る。Function In this lead wire cutting device for electronic components, as the pair of cutting blades move close to each other, the guide edge provided on the cutting edge surface of the cutting blade engages with the other blade body. The cutting edge surfaces facing each other are accurately aligned so that each cutting edge embeds into the side of the lead wire, and the cutting edge of the cutting blade is accurately thrust while allowing the excess portion of the lead wire to protrude from the cutting edge into the chamfered recess on the side. At the same time, the lead wire is cut, and the cutting blade is pressed against the inner surface of the cut end forming groove to crush it, so that the tip of the lead wire can be sharpened at an acute angle and cut into a desired shape of an approximately inverted conical shape. At the same time, the excess axis of the lead wire, including the excess that protrudes laterally from the cutting edge, can be discharged as chips from the chamfered recess located on the side of the cut end forming groove, without shifting the axis of the lead wire. The tip side can be cut smoothly and accurately into an acute angle, and the tip side of the lead wire, which is sharply pointed in the shape of an inverted cone, can be inserted into the insertion hole of the printed circuit board, so it is easy to insert into the printed circuit board. It becomes possible to smoothly attach electronic components without the tip getting caught when cutting, bending, etc. in the clinch mechanism.
