The crimping machine includes a crimper opposed to an anvil for crimping a stripped wire end to a terminal; a vertical rotation shaft axially secured on a base frame; a lower rotating base disc axially engaged with a lower end of the rotation shaft; an upper rotating base disc and a shank each axially slidably engaged with an upper end of the rotation shaft by way of a spline; and a flange formed at an upper end of the shank and engaged with a hook-shaped portion formed at a lower end of the pressing ram. The lower and upper discs have respectively a plurality of fitting channels radially extending from the rotation shaft. Each channel of the upper disc is detachably mounted with the crimper, and each channel of the lower disc is detachably mounted with the anvil. An adjusting dial for adjusting crimp height of the crimper is respectively provided in an outer surface of the shank. In place of the adjusting dial, there may be provided an adjusting disc adjusting crimp height of the crimper and having a plurality of positioning bosses with different vertical thicknesses.

Multiple-terminal crimping machine

A wire stripping apparatus includes: a first cam and an external gear which are fixedly secured to a rotary shaft; a slider which is movable horizontally with respect to the first cam; a base stand secured to the slider; a pair of cutter holders which are provided on the base stand in such a manner that they are vertically movable; an internal gear which is rotatably provided through intermediate gears in the external gear; a second cam which is secured to the internal gear, and has a cam groove which is symmetrical in a 180.degree. rotation mode; and a pair of swing levers which have followers, and are engaged with the cutter holders in such a manner that the latter are horizontally slidable. Thee second cam comprises: first, second, third cam surfaces which are gradually larger in height. More specifically, in the second cam, a pair of the first cam surfaces, a pair of the second cam surfaces, and a pair of the third cam surfaces are arranged symmetrical in a 180.degree. rotation mode. With respect to an abutment protrusion provided on said slide, positioning cams in the form of plural stages are provided on a select shaft. In a wire stripping method, the cutters operate to cut the cover near the end of the wire, and then the cutters are retracted to strip the wire halfway. Thereafter, the cutters is slightly moved forwardly, and then the conductor is cut.
