Definitions

  • a press device which is provided with a fault monitoring function.
  • a physical variable such as, for example, the electrical current or the force to be applied, is monitored via an actual value pickup and compared with a setpoint value curve. As soon as the actual value course deviates from the setpoint course in an inadmissible manner, this is indicated via a signal device or the drive motor is switched off.
  • the EP 1 230 998 A2 a method for automatic control of electro-hydraulic hand tools and in particular hand presses, in which the drive motor is automatically switched off after completion of the pressing operation. As an indicator of the completion of the pressing process, each current drop is monitored after opening the pressure relief valve.
  • the object of the invention is to provide a hand-held drive device for pressing devices, in which the reliability is improved. It is another object of the invention to provide a corresponding method for controlling a hand-held drive device for pressing devices.
  • the object is achieved according to the invention by a handleable drive device according to claim 1 or a method for controlling a handleable drive device according to claim 10.
  • the drive device has an actual value sensor for detecting the rotational speed of the drive motor.
  • the drive motor is switched off when the evaluation device detects an increase in the detected by the Istwertaufêt actual speed after opening the pressure relief valve.
  • the invention is based on the consideration of carrying out a plausibility check at the end of the pressing process.
  • the pressing process is terminated in a first control, when the pressure relief valve opens and thus a predetermined pressure, which correlates to the pressing pressure, is constructed.
  • a predetermined pressure which correlates to the pressing pressure
  • it is also checked whether the recorded data confirms that the drive motor is also in an operating condition that corresponds to a successful pressing process. An operator is then preferably notified as to whether the pressing process has been completed properly or not.
  • the speed directly correlates to the pressing force, with a high speed equal to a low load and a low speed indicative of a high load.
  • a target load speed can be defined, which must be undercut for reaching a prescribed pressing force. Falling below this predefined target load speed means that the required pressing force has been achieved.
  • the target load speed forms the upper limit of a downwardly open target load speed range, which is stored in the evaluation device.
  • a lower limit for the permissible target load speed range can also be defined in order to detect overshoots of the permissible pressing force in this way.
  • the evaluation device detects the idling speed before the beginning of a compression and predetermines the target load speed range as a function of the measured idling speed. In this embodiment, therefore, first the idle speed is measured. This is the speed with which the press unit moves without load to a fitting. If the idle speed is low, so will the load speed when opening the pressure relief valve will be lower, and in reverse, the idle speed is high, so the load speed will be higher. Accordingly, the target load speed range is predetermined as a function of the idle speed measured before the pressing process. This can be determined empirically.

  • the speed sensor on its periphery wear a magnet as a contactor and the sensor detects the outgoing of the magnet magnetic fields and corresponding signals to the control device.
  • Optical contactors are also possible.
  • the speed sensor receives from the attached to the output shaft of the drive motor or elsewhere in the drive train magnet per engine compartment rotation in each case a plurality of pulses that are counted. Due to the design-related pulsating load of a hydraulic piston pump, a smoothing of the speed curve may be necessary. This is done by calculation and depends on the structure of the pump and the gear ratio. An advantage of this method is that only counts the pulses and the speed is calculated from the number of pulses. An AD Wandier as in current or voltage measurements is not required here, which makes the evaluation easy.
  • the hydraulic motor can be designed in a manner known per se as a piston-cylinder unit with a hydraulic cylinder and a hydraulic piston.
  • the pressure relief valve in the hydraulic piston and / or in a piston rod of the hydraulic piston is arranged (see. DE 203 03 877 UI and DE 20 2004 000 215 U1 ).

  • the detected after opening the pressure relief valve actual speed is compared with a stored target speed range in an evaluation.
  • a stored target speed range By means of such a comparison, it can be ensured in the context of the plausibility check that a correct compression has been carried out when the detected actual rotational speed is within the desired rotational speed range.
  • it can be displayed by means of a signaling device, whether the actual speed is within the stored target speed range and thus a proper compression was performed.
