Definitions

  • the invention relates to a method for joining plastic-metal hybrid components, in which a metal component is heated in a heating step and brought in a joining step, a plastic component with the heated metal component in contact and by melting in the contact region with the
  • the invention further relates to a device for joining a metal component and a plastic component.
  • the joining of plastics and metals is basically known in the art and is e.g. performed by the steps mentioned above. It is known to heat a holding device for the metal component and transfer the heat by conduction of heat to the metal component until the desired temperature is reached and the joining step can take place, after which the entire holding device cools. Due to the total heated mass and the Heranikiens from below to the desired joining temperature, such a method is unfavorable and imprecise to call, as long heating and
  • CONFIRMATION COPY Plastic and metal components can be produced and with which short process cycles can be achieved.
  • this is achieved by a method of the type initially mentioned, in which the metal component is heated in the heating step to a temperature above a predetermined bonding temperature, cooled in a subsequent cooling step, in which the temperature of
  • Metal component is detected by means of at least one temperature measuring device and is executed upon reaching the specified joining temperature of the joining step.
  • Achieving the specified bonding temperature may be achieved in one embodiment, e.g. characterized in that a temperature measured by the temperature measuring device or a temperature determined from a plurality of measured temperatures (for example, a plurality of surface areas, in particular the joining profile of the metal component averaged temperature) is compared with a bonding temperature stored in a control.
  • a temperature measured by the temperature measuring device or a temperature determined from a plurality of measured temperatures for example, a plurality of surface areas, in particular the joining profile of the metal component averaged temperature
  • Joining step are triggered when the measured temperature is less than or equal to the stored bonding temperature or is in a specified interval around the bonding temperature around.
  • An essential aspect of this method is that the metal component is quasi overheated in the heating step, i. reaches a temperature which is above the joining temperature which the metal component should have at the time of joining. This has the advantage that a faster energy input is possible because it is no longer necessary to achieve the desired joining temperature targeted from below. Rather, it is unproblematic and advantageously desired that the metal component reaches a temperature above the desired or determined by the materials temperature.
  • the advantage is seen that in the subsequent cooling step by internal heat conduction effects in the metal component, the registered energy is distributed and is released to the environment. As a result, a substantially more uniform temperature distribution is achieved in the metal component at the time of the actual joining step, in particular in a joining contour intended for the joining.
  • the entire receptacle for the metal component is not cyclically heated and cooled, but it can preferably be provided that the metal component is heated with a Schustempelelement which is brought into contact with the metal component.
  • the Schuttempelelement be continuously heated, wherein a heat dissipation then arises when it is brought into contact with the metal component.
  • the amount of energy draining can e.g. by supplying energy, for example by energizing an electric heating element in
  • the heating stamp element can also be provided to select the mass of the heating stamp element so large that no or only an insignificant energy tracking into the heating stamp element must take place during the heating step.
  • the Schustempelelement be heated only if it has no contact with the metal component.
  • This period of time may be selected empirically such that the temperature of the metal component certainly exceeds the desired or predetermined bonding temperature by a predetermined amount. This period of time may e.g. be measured from the
  • Heat stamp element and metal component are detected by sensors, such as a photoelectric sensor or force / pressure sensors and the time from this time are measured. It may also be provided that during the heating step
  • Removal of the Wienstkoviatas is terminated when the temperature of the metal component has exceeded the specified bonding temperature by a predetermined amount.
  • the temperature of the metal component can be detected in a region which is not covered by the heating stamp element, but in particular directly adjoins it.
  • a device for carrying out these method steps can accordingly comprise a heated heating stamp element, as well as suitable actuators for its movement and / or sensors, in particular as will be explained in detail later.
  • a deformation of the metal component is also carried out during the heating step.
  • two process steps in the time interval of heating can be carried out, and it is particularly advantageous that it is a hot deformation in the forming and therefore is particularly gentle on materials.
  • An actuator for moving the Schutkovmaschines is suitable to select powerful in this case, not only to perform a mere contact for the purpose of heating, but also to be able to muster the forces that are needed for the transformation of a metal component.
  • the heating of the metal component beyond the desired joining temperature can also be done in other ways, e.g. also contactless, e.g. by radiation, in particular laser radiation.
  • Radiation cross-section which is smaller than the joining contour, ie as a surface area to be heated of the metal component in which the joining is to take place, it may also be provided in such an embodiment that the radiation profile is actively guided over the surface to be heated during the heating step, ie, the joining contour successively proceeds, for example by beam deflection of a laser beam, for example a CO2 laser.
  • Contactless heating with radiation also has the advantage that the temperature of the metal component which is achieved during the heating step can be measured without contact within the said joining contour, for example by evaluating the thermal radiation which emits the metal component from the joining contour.
  • the heating can be very targeted and finished exactly when the metal component exceeds the bonding temperature by a certain pre-selected level.
  • Such a detection of thermal radiation can be done, for example, by a point-measuring pyrometer or by a flat-measuring thermal imaging camera.
  • heated metal component takes place automatically from the time when the active heating is stopped, e.g. in that a Schustempelelement is withdrawn from the metal component and out of contact or a heated radiation is switched off. Cooling may then be by convention and / or radiation emission or actively assisted in an alternative, e.g. by an air or gas flow.
  • the process of cooling can be done in a possible variant at the place of the previous heating. But it can also be provided that the
  • a device for joining the plastic and metal components takes place, wherein the heated metal component is automatically transported to the joining location after the heating step.
  • a device for joining for example, comprise a transfer device or a transfer element, with which the
  • Metal component is transported to the joint location, in particular together with the receptacle in which it is located and in which the heating has taken place.

  • the heating and joining can take place at the same time.
  • this contactless monitoring has the advantage that the temperature which the metal component receives on cooling can be detected in at least one region of the metal component, which is arranged in a fixed joining contour, within which the joining of metal component and plastic component is to take place. It will therefore be a very accurate

  • a device for performing the joining may, for example, have for this purpose a joining punch provided with an actuator, in / on which the plastic component is held. For example, by a negative pressure.
  • a joining punch is preferably at a location different from the heating location of the device arranged.
  • a transfer device which is designed as a turntable, heating location and joining location by an angular rotation, in particular a 180-degree angular rotation can be removed from each other.
  • the plastic component and the metal component are pressed together and compressed after forming a melt film between the components, in particular after a predetermined time, with a second, larger force.
  • a formed melt film is subjected to a deliberate application of force, which creates a particularly intimate bond between the components, especially if they have rough surfaces, such as e.g. after a sandblast.
