Definitions

  • the invention relates to a carrier plate for a punching tool with two outer layers, between which a central layer is arranged.
  • a carrier plate for a punching tool with at least two layers is from the DE 203 20 658 U1 known.
  • the middle layer of this carrier plate is preferably made of a foamed plastic, in particular epoxy resin.
  • the outer layer consists of a composite material of synthetic resin and glass fabric or metal.
  • a disadvantage of in the DE 203 20 658 U1 The disclosed carrier plate is the use of non-recyclable epoxy resins in the middle layer of the carrier plate. Furthermore, the materials used are relatively expensive to produce.
  • composite plates are known as carrier plates in die making. These consist, for example, of a composite of sheet metal / wood / sheet metal, sheet metal / plastic / sheet metal or sheet metal / sisal, resin / sheet metal.
  • a carrier plate made of a composite of metal / plastic / metal is made of DE 24 044 06 C3 known.
  • an epoxy resin is preferably used in the middle layer, the outer layer is preferably made of a dimensionally stable metal, for example copper, brass, aluminum or magnesium.
  • Another disadvantage is the relatively high weight that results from the use of metals for the upper and lower outer layer. This will u.a. the handle of the support plate difficult to install in the punching apparatus.
  • carrier plates for die making consist of multiplex boards from Neufurnier. These consist of at least 5 equally strong veneer layers of mostly beech, birch, spruce or maple with thicknesses of 0.5 - 2.5 mm. The plates are pressed with urea glue and cross-bonded. There are also multiplex panels from one Mixture of different types of wood used. These carrier plates have a high dynamic life.
  • the invention has for its object to provide a support plate for a punch that can be produced with relatively low cost, however, has a high dynamic life, and in which can be formed with the help of a laser precisely fitting recesses.
  • the support plate is formed on both sides with an outer layer of wood veneer.
  • This can be formed from a wood veneer layer, but preferably from two cross-laminated wood veneer layers, preferably from birch veneer.
  • the layers are glued together with a glue and using pressure.
  • the outer layers are connected to the middle layer by means of a laserable glue, preferably urea glue.
  • the mid-ply consists of a medium density fiberboard (MDF), low density fiberboard (LDF) or high density fiberboard (HDF) of coniferous and / or hardwood fibers coated with synthetic binders and waxes wetted are made plate-shaped under a hot pressing process.
  • MDF medium density fiberboard
  • LDF low density fiberboard
  • HDF high density fiberboard
  • binders are used that are both environmentally friendly and biodegradable.
  • the MDF core used is an MDF core type "H". This has a small length and thickness swelling when using a waterproof glue.
  • the wood veneers have a thickness of 0.1 - 2.5 mm and the middle layer has a thickness of 2.4 - 21.8 mm, wherein the thickness of the central layer is 30 to 99% of the total thickness of the support plate.
  • each case between the two layers of wood veneer is a reinforcement made of plastic, metal or glass fiber fabric with a thickness of 0.05 - 0.5 mm, which has a lattice-like structure with a mesh size of 0.05 - 5 mm. It is expedient to apply a wood glue-compatible size in a thickness of not more than 0.001 mm (1 ⁇ m) to this reinforcement and then glue the two layers of wood veneer together transversely.
  • the support plate is finally ground flat by a grinding process and calibrated to a standard size with a thickness tolerance of ⁇ 0.3 mm.
  • the surface of the carrier plate is preferably coated with a water-soluble acrylic lacquer (UV-cured) or with a melamine film.
  • the carrier plate according to the invention can therefore be produced with relatively little effort and nevertheless fulfills all the required properties. These include u.a. a high dimensional stability even after a high number of punching operations, a low moisture absorption, a good wettability, a high rigidity and compressive strength and a good flatness with low thickness tolerance.
  • renewable raw materials can be used, resulting in a positive environmental balance through the use of secondary materials.
  • a proportion of secondary raw materials of 30-99% can be achieved.
  • support plate 1 has three layers, a central layer 2 consisting of a plate-shaped MDF fiber core and two outer layers 3, 4, which are each formed by two cross-glued layers 5, 6 and 7, 8 as error-free and uniform birch veneer.
  • the middle layer 2 and the outer layers 3, 4 have been glued by means of a urea glue under pressure and temperature, wherein the outer layers 3, 4 are cross-bonded to each other.
  • the support plate 11 of Fig. 2 differs from the carrier plate 1 of Fig. 1 characterized in that between the two layers 5, 6 and 7, 8 made of birch veneer a reinforcement (9, 10) made of glass fiber fabric with a mesh size of 1.7 mm and a thickness of 0.3 mm, which with a size of 1 micron Chromium or Silanschlichte was treated. Subsequently, the two layers 5, 6 and 7, 8 of birch veneer with the intermediate reinforcement are glued transversely to each other. The reinforcement serves in this embodiment to minimize the expansion forces.
  • the middle layer 2 consists in both described support plates 1 and 11 to 85-90% of wood of coniferous trees (spruce, fir, pine) and 10-15% of hardwood (beech, oak, maple).
  • the entire support plate 1 or 11 has a thickness of 18.2 mm, wherein the birch veneers each have a thickness of 1.4 mm and the middle layer 2 has a thickness of 12.6 mm (2 * 1.4 mm birch veneer above, 12.6 mm center layer, 2 * 1.4 mm birch veneer below).
  • the thickness tolerance of the middle layer 2 is ⁇ 0.2 mm and the curvature should not exceed 1.5 mm / m.
  • the MDF middle layer 2 used has an average density of 770 kg / m 3 , the density tolerance being ⁇ 30 kg / m 3 .
  • the transverse tensile strength is ⁇ 0.75 N / mm 2 and the flexural rigidity ⁇ 35 N / mm 2 .
  • the surface is coated with a water-soluble acrylic varnish (UV-cured) for protection.
  • UV-cured water-soluble acrylic varnish
  • the support plates 1 and 11 Due to the preferred use of birch veneer in the outer layers 3, 4 and the MDF core as the center layer 2 of the support plate 1, the support plates 1 and 11 have a good laser cutting ability.
  • the preferred use of a special urea glue (BFU-20) leads to a laser-capable gluing of the carrier plates 1 and 11.
  • BFU-20 a special urea glue
  • the cutting speed of the carrier plates 1 and 11 according to the invention corresponds to the standard values.
  • the dimensional accuracy of the cutting die can be maintained with nominal dimensions of 0-1000 mm with ⁇ 0.6 mm and with nominal dimensions> 1000 mm with ⁇ 0.7 mm.
  • the homogeneity in the entire plate structure, which is important for laser cutting, can be maintained by using the MDF core in the middle layer 2.
