Manufacturing process of adjusting nut

Abstract

The invention discloses a manufacturing process of an adjusting nut. The steel billet raw materials are manufactured into wire rod materials, surface treatment is performed on the wire rod materials by using phosphate, spheroidizing annealing, phosphating and fine-drawing and sizing treatment are respectively performed on the wire rod materials after roughing, and finally, the molding working procedure of the adjusting nut is carried out in a cold-heading molding machine; the molding working procedure of the adjusting nut comprises the following steps: material fracturing; material shaping and upsetting, upsetting an inner chamfer at the upper end; material turning, shaping and upsetting a positioning hole at the upper end and an inner chamfer at the lower end; material translating, upsetting a counterbore at the front end and a positioning hole at the rear end; material turning, upsetting a counterbore at the other end; material translating, upsetting a plane in the middle by using the PKO male die technology; discharging the residual scrap iron at a middle hole out and manufacturing a through hole product; and performing tapping to an inner hole of a blank of the adjusting nut. The invention is molded at one time by adopting a cold heading machine, thereby improving the production efficiency and the product quality of the adjusting nut, saving the raw material and reducing the manufacturing cost.
