| description | The invention provides a nut part manufacturing method which is characterized by comprising the following steps: material selection: selecting low-carbon steel with the carbon content of 0.09%-0.15% as a profile, straightly twisting and straightening the profile, feeding the straightly twisted and straightened profile into a material cutting device, and cutting off the profile with the same volume and size; drawing closed curves, engraving the closed curves on the profile by using laser equipment, blanking, punching along the closed contour curves by using a punching die, and punching the profile into a plurality of blanks, wherein the minimum distance between two adjacent closed curves is 0.5-0.7 cm; the blank is subjected to surface shaping, the blank is subjected to upsetting cutting to form a combined body of a circular truncated cone and a cylinder, the diameter of the circular truncated cone is larger than that of the cylinder, the diameter difference between the circular truncated cone and the cylinder |
