Definitions

  • the invention relates to a hand tool for processing, in particular for cutting a process material using ultrasound energy and a device with at least one such knife.
  • a process material is also to be processed manually. For example, to inspect a product, cuts are made through a processed process good to determine the quality. In a shop, for example in a bakery or a butchery, a process good, such as bread, meat or cheese, but also manually very fine and precise cut can be what often fails with conventional knives, even if the process material is clamped.
  • the present invention is therefore based on the object to provide an improved hand tool, with which a process material can advantageously be processed manually using ultrasound energy, in particular cut or atomized.
  • the hand tool should be compact and easy to handle. Nevertheless, relatively large process material, in particular bread, meat, cheese and vegetables can be processed precisely and with little effort with the hand tool.
  • the hand tool should work efficiently, so that it can work with an external or a local power supply unit and has only a relatively low weight even in autonomous operation.
  • the ultrasound energy should be transferable to a sonotrode with virtually no losses. Furthermore, if necessary, sufficient ultrasonic energy is available, so that even mechanically solid process material can be processed. Furthermore, the hand tool should also be constructed stably, so that mechanically solid process material can be processed over a longer period of time without the occurrence of signs of wear.
  • the hand tool comprises a tool part, which is held in a preferably wooden-cylindrical housing body of a housing part and which comprises an ultrasound transducer provided with at least one piezo element, which serves to deliver ultrasound energy to a blade provided on the tool part.
  • a plurality of piezo elements separated by contact elements are provided, each having a transfer opening through which a transducer rod is passed, which is integrally or directly or indirectly connected to a coupling rod which is integrally connected to the blade and that one connected to the transducer rod Pressing element is provided, by means of which the piezo elements are pressed against a stop and mechanically coupled to the coupling rod.
  • the coupling rod and the transducer rod or the coupling rod and the connecting cylinder are welded together so that a virtually one-piece connection between the transducer rod and the coupling rod and optionally provided therebetween connecting pieces, such as the connecting cylinder and the connecting bolt results.
  • the transducer rod is aligned coaxially with the facing first part of the coupling rod, so that the provided with the ultrasonic transducer part of the tool part can be arranged with little space in a cylindrical housing body, which is suitable as a handle.
  • the transducer rod and the coupling rod preferably form a uniform metal body, so that a lossless coupling and a still compact design can be achieved.
  • the tool part of the ultrasonic transducer can be provided with larger powerful piezoelectric elements, preferably wood cylindrical or annular plates and still has compact dimensions.
  • the annular piezoelectric disks can have an outer diameter, which is a Has multiple of the inner diameter or the diameter of the transducer rod, so that ultrasonic waves can be transmitted with high energy to the coupling rod and the sonotrode.
  • the contact elements preferably brass plates, cover the piezoelectric elements preferably over the entire surface and have connection contacts.
  • the piezoelectric elements and the contact elements which are seated on the transducer rod and which are preferably separated from the transducer rod by an insulation tube are pressed by the pressure element against a stop surface which is provided at the end of the connecting cylinder or the coupling rod facing the ultrasonic transducer.
  • the abutment surface is preferably an annular surface that is congruent with the end face of the adjacent piezoelectric element.
  • the transducer rod preferably has an external thread, of which the provided with an internal thread pressing member is held. By turning the pressing element, the transducer block held between the pressing element and the stop surface can be pressed together.

  • temperature sensors are provided which are provided in openings in the coupling rod, in the connecting bolt, and / or in the transducer rod.
  • the connection lines of the sensors used are preferably arranged in a cable channel which extends coaxially through the transducer rod. Based on the temperature sensors, the temperature of the coupling rod and the transducer rod can be measured.
  • the ultrasonic generator can be advantageously controlled in order to reduce or completely avoid the emission of ultrasonic energy to the tool part under unfavorable working conditions. In this way, it is possible to detect an unfavorable operating behavior and to avoid damage to the tool part.
  • an additional piezoelectric element is provided, which can scan the vibrations on the transducer rod, on the connecting cylinder or on the coupling rod.
  • the advantageous construction of the tool part is thus allowed to build this together in a simple manner and to integrate into the housing part.
  • the transducer rod or the connecting cylinder or the coupling rod is preferably provided or connected to an outer flange, which is held by an inner flange which projects into the cross-section of the wood-cylindrical housing body.
