  • Patent number: 8800134
    Abstract: The present invention relates to a positioning device for positioning an element to be crimped in a crimping tool, for example a wire end sleeve or an electrical connecting plug. The invention further relates to a crimping tool for crimping a connecting element to be situated in a pressing axis. To allow the element that will be crimped to be brought into the pressing axis, the positioning device has a retaining unit for retaining, about its periphery, the element that will be crimped. The retaining unit has a retaining opening which encompasses the pressing axis coaxially. The positioning device further permits the positioning of the element that will be crimped within the pressing axis, in order, in particular, to ensure the necessary insertion depth of the element to be crimped in the crimping tool. For this purpose, the positioning device of the invention has an axial stop, with which the position in the pressing axis of the element to be crimped can be defined.

  • Patent number: 5732588
    Abstract: The invention pertains to a double press for forging round or edged bar-shaped workpieces using two presses set at 90.degree. to each other, each having a pair of forging tools (A1, A2, B1, B2) that hydraulically work pairs I and II of the forging tools being driven alternatingly and each of the pump assemblies (5,6) being connected on its delivery side to a piston-cylinder unit (1,3) of a forging tool (A1, A2) of the one pair I and on its suction side to a piston-cylinder unit (2,4) of a forging tool (B1, B2) of the other pair II, and with the main lines (21, 22, 23, 24) between the pump assemblies (5,6) and the piston-cylinder units (1, 2, 3, 4) being free of valves. The delivery direction of the pump assemblies (5,6) is reversible, so that the pumps' delivery and suction sides change with a reversal of the delivery direction.

  • Patent number: 5400634
    Abstract: A method and apparatus for forming a length of tubing into a curved, unbalanced and non-uniform shape continuously bends the tubing and then changes the cross-sectional shape along the length of the tubing to eliminate springback and provide a stable part with shape retention. The apparatus includes relatively movable upper and lower half die shoes. A form post, a forming steel subassembly, a plurality of slides and driver posts are positioned on the shoes in Juxtaposed relationship. A clamp holds a length of tubing against the form post. Movement of the die shoes towards each other shifts the slides to continuously bend the tube about the form post. After the bending operation, the cross-sectional shape of the tubing is changed from a generally circular shape towards an oval or generally rectangular shape. A pressure is applied to induce stresses which eliminate springback and provide a stable part.

  • Patent number: 5287721
    Abstract: Apparatus for forming curved needles from needle blanks of differing sizes and material characteristics having a guide die, driven by a linear actuator, for biasing the needle blank against a forming surface. Bending dies also driven by linear actuators are provided for bending the ends of the needle blank around the top of the forming surface. Adjusting micrometers are provided to adjust the contact point at which the bending dies contact the needle blank. The apparatus can therefore be readily adapted for differing needle stocks. The entire bending process is automated so that uniform needles may be rapidly produced.

  • Patent number: 5186036
    Abstract: An electric cable bending device for bending an exposed portion of core wire of electric cable having a coating member mounted on a non exposed portion of said core wire has a clamping unit, a vertical hot press, a horizontal hot press, and a vertically supporting unit. The clamping unit clamps the electric cable such that the exposed portion of core wire is located at a position under the vertical hot press and between the supporting unit and the horizontal hot press. By the down stroke of the vertical hot press, the exposed core is heated and bent perpendicularly. The supporting unit supports the cable against a pushing force generated during the stroke of the horizontal hot press, while the perpendicularly bent exposed core is heated and bent back toward another end of the electric cable. As a result, thus bent core wire is firmly and tightly bent in a U-shape for ensuring the complete electrical contact with the terminal lug which will be provided in the following process.
