Definitions

  • Wood l OOOOQOOOOUQ QO GAGE FOR CONTROLLING LENGTH OF SEGMENTS CUT FROM A LONGER PIECE This invention relates to an improved gage for controlling the length of segments which a traveling cutoff machine cuts from a longer piece.
  • our gage is particularly useful as applied to a machine which cuts segments of a specified length from a much longer continuously cast steel product (slab or billet).
  • Theoriginal casting which may be several hundred feet long, is reheated immediately following the casting operation, and thence travels through .a series of roll stands. After emerging from the lastof these stands, the product is cut into shorter segments, for example 18 or 36 feet long.
  • the cutoff machine commonly includes a carriage equipped with either cutting torches or a circular saw. The carriage is clamped to the product and travels therewith as the torches or saw make their cut. Initially the carriage is stopped and its clamps are disengaged from the product while alength of product equal to the desired length of segment passes.
  • An object of our invention is to provide an improved gage which is of simplified construction, yet is accurate and reliable for use with pieces at a high temperature.
  • a further object is to provide an improved gage of the foregoing type which is readily adjustable for cutting segments of different lengths.
  • a more specific object is to provide an improved gage which comprises rather simply a spring-loaded drum, a cable wound on the drum and extending over the piece to a motordriven drum on the cutoff machine, a rod freely suspended from the cable into the path of the piece and suitable electric controls.
  • FIG. 1 is a diagrammatic side elevational view of a portion of a cutoff machine and adjacent parts equipped with our gage;
  • FIG. 2 is a wiring diagram of the electric circuit.
  • FIG. 1 shows the carriage of a traveling cutoff machine, which may be of either the torch type or the saw type.
  • An elongated piece P which may be at a high temperature and is to be cut into segments S of a specified shorter length, travels through the carriage from right to left.
  • the cutoff machine may be constructed and operate as shown and described in the aforementioned MeDermott or Krueger patents; hence we have not repeated the showing.
  • Conveyor rollers 12 support the piece P and segments S on the exit side of carriage 10.
  • a set of conventional power-driven pinch rolls I3 are journaled in a housing I4 and propel the segments as they leave thcrollers 12.
  • the top of the pinch roll housing 14 carries bearings 17 in which we journal a springloaded drum I8.
  • the exit side of the carriage 10 carries bearings 19in which we journal a drum 20 driven by a reversible electric motor 21.
  • Drum 18 has sufficient capacity that the entire cable can wind on it, and preferably drum 20 is of the same size.
  • We operate motor 21 toadjust the cable to a position such that the leading end of the'piece abuts the rod when the desired length of segment S has passed the carriage. Thereupon the cutoff machine starts its cut.
  • the spring-loaded drum 18 takes up the cable 22 while the carriage approaches the pinch rolls 13 during the cutting operation.
  • the carriage pulls the cable back when it returns to its starting position, so that rod 23 also returns'to its starting position. Since the rod is freely suspended, it does not interfere with movement of segments S as they pass on their way to the pinch rolls 13.
  • relay A is equipped with a suitable timer (not shown) to deenergize it automatically when the eutoff machine starts, and reset it automatically in time for the next operation. Meanwhile the cutoff machine makes its cut and the carriage returns to its starting position.
  • FIG. 2 shows our preferred circuit for motor 21.
  • the motor is equipped with a brake 28 which is applied or released automatically when the motor is deenergized or energized, as known in the art.
  • the motor also drives a Selsyn" transmitter 29 and a cam 30 for operating limit -switches 31 and 32 hereinafter described.
  • gage for controlling the segment length
  • said gage comprising a flexible cable, a first support for said cable mounted above said conveyor at a location spaced from said carriage, a second support for said cable mounted on said carriage, and a rod freely suspended from said cable into the path of the piece on said conveyor for contact by the leading end of the piece when a length thereof equal to the segment length passes said carriage, said first support including means for taking up said cable as said carriage approaches.
  • second support includes a drum journaled on said carriage and a reversible motor for driving said drum.
  • a combination as defined in claim 1 comprising in addition electric means connected to said rod and said conveyor for starting said machine automatically when the leading end of the piece abuts said rod.
  • said propelling means includes a set of power-driven pinch rolls and a housing in which said rolls are journaled
  • the means for taking up said cable includes a spring-loaded drum journaled on said housing
  • said second support includes a drum journaled on said carriage and a reversible motor for driving said second-named drum and thereby adjusting the position of said rod.
  • a combination as defined in claim 5 comprising in addition cam operated limit switches connected with said motor to prevent said rod from hitting either of the supports for said cable.
  • a combination as defined in claim 5 comprising in addition a limit switch operated by said rod as it approaches said housing to actuate said motor.
