Definitions

  • the present invention relates to a system for producing a hot-hardened sheet-like workpiece, in particular a body part.
  • the workpiece is heated at least locally to a minimum temperature before the (possibly last) deformation.
  • the subsequent shaping then takes place in a forming press, the tool of which is tempered at least locally, i. H. in particular is cooled.
  • the minimum temperature to which the workpiece is heated before the forming step depends largely on the respective material; often the temperature is in the range of incipient red heat. An annealing furnace is therefore often used to heat the workpiece.
  • the DE 102010049205 A1 discloses a hot forming line for the hot forming of sheet-like material and an associated hot forming process, with at least one heating station (e.g. a continuous furnace) and at least one hot forming device being provided.
  • the hot forming line according to this document is characterized in that a hot rolling device is arranged after the at least one heating station and in front of the hot forming device. Removal and feed devices are arranged between the individual stations (storage, heating station, hot rolling station and hot forming station).
  • the DE 102010035339 A1 discloses a method for the production of at least partially hardened molded components such as structural or body components of motor vehicles, a blank made of unhardened, hot-formable sheet steel down to a temperature in the specific austenitizing temperature range of the material is heated and then hot-formed into a molded part in the mold space of a press tool. The molded component is removed from the press tool after a holding time of 0.1 seconds to a maximum of 3 seconds and is cooled and hardened by at least partial contact with a coolant.
  • a system suitable and intended for carrying out this method comprising a furnace, a pressing tool with an upper tool, a lower tool and a cooling-heating circuit, a coolant bath, a first manipulator arranged between the furnace and the pressing tool, a second manipulator arranged between the pressing tool and the coolant bath Manipulator and a third manipulator connected downstream of the coolant bath.
  • the one relating to a transfer press line DE 19808974 A1 discloses a method and an apparatus for transporting molded parts between several stages of a forming plant. By increasing the simultaneity of movement phases of the removal and supply device, the handling time should be reduced and the output of the forming system increased.
  • the molded parts are fed into and removed from a tool stage in two different superimposed transport levels, with the supply and removal between the adjacent tool stages operating with phase shift alternating from an upper or lower to a lower or upper transport level in the direction of passage , the upper tool is included alternately between the adjacent tool levels in the transport from a lower or upper to an upper or lower transport level and for this purpose the slides assigned to adjacent tool levels can be moved longitudinally in opposite directions in two transport levels on a frame-mounted running rail, in the area of the tool levels at times stand on top of each other and are connected to lifting modules for vertical lifting movement of the transport traverses fastened via quick couplings.
  • the present invention has set itself the task of providing a system for the production of a hot-hardened sheet-shaped workpiece, with which hardened sheet-metal parts that meet high quality requirements can be produced in a particularly efficient manner, whereby particularly relevant aspects of efficient production are energetic efficiency and production-economical efficiency (e.g. B. short cycle times).
  • the above object is achieved according to the present invention by a system for producing a heat-hardened sheet-like workpiece, which is characterized by the following synergetically interacting features:
  • the system for producing a hot-hardened sheet-like workpiece comprises an input magazine or some other input storage device for storing a plurality of unhardened sheet metal blanks, an annealing furnace connected downstream of the input storage device, through which the sheet metal blanks can preferably be moved continuously, with a workpiece inlet and a workpiece outlet, a between the input storage and the workpiece inlet of the annealing furnace, a workpiece feed device arranged downstream of the annealing furnace, vertically openable and closable, temperature-controlled hot-hardening forming press, a workpiece transfer device arranged between the workpiece outlet of the annealing furnace and the hot-hardening forming press with a workpiece transfer device into the open hot-hardening forming press and a loader that can be moved out of this, a cooling station connected downstream
  • the drivers fix the hot-hardened workpiece on the upper tool in a position raised therefrom, and in the open hot-hardening forming press the unloader and the loader are located below the hot-hardened workpiece held by the drivers on the upper tool.
  • the design of the workpiece feed device and the workpiece removal device such that the loader (working at a first height in the open hot-hardening forming press) and the loader (in the open hot-hardening forming press at a height that differs from the first second height working) unloaders are located at the same time in the open hot-hardening forming press and there simultaneously the steps assigned to them, namely the transfer of a blank that has yet to be hot-hardened in the annealing furnace to the hot-hardening forming press on the one hand and the removal of an already hot-stamping workpiece from the hot-hardening forming press on the other hand, can perform.
  • the drivers for the hot-hardened workpiece which are arranged on the (movable or moved) upper tool of the hot-hardening forming press, when the hot-hardening forming press is opened, lift the workpiece when the press is opened after the hot-hardening process, to the extent that in the space Below the workpiece (and above the fixed lower tool) there is space for both the unloader, on which the heat-hardened workpiece can be deposited, and the loader, which can deposit the blank in the lower tool. Since the heat-hardened workpiece can only be transferred to the unloader by placing the workpiece on the latter (e.g.
  • gripping tongs or comparable clamping devices can be used on the unloader, which damage the surface of the finished, thermoformed workpiece could be dispensed with; In other words, the finished formed workpiece can be handled in a particularly gentle manner.
  • the drivers explained above are designed so that they fix the heat-hardened workpiece in a position slightly raised from the upper tool.
  • the hot-hardening forming press when the hot-hardening forming press is opened, the workpiece (adhering to the lower tool) can be lifted slightly from the upper tool until it is held by the drivers and then out of the lower tool by the latter is lifted.
  • the reverse can also be done when the hot-hardening forming press begins to open the workpiece initially stick to the upper tool. Active support for lifting or separating the workpiece from the respective tool part is also possible in each case, in particular by means of ejector structures.
  • the loader and unloader can work at the same level, in particular if at least one of the units (loading unit or unloading unit) is height-adjustable or has a movement path with changing height.
  • the possibility of specifying freely programmable sequences of movements by means of a corresponding control and height and length adjustment drives operated by this allows a particularly high degree of flexibility and optimization of the process management.
  • the unloader in the open hot-hardening forming press
  • the loader is arranged above the loader.
  • the hot-hardening forming press open, the sheet metal part which was hot-hardened in the previous forming step is removed from the hot-hardening forming press at a second level, which is above the first level, at which (at the same time) the blank to be hot-hardened in the next forming step is inserted into the hot-hardening forming press.
  • the difference in height between the feed level (loader) and removal level (unloader) can be used for gravity-assisted transport of the workpiece in the continuous production process - based on the workpiece flow direction - above and below the hot-hardening forming press.
  • the hot-hardening forming press also fulfills the function of a "workpiece lifter".
  • the loader can be moved linearly by means of a loader drive relative to further components of the workpiece transfer device - at least on part of its complete path of movement.
  • the unloader is preferably linearly movable with respect to further components of the workpiece removal device by means of an unloader drive - at least on part of its complete path of movement.
  • the linear mobility allows particularly favorable spatial configurations of the system according to the invention for producing a heat-hardened sheet-like workpiece. Under certain spatial conditions, however, a different configuration of the system can also prove to be advantageous, for example in that the loader and / or the unloader can be pivoted with respect to other components of the workpiece transfer device or the workpiece removal device.
  • the loader drive and the unloader drive are independent of one another.
  • the loader drive and the unloader drive can in this sense be freely programmable and can be activated by a machine control. This enables an ideal adaptation of the individual steps of the process running in the system in the sense of an optimization of production quality and process efficiency.
  • Yet another preferred development of the present invention is characterized in that the workpiece transfer device and the workpiece removal device are arranged on different sides of the hot-hardening forming press.
  • the workpiece transfer device and the workpiece removal device can be arranged opposite one another in relation to the hot-hardening forming press. This accommodates the use of the height difference between the feed level (loader) and removal level (unloader), which has already been worked out above, for gravity-assisted transport of the workpiece in the direction of the ongoing production process.
  • the cooling station used within the scope of the invention can be designed very differently depending on the individual process. For example, magazine-like cooling stores as well as discharge belts or similar transport systems come into consideration. According to a preferred development of the invention, the cooling station and the annealing furnace are arranged opposite one another in relation to the hot-hardening forming press. This, in turn, allows a configuration of the system according to the invention for the production of a heat-hardened sheet-shaped workpiece which is particularly favorable under typical spatial conditions.
  • this preferably has a coolant supply via which coolant (e.g. water) is introduced into the upper tool and / or the lower tool. Within the upper or lower tool, it is then guided to the areas of the tool to be cooled by means of corresponding channels.
  • coolant e.g. water
  • the annealing furnace - designed for continuous movement of the blanks to be heated -
  • different designs and configurations are basically suitable for implementing the present invention.
  • the invention can be implemented with particular advantage with such annealing furnaces in which the workpiece inlet and workpiece outlet are arranged opposite one another so that the blank to be heated is moved straight through the corresponding annealing furnace without changing the direction of movement.
  • the workpiece transfer device preferably has a stop station.
  • the manufacturing process is controlled (via the dwell time at the stop station) in such a way that the heated blank cools down to its optimal temperature for the subsequent hot hardening during its stay at the stop station, which, conversely, means that the blank is preferably above the optimal temperature in the annealing furnace Heat curing temperature is heated beyond.
  • the stop station particularly preferably has workpiece centering. The heated blank rests against this while it is at the stop station, so that it can then be reliably gripped by the loader.
  • sheet metal blanks 1 which - with simultaneous final deformation into a body part 2 - are to be subjected to hot hardening, are stored in an input storage 4 designed as an input magazine 3.
  • the workpiece feed device 7 comprises a converter 8 for an individual sheet metal blank 1 as well as one loaded by this , here for example designed as a roller conveyor 9 conveyor 10. This moves the sheet metal blank 1 deposited on it through the workpiece inlet 5 of the annealing furnace 6 into this.
  • the annealing furnace 6 is a continuous furnace with a workpiece outlet 11 arranged opposite the workpiece inlet 5.
  • the conveyor 10 thus extends through the annealing furnace 6, possibly divided into several segments operating at different speeds.
  • the sheet metal blank 1 leaves it through the workpiece outlet 11 and arrives at a workpiece transfer device 12.
  • This comprises a stop station 13 at which the sheet metal blank 1 is stopped by several stops 14, and a loading unit 15, which enables the subsequent insertion of the Sheet metal blank 1 in a hot-hardening forming press 19 fitted with a temperature-controlled tool 18 which is locally cooled via cooling channels 17 connected to coolant supply lines 16.
  • the loading unit 15 comprises a loader 21, which is mounted horizontally on a base 20 and can be moved by means of a loader drive, with grippers 22 arranged thereon.
  • the stop station 13 comprises a workpiece centering device (not shown) which is used for exact positioning of the sheet metal to be taken over by the loader 21 Blank 1 ensures that it can be reliably gripped at predetermined points by the grippers 22 of the loader 21.
  • the sheet metal blank 1 grasped by the grippers 22 of the loader 21 is then moved into the open hot-hardening forming press 19 by horizontally displacing the loader 21, specifically at a level just above the lower tool 23.
  • the sheet metal blank 1 is then placed on the lower tool 23. And then the loader 21 is withdrawn, i.e. H. move out of the hot-hardening forming press 19.
  • the hot hardening forming press 19 is then closed, that is to say the upper tool 24 is lowered onto the lower tool 23. After the process-related predetermined pressing time, the hot-hardening forming press 19 opens.
  • the hardened body part 2 which has its final shape, is slightly attached to and from the pressing surface of the lower tool at the beginning of the opening of the hot-hardening forming press 19 from an ejector structure 25 on the lower tool 23 23 lifted off.
  • the hot-hardening forming press 19 is opened further, the hardened body part 2 is raised further together with the upper tool 24 by drivers 26 arranged on the upper tool 24.
  • a workpiece removal device 28 comprising an unloading unit 27 is arranged on the side of the hot-hardening forming press 19 opposite the workpiece transfer device 12. If the hot-hardening forming press 19 is completely open, an unloader 30, which is mounted displaceably on a base 29 of the unloading unit 27 and can be moved by means of an unloader drive independent of the loader drive, is moved into the open hot-hardening forming press 19. In fact, it is moved horizontally until it is just below the hardened body part 2, which is still held by the drivers 26 of the upper tool 24.
  • a further sheet metal blank 1 to be hot-hardened is introduced into the hot-hardening forming press 19 by means of the loader 21, which operates at a lower level than the unloader 30, just as has been described above. While the fully formed and hardened body part 2 is deposited on the unloader 30 by opening the driver 26 arranged on the upper tool 24, the next sheet metal blank 1 to be hot-hardened is placed on the lower tool 23 of the hot-hardening forming press 19 by opening the gripper 22 of the loader 21 filed. Subsequently, both the loader 21 and the unloader 30 are withdrawn from the hot-hardening forming press 19 so that the latter can be closed - for hot-hardening forming the next sheet metal blank 1 (see above).
  • the hot-hardening forming press 19 is followed by a cooling station 32 for the finished formed and hardened body part 2, which includes, for example, a discharge belt 31.
  • the body part 2 is set down on the discharge belt 31 by means of the unloading unit 27.
  • FIG. 8 the same operating point of the process like Fig. 4 , only offset in one full cycle. In the ongoing production, as this is expressed, the steps are repeated cyclically.
