Definitions

  • the invention relates to a metal mesh according to the preamble of claim 1 and a tool for Production of expanded metal, according to the preamble of claim 8.
  • Expanded mesh with meshes is known, which in the delivery state e.g. are diamond-shaped or square-shaped. Based on these Geometry is inevitably longitudinal expansion and transverse contraction coupled. A relative results from this known property low formability of expanded metal on spatially strong curved surfaces. This restriction is due to denominations or folding or cutting and material duplication rather overcome with difficulty.
  • a plastically modelable, metallic expanded metal as Reinforcement insert for an arch, web or strip Covering material with high adaptability to complex three-dimensional Shapes, usable e.g. as a weather strip for one Ridge or ridge cover is known from DE 36 42 063.
  • This Cover material consists essentially of an elastomer layer and the expanded metal grid serving as a reinforcing element.
  • the expanded metal grid has an extensibility in the longitudinal direction from 50 to 150% or an extensibility in the transverse direction ⁇ 20% that are mutually exclusive and a provision ⁇ 5%.
  • a very easily sculptable, metallic expanded metal is also known from EP 0 797 486 (closest prior art).
  • Expanded metal grids are staggered from row of stitches to row of stitches two grid nodes each through an incision perpendicular severed to the actual stretch cut.
  • Such one Expanded metal grille is characterized by excellent formability out.
  • a disadvantage of the known expanded metal is that it cannot be produced in an economical manner. Also lets the handling compared to normal expanded metal left something to be desired.
  • the invention has for its object to an expanded metal create that produce in an economical manner and can be stretched in two directions at the same time, or at least exhibits no transverse contraction when stretched longitudinally. task the invention is also the creation of a tool for economical production of expanded metal.
  • the expanded metal mesh according to the invention is characterized in that that it is cut, for example, that certain webs only very thinly connected with each other, some of the Lattice nodes are thus designed as predetermined breaking points.
  • the manufacturing process is therefore the same as for normal expanded metal and the expanded metal thus produced can also be used in the same way Manage and process comfortably like normal Expanded metal mesh.
  • the expanded metal mesh according to the invention a uniformly smooth surface and it does not exist the risk of mutual interlocking, such as in an expanded mesh according to EP 0 797 486, at the mesh node through a separating cut perpendicular to the actual stretch cut are severed.
  • the lattice nodes in the lattice according to the invention predetermined breaking points in a regular sequence. For example, you can move from course to course every second or two of three grid nodes be designed as a predetermined breaking point.
  • Another variation is to grid at least locally to form limited lattice sections with predetermined breaking points, with marginal areas to avoid unwanted tearing can be designed without predetermined breaking points.
  • To increase the stability and strength can such lattices in Angle and especially superimposed at right angles and be connected to each other at the crossing points.
  • the grid according to the invention with the formation of individual grid nodes as a predetermined breaking point is also with an expanded metal improved stretching behavior in the starting from trapezoidal sheet, corrugated sheet or the like Sheet metal the stretch cuts are made so that certain Bridges are only connected to each other very thinly these points are predetermined breaking points.
  • the weakened predetermined breaking grid nodes can be used with a conventional one Tool during production enlarged cut-depth setting can be generated. With a Such a conventional tool can only be used for predetermined breaking grid nodes consistently across the entire grid.
  • predetermined breaking points are only in a regular sequence, for example only at every second or third grid node can be generated with a tool with different deeply worked tooth bases.
  • a tool with different deeply worked tooth bases.
  • predetermined breaking grid nodes the depth can be reduced a smooth cutting of individual lattice nodes on the tooth bases take place so that a lattice according to EP 0 797 486 is obtained, i.e. a grid, which is offset from course to course for example every second and / or third grid node is severed, which is a perfectly spherical lattice results.
  • Expanded mesh is usually produced as in FIG. 1 shown.
  • the sheet 20 to be stretched is intermittently over a Cutting edge 21, which forms a lower knife, advanced.
  • an upper knife 22 lowers itself with a toothed face 23 slits the sheet 20 long since the cutting edge 21 and presses the protruding sheet metal strip while stretching obliquely down.
  • a half stitch is formed. in the next stroke the upper knife lowers e.g. 1 ⁇ 2 mesh width laterally offset, which completes the expanded mesh becomes.
  • Expanded mesh tools are used with expanded mesh tools of a known type manufactured that are invariably solid or very slightly different tight knots and straight stretched in between, slightly corrugated at best for decorative purposes have "festooned mesh” bridges.
  • all of these expanded metal according to the prior art even those with regular asymmetrical Mesh shapes is de facto straight Do not systematically bridge the distance between the respective nodes and specifically changeable.
  • this variable knot spacing is of crucial importance and for the first time through tools modified according to the invention economically interesting.
  • Teeth is molded.
  • a shear knife 1 with teeth 2 is shown schematically in Figure 2. While the tooth tips 3 are the same throughout, only every second tooth base 4a is like this wide as the tooth tips 3. The rest of the teeth 4b are less deep and narrower.
  • This is in accordance with 3 and 4 a expanded metal 5 can be produced with alternating normally connected webs 6a and almost severed webs 6b (Break points).
  • FIG. 5 is a similar expanded metal 7 in partially stretched State shown.
  • the circles 8 designate them almost severed webs 6b, and points 9a and 9b one earlier contiguous knot. By enlarging the mesh there is an elongation of about 35% without transverse contraction.
  • FIG. 6 is a similar expanded metal 10 with a different knife guide shown. Here the shear knife is cut twice moves to the right or to the left, as at the, the predetermined breaking points characteristic circles 11 can be seen.
  • FIG. 8 shows two superimposed at right angles Expanded mesh 13a and 13b that are continuous or intermittent are designed with predetermined breaking points 14.
  • the superimposed grids can by an embedding compound be firmly connected.
  • the invention was in connection with Expanded metal described. Basically, the invention is based on any perforated sheet can be used.
  • the Expanded mesh 13a and 13b in Fig. 8 also as perforated sheets with almost square holes and incorporated at the same time Predetermined breaking points 14 are produced.
  • Features 1 to 5 are preferably in a regular sequence realized across the tool width, e.g. on every second or third tooth, on two out of three teeth or in others appropriate combinations.
  • By changing the respective Cutting depth then results in weakened knots (Breaking points) or already severed "loose” knots, whereby by conventional knife offset by 1/2 grid mesh width between two strokes with knives acc. Fig. 9 and 15 expansion grids with partly straight, partly angled bars 11 to 14 and 16 to 19, while knife acc. Fig. 15 with an enlarged to 3/2, 5/2, ... (2n + 1) / 2 stitch widths Offset expansion grid with consistently angled webs 20 to 22 result.
