Definitions

  • the present invention describes an uncontrolled Kirstrommagnetmagnetierer, comprising an AC circuit and an AC voltage source, wherein the AC circuit by means of actuation of a switch, the AC loading of a parallel resonant circuit, comprising a demagnetization and a demagnetizer parallel-connected parallel capacitor allows.
  • uncontrolled Konstromentmagnetisierer For degaussing ferromagnetic components or components with ferromagnetic components, uncontrolled Konstromentmagnetisierer be used for some time.
  • an alternating current flow is generated by at least one inductance and thereby an alternating magnetic field in the vicinity of the inductance.
  • the uncontrolled AC magneto In order to generate sufficiently high alternating magnetic fields, the uncontrolled AC magneto must be designed such that a current flow of several amps through the at least one inductor safely can flow.
  • the uncontrolled Schoolsstrommagnetmagnetierer usually available in the form of Plattenentmagnetisierern or handheld demagnetizers are manually operated and handy, with a simple electronic circuit is used.
  • the alternating alternating voltage can be easily switched on and off by means of a switch, wherein after switching on, the alternating voltage is applied uncontrolled to the at least one inductor and the corresponding alternating magnetic field is induced until it is switched off.
  • the alternating magnetic field has a defined amplitude and a constant frequency, defined by the applied alternating voltage.
  • the at least one inductance in the form of a correspondingly designed coil is usually magnetically coupled to C / E cores of ferromagnetic material.
  • the coils can be covered with plates, which also protects the coil.
  • the plates can each still be provided with a special coating, so that the components can slide over the plates almost smoothly.
  • a parallel resonant circuit comprising a parallel capacitor and a demagnetizing coil is used. After excitation of the parallel resonant circuit and switching off the supply of alternating voltage oscillates this, the Current amplitude automatically oscillates to zero and thus a magnetic alternating field with decreasing amplitude can be easily generated without control.
  • the parallel resonant circuit is applied after turning on a switch with an AC voltage, whereby the demagnetization process can be started.
  • a demagnetizing component is moved over the plate surface of the Plattenentmagnetisierers manually or for example by a transport device, wherein the component is moved into and out of the field lines again. For best demagnetization this should be done by approaching the Plattenentmagnetisierer, sweeping the plate as perpendicular to the pole transition of the C- or E-core Entmagnetisierpule and as far as possible removal of the component from the plate and thus from the field of magnetic field lines.
  • the demagnetizing process is carried out, optimum demagnetizing results can be obtained. In reality, however, the process looks different as part of a production process.
  • a hand demagnetizer If a hand demagnetizer is used, then in the optimal case, after being switched on, it is guided to a component to be demagnetized, then moved as uniformly as possible over the surface of the component at a minimum distance, and the hand demagnetizer is then removed continuously from the component. Due to the high alternating magnetic field, a continuous movement with a constant distance to the component is often not easy. The hand demagnetizer partially sticks firmly to the surface of the component and can only be moved jerkily. For simplicity, the hand demagnetizer is simply turned off to move it away from the surface. Again, unwanted residual magnetic fields remain in the component.
  • the component appears to be demagnetized because demagnetization has been performed from power on to turn off.
  • the resulting disturbing residual magnetic field is usually higher than before the demagnetization process.
  • the demagnetization process must be fast be performed and the competent persons often have no idea of the processes in the demagnetization, resulting in components with strong residual magnetism.
  • the prior art has gone from uncontrolled AC magnetic solenoids to more sophisticated electronically controlled automated demagnetizers. These are much more expensive and more complicated, but offer the user after placing the demagnetizing component the possibility of passing a controlled demagnetization curve.
  • the alternating magnetic field is controlled down controlled, with a residual magnetism within the component is achievable, which is less than the strength of the earth's magnetic field.
  • the controlled demagnetizers in the premium segment are extremely easy to use, which virtually eliminates errors during demagnetization.
  • This circuit can also be used for demagnetization coils, for example tunnel demagnetizers, which have no coupling due to an additional ferromagnetic laminated core.
  • the parts to be demagnetized themselves produce the magnetic coupling.
  • the Parts are de-magnetized through or over the opening of the coil.
  • the present invention has for its object to provide simple and inexpensive uncontrolled Konstromentmagnetisierer with which the error rate of demagnetization also by users who have no idea of the processes during demagnetization to minimize.
  • the inventive solution can be integrated with little additional effort in conventional hand, plate or Tunnelentmagnetisierer.
  • the considerably more complex and expensive version with external power modules or control units for pulse / ramp control is thus eliminated.
  • An uncontrolled alternating current magnetizer 1 is described, which can also be used by laypersons to carry out an optimized, less fault-prone demagnetization method.
  • the alternating current magnetizer 1 has an AC circuit 10, which may be mounted in a housing 11.
  • the AC circuit 10 includes a parallel resonant circuit P having a demagnetizing coil L as an inductance and a parallel capacitor C1 as a capacitance. Both components are connected in parallel.
  • the demagnetizing coil L consists of a plurality of turns, which are advantageously wound as closely as possible so that high magnetic field strengths can be achieved and, depending on the embodiment, can have a cylindrical or rectangular design.
  • the parallel capacitor C1 is usually chosen as the standard motor capacitor. Typical capacitances of the parallel capacitor C1 are between 4 ⁇ F and 40 ⁇ F.
  • the parallel resonant circuit P is fed by an AC voltage source 100 which is likewise arranged parallel to the demagnetizing coil L and to the parallel capacitor C1, wherein an AC voltage having a constant frequency f and an AC voltage amplitude UAC can be acted upon by means of the AC voltage source 100.
  • the alternating voltage induces a current flow and a resulting alternating magnetic field in the demagnetizing coil L.
  • the frequency f can be the mains frequency of 50 Hz or 60 Hz in the simplest case, while the alternating amplitude should be constant.
  • the AC circuit 10 is made switchable by a switch S, wherein when the switch S is applied, the AC voltage at the parallel resonant circuit.
  • demagnetization of the AC circuit 10 is acted upon by turning on the switch S with the AC voltage.
  • An alternating magnetic field builds up in the region of the demagnetizing coil L.
  • Demagnetizing components 13 are subsequently guided along a plate side 12 on the demagnetizer or the demagnetizer on the components 13 to be demagnetized.
  • the demagnetizing components 13 dive into the alternating magnetic field and then move away from the alternating magnetic field, resulting in demagnetized components 14 with almost no residual magnetic field.
  • the invention is based on the idea by circuitry measures to minimize incorrect manipulation during demagnetization and thereby increase process reliability.
  • a semiconductor device D is integrated into the AC circuit 10, which is connected in series with the AC voltage source 100 and by means of the switch S is actuated.
  • the semiconductor device D is a triac, with which the alternating current in the AC circuit 10 controlled while avoiding a switch-on current pulse can be turned on.
  • the semiconductor device D is a current-limiting semiconductor device D, which switches the AC voltage in the zero crossing, whereby a high inrush current, which would arise due to the parallel capacitor C1, is avoided in the AC circuit 10.
  • a series capacitor C2 is connected in series with the demagnetizing coil L and thus arranged within the parallel resonant circuit P.
  • the series capacitor C2 prevents a current breakdown, which can occur during operation of the uncontrolled demagnetizer 1 by manipulating the inductance of the demagnetizing coil L by approaching the demagnetizing ferromagnetic components 13.
  • the series capacitor C2 is a standard motor capacitor.
  • parallel capacitor C1 and series capacitor C2 are configured identically.
  • the time course of a demagnetization is based on FIG. 2 explained.
  • the uncontrolled demagnetizer 1 is switched on by means of switch S at a time t0.
  • the AC circuit 10 is only at zero crossing of the AC voltage UAC time-delayed at time t1 applied to the AC voltage UAC, whereby the inrush current due to the capacitor C1 is effectively limited and the switch-on phase I passes into a mains-powered phase II ,
  • the alternating voltage UAC with a frequency f and defined amplitude leads to an alternating current in the alternating current circuit 10 and an alternating magnetic field induced in the demagnetizing coil L with a magnetic field amplitude A with frequency f.
  • the component to be demagnetized 13 is preferably only during the mains-powered phase II, which usually takes a few seconds, in the region of the demagnetizing coil L past the uncontrolled demagnetizer 1.
  • the switch S After passing the component to be demagnetized 13 and demagnetization, the switch S is switched at a time t3, whereby a switch-off phase III is started.
  • the AC voltage UAC is separated from the AC circuit 10 and there is a decay of the parallel resonant circuit P with the resonant frequency f0 of the parallel resonant circuit P to a magnetic field amplitude A of zero at a time t4.
  • the resonant frequency f0 of the resonant circuit is greater than the excitation frequency f of the AC voltage UAC.
  • the parallel resonant circuit consists of C1, C2 and L in this phase.
  • the AC voltage source 100 preferably supplies a constant peak-to-peak AC voltage amplitude UAC and the frequency f of the AC voltage is freely adjustable to a constant value in a frequency range of approximately 1 Hz to 100 Hz, so that the AC voltage source 100 for the desired demagnetization results at excitation frequencies f of 1 Hz to 100 Hz can be used.
  • the AC voltages with 50Hz and 230V or 60Hz and 115V supplies.
  • the semiconductor device D may be formed of a plurality of thyristors, which are connected accordingly.
  • two thyristors are connected in anti-parallel to each other.
  • the capacitances of the capacitors C1 and C2 and the inductance of the demagnetizing coil L should be chosen such that the resonant frequency f0 of the parallel resonant circuit P is approximately a factor of 2 to 4 times greater than the mains frequency of 50 Hz or 60 Hz should.
