  • Patent number: 8141482
    Abstract: A hydraulic fine blanking head for a mechanical press and an infeeding method for same. The hydraulic fine blanking head includes an adjusting mechanism having an adjusting nut provided with an internal motion thread engaged with external motion threads on a main cylinder, the adjusting nut being turnable around a stroke axis, a sprocket wheel rotatable at a frontal surface of the adjusting nut, a hydraulic motor driving the sprocket wheel, and a brake for the motor shaft. Axial backlash between the respective motion threads is prohibited by a pressure generated by a flow of pressurized hydraulic fluid which also generates a part forming force in the head. A conduit in communication with a hydraulic system and the interior of the head delivers the locking pressure, locking the threads against the backlash. Removal of pressure unlocks the threads. Infeed of the main cylinder with regard to the ram is adjustable by switching the motor and the brake on and off.

  • Patent number: 8042445
    Abstract: A cutting mold for removing two opposite superfluous rigid circuit boards from a rigid-flexible circuit board. A first cutter is connected to a first moldboard. A first barricade is connected to the first moldboard. The maximum vertical distance from the first barricade to the first moldboard exceeds that from the first cutter to the first moldboard. A second moldboard is opposite the first moldboard. The first and second moldboards move with respect to each other. A second cutter is connected to the second moldboard and corresponds to the first cutter. A second barricade is connected to the second moldboard and detachably abuts the first barricade. The maximum vertical distance from the second barricade to the second moldboard exceeds that from the second cutter to the second moldboard. The first and second cutters cut the superfluous rigid circuit boards when the first and second moldboards move toward each other.

  • Patent number: 7669511
    Abstract: A razor head has blade members with straight front cuffing edges which are mutually parallel and lie in a cutting plane. Imaginary median surfaces of the blade members are continuously curved from the cutting plane, from the cutting edges toward the rear edges. The razor has a handle with a pair of fork arms, the distal ends of which are connected to the head at positions adjacent the respective ends of the head. Each fork arm has a groove allowing pivoting of the distal end about a pivot axis parallel to the head axis but which does not pass through the razor head. Each groove is filled with a resiliently deformable material which is deformed when a pivoting force is applied to the razor head during shaving and which restores the razor head to a normal position when the force is removed.

  • Publication number: 20090266207
    Abstract: The safety device mainly contains a main controller, a detector, and an emergency braking member. The main controller contains a detection member connecting the detector, an alarm member producing visual or audible alarm, and a driving member for activating the emergency braking member to reverse or stop the motor of the machine tool. The detection member could be an electrostatic detection unit, or a capacitance detection unit, or a combination of the two. The detector is positioned on a top surface of a platform and in front of a saw of the machine tool. The detector could also be part of an axle of the saw so that the saw is effectively an extension of the detector and provides both cutting and safety functions.

  • Patent number: 6484613
    Abstract: A method of punching a via or through hole in a polymer-metal laminate workpiece in a punch press. The punch press has a punch tool, a driver coil for driving the punch tool through the polymer-metal laminate workpiece, and a stopper for stopping the punch travel of the punch tool and mechanically returning the punch tool to its starting position. The method includes the steps of applying an electrical current pulse through the driver coil to electromagnetically drive the punch downward to and through the workpiece, and then elastically colliding the punch tool with the stopper to stop and return the punch tool on an upward return stroke. Subsequently a second, braking pulse is applied through the driver coil to electromagnetically brake the punch. The second electrical current is applied after the start of the punching pulse, for a time and magnitude sufficient to brake the punch press.

  • Patent number: 6253652
    Abstract: In a web slitter of the type used for cutting continuous webs of material, such as paper, a top slitter assembly features a hub cylinder attached to its frame. The hub cylinder supports a freely rotating hub to which the top blade of the web slitter is mounted. The hub cylinder may be raised and lowered with respect to the slitter frame so that the top blade may be lowered to, and raised from, its cutting position. A toggle support is clamped to the hub cylinder while a pin holder is attached to the slitter frame. A toggle is attached to the toggle support in a pivoting fashion. Housed within the pin holder is a sliding pin and a compression spring. The compression spring resists the movement of the pin towards the hub of the web slitter. The pin may be extended so that it engages a notch in the hub. When the hub cylinder is raised, the toggle may be pivoted so that it abuts the end of the engaged pin against the action of the compression spring. As a result, the pin is maintained in engagement with the hub.

  • Patent number: 4994979
    Abstract: A system for preventing the collision of two cutting tools in a computer-controlled cutting unit in which the two cutting tools may at times be moved toward each other. This system determines the actual position of each cutting tool during the cutting process. The distance between the two cutting tools is determined and is compared with a previously specified tolerated separation by means of a comparator in the computer. As soon as the tolerated separation has been reached, the system shuts off the cutting unit. In addition, an electrical safety circuit prevents the cutting unit from starting up again automatically after an automatic shutdown.

  • Patent number: 4344551
    Abstract: An apparatus for transporting, cutting and dispensing heavy web sheet material such as cardboard, plastic film and the like, while in roll form. The apparatus includes a manually wheelable frame that can be selectively raised and lowered by a retractable handle at its rearward end to support the frame on a pair of front wheels for transporting the roll to the jobsite. Lowering the apparatus onto fixed rear legs supports the frame in a rest position for cutting and dispensing the sheet material. The frame has upright front and rear standards mounted in asymmetrical opposed relation on one side of the longitudinal center line of the frame. Thus, the roll is readily mounted in a stabilizing manner substantially along the frame center line by means of its roll axle shaft being supported on the inboard side of the standards.

    Abstract: A machine for punching a series of aligned holes in suitable stock, e.g., for forming binding holes in a stack of sheet material such as paper. The machine is electrically operated and generally includes a pressure bar which is guidingly constrained for movement along a vertical plane. A plurality of punches and coating dies are included and are arranged in a row and suitably attached to base structure directly beneath the pressure bar. Downward movement of the pressure bar is effective to drive the lower portions of selected ones of the punches into the respective dies and upward movement of the pressure bar is effective to return those driven punches, thus constituting one cycle thereof. A pair of lever arms are provided, having one of the ends thereof coupled to the pressure bar and being pivotally attached to the base and are suitably power driven by structure including a clutch which is operably coupled to the other ends of the lever arms for causing reciprocating movement thereof.
