Definitions

  • the invention relates to a method and a device for tempering a steel sheet body.
  • metal sheets or sheet metal parts made of high-strength steel alloys are used, for example, in automobile bodies, which allow for the same strength a design with lower sheet thickness.
  • high-strength sheets sometimes do not have sufficient dimensional flexibility when cold-formed. Therefore, for forming workpieces made of high-strength metal sheets forming processes at elevated temperatures, ie hot forming processes, such as the so-called press hardening used.
  • the sheet metal plates to be reshaped are fully austenitized by heating to a temperature above A c3 (so-called austenitization) and then placed in a pressing tool, formed (so-called hot forming) and cooled in the tool and hardened (so-called direct press hardening).
  • roller pass furnaces are used to heat the sheet steel body during austenitizing.
  • the steel sheet body is placed in the oven and heated relatively slowly during the passage through the Rollenen grasplaüfofen.
  • the residence time of the steel sheet body within the furnace is typically about 5 to 10 minutes.
  • the forming phase of the process is initiated, with the two halves of the tool being closed. By contact with the usually water-cooled tool comes during the rapid cooling of the steel sheet body.
  • the closure of the tool halves must be before cooling. of the steel sheet body to the temperature of the martensitic microstructure transformation (about 400 ° C).
  • the formed component remains in the mold and is further quenched, thereby completing the induced martensitic microstructure transformation and achieving the final properties of the component.
  • the transport between the furnace and the pressing tool represents a fault-prone process step.
  • the temperature of the sheet material can be limited control and control during transport, since the temporal and thermal conditions during the transfer of the steel plate body from the oven into a subsequent forming tool not exactly defined and can be safely reproduced. This can lead to uncontrollable changes in the properties of the sheet material and thus the Umform s.
  • the sheet materials when they come out of the oven a relatively high temperature. This leads to an increased wear on the forming tool.
  • the cycle times required for the hot forming increase, since a relatively long period of time is necessary for the cooling of the sheet material in the tool to a temperature that allows the demoulding.
  • DE 10 2007 009 937 A1 describes a method for tempering a sheet steel body between austenitizing and hot working. Initially, a heating to a predetermined temperature. Subsequently, a cooling takes place through the contact of the steel plate body with two mutually parallel contact plates. Here, the cooling takes place as quickly as possible. If the sheet steel body has been cooled to the desired temperature, the contact plate is removed immediately.
  • the object of the invention is to provide a method and a device for tempering at least one steel sheet body between the austenitizing and the hot forming, by means of which the material properties of the sheet steel body can be adjusted exactly and homogeneously.
  • the steel sheet body located at austenitizing temperature is fixed in position, at least one first contact plate is brought into contact with at least one first surface portion of the steel sheet body and at least one second contact plate with at least one second Surface portion of the steel sheet body brought into contact.
  • the contact plates are flat substantially or completely formed according to the contour of the surface portions of the sheet steel body and arranged in the state of contacting with the sheet steel body substantially parallel to each other. At least one contact plate has during the contacting of the steel sheet body with respect to the steel sheet body lower temperature.
  • the temperature in at least a portion of the at least one lower temperature contact plate is controlled by a temperature control device during contacting of the steel sheet body with the contact plates.
  • the temperature control of the contact plate with a lower temperature is carried out by an at least one of the contact plates in connection standing as an inductive or conductive heat source formed energy source, wherein the at least one heat source is integrated in one of the contact plates.
  • Under a sheet steel body here are both single substantially planar-shaped sheets and steel blanks, as well as three-dimensionally shaped sheet metal parts made of steel and also components that are composed of several such sheets understood.
  • the austenitizing temperature is understood to mean the temperature above A c3 at which the steel sheet body was austenitized.
  • the method according to the invention can be used variably.

However, it may also be an intermediate layer, such as a contact agent, which improves the temperature balance between the contact plate and sheet steel body, be present.
  • the area associated with the contact plates surface portions can both extend over large parts of the sheet steel body or completely cover this and form only small, localized areas of the sheet steel body. If only locally limited areas are connected to the contact plates, a local thermal treatment of the steel sheet body can be carried out.
  • a sheet metal plate made of a steel of composition 22MnB5 and having an AlSi10 coating as steel sheet body located at austenitizing temperature is fixed between a first contact plate and a second contact plate.
  • the contact plates have a temperature between 400 ° C and 600 ° C. After the sheet steel body has been contacted by the contact plates for a period of, for example, 10 seconds to 120 seconds, it is placed in a forming tool and hot worked.
