Referring to fig. 1 and 2, a string tension traction string making process includes the steps of:
s1: the manipulator clamps the press connection pipe to be placed in the corresponding first extrusion tool 10, and then clamps the copper nose to be placed in the second extrusion tool 20; in step S1, the extrusion tooling is in a loose state, and after the extrusion tooling is put into the compression pipe, the extrusion tooling is in a locking state, and the compression pipe is clamped. The first extrusion tooling 10 and the second extrusion tooling 20 are respectively divided into two parts, one part is fixed, the other part is connected with a driving element, the driving element is in communication connection with a chip of the manipulator, and the driving element drives the movable part to move after the wire harness reaches a proper position, so that the accessory is clamped and positioned.
