Definitions

  • the invention relates to a method for explosive calibration of a mold according to the Features in the preamble of claim 1.
  • the prior art includes chilled block molds, in which in the tube walls Cooling channels introduced parallel to the longitudinal axis are provided, which with a Coolant can be applied.
  • tube molds and block molds are known, which in the Mold walls have vertical and / or horizontal channels into which Temperature measuring elements can be used.
  • each mold is first chrome-plated and then ground out. Subsequently a calibration mandrel is inserted into the mold The outer dimensions correspond to the inner dimensions of a new mold. To When the calibration mandrel is inserted, the end faces of the mold become tight with plates locked.
  • the outer surface of the mold is covered with a suitable explosive and this in an explosion-filled container filled with a liquid medium brought. Due to the explosion energy released on the one hand and the back pressure of the liquid medium, on the other hand, becomes the inner wall of the mold pressed against the calibration mandrel. In this way, the mold receives the the exact inner contour required for their use in the casting operation.
  • filler pieces preferably made of stainless steel, are introduced that are precisely adapted to the holes. Both the manufacture these filler pieces as well as their assembly in the holes and their disassembly associated with a comparatively high expenditure of time and production.
  • the invention is based on the object Process for explosive calibration of molds, in particular in the form of tube or Block molds, to create the easier to control and with a lower Effort is connected.
  • the invention is based on two measures that complement each other.
  • a Measure is the reinforcement of the end areas of the mold before Blasting calibration. This is done in particular by a build-up welding, so that the wall thickness losses are compensated for by casting.
  • To the Bores in the mold wall during explosive calibration are not inadmissible to deform, they are now calibrated with a flowable before explosive calibration Material filled in and sealed at the ends.
  • By using a flowable material can also on a comparatively simple basis different cross sections of the holes are taken into account. targeted Filler pieces placed on the cross sections of the holes are no longer required. The costly and time-consuming effort required for this is eliminated perfect.
  • the holes can be made according to claim 2 with an incompressible material, such as. Water to be filled.
  • the bores according to claim 3 with be filled in a bulk material.
  • the compressibility of the bulk material in connection with its pore volume is the compressibility of the bulk material in connection with its pore volume. The higher the compression of the Bulk material and the finer the grain size, the lower the pore volume of the Bulk goods and the higher the strength.
  • Another embodiment of the method according to the invention consists in that according to claim 4, the holes with a mixture of incompressible material and a bulk material.
  • the holes on the the entire length of the tube wall is made into the ends of its ends, this facilitates the production of the bores and thus also the production or Recalibration of a mold.
  • the holes are preferred according to claim 6 with a round Cross section made.
  • the tubular mold 1 illustrated in FIGS. 1 and 2 has a double T-shape configured cross section.
  • Holes 5 run in the tube wall 2 in the longitudinal direction LR of the tube mold 1 Bores 5 extend parallel to each other at a distance and emerge from the End faces 6, 7 of the tube wall 2. They have a circular cross section.
