  • Patent number: 4194541
    Abstract: A wire straightening apparatus includes a machine stand; a wire straightening device; a mounting for securing the wire straightening device to the stand; an inlet roller pair and an outlet roller pair; a mounting for securing the inlet roller pair and the outlet roller pair to the stand adjacent opposite sides of the wire straightening device for feeding a wire therethrough; and a drive for rotating the roller pairs. The drive comprises a first constant-volume hydraulic motor connected to at least one of the rollers of the inlet roller pair; a second constant-volume hydraulic motor connected to at least one of the rollers of the outlet roller pair; and an arrangement for supplying hydraulic medium under pressure to the motors.

  • Patent number: 4175459
    Abstract: A cutting apparatus for severing a wire continuously advanced through the apparatus along a wire path in a feeding direction parallel to the wire axis, comprises a carriage supported for displacement parallel to the feeding direction; two cutting members connected with the carriage; a support arm articulated to at least one of the cutting members; a displaceable anchor member to which the support arm is articulated by means of a support joint arranged on the support arm at a distance from the cutting member; a drive for moving the carriage in and opposite the feeding direction to cause, with the cooperation of the anchor member and the support arm, a motion of the cutting member in an arcuate path towards and, subsequent to severing, away from the wire and the other cutting member; and a force-exerting arrangement for shifting the anchor member to effect a displacement of the support joint and the support arm for affecting the course of the arcuate path of the cutting member.

  • Patent number: 4163363
    Abstract: Chain links are formed of wire pins by bending each wire pin about work faces of a mandrel with bending tools which engage the pin at the two end zones thereof. The locations of engagement describe, at least during the terminal phase of the bending operation, a circular involute, the reference point of which coincides with the center of curvature of the respective work face of the mandrel.

  • Patent number: 4158976
    Abstract: A wire cutting machine for consecutively severing predetermined wire lengths from a continuously fed wire of indefinite length, comprises a wire cutting device and a wire discharge device arranged downstream (as viewed in the direction of wire feed) of the wire cutting device. Th wire discharge device has a wire channel, the walls of which define an elongated channel space which is oriented in the direction of wire feed and within which the wire is advanced. In the channel wall a plurality of openings are provided which are arranged in the longitudinal direction at predetermined distances from one another. A wire length detecting arrangement is operatively connectible with the channel space through any selected one of the openings.

  • Patent number: 4078407
    Abstract: In order to accurately control a process in which a structural component of ductile material is subjected to a change in shape by the application of a progressively increasing deformation force while measuring the resulting deformation, the measured deformation is employed to derive a representation of a nominal deformation force which varies as a predetermined function of deformation over a selected deformation range, the representation is compared with the applied deformation force, and the application of the deformation force is terminated upon arriving at a deformation amount for which the applied deformation force coincides in value with the nominal deformation force.
