Definitions

  • the invention relates to a method and a device for continuously obtaining, from a non-ferrous metal blank from a continuous casting machine on a grooved wheel, ingots of constant section and having bosses at their ends. suitable for making self-blocking stacks.
  • ingots having hollow and / or raised portions on one or more of their faces can be produced from molds of suitable shape, in order to prevent any relative movement of the ingots with respect to each other when they are assembled in the form of stacks and thus making their transport convenient.
  • the process according to the invention consists, in a known manner, of casting a blank on a grooved wheel temporarily closed by a ribbon and periodically making this blank integral with a device responsible for sharing it in ingots, but it is characterized in that that the blank is first clamped progressively on two opposite longitudinal side faces using two jaws in order to form imprints in line with these jaws, these imprints each comprising an edge extending over the entire height of the blank, and to develop at least one boss on at least one of the two other lateral faces, the boss or bosses being in a transverse plane passing through the imprints, the blank then being sheared in line with the imprints.
  • the method uses, as a raw material, a blank from a casting machine on a grooved wheel temporarily closed by a ribbon to form a mold with movable walls.
  • the preform leaving the casting machine is first brought in a horizontal direction to be threaded between the cylinders of a straightener which gives it a suitable straightness, then it engages in the device responsible for sharing it in ingots.
  • This device is fixed by a mobile carriage which includes means for making it integral with the blank.
  • the blank drives the carriage with it, which allows the device to move synchronously with the blank and to exercise its sharing action on a determined section of the latter. .
  • the blank is first of all clamped progressively on two opposite longitudinal side faces using two jaws connected to the carriage so as to form imprints in line with these jaws and to develop on at at least one of the other two faces, at least one boss.
  • imprints which extend over the entire height of the blank are preferably symmetrical with respect to a vertical plane passing through the axis of the blank and they more or less follow the slope of the lateral faces.
  • the depth of these imprints can vary depending on the nature of the product or the shape of the blank.
  • the bosses which develop on the lower and / or upper face of the blank are located in a transverse plane passing through the imprints and appear on a section in line with the imprints as two nipples separated by a hollow; these nipples dominate the plane of these faces with a height which can be of the order of 1/10 of the height of the blank and join this face according to a convex curve.
  • the blank is cut in a plane perpendicular or oblique to its axis, to the right of the imprints, that is to say so as to share the bosses by their median plane.
  • Each ingot thus obtained has, in the lengthwise direction, a projecting profile at each of its ends, which constitutes the means of making it self-locking in a conventional stacking system.
  • each ingot is taken up by a processing chain in which sheets are formed where one ingot out of two can be turned over in order to bring its lateral faces into close contact with the neighboring ingot; then, the different layers are superimposed successively in the long direction and in the cross direction so as to constitute stacks.
  • the present invention also relates to a device making it possible to implement the method described above.
  • This device is characterized in that it comprises, connected to a mobile carriage, two jaws placed opposite two longitudinal lateral faces of the blank and intended, on the one hand to form imprints in line with these jaws, these- ci each comprising an edge extending over the entire height of the blank and on the other hand to develop at least one boss on at least one of the two other lateral faces, the device further comprising a knife responsible for shearing l roughing on at least part of its section in line with the impressions and the boss.
  • These jaws are schematically made up of a right prism of triangular section surmounted by a trihedron whose base has the same section as the prism. They are in relation to the lateral uprights of the carriage by one of their faces while the other two free faces intersect along an edge contained in a vertical plane perpendicular or oblique to the axis of movement of the blank.
  • each jaw In general, the height of each jaw is close to the height of the blank so that the impression is made from top to bottom of the lateral surfaces. Associated with these jaws, there is a knife fixed on the carriage and whose cutting edge is placed in line with the edges of the jaws. At rest, the edge of the knife is placed slightly behind the roughing pass line.
  • the movements of the carriage, the jaws and the knife are automatically controlled according to a sequence comprising the following steps: the carriage being in the rest position, the blank pushed by the straightener runs between the elements of the device.
  • the carriage is made integral with the blank by any means and is driven at the same speed as the draft.
  • This movement of joining causes the jaws to come into operation which come to be applied on the lateral faces of the blank to sink gradually and mark these faces with their imprint.
  • the jaws are quickly withdrawn while the knife gradually shears the blank over at least part of its section. Then, the knife is quickly withdrawn, the carriage is detached from the blank, animated by a rapid movement of translation in the opposite direction to that of the blank over a distance of the order of that of the length of the ingot and the solidarity is established again for a new cut.
  • the present invention finds its application in particular in the aluminum industry, in all cases where it is sought, starting from a continuously cast product, to obtain ingots having a constant section, a known length and suitable for a self-locking stacking.
