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:
A rotary wire stripping machine for removing insulation from the end of an insulated wire including a reciprocating carriage for supporting a rotating head member which has a pair of cutting blades and a guide means for positioning the end of the wire to be stripped. The rotating head member includes a central chamber for receiving the end of an insulated wire and cam means for forcing the blades into contact with the wire to cut the insulation when the carriage is moved to a first position and to pull the insulation off the end of the wire when the carriage is moved to a second position. The machine also includes a means of securely clamping the wire and a means for straightening the wire so that it may be received within the rotating head member.
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.
Abstract:
An apparatus for producing electrical wire leads has two feeding clamps which are counter reciprocated between a fixed control station and an adjustable control station whose spacing from the fixed control station determines the length of the produced wire lead. Varying the spacing between the control stations automatically varies the cycling of the apparatus as required for the increased or decreased length of the produced wire lead.
Abstract:
A wire feeding unit and an associated wire length measuring unit advance supply wire through a cutting zone and at the same time the advanced supply wire is guided by a wire transfer system across transversely spaced endless conveyor chains of a wire propelling conveyor. The feeding unit is automatically stopped when it has advanced a measured length of the supply wire and the transfer system tensions the advanced supply wire while it is held against lengthwise displacement by the stopped feeding unit. The wire transfer system then engages the stopped and tensioned wire length with gripping jaws on the conveyor chains, the gripping jaws are closed, and the supply wire is severed in the cutting zone. Tensioning of the advanced supply wire prevents it from sagging between the transversely spaced conveyor gripping jaws and thereby avoids undesirable length variations of the cut off portion of the supply wire. The mechanism for severing the supply wire in the cutting zone is laterally adjustable to clear the adjacent end of the cut off wire length during subsequent advance movement of the conveyor chains.
Abstract:
A conveyor system for transporting electrical wire leads to a terminal press having the terminal applicator enclosed within a safety shield, the system including an endless chain conveyor having a number of clamp assemblies and being mounted on a pair of sprocket wheels for transferring the wire leads from a load position to a position in register with the terminal applicator under the shield. A wire lead register is provided at the load position and a step-by-step precision drive mechanism accurately locates the pre-registered wire leads in the terminal applicator.
Abstract:
An endless chain having alternate pairs of inner and outer side bars moves in an oblong path around spaced sprocket wheels. Pairs of relatively swingable clamping jaws for electrical wire leads or the like are mounted at intervals on the chain and are nested between opposite side bars and associated hinge bushings thereof. Outwardly extending gripping arms of the jaws are spring biased toward each other and are temporarily swung apart into wire receiving and wire releasing positions by actuating fingers which project inward of the oblong path of chain travel and are engaged by cams at the sprocket wheels.
Abstract:
An automatic terminal applying machine including a pair of terminal applicators, a wire cutting and stripping assembly located between and in line with the applicators, a wire measuring unit, a wire feed assembly including a wire guide assembly to accurately align the wire in the cutting and stripping assembly, and a wire drag and discharge assembly for holding the wire during terminal application and discharging the wire from the assembly after terminal application to a collection trough or wire stacking device. The cycle of operation of each of the assemblies is controlled by a number of cams secured to a common drive shaft and controlled by a one revolution pin clutch. A clutch controlled loop assembly provides a loop in the wire to minimize drag movement of the wire guide tube.
