Abstract: PURPOSE: A base material integrated tab plate manufacturing method and an apparatus thereof are provided to facilitate more convenient maintenance and post-management by the simplification of the apparatus and to increase productivity. CONSTITUTION: A base material integrated tab plate manufacturing method is composed of the following steps. Burring work on an inner through hole of a beading unit and re-striking and burring work on the outside of the beading unit are performed(S6) after a second drawing step(S5). The final shape of a tap nut is formed through the process of piercing forming a through hole for the installation of a place on the periphery of the tap nut, notching, bending and blanking. The screw is processed on the inner circumference of the beading unit passing through a second tap nut shape completion stage(S8).
