Abstract (en)

The present invention relates to a tube yoke manufacturing apparatus in which a tube yoke having a spline in a tube part through a forging process can be quickly manufactured and the shape of the spline may be prevented from being distorted. The tube yoke manufacturing apparatus according to the present invention comprises a plurality of tube yoke forming dies configured to form a tube yoke comprising a tube part and a yoke part by inserting a material into a dice and pressing the material by means of a punch, wherein the apparatus further comprises a spline forging die provided with a forming pin having a spline part formed in an outer circumferential surface thereof and thereby making a spline formed inside the tube part as being inserted into the tube part.
