摘要:
A pressure welding device (1), especially a friction welding device, holds workpiece parts (2, 4) in clamping devices (6, 7) and axially moves the workpieces towards each other by means of a feed device (21). The pressure welding device (1) has a measuring device (8, 13), measuring in a contactless manner. The measuring device detects the surface condition and/or the concentricity and/or true running and/or the axial runout and/or radial runout in a front welding region (3, 5) of a workpiece part (2, 4).

An ultrasonic welding system includes a motion control system that is coupled to and that causes controlled movement of an ultrasonic welding stack, in accordance with control inputs that are based on one or more control signals that are received from one or more sensors. The motion control system initiates a welding operation, subsequent to which an initial motion delay occurs until a predetermined condition is satisfied. Subsequently, in response to the predetermined condition being satisfied, the ultrasonic welding stack is caused to move in accordance with a weld profile. Subsequently, in response to an occurrence of a predetermined delay initiating condition, the ultrasonic welding stack is caused to stop motion and to maintain a stationary position. Subsequently, in response to an occurrence of a predetermined delay terminating condition, motion of the ultrasonic welding stack is resumed in accordance with the weld profile.

An ultrasonic processing method and an ultrasonic processing device may include a controlling/regulating module, preferably a digital controlling/regulating module, which is integrated into a signal processing of the ultrasonic generator so that a plurality of generator data with respect to the ultrasonic generator are processible in the ultrasonic generator. At this, a power actual value Pist is compared with a power reference value Psoll of the ultrasonic generator via a gap regulator in the controlling/regulating module to specify a position reference value POSsoll of the sonotrode relative to the roll for adjustment of the power reference value Psoll of the ultrasonic generator, and/or a power actual value Pist is compared with a power reference value Psoll of the ultrasonic generator via an amplitude regulator in the controlling/regulating module to specify an amplitude reference value Asoll to the ultrasonic generator for adjustment of the power reference value Psoll.

A device for acting on a material web using ultrasonic includes an ultrasonic unit which has a converter a booster and a sonotrode, and a counter tool. The material web is guided through a gap between the sonotrode and the counter tool and acted upon by the sonotrode. The ultrasonic unit is adjustable relative to the counter tool by way of a movable carriage, and the booster is firmly connected to the carriage. A support supports at least one side surface of the sonotrode and guides the sonotrode in the longitudinal direction thereof.

An ultrasonic sealing jaw (1) is used for sealing portions of plastic film to a tube so as to form a sealing engagement of the portions of plastic film around the circumference of the tube. The sealing jaw (1) includes a concave film-tube welding portion (7) for receiving the tube covered by the plastic films the film-tube welding portion (7) to form the film-tube attachment. Adjacent to at least one side of the film-tube welding portion (7) of the sealing jaw (1), is a substantially flat film-film welding portion (3, 4) for engaging the plastic film and sealing adjacent portions of plastic film to each other in an area adjoining the tube. A film-film welding portion (3, 4) defining a top plane (10) of the sealing jaw (1) has at least one recess with a surface (11) so as to form a cavity (12) and forms a cavity (12) with an opening towards the film-tube welding portion (7).

The device for sealing together a formed bottom sheet and a lidding sheet between a feed roll and a sealing roll has a heating unit for preheating the lidding sheet before the sealing operation. The heating unit is a contactless induction heating device which has coils and magnetic-field influencing elements which are arranged transversely to the travel direction of the lidding sheet and opposite at least one of the coils. The distance between each of the magnetic-field influencing elements and the at least one coil is adjusted by a control unit on the basis of measurement values of temperature sensors arranged downstream of the magnetic-field influencing elements in order to regulate the temperature profile of the lidding sheet.

The invention relates to a method for axial joining of a hybrid joining component to a workpiece, wherein the joining component has a thermoplastic joining section and a metal section which can be heated, having the following steps: moving the joining component into contact with a surface of the workpiece; heating of the metal section such that the joining section at least partially melts; ending the heating of the metal section such that the joining component makes a force-fitting, interlocking and/or integral connection with the surface of the workpiece. In this case, the joining component is held with a regulated force and/or in a regulated position with respect to the workpiece at least during the heating of the metal section, in such a manner that the joining component can be joined to the surface of the workpiece without any opposing support.

An anvil has a temperature adjustment mechanism including a heater. The anvil has a heat transmitter transmitting heat generated by the temperature adjustment mechanism. The anvil has a temperature sensor detecting a temperature of an anvil attachment portion in which the anvil of rotating drum installed. The ultrasonic joining apparatus includes a controller configured to control a temperature to which the rotating drum should be heated by the temperature adjustment mechanism. The controller controls a heat generation amount of the temperature adjustment mechanism on the basis of a detection result by the temperature sensor. The temperature adjustment mechanism and the heat transmitter are installed in each of the multiple anvils.
