Definitions

  • the invention relates to a method for descaling round steel bars, in particular hot-rolled steel bars, in which a group of steel bars is lifted together, shifted horizontally while maintaining their mutual relative position, placed on a roller table and conveyed by means of the roller table through a descaling device; the invention further relates to a plant for performing the method.
  • a descaling device with rod material in which several devices, each with a carriage, are provided parallel to a roller table of the descaling device, all of the carriages being movable together horizontally.
  • the ready material is grasped with the help of this device, raised a little and, after a horizontal displacement by means of the trolleys, placed on the roller table of the descaling device.
  • the roller table then conveys the material through the blasting chamber of the descaling device.
  • the main disadvantage of this procedure is that the feed of the steel bars depends on the working speed of the descaling device and that a continuously adjustable transverse distance between the steel bars cannot be provided.
  • the object of the invention is to avoid the disadvantages of the prior art and to provide a method and a system for carrying out the same, with which a flawless supply of steel rods with an infinitely variable transverse spacing of the rods from the feed device operating at a relatively high speed is achieved in a simple manner to the relatively slow descaling device.
  • the method according to the invention has the features that the steel bars are in succession while maintaining a selectable transverse distance be dropped onto a feed device that moves continuously in the transverse direction of the bar and the set of bars is lifted from these continuously moving steel bars and after the horizontal displacement onto the roller table in the longitudinal direction of the bar while keeping the predetermined relative position of the bars, the descaling device in which the bars are transferred in the descaled substantially over their entire scope.
  • the rods are preferably aligned in the transverse direction of the rod and preferably also in the longitudinal direction of the rod after they have been applied to the feed device.
  • a system designed according to the invention for carrying out the method with a feed device for round steel bars and a device connected downstream for feeding the bars with a mutual transverse spacing, with transport combs, which are arranged on a transport carriage in a height-adjustable manner for lifting coulters from the feed device, with one device for receiving the rods from the transport combs and for transferring the rods in the longitudinal direction to a descaling device, and with a control device for the feed device, the transport combs and the transfer device is characterized in that above the feed device, as is known per se, has a rod end at its end from the laterally arranged feed device, the bar ejection device is arranged in such a way that the bar ejection device has at least one pivotable discharge chute for receiving one bar and has a discharge channel open to the feed device, the pivoting movement of the discharge channel being able to be matched to the conveying movement of the feed device by means of the control device such that the rods can be deposited on the feed device with a selectable trans
  • the transfer device is preferably designed as a roller table with a plurality of drivable rollers which, as is known per se, can be pushed through by the transport combs for transferring the rods.
  • the guide device is formed by a lower roller with a roughened, preferably grooved surface and an upper pressure roller which can be adjusted against the lower roller.
  • the discharge channel of the discharge device ends near the feed device and can be closed in the conveying direction of the feed device by a height-adjustable stop that can be actuated by means of a positioning device.
  • an end position monitor controlling the lifting movement of the transport combs is advantageously provided at the end of the feed device facing away from the discharge channel.
  • the supply device can be preceded by a supply device with two magazines for pre-cut steel bars and can be moved in the transverse direction of the bar, the feed device preferably containing a cutting device.
  • a supply device with at least one round steel material supply drum with a subsequent straightening device can be connected upstream of the feed device, the feed device containing a cutting device.
  • a rod S in its longitudinal direction P2 is via a feed device 3, which is provided with feed rollers (not shown), a length measuring device and a pair of scissors, is fed to a discharge device 4 with a discharge channel K which is open at the bottom.
  • the discharge device 4 as will be described in more detail later with reference to FIG. 2, the bars S fall individually onto a horizontally arranged feed device 5 which consists of a plurality of parallel conveyor belts 6 arranged at a mutual distance from one another.
  • the conveyor belts 6 are guided by a drive roller 7 which is common to all conveyor belts and driven in the direction of the arrow P 1 and by a deflection roller 8 per conveyor belt 6.
  • a corresponding control command is given to the transport combs 10 so that they are lifted simultaneously and in parallel in the direction of the arrow P5 and the rods S lift off the conveyor belts 6.
  • the length of the transport combs 10 is selected so that all the bars S to be processed are securely gripped.
  • the surfaces 10 'of the transport combs 10 are grooved to prevent slipping of the bars S in the transverse direction during the movements of the transport combs 10.
  • the roller table 13 consists of several mutually separate rollers 12, which are mounted on a common frame 16, and are driven individually or in groups via driven connecting chains 17.
  • One of the descaling device 14 adjacent roller 18 of the roller table 13 has a grooved surface 18 '.
  • the transport carriage 9 moves with the transport combs 10 in the lowered position from the position 103 in the direction of the arrow P9 into the starting position 101 (FIG. 2).
  • the discharge device 4 has two discharge channels 20, each of which receives a rod.
  • each discharge channel 20 By swiveling each discharge channel 20 according to the double arrow P10 the rod S passes through the discharge channel K to the feed device 5 and is horizontally conveyed away from the discharge channel K in the direction of the arrow P3.
  • the ejection movement of the rod S in the direction of the arrow P11 is preferably done by gravity, but can also be accelerated by additional, not shown deflection fingers.
  • the discharge channel K ends as close as possible to the conveyor belts 6 of the feed device 5 in order to position the falling rods as precisely as possible on the conveyor belts 6.
  • a positioning device 21 with a plurality of stop bolts 22 which can be adjusted in accordance with the double arrow P 12, which are each located between the conveyor belts 6 and extend the discharge channel K downwards on the outlet side.
  • the pivoting movement of the discharge chute 20 is matched to the conveying speed of the conveyor belts 6 of the feed device 5 in such a way that the bars S approximately fall onto the conveyor belts 6 with the transverse distance desired for the descaling device 14. If two discharge channels 20 are used, these are preferably actuated alternately. Sloping bars are moved by means of the positioning device 21 while the conveyor belt is running aligned.
  • control device mentioned also controls all controllable devices and their movements, such as the displacement of the supply device 1, the feed device 3, the discharge device 4, the feed device 5, the method of the transport carriage 9, the vertical displacement of the transport combs 10, the transfer roller table 13, the conveyor device 15 , and the positioning device 21 with the stop pin 22nd
  • Fig. 1 it is possible within the scope of the invention to provide several storage magazines 1 ', 1 ⁇ , one storage magazine 1' being in the transfer position to the feed device 3, while the other storage magazine 1 ⁇ is ready for loading with rods.
  • the rod material can be fed directly from supply drums or reels into the supply device 3 via a straightening system.
