Abstract
Description
- This invention relates to a turn-over cooling bank for metal stock. During the manufacture of metal stock, particularly that having a square or rectangular cross section, it is hot rolled or continuously cast and then cut to length. The stock is then allowed to cool on a cooling bank during which time it is displaced intermittently along the length of the bank. It is also desirable to rotate the stock as it moves along the bank so that it cools more uniformly and thereby avoids distortion of the stock.
- A turn-over cooling bank is disclosed in DE-A-1427897 in which there are a carrier rack and a pick-up rack arranged substantially horizontal and side-by-side. Each rack has a notched surface and means are provided for providing both racks with a reciprocating vertical travel with the two racks being moved simultaneously 180° out of phase with each other. Separate eccentrics are provided whereby the two racks are reciprocated horizontally with a fixed or adjustable stroke, but out of phase with each other, whereby each rack moves along an elliptical path and stock lying on the racks is rotated as it is moved along the cooling bank. Although the specification states that both the horizontal and vertical components of the movement of the rakes can be made variable, there is no indication in the specification as to how this can be brought about and one has to assume that it is brought about by physically removing the eccentrics from their operating shaft and replacing them with eccentrics having a different sized throw. Clearly, this is not a very easy operation.
- If the cooling bank is to accommodate stock of differing cross-sectional dimensions, then it is necessary to be able to adjust the horizontal travel of one rack with respect to the other rack.
- It is an object of the present invention to provide a cooling bank of this type which can accommodate stock of a wide range of cross-sectional dimensions.
- According to the present invention, a turn-over cooling bank for metal stock comprises:-
- (a) a carrier rack having a notched support surface arranged substantially horizontal;
- (b) a pick-up rack having a notched support surface arranged substantially horizontal and side-by-side with the carrier rack;
- (c) means for providing both racks with a reciprocating vertical travel of a fixed stroke with the two racks being moved simultaneouly 180° out of phase with each other;
- (d) means for providing one of the racks with a reciprocating horizontal travel of a fixed stroke; and
- (e) means for providing the other rack with a reciprocating and adjustable horizontal travel which is out of phase with the first rack whereby the horizontal and vertical movement of each rack is such that it moves along an elliptical path and stock lying on the racks is rotated as it is moved along the cooling bank, said means including a rotatable drive shaft and an inner member secured to the drive shaft and eccentrically mounted with respect thereto, characterised in that an outer member is eccentrically mounted on the inner member and rotatable with respect thereto and there are means for rigidly connecting the inner and outer members together at a selected one of a number of angular positions of the outer member with respect to the inner member whereby the stroke of the horizontal travel of the rack is adjustable between predetermined limits.
- In use, the stock is picked up at the entrance end of the bank on the notched support surface of the pick-up rack, moved forward, and deposited on the notched support surface of the carrier rack. This motion continues to move the stock progressively to the exit end of the bank. The notches on the two racks are so shaped that, each time the stock is deposited on to the pick-up rack, it is turned about an axis parallel to its length. The angle through which the stock is turned is usually 90°. If the bank is to accommodate stock of differing cross-sectional dimensions, then it is necessary to be able to adjust the amount of forward travel of the stock as it is moved by the carrier rack and deposited on to the pick-up rack. This is to make sure that the stock is deposited on the correct part of the notched support surface of the pick-up rack so that the stock turns over through the correct angle without excessive sticking and bumping which would damage the stock and the support surface of the racks.
- In order that the invention may be more readily understood it will now be described, by way of example only, with reference to the accompanying drawings, in which:
- Figure 1 is a side elevation of part of the turn-over cooling bank,
- Figure 2 is a side elevation of a further part of the turn-over cooling bank,
- Figure 3 is a plan of the part of the bank shown in Figure 2,
- Figure 4 is a plan of the drive arrangement for the cooling bank,
- Figure 5 is a plan of part of the drive arrangement of the carrier racks,
- Figure 6 is a side elevation of the double eccentric device shown in Figure 5, and
- Figure 7 is a side elevation of part of the drive arrangement for the carrier racks.
- Referring to the figures, a turn-over cooling bank for metal stock, generally of square cross- section and say 100-160 mm length of side, includes a plurality of carrier racks 1, of which one is shown in the figures. These racks are of elongate form with a notched
upper support surface 3. The racks are arranged in parallel, side-by-side, spaced apart relation and each rack has a number of downwardly extendingbrackets 5 spaced apart along its length. The corresponding brackets of all the carrier racks are connected totransverse beams 25. A shown in Figure 7, thetransverse beams 25 are connected together byunderslung tie beams 24. A plurality of pick-up racks 7, of which one is shown in the figures, are arranged in parallel, side-by-side, spaced apart relation and are interdigitated with the carrier racks 1. These racks have a notchedupper support surface 9 and each rack has a number of downwardly extendingbrackets 11 spaced apart along its length and the corresponding brackets of these racks are connected bytransverse beams 27. Thebeams 27 are connected together byunderslung tie beams 26. - Referring particularly to Figures 2 and 3, the
beams roller track rocker unit 29, consisting of a fixedpedestal 31 having a pair ofrocker plates 33 pivotally mounted thereon, and connected together by two pins each carrying aroller 35. One roller engages the underside of thetrack 27A beneath thebeam 27 and the other roller engages the underside of thetrack 25A beneath thebeam 25. A mechanism, to be described in more detail later, is employed to rock theplates 33 relative to the fixedpedestal 31 to reciprocate therollers 35 in a vertical direction with the rollers being out of phase, that is, as one roller is raised, the other is lowered. The movement of the rollers causes the carrier racks 1 to be reciprocated up and down 180° out of phase with the up and down movement of the pick-up racks 7. - The reciprocating movement of the
rollers 35 is brought about by a drive means which includes arotatable shaft 15, mounted substantially horizontally in fixedbearings 17. An eccentric 41 is mounted on theshaft 15 and alift arm 39 is mounted on the eccentric. The lift arm is connected byrespective links 37 to pivots on theplates 33. As the shaft is rotated, the eccentric causes thelinks 37 to reciprocate substantially horizontally and to pivot therocker plates 33 with respect to thepedestals 31. - Referring again to Figure 1, a mechanism is shown for causing all of the racks 7 to be moved together in a horizontal direction. The mechanism includes an eccentric 19, mounted on the
rotatable shaft 15, and anarm 21 engages with the eccentric. Alink 23 connects thearm 21 to a part of thetie beam 26 which is positioned beneath one of thetransverse beams 27. Rotation of the shaft causes the framework, including thetie beam 26 andtransverse beams 27, to reciprocate in a substantially horizontal direction with a fixed stroke. Since the racks 7 are rigidly secured to thebeams 27, the racks 7 also reciprocate in a horizontal direction with a fixed stroke. The horizontal reciprocation of thebeam 27 is arranged such that, throughout the horizontal reciprocation, thetracks 27A remain in contact with therollers 35. The pick-up racks 7 are thus subjected to both vertical and horizontal reciprocatory movement simultaneously and, consequently, the actual movement of the racks 7 is along an elliptical path. The stroke, both the vertical and the horizontal movements applied to the pick-up racks, is fixed and, consequently, the shape of the elliptical path is fixed. - Referring to Figure 7 again, a mechanism is shown for providing horizontal reciprocatory movement to the carrier racks 1. A double eccentric device, indicated generally by
reference 42, is mounted on theshaft 15 and is connected by alink 44 to part of thetie 24, which is positioned beneath one of thebeams 25. On rotation of the shaft, a reciprocatory horizontal movement is provided to thebeams 25 and, consequently, to the carrier racks 1. This reciprocatory horizontal movement supplied to the carrier racks is of a fixed stroke but this stroke can be adjusted. - Referring particularly to Figures 5 and 6, the drive means for providing the horizontal reciprocatory movement includes an
inner member 43 rigidly and eccentrically mounted on theshaft 15. In the arrangement shown, themember 43 is offset by 35 mm with respect to the axis of rotation of theshaft 15. Asecond member 45 is eccentrically mounted on themember 43 and is rotatable with respect thereto. In the arrangement shown, the offset between themembers member 45 has aflange 47 which fits over one edge of themember 43, This edge of the member is apertured andsimilar apertures 49 are provided in theflange 47. By rotating themember 45 with respect to themember 43, the relative offset between the two members can be adjusted between 35 + 10 equals 45 mm and 35 - 10equals 25 mm. When the required offset has been obtained, the two members are connected together by means of bolts (not shown) which pass through theapertures 49 into the apertures in themember 43. Aroller race 51 surrounds themember 45 and the eccentric movement of themember 45 is transmitted by therace 51 to anarm 53 which, in turn, transmits the movement to thetransverse beams 25 supporting the carrier racks by way of thelink 44 and thetoe 24. - For a product of given cross-sectional dimensions, the
eccentric members eccentric members - The pitch of the notches on the pick-up racks and the carrier racks, and both the vertical and horizontal displacement of the racks, are all dependent on the range of products to be transported along the cooling bank.
- The pitch of the notches on the racks is roughly fixed as being equal to the distance across the diagonals of the maximum stock to be transported plus approximately 50 mm to maintain this as a maximum gap so as not to restrict air flow for cooling purposes. The fixing of the vertical and horizontal movements required is rather more difficult but basically consists of adding the notch height of the pick-up rack to the notch height of the carrier rack and then adding 20 mm for additional clearance. Having fixed the vertical height of each ellipse in this way and the relative distance between the two racks, the ideal width of the ellipse for the maximum size stock can be established, as can the ideal width for the minimum size stock. Obviously a compromise has to be made between these sizes for the width of the ellipse, but the compromise chosen is dependent on the relative sizes of the products which are to be carried on the bank. The in-built adjustment which is permitted on a bank constructed in accordance with the present invention enables the bank to be used for a wide range of product sizes.
- Although in this specification the carrier racks have been described as having the adjustable horizontal stroke, they could be provided with a fixed horizontal stroke and the pick-up racks could be prqvided with an adjustable horizontal stroke.
