Definitions
- This invention relates to rolling mill pouring reels for forming hot rolled products such as rods, bars, and the like into annular coils.
- product(s) In a conventional rolling mill pouring reel, rods, bars and the like (hereinafter collectively referred to as "product(s)") are directed downwardly at an angle into an annular coil forming chamber defined by the outer surface of a central mast and the inner surface of an outer tub.
- the mast and tub are rotatably driven as a single unit, and the product is gathered in the coil forming chamber as a series of superimposed rings which gradually accumulate to form an upstanding coil.
- the free fall distance through which the product drops in an uncontrolled manner will vary throughout the coil forming cycle, and this in turn will adversely affect uniform distribution of the rings and stability of the coil.
- the objective of the present invention is to provide an improved pouring reel which avoids or at least substantially mitigates these problems.
- the central mast and the surrounding tub are rotatably driven by independently operable drive mechanisms.
- the mast and tub can be driven at different speeds selected to substantially match the incoming velocity of the product being coiled.
- the tub is vertically adjustable along with the entry pipe through which the product is directed into the coil forming chamber.
- the tub and entry pipe can thus be raised gradually as the height of the coil increases. This in turn makes it possible to keep the free fall distance of the product into the coil forming chamber both at a minimum and substantially constant throughout the coil forming cycle.
- an entry guide is interposed between the entry pipe and the coil forming chamber.
- the entry guide defines a curved path which preferably is concentric with the axis of the central mast and which leads downwardly from the entry pipe into the coil forming chamber.
- the entry guide includes a plurality of hold down rollers arranged in a horizontal plane at the terminus of the curved path. The entry guide is vertically adjustable during the coil forming cycle to maintain the hold down rollers at a selected distance above the uppermost rings gathering in the coil forming chamber.
- the curvature of the guide path serves to preform the product into the desired circular configuration, and the hold down rollers serve to vertically confine rings that might otherwise be raised by virtue of being in frictional contact with the tub as it is gradually elevated during the coil forming cycle.
- Figure 1 is a side elevational view, with a portion broken away, showing a pouring reel in accordance with the present invention at the start of a coil forming cycle;
- Figure 2 is a plan view on an enlarged scale of the pouring reel as depicted in Figure 1;
- Figure 3 is a sectional view taken on line 3-3 of Figure 1 ;
- Figure 4 is a sectional view showing the tub and its drive mechanism
- Figure 5 is a sectional view showing the central mast and its drive mechanism
- Figure 6 is a sectional view showing both the coil plate and the entry guide with their respective elevating mechanisms
- Figure 7 is a view similar to Figure 1 showing the pouring reel at the completion of a coil forming cycle
- Figure 8 graphically depicts the stepped manner in which the tub/entry pipe assembly and entry guide are vertically adjusted during the coil forming cycle.
- a pouring reel in accordance with the present invention is generally depicted at 10.
- the pouring reel includes a central mast 12 lying on a vertical axis "A".
- a cylindrical tub 14 surrounds and cooperates with the mast 12 to form an annular coil forming chamber 16.
- a coil plate 18 defines the bottom of the chamber 16.
- An entry pipe 20 is arranged to deliver the product traveling at an incoming velocity downwardly at an angle ⁇ for accumulation in the chamber 16 as a series of superimposed rings forming an annular coil.
- the tub 14 is rotatably driven by a first drive mechanism including a motor 22 connected via a coupling 24 to a stub shaft 26.
- Shaft 26 carries a pinion gear 28 in meshed relationship with a ring gear 30 on a skirt depending from the tub 14.
- the mast 12 is driven independently of the tub 14 by a second drive mechanism including motor 32 coupled as at 34 to a stub shaft 36.
- the mast 12 has a downwardly extending tubular leg 38, with intermeshed bevel gears 40, 42 serving to mechanically couple the tubular mast leg 38 to the stub shaft 36.
- the first drive mechanism may be operable to rotatably drive the tub 14 at a speed at which its inner surface has a velocity substantially matching the incoming velocity of the product.
- the second drive mechanism may be operable independently of the first drive mechanism to rotatably drive the mast 12 at a speed at which its outer surface also substantially matches the product's incoming velocity.
- the coil plate 18 is carried on a vertical stem 44 projecting downwardly through the tubular leg 38 supporting the mast 12.
- a bearing 46 at the lower end of the stem 44 is engaged by the piston of a lift cylinder 48.
- the coil plate 18 projects through the side wall of the mast 12 as at 50, and is thus mechanically coupled to the mast for rotation therewith about axis A.
- the tub 14 is supported by and journalled for rotation within an outer cylindrical housing 52.
- the housing has vertically disposed external tubes 54 that are slidably supported on fixed vertical legs 56.
- a third drive mechanism comprising lift chain assemblies 58 powered by motors 60 serves to vertically adjust the outer housing 52 and the tub 14 along axis A.
- the housing 52 and tub 14 are shown in Figure 1 at the lowermost position at the start of a coil forming cycle.
- Figure 7 shows the housing and tub in the uppermost position at the conclusion of the coil forming cycle.
- a bracket 62 serves to mount the entry pipe 20 on the outer housing 52.
- the entry pipe is vertically adjustable in unison with the tub 14 and housing 52.
- the product's free fall distance "d" to the coil plate 18 can be minimized, which in turn allows the entry angle ⁇ of the pipe to also be kept relatively small, advantageous less than 14°.
- the housing 52, tub 14, and entry pipe 20 can be gradually raised while maintaining the free fall distance substantially constant to the very end of the cycle as shown in Figure 7.
- the present invention preferably includes an entry guide 64 defining a guide path 66 for the product leading downwardly from the entry pipe 20 into the coil forming chamber 16.
- the entry guide carries a plurality of hold down rollers 68 arranged in a horizontal plane "P" at the terminus of the guide path 64.
- the guide path is curved and concentric with the axis A.
- the entry guide 64 projects in cantilever fashion from a post 70 projecting vertically through a sleeve 72 carried by a fixed bracket 74.
- a motor driven gear drive 76 engages a rack 78 on the post 70 and serves as a fourth drive mechanism for vertically adjusting the entry guide.
- the entry guide 64 In its operative position, the entry guide 64 overlies the coil forming chamber 16. At the beginning of a coil forming cycle, the entry guide is vertically positioned such that the plane P of the hold down rollers 68 is spaced above the support surface of the coil plate 18 by a "control distance" slightly greater than the diameter of the product being coiled. As each product layer is deposited, the drum 14 and entry pipe 20 are first indexed upwardly by the control distance while the entry guide remains in place, allowing the hold down rollers to contact and vertically confine the underlying rings from being vertically dislodged. The entry guide 64 is then indexed upwardly by the control distance. This stepped operational sequence is depicted in Figure 8 where the solid and broken lines respectively depict vertical adjustment of the tub/entry pipe assembly and the entry guide.
- the entry guide is pivoted about the axis of post 70 to an inoperative position which allows the completed coil to be vertically expelled from the coil forming chamber.
- the present invention incorporates a number of advantageous features that contribute to the pouring reel's ability to produce more uniform and stable product coils. More particularly, the ability to drive the central mast 12 and surrounding tub 14 at different speeds that allow their surface velocities to match the incoming product velocity contributes significantly to the uniform distribution of rings within the reforming chamber.
- the ability to vertically adjust the entry pipe 20 with the tub 14 enables the free fall distance "d" to be minimized and maintained substantially constant throughout the coil forming cycle, thus further improving ring distribution.
- the relatively shallow entry angle ⁇ minimizes the extent to which the product tail end will project above the top of the finished coil.
- the entry pipe may be oscillated in the horizontal plane in order to further improve ring distribution and coil formation.
- the hold down rollers 68 of the vertically adjustable entry guide 64 vertically confine the uppermost rings from being frictionally displaced by vertical tub adjustments, and the curvature of the guide path 66 beneficially preforms the product delivered into the coil forming chamber 16.
- Pouring reels may benefit from the inclusion of some ⁇ but not all of these features.
- benefits can be derived from vertically adjusting the entry pipe 20 without also differentially driving the mast 12 and tub.
- the reverse is also true, ie., advantages may be gained by differentially driving the mast and tub, while allowing the entry pipe to remain fixed vertically.
