Abstract
PURPOSE: To improve economy and efficiency, by forming a cotter hole by forging and, at the same time, by simply perfoming chamfers on the margin of the cotter hole with a tapered face or a rounded surface.
CONSTITUTION: A heated pin making blank material 2 is placed on a mold B. In the first process, a rough hole 4 whose depth is about a half or a little deeper than a half of the body of the material, is installed from the top with a roughing chisel 3 having a tapered face of a rounded surface at the end, and then, after the material 2 is rotated for 180° on the mold B, another rough hole 4 having a chamfered part 6 formed at the margin with the tapered face or the rounded surface is formed from the opposite side with the roughing chisel 3. In the second process, the body of the crude material 2 is put in a circular sectional die A and pressed so that swelled part formed at the worked part is reformed. Then, the crude material 2 is brought below a finishing disel 7 and the inner surface of two rough holes 4 is finished by inserting the finising disel 7 into the holes 4. In the fourth process, the body of the blank material 2 is put in the above-mentioned sectional die A and the body is reformed with pressure.
