Abstract: A material 1 to be shaped is reduced and formed by bringing dies with convex forming surfaces, when viewed from the side of the transfer line of the material 1, close to the transfer line from above and below the material 1, in synchronism with each other, while giving the dies a swinging motion in such a manner that the portions of the forming surfaces of the dies, in contact with the material 1, are transferred from the upstream to the downstream side in the direction of the transfer line.

Abstract: In a laser shock peening process, the shape of the spot generated by the laser beam is changed on the fly. This is achieved, for example, by a masking device which is movable into and out of the path of the laser beam. Laser shock peening spots can consequently be shaped so as to avoid the spots overlapping an edge of the workpiece, or any other feature which may be damaged by the laser energy.

Abstract: A refrigerant gas is collected and a compressor is removed from a discarded refrigerator, a heat-insulating housing including a heat insulator is cut/processed and separated into a plurality of pieces, and the pieces are compressed/processed by compression rollers opposing each other so as to collect a gas contained in the heat insulator. In accordance with this method, substantially no gas contained in the heat insulator is diffused at the time of cutting the heat-insulating housing, and the gas can be collected at a high concentration because it is collected by being allowed to leak out at the time of compressing. Furthermore, by using the compression rollers, closed-cells in the heat insulator can be crushed easily, thereby collecting the gas completely and reliably. Thus, it is possible to collect a foaming gas contained in the heat insulator efficiently and disassemble a refrigerator at low cost without increasing the size of equipment and an installation space.

A press plate is detachably secured to the press shaft.

Abstract: When an actuator is operated, an upper die is displaced downwardly, pressing a lower surface of a workpiece against a forming surface. After the upper die is displaced upwardly, an ejecting member is displaced upwardly to push the workpiece upwardly by a lower die. As the workpiece is displaced upwardly, an outer circumferential surface of the workpiece is squeezed by a squeezer projecting radially inwardly from an inner circumferential surface of an outer ring.

Abstract: The invention relates to a method for producing a torsional vibration damper housing, especially the housing for a viscosity torsional vibration damper, whereby the damper housing is manufactured from an existing plate circular blank and the shaping of the damper housing occurs in an impact extrusion machine during a non-cutting impact extrusion shaping method. In successive impact extrusion shaping steps, all parts of the damper housing protruding from the plane of the plate circular blank, which forms the housing rear wall, are impact extruded while reducing the wall thickness of said parts to form a one-piece damper housing. Said damper housing is structured such that the area of the fastening flange has the largest thickness.
