2 to 4, the manufacturing method of the T-shaped hinge according to the preferred embodiment of the present invention is a molding process (S100), bending process (S110), bonding process (S120), drilling process (S130) and coupling A process S150 may be included, and the surface treatment process S140 may be further performed.

(1) forming process

The molding process (S100) is a process of press molding into a shape required for manufacturing the hinge from a metal material.

The molding process (S100) is to cut the metal material into a square plate shape of a predetermined size to form a fixed side plate 100 and a rotating side plate 200, respectively, the fixed side plate 100 and the rotating side plate 200 This is achieved by forming coupling holes 110 and 210 at mutually opposite positions.

The molding process (S100) is preferably performed using a press.

As the metal material of the molding process (S100), any one of iron, stainless steel, aluminum, and silver may be used, and preferably, iron having excellent strength is used.

(2) bending process

The bending process (S110) is a process of bending and curing a metal material formed into a predetermined shape to deform the shape necessary for the hinge.

The bending process (S110) forms a fixed side pipe part 120 by curing one side end of the fixed side plate 100 to the inside, and spaces apart from the end of the fixed side plate 100 at predetermined intervals to the outside. It is vertically bent to form the fixed side reinforcement portion 130, and one side end of the rotating side plate 200 is cured inward to form the rotating side pipe portion 220, and the end of the rotating side plate 200 and predetermined The parts spaced at intervals are formed by vertically bending the ends outward to form the rotation side reinforcement part 230.

(3) bonding process

The bonding process S120 is a process of bonding a portion of the metal material deformed into a hinge shape.

The bonding process (S120) is bonded to the surface of the stationary side plate 100 by welding or riveting the rear surface between the stationary side pipe part 120 and the stationary side reinforcement part 130 (WR part). And a back surface between the pivoting pipe part 220 and the pivoting reinforcement part 230 by welding or riveting the surface of the pivoting plate 200 by welding or riveting.

(4) drilling process
