  • Patent number: 9669446
    Abstract: The die cushion force setting apparatus according to an aspect of the present invention allows die cushion forces (component forces) acting on plural driving shafts to be set easily, makes it easy to apply strong or weak die cushion forces to a complex-shaped drawn part in a plane of a cushion pad, and provides a smooth die cushion force distribution. An operator manually enters a total die cushion force, axial component force of a left front hydraulic cylinder, and center-of-force position by operating an input device. Based on the information entered via the input device, the numerical computing device B1 calculates axial component forces of three hydraulic cylinders through numerical computations. The one axial component force thus entered and three axial component forces thus computed numerically are set as the axial component forces of four hydraulic cylinders.

    Abstract: A variable hydrostatic track system for vertical lathes includes a plurality of sectors arranged between the periphery and the central opening of an annular base. Each sector includes an upper housing with a hydraulic fluid outlet such that when the injected hydraulic fluid overflows from the housings, it forms a film between the rotating chuck and the sectors. The track system further includes a positioning mechanism having a plurality of hydraulic cylinders fixed on the annular base in a radial direction between the central opening and the sectors. The rod of each hydraulic cylinder is coupled to a piston and to one of the sectors. Each sector is guided in a radial guidance element such that, due to the action of the hydraulic cylinder, the sector is movable between an inner radial position and an outer radial position.

  • Publication number: 20140013579
    Abstract: A method for mutually positioning tubes. End faces, which includes a generally annular and generally circular end surface near an inner surface of the tube and a beveled edge surface connecting the end surface to an outer surface of the tube, are provided on first and second tubes, respectively. Plural clamping cylinders are engaged with the first and second tubes, respectively. Each cylinder is radially arranged onto and evenly distributed around respective tubes. The first and second tubes are pre-positioned relative to each other such that their respective end faces are opposite each other. At least one radial offset is assessed between the respective end surfaces of the first and second tubes. The clamping cylinders of the first and/or second tube are moved relative to each other in accordance with the assessed radial offset based on an optimization of areas in which their respective end surfaces coincide.

  • Patent number: 8617409
    Abstract: A protective chuck is magnetically levitated on a substrate with a gas layer between the bottom surface of the protective chuck and the substrate surface. The gas layer protects a surface region of the substrate against a fluid layer covering the remaining of the substrate surface without contacting the substrate, reducing or eliminating potential damage to the substrate surface. The magnetically levitated protective chuck can enable combinatorial processing of a substrate, providing multiple isolated processing regions on a single substrate with different material and processing conditions.

  • Patent number: 8590873
    Abstract: A sheet restrainer is used to restrain movement of continuously traveling glass sheet and includes arms on either side of the glass sheet. A driving device coupled to the arms moves the arms from a retracted position in which the arms are withdrawn from the glass sheet to an engaged position in which the arms are near the glass sheet and in alignment with each other. Rollers are connected to the arms and contact the glass sheet in the engaged position. A damping device applies an adjustable damping force to at least one of the arms dampening movement of the arm in the engaged position thereby restraining movement of the sheet. In a method of operation, the damping devices restrain angular and/or lateral movement of the sheet by transmitting movement of the sheet against the rollers into a resistive damping force of the damping devices.

  • Publication number: 20130234382
    Abstract: The invention concerns a clamping system for the clamping of workpieces, wherein clamping means can be moved by a small spacing relative to a stationary affixing block, so as to be able to clamp a workpiece independently of a fastening grid prespecified on a machine tool or to compensate for a distance change between clamping components located on the workpiece, so that a zero point previously defined on the workpiece again coincides after a renewed clamping with clamping components whose distances were changed.
