An improved apparatus for cutting and stripping insulated wire. The apparatus includes a pair of cutting and stripping units which are mounted on a supporting structure in opposed relation and each cutting and stripping unit includes a central cutting knife and a pair of stripping knives, spaced laterally on opposite sides of the cutting knife. The insulated wire is fed between the cutting and stripping units and when a predetermined length of wire has been fed, the cutting units are moved toward each other in a first stroke of movement to cause the cutting knives to cut a length of wire. The wire and the cut length are then moved axially away from each other by gripping units in a first stroke of movement to position the cut end of the wire and the end of the cut length between the cutting knives and the respective stripping knives. The cutting and stripping units are then moved toward each other in a second stroke of movement to cut the insulation, and the gripping units are subsequently moved in a direction away from each other in a second stroke of movement to strip the insulation from the cut end of the wire and from the cut length. A mechanism is provided for adjusting the first stroke of movement of the gripping units to adjust the strip length and a second adjusting mechanism is included to adjust the stripping stroke of the cutting and stripping units to accommodate different gauges of wire.
An apparatus for cutting and stripping insulated wire, comprising a supporting structure, a pair of cutting and stripping units mounted on the supporting structure, each cutting and stripping unit including a central cutting knife and a pair of stripping knives spaced laterally on either side of said cutting knife, means for feeding an insulated wire downstream between said cutting and stripping units, first means for moving said cutting and stripping units in a direction toward each other in a first stroke of movement to cause the cutting knives to sever the wire and provide a cut length, a pair of gripping units, one of said gripping units located upstream of said cutting and stripping units and disposed to grip said wire and the other of said gripping units disposed downstream of said cutting and stripping units and disposed to grip said cut length, second means for moving said gripping units in a direction away from each other in a first stroke of movement to position the cut end of said wire and the cut end of said length at a location between the cutting knife and the respective stripping knife, third means for moving the cutting and stripping units in a direction toward each other in a second stroke of movement to cause said stripping knives to sever the insulation on the wire and on said length, and fourth means for moving said gripping units in a direction away from each other in a second stroke of movement to strip the insulation from said wire and from said length, said first and third means comprising a double fluid cylinder unit associated with each cutting and stripping unit.
An apparatus for cutting and stripping insulated wire, comprising a supporting structure, a pair of cutting and stripping units mounted on the supporting structure, each cutting and stripping unit including a central cutting knife and a pair of stripping knives spaced laterally on either side of said cutting knife, means for feeding an insulated wire downstream between said cutting and stripping units, first means for moving said cutting and stripping units in a direction toward each other in a first stroke of movement to cause the cutting knives to sever the wire and provide a cut length, a pair of gripping units, one of said gripping units located upstream of said cutting and stripping units and disposed to grip said wire and the other of said gripping units disposed downstream of said cutting and stripping units and disposed to grip said cut length, second means for moving said gripping units in a direction away from each other in a first stroke of movement to position the cut end of said wire and the cut end of said length at a location between the cutting knife and the respective stripping knife, third means for moving the cutting and stripping units in a direction toward each other in a second stroke of movement to cause said stripping knives to sever the insulation on the wire and on said length, and fourth means for moving said gripping units in a direction away from each other in a second stroke of movement to strip the insulation from said wire and from said length, said second means and said fourth means comprising a double cylinder unit associated with each gripping unit.
In an apparatus for cutting and stripping insulated wire, a gripping unit having a pair of cooperating gripping members to grip an insulated wire, first means for moving said gripping unit in an axial direction of said wire in a first stroke of movement and second means for moving the gripping unit in said axial direction in a second stroke of movement, said first and second means comprising a double fluid cylinder unit connected to said gripping unit.
In an apparatus for cutting and stripping insulated wire, a supporting structure, a pair of cutting and stripping units mounted on the supporting structure, each cutting and stripping unit including a central cutting knife and a pair of stripping knives each spaced laterally from the cutting knife, means for feeding an insulated wire downstream between said cutting units, first means for moving said cutting and stripping units in a direction toward each other in a first stroke of movement to cause said cutting knives to sever said wire and provide a cut length, second means for moving the cutting and stripping units in a direction toward each other in a second stroke of movement to cause the stripping knives to cut the insulation on the wire and on the cut length to provide cut slugs of insulation on the end of the wire and on the end of the cut length, and means for removing said slugs from the wire and the cut length, said first and second means comprising a double fluid cylinder unit associated with each cutting and stripping unit.
