Abstract
Abstract A component lead wire cutting equipment includes upper and lower levers for gripping a pair of lead wires of an electric component extending in the same direction. A driving device moves the levers. A pair of cutter blades are mounted on the levers to spread the pitch of the lead wires to a given size, and to cut off the lead wires. A pair of regulating convex portions regulate the movement of the lead wires along their spreading direction in the position between the cutter blades and the component body. During the cutting operation of the lead wires the component is prevented from being broken or from being inclined in its body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
A component lead wire cutting apparatus of the type for cutting off end portions of lead wires extending in generally the same direction from the body of an electrical component and for shaping the remaining unremoved portions of the lead wires, said apparatus comprising: a cutter unit including first and second cutter blades movable toward each other to a closed cutting position and away from each other to an open non-cutting position; said first and second cutter blades having thereon cooperative cutting means for, with the lead wires of an electrical component extending between said first and second cutter blades, and during movement of said first and second cutter blades from said non-cutting position thereof to said cutting position thereof, spreading said lead wires away from each other and cutting off the outer end portions of said lead wires, whereby unremoved portions of said lead wires remain connected to the body of said electrical component; and regulating means for, during said spreading apart of said lead wires, controlling the extent of movement in the spreading directions of said unremoved portions of said lead wires, and thereby for preventing excessive spreading of said unremoved portions and breaking of said body.
Claim 2
Dependent Claim
199 words
A component lead wire cutting apparatus of the type for cutting off end portions of lead wires extending in generally the same direction from the body of an electrical component and for shaping the remaining unremoved portions of the lead wires, said apparatus comprising: a cutter unit including first and second cutter blades movable toward each other to a closed cutting position and away from each other to an open non-cutting position; said first and second cutter blades having thereon cooperative cutting means for, with the lead wires of an electrical component extending between said first and second cutter blades, and during movement of said first and second cutter blades from said non-cutting position thereof to said cutting position thereof, spreading said lead wires away from each other and cutting off the outer end portions of said lead wires, whereby unremoved portions of said lead wires remain connected to the body of said electrical component; and regulating means for, during said spreading apart of said lead wires, controlling the extent of movement in the spreading directions of said unremoved portions of said lead wires, and thereby for preventing excessive spreading of said unremoved portions and breaking of said body.
Claim 3
Dependent Claim
38 words
An apparatus as claimed in claim 1, wherein said cutter unit further includes first and second levers pivotally mounted at intermediate portions thereof and having connected to adjacent first ends thereof said first and second cutter blades, respectively.
Claim 4
Dependent Claim
18 words
An apparatus as claimed in claim 2, wherein said regulating means is a portion of said cutter unit.
Claim 5
Dependent Claim
39 words
An apparatus as claimed in claim 3, wherein said regulating means comprises a pair of projections on said first lever, said projections having inner facing surfaces abutting said unremoved portions of said lead wires during said spreading apart thereof.
Claim 6
Dependent Claim
36 words
An apparatus as claimed in claim 4, wherein said inner facing surfaces of said projections are spaced by a distance equal to or slightly greater than the original pitch, before said spreading, between said lead wires.
Claim 7
Dependent Claim
30 words
An apparatus as claimed in claim 4, wherein said regulating means further comprises a pair of recesses in said second lever to receive said pair of projections during said spreading.
Claim 8
Dependent Claim
19 words
An apparatus as claimed in claim 4, wherein said projections are positioned between said cutter blades and said body.
Claim 9
Dependent Claim
41 words
An apparatus as claimed in claim 1, wherein: said cutting means comprises a convex portion on said first cutter blade and a cooperative concave portion in said second cutter blade, said convex and concave portions being defined by cooperative cutting edges.
