An apparatus for cutting off of the twisted ends of a bonding wire is wound around a collar

摘要

The device described comprises two shearing blades with cutting edges mounted on a shear frame, at least one of which is movable relative to the other. A bending surface, arranged on one side of the movable shearing blade (57) near the cutting edge, bends the twisted end remaining on the coil after the binding wire is cut toward the coil. A clamping saw (66, 67) for gripping the cut twisted end is arranged near the cutting edge on the side of each shearing blade (56, 57) opposite the bending surface. The clamping jaw (67) provided at the shearing blade (57) with the bending surface is elastically pretensioned and is movable relative to the cutting edge of said shearing blade.
