/.5 War/76y? ZTEVEN6ON HNDLA TEE,
Filed March 26, 1958 Patented Dec. 20, 1938 GUIDE DEVICE Stevenson Findlater, McKeesport, Pa., assignor to National Tube Company, a corporation of New Jersey Application March 26, 1938, Serial No. 198,307
4 Claims.
This invention relates to apparatus for making metallic tubular work-pieces, and more particularly to guide devices therefor.
In my copending applications, Serial No.
5 100,535, filed September 12 1936, and entitled Apparatus for making tubular work-pieces" and Serial No. 112,588, filed November 24, 1936, and entitled Guide device, there are disclosed sectional guide devices for tube rolling mills. The device of the present application is generally similar thereto but is designed to more readily permit changing the guide device to accommodate work-pieces of various sizes.
It is among the objects of the present invention to effectively sectionalize seamless tube rolling mill guide devices and provide for their eflicient support as a unitary structure; the guiding sections or elements being relatively small to eliminate large discards of unworn parts.
It is a further object of the present invention to provide a sectionalized seamless tube mill guide device in which the worn sections are readily replaced and which is capable of being quickly and downwardly and forwardly projecting lug l6 having a downwardly and forwardly inclined face I? which, together with the supporting surface l8 of r the chair I, defines a reentrant angle l9.
Adapted to be disposed on the chair I and held 5 in place between the surface M of the bell-crank lever 5 and in the reentrant angle I9 is a guideelement holder 2| which can vary in depth to accommodate the guide to a large range of pipe sizes. Guide-element holder 2| has a pair of forwardly and rearwardly extending lugs 22 and 23. Forward. lug 22 has a forwardly and upwardly inclined surface 24 which is complementary to the surface l4 on the bell-crank 5 while the rearward lug 23 which is adapted to be disposed in the reentrant angle has a rearwardly and up-- wardly extending surface 25 which is complementary to the inclined surface I1.
The rearward and lower part of the guideelement holder M has a downwardly and forl wardly projecting portion 36 having an upwardly readily changed to provide different sized guide passes.
The foregoing and further objects will be apparent after referring to the drawing in which: The sole figure is a sectional elevation of the device of the invention as applied to a conventional type of seamless tube mill.
Referring more particularly to the drawing, the numerals l and 2 respectively designate upper and lower chairs'for the-guide devices of the present invention, which are disposed above and below the pass-line of the mill and intermediate the metal-working rolls.
According to the teachings of the invention, the upper chair I carries a horizontally extending pin 3 disposed adjacent the inlet end of the mill. This pin 3 carries a movable bell-crank lever '5, one end of which extends rearwardly and generally horizontally as shown at 6. One end of a vertically extending shaft 1 is pivotally connected;
as at 8, to the end 6 of the bell-crank lever 5. The otherend of the shaft 1 is shown as extended through an ear 9 which may be integrally formed on the upper chair I. This end of the shaft 1 is screw-threaded to carryan adjusting nut l 0 in contact with the ear 9, whereby the bellcrank lever 5 may be partially rotated on the pin 3. The other end of the bell-crank lever 5 extends downwardly as shown at l2, and carries a rearwardly extending lug I3 whose rearward face I4 is inclined downwardly and rearwardly.
The rearward part of the upper chair I has a and rearwardly inclined surface 31 projected below the guide-element supporting surface 36 which, together with the inclined .surface 31, forms a reentrant angle 39. l 25 This guide-element holder 2| carries a horizontally extending pin 4 on which is pivotally mounted a bell=crank lever 26, one end of which extends rearwardly through the guide-element holder 2l, as. shown at 21. One end of a vertically 30 extending shaft 28 is pivotally connected,.as at 29,- to the ,end 30 of the bell-crank lever 26. The other end'of the vertical shaft 28 is extended through an ear 3| which may be integrally formed von the upper chairl. ,This end of the shaft 28 35 is screw-threaded to carry an adjusting nut 32 in contact with the ear 3| whereby the bell-crank .lever 26 may be partially'rotated on the pin 4.
The other end of the bell-crank lever 26 extends downwardly, as shown at 34. This end of the bellcrank lever 26 forms an arm 34 which has a suitably contoure dguiding surface 35 and forms part of the sectionalized guide device of my invention. The rearward end of the lower end of the arm 34 of the bell-crank'lev er 26 has a forwardly and upwardly inclined surface 35.
A guide-element 40 is adapted to be disposed on the supporting surface 38 and is of a generally trapezoidal shape in longitudinal cross-section having opposed front and rear inclined surfaces 4| and 42 which are complementary to the inclined surfaces 35- and 31 on the bell-crank lever 26 and the guide-element holder. 2|, respectively. It is therefore seen that the guideelement 38 can be rigidly clamped on the guideelement holder 2| by adjusting the bell-crank lever 26. The suitably contoured face 35 of the bell-crank lever 26 and the guide-element 39 together form the upper guiding surface of the sectionalized guide device.
The guide device can be readily changed to ac-- commodate a wide variety of sizes with a relatively small stock of parts. Thus a few sizes of the guide-element holder 2| and bell-crank lever 26 can be used to vary the size of the guide over a wide range, and smaller adjustments can be made by having guide-elements 40 of suitable thickness and contour for the various sizes of pipe rolled in the mill.
The lower chair 2 of the sectionalizedguide device of my invention is suitably recessed at the mid-portion thereof as shown at 59 and carries two horizontally extending pins 5| and 52. Pin 5| carries a vertically extending lever 54 which has a rearwardly extending lug 55 provided with an upwardly and rearwardly extending face 56.
Seated within the recess 50 is a guide-element holder 65 which may be of different depths to accommodate the guide device to a wide range of tubular work-pieces. At the forward end of the guide-element holder 65 is an upwardly extending lug 6B which is provided with forward and rearward upwardly-and-rearwardly inclined faces 6! and 68 respectively. Forward face 61 is inclined at an angle which is complementary to the face 56 of the lever 54. Rearward face 69, together. with the upper surface 69 of the guideelement holder 65, defines a reentrant angle 10. The rearward end of the guide-element holder 65 carries a horizontally ,extending pin ,53 on which is pivotally mounted a vertically extending lever 51 vwhich engages the chair 2, as at 58, and has a forwardly extending lug 59 provided with an upwardly and forwardly extending face 69.
Disposed on the guide-element holder 55 is a guide-element and holder H which has, adjacent its forward end, an upwardly and rearwardly inclined surface 12 complementary to the rearward face 58 of the holder 65 and adapted to fit in the reentrant angle .10. The guide-element and holder H has a forward upwardly projecting lug 13 of considerable length which is suitably profiled and has a guidingsurface 14 similar to the surface 35 of the bell-crank lever 26 on the upper chair I. The rearward part of the upwardly proje'cting lug 13 is mitered to provide a rearwardly and upwardly inclined surface I5 which, together with the horizontally extending supporting surface 16 of the holder portion of the guide-element and holder 1 I, forms a reentrant angle Ti.
A guide-element 89, which is similar to and preferably interchangeable with the upper guideelement 4|], is adapted to be disposed on the supporting surface 16 of the holder portion of the guide-element and holder H, and is of a generally trapezoidal shape in longitudinal cross-section having opposed front and rear inclined surfaces 8| and 82 which are complementary to the inclined surfaces 15 and on the guide-element.
with a relatively small stock of parts. Thus a few sizes of the guide-element holder 95 can be used to vary the size of the guide-pass over a wide range, and small adjustments can be made by having guide-element and holders 'II- and guide-elements 80 of suitable thickness and contour for thevvarious sizes of pipe rolled in the mill.
A cannon or circular inlet guide 99 may be suitably disposed on the forward end of the lower chair 2 and on outlet guide trough 9| on the rearward end. The outlet guide trough 9! is held in position by a clamp 92 which'is adjusted by a nut 93 on the rearward end of a rod 94 which is pivotallyconnected at its forward end, as at 95, to the lever 54 and extends rearwardly through the clamp 92. Thus it is seen that adjustment of the nut 93 not only secures the trough 9| in position but also rigidly secures guide-elements H and 89 on the guide-element holder by clamping the assembly between the lever 54 and lever 51 which is forced into engagement with the lower chair 2 at 5B.
While I have shown and described a specific embodiment of my invention, it will be understood that I do not wish to be limited exactly thereto as various modifications may be made within the scope of the following claims.
