143 METHOD OF MANUFACTURING DOOR HINGE FOR AUTOMOBILE EP11759186.7 2011-03-08 EP2551036A1 2013-01-30 YOKOYAMA Michihiro

The present invention provides a method for manufacturing a high-strength motor vehicle door hinge from a steel plate blank at low cost. The method includes a cold heading step of forming a cylindrical bulging portion at one end of the blank in the width direction, a shaft hole forming step of forming a shaft hole in the cylindrical bulging portion, and a shaft hole finishing step. In the shaft hole forming step, a shaft hole is formed using a first punch having a top end with a shape of a cone and first die having an inner wall with a gap volume relative to the outer circumferential surface of the cylindrical bulging portion of the blank. The size of the gap volume is set so that when the first punch punches the cylindrical bulging portion of the blank, a hole portion formed from an end at which machining of the first punch starts to a predetermined length position does not produce a punched slug and the cylindrical bulging portion bulges outward and a hole portion from the predetermined length position to the end at which the machining of the first punch ends produces a punched slug to be ejected. In the shaft hole finishing step, the shaft hole is finished from the end at which the machining of the first punch ends using a second die having a shape substantially the same as the shape of the first die and a second punch having a top end with a shape of a truncated cone or a cone and the largest diameter that is larger than that of the first punch.
