摘要： An ultrasonic vibration device has a sonotrode and a converter, the converter having a piezoelectric actuator for converting an electrical alternating voltage into a mechanical vibration. A first piezoelectric sensor element outputs a first measurement signal which varies in dependence on the vibration amplitude of the mechanical vibration. To permit measurement of at least one intensive state variable like the temperature, or the aging state of the piezoelectric actuator, a second piezoelectric sensor element outputs a second measurement signal which also varies in dependence on the vibration amplitude of the mechanical vibration. However, the second piezoelectric sensor element differs in a physical property from the first.

摘要： The invention relates to a method for operating an ultrasonic welding machine. During a welding process, a flat material is continuously moved through a gap formed between a sonotrode (1), which is vibrated at an ultrasonic frequency with a welding amplitude, and an anvil (2) at a welding speed while a welding force is exerted onto the flat material by the anvil (2) and/or the sonotrode (1). The invention is characterised in that during a welding phase, the ACTUAL temperature of the flat material is measured after the flat material has passed through the gap, the ACTUAL temperature is compared with a predetermined TARGET temperature, and the welding amplitude is varied on the basis of the comparison result.

摘要： The present invention relates to a method for ultrasonic treatment of a plastic material, comprising the steps of: positioning the plastic material between a sonotrode and a counter-tool, bringing the sonotrode excited by means of an ultrasonic oscillation into contact with the plastic material during a welding phase, moving the sonotrode and the counter-tool towards each other during a holding phase, in which neither the sonotrode nor the counter-tool are excited with an ultrasonic oscillation so that a force F is applied onto the plastic material. In order to reduce treatment times, wherein at the same time the quality of the welding process is not impaired but is even to be improved, it is proposed according to the invention that the force F is varied during the holding phase.

摘要： The cutting of fibrous material which does not melt easily is effected to avoid the unravelling of cut edges, using ultrasonic or laser beam techniques. The method includes (a) applying a thermoplastic powder material to the cutting region, and (b) applying thermal shock to the localised area, sufficient to destroy the fibres of the material, and melt the powder on either side of the cut, and (c) pressing the cut edges while the fused thermoplastic powder is still soft. Woven or non-woven fabrics have tendency to unravel, after cutting, and normally require a sewn hem. The method of the invention disposes of the sewn hem, and provides a thermo-cutting technique applicable to non-fusible or non-thermoplastic fibres.

摘要： The present invention relates to a method for intermittent ultrasonic processing of a length of material, wherein a length of material is moved through between a sonotrode and a counter-tool and the length of material is processed intermittently. In order to specify a method for intermittent ultrasonic processing of a length of material by which the disadvantages of the prior art can be avoided or at least reduced, according to the invention it is suggested that in a processing interval the sonotrode is stimulated by an ultrasonic oscillation with an oscillation amplitude A and in a movement interval the sonotrode is stimulated with an oscillation amplitude B, wherein B

摘要： Invention relating to a method for controlling an ultrasonic machining, in which an ultrasonic vibration is transmitted via a sonotrode into the material to be machined. During the first machining interval, a first welding variable of the group S, consisting of the frequency f and the amplitude ü of the ultrasonic vibration, the force F, which the sonotrode exerts on the material to be machined, the power P, which the generator delivers, and the speed v, with which the sonotrode is moved in the direction of the material to be machined, is kept constant until a first target variable of the group Z adopts a predetermined value. During an adjoining second machining interval, a second welding variable of the group S is kept constant until a second target variable of the group Z adopts a predetermined value, wherein the first and the second target variable differ.
