Definitions

  • the invention relates to a device for explosive forming, with the features of the preamble of claim 1, (see, for example EP-A-0 830 907 ).
  • An ignition tube connects an explosion chamber in the workpiece interior with a gas supply, venting and ignition device, wherein the ignition device is integrated into the ignition tube.
  • the ignition device By means of the ignition device arranged in the ignition tube, the gas, oxyhydrogen gas in a stoichiometric mixture with low oxygen excess, is ignited. The explosion of the gas develops into a detonation wave, which transforms the workpiece and then expires.
  • the invention is therefore based on the object to improve a device of the type mentioned in that the detonation wave can develop well, the explosion process can run more orderly and that the ignition mechanism has a longer life.
  • the provided on the propagation path of the detonation wave shock breaker reduces the energy of the detonation wave whereby the device can be protected against high mechanical loads and thus also against permanent damage.
  • the strong mitigation of the reflected shock wave already causes an extension of the life of the ignition mechanism.
  • the impact crusher can be arranged between the ignition location and the ignition space exit.
  • the detonation wave which returns through the Zündraumausgang can be mitigated in their energy.
  • the shock breaker For example, the explosion propagating from the ignition location can develop sufficiently to reshape the workpiece as it passes through the mold.
  • the impact crusher can be arranged closer to the ignition location than the ignition chamber outlet. This has the advantage that the developing detonation wave, after passing through the impact crusher, remains an adequate distance through the ignition space in order to unfold, but the reflected detonation wave is reduced in its energy on reaching the impact crusher.
  • the impact crusher can be arranged directly at the ignition location.
  • the ignition device is still effectively protected against the reflected detonation wave. Nevertheless, the explosion can still be triggered there and develop from there.
  • the impact crusher can be arranged on the side facing away from the ignition of the mold.
  • the detonation wave is attenuated after passing through the mold by the impact crusher in its energy.
  • the explosion energy may be well-developed in the detonation wave until the detonation wave reaches the mold.
  • the impact crusher can be arranged directly on the mold on the side facing away from the ignition.
  • the detonation wave passing through the mold can thus be dampened in its energy immediately after passing through the mold.
  • the impact crusher may be located closer to the end of the device opposite the ignition location. The reaction from the detonation wave striking the impact crusher to the mold could thus be reduced.
  • the impact crusher forms the end of the device opposite the ignition location.
  • the impact crusher could act as a scattering element, which strikes the detonation wave.
  • the impact crusher can be arranged within a support tube which can be attached to the mold on the side remote from the ignition location of the molding tool.
  • the support tube could be made of a different material than the impact crusher and simplify the construction of the impact crusher as an insert.
  • the impact crusher in unit with the support tube may be designed as an end piece. This tail could connect directly to the mold and complete the device on the opposite side of the ignition space. A longer discharge path for the detonation wave could be omitted in this way.

  • the flow resistance through the impact crusher in the flow direction from the ignition location can be greater than towards the ignition location, and the impact crusher can be mounted on the side of the molding tool facing away from the ignition location.
  • the shock wave energy can be withdrawn to a considerable extent even before it is reflected at the end of the device.
  • the impact crusher can have at least one Drossef Wegschlag element. This allows the propagating explosion to pass through the shock absorber while the reflected detonation wave is decelerated by the recoil element prior to the ignition mechanism.

  • the impact crusher can have a larger surface area than the ignition space inner surface or supporting surface which is adjacent to the impact crusher. This can lead to increased friction with respect to the length of the impact crusher and thus to an improved reduction in the energy of the reflected detonation wave.
  • the ignition space cross section and / or the support tube cross section in the region of the impact crusher can be increased. This creates an increased space especially for complex impact crushers.
  • the impact crusher may have at least one branch off-going from a main passage.
  • the detonation wave can be split, whereby likewise the energy of the detonation wave is divided and can be reflected and absorbed several times in the area of the branching.
  • the at least one branch may be at least partially branched. This creates a multiplicity of branch points at which the detonation wave can be split up.
