Definitions

  • the invention relates to a furnace system and a method for the targeted component zone-specific heat treatment of sheet metal components.
  • the prior art describes corresponding methods and devices. These methods use partially heated tools, wherein a portion of the component is cooled above the martensite quenching rate. As usual, the remainder of the component is cooled abruptly and forms martensite.
  • EP 2 012 948 a forming tool for press hardening and tempered forming of a board made of higher and / or very high strength steels with means for temperature control of the forming tool and a method for press hardening and tempered forming of blanks of higher and / or higher strength steels in which the board is heated prior to forming is and then hot or semi-hot formed in a forming tool, wherein the forming tool has means for temperature control.
  • a plurality of controllable means for temperature control are provided in the forming tool, whereby a plurality of temperature zones can be defined, wherein at least the contact surfaces of the Umformwerkmaschinemaschinemaschinemaschine used for forming individual temperature zones are assigned.
  • the document WO 2009/113 938 describes a press hardening process that can achieve soft sections in the finished product by reducing the cooling rate of these sections of material. This reduces the martensite in these areas and consequently increases the elongation at break of these areas.
  • the component is heated in a two-zone oven in the soft range to a temperature below the material-dependent AC3 temperature, the area to be cured, however, to a temperature above the AC3 temperature.
  • the disadvantage of this process is that the oven can only be used to a limited extent and can no longer serve as a universal oven. Thus, this method loses economy.
  • Another disadvantage is that the separation of the areas usually can not be permanently realized with sufficient accuracy.
  • more than two different zones are not meaningfully achievable.
  • it is necessary to maintain the temperature at about 950 ° C for about 300 seconds to allow diffusion of the coating into the base material. At lower temperatures, this process takes much longer and the economy of the entire system is reduced.
  • the object of the invention is therefore to provide a furnace system and a method for the targeted heat treatment of sheet metal components, which avoids the disadvantages described above.
  • the furnace system according to the invention is suitable for partially heating components made of sheet steel to a temperature above the AC3 temperature.
  • the furnace system includes a common, universal production furnace for heating the steel sheet parts to a temperature close to but below the AC3 temperature, the furnace system further comprising a profiling furnace having at least one plane.
  • the at least one level has an upper and a lower part, as well as a product-specific intermediate flange introduced into a corresponding receptacle, the product-specific intermediate flange being designed to give the component a predetermined temperature profile with temperatures above the AC3 temperature for areas to be hardened and below Apply AC3 temperature for softer areas.
  • the furnace system further has a positioning system on which the component can be stored in a defined position after heating in the production furnace and / or after heating in the profiling furnace. This ensures that the component is in a predefined position after heating in the production furnace or after partial heating in the profiling furnace.
  • the component can subsequently be inserted into a predefined position in the profiling oven or a press for the subsequent form hardening process. The more accurately the insertion position of the component can be maintained, the less trimming the finished, hard sheet metal part is required.
  • the product-specific intermediate flange has means for actively cooling individual areas.
  • the cooling is designed as water cooling.
  • the product-specific intermediate flange has means for heating individual regions, wherein in a particular embodiment, this is electrical heaters.
  • this is electrical heaters.
  • the method according to the invention provides for heating the components in the production furnace only to a temperature below the AC3 temperature and for introducing the heat for heating defined regions to a temperature above the AC3 temperature in a later process step in the profiling furnace, this is a very accurate Temperature control in the production furnace is not required, so that the disadvantage of the lower controllability of gas burners over that of electric heaters in favor of the economy for the cheaper energy gas can be accepted.
  • the furnace system to a production furnace, which has a continuous furnace via a transport system for passing the components through the production furnace.
  • the cycle time for the heating of the components can thus be maintained at the level of conventional heating furnaces for the mold hardening process. If the downstream process step of imprinting a temperature profile on the component cycle time is determining, so that the Cycle time for the entire process threatens to extend, a profiling furnace can be used with multiple levels, in which the components are heated partially or partially parallel partially further. The parallel use of several Profilieröfen is conceivable.
  • the profiling oven in an advantageous embodiment means for temperature control in the closed loop.
  • advantageously more than one control loop can be provided.
  • the furnace system further has a handling system for handling the components.
  • the handling system can place the components specifically and quickly in the positioning system, remove them again from the positioning system and insert them into the product-specific intermediate flange in the profiling furnace and remove them again.
  • the handling system can then insert the components in a press tool for subsequent hardening.
  • a handling system executes the movements in defined and reproducible times, so that the components can be inserted with minimal temperature tolerances in the press tool for mold hardening, which has proven to be advantageous for component quality.
  • Discharge of the component provided with a temperature profile from the profiling oven Discharge of the component provided with a temperature profile from the profiling oven.
  • gas burners which can be used as an energy source, for example, natural gas.
  • the introduction of the positioned component takes place in a defined position in the profiling furnace by a handling system.
  • the application of a temperature profile is controlled on the component in the profiling oven via a closed loop.
  • tightest temperature tolerances can be realized on the component, which has a positive effect on the quality of the form-hardened component. It has proven to be advantageous if to apply the temperature profile to be cured areas of the component are heated via a product-specific intermediate flange targeted to a temperature above the AC3 temperature, while other areas that should have a higher elasticity in the finished part, at a temperature be kept below the AC3 temperature.
  • Fig. 1 shows a furnace system according to the invention in a plan view.
  • a first robot 61 positions a component 5 on a roller belt which transports the component 5 through the production furnace 10.
  • the production furnace 10 is a conventional general-purpose furnace, which is heated with natural gas burners 9 to a temperature below the AC3 temperature of the respective component material.
  • the transport speed of the components 5 through the production furnace 10 is selected so that the components 5 almost assume the temperature prevailing in the production furnace 10.
  • a positioning system 20 In the transport direction behind the production furnace 10 is a positioning system 20 that brings each component 5 in a defined lying position.
  • a handling system 22 receives the component 5 and brings it into a defined position in the profiling oven 40.
  • the intermediate flange 45 has, on the one hand, regions with heaters 46 and, on the other hand, regions 48, which can be cooled.
  • regions with heaters 46 and, on the other hand regions 48, which can be cooled.
  • a cooling medium such as water or oil
  • heaters 46 all known heaters such as electric heating cartridges or electric surface heaters can be used. Electric heaters have the advantage that they can be regulated very accurately and quickly. With the heater 46, the areas 30, which are to be particularly hard after a subsequent form hardening process, heated to a temperature above the AC3 temperature. Other areas 50, which should have a higher elongation at break after the subsequent form hardening process, are at a temperature below that by the targeted cooling 48 of these areas AC3 temperature maintained. The temperature control takes place in at least one closed loop. After the dwell time required for heating the areas 30 to the desired temperature above the AC3 temperature, the component 5, which is now provided with a temperature profile, is discharged from the profiling oven 40 by means of the handling system 22.
  • the handling system 22 is executed in the illustrated embodiment as a rake. However, all other suitable handling systems can also be used.
  • the handling system 22 places the component 5 again on the positioning system 20. However, it is also conceivable to deposit the component 5 after impressing a temperature profile on another transfer station. A second robot 60 then takes over the component 5 in order to insert it into the tool 70 of a press for molding. Usually, however, the component 5 can be inserted directly into the press tool 70 without repositioning, since no relative movement and thus no reorientation of the component 5 takes place in the profiling oven 40.
  • Fig. 2 shows the profiling oven 40 in a detailed view as a plan view.
  • a further component 5 is located in the profiling oven 40.
  • Areas 30 of the component 5, which should be particularly hard after the mold hardening process, are located on areas of the product-specific intermediate flange 45, which can be selectively heated by heaters 46. It is an electrical heating element, which is supplied via terminals 47 with electrical energy, which is provided by a control means (not shown).
  • Another region 50 of the component 5, which after the mold hardening process is to have a greater elongation at break than the hard region 30, is located at a region 48 of the product-specific intermediate flange 45, which can be cooled in a targeted manner. For this purpose, cooling medium is conducted through the connections 49 into the region 48.
  • Fig. 3 is the section AA off Fig. 2 through the profiling oven 40.
  • the Profiolierofen 40 has an upper part 41 and a lower part 42, and a receptacle 44 for a product-specific intermediate flange 45 and the product-specific intermediate flange 45 itself.
  • heaters 46 can be seen, which are powered via terminals 47 with energy. This can do that
  • Component 5 are selectively heated in the range 30 to a temperature above the AC3 temperature. Furthermore, the handling system 22, which is located in front of the profiling furnace 40 can be seen. The arrows indicate that the handling system 22 can move a component 5 vertically and horizontally so that a component 5 (not shown) on the positioning system 20 can be inserted by means of the handling system 22 into the product-specific intermediate flange 45 within the profiling furnace 40.
