Definitions

  • the invention is based on a method for removing dents from an electrically conductive, flat structure to form a smooth structure, according to the preamble of claim 1 and of an apparatus for carrying out the method according to claim 4.
  • Such flat, electrically conductive structures are, for example, steel sheet bodies of motor vehicles, which are dented by accident damage or environmental effects such as hail.
  • various repair methods are known from the prior art, which apply purely mechanical forces such as bulging, expressions, pulling, etc. on the dent.
  • a method for removing warpage of electrically conductive materials by means of electromagnetic forces in which a first current source generates a first current pulse and a second current source generates a second current pulse of opposite polarity through a coil, wherein the rise time of the second current pulse is shorter than the rise time of the first current pulse and the rise times are in the range of 0.08 to 1.6 milliseconds or in the range of 10 to 40 microseconds. Due to the short, pulse-like action of the electromagnetic field, a strong impulsive electromagnetic force can be generated. More precisely, the first impulse is not completed at all, since otherwise only a repulsive force will arise and the dimple would increase. Therefore, one does not complete the first pulse, but reverses the current through the inductor.
  • the process is no longer influenced after the start, due to the very short duration of action. It is only for the next application, the height of the first current pulse and the degree of inversion on the voltage at the capacitor bank set while the rate of rise of the current pulses and the rate of inversion are given by the hardware.
  • the object of the present invention is to develop a method and a device for removing dents from electrically conductive, flat structures in such a way that it allows a more flexible use and provides better results.
  • the invention uses an inductive method for eliminating dents, with which heat and electromagnetic force are combined.
  • the heat is applied because the dent resulted from the cold deformation of the metallic structure in the area of the dent. Due to this cold deformation, internal stresses develop in the structure, which are eliminated by applying the heat, similar to stress relieving of metals.
  • the heat generated by the electromagnetic field in the electrical conductor in the region of the dent therefore on the one hand causes a reduction in the internal stresses generated by the cold deformation, but at the same time also a material expansion in the plane of the structure.
  • the electromagnetic force acting on the material then ensures that the structure set by the heat and the expansion caused by it under tensile stress in the opposite of the original cold deformation Direction over the smooth state out snaps. Then, when the electromagnetic field is overridden, no electromagnetic force or heat is generated inductively and the resulting cooling of the structure causes it to revert to its smooth state.
  • the effect is based on the fact that an induction coil through which an alternating current flows creates an electromagnetic field in the region of the dent. If the electrically conductive dent penetrates the electromagnetic field, electrical currents are generated in it, which lead to heating of the structure in the region of the dent. At the same time, electromagnetic forces that can have an attractive or a repulsive character act. This means that not only concave but also convex dents in a structure can be eliminated by applying the method according to the invention. When using the inductive method, either pulling forces or repulsive forces (tensile or compressive forces) can therefore be generated depending on the material of the structure and on the desired effective direction of the electromagnetic forces.
  • the method can be applied to all ferromagnetic as well as non-ferromagnetic structures (paramagnetic, diamagnetic materials). It is essential that the structure is electrically conductive, so that by magnetic induction there a current and thus heating can be generated. Among other things, the process is therefore applicable to metallic materials, carbon-based materials such as CFRP materials as well as to all structures in which electrically conductive particles are incorporated.
  • the ratio between the amount of heat introduced in the structure in the region of the dent and the electromagnetic force acting there is dependent on the frequency and the field strength of the electromagnetic field.
  • the magnitude of the electromagnetic force depends only on the field strength, but not on the Frequency of the electromagnetic field.
  • the current actual deformation path is detected by means of a suitable sensor device.
  • the sensor device for detecting the actual deformation path is calibrated to zero with respect to the planar structure or surface, for example, a sign change from plus to minus or vice versa points to the process end, whereupon a stop signal is generated which terminates the action of the induction source, for example in that the electric generator is switched off.
  • suitable sensors can be used, such as proximity or microswitches. The process can then be controlled or regulated via the deformation path as a controlled variable.
  • the induction coil can be provided with a field former or field amplifier, for example in the form of a coil core.
  • a field former or field amplifier for example in the form of a coil core. This can, depending on the selected frequency range for the current of magnetically conductive or electrically non-conductive material (sintered material, pulververpresster material) for higher frequencies, nanocrystalline or amorphous material for the middle frequency range or from transformer sheet (cold or hot rolled) for low Frequencies exist.
  • the electric generator 8 is preferably a generator for generating medium frequency currents in the induction coil 10, which may be connected to the power supply, for example, but may also be battery operated.
  • the physical background of the method which is carried out with the handling device 1, based on the fact that the metallic structure 4 is penetrated by the electromagnetic field such that on the one hand, the structure 4 is heated in the region of the dent 2 and on the other hand from the electromagnetic field on the Delle 2 applied electromagnetic force ensures that the dent 2 snaps in the opposite direction of the original cold deformation direction a piece far beyond the smooth or even state, such as Fig.2 shows. Then, when the electromagnetic field is overridden, the cooling of the structure 4 caused thereby in the region of the dent 2 ensures that it can revert to its smooth state, as it does in FIG Figure 3 is shown.
  • the heat generated by the electromagnetic field in the electrical structure 4 in the region of the dent 2 causes, on the one hand, a reduction in the internal stresses generated by the previously found cold deformation, but at the same time also a material expansion in the region of the dent 2.
  • the effect on the material of the dent 2 acting electromagnetic force then ensures that the set by the heat and the expansion caused by stretching under tension material 2 is pulled in the direction of a smooth structure 4 and beyond over in the opposite direction of the original cold deformation direction overshoots over the smooth zero position, as from Fig.2 evident.
  • the electromagnetic field is overridden, so that caused by this cooling and relaxation of the structure 4 in the region of the dent 2 ensures that they are in the smooth state according to Figure 3 can deform.
  • the method can be applied to metallic ferromagnetic as well as to non-ferromagnetic structures 4 (paramagnetic, diamagnetic materials), it is essential that the material is electrically conductive, so that there by magnetic induction, a current and thus heating can be generated.
  • dining electric generator 8 is preferably designed such that in particular the current and the frequency of the induction coil 10 flowing through the stream is controllable.
  • the frequency and / or current of the current flowing through the induction coil 10 is then varied during application of the method to vary the ratio between the two quantities of heat and force by the operator.
  • the operator receives a visual feedback in that the structure 4, for example, not yet sufficiently deformed, so that the mentioned process parameters must be readjusted on the electric generator 8.
