る。In this apparatus, the combustion chamber has an inverted conical shape, and the cross-sectional area is set to gradually decrease from one end as the flame progresses, and the other end has a converging portion having a minimum cross-sectional area. The liquid surface of the hydraulic chamber as a pressure chamber faces the opening of the other end formed. As the flame in the combustion chamber progresses, the cross-sectional area of the combustion chamber becomes smaller, so the pressure rises,
Very high pressure at the other end. This high pressure is converted into the hydraulic pressure of the liquid in the hydraulic chamber. Further, if a processing chamber having a mold is provided in the hydraulic chamber and a member to be processed such as a plate member whose peripheral edge is fixed by a pressing member is bolted on the mold, the liquid pressure causes the mold to move to the mold. Processing can be performed along a predetermined shape. Further, the pressure chamber may be an elastic pressure chamber having a rubber-like elastic body instead of the liquid.

なる。In the case of processing by the above-mentioned detonation pressure, wrinkles are prevented by pressing the peripheral edge of the member to be processed with a pressing member when forming a non-processed member such as a plate material. The structure is such that, for example, a spacer is installed between the flange portions for connecting the pressure chamber and the processing chamber, and the member to be processed is fastened to the spacer with bolts or the like before being fixed, and then the molding is performed.

As a result, even if the generation cycle of the shock wave due to the detonation, that is, the processing cycle is shortened and the mass productivity is not improved, the purpose cannot be achieved even if it takes time to fix the member to be processed. Further, the pressing force of the pressing member must be adjusted depending on whether the forming is bulging or deep drawing, and in those cases, the pressing force of the pressing member must be adjusted according to the forming shape and size of the member to be processed, but the fastening with the bolt cannot handle this.

Further, by appropriately changing the shape of the abutting member 36, it becomes possible to cope with different processing degrees depending on the shape or site of the member to be processed. <Third Embodiment> In the first and second embodiments, the rod of the cylinder device moves in and out in a direction perpendicular to the workpiece P, but in this embodiment shown in FIG. It is characterized in that it is parallel to the member P. In the present embodiment, the pressing member has an abutting member 40 having a tapered surface and a pressing drive member 39 having a tapered surface that matches the tapered surface of the contact member 41, and the pressing drive member 39 is the member to be processed. P
Rod 38 of the cylinder device 37 that appears in and out in a direction parallel to
It is attached to the tip of the. In the device of this embodiment, when the rod 38 is ejected, the pressing drive member 39 abuts the driving force in the moving direction of the rod 38 based on the wedge action between the taper surface and the taper surface of the abutment member 40. Not only can the member 40 change the direction in which the member P is pressed to transmit the force, but also the transmission force can be increased. Therefore, the degree of freedom of the installation position of the cylinder device can be increased and the size can be reduced.

The present invention is not limited to this.
It may be of a lateral type with a reduced cross-sectional area in the lateral direction as disclosed in 926. In the case of a horizontal type, for example, a flame is used as a combustion chamber in which a wall surface having a substantially spherical bulge protruding toward the interior is formed on the upper surface or the lower surface of the cylindrical chamber to reduce the spatial cross-sectional area from the peripheral portion to the central portion. The compression chamber may be converged from the peripheral portion toward the central portion, and the compression chamber may be exposed at the lower portion of the central portion.

In addition, by changing the holding force of the holding means, it is possible to easily deal with the processing status of the member to be processed. If the receiving member of the holding means is provided with through-holes communicating with both sides of the workpiece, the degree of vacuum on both sides will be the same and undesirable deformation due to pressure difference will not occur and the molding accuracy will be improved.
