For wires with different diameters, different working modes are selected, so that the product precision is effectively improved, and breakage in the transportation and use processes caused by excessive reduction of the structural strength of the wires is avoided.
Specifically, the processor judges that the working mode selected by the continuous cutting sleeve is a high-temperature pre-cutting mode under the high fracture trend diameter level, and determines the heating temperature according to a first dimension difference value between a first diameter parameter and the diameter of the preformed wire rod;
Wherein the high fracture trend diameter level is such that the preformed wire diameter is less than the first diameter parameter and the heating temperature is inversely related to the first dimensional difference.
