Definitions

  • Such annealing devices are well known and are commonly used to heat pre-treat metallic workpieces to obtain defined workpiece characteristics.
  • the strength of the aluminum workpieces can be temporarily reduced and thus the malleability of the aluminum workpieces can be improved by a previous annealing process.
  • the workpiece is usually heated to a certain temperature, then solution-annealed by holding the workpiece to a certain holding temperature and finally cooled.
  • Solution annealing serves to produce the desired chemical and physical processes in the workpiece caused by the holding temperature.
  • the workpieces are punched, pressed, cut or the like depending on the application in any way.
  • the stacking and transport mechanism has at least one lifting element for lifting a lowermost goods carrier located in the compensation device in the vertical direction, wherein the lever element preferably comprises a bolt protruding into the compensation device in a vertical direction.
  • the metal plates are thus preferably only in the area of support means on the goods carriers, so that the most homogeneous temperature distribution in the interior of the metal plates is not affected by the goods carrier and thus only a small or insignificant distortion of the metal plates.
  • the annealing device has a return device for returning the goods carriers from the outlet opening to the inlet opening outside the compensating device.
  • the product carriers are preferably returned automatically to the entrance opening and are then ready to receive further coming from the warm-up metal plates.
  • the cooling device has a cutting device, which preferably comprises cutting blades which adjoin the cooling pistons, wherein the first and second cooling pistons are movable together relative to the cutting blades.
  • the metal plates can thus be simultaneously trimmed in the cooling device to a size which is advantageous for the further treatment.
  • the metal plates are cooled, cut and oiled in only a single stroke of the cooling dies, so that advantageously a high throughput of metal plates is achieved.
  • a further subject of the present invention is a method for annealing metal plates with an annealing device according to one of the preceding claims, wherein in a first method step metal plates are warmed up by means of the heating device and in a second method step the heated metal plates are held on a substantially constant surface by means of the equalizing device Be kept temperature, wherein the metal plates stacked by means of the stacking and transport device in the balancing device over each other and along the vertical direction through the Aus- same device to be transported.
  • an efficient heat treatment of the metal plates is achieved with reduced space requirement and high throughput.
  • a metal plate is placed on a goods carrier, wherein in a second sub-step of the second process step, the goods carrier is introduced together with the metal plate through an input opening in the compensating device, wherein
  • the product carrier is transported together with the metal plate along the vertical direction through the compensating device, wherein a further product carrier is introduced together with a further metal carrier disposed on the other metal plate through the input opening in the balancing device and wherein a third sub-step of the second process step of the goods carrier is issued together with the metal plate through an exit opening, wherein the further goods carrier together with the we iteren metal plate along the vertical direction is transported by the balancing device.
  • the metal plates are thus automatically stacked in the balancing device and simultaneously moved continuously through the compensating device.
  • the goods carriers are preferably returned in a fourth process step from the exit opening by means of a return device outside the compensating device
  • the input flap 31 and the outlet flap 32 are preferably each controlled in such a way that they respectively open or close sequentially one after the other. In other words, at no time are both the inlet flap 31, and the outlet flap 32 open, so that the heat loss in the annealing vessel 4 'through the input and output ports 6, 7 is kept as low as possible.
  • the ejection slide is actuated in each case during the downward movement or temporally before the lifting movement of the lifting elements 50.
  • the stack height in the annealing vessel 4 ' preferably depends on the respective holding and / or cycle time.
  • a detailed view of the product carriers 8 is shown in FIG. 4 shows a schematic sectional view, as well as a schematic plan view of a goods carrier 8 of the glow device 1 according to the exemplary embodiment of the present invention.
  • the product carrier 8 is produced by way of example from a embossing plate. In the sectional view, it can be seen that the metal plate 2 rests loosely on support devices 10 of the goods carrier 2. These support means 10 are formed by introduced into the embossing plate beads.
  • the goods carriers 8 are optionally provided with recesses 36. It is conceivable that the product carrier 8 is designed such that it can be heated inductively and / or has a comparatively high heat capacity. In this way, the product carrier 8 can be preheated and / or act as a heat storage.

Abstract

L'invention concerne un dispositif de recuit pour recuire des plaques de métal, ce dispositif comprenant un dispositif de chauffe pour chauffer les plaques de métal et un dispositif d'égalisation pour maintenir les plaques de métal à une température sensiblement constante. Selon l'invention, le dispositif d'égalisation comprend un mécanisme d'empilement et de transport pour empiler les plaques de métal chauffées par le dispositif de chauffe dans le dispositif d'égalisation et pour transporter les plaques de métal chauffées dans une direction verticale, perpendiculaire à leur plan principal, à travers le dispositif d'égalisation.
