Definitions

  • the invention relates to a centrifugal blasting machine for continuous blasting treatment of wire and rod-shaped workpieces, as characterized in the preamble of claim 1.
  • a centrifugal blasting machine of the type mentioned has become known from DE-C3-1815187, wherein each pair of jet guide plates allocated to a centrifugal wheel can be adjusted manually to the respective workpiece dimension by means of an adjusting device having a threaded spindle.
  • DE-C2-1954271 shows a further development of the previously mentioned centrifugal blasting machine, in which all pairs of jet guide plates can be adjusted manually by means of an adjusting device.
  • the jet guide plates For workpieces with different cross-sectional dimensions or diameters, the jet guide plates must always be based on a scale readjusted, which is very time-consuming and incorrect settings can damage the machine or workpieces.
  • the object of the present invention is to provide a centrifugal blasting machine of the type mentioned in the introduction, in which an automatic adjustment of the jet guide plates, which is dependent on the workpiece cross section, is ensured when changing the workpiece dimensions.
  • the beam guide and guide plates are automatically adjusted depending on the diameter of the workpieces to be treated, which means that there are no downtimes and incorrect settings are avoided even with frequent workpiece changes.
  • an adjustment device arranged on a centrifugal jet machine for the common adjustment of the jet guide and guide plates assigned in pairs to the centrifugal wheel units is shown in simplified form and is described below:
  • shafts 4a to 4f which are axially parallel to the conveying direction of the wire-shaped or rod-shaped workpiece 3 are rotatably mounted on the end walls of the blasting chamber 1 and with which jet guide and guide plates 5a to 5f can be adjustably connected with the aid of clamping pieces 6 are.
  • the jet guide and guide plates 5a to 5f are arranged in relation to the centrifugal wheel units in accordance with the centrifugal jet machine described in the patent DE-C3-1815187 mentioned at the outset.
  • An adjusting device 7 is arranged on the input or output side of the blasting chamber 1 such that it is located outside the blasting area of the centrifugal wheel units.
  • the adjusting device 7 has chain wheels 8a to 8f connected to the shafts 4a to 4f in a manner fixed against relative rotation.
  • a chain 9 connecting the sprockets 8a to 8f is alternately stretched on the side facing the workpiece 3 and on the other side on the side facing away from the workpiece over the successive sprockets 8a to 8f, so that when one of the shafts, e.g. the shaft 4a with the sprocket 8a, e.g. clockwise, the sprockets 8c and 8e are rotated in the same direction with 8a and the sprockets 8b, 8d and 8f in opposite directions.
  • a double-armed lever 10 is connected in a rotationally fixed manner to the shaft 4a, an adjusting drive 11 engages on its outer lever arm 10a, and a scanning device 12 is arranged on the lever arm 10b reaching up to the workpiece 3, which scans the position of the upper workpiece circumferential surface and thus its cross-sectional dimension .
  • the adjustment drive 11 is preferably a by means of a pressure medium such as Piston-cylinder unit 13 which can be acted upon by compressed air and which has an integrated locking or clamping device 14 for clamping the piston rod 15.
  • a pressure medium such as Piston-cylinder unit 13 which can be acted upon by compressed air and which has an integrated locking or clamping device 14 for clamping the piston rod 15.
  • the scanning device 12 is an electrical switch, preferably an inductive proximity switch, which is connected via a control device 16 and a solenoid valve 17 the piston-cylinder unit 13 is operatively connected.
  • the beam guide and guide plates occupying a position such that the plates 5a and 5b, 5c and 5d and 5e and 5f, which belong together in pairs take the largest opening angle to each other.
  • a signal “workpiece present” automatically comes into the control device 16 via a line 18, whereby the piston rod is moved upwards according to arrow 19.
  • the scanner 12 is brought up to the workpiece 3 by the double-armed lever 10 until, at a set distance from it, the piston rod movement is stopped via the control device 16 and the solenoid valve 17, the piston rod 15 being held clamped in this position at the same time.
  • the scanning device and the beam guide plates are always first moved back to the outer starting position, and the new setting is then carried out as described above.
  • the adjustment drive can also be an electro-mechanical drive such as be an electric motor with a threaded spindle, in which case the solenoid valve on the control device is then omitted.
  • a e.g. support roller which can be pressed on by means of springs.
