Definitions
- the invention relates to a method for producing expanded metal elements
- An expanded metal mesh is a material with openings in the surface. They result from staggered cuts without loss of material and stretching at the same time. The stitches of the material made from panels or ribbons are neither braided nor welded.
- the type of stretched mesh is defined by the following key features: mesh length, mesh width, mesh size, web width, web thickness, node, knot length, knot width and web grid thickness.
- State of the art is the production of an expanded metal mesh element according to fixed dimensions. That is, per element remain the above-mentioned features always constant, no matter the diamond shape or the constant web width pattern of the mesh, apart from usual tolerances in metalworking.
- web width pattern within a grid element can be the same permanent web thickness (determined by the sheet thickness) the dimensional stability or Breakthrough time to be adapted to the purpose.
- the invention has for its object to provide a way that eliminates the disadvantages of the prior art.
- the object is achieved in a method for producing expanded metal elements in that the advance of the material from which the expanded metal mesh is produced is varied in accordance with the static properties of the finished expanded metal mesh.
- the advantage of the invention consists in the much better visual appearance, the saving of fasteners and distortion factors, the increase in performance characteristics variable according to the requirements of the user, a lower consumption of the starting material and a significant saving of assembly time and the saving of material costs.
- Fig. 1 the sequence of producing a stretched grid 1 of a Metal sheet 2 shown.
- the metal sheet to be processed is 2, with a projection which is equal to the web width 5 to be achieved, see FIG. 2, inserted and the schematically illustrated punch 3, the cutting and the Stretching moves, indicated by the arrow marked down.
- the punch 3 is moved upward.
- the third sequence is already to recognize the first stretching pattern of the expanded mesh 1 to be created.
- the Stamp 3 is defined horizontally, here to the right, by a half stitch length 4 (defined as shown in FIG. 3).
- the metal sheet 2 is again around the web width. 5 advanced.
- the stamp 3 is again down guided and then, as seen from the fifth sequence, back up.
- the first stitches were made.
- the Stamp 3 again horizontally, but this time in the opposite direction to the half stitch length led to its starting position.
- the metal sheet 2 becomes advanced simultaneously around the web width 5.
- the Shape of the punch 3 specifies the mesh width 6 according to FIG. 3.
- By change the stamp form are stitches, as shown in Fig. 4, can be produced.
- Fig. 5 a section of a stretched grid 1 is shown, which after production was still rolled flat.
- Fig. 6 clearly shows the two still connected Parts, namely the metal sheet 2 and the expanded metal grid 1.
- the web thickness 7, as shown in FIG. 2, is defined by the thickness of the metal sheet 2.
- a change in the stability of the Expanded mesh 1 is thus given by two options, either one varies Thickness of the metal sheet used 2 or you change the feed of the metal sheet 2 and thus varies the web width 5.
- Fig. 7 is an inventive expanded metal mesh 1 shown. The lower three courses show a wider web width 5 as the top three courses. This was achieved by using the first three production cycles described above with a constant feed worked, which was then shortened and thus the next three Mesh rows were then produced with the then constant feed.
