Abstract
The invention discloses a manufacturing process of a screw. The process comprises the following steps of (1) preparation of wires: using a stainless steel wire; (2) annealing; (3) acid pickling: putting the annealed wires in a hydrochloric acid solution with concentration of 20-25% to soak, cleaning by clean water, putting into a phosphate solution with concentration of 5-8% to soak, cleaning by clean water, and applying a proper amount of lubricating agent; (4) shaping: putting the acid pickled wires in a wire drawing machine, drawing to the required diameter, and performing cold upsetting for shaping; (5) thread grinding: fixing a thread plate, enabling a movable thread plate to drive the product to move, and forming the required threads by extrusion; (6) heat treatment. The manufacturing process has the advantages that the process is simple, a crystallizing structure is adjusted by annealing, the hardness is decreased, the processing property of the wire is improved, an oxidation film on the surface of the wire is removed by acid pickling, and the hardness of the screw is improved by heat treatment.
