Definitions
- the invention relates to an apparatus for explosive forming, with the features of the preamble of claim 1.
- 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 gas arranged in the ignition tube ignites the gas, oxyhydrogen in a stoichiometric mixture with a slight excess of oxygen.
- 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 Zündmechänismus 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 impact crusher has and / or generates a curved and / or reduced passage with respect to the ignition space cross section or the support tube cross section. These transmission modes can consume a significant amount of energy for the reflected detonation wave.

- the impact crusher can have at least one throttle check element. This allows the propagating explosion to pass through the impact crusher while the reflected detonation wave is decelerated by the recoil element in front of the ignition mechanism.
- the impact crusher may comprise at least one disposable element. This allows the explosion to pass through the impact crusher while intercepting the reflected detonation wave from the disposable element prior to reaching the ignition mechanism.
- the impact crusher can have a larger surface area than the ignition space inner surface or support tube inner surface 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 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.
- the at least one branch can be closed at its end, whereby the detonation wave can remain inside the impact crusher.
- At least one of the branches can form a filling channel for fluid.
- the liquid used in a variant of the explosion design could be introduced into the device via the impact crusher.

- the impact crusher can have at least one labyrinth element and / or a plurality of impact crusher elements forming a labyrinth structure. Depending on the situation, it may be better to form the labyrinth from one or more labyrinth elements or from several elements that together form a labyrinth structure.
- the first is recommended z. For example, in a small space, while the second option can be simpler and cheaper to manufacture.
- the passage may be formed approximately meander-shaped.
- the meander shape with its diverse and strong deflections can reduce the energy of the reflected detonation front very effectively.
- the impact crusher may comprise at least one disc-like impact crusher element with at least one passage through the disc.
- the disc can provide a large baffle in the form of its face with low manufacturing cost.
- the impact crusher element is designed as a cylindrical disk. As a result, it can be stably formed while providing a long passage for reducing the energy of the reflected detonation front.

Only one branch 26 is shown, although a plurality of such branches may be formed at a plurality of angles to the main passage 30. At its end, the branch 26 is closed.

- the figure can also be understood to mean that it is a cross-section and as indicated by the dashed lines within the impact crusher 9, the recesses have a pyramidal shape.
- the incident from the flow direction 36 detonation wave can be broken several times, so that the energy of the impinging detonation wave is divided on a variety of reflected back at different angles shock waves.
- the maximum energy which can occur after reflection at the impact crusher 9 in a reflected back shock wave can thus be reduced with respect to the detonation wave.
