Abstract

The invention discloses a manufacturing method of high-strength and corrosion-resistant alloy steel nails. The method includes the following steps that (1) alloy steel nail raw materials are insertedbetween a nail punching grinding tool and a punching machine power head, the steel nails are manufactured through punching of a punch, and the steel nails punched down enter a nail discharging plate to push steel nails ahead for extruding advancing; (2) the steel nails enter a nail bearing wheel to rotate and are overlapped with a nail extruding rail at the bottom of the nail bearing wheel; (3) the steel nails enter a soft plastic belt packaging belt from the nail extruding rail, and nesting of the steel nails is performed; and (4) when the number of the steel nails reaches a certain numericalvalue, the soft plastic belt is cut off by a cutting machine, and coil nails are formed after being coiled. The method has the characteristics of high efficiency and quickness, and the produced steelnails have the characteristics of high strength and corrosion resistance.
