Abstract

The invention discloses a wire softening process of an enameled wire. The wire softening process comprises the following steps of (1) preparing a softening device; (2) preparing before softening, in which a wire subjected to releasing is placed in an annular passage, a wire surface detergent is introduced into the annular passage via a valve, and the two ends of the annular passage are sealed by annular sealing covers; and (3) softening, in which a motor is started to lead a rotary shaft to rotate, the rotational speed is controlled within 200-300 r/min, rotation is kept for 10-20 minutes and stopped, high-steam is introduced through the valve during rotation, and the wire is taken out. The wire softening process has the advantages that the wire is placed in the annular passage and rotated with the rotary shaft, the surface stress of the wire is removed by using a centrifugal force, meanwhile, the wire is immersed in the wire surface detergent in the annular passage, surface oil stain is removed as well as the stress can be removed, a condition is created for a subsequent painting process, energy consumption is low, and no pollution is generated.
