Wire Straightening Patents (Class 140/147)
  • Patent number: 5010642
    Abstract: The method of making a flat wiring harness consists of a pre-shaping process, a shaping process, and a wire bonding process. In the pre-shaping process, the intertwined wires are combed to be smoothed and straightened out and are pushed by a press block into parallelly arranged grooves in a series of longitudinally lined jigs and kept therein by a cover. In the shaping process, the group of wires thus laid in parallel lines in a series of the grooved jigs are shaped into a desired pattern of the flat wiring harness by moving any desired grooved jigs horizontally along guide slots formed in a holder plate, on which the grooved jigs and associated components are mounted. In the bonding process, the shaped flat wire group is applied with adhesive on one side through a screen which is patterned according to the shape of a final flat wiring harness. As the adhesive hardens, the wires are bonded together and a flat wiring harness of a desired two-dimensional shape is obtained.

  • Patent number: 4977934
    Abstract: A compact wire straightener module having a plurality of curved tubes for simultaneously straightening a large number of wires. Each tube bends its wire in a first plane and then bends the wire in a second plane perpendicular to the first plane. The wires are not pulled through the wire straightener module; but rather, after one end the wires has been secured, the wire straightener module moves in a horizontal direction along the wires to perform the straightening operation. This movement of the wire straightener module allows for use in a compact automatic cable assembly by eliminating the need for a separate mechanism to pull the wires through the wire straightener module. Further, each tube is a continuous assembly so that threading wire through the module is simple and fast.

  • Patent number: 4957146
    Abstract: A flatpack lead forming, cutting, and straightening machine. The flatpack is unloaded from the carrier and aligned for later processing by its leads, rather than the body portion. The first processing step forms the lead by bending them downwardly against an anvil, and then bending them outwardly to form the foot. The leads are cut by an upwardly-moving cutter to prevent downward flagging of the leads. The flatpack is then placed between two vertically mounted plates such that one set of plates contacts a pair of leads disposed on opposite sides of the flatpack body. The plates are moved upwardly and downwardly to flex the leads and remove the set therein. Adjacent lead pairs are flexed 180 degrees out of phase in this process. The formed, cut, and straightened flatpack is then loaded into a handling tube for storage or transport to the assembly area. A transport mechanism transports the flatpack from each stage of the process to the next stage.

  • Patent number: 4791271
    Abstract: A capstan drive assembly for electric arc welding receives filler wire which can have an undetermined cast to the wire. The assembly provides for self feeding of the wire from the inlet completely through to a welding torch. No portion of the assembly must be opened or disassembled to feed the filler wire. The wire is captured in a groove on the periphery of a capstan and held in place by spaced apart pressure rollers which serve to impart a predetermined cast to the filler wire. The predetermined cast overcomes any previous cast which was present in the wire. After the wire has received this cast, it is directed between opposite sides of wire straightening rollers which serve to bend the wire in the opposite direction of the predetermined cast and apply sufficient force to counteract the set cast. This apparatus and procedure results in producing a filler wire which is substantially straight.

  • Patent number: 4566503
    Abstract: This invention provides an apparatus and method of setting up apparatus for the automatic cutting and/or shaping of IC components carried in a tubular carrier and advanced for processing by gravity. A base plate is disposed at an angle of approximately forty degrees to the horizontal and provides a supporting means for gravitational feeding of these components from a removable U-shaped retainer to a guide and then to a die station. At this die station a resiliently tired feed wheel engages the body of the IC component which is metered and advanced with an intermittent motion. This motion is provided in a timed relationship with two rotating shafts which have pins moved in a precise orbit around a shaft centerline. These pins are one-hundred-eighty degrees out-of-phase with each other. The rotated feed wheel and attached tire are intermittently moved in a strict timed relationship to the movement of the two shafts by a one-way clutch driven by one of the shafts and by an eccentrically moved Pitman arm.

  • Patent number: 4397341
    Abstract: A coordinate array of terminal pins are straightened and aligned in precise rows and columns by flexing one-half of the pins in one direction while flexing the other half of the pins in an opposite direction. This coordinate alignment is attained by inserting first rows of pins (13) into apertures (31) formed in a first set of slide bars (36) and second rows of pins (13) into apertures (32) formed in a second set of slide bars (37) which are interleaved with the first bars. A pair of air cylinders (81 and 89) are programmed to operate to reciprocate the slide bars (36 and 37) in opposite directions to flex the terminal pins beyond elastic limits and back to their origin point. The flexing operation is effective to align the pins in a coordinate array without introduction of detrimental stresses in a terminal pin support, such as a connector housing (11) or a printed circuit board (102).
