  • a blasting apparatus 1 of the first embodiment of the present invention is configured so that an expansion force produced when a thin metal wire (for example, copper is used) 8 is fused and vaporized rapidly by the supply of electrical energy is transmitted by means of a blasting substance (water or oil is used) 3, so that a to-be-blasted object H1 is blasted by using the expansion force.
  • This blasting apparatus 1 is particularly suitable for blasting a plate-shaped to-be-blasted object H1.
  • the blasting apparatus 1 has a blasting vessel 2 which abuts on the surface of to-be-blasted object H1.
  • This blasting vessel 2 is configured so that one end (on the side of the to-be-blasted object H1) is open and the other end is closed, and it is provided with an expansion force generating section A for causing the thin metal wire 8 to generate the expansion force.

  • the energy supply circuit 9 is connected between the terminals 5, 5 of the pair of electrodes 4, 4, and the charging switch on the controller 11 is turned on to thereby charge electrical energy in the capacitor 13. Then, the electrical energy is supplied to the thin metal wire 8 via the electrodes 4, 4 for a very short period of time by turning on the discharge switch 12. Alternatively, electrical energy has been charged in the capacitor 13 in advance, and the electrical energy is supplied to the thin metal wire 8 via the electrodes 4, 4 for a very short period of time by turning on the discharge switch 12.

Since the filling port 18 and the discharge port 19 are closed sealingly by the valve devices 20 and 21, and the blasting vessel 2 is pressed toward the to-be-blasted object H1 by the rod 25 of the air cylinder device, the generated expansion force acts on the pressure receiving surface 33 of the shock delivering member 22, so that the sharp noses 23 of the shock delivering member 22 deliver a shock to the surface of the to-be-blasted object H1, whereby the to-be-blasted object H1 is blasted or embrittled.

  • the sharp noses 23 of the shock delivering member 22 are caused to abut on the surface of the to-be-blasted object H1 and the rod 25 of the air cylinder device is caused to abut on the other side of the blasting vessel 2, the blasting vessel 2 is pressed toward the surface of the to-be-blasted object H1 against the pressure of the blasting substance 3 by driving the air cylinder device, and the energy supply circuit 9 is connected between the terminals 5, 5 of the electrodes 4, 4. Thereafter, the charging switch on the controller 11 is turned on to thereby charge electrical energy in the capacitor 13. Then, the electrical energy is supplied to the thin metal wire 8 for a very short period of time by turning on the discharge switch 12.
  • the thin metal wire 8 is fused and vaporized rapidly, and the blasting substance 3 is vaporized rapidly, so that an expansion force is generated at this time.
  • the sharp noses 23 of the shock delivering member 22 deliver a shock to the surface of the to-be-blasted object H1, whereby the to-be-blasted object H1 is blasted or embrittled.
  • the blasting vessel 2 and the shock delivering member 22 can be used repeatedly because they are formed of a metal so as to be able to withstand a shock caused by the expansion force of the thin metal wire 8 and the blasting substance 3.
  • the shock delivering member 22 is caused to collide with (pressed strongly on) the surface of the to-be-blasted object H1 by using the expansion force of the thin metal wire 8 and the blasting substance 3. Therefore, even if the to-be-blasted object H1 has a plate shape, it can be blasted by effectively using the expansion force of the thin metal wire 8 and the blasting substance 3.
  • the blasting vessel 2 and the shock delivering member 22 are formed of a metal so as to be able to withstand a shock caused by the expansion force of the thin metal wire 8 and the blasting substance 3, so that they can be used repeatedly.
  • the blasting probe P is made up of the pair of electrodes 4, 4 inserted through a cover member 2b and the thin metal wire 8 connected between the electrodes 4, 4. Therefore, when the blasting work is performed continuously, the blasting apparatus 1 can be formed by merely replacing the blasting probe P, which is convenient and increases the working efficiency.

  • the filling and discharge of the blasting substance 3 are performed through the filling port 18 and the discharge port 19 formed in the drum of the blasting vessel 2, respectively.
  • the generated expansion force acts concentrating on the central portion of the pressure receiving surface 33 of the shock delivering member 22 by the function of the reflecting face 35 formed into a conical shape. Therefore, the to-be-blasted object H1 can be blasted reliably by the shock delivering member 22.
  • the reflecting face 35 is formed into a conical shape in the aforementioned second embodiment, the shape is not limited to this, but the reflecting face may be formed into a hemispherical or parabolic face or other curved faces.
  • the expansion force generated when electrical energy is supplied to the thin metal wire 8 acts concentratedly on the central portion of the pressure receiving surface 33 of the shock delivering member 22 by the function of the reflecting face 35. Therefore, the to-be-blasted object H1 can be blasted reliably by the shock delivering member 22.

  • the blasting apparatus 1 configured as described above, a plurality of pairs of electrodes 4, 4 are inserted through the cover member 41, and the thin metal wire 8 is connected between each pair of electrodes 4, 4, by which the blasting probe P is formed. Therefore, the expansion force generated when electrical energy is supplied to each thin metal wire 8 is higher than the case where one thin metal wire 8 is provided, and the expansion force acting on the pressure receiving surface 33 of the shock delivering member 22 increases. Thereupon, since the force by which the sharp nose 23 of the shock delivering member 22 presses the surface of the to-be-blasted object H1 increases, the blasting force can be increased, and the to-be-blasted object H1 can be blasted reliably. Each time the blasting work is finished, the blasting probe P is replaced, and the blasting substance 3 in the blasting vessel 2 is replaced.
  • the rod 25 of the air cylinder device which presses the other side of the blasting vessel 2 is formed into a hollow shape, and the tip end portion of the rod 25 is also used as the cover member 41 which covers the opening 40 formed on the other side of the blasting vessel 2.
