Definitions

  • the present invention relates to an apparatus for transmitting ultrasound.
  • Such devices are known in principle from the prior art and are used, inter alia, for amplitude transformation or amplitude amplification of the ultrasonic vibrations transmitted from a converter to a sonotrode.
  • the device has a curved oscillating body with a coupling surface provided at one end for coupling a converter, the oscillating body being curved in particular in the form of a U, an S or a J. is trained. Furthermore, the oscillating body has at least one indentation running over the circumference of the oscillating body between the coupling surface and the end opposite it.
  • the oscillating body apart from the retraction, can have an essentially constant cross-sectional shape. This means that the oscillating body is designed to be uniform over its essential course and, apart from the indentation or a base for coupling surfaces, has the same cross-sectional shape.
  • the oscillating body can have quarter-circular sections on both sides of the indentation, so that with each section a deflection of 90 ° in the same plane or in different planes is achieved.
  • quarter-circular sections between which there is a recess has achieved good results in tests.
  • the retraction can be curved in cross section, for example as a circumferential annular groove.
  • a further coupling surface for a sonotrode can be provided at the end opposite the coupling surface.
  • the vibrating body can be equipped with different sonotrodes and converters thanks to a modular structure.
  • a sonotrode can be integrally formed on the end opposite the coupling surface.
  • the oscillating body can have a rectangular or square cross section. In contrast to other or asymmetrical cross-sections, a particularly uniform vibration behavior can be achieved in this way.
  • the vibrating body is constructed in several parts.
  • the oscillating body can be designed to be curved in any planes, which can be advantageous in complex installation situations. However, it can also be advantageous to design the oscillating body to be curved only within one plane. Another advantageous embodiment can be formed in that the oscillating body is curved in two planes extending at right angles to one another.
  • Fig. 1 shows a first device for transmitting ultrasound to a sonotrode, which shows a curved oscillating body 10 with a coupling surface 14 formed at one end 12 for coupling a converter.
  • the oscillating body 10 is designed in the form of an (inverted) U and has a further coupling surface 18 for a sonotrode at the end 16 opposite the coupling surface 14.
  • Both coupling surfaces 14 and 18 are designed in the shape of a circular ring and are molded onto the oscillating body 10 via a base 20 or 22, respectively.
  • an indentation 24 is provided which runs over the circumference of the oscillating body and divides the oscillating body into two quarter-circle sections A and B.
  • the oscillating body 10 has a constant, approximately rectangular cross-sectional shape.
  • the indentation 24 has a concave curvature in cross section, so that the indentation 24 forms a total of four grooves running at right angles to one another on the outer circumference of the oscillating body 10.
  • the vibrating body 10 of Fig. 1 made in one piece from metal is made, has a constant radius of curvature on both sides of the indentation 24, so that the overall shape of a U results.
  • Fig. 2 shows a further embodiment of an oscillating body 30, the same reference numerals being used for the same components.
  • the vibrating body 30 of Fig. 2 differs from the vibrating body 10 of Fig. 1 solely in the fact that the two curved sections A and B are oriented on both sides of the indentation 24 in such a way that the shape of an S (or approximately a Z) results for the oscillating body.
  • the oscillating body has a constant radius of curvature on both sides of the indentation 24.
  • the curvature of the oscillating body has a point of inflection in its center, ie in the area of the indentation 24.
  • the in Fig. 3 The vibrating body 40 shown corresponds in its basic structure to the vibrating body 10 of FIG Fig. 1 .
  • the oscillating body 40 has no base and no further coupling surface at its end 16 opposite the coupling surface 14. Rather, a sonotrode S is formed in one piece on the end 16, with a further indentation 44 being provided between the sonotrode S and the section A of the oscillating body 40, which is designed in the same way as the indentation 24.
  • Fig. 4 shows a further embodiment of an oscillating body 50, the basic structure of which is the oscillating body 30 of Fig. 2 corresponds, but the two sections A and B, which are each formed in the shape of a quarter circle, compared to the embodiment of FIG Fig. 2 are rotated by 90 °.
  • the oscillating body 50 is curved in two planes standing at right angles to one another, ie the two coupling surfaces 14 and 18 do not run in the same plane Fig. 1 ) and also not within two parallel planes ( Fig. 2 ). Rather, in the oscillating body 50, the two coupling surfaces 14 and 18 run in two planes running at right angles to one another.
  • the confiscation 24 is in the embodiment of FIG Fig. 4 also curved in cross-section.
