The embodiment adopts the following steps: the pressing edge of the lower straightening press head 22 has a saw-toothed structure and has a plurality of V-shaped lower pressing grooves 221 arranged in an array.
2) The data cable 4 clamped to the cable clamping jig 11 is tinned through a tinning process (namely, the data cable 4 clamped to the cable clamping jig 11 is tinned after the tinning process in advance), and then is conveyed forwards through the jig conveying assembly to enter a middle cutting process (because the assembly line type processing operation is adopted, the jig conveying assembly can convey the cable clamping jig 11 forwards to pass through each process); the outer skin of the end of the data cable 4 has been stripped, a plurality of core wires 41 are exposed, the wire body of the data cable 4 is clamped to the wire body clamping portion 111, the plurality of core wires 41 are respectively clamped to a plurality of core wire clamping positions arranged in the core wire clamping portion 112, so that the ends of the plurality of core wires 41 extend out to the front side of the cable clamping jig 11, the ends of the plurality of core wires 41 have also been stripped, metal core wires 42 are exposed, and each metal core wire 42 is twisted into a strand by a plurality of metal wire cores (metal wires).

It should be noted here that since each metal core wire is composed of a plurality of metal wire cores (metal wires) twisted into a strand, if the cutting is directly performed by a planar blade, the metal wires are crushed and spread when being interfered by the cutting force of the blade. That is, the end of the metal core wire cut by the flat cutting blade is generally flat and loose, and the subsequent assembly process cannot be guaranteed. Moreover, since the exposed portion of each metal core wire is stained with tin material, if a planar cutting edge is used, the tin plating (staining) effect is also affected, for example, the tin plating structure is damaged by cutting. In addition, the serrated cutting edges have the advantage that each wire can be combed once to avoid the adhesion of tin materials, besides the function of preventing the metal core wires from being loose after being cut. Structural design is carried out through the cutting edge to upper and lower cutter, adopts the form that the grooving adds the inclined plane, because the existence on V groove and cambered surface structure inclined plane guarantees the strand shape of metal heart yearn, leads to loosely when avoiding just cutting off.
