Definitions

  • the invention relates to a method and a tool assembly for explosive forming with the features of the preamble of claims 1 and 8.

  • a hollow-shaped metal blank is inserted into a recess of a die, wherein the recess corresponds to the shape of the body stump, the shape of the metal blank should take after forming.
  • a cylindrical extension of a gas pressure chamber is introduced into the metal blank which is open at the top.
  • a sealing membrane is located at the end of the cylindrical extension.
  • the device is secured with a slidable flat ring prior to igniting the gas mixture. After ignition of the gas mixture within the gas pressure chamber, the resulting shock wave breaks through the sealing membrane and then passes into the liquid-filled hollow body to deform it.

  • a multi-electrode device for the production and ignition of oxyhydrogen gas is in an elastic container, for.
  • oxyhydrogen gas is generated under water, which accumulates in the surrounding bag.
  • By igniting the detonating gas produced in the bag by means of a spark plug or a filament a pressure wave is generated in the water, which presses the workpiece into the mold.
  • this method is complicated and time-consuming.
  • the invention has for its object to improve a method and a tool assembly for explosive forming of the type mentioned in that the method and the tool assembly is simplified and suitable for mass production.
  • the provision of the gas mixture at least partially above the liquid surface ensures easy and rapid supply of the gas mixture.
  • the gas mixture is arranged here above the liquid surface, that is, is relatively widely spaced from the workpiece to be deformed, a good deformation result can nevertheless be achieved with the method according to the invention.
  • the explosion of the gas mixture and thus the formation of a detonation front takes place here above the liquid surface.
  • the power or energy transfer over the phase boundary Gas-liquid away is enough good to achieve a good forming result.
  • the required amount of gas can be reduced.
  • burns of the workpiece are largely avoided. Due to the high cycle times in today's production processes, the mold reaches high temperatures relatively quickly.
  • the liquid located in the receiving space can thus serve not only as a pressure transmission medium but also for cooling.
  • the gas mixture increases directly to the liquid surface.
  • the detonation front hits the surface of the liquid unhindered in this case, the direct application of the gas to the surface of the liquid achieves good force transmission across the gas-liquid interface.

  • the gas mixture can be at least partially passed through the liquid.
  • higher pressures can be achieved with otherwise constant gas quantity. It has been found that the gas is in a state in which an ignition of the gas leads to a significantly higher explosion pressure as a result of passing through the liquid such as water. This also results in a higher forming pressure acting on the workpiece.

  • the liquid bath can also serve as a buffer for further workpieces.
  • the ratio of explosive gas to liquid may be about 1:10 to 1:20, preferably 1: 2 to 1:15, and more preferably 1: 3 to 1:10. This ratio ensures a sufficiently large explosion force for forming and a good propagation of the detonation front also over the phase boundary.

  • the liquid level in the receiving space can be adapted to the production requirements. Also maximum fluid levels such. As a complete covering of the workpiece with liquid are possible.
  • the arrangement of the explosive gas mixture at least partially above the liquid surface allows easy and rapid filling. At the same time a good transfer of the explosive force or the detonation front across the phase boundary is possible. Although the gas mixture is arranged here above the water surface, a good forming result is achieved.
  • the receiving space can be filled via a valve with liquid. This allows a good control of the filling process and a good dosage of the amount of liquid.
  • a gas connection may be provided below the liquid surface.
  • the gas mixture can be passed through the liquid into the receiving space. This allows, depending on the gas mixture, higher forming pressures for the same amount of gas.

  • the detonation front can also spread inside the workpiece.
  • the workpiece may be filled with liquid in a workpiece holding region on which the workpiece is held in the mold.
  • the ends of the workpiece held in the mold are also protected from burns.
  • the design requirements for the tightness of lying in the tool holding area interfaces such. As the interface workpiece-forming tool, reduce. Liquid-tight interfaces are structurally easier to implement than z. B. gas-tight interfaces.
  • the entire workpiece cavity may be completely filled with liquid.
  • a large part of the workpiece surface is under the liquid and thus protected against burns.
  • a remaining, liquid-free workpiece cavity may be at least partially filled with the explosive gas mixture. This ensures easy filling with the gas mixture.
  • a remaining, liquid-free cavity which is spaced from the inserted workpiece, be at least partially filled with the explosive gas mixture.
  • This cavity ensures the absorption of a sufficiently large amount of gas and thus a good explosion and propagation of the detonation front regardless of the liquid level of the receiving space.
  • an ignition device may be arranged outside the workpiece cavity.
