Abstract
An apparatus for simultaneously cutting wire segments having acutely angled ends from a plurality of wires including guide apparatus and feeding apparatus for the wires, and a cutting device comprising a base, reciprocable shear plate and clamp plate, each of which has parallel grooves therein, with each also having sliding surfaces that are at an acute angle to the axis of the grooves. A collection plate is also provided to contain cut segments and transfer the segments to a common collection point.
Claims13
An apparatus for simultaneously producing a plurality of wire segments having acute angled ends from a plurality of wires, comprising:
- (a) means for guiding said plurality of wires in a parallel relationship;
- (b) means for cutting said wires, adjacent said guide means, to simultaneously cut a segment from each of said plurality of wires, said cutting means having:
- (1) means for clamping said wires to be cut comprising a pressure pad and a confronting base member, both the pressure pad and base member having a plurality of grooves therein axially aligned with the guide means for said plurality of wires, said pressure pad having a first sliding surface and said base member having a second sliding surface coplanar with said first sliding surface,
- (2) means for shearing wire segments from said plurality of wires comprising a shear plate having grooves therein, axially aligned with the grooves of said pressure pad, and having a third sliding surface slidable along said first and second sliding surfaces of the pressure pad and confronting base member, all three of said sliding surfaces being at a common acute angle to the axes of said grooves, and
- (3) means for reciprocating said shear plate to shear portions of said plurality of wires and simultaneously form a plurality of wire segments;
- (c) means for intermittently feeding portions of said plurality of wires through the clamp means and past the sliding surfaces of the cutting means;
- (d) a segment supporting base, positioned adjacent said base member of the cutting means, having a smooth surface spaced from the grooves of said base member;
- and
- (e) a cover plate superimposed over the segment supporting base, the terminus of said cover plate being spaced from said base member of the cutting means, said cover plate having grooves therein coaxial with the grooves of said base member.
An apparatus for simultaneously producing a plurality of wire segments having acute angled ends from a plurality of wires, comprising:
- (a) means for guiding said plurality of wires in a parallel relationship;
- (b) means for cutting said wires, adjacent said guide means, to simultaneously cut a segment from each of said plurality of wires, said cutting means having:
- (1) means for clamping said wires to be cut comprising a pressure pad and a confronting base member, both the pressure pad and base member having a plurality of grooves therein axially aligned with the guide means for said plurality of wires, said pressure pad having a first sliding surface and said base member having a second sliding surface coplanar with said first sliding surface, said pressure pad having bores therein and a spring within each said bore,
- (2) means for shearing wire segments from said plurality of wires comprising a shear plate having grooves therein, axially aligned with the grooves of said pressure pad, and having a third sliding surface slidable along said first and second sliding surfaces of the pressure pad and confronting base member, all three of said sliding surfaces being at a common acute angle to the axes of said grooves, and
- (3) a reciprocable punch plate for reciprocating said shear plate to shear portions of said plurality of wires and simultaneously form a plurality of wire segments, said punch plate also bearing on the pressure pad and the springs therein to increase the pressure of said pad on wires situated in the grooves thereof;
- (c) means for intermittently feeding portions of said plurality of wires through the clamp means and past the sliding surfaces of the cutting means;
- (d) a segment supporting base positioned adjacent said base member of the cutting means, and having a smooth surface spaced from the grooves of said base member;
- and
- (e) a cover plate positioned over the segment supporting base having grooves therein larger than the grooves of the base member, which grooves converge to a common single groove such that wire segments entering the grooves are discharged from the single groove.
