Abstract: Method of correcting a bending operation performed by a press brake, the bottom beam of which contains deformation compensation cylinders, in which a calibration nomogram is pre-recorded using very short calibration pieces, this nomogram establishing a correspondence between the forces measured at the side frames and the pressures applicable to the compensation cylinders in order to keep the bottom beam substantially straight. During a subsequent bending operation, pressure values resulting from this nomogram are applied to the compensation cylinders according to the forces measured at the side frames. A bottom dead centre is recalculated by taking account of the deformation of the top beam, the deformation of the side frames, the actual length and thickness of the piece, and the spring effect.

Abstract: A press working machine includes base members having concave portions, slider members arranged in the concave portions, link arms attached to first ends of the slider members respectively, and cylinders attached to the arms, for bending and extending the same. Furthermore, press members having curved mold-facing surfaces are arranged on the slider members. Molds having deformable structures are arranged on the press members. A workpiece is inserted between the molds, to be press-worked. The slider members are actuatable to press the press members against the molds, so as to deform the molds into different mold shapes. Thus, it is possible to press-mold workpieces into a plurality of shapes with a single mold assembly, thereby reducing the cost for manufacturing the mold assembly, omitting an operation of exchanging the mold assembly, and reducing the manufacturing cost.

Abstract: In a press for forming a long and narrow plate or strip of metal or synthetic resin into an elongated beam having an L-shaped section, of the type having a lower fixed frame provided with a female die on the top thereof and a hydraulically operated upper movable frame provided with a male die on the bottom thereof, a long space adjacent and parallel to the lower surface of the movable frame is provided in the movable frame. In the space are provided a plurality of small hydraulic deflection cylinders with pressure-fluid paths connected to the pressure-fluid paths of the main hydraulic cylinders to drive the movable frame. The space provided with a plurality of the small hydraulic deflection cylinders is so located that the center portion of the lower part of the movable frame is deflected counter to the deflection of the movable frame under press-forming load. When hydraulic pressure fluid is supplied to the main hydraulic cylinders to drive the movable frame for forming the plate by means of the dies fitted on the frames, the pressure fluid is also supplied to the plurality of the small hydraulic deflection cylinders in the space of the movable frame and the primary deflection of the frames under load is compensated for, so that a beam of L-shaped section free from convex or concave warp at its center portion is produced.
