  • a sub-step is, for example, the heating of the sheet metal part 3 in a continuous furnace.
  • steps III and IV can also be summarized, which is represented by a binding clip.
  • the board 2 can first be heated and then formed in a cool forming tool and simultaneously cooled or even quenched, whereby a hardening and possibly also increasing the strength of the steel sheet material 1 (strictly speaking, the steel material 10) occurs.
  • the sheet metal part 3 may also be subjected to another heat treatment.
  • the press hardening process can optionally be followed by a further heat treatment of the sheet metal part 3, such as tempering.
  • the method and in particular at least one of the steps II, III or IV, is carried out in such a way that a sufficient layer quality of the protective layer 13 is achieved with respect to a subsequent coating and / or joining of the sheet metal part 3, so that the protective layer 13 can remain on the sheet metal part 3.
  • the mandatory removal of such a protective layer 13 is provided to coat the sheet metal part 3 and / or add.
  • a protective layer 13 having a sufficient layer quality in this sense is e.g. from, by low cracking, good adhesion to the anticorrosive coating 12, proper thickness and / or density, beneficial surface roughness, composition and the like. (Thus, for example, a "rough" surface of the protective layer 13 may be advantageous for subsequent bonding.) A small thickness of the protective layer 13 may be advantageous, for example, for subsequent painting and / or welding.)
  • This sufficient layer quality of the protective layer 13 is preferably achieved by adjusting and, in particular, adjusting the method sequence, individual steps and / or substeps.
  • a steel sheet material 1 which includes the selection of a steel material 10 and / or the selection of a corrosion protection coating 12, influence on the layer quality of the protective layer 13.
  • step III it is possible to influence the layer quality of the protective layer 13 by selecting a forming process and / or at least one accompanying shaping-technical measure.
  • step IV by adjusting at least one process variable of the press hardening process, or an accompanying measure such as e.g. a previous washing, influence on the layer quality of the protective layer 13 are taken.
  • at least one process variable of the press hardening process, or an accompanying measure such as e.g. a previous washing
  • a further optional step V may be required.
  • This further step V can be, for example, a chemical treatment, a precoating, another Heat treatment and / or aging of the heat-treated sheet metal part 3, as explained above.
  • a post-processing of the relevant sheet metal part 3 is optionally provided or optionally also the supply to another use or a separation.
  • a corresponding assignment may e.g. by classifying the layer quality.
  • the layer quality of the protective layer 13 of a sheet metal molding 3 may be e.g. be quantified by at least one determinable parameter, e.g. Information about whether the sheet metal part 3 is subsequently coated and / or available. Also in this regard, reference is made to the above detailed explanations.
  • the finished and heat treated sheet metal part 3 ' may be coated (e.g., painted) and / or joined (e.g., welded) in step VI without removing the protective layer 13, thereby saving effort, energy and cost.
  • This coating and / or joining of the produced sheet metal part 3 ' is not a relevant part of the method according to the invention. Nevertheless, the method according to the invention serves to enable this subsequent coating and / or joining of the sheet metal shaped part 3.
  • a parameter (or several parameters) representing the layer quality and / or a classification of the layer quality of a produced sheet metal part 3 ' is used in a subsequent coating and / or joining in order to achieve this subsequent production step to be able to optimally design the protective layer that has not been removed. This can optionally be done individually for each sheet metal part or for a group or series of sheet metal parts.
  • the inventive method can be carried out once for the production of a heat-treated sheet metal part 3 or repetitive to produce a plurality of such sheet metal parts 3.
  • the individual steps in particular the steps II to V, are carried out as a preset in order to obtain a sheet-metal shaped part 3 with a sufficient layer quality.
  • the execution of at least one step is adjusted during the process flow to obtain a sheet metal part 3 with a sufficient layer quality. This can be done eg in a control loop.
  • the layer quality of a manufactured sheet metal part 3 ' is determined at least randomly and, if appropriate, based on this, the execution of at least one step of a subsequent process sequence is adapted to subsequently obtain a sheet metal part 3 with a sufficient layer quality (good parts).
  • This can also be done in a control loop, for example.
  • the setting or presetting and in particular adjustment can be made manually or automatically.
  • the rectangular frame represents a manufactured sheet metal part 3, which is produced by the process according to the invention.
  • This sheet metal part 3 is determined inter alia by its mechanical material properties, such as hardness, modulus of elasticity, strength and the like, and by the layer quality of the protective layer 13.
  • the left ellipse A represents a set of adjustment and adaptation possibilities in the process sequence with regard to the mechanical material properties of the sheet metal part 3 to be produced.
  • the right ellipse B represents a set of adjustment possibilities in the process sequence with regard to the layer quality of the protective layer 13 to be achieved Production of a good part, with regard to the mechanical material properties and the layer quality of the protective layer 13, however, only those adjustment and adjustment options can be used that are within the intersection C.
