For example, a bullet is driven into a liquid such as water for pressurization to generate impact hydraulic pressure in the liquid, the pressure is applied to a member such as a plate material, and the member is pressed into a mold to form a three-dimensional molding. Japanese Patent Application Laid-Open No. 01-157725 discloses an impact hydraulic pressure generator, a molding apparatus for generating an impact hydraulic pressure by burning explosive in water, and performing a three-dimensional molding of a thin plate by the pressure, and further, There is a device in which an impact hydraulic pressure is generated by causing a piston accelerated at high speed by gas pressure or the like to collide with the liquid surface of a pressurizing liquid contained in a container.

The shape or size of the hydraulic chamber must be determined in consideration of the behavior of the energy source (explosive, high-speed projectile), the degree of freedom is considerably small, the pressure duration is long, and In addition to common problems such as simultaneous application of impact pressure over a wide range, risk of installation, restrictions on installation location or consideration of safety, etc., there are also unique problems. .

The liquid surface of the hydraulic chamber faces the opening formed at the other end. As the flame in the combustion chamber progresses, the cross-sectional area of the combustion chamber becomes smaller, so the pressure rises, and the pressure at the other end becomes extremely high. This high pressure is converted into the hydraulic pressure of the liquid in the hydraulic chamber. If a processing chamber having a mold is provided in the hydraulic chamber and a member to be processed such as a plate material is arranged on the mold, it is possible to perform processing into a predetermined shape along the mold by the hydraulic pressure. Further, the liquid pressure chamber may be an elastic pressure chamber having a rubber-like elastic body instead of the liquid.

め）。In the above detonation hydraulic pressure generator, the hydraulic chamber has an increased cross-sectional area from the converging portion toward the pressure receiving portion in order to obtain a pressure receiving area corresponding to the size of the member to be processed. It has a conical shape. Further, the pressure wave propagating toward the pressure receiving portion in the hydraulic chamber is a spherical wave because it is perpendicular to the inner wall surface of the cone of the hydraulic chamber. Therefore, the pressure acts on the member to be processed in the pressure receiving portion so that the pressure spreads toward the periphery after the pressure reaches the central portion. Then, the maximum pressure is obtained in the central part of the member to be processed, and the pressure monotonously decreases toward the outer peripheral part (because the wave propagation distance becomes long).

In this case, if the explosion pressure is determined according to the part with the maximum degree of processing, unnecessary pressure will be applied to other parts unnecessarily, energy will be wasted, and cracks will occur at parts where excessive pressure is applied. Cheap.

Since it is not used, it is possible to obtain an effect that the device is not restricted by the setting, and further, it becomes possible to continuously generate the impact elastic pressure having various distribution patterns. Further, since the impact elastic pressure can be obtained easily and safely, it is possible to make a full-scale application in a wide industrial field such as a processing field.
