1 Claim. 1
This invention relates to cutters, and more particularly to cutters for cutting conductors without deforming the cut ends thereof.
In the manufacture of conductors of a type wherein solid conductors are brazed together and the maximum cross-sectional dimensions of the solid conductors are critical, it is necessary that the brazed joints of the conductors be within the critical limit. Furthermore, in order to provide proper end surfaces for brazing the ends of the conductors together, the ends of the conductors are cut off to provide square ends prior to the brazing operation. In the past there have been no cutters which will cut the ends of the conductors Without deforming the ends of the conductors to a substantial degree, and Without forming rough surfaces on the ends of the conductors. Such deformedends of the conductors cause considerable trouble because the maximum dimensional limits might be exceeded.
An object of the invention is to provide new and improved cutters.
A further object of the invention is to provide new and improved cutters for cutting the ends of the conductors without deforming the ends thereof.
An apparatus illustratin certain features of the invention may include a holder for holding a conductor designed to have one end thereof cut off, and a blade mounted pivotally with respect to the holder having an arcuate cutting edge thereon, said arcuatecutting edge serving to slice the conductor as the cutting edge is pivoted with respect to the holder so that the conductor is sliced off without deforming the end thereof.
A complete understanding of the invention may be obtained from the following detailed description of a cutter forming a specific embodiment thereof, when read in conjunction with the appended drawings, in which:
Fig. 1 is a perspective view of a cutter forming one embodiment of the invention;
Fig. 2 is an enlarged, fragmentary elevation of a portion of the cutter with the elements of the cutter in position to start a cutting operation on a conductor;
Fig. 3 is a view similar to Fig. 2, but with the cutter in a different position in the cutting operation;
Fig. 4 is a view similar to views 2 and 3 with the cutter in a still different position in the cutting operation;
Fig. 5 is a fragmentary section taken along line 5-5 of Fig. 2, and
Fig. 6 is a perspective view of a cutter forming an alternative embodiment of the invention.
Referring now in detail to the drawings, a bracket I0 secured to a brazer I2 has a conductor-holding arm I4 doubled back therefrom and extending non-parallelly with respect thereto. The arm is provided with a bore I6 designed to fit closely around a conductor I8, which is to have a roughly sheared end portion I9 thereof cut therefrom. The bore I6 permits the conductor to be inserted therethrough with the end portion of the conductor extending beyond the face of the arm I4. A pin 20 secures pivotally to the arm I4 a slicer 22 having a handle portion 24. The slicer 22 is provided with an acute, hollow ground cutting edge 26 formed by bevelling the slicer 22 and hollow grinding the edge. The cutting edge 26 includes a straight portion 28 and an arcuate portion 30 which is arcuate about a point between the longitudinal axis of the pin 20 and the cutting edge 26.
When the slicer 22 is pivoted in a clockwise direction, the straight portion 28 of the cutting edge 26 first engages the conductor I8 and is moved in a partial slicing movement across the conductor. As the cut progresses the arcuate portion 30 of the cutting edge 26 increases the slicing action of the slicer 22 and the entire conductor is severed by slicing as distinguished from being sheared. The acuteness of the cutting edge 26 increases gradually as the'cut progresses so that the slicing action is maintained and no portion of the conductor is broken. The cutting edge 30, as it is pivoted to slice the conductor I8 in two, has a large component of movement in a slicing direction as it is pivoted, and this slicing or pulling of the cutting edge 26 across the conductor I8 increases progressively as the cut progresses so that there is more and more slicing action as distinguished from shearing action as the cut progresses. Since the severin action is a slicing action, the end of the conductor held in the bore I6 in the arm I4 of the bracket I 0 is not deformed and is not roughened. Hence, a very good splice may be made between it and another end similarly formed on a second conductor identical therewith.
A plier-type cutter forming an alternative embodiment of the invention shown in Fig. 6 includes a holder lever III] having a conductorholding arm II4 provided with a bore H6. A slicer I22 identical with the pivotally attached to the holder lever IIU (Fig. 6). The plier-type cutter cuts a conductor I I8 with the same slicing action as the cutter shown slicer 22 (Fig. 1) is axis of the conductor.
3 in Figs. 1 to 5, inclusive, with the conductorholding arm H4 (Fig. 6) performing the same functions as the arm 14 (Fig. 1).
The above-described apparatus serves to out conductors in a manner in which the newly formed ends of the conductor are square, smooth and undeformed. The ends of the conductor formed by the cutters are planar, are very smooth and are perpendicular to the longitudinal Hence, excellent brazed joints between two such ends may be obtained therefrom.
What is claimed is:
A cutter, which comprises an arm for holding the end of a conductor to be severed, and a cuting element having an acute cutting edge thereon and movable across the face of the arm in contact therewith in a direction such that the cutting edge slices the conductor, the cutting ele-' ment being so constructed and arranged that when it is moved in a cutting direction across the face of the arm the slicing action of the cutting edge thereon progressively increases and the cut- 4 ting edge being so constructed and arranged that the acuteness of the portions thereof in contact with the conductor progressively increase during a cutting operation.
