    摘要： An apparatus for providing a reciprocating motion. The apparatus has a housing block that contains twin piston guides in spaced apart relationship to one another. The piston guides each contain a piston that has a gear rack. The gear racks are connected by a pinion gear so that the movement of one piston will cause an equal and opposite movement of the other piston. The movement of the pistons is controlled by the application of a fluid pressure to one or both of the pistons. The travel of the pistons is limited by a mechanical stop at one end and a fluid cushion device at the other end. Tools for the altering of a workpiece may be attached to one or both ends of the pistons. In one embodiment, the apparatus is subjected to a rotary displacement achieved through the linear motion of one of the pistons.

    摘要： A machine for cutting a block of stone material into slabs, comprising a bandsaw provided with a blade movable along a plane of cut and a carriage able to support the block and to cause its approach motion towards the blade. This blade passes over two fly-wheels one of which is driven, mounted on a body which is oscillatable with respect to a base of the saw; the body is provided with a template cooperating with an inclined plane fixed to the base and is alternately movable on this under the thrust of a pair of hydraulic actuators.

    摘要： A hydraulic fluid shock dampening system is disclosed for a shearing press to minimize shock and vibration imposed on the press following breakthrough of the material being sheared by cutting die components carried by the press bed and slide. The system includes cylinder and piston units interposed between the press bed and slide each providing a variable volume fluid receiving chamber from which fluid under pressure is expelled during movement of the slide toward the bed to achieve a shearing operation. A flow sensitive shutoff valve is responsive to accelerated movement of the slide upon breakthrough to block fluid flow from the chambers and thus restrain further slide movement toward the press bed. In preferred structural embodiments of the system, the cylinder and piston units, shutoff valve and fluid pressure accumulator components are structurally associated with a bolster plate mountable on a press, or with die components mountable on a bolster plate.

    摘要： A machine for shearing sheets of metal. The machine has an upper knife movable toward a fixed lower knife with the cutting edge of the upper knife being positioned at an angle with respect to the cutting edge of the lower knife. A pair of hydraulic cylinder motors force the upper knife toward the lower knife with the point of intersection of the cutting edges being moved progressively along the length of the knives. A pair of links have proximal ends pivotally connected to the machine frame and have distal ends pivotally interconnected. Each link is pivotally connected to the upper knife so as to maintain a constant angle between the cutting edges during movement of the upper knife. Adjustment means are provided to preset the angle between the cutting edges.
