Definitions

  • the present invention relates to an ultrasonic transducer comprising an ultrasonic horn and a magnetostrictive driver, wherein the driver is connected to a contact surface of the ultrasonic horn facing it, and a method for producing a permanent connection between the ultrasonic horn and the driver of such an ultrasonic transducer.
  • magnetostrictive ultrasonic transducers A problem in the design of magnetostrictive ultrasonic transducers is that the magnetostrictive material must be suitably connected to the ultrasonic horn, wherein this connection is realized in the prior art usually by means of a soldering process, in particular a brazing process.
  • Generic magnetostrictive ultrasonic transducers of the aforementioned type are for example from the WO 2004/105085 A1 and the WO 2006/055368 A2 known.
  • the driver consists of a plurality of plates of magnetostrictive material (hereinafter referred to as magnetic plates) soldered in recesses of the ultrasonic horn or on a surface of the ultrasonic horn by means of a brazing process.
  • a suitable geometry of the magnetic plates allows the loading of the plates with an alternating magnetic field.
  • the ultrasonic transducers described in the above-mentioned publications e.g. central opening in the magnetic disks and a suitable coil arrangement is provided, with which the two legs delimiting the opening of the magnetic disks can be excited with appropriate energization of the coil using the effect of magnetostriction to a vibration in the ultrasonic frequency range. This vibration is then transmitted from the magnetic plates to the ultrasonic horn and passed within the ultrasonic horn on to its oscillating head.
  • the above-mentioned disadvantages of magnetostrictive ultrasonic transducers also occur in this prior art.
  • DD 59 963 A a method for connecting electromechanical transducers with coupling links and tools of ultrasonic transmitters is known in which the laminated core of a magnetostrictive transducer to achieve a low-loss coupling by electron beam welding is connected to a flat end face of the ultrasound generator. It requires a high energy for the electron beam to weld the laminated core in the entire end face with this. On the other hand, this connection technique proves to be not very stable, since the laminated core is held exclusively on the flat surface.
  • EP 0 468 125 A2 an ultrasonic horn, in which two adjoining sections are connected by means of electron beam or laser beam welding.
  • the object of the present invention consequently to a method for producing a permanent connection between the ultrasonic horn and magnetostrictive driver of such an ultrasonic transducer.

  • the electron beam or laser beam is aligned or guided so that it enters through the lateral boundary wall of the socket-like elevation in the massively configured ultrasonic horn at the level of the contact surface and parallel thereto.
  • the method of electron beam welding or laser beam welding used according to the invention in the region of the contact surface opens up the possibility that the ultrasonic horn, the contact surface of the ultrasonic horn and / or the magnetostrictive material of the driver prior to manufacture the weld joint according to the invention can be subjected to a separate heat treatment, without the associated advantages in the subsequent production of a permanent Connection between driver and ultrasonic horn subsequently destroyed again or adversely affected.
  • the known from the prior art method of brazing is associated with the disadvantage that the brazing required temperatures in the range of about 750 ° C before a fabricated by complex heat treatment material structure of the ultrasonic horn and / or the magnetostrictive material of the driver disadvantageous again change, so that the benefits of a previous heat treatment of said elements in the finished ultrasonic transducer did not fully come to fruition.
  • the temperature of the ultrasonic transducer - even in comparison to other welding methods - is lower and limited to a much smaller range.

This has a positive effect on the fatigue strength of an ultrasonic transducer according to the invention and in particular also leads to a higher load capacity of the connection point between the driver and the ultrasonic horn. In addition to the possibility of use under higher loads, this also opens up greater flexibility with regard to the exact arrangement of the connection point, taking into account the acoustic vibration conditions over the length of the ultrasonic transducer.
  • Another aspect of the present invention which did not receive sufficient consideration in the prior art, is again based on the fact that during brazing or brazing a large area around the actual connection point is at a high temperature (in brazing about 750 ° C.). which is not the case with electron beam welding or laser beam welding.
  • the magnetostrictive material of the driver of an ultrasonic transducer according to the invention is preferably provided with an insulating layer, which is often damaged by exposure to the temperatures required for soldering over a large area, which may, for example, lead to short circuits between adjacent elements of the driver.
  • the height of the - required for connecting the driver with the ultrasonic horn and along the contact surface transversely guided - weld in an advantageous Sense is limited to a height of up to about 1-2 mm, which is associated with significantly lower damage of insulating layers on the magnetostrictive material of the driver.
  • the contact surface, along which the welded connection is made between the edge of the driver and the contact surface of the ultrasonic horn is formed by the bottom of at least one receiving pocket which receives the ultrasonic horn side end of the driver.
  • the term receiving pocket is thereby advantageously understood to mean a cutout in the side of the ultrasonic horn facing the driver, which contour matches the contour of the driver or the magnetostrictive elements.
  • sufficiently large seam depths for the weld to be produced can be produced for the present purpose so that the electron or laser beam used to produce the welded joint can be guided and adjusted in such a way that it passes through an edge region of the solid ultrasonic horn Required welded joint in the region of the serving as a contact surface bottom of a receiving pocket - without that in areas above the actual weld a short circuit of adjacent magnetostrictive elements or in large areas around the actual junction or area around an undesirable change in the material structure is caused.

  • the at least one receiving pocket is formed in a base-like elevation of the driver's facing end of the ultrasonic horn.
  • a pedestal-like elevation it may in particular also be realized in that a region surrounding the receiving pockets of the ultrasonic horn has been taken back by cutting.

  • all types of magnetostrictive materials can be used as the material for the driver, it being apparent that those with a high magnetostriction are to be preferred. These include e.g. FeCo alloys or terbium-containing alloys, e.g. the alloy families known under the generic names Hiperco, Terfenol and Gerfenol.
  • the magnetostrictive and vibratable with a suitable coil assembly driver of an ultrasonic transducer according to the invention in a variety of geometries of one or more magnetostrictive elements can be realized - as long as it is suitable for ultrasonic conversion and at least within the scope of the invention edge or front side with a facing him contact surface of the ultrasonic horn is welded.

Even in the region of the particular loads subjected contact surface (s) and / or facing away from the driver and also highly loaded oscillating head proves to be advantageous. Even in the case of the driver can be used in an advantageous manner to a previous heat treatment, since in particular the magnetostrictive properties of the material used can be optimized.
