Definitions

  • the invention relates to a method for the thermal treatment of at least one metal body. Furthermore, the invention relates to an apparatus for carrying out such a method.
  • the inductive heating and the heating by laser are known. Both methods allow a local thermal treatment on a defined partial surface of a metal body. Due to the rapid local heating of the material disadvantages such as a distortion of the metal body and thus deviations after heating arise, a difficult Control and control of the temperature in the heating field due to uneven distance between the heat source and the plate due to distortion, uneven temperature distribution on the heating zone causing inhomogeneous material properties, and partial or complete destruction of the zinc layer by evaporation in metal bodies with a zinc layer.
  • the invention has for its object to provide a comparison with the prior art improved, in particular a low distortion and / or improved in terms of temperature control process for the thermal treatment of metal bodies. Furthermore, a device for carrying out the method is to be offered.
  • the at least one metal body is fixed in its position.
  • a first contact plate is brought into contact with at least a first surface section of the metal body and a second contact plate is brought into contact with at least one second surface section of the metal body.
  • the contact plates are surface substantially or completely formed according to the contour of the surface portions of the metal body and in the state of contact with the metal body substantially parallel to each other arranged.
  • at least one contact plate during the contacting of the metal body has a relation to the metal body higher or lower temperature.
  • the temperature of the metal body compensates during contacting the temperature of the contact plate. This leads to a thermal treatment of the metal body. It is thus possible both heating and cooling of the metal body by contact plates. In addition, the temperature-induced distortion is minimized by the uniform temperature change and the surface pressure through the contact plates.
  • the method according to the invention can be used variably.
  • the temperature which the contact plate has or on which the metal body is brought, as well as the period of time for which the contact between contact plates and metal body can be chosen almost arbitrarily. It is thus possible to variably adapt the method according to the invention to the desired parameters of the thermal treatment and to the material to be treated. In particular, both thermal treatments are possible, which lead to a softening of the material as well as thermal treatments that lead to a solidification.
  • the contact between metal body and contact plates may be formed such that the contact plates and the metal body touch directly. However, it may also be an intermediate layer, such as a contact agent, which improves the temperature balance between the contact plate and metal body, be present.
  • the surface portions communicating with the contact plates may extend over or cover completely large portions of the metal body as well as forming only small, localized areas of the metal body. If only locally limited areas are connected to the contact plates, a local thermal treatment of the metal body can be carried out.
  • the metal body is formed as a sheet metal or sheet metal part and the at least one first surface portion is located on the upper side of the sheet metal and the at least one second surface portion is located on the underside of the sheet metal.
  • a metal body is at least partially with a zinc layer provided sheet metal or sheet metal parts used.
  • a zinc layer provided sheet metal or sheet metal parts used.
  • high-strength, galvanized sheets and sheet metal parts can be used from the body shop.
  • the contact between metal body and contact plate prevents the damage or destruction of the zinc layer.
  • a metal body is used, which is formed in a later step, and the at least one first and second surface portion are in or near the area to be reformed later.
  • the contact plates are pressed onto the metal body. This has the advantage that a contact between contact plates and metal body is ensured particularly secure. In addition, thereby minimizing the delays is particularly effective possible.
  • the temperature of the at least one contact plate with elevated or lowered temperature before and / or during the contacting of the metal body with the contact plates is controlled by a temperature control device.
  • a temperature control device it is possible the temperature of the contact plate and thus also the temperature of the metal body during the entire thermal treatment control or regulate.
  • such a control device both preheat prior to contacting the contact plates, heat the contact plates during contacting, keep a desired temperature during contacting constant or provide for a controlled lowering of the temperature in the course of contacting.
  • the control device can also provide for a defined cooling of the contact plates.
  • a contact plate is removed. If all the contact plates removed, this leads to a free alignment of the temperature of the metal body to the ambient temperature. If a contact plate is removed, this leads to a partial free alignment of the temperature of the metal body. In areas of the metal body, which are still associated with a contact plate, the temperature of the metal body, however, is influenced by the contact plate. This makes it possible to influence the formation of the temperature profile of the metal body by removing one or more contact plates.
  • first contact plates and / or the second contact plates are interconnected with a flexible transition element. This allows the individual contact plates to adapt flexibly to different geometries of the basic body.
  • the metal body is heated in a first method step and brought into contact with at least one contact plate in a subsequent method step.
  • the contact plate has a relation to the metal body lower temperature. Due to the lower temperature of the contact plates, the metal body is cooled after heating. This cooling is well controlled due to the contact plates in terms of temperature control.
  • the heating of the metal body can be done by contact with contact plates, which have a higher temperature than the metal body.
  • the metal body can also be heated without contact with contact plates, for example with an inductor.
  • the same contact plates in the subsequent process step can also be brought to a temperature lower than that of the metal body and thus serve for cooling. But it can also be used for heating other contact plates than for cooling.
  • the metal body is brought into contact with at least one contact plates in a first method step.
  • the contact plate has a relation to the metal body higher temperature. Due to the higher temperature of the contact plates, the metal body is heated. This heating due to the contact plates in terms of temperature control is well controlled. In addition, will minimized due to the contacting of the warp caused by warpage.
  • the at least one contact plate which has an elevated temperature relative to the metal body, is preferably heated to this temperature by an energy source. This can be done, for example, inductively or conductively.
  • the heating can take place either before the contact with the metal body or during the contacting.
  • the contact plates can also be brought into mutual contact with one another before the contact with the metal body. It can then be heated a contact plate. The heat then transfers to the others with these contact plates in contact. Subsequently, the contact plates can be separated from each other and brought into contact with the metal body.
  • the contact plates can both be made of the same material as well as of different materials.
  • contact plates that are heated made of a metallic material, such as steel.
  • Contact plates that are not heated may preferably be made of both metallic and non-metallic materials.
  • contact plates, the not heated made of an insulating material. This has the advantage that the heat loss is reduced.
  • the contact plates may have an insulating layer. Also, the heat loss can be reduced thereby.
