Definitions

  • Outdoor air grilles of this type are known and are available in a wide variety of designs and types from the market. Such outside air grilles differ primarily in the size, arrangement and number of the assigned slats in a corresponding frame. For example, there are outside air grilles with a few wide fins or those with a rather narrow and therefore many fins.
  • the process is energy-wasting due to the energy required for the various punchings as well as for the welding apparatus and due to the energy consumption necessary for operating the suction devices prescribed for such work.
  • the inventor has set himself the task of creating a method for producing an outside air grille which can be carried out in a more cost-effective, environmentally friendly and energy-saving manner.
  • a sheet in particular a steel sheet, is cut to the size of the later external air grille, then kink lines are embossed into the sheet as one side of the lamellae, and then slots which circumscribe the other sides of the lamellae are cut out be punched and punched and that in a further working step each lamella is angled at an angle around the fold line.
  • a steel sheet, a sheet metal or the like or a plate of a desired material is required for the production, which corresponds in contours to the shape of the later outlet grille, with as much material being taken into account on the edge as is necessary for the later folding of an edge strip is.
  • This sheet is then embossed by means of a special and special manufacturing process, at the connection points of lamella and sheet, the remaining contour is cut out or punched and, if necessary, licked out.
  • the contours of the slots circumscribe the sides of the slats that will later be bent. Slats of this type preferably have an approximately rectangular, strip-like shape. The size of the possible coverings depends on the width of the edge strips provided.
  • a method of this type for producing outside air grilles is very quick and inexpensive. By using a single sheet there is hardly any waste so that an enormous saving in raw materials is guaranteed. Since there are no individual parts that have to be welded, glued or screwed, on the one hand a considerable part of the energy costs are eliminated, and on the other hand there is no need for expensive machines that would be necessary for the production of the individual parts.
  • the saving in the number of work steps also reduces the risk of injury and thus injury-related lost work, which also has an impact on other process technologies.
  • an outside air grille R has a flat sheet 1, from the plane of which rectangular slats 3 are preferably bent out. These fins 3 are produced by an embossing and subsequent stamping process and a subsequent bending.
  • bend lines 4 are embossed into the sheet metal, which define the connection of the lamellae 3 to the sheet metal 1.
  • the three free sides of the slats 3 are then produced by a punching process, a U-shaped slot 2 being cut into the sheet metal 1 by this punching process. This U-shaped slot 2 is closed by the crease line 4.
  • the slats 3 slotted on three sides are pressed with a special tool in a corresponding manufacturing process in the direction x and bent at a predetermined angle w to the plane of the sheet 1.
  • the angle w at which the lamellae 3 protrude from the plane of the steel sheet 1 can be determined in each case before machining.
  • the folding tool can be adjusted accordingly.
  • edge strips 7 are also preferably bent at an angle v that can also be predetermined.
  • fold lines 5 are stamped into the edge 1 of the sheet metal, each of which marks an edge strip 7.
  • Special tools can then also be folded the edge strips 7 at the same time.
  • the outside air grille R thus produced is placed in a further work step, a connecting piece 8 to an air guide system, not shown in detail.
  • the outside air grille R is fastened via fastening elements, not shown, such as screws, rivets, clips or the like.
  • the connecting piece 8 itself is housing-shaped, the outside air grille R abutting a circumferential flange 9. Side walls 10 run from this flange 9 to a rear wall 11 which, as is only indicated schematically, has corresponding passages 12.
  • the design of these passages 12 is at the discretion of the user, and these passages can be slot-shaped, perforated plate-like or can also be covered with lamellae.
