Definitions

  • the present invention relates to a method of setting rivet elements by a portable riveting tool driven by an electric motor, comprising a setting device in which the force of the setting device with which a rivet element is set is monitored on the basis of the current absorbed by the electric motor. Furthermore, the invention relates to a portable riveting tool for setting rivet elements, which is driven by an electric motor.
  • the setting of rivet elements is well known. So is out of the DE 10 2005 054 048 A1 discloses a method of setting rivet elements by a riveting tool driven by an electric motor. The quality of the setting process is monitored by means of the electrical current absorbed by the electric motor of the riveting tool. The quality of the setting process is considered to be acceptable if the maximum absorbed by the electric motor during the setting process within a predetermined range of values.
  • the disadvantage of this method is that the quality of the setting operation of the riveting device is evaluated only on the basis of the maximum recorded current. This allows only a retrospective consideration of the setting process. The riveting process is carried out to the end in this process. Therefore, it can not be judged at which point of the setting process the setting operation has been performed erroneously.
  • the maximum absorbed current is within the specified value range.
  • the rivet was pulled too fast or too slow in one place, this can not be determined.
  • a method for setting blind rivets and blind rivet nuts in which in a setting process, a tensile force with the help an electric motor is generated. Further, a setting tool for blind rivets and blind rivet nuts with a driven by an electric motor pulling mechanism is known. In this method, the input current of the electric motor is monitored, wherein the absorbed current is directly a measure of the torque absorbed by the electric motor. About the moment the tensile force of the setting of the setting device can be determined. The tensile force allows a conclusion on the quality of the riveted joint. Thus, the current profile can be used afterwards as a criterion for evaluating the setting process.
  • the object of the invention is to provide a method for setting rivet elements by a driven by an electric motor portable riveting tool and such a riveting tool, which allows the assessment of the setting process already during the setting process of a rivet. This is how it should be possible to abort the setting process even if an error is detected during the setting process. Furthermore, a method for setting rivet elements and a riveting device is to be provided, which enables the setting process to be actively changed during the setting process.
  • the core of the invention is that the distance traveled by the rivet element and / or the setting device is measured repeatedly by a sensor device and the applied force of the setting device is determined for each measuring point. By comparing the force applied at each measuring point of the setting device with reference force value ranges for the respective measuring point, one can immediately Assessment of the quality of the setting process to be made.
  • the riveting tool has a memory unit in which reference power value ranges are stored for each measuring point. Different reference force value ranges can be stored for different rivet elements. Thus, for each rivet element, over the entire setting process, there is a band area in which the force applied by the setting device should lie. This band region extends from the beginning of the path to the end of the path covered by the rivet element or the setting device. As soon as it is determined at a measuring point that the force applied by the setting device is outside the predetermined reference force value range for this measuring point, the setting process is not accepted. If the determined values at each measuring point are within the specified reference value ranges, the setting process is accepted.
  • An advantage of this method is that it can be determined immediately and accurately from when the setting process went wrong. It is possible to draw immediate conclusions regarding the setting process.
  • the assessment of the setting process can be performed very frequently by the repeated measurement and is therefore not only dependent on the maximum absorbed current. In other words, an error in the setting process can also be detected before or after reaching the maximum current consumption of the electric motor. Due to the non-acceptance of a setting process, a user, usually a worker, can immediately recognize that a rivet element has been set incorrectly. Thus, an error when gripping the gripping jaws of the setting device can already be determined if the force with which the gripping jaws grip is above or below a reference force range for this distance after a certain distance.
  • Repeated measurement means in the sense of the invention that it is determined when a particular plug has been covered by the rivet element or the setting device. After covering each particular distance each time a measurement of the applied force of the setter is performed. That is, for a plurality of distances, the force applied by the setting means is determined on the rivet element. In this case, the applied force is determined every few millimeters or micrometers. It is also conceivable that every few nanometers one Measurement takes place. The frequency of the measurements, ie the distances after which a measurement is carried out, can be determined beforehand.
  • the force of the setting device applied for setting the rivet element is regulated as a function of the distance traveled by the rivet element or the setting device by a control unit of the riveting device.
  • This allows a correction of the setting process during the setting of the rivet element.
  • the riveting tool can actively intervene in the setting process and change it.
  • the control unit recognizes on the basis of successive measuring points whether the setting speed is too fast or too slow. If it is found that the setting speed and therefore the force with which the rivet element is pulled are too high, the control unit can throttle the applied force in order to slow down the setting speed. If the control unit determines that the rivet element is pulled too slowly by the setting device, this can increase the setting force and thus the setting speed. This means that the control unit can regulate the current of the electric motor of the riveting tool as needed.
  • the distance measurement can be done by incremental or analog displacement sensors.
  • laser sensors, photoelectric sensors or inductive or capacitive sensors can be used for distance measurement.
  • the riveting tool is portable.
  • the riveting device preferably has an accumulator which supplies the riveter with electrical energy. This allows a very flexible use of the riveting tool.
  • a process-safe, accumulator-operated, portable riveting device can be created.
  • an acoustic or visual error indication is made on the riveting tool. This immediately indicates that the setting process has expired incorrectly. For example, when a fault is detected during the setting process, an acoustic sound can be output.
  • the riveting tool has a speaker unit in this embodiment.
  • an optical display device in particular in the form of a display or a lamp, such as an LED, may be provided. If a faulty setting process is detected, for example, the message "NOK”, ie "not OK", can be displayed on the display.
  • the riveting tool thus has a self-diagnostic function which always produces a "no" result in the event of a parameter failing or drifting off. Since all measurement results are subjected to dynamic processes, a misbehavior of the setting process is recognized immediately. Such a method thus enables a plausibility check. If the determined values at each measuring point lie within the predetermined reference force value ranges, the setting process is accepted, which can be represented by the display "OK”, ie "OK".
  • the applied force of the setting device is represented in relation to the distance traveled by the rivet element or the setting device.
  • the reference force value range can be displayed on the display device.
  • Also preferred is a method for setting a rivet element in which, in addition to the determination of the distance and the detection of the applied force, the time of the setting process is detected.
  • the applied for setting the rivet element The force of the setting device can then be regulated or controlled as a function of the distance traveled by the rivet element or the setting device and the time required for the distance traveled. By changing the force with which the setting device pulls the rivet element, the setting speed can be influenced.
  • the setting process of the rivet element is terminated after reaching a determinable maximum force.
  • the setting process of the rivet for example, the Blindnietbolzens or blind rivet nut, when reaching a preset force, the setting process is reliable. After reaching the set maximum force, the setting device automatically spindles.
  • the distance traveled by the rivet element during the setting process and / or traveled by the setting device during the setting operation of the rivet element is determined by measuring the angle of rotation of the electric motor of the riveting device, a comparison of the ascertained setting paths can be made possible. In other words, a further displacement measurement is carried out in addition to the path measured by the sensor device.
  • This parallel path measuring system or the redundant distance measurement increases process reliability.
  • the measurement of the angle of rotation can be done via Hall sensors.
  • the setting speed of the rivet element or of the setting device can be kept constant over a determinable distance interval or over several determinable distance intervals, wherein the setting speed of a distance interval can be different from the setting speed of another distance interval. That is, the setting speed of the rivet member can be changed. For example, if a first distance covered, the control unit or the set speed with which the rivet element is pulled, reduce or increase. Thus, the entire route can be divided into different route intervals, wherein for each route interval, a different setting speed can be specified.
  • the setting device of the riveting tool has gripping jaws for gripping the rivet element. It is preferred if, after starting the setting process, the gripping jaws of the setting device are closed with a first setting speed, if after closing the gripping jaws, the rivet element with a second, compared to the first setting speed higher, setting speed is pulled, and if after covering a determinable path of the rivet element or the setting device or a predetermined time, the rivet element is pulled with a third, compared to the second set speed lower set speed. After starting the riveting operation, a "soft start" of the riveting tool takes place until the gripping jaws of the setting device are closed.
  • the abrasion of the rivet element, in particular of the rivet mandrel will be significantly reduced, which in turn will increase the availability and service life of the riveting tool until the next maintenance interval, i. the cleaning of the jaws, significantly extended.
  • the gripping jaws of the setting device are not so quickly filled with metal shavings of the rivet element due to the slow approach of the setting device. After closing the gripping jaws, a quick honing is done by the setting until the rivet has plastically drastically deformed to then achieve a slow and controlled joining of the rivet element to the optimum design of the setting head of the rivet and a rupture of the rivet mandrel by means of a lower setting speed.
  • An additional method step in which all detected paths and / or times, which the rivet element or the setting device has covered, are stored in a storage unit of the riveting device and / or documented in a force-displacement-time diagram a particularly preferred method.
  • a plurality of reference force value ranges, target value window, gradient curves or envelopes for "OK” and "NOK” results can be defined.
  • a specific measuring window can be defined.
  • different measurement windows, reference force value ranges, gradient curves can be specified.
  • the term “OK” means "okay” or "setting process accepted” and the term “NOK” means "not OK" or "setting not accepted”.
