  • Publication number: 20100229705
    Abstract: A method, and an apparatus, for operating a hydraulic shearing machine. For cutting a shearing-movement of at least one shear blade which is curved, starting from a starting-position under application of an overall actuating-force and for resetting of the shear blades which were moved for cutting to their starting-position after accomplishment of the shearing-movement, a reset-movement under application of an overall reset-force. The shearing-movement and the reset-movement are accomplished by a hydraulic actuating-mechanism comprising hydraulic cylinders, wherein the overall actuating-force and the overall reset-force being applied to the moved shear blades by at least one hydraulic cylinder of the actuating-mechanism. The magnitude of the overall actuating-force is adjustable by switching one or several hydraulic cylinders of the actuating-mechanism in and out of operation-mode.

  • Patent number: 4355558
    Abstract: The invention relates to a pair of shears for shearing sheet metal. Known shears, for example power shears, require relatively great forces, which cannot be produced except by special gear means. For rendering it possible to manually shear even relatively thick sheets, according to the invention it is proposed that the movable blade (22) of the shears is connected to a drive mechanism (13,15,17) and is located above the stationary blade (6) of the shears in its starting position for shearing, and that the drive mechanism is supported in the stand (1) of the shears for vertical movement, whereby the dead load of the drive mechanism and of the movable blade is utilized by gravity action for the shearing work.

  • Patent number: 4277996
    Abstract: The present apparatus applies force along a line or to a surface through one or more linear or rather longitudinal, elastically expandable or deformable members. The expansion of the elongated member, such as an elastic, reinforced hose or membrane, is transmitted to the tool proper, for example, a strip steel knife or a clamping device, along the entire length of the tool, whereby a linear force application is achieved. Several of such members may be arranged in parallel to obtain substantially a surface area force application. The force application member may also be curved for applying the force, such as a cutting force to an equally curved tool such as a strip steel knife. The force application member is returned to its starting position after a work stroke is completed. The work stroke is performed by expanding the member with the aid of a medium under pressure. The return is accomplished by a spring force or by a similar expansion member.

A jump wheel is provided on a first arm pivotally mounted in the head, which head may comprise a trolley structure, and a scoring tool is mounted in a pivoted second arm having its pivot on the first arm. A spring acts between the first and second arms to bias the scoring tool to a limit position, defined by a suitable stop, such that the force of the scoring tool on the surface of the glass is independent of vertical displacement of the scoring tool as it traverses the sheet. The first arm is also spring biased to maintain contact between the jump wheel and the glass surface.
