[0014] The cable wire ends after tin dipping are shaped by the first shaping die 2 and the second shaping die 3, and the excess wire ends are cut off by the cutting knife 8, so that the shapes and lengths of the wire ends of the same batch of cable wires are kept consistent, and the problem of rework and trimming is eliminated. The cable wire end tin dipping process is applied to the cable wire end tin dipping process, so that the consistency of the quality of the cable wire ends can be effectively improved.

[0015] The cutting knife 8 in the embodiment is preferably in sliding connection with the rack 1, and the top end of the cutting knife 8 is provided with a base 9 protruding to one side of the second shaping die 3, the driving mechanism 4 is connected with the base 9 and drives the base 9 to move, the second shaping die 3 is in sliding connection with the cutting knife 8 and elastically abuts between the base 9 through the spring 10, and when the second shaping die 3 is separated from the first shaping die 2, the spring 10 drives the plug-in connector 6 of the second shaping die 3 to completely extrude the slot 7 out of the cutting knife 8.

[0016] The spring connection between the base 9 and the second shaping die 3 can make the second shaping die 3 first close to the first shaping die 2 to limit the position and shape of the cable wire end, and then the cutting knife 8 cuts off the excess wire end, so that the position of the cable wire is limited during the cutting process of the cutting knife 8, the wire end cutting surface is flat, and the wire end cutting surface is flat.

[0017] In the embodiment, the cutting knife 8 and the rack 1 can be in sliding connection through a conventional sliding rail and sliding groove connection structure, and the second shaping die 3 and the rack 1 can also be in sliding connection through a sliding rail and sliding groove connection structure.
