Process for manufacturing universal joint

A method of manufacturing a universal joint member comprising:

• blanking a blank out of sheet metal material to form an integrated sheet metal blank having a hub member portion, lug member portions projecting on opposite ends of the hub member portion, and fork member portions projecting from one side edge of the hub member portion at right angles to the direction in which the lug member portions project;
• extruding projections on one face of the blank from the lug portions while simultaneously forming bolt hole cavities in the opposite face of the blank aligned with the projections;
• bending each root portion of the fork member portions to offset the flat fork member portions from the plane of the hub member portion on the same side of said hub member portion;
• forming the hub member portion into a cylindrical shape with the projections on the inner side projecting toward each other;
• and
• bending the hub member portion, lug member portions and flat fork member portions to form the final configuration of the universal joint member with the lug member and the projections facing each other in closely spaced relationship, and said flat fork member portions extending parallel to each other.
