  • Patent number: 7287411
    Abstract: A die for a tool set includes at least one punch and a die which defines a cavity for effecting joining. The die comprises an anvil opposite the punch. Die segments adjoin the said anvil and define the cavity in the circumferential direction. When the punch is being fed in the direction of the anvil, the segments execute a yielding movement transversely to the punch feed direction.

  • Patent number: 6959582
    Abstract: An expandable forming tool has a body with a mounting stem on its upper surface and a transversely extending channel in its lower surface in which is slidably seated a wedge-shaped actuator for vertical sliding movement. The larger lower end normally depends from the body. A pair of slides are slidably seated in the channel on opposite sides of the actuator, and they have angular surfaces slidably bearing on the sloping surfaces of the actuator. Springs bias the slides against the side surfaces of the actuator, and a spring biases the actuator outwardly of the body. The actuator is driven vertically inwardly of the channel by movement of its larger end against a workpiece, and this inward movement pushes the slide members outwardly in the channel to project beyond the periphery of the body. The tool can produce contours in the workpiece, or cut the workpiece, or both.

  • Publication number: 20030188564
    Abstract: The present invention relates to a joiner (1) for lance joining ductile materials, such as metal sheets (7, 8), and in particular to a joiner including a die assembly (4) and a punch assembly (2). The die assembly (4) includes a die anvil (44) and an anvil surface (46). There are at least two die blades (56, 57) around the anvil (44), the blades extending in a longitudinal direction (10), generally above and below opposite sides (29) of the anvil surface (46) to form a die aperture (66) for the punch (2). Each blade (56, 57) is arranged to move away from the anvil (44) to openup the aperture (66) when ductile material (7, 8) is forced in the longitudinal direction (10) into the aperture (66) and against the anvil (44) by the punch (2). Each blade (56, 57) has a cutting edge (63, 64) above the anvil (44) facing towards the die aperture (66) for cutting through the ductile material (7, 8) to make a lance joint when the material is forced into the aperture.

  • Patent number: 6035521
    Abstract: A crimping apparatus for crimping a workpiece such as a terminal or eyelet around a core such as a wire or a fiber optic cable. The apparatus includes upper and lower identical plates supported for opposing reciprocal motion on respective upper and lower portions of a press. Each plate includes two crimp segments. Each crimp segment has an impingement surface. All four of the crimp segments are supported for mutually convergent motion relative to one another. The vertical motion of the two plates closing together drives both the vertical and the lateral components of the convergent crimp segment motion. The impingement surfaces of the respective crimp segments form a generally annular composite crimping surface for cooperatively crimping a work piece into an arcuate configuration around a core.

  • Patent number: 5259102
    Abstract: A clinching tool including a punch and a die. The die includes a sleeve, a riser, an elastomeric member, and a plurality of fingers. The riser is positioned within the sleeve and includes an upper reduced diameter anvil portion projecting upwardly through the open upper end of the sleeve. The spring fingers are positioned circumferentially around the anvil and are positioned at their lower ends within the sleeve against the outer periphery of the annular member which is positioned around the anvil beneath the upper anvil surface of the anvil portion of the riser.

  • Patent number: 5131258
    Abstract: A new punch anvil is provided for use with an axial punch for use in a fastening system of the kind in which the punch displaces a portion of one sheet member, such as a thin metal sheet, into another sheet to fasten them together, the punch and die cooperating to form a "button" of sideways displaced material that locks the sheets together. The anvil consists of two parts, one of which is of smaller transverse dimension than the other to form a transverse shoulder between them. The anvil end against which the members are clamped to be punched is surrounded by a jaw which is split longitudinally to be in at least two members held assembled by an encircling resilient ring or collar, so that the jaw members can move apart transversely and/or their upper ends in contact with the clamped members can rock apart on the shoulder to release them upon conclusion fo the fastening operation.

  • Patent number: 3971244
    Abstract: An impact tool for dressing metal sheets, particularly for repairing damaged vehicle bodies, has a tool carrier, in a bore of which there are guided at least two jaws separated from each other in the rest position of the tool by resilient elements, e.g. springs or rubber elements. The jaws are guided for a limited stroke between a rigid abutment formed by the front face of the tool carrier and a stop formed by a bolt fixed to the tool carrier and intersecting holes of the stems of the jaws with play. The jaws are loaded by at least one resilient element, e.g. a helical spring, abutted with its one end against the end of the bore of the tool carrier and with its other end against the inner end of each jaw. Surfaces having portions diverging in direction to the outer ends of the jaws force the jaws radially inwardly when the jaws hit the metal sheet to be treated.
