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 egg threading device of the generic type is not used in connection with the upstream devices for holding the rods during the entire cooling process, but is subsequently introduced, for example, into existing finishing systems, then there is still the problem of placing odd rod packages in such a way that they are properly taken over by the lifting magnet is possible and the introduction 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 relative 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 distance, 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 adjustment and the calf speed to the material speed.
  • the advantage of the proposal according to the invention can be seen in the fact that even asymmetrical profiles, such as angles. which are known to stand up at their ends after the cooling process (ski effect) by the profiled hold-down roller arranged on the carriage when the carriage is moved into the required position and that the hold-down roller can depress the profiles before the magnets are attached. Furthermore, it is ensured that the speed of the rod storage corresponds to the speed of the magnet arranged on the carriage or on the holding device. in that the magnet is designed to be displaceable on the holding device and the displacement path is used as a measure and signal for controlling the drive.
  • the lifting magnet after the bar magnet has been released by the lifting magnet, to bring the lifting magnet 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 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 simultaneously switched on.
  • 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 arranged on the carriage 3 so as to be displaceable 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.
