercial s ape. It will be generally necessary to subject the sections after v separation to an edging ass. Hence twisting. ides 6 are provide with means Whereby t e sections may be turned axially or on edge, such axial turning bein in addition to the horizontal or vertical disp acement of the sections.
In Figs. 9 and 10 a form of twisting guides is shown adapted to effect a separation of the sections by the axial movement thereof. This guide is rovided with channels 7 which have their wa tially arallel'with the sides of the sections a, b, an c, as they come from the rolls D. These walls have a gradual twist toward the discharge end of the guides so that the sections will be turned through or approximately through an arc of ninety degrees, and in this turnin the webs, weakened, if not ruptured in roIls D, will be completely sev- It will 'be readily understood by those skilled in the art that the number of passes through which the sections, are fed after separation Will be de endent upon the transversedimensions of t e sections as they come from the rolls or passes D, and the transverse dimensions desired in the nished article.
I claim herein as my invention:
- 1 1. As an improvement in the art of rolling,
the method herein described which consists in reducing or rolling downa billet or other large'section, simultaneouslyforming twoor more connected sections of smallertranverse On the delivery side of the rolls D E etc.,.for brin'ng the article to the s at the entering end, substandimensions, land finally causing an elongation of one of said smaller sections greater than that ofad'acent sections and thereby partially or w olly rupturingnthe web between adjacent sections.
2. As an improvement in the art of rolling,
ing a greater elongation to one of the sections than that of adjacent section and then caus-A ing adjacent sections to move transversely in respect to each other, and thereby rupturin'g the connection between adjacent sections.
3; As an improvement in the art of rolling, the method herein described which consists in reducing or rolling down a billet or othei` large section' and d 0' such rolling progressively dividing the b' ongitudinal connected sections, caus` agreater elongation to one of the sections t an that of adjacent sections and then causing a separation of the sections transversely in respectato the line of feed of the billet, thereby rupturing such webs'.
4. As an improvement in the art of rolling,
et into two or more the method herein described which consists in reducing or rolling down a'billet or other large section, and d such rolling o eration progressively dividing the bil et into two or more longitudinal web-connected sec# tions, causing an elongation of one of the sections greater than that impartedV to adjacent section or sections, 'and then separating the sections by moving respect to each other.
5. As an improvement in the art of rolling, the method herein'described which consists in reducing or rolling down a billet or other large section, forming two or more Web-connected sections and causing the metal of one them transversely in ioo or more of s`u`ch sections to 'move' longitudinally with reference to an adjacent section or sections, whereby the web connecting adjavcent s ectins is wholly or partially ru tured.
6. As an improvement 1n the art ofp manufacturing bars, rods, etc., the method herein described which consists in partiallydividing abillet or other section longitudinally and so rolling the billet as to cause the metal of one of the web connected sections to move longitudinally from point to point and progressively with reference to an adjacent section whereby the connecting web is wholly or partially ruptured.
7. As an improvement inthe art of manufacturing bars, rods, etc., the method herein described which consists in partially dividing a billet or other section longitudinally, causthe metal ofone of the Web-connected sections-to move longitudinally referi ence to an adjacent section and then causing one of the sections to move transversely ci the other section. l
8f As an improvement in the art of rolling, the method herein described which consists in reducing or rolling a billet or other large section and during vsuch reduction forming and progressively 4deepening a groove or grooves thereby dividing the billet into tvvo 10 or more Web-connected sections arranged 1n a common plane, and tearing or rupturing such sections apart by causingthem to move in divergin lines during their discharge from the last bi et reducing ass.
In testimony whereo Ihave hereunto set 15 my hand.
