  • Patent number: 11059136
    Abstract: A workpiece holder device for a machine tool has a holder, which has a support part and a holder part. The support part supports the holder on a support device, preferably so that the holder can rotate about an axis of rotation. The holder part is set up to hold a workpiece directly or indirectly. To avoid, or at least minimize deviations from a desired alignment of the holder part based on elastic deformation of the holder due to the weight force of the workpiece, the holder has at least one mechanical or hydraulic pretensioning device arranged on or in it. The pretensioning device can be used to pretension the material of the holder, so that the pretensioning device applies a tensile stress or a compressive stress to at least one part of the holder. This can counteract a deviation of position due to an elastic deformation of the holder.

    Abstract: Method and apparatus for lamination of substrates, e.g. rigid plastic layers, to manufacture laminated products. The methods include the sequential application of vacuum and mechanical force through a two-stroke process performed by a lamination apparatus having one or more force-producing stroke cylinders. Actuation of a cylinder to produce a first stroke creates a sealed chamber within the apparatus, enclosing a stack of substrates to be laminated. The sealed chamber may be evacuated of air by application of a vacuum. Subsequent actuation of a cylinder to produce a second stroke applies mechanical force to the sealed chamber, which compresses the substrates into a laminated product substantially free of air bubbles or voids.

  • Publication number: 20130333578
    Abstract: Assemblies and methods for processing a workpiece in a ram-driven press employ an active tool contained by a housing that is interchangeable with a passive forming tool assembly in a mounting assembly of the press. The active tool includes a microprocessor and a functional head coupled to the microprocessor. Some assemblies including the active tool include a switch for activating the functional head; the switch may be mounted to the housing such that, when the housing is mounted in the mounting assembly of the press, the switch is triggered by movement of the housing in response to the ram stroke of the press.

  • Patent number: 8522595
    Abstract: A guided keeper assembly for metal forming dies includes a base having a mounting face and a fastener aperture to mount the base to an associated die shoe, as well as a central guide aperture. A guide pin having a central portion is closely received in the central guide aperture for precisely guiding reciprocal motion between the die pad and the die shoe. The guide pin has an enlarged head at one end which abuts the the-base to positively limit travel between the die shoe and the die pad, and a shoulder at an opposite end with an alignment mechanism that precisely locates the guide pin on the die pad. A fastener extends through the fastener aperture in the base to securely connect the same with the die shoe. Another fastener securely connects the second end of the guide pin with the die pad.

  • Publication number: 20130199385
    Abstract: Exemplary presses, e.g., for applying indicia to garments by application of heat, are disclosed. For example, a press may include an upper platen, and a lower platen disposed below and generally aligned with the upper platen. The press may further include a support head adapted to move the upper platen between an open position, wherein the upper and lower platens are spaced away from one another, and a closed position, wherein the upper platen is pressed against the lower platen. In some exemplary approaches, the support head may extend from an axial support of the press. The support head may be configured to rotate about the axial support while maintaining the platens in a parallel alignment with one another as the support head rotates about the axial support. In some examples, the operation of the press is generally automated.

  • Publication number: 20130118364
    Abstract: An electric servo press machine is configured to convert a rotation of an electric servomotor into a reciprocating linear motion of a slide to perform press working on a workpiece. The machine includes a clutch mechanism interposed in a power transmission path between the servomotor and the slide, and a brake mechanism for applying a brake onto the slide under a disconnected state in which the servomotor and the power transmission path are decoupled from each other by the clutch mechanism. The machine brings the clutch mechanism into the disconnected state and applies the brake onto the slide upon an immediate stop request, and recovers from immediate stop under a state in which a phase shift between the servomotor and the power transmission path ranging from the clutch mechanism in the disconnected state to the slide is eliminated under a connected state of the clutch mechanism.

  • Publication number: 20130025475
    Abstract: A press, a method for operating the press, and a lubricating arrangement for the press or for another working machine. The press comprises a press drive that is connected with a ram of the press, which ram can be moved via a transmission in a working direction (Z). The transmission comprises at least one sliding bearing with one and, preferably, several lubricating points. In a first press operating state, all the lubricating points of the sliding bearing are supplied with lubricant at a first lubricant pressure (p1). In a second press operating state, the thickness of the lubricant film formed in the sliding bearing drops below a minimum value in the region of at least one first lubricating point and lubricant is supplied thereto at a second greater lubricating pressure (p2) in order to prevent increased wear of the sliding bearing.
