Definitions

  • the invention relates to a device for producing corrugated sheets with plane-parallel outer edge surfaces with a hydraulic or mechanical press with at least one hydraulic or Pneumatic cylinder and at least one upper and lower embossing tool, the are provided with embossing tool end pieces at their opposite ends.
  • Such a device is described for example in DE-A-20 29 528, in which also a the associated process is described, in which beads are first formed into a sheet, which extend in their longitudinal directions to the edge areas of the sheet. In a second However, the end areas of the respective beads are then squeezed and deformed back towards the sheet metal exit plane, but do not reach it all.
  • These measures create z-shaped pinch folds, so that between each two such pinch folds of a bead in the area of the outer edge surfaces outside the sheet metal exit plane remains, which is undesirable and the task of the application Invention can not meet.
  • a capillarity forms on the pinch folds, through which air and moisture can penetrate into the pinch folds, so that use such sheets for the manufacture z. B. is excluded from refrigerated containers. These are on it instructed to have airtight outer walls to keep out moisture Effect of the insulating layer destroyed within a short time, reliably preventing it.
  • the object of the present invention is therefore to provide a device of the type mentioned in the introduction create, with the help of corrugated sheets can be produced, in which the illustrated Advantages used and the disadvantages also shown can be avoided.
  • the invention further relates to a method for producing corrugated sheets with plane-parallel Outer edge surfaces in a hydraulic or mechanical press, with top and bottom Embossing tools open beads are molded into a sheet, including each a bead associated with outer edge surfaces.
  • each associated with a bead Outer edge surfaces then again in their sheet metal starting plane before the molding of the bead be reshaped while the sheet metal is between the upper and lower embossing tools the press is clamped.
  • the device essentially consists of a hydraulic or mechanical press (1) with at least one hydraulic or pneumatic cylinder (2) and at least one upper one Embossing tool (3) and a lower embossing product (4), each facing away from one another Ends 5 with an upper embossing tool end piece 6 and a lower embossing tool end piece 7 are provided. 6 and 7 are integrated in the embossing tool end pieces Hydraulic or pneumatic cylinders 8, 9 are provided, which are provided with contour stamps 10, 11.
  • the contour stamp 10 has in the upper embossing tool end piece 6 the same contour 12 as the upper one Embossing tool 3 and the contour stamp 11 in the lower Embossing tool end piece 7, however, has the same contour 13 as the lower embossing tool 4.
  • the lower stamping tool 4 is on a fixed press table 14 attached.
  • the cylinders 8 and 9 are equipped with a (not shown) Hydraulic or pneumatic unit connected.
  • a sheet 15 to be deformed is placed between the upper one Stamping tool 3 and the lower stamping tool 4 inserted.
  • the cylinders 8 in the upper embossing tool end pieces 6 are in a depressurized state.
  • the Cylinder 9 of the lower embossing tool end pieces 7 are located yourself in the printing state.
  • the contour stamps 10 and 11 are also located in its upper end position. Is the adhesion between the upper and lower embossing tools and the Contour stamp 10, 11 made, the downward movement the press 1 stopped.
