Definitions

  • the invention relates to a temperature control station for the partial heat treatment of a metallic component, a device for the heat treatment of a metallic component and the use of at least one tangential nozzle in a temperature control station for the partial heat treatment of a metallic component.
  • the invention can be used in particular in connection with a press hardening line in which a press hardening tool is arranged downstream of a continuous furnace, in particular a roller hearth furnace.
  • the upper and lower end areas of the B-pillar should have a comparatively low strength in order to be able to absorb deformation energy during a side impact on the one hand and during a side impact on the other the assembly of the B-pillar to enable simple connectivity with other body components.
  • the hardened component In order to form such a partially hardened body component, it is necessary for the hardened component to have different strength properties in the subregions.
  • the tempering station is provided and set up to set different temperatures in the subareas of the component, which is initially uniformly heated, so that different strength properties are set in the subareas during the subsequent press hardening.
  • Optimal cycle times which play an important role in the vehicle industry in particular, can be achieved here in particular if the components oven, temperature control station and press hardening tool are arranged one behind the other.
  • one or more specific sub-areas of the component which should have a higher ductility or lower strength in the hardened component than other, hardened sub-areas of the component, are specifically cooled in the temperature control station, in particular while the others, parts of the component to be hardened are kept at a high temperature.
  • partitions which are also referred to as bulkheads, are regularly used, which are arranged next to the nozzles in the temperature control station and which are provided and set up for the (thermal) delimitation of the respective sub-areas of different strength.
  • the partition walls can even touch the component, if necessary, but a gap, which is to be kept as small as possible, must regularly be provided between the lower end of the respective partition and the component.
  • the gap between the partition and the component is not small enough to reliably prevent a possible leakage of cold air to the hotter and hot part of the component. This leads to an unwanted blurring in the transition area, as a result of which the transition area is usually larger than necessary or desired.
  • warping of the hot component or insufficiently precise positioning of the component can lead to undesired enlargements of the gap.
  • the automotive industry is increasingly placing great importance on the smallest possible transition areas so that the subsequent crash behavior can be better mapped in the previous design, in particular in the previous simulation of the crash behavior. Therefore, there is an increasing effort to be able to set the transition areas as precisely and as small as possible, which is made more difficult in particular by the leakage flows between the partition and the component that have occurred in previous temperature control stations.
  • Thermal treatment methods are from the DE 10 2015 112 293 A1 and DE 10 2012 021 576 A1 known.
  • a temperature control station and a device for heat treatment of a metallic component are to be specified, which it allow a transition area between differently heat-treated sub-areas of the component to be set as reliably and / or exactly as possible, in particular as small as possible.
  • the temperature control station and the device should in particular allow contact of the component with a partition wall for (thermal) delimitation of the differently temperature-controlled subregions of the component is no longer necessary.
  • a temperature control station for the partial heat treatment of a metallic component has at least one (horizontal) processing plane arranged in the temperature control station, in which the component can be arranged, and at least one nozzle, which is oriented towards the processing plane and for discharging a fluid flow for cooling at least a first sub-area of the component is provided and set up.
  • the at least one nozzle is a tangential nozzle.
  • the tangential nozzle is characterized in particular by the fact that it generates and / or discharges a fluid flow at at least one nozzle outlet which has at least one directional component or a streamline that is essentially tangential and / or parallel to the processing plane and / or a surface of the component .
  • the terms "essentially tangential” and “im “Essentially parallel” here includes in particular deviations from the ideal shape ("tangential” or “parallel") in the range from -10 ° to + 20 ° [degrees], preferably 0 ° to 20 °.
  • the tangential nozzle preferably generates a horizontal flow downstream of its nozzle outlet.
  • a plane in which a nozzle outlet cross-section or an opening of a nozzle outlet of the tangential nozzle is located can enclose an angle of 0 ° to 135 ° [degrees], preferably 0 ° to 75 ° and in particular 20 ° to 75 ° with the (horizontal) processing plane .
  • the tangential nozzle contributes in particular to directing the air flow in such a way that an air pulse in the direction of a second partial area of the component is suppressed at the nozzle outlet. It is particularly preferred if a nozzle outlet or a nozzle outlet opening of the tangential nozzle points or is directed towards the first partial area of the component and / or away from a second partial area of the component.
  • the solution presented here advantageously allows a type of “aerodynamic seal” to be provided in the direction of the second partial area of the component. This helps to ensure that essentially no leakage of the fluid flow reaches the second sub-area of the component, which should change its high component temperature as little or as little as possible during the cooling of the first sub-area in the temperature control station for the purpose of hardening the second sub-area.
  • very sharply delimited transition areas can be represented in an advantageous manner.
  • a transition area that can be achieved by means of the solution presented here lies approximately in the range from 1 mm to 60 mm [millimeters].
  • the size, in particular the width of the transition area is mainly (only) determined by the physically unavoidable heat conduction in the component.
  • soft outer flanges can be easily produced on hard components.
  • the metallic component (to be treated by means of the temperature control station) is preferably a metallic blank, a sheet steel or an at least partially preformed semi-finished product.
  • the metallic component is preferably made with or made of a (hardenable) steel, for example a boron (manganese) steel, e.g. B. with the designation 22MnB5 formed.
  • the metallic component is further preferably provided or precoated at least to a large extent with a (metallic) coating.
  • the metallic coating can be, for example, a (primarily) zinc-containing coating or a (primarily) aluminum and / or silicon-containing coating, in particular a so-called aluminum / silicon (Al / Si) coating.
  • the metallic component can (alternatively) also be formed with or from aluminum or with or from an aluminum alloy.
  • the temperature control station is preferably arranged downstream of a first furnace and / or upstream of a second furnace.
  • a processing plane in which the component can be or is arranged is arranged in the temperature control station.
  • the processing level here refers in particular to the level into which the component can be brought for treatment in the temperature control station and / or in which the component is arranged and / or fixable during the treatment in the temperature control station.
  • the working plane is preferably aligned essentially horizontally.
  • the temperature control station has at least one nozzle.
  • the nozzle is oriented towards the working plane.
  • the nozzle for discharging a fluid stream for cooling at least a first sub-area of the component is provided and set up, in particular so that a temperature difference between the at least one first (more ductile in the finished component) sub-area and at least one second (in the finished component in Compared to this, the harder) partial area of the component is adjustable.
  • a plurality of nozzles is preferably provided, the nozzles particularly preferably being arranged in a nozzle field. When a plurality of nozzles are provided, at least one of the nozzles is a tangential nozzle.
  • the fluid flow is preferably formed with a cooling fluid.
  • the cooling fluid can be formed with a gas, for example nitrogen, or with a gas mixture, in particular air.
  • the cooling fluid can be formed with a gas-liquid mixture, for example an air-water mixture.
  • the temperature control station can have one or more further nozzles which have a different, in particular structurally simpler, nozzle geometry.
  • at least one further nozzle can be provided which has or forms, in particular surrounds, at least one nozzle channel running essentially perpendicular to the processing plane.
  • the further nozzle is preferably arranged next to the (tangential) nozzle in the temperature control station, but in particular not between the (tangential) nozzle and a partition.
  • the further nozzle and the (tangential) nozzle can be held at the same height within the temperature control station and / or above the processing plane.
  • the at least one further nozzle is preferably designed in the manner of a shower head. In other words, this means in particular that the at least one further nozzle has a multiplicity of outlet openings on an underside pointing towards the processing plane.
  • a combination of (tangential) nozzles and further nozzles, each designed in the manner of a shower is particularly advantageous in the event that large-area first partial areas of the component are to be cooled. It is particularly advantageous if the (tangential) nozzles are arranged in the area of a partition and the further nozzles (in comparison to this) are arranged more towards the center of the first partial area of the component to be cooled. If the deformation of the component due to residual stress increases over large areas so that with pure horizontal flow (from the tangential nozzles) behind the elevations, dead areas with a lower flow velocity can arise, this leads to slower cooling in places. Therefore, large areas should (also) be flown vertically.

(Immediately) after the fluid flow has been deflected towards the first sub-area, the fluid flow can leave the at least one nozzle essentially tangentially and / or parallel to the processing plane and / or a surface of the first sub-area of the component.
  • the nozzle geometry of the at least one nozzle is preferably designed in such a way that at least one component of the fluid flow, at least one (central) streamline of the fluid flow or even the entire fluid flow flowing through the respective nozzle flows through the nozzle (initially) in a first direction, then is deflected and then flows through the nozzle in a second direction.

  • the at least one nozzle is particularly preferably cranked in such a way that a nozzle outlet of the at least one nozzle has a smaller (horizontal) distance from the partition than a nozzle inlet of the at least one nozzle.
  • the nozzle outlet can be arranged very close to or even at least partially below the partition and thus very close to the transition area to be generated, while still being sufficient remaining space between the nozzle inlet and the partition wall for thermal insulation attached to the partition wall.
