Definitions

  • a method and apparatus of explosive-plating or -hardening of metals in a safety explosive chamber dampened to noise transmission comprising equipping a workpiece to be explosively treated with an explosive charge, coating the workpiece and the explosive charge together completely with an air-tight envelope, inserting the coated workpiece and explosive charge into a safety explosive chamber spaced from the walls thereof, subsequently subjecting the chamber with the coated workpiece and the explosive charge to vacuum, and igniting the explosive charge.
  • the present invention relates to a method of and apparatus for explosive treatment of metals in general, and to a method of explosive treatment of metals in a noisedampened safety explosive chamber, as well as an explosive chamber for performing the method, in particular, whereby the explosive chamber comprises a substantially ball-shaped container, which is equipped with a transportation door capable of being closed, as well as with a gas escape tube equipped with a noise silencer.
  • the workpiece to be treated and the explosive is equipped together with an air-tight envelope prior to the insertion thereof into the explosive chamber.
  • the material for the envelope should furthermore suitably be such, that no splinter effect occurs during the performance of the explosive treatment in the explosive chamber.
  • FIGURE 1 is a vertical section of the apparatus for explosive treatment of metals
  • FIG. 2 is a vertical section of another embodiment of the apparatus for performing the method of the present invention.
  • FIG. 3 is a workpiece shown, by example, with an envelope surrounding the workpiece indicated in section.
  • the apparatus designed in accordance with the present invention comprises an explosive chamber which consists of a substantially ball-shaped container 1, which is made of steel suitably nonsensitive against brittleness, or of a corresponding material, as for instance pretensioned steel concrete.
  • the container 1 rests on a portable frame 2 and is anchored with the latter in a strongly reinforced concrete base 3.
  • a loose granular material which is disposed inside of the container 1 in form of a heap 4 of a predetermined height, maximum explosive loads can be brought to detonation.
  • the container 1 is furthermore equipped with a flanged escape tube 5 through which the partly poisonous gases created during the detonation and consisting of C0, C0 and N0 can escape.
  • the sound waves created during the detonation are still further dampened by means of a silencer 6 disposed in the escape tube 5.
  • the workpiece to be treated is at first inserted with the explosive applied thereto through the transportion door 7 into the container 1, and is supported by the sand accumulations 4.
  • the container 1 is pumped to a heavy vacuum in advantageous manner by means of a vacuum pump 10, for instance, a rotary pump, a piston pump, or a steam jet pump while the explosion flap 8 is closed, which is disposed at the entrance of the pump pipe 9 into the gas escape tube 5.
  • a vacuum pump 10 for instance, a rotary pump, a piston pump, or a steam jet pump
  • the explosion flap 8 is closed, which is disposed at the entrance of the pump pipe 9 into the gas escape tube 5.
  • a valve 11 is closed and the explosive is brought to detonation.
  • the explosion flap 8 Upon opening the explosion flap 8 the detonation gases expand and escape partly through the escape tube 5 and the noise silencer 6.
  • the opening explosion flap 8 closes thereby the pump tube pipe 9.
  • the explosion flap 8 falls back into its original position and the valve 3 11 and the fresh air valve 12 are opened in the escape pipe 5.
  • the remaining poisonous detonation gases are then sucked off through the air filter 13 by means of the vacuum pump 10.
  • the transportation door 7 is opened again and the explosive treated workpiece is removed from the container 1. Then, the next working cycle starts.
  • the container 1 is, as can be determined from FIG. 2, advantageously disposed on columnar portable frame 14, which is equipped with hydraulic or mechanical resilient and damping operating elements 15.
  • the expansion and transmission of the shock waves during the detonation of the explosive in the container 1, as well as its effects are, furthermore, very strongly reduced in an advantageous manner such that the concrete foundation 3 mounted in a material 16, preferably sand absorb ing the created ground waves and has a weight up to 100 times the weight of the container 1.
  • the concrete foundation is further mounted advantageously on a further concrete plate 17, whereby hydraulic or mechanical spring elements 18 are provided between the concrete foundation 3 and the concrete plate 17.
  • the slot grooves provided in the range adjacent the concrete foundation 3, which slot grooves 19 are additionally filled advantageously with material absorbing the ground waves, serve the same purpose.
  • the feed lines and escape lines are connected elastically with the container 1.
  • the container 1 with the concrete foundation 3 is surrounded by a wall 20, consisting of bricks, concrete or tiles, which wall is covered at its inside with a layer 21 of sound-damping material and at its outside an embanking 22 of dirt is provided whereby the space defined by the wall is equipped with a transportable roofing 23.
  • a bracket sheet 25 is applied by means of explosive on a base work material sheet 24, the required explosive 26, as well as suitably used intermediate layer 27, is arranged in an air-tight envelope 28, as clearly shown in FIG. 3, which FIG. 3 shows an elevation in the direction of detonation.
  • the envelope 28 is advantageously fortified by additional webs 29.
  • the workpiece to be explosively treated for explosiveplating or -hardening is equipped with an explosive charge.
  • the workpiece and the explosive charge together are then completely coated with an air-tight envelope and in this manner inserted into the explosive chamber spaced from the walls of the chamber.
  • the chamber is then evacuated and the charge then detonated.
  • the shock wave pressure to the container wall created during the detonation of the explosive in the container 1 is appreciably reduced, whereby the durability of the container is tremendously increased.
  • the sound level caused by the acoustic shock of the detonation is simultaneously appreciably reduced.
  • vacuum produced in the explosive chamber has no influence on the explosive and its detonation, re-
