Abstract:
Insulated electrical wires are successively advanced sidewise by an intermittently operated endless conveyor, and a wire cutting and stripping apparatus is provided at least at one side of the conveyor for trimming and stripping successive wires during periods of momentary standstill of the conveyor. The wire cutting and stripping apparatus has a reciprocable tool slide and complementary pairs of wire cutting and insulation stripping blades thereon. One of each pair of blades is rigidly mounted on the tool slide, and the other blade of each pair is reciprocable so that it is necessary to move only the reciprocable blades in order to cut the wire and score its insulation. A telescopic, springloaded connecting rod between a rotating crank shaft and the reciprocable cutting and stripping blades provides a dwell period during which the tool slide is retracted without opening the stripping blades. A knock-out mechanism dislodges the strippings from the rigidly mounted blades as well as from the reciprocably mounted blades.
Abstract:
A terminal applicator for attaching an electric terminal to the end of an insulated non-metallic ignition type wire having one or both ends of the wire insulation stripped to expose a short section of the non-metallic conductor. The wire is conveyed in a step by step manner to the terminal applicator. The applicator includes a die set having a movable die and a fixed die. The movable die includes a pusher plate which is moved downwardly with the movable die to partially bend the exposed conductor at the end of the wire downward into the path of motion of the movable die. The whole terminal applicator is moved toward the wire to seat the end of the wire in the terminal ears of an electric terminal. The motion of the applicator is used to bend the downwardly bent conductor back against the outside surface of the insulation so that on crimping of the terminal ears around the insulation, the exposed end of the conductor of the wire will be in electrical contact with the terminal.
Abstract:
An apparatus for transferring a pair of parallel electric wire lengths from a measuring, cutting and stripping machine to a precise location with respect to a first terminal applicator and a second terminal applicator. The apparatus includes a pivotally mounted conveyor assembly in which the conveyor end closest to the cutting and stripping machine is movable in the vertical plane up into the path of the horizontal wire in the cutting and stripping machine, and down from said path a like amount. A plurality of wire length carrying clamps are mounted on the conveyor assembly for lateral movement between a pair of conveyor chains to predetermined positions with respect to the cutting machine and the applicators. A mechanical linkage is operatively connected to coordinate the pivotal movement of the conveyor assembly, the operation of the drive mechanism for the conveyor chains and the opening and closing of the clamps with the operation of the cutting and stripping machine. A wire length gatherer is provided around the end of the conveyor assembly.
Abstract:
Insulated wire stock is gripped at longitudinally spaced portions by a pair of clamp assemblies and cut in two by a wire and insulation cutting assembly between the clamp assemblies. The relatively adjacent ends of the cut wire are pulled apart by the clamp assemblies so as to strip the cut insulation therefrom and bring the stripped wire ends beyond a pair of terminal crimping assemblies at opposite sides of the cutting assembly. Reverse movement of the clamp assemblies then brings the stripped wire ends into the crimping assemblies, and after terminals have been attached to the stripped wire ends, the stock and severed wire length are released and reverse movement of the clamp assemblies is continued to bring them back to their starting positions. A wire transfer mechanism and slotted bracket collect successively cut off wire lengths to which terminals have been attached. Brushes suppress whipping of the moving wire stock.
Abstract:
A rotary wire stripping machine for stripping a predetermined length of insulation from the end of a wire and, in the case of stranded wire, twisting the strands to form a finished end. The machine provides for accurate adjustment of the depth of cut of the insulation and of the twisting mechanism to accommodate a variety of wire and insulation diameters. The machine operates at very high speed in repeated cycles with provision being made for holding the wire stationary during the time that the insulation is being cut and removed from the wire and during the time that the wire strands are being twisted during each cycle of operation.
