Definitions

  • the invention relates to a device for horizontal spray compacting of rotationally symmetrical products according to the preamble of claim 1.
  • Devices for spray compacting are known, for example from EP-A-02 25 732 a horizontal spray system can be found, the material being held by bearings which can be moved or adjusted radially with respect to this. Deviating from this, it is also known to provide shape-forming walls from EP-A-01 88 994 which are mounted in a cage which in turn is arranged in a housing so as to be rotatable and longitudinally movable. This arrangement eliminates the need for special supports for the block produced by spray compacting.
  • the invention is based on the object of designing the device mentioned at the outset in such a way that rotationally symmetrical products, in particular round billets, can be produced, with both a defined position being maintained during the spraying process and reliable longitudinal and rotary movement being possible.
  • the device has a spray chamber 9, which is chamfered on the spray side for receiving the spray nozzle 10, which sprays approximately at an angle of 35 degrees to the horizontal. Details of this nozzle arrangement and the metal feed are not shown here.
  • a transport device 7 is provided which can be approached to the stick by means of levers or a hydraulic system 8 and which makes it possible to remove the finished stick 5 from the spray chamber.
  • Holders 1 and one or more support devices 6 are provided in order to keep the start-up head or the stick already formed defined, but also to rotate and to remove it from the nozzle arrangement 10 in the longitudinal movement during the spraying process.
  • These holders 1 are on coaxial ring gears 3 arranged, which surround the start head or stick, namely, they are pivotally arranged there, so that a radial adjustment to the starting head or stick 5 is possible by means of cylinders. These are indicated in Figure 3.
  • the toothed rings 3 can rotate with the holders 1 arranged thereon around the starting head or stick 5, and common pinions 2 are provided for this purpose.
  • Two such holders are provided one behind the other, as can be seen in FIG. Both are constructed identically.
  • Servo cylinders 4 are arranged on the sprockets or holders, which are supported on one side of the spray chamber and with the aid of which the respective holders can be moved forwards or backwards, that is to say in the longitudinal direction in the direction of the spray nozzle 10 or away from it.
  • the holder itself can be of a similar design, so that radial positioning on the stick 5 is also possible.
  • the start-up head is first held in a defined position by the holders 1 in relation to the nozzle, so that the material first hits it, and then there is a continuous longitudinal movement and rotation of this start-up head away from the nozzle arrangement, so that gradually, as is the case results from Figure 2, a round billet is formed.
  • the holders 1 alternately come into action, ie a holder arrangement with the individual holders offset in the circumference holds the strand and is supported by the servo cylinder 4 moved in the longitudinal direction, at the same time rotating through the pinion gear arrangement 2/3.
  • the other holder arrangement is meanwhile moved back to the front starting position, so that when the other holding arrangement is in its rear position, it can continue to pull out the circular stick with the rotation while the other holding device is moved back to the front position.
  • the support device 6 is only clamped on the round billet to hold it, but does not have its own drive, ie the movement of the support device in the longitudinal direction takes place through the Clubs, and this also applies to the rotary movement.
  • a cable 11 can be provided in the upper part of the spray chamber.
