  • Wind power generator with biased transmission arrangement
    Patent number: 7541686
    Abstract: In a wind power generation installation comprising a rotor with rotor blades mounted on a tower and connected via a transmission to a generator for generating electric power, an electric machine operable as a motor is also connected to the transmission for applying a driving torque to the transmission so as to bias the transmission so as to hold the gears of the transmission in constant engagement in order to prevent the detrimental effects of torque variations on the gears of the transmission.

  • Transfer arrangement and method
    Patent number: 7287950
    Abstract: In a transfer arrangement and method for transferring a workpiece between first and second spaced locations along a guide rail with a carriage movably supported on the guide rail, a transfer arm is pivotally supported on the carriage and carries at its free end a workpiece holder which is accelerated by the carriage with the arm essentially stretched out in the movement direction out of, and decelerated into, the end positions, and, in an intermediate position, the carriage movement is slowed down or even reversed while the workpiece holder is moved along by a pivot movement of the arm.

  • Press with cutting shock dampening
    Publication number: 20070101841
    Abstract: To increase the cutting quality and to improve the operation of a press, in particular in punching high-strength martensitic materials or when punching thick sheet metal, a sheet metal holding device is provided for securely clamping the respective workpiece during the punching operation. The clamping force is increased to 40% or more of the ram force. The force exerted by the sheet metal holding device during the penetration of the workpiece can be further increased. The increase in the clamping force preferably takes place in a controlled manner as a function of the press angle.

  • Transfer press with improved use of space
    Patent number: 7159438
    Abstract: A transfer press provided with a transfer device, having transfer units provided with cross members (37) for which the length is shorter than the width of a tool. The transfer units (29 to 32) are arranged completely between the processing stations or stages, are mounted on the crown or head piece, and are not provided with elements extending beside the tools or between supports of adjacent processing or press stations. Thus, the full width spanned by the press supports can be used for the tools. In addition, tools can be used which are provided with guides, effective between the upper tool and the lower tool, particularly in the side region. The work pieces are handled solely by means of the openings, freed by the tools and pointing counter to the transporting device, wherein no element of the transfer device extends past the side limits of the tool.

  • Overload safety device in a press
    Patent number: 7024991
    Abstract: In an overload safety device in a press, having a driving device with a drive shaft, a slide carrying out an oscillating movement and a connecting rod which connects the drive shaft with the slide and has a large and a small eye, the connecting rod is provided with a pressure element disposed displaceably in the longitudinal direction of the connecting rod. The pressure element acts at least indirectly upon a fluid such that, when a certain force acts upon the connecting rod, a pressure increase occurs in the fluid. The fluid is guided to a pressure limiting valve which, when a predetermined pressure is exceeded, causes an interruption of the slide movement.

  • Pneumatic cylinder with safety device
    Patent number: 6997102
    Abstract: A pneumatic force-generating device, for example, a pneumatic cylinder for balancing the ram weight on a press, is provided with an impact or catching device having an impact plate (24) for catching the piston (18) upon discharge of the weight. The deformable impact plate (24) is securely clamped along its edge or held by a clamping device (31), that permits a controlled slipping through. The impacting piston (18) deforms the impact plate (24) to absorb the kinetic energy produced if this piston is released as a result of damage and is accelerated by the existing gas bolster and thrown against the impact plate (24).
