6 Claims.

This invention relates to reels, and more particularly to the construction and arrangement of an improved coil plate for use with -reels adapted for coiling hot metal bars.

In the coiling of wire rods and similar elongated metal products as they are delivered by a rolling mill, it is a common practice to utilize so--called pouring reels. A reel of this type ordinarily comprises a horizontal circular coil plate which can be rotated about a vertical axis, this plate having holes therein through which inner and outer rows of pins may extend upwardly. The hot metal stock is delivered to the annular space between the two rows of pins, so that the coil as it is being formed rests upon an annular area of the coil plate. This annular area of the plate becomes very hot, whereas the central and outer portions of the plate'remain comparatively cool, and this unequal heating of the plate causes warping, buckling, excessive and non-uniform growth of the metal, and eventual cracking and destruction of the plate. The problem is rendered even more difficult by the fact that the rotation of the plate must be stopped to permit removal of each completed coil, and the coil plate must therefore be made as light as possible in order to lavoid excessive inertia effects in the starting and stopping thereof.

It is accordingly one object of the invention to overcome these difculties and to provide a coil plate adapted for use in a pouring reel for coiling hot metal bars and capable of operating in a satisfactory manner throughout a long life of service.

It is a further object of the invention to provide a coil plate of comparatively light construction capable of withstanding the effect of hot metal stock thereon without harmful warping, buckling or cracking.

With these and other objects in view, as will be apparent to those skilled in the art, the invention resides in the combination of parts set forth in the specification and covered by the claims appended hereto.

Referring to the drawing illustrating one embodiment of the invention and in'which like reference numerals indicate like parts,

Fig. 1 is a top plan View of a coil plate for a pouring reel;

Fig. 2 is a section on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged section on the line 3--3 of Fig. 1; and

Fig. l is a small scale vertical sectional view of a pouring reel.

In Fig. 4 there is shown a pouring reel comprising a pin plate I0 supported on the upper end of a rotatable quill II, this quill being driven by suitable means (not shown). From the pin plate I0 an inner circle of pins I2 and an outer circle of pins I4 extend upwardly, these pins being surrounded by a stationary upright cylindrical casing I5. A vertical `rod I6 extends upwardly through the quill I I, and this rod has a flange I1 on its upper end to which there is secured a coil plate 1 9. This coil plate is apertured so that the pins I2 and I4 may extend upwardly therethrough. By rotating the quill Il and delivering the hot metal bars from a rolling mill into the annular space between the two rows I2 and I4 of revolving pins, a coil will be formed in a wellknown manner. The -coil will rest upon the coil plate I9 therebeneath, and upon completion of the coil the rotation of the parts will be stopped and the coil plate I9 will be raised by means of the rod I6 to bring the upper surface of the coil plate slightly above the tops of the pins I2, as is the common practice to allow removal of the coil laterally from the coil plate without interference with the pins.

The present invention has to do with the construction of the coil plate I9, and in the preferred embodiment illustrated this plate is formed of several parts which are connected by welding into an integral structure, but it will be understood that other methods of manufacture may be employed. The improved coil plate comprises a central hub 2| adapted to be secured to the flange I'I, this hub being welded to a surrounding annular plate 22 having .a depending flange 23 at its outer edge. These parts form a circular disk having a flat horizontal upper surface. The plate 22 is provided with an inner circle of pin holes 25 and an outer circle of pin holes 2B, there being twice the number of holes 26 as there are holes 25. The pin holes are uniformly spaced in the respective circles, and the inner holes 25 are staggered relative to the outer holes 2B. Two diametrically opposite holes 25 are reenforced by bosses 2I .which are welded to the plate 22 and extend downwardly therefrom. It will be understood that at assembly the pins I2 will extend through the holes 25, and the pins I4 will extend through the holes 26. The two bosses 21 will serve as guides to maintain proper alignment of the holes with the pins, particularly when the coil plate is raised to its uppermost position.

The annular area of the coil plate between the inner and outer circles of pin holes is subjected to a considerable heating effect from the coil of v hot metal which rests thereon when the reel is in use. In order to prevent damage to the plate from such localized heating thereof, narrow radial slots 29 of uniform .width are provided, these slots extending inwardly from the outer edge of the coil plate and terminating in circular holes 30. Each slot is located midway between two of the pinholes 25, as well as midway between two of the pin holes-26. Substantially radial ribs 3| are welded to the bottom of the plate 22 near the slots 29 and on opposite sides thereof, these ,topermita free slidingvrnovement thereof. With -this construction, the pins .38 lwillInaintainproper alignment betweenvthe plate portions on opposite .sides ofthe slots 29 .without preventing expansionrand. growth caused by heating.

VvIn.manufacturingthe coil plate, lthe hub 2l, ribsg3l, flange 23,. and bosses-33 and 34v are welded to Ythe plate 22,. each pair of bosses.33 andA 34 Abeing ,preferably lformed in kan integral block. .Thereuponthe holes 30,- are drilled and thegslots 29 are sawed,.these slots severing leachvboss 33 from -`the adjacent boss 34. The holes r35 `and 36..will nowbe drilled, ,and the pins v38 Iinserted therethrough.and-welded, whereupon the remaining -machining .operations will be performed .in- VIKcluding theV finishing4 of the top surface ofthe plate. vrIn.this manner` any internal strainswhich maybe set up in the plate by reason of the .welding thereof lwill be relieved when the slots are formed, and the pins `38 y,will be free-from any initial loading.

yIt will now be apparent that the improved coil :platedisclosed is comparatively light in V,weight and hence will notproduce undesirable inertia effects. `Although the plate is subjected to severe heating foveran lannular area while Ain service, .this will cause .no difficulties, since the slots; 29 Adivide the ,plate into relatively small sections :each of-which is freeto expand, and grow. independently. The ribs; 3| and the flange' 23 serve ,to stiifenf,and-strengthen` each plate section, and

.the pins-,38 Iserve .to maintain theplateisections in alignment while permitting relative movement of the parts in a circumferential direction.

Having thus described my invention, what I claim as new and desire to vsecure by Letters Patent is:

1. A coil plate for a pouring reel comprising a disk having holes therethrough arranged in inner and outer` concentric circles, and a plurality of slots extending inwardly from the outer margin of the disk and between the holes.
