  • the present invention has for its object a process and apparatus for the manufacture of splined ingots which consists in stamping a malleable metal blank.
  • the said blank- which can be produced by molding in flat-bottom ingot molds-is produced by the continuous casting of the metal, according to a technique known per se, in a rotating wheel provided with a peripheral groove, to which is applied a band (belt) which covers the groove.
  • the metal blank while in a still malleable form, is then stamped, for example, by means of a mechanical 3,066,4dl Patented Dec. 4, i962 ice press; there are thus indented in said blank regularly spaced splines which are obtained by the action of a die presenting similarly spaced indentations which are pressed into the blank.
  • the stamping rate is synchronized with the speed of the continuous casting of the metal, and the speed at which the metallic blank is introduced under the stamping press.
  • the said press is provided with any device, such as for example, an ejector, enabling the immediate separation of the die from the blank following the stamping operation, in order to prevent the blank from being pulled out by the die.
  • any device such as for example, an ejector, enabling the immediate separation of the die from the blank following the stamping operation, in order to prevent the blank from being pulled out by the die.
  • the blank thus stamped is then automatically cut, by means of any device known per so, into units of predetermined length, dependent upon the subsequent use of the splined ingots produced according to the present invention; thus, one can directly obtain ingots of a length of the order of several tens centimeters, for example, of 370 min, 740 mm., 1110 mm., or of any length whatever.
  • FIGURES 5 and 6 represent, in front view and in section, a form of splined ingot obtained according to the present process from a blank having a trapezoidal section.
  • the present process is applied to the metallurgy of light metals, such as aluminum and aluminum alloys, use being made of the apparatus represented in FIGURE 7.
  • the reference number 1 generally designates any suitable continuous casting apparatus-illustrated in schematic formfor producing from molten metal a blank 2 of, say, trapezoidal section.
  • a continuons solid blank can be obtained by means of a rotating wheel 1' provided with a smooth trapezoidal shaped peripheral groove 1 which is covered by a movable endless band 1
  • Molten metal is supplied by any suitable means known in the art-not shown-between the periphery of the rotating wheel 1' and the travelling band 1
  • the formed blank 2 is conveyed and guided by means of a set of rolls 3 and introduced under a mechanical stamping press shown schematically at 4, equipped with a die 5 having the form of a comb; this die strikes the blank at each blow of the press, impressing deeply (engraving) the design of its teeth in the blank.
  • an automatic shears 7 which cuts the pressed blanks into units of predetermined length; the splined ingots obtained in this manner are collected at 8'.
  • the rate of press strikes and of cutting by the shears are synchronized as a function of the continuous casting speed of the molten metal, that is, of the forward speed of the blank.
  • Such synchronization can be effected by any suitable means--as by an apparatus (represented in FIGS. 9 and 10) comprising a connecting-rod l2 and a crank 12 keyed on the shaft of the stamping-press 4.
  • Connecting-rod 12 imparts alternating (up-and-down) motion to a lever 14 which drives, by means of a pawl and ratchet wheel system 15 and 16 (or a free-wheel system),
  • the present invention also has for its object as novel industrial products, the splined ingots such as are illustrated in FIGURES 5 and 6.
  • Such ingots are commonly employedamong other usesin steel works as deoxidizing products; they present the great advantage of being easily fragmented into units of variable .and, if desired, small lengths and widths.
  • Continuous process of forming splined ingots comprising the steps of: continuously molding a blank of indefinite length of solid cross section from molten metal; conveying the molded blank while in a malleable state to a stamping station; stamping the desired indentations into the blank by a vertically moving stamping means, preventing the stamped blank from traveling upwardly with the stamping means following a stamping operation, cutting the stamped blank into units of predetermined length and synchronizing the conveying and cutting operations with the stamping operations.
  • Apparatus for the manufacture of splined ingots comprising, in combination: means for continuously casting a metal blank of indefinite length; a stamping press comprising a movable die; means for conveying the formed blank to the stamping press, said press including means for preventing a stamped blank from being pulled along by the movable die following a stamping operation, and means synchronized with the stamping press for cutting the stamped blank into units of predetermined length.
