Definitions

  • the invention relates to a device for inserting rolled steel profiles collected in layers behind cooling beds into a cold shear or straightening machine, in which the profile layers transported on a roller table in front of the straightening machine or scissors are held by a profiled hold-down roller, movable from a hanging in the longitudinal direction of the profile above the roller table, as Lifting magnet with profile strips designed holding device are taken over and transported synchronously to the transport speed of the roller table to the driver of the cold shears or leveling machine.
  • the threading device of the generic type is not used in connection with the upstream devices for holding the bars during the entire cooling process, but is subsequently introduced, for example, into existing finishing systems, then there is still the problem of placing odd bar packages in such a way that the solenoids take over properly is possible and the insertion into the scissors or the straightening machine is guaranteed. It must also be ensured that when the bars are transported, the speed of the lifting magnet holding the bar ends and the roller table are matched to one another in such a way that the bars are not accelerated or decelerated with respect to the magnet by friction on the roller table rollers. This would cause the bars to shift or fall apart.
  • the object of the present invention is. to create a device for inserting the rolled steel profiles in cold shears or straightening machines, which can be retrofitted into existing systems and which ensures a safe guidance of the steel bar layers in the shears and straightening machine.
  • the hold-down roller and the holding device are arranged on a common carriage, that the lifting magnet can be displaced relative to the holding device by a limited path parallel to the transport path of the carriage and is provided with a displacement measuring device which is controlled by a computer Depends on the measured distance a signal to the drive of the car for adaptation and the car speed to the material speed.
  • the lifting magnet is brought into a shifting central position relative to the holding device, which can be accomplished, for example, by springs.
  • the displaceability of the lifting magnet reliably prevents the bars from tearing off or slipping on the magnet.
  • the carriage 3 After placing a collected rolled steel profile layer 1 on the straightening or cutting roller table 2, the carriage 3, on which both the lifting magnet 6 on the holding device 13 and the profiled hold-down roller 5 are arranged, moves from its waiting position over the rod heads 4 into the cooling bed area and behind the beginning of the curvature of the rod. There, the profiled roller 5 is lowered onto the rolled steel profiles 1 and the carriage 3 moves in the direction of the start of the bar 4. Elevated or horizontally curved bars are thus brought to the specified distance and pressed down at the same time.
  • the profiled roller 5 is then moved into the upper position and then the magnet lifts the rod heads from the roller table by about 10 to 20 mm.
  • the drive 9 of the carriage 3 is switched on at the same time.
  • the acceleration of the carriage 3 is specified electrically as the theoretical material acceleration through the roller table 2 is expected. Acceleration and deceleration are determined by the friction factor between the roll and the bar material.
  • the Madget 6 with the interchangeable profile strips is slidably arranged on the carriage 3 in and against the direction of transport on a track 14, so that in the event of speed differences, the travel drive of the carriage is constantly adapted to the material speed by means of an electrical path measuring device 10 (FIG. 3).
  • the electrical control is designed so that the magnet constantly strives for the center or zero position of the synchronization control. In the unloaded state, return springs 11 or cylinders ensure that the magnet is always in the zero position.
  • the carriage with the magnet 6 switched on introduces the rod heads 4 into the scissors 8 or a driver 12, releases the magnet 6 after transfer and moves back to its parking position in front of the cooling bed with the magnet raised.
