    • Disclosed therein are a coupling boss and a method for fabricating a coupling boss, that a collar part is formed through a collar drawing process using a metal plate material, and then, a body part of the coupling boss is firmly combined to a substrate plate through processes of deep drawing, tapping, cleansing, plating and iron coining in order, thereby maximizing competitive power in price, miniaturizing the coupling boss in size, and maximizing tensile strength, compression strength, and surface roughness. In this instance, a more stable material thickness can be kept by performing a collar drawing process or a curling process when a screw part of the coupling boss is formed. The processes of: forming a collar part (2) through a collar drawing process for forming a screw part (8) of the coupling boss (1) using a metal plate material; forming a body part (3) and a flange part (4) on the metal plate material, on which the collar part (2) is formed, through a deep drawing process; and tapping to form the screw part (8) on the inner peripheral portion of the collar part (2) and the processes of: forming a body part (3) and a flange part (4) by a deep drawing process using a metal plate material; forming a collar part (2) on the body part (3) by a curling process; and tapping to form a screw part (8) on the inner peripheral portion of the collar part (2) are performed selectively. After that, the formed coupling boss (1) is firmly combined to a substrate plate (5) through the processes of cleansing, plating, and iron coining.
    • 其中公开了一种联接凸台和一种用于制造联接凸台的方法,其中通过使用金属板材料的套环拉伸工艺形成凸缘部分,然后将联接凸台的主体部分牢固地组合到基板板 进行深冲,攻丝,清洗,电镀和熨烫的过程,从而最大限度地提高价格竞争力,使联轴器的尺寸小型化,并最大限度地提高拉伸强度,抗压强度和表面粗糙度。 在这种情况下,当形成联接凸台的螺纹部分时,通过执行套环拉伸过程或卷曲过程可以保持更稳定的材料厚度。 通过使用金属板材料形成联接凸台(1)的螺纹部分(8)的套环拉伸工艺来形成凸缘部分(2)的过程; 通过深拉伸工艺在其上形成有凸缘部分(2)的金属板材上形成主体部分(3)和凸缘部分(4); 并且在凸缘部分(2)的内周部分上形成螺纹部分(8),并且通过使用金属板(2)的深拉伸工艺形成主体部分(3)和凸缘部分(4) 材料; 通过卷边工艺在主体部分(3)上形成凸缘部分(2); 并且选择性地进行敲击以在轴环部件(2)的内周部分上形成螺纹部分(8)。 之后,通过清洗,电镀和铁压印的过程将形成的联接凸台(1)牢固地组合到基板(5)。
