Definitions

  • the invention relates to a device for guiding rod-shaped or wire-shaped workpieces in a continuous centrifugal jet machine, as characterized in the preamble of claim 1.
  • the object of the present invention is to provide a device of the type mentioned, which, while avoiding the disadvantages mentioned above, ensures an adaptation of the guides for workpieces with different cross-sectional dimensions without having to replace them, this adaptation also being able to be incorporated into an automatic control of the centrifugal jet machine and a changeover should also be possible without machine downtime.
  • FIG. 1 shows a schematic illustration of a continuous centrifugal blasting machine for rod-shaped or wire-shaped workpieces 4 with a steel chamber 1, which has three blasting areas 2a, 2b, 2c. In each blasting area 2a, 2b, 2c, centrifugal wheels 3 with different blasting directions are arranged for all-round blasting treatment of the workpieces 4.
  • a guide device 5 for the workpieces 4 is arranged on the inlet side and the outlet side of the blasting chamber 1 and between the blasting areas 2a and 2b or 2b and 2c.
  • a seal is provided in front of and behind the corresponding guide device 5 in the direction of passage 6
  • Direction 7 is provided for sealing the blasting chamber 1 against blasting agent escaping.
  • the sealing devices can have brushes or sleeves, plates, flaps or similar organs made of rubber or similarly behaving materials, so-called labyrinth seals are also known.
  • Roller tables 8 for the supply and removal of the workpieces are arranged on both sides of the blasting chamber.
  • support elements 9a, 9b, 9c are arranged in the blasting areas 2a, 2b, 2c on the opposite side of the workpiece 4 from the blasting treatment, which are intended to prevent the workpieces 4 from bending too strongly during the blasting treatment.
  • FIGS. 2 and 3 show one of several guide devices 5 arranged in the blasting chamber 1 in an embodiment variant, which is particularly suitable for workpieces 4 which are square and round in cross-section or also polygonal or similarly shaped.
  • the guide device 5 has a lower guide part 11a fixedly attached to a carrier 10 of the blasting chamber 1 and an upper movable guide part 11b arranged offset therefrom in the direction of passage 6.
  • Each guide part 11a, 11b has two guide surfaces 20 which are arranged parallel to the direction of passage 6 and in a V-shape and which together form a guide bushing which is square in cross section.
  • the side length of the square or the enveloping circle diameter can be changed by moving the upper guide part 11b by the displacement path S in order to adapt it to different cross-sectional dimensions of the workpieces 4 passing through.
  • Each guide part 11a, 11b has, on the inlet side 21, which is determined by the direction of passage 6, inclined deflection surfaces 22 extending to the guide surfaces 20 thereof.
  • the Guide part 11b is fastened to a guide bar 12 which, in the vertical direction in the blasting chamber 1, is operatively connected outside the blasting chamber to an adjusting device 13.
  • the adjusting device 13 has a pivotably mounted shaft 14 which is arranged along the direction of passage 6 and to which a pivot lever 15 is fastened for each guide device 5 and which is connected to the guide bar 12 via a slot 16 and a pin 17.
  • the shaft 14 is connected via a lever 19 to an electric, hydraulic or pneumatic actuator 18.
  • the actuator 18 can be operatively connected to a program control of the continuous centrifugal jet machine, so that an automatic adjustment of the guide devices is possible depending on the workpieces to be treated or their cross-sectional dimensions. It is also possible to adjust each individual guide device by hand using a linkage or by means of a remote-controlled actuator.
  • the two guide parts 11a, 11b of each guide device 5 can be adjusted simultaneously from and to one another symmetrically, preferably in the horizontal direction by the adjustment path S.
  • the center of the axes of the continuous workpieces always remain in the same position, so that there is no change in distance to the other components of the centrifugal jet machine.
  • the design of the two guide parts 11a, 11b corresponds to the guide parts shown in FIGS. 2 and 3.
  • FIGS. 6 and 7 show an embodiment variant of a guide device 5 with three guide parts 23a, 23b, 23c, which can be adjusted simultaneously with an adjustment path S. which are arranged triangular to each other.
  • Guide part 23a, 23b, 23c has a straight guide surface 20 with an adjoining deflecting surface 22.
  • the guiding surfaces and the deflecting surfaces can also be arched, concave or convex. It is also possible to adjust the support elements together with the guide devices.
  • the guide parts 11 and 23 are each easily replaceable and made as castings from a manganese-containing chilled cast iron.
