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 multiple opening panel press is described with a plurality of movable platens which are individually controlled to adjust the spacing between adjacent platens to a predetermined panel width. Position-sensor transducers are employed to produce control signals corresponding to the platen positions which operate control cylinders by associated valves to adjust the platen spacing. The transducers are preferably sonic waveguides which interact with permanent magnets fixed to the movable platens to generate platen position signals which are applied to an automatic control system which includes a computer that produces the control signals.

Abstract: Apparatus for compensating for eccentric loads in forging presses and the like. The apparatus includes a plurality of hydraulic cylinders positioned about the press and connected between the platens. The cylinders are interconnected through a hydraulic integrating device so that if there are eccentric forces acting on the platens the forces within the hydraulic cylinders are automatically shifted to counteract the eccentric forces.

Abstract: Molding compound parts with uniform wall thickness are precisely and repeatedly produced by compression, though supporting rods and levelling devices used for supporting the platen of press equipment which tilt during compression. The press equipment of the present invention is provided with levelling devices for supporting the platen at the four corners on the bed. The supporting rods of the levelling devices are hollow, with position detecting means vertically mounted therein so that the height of the supporting rods can be precisely detected and the rods can be synchronously controlled so as to make the upper mold half parallel to the lower mold half of the mold without magnifying the error caused by the inclination of the supporting rods.
