Abstract
The machine for the cold heading of bolts has three dies (246, 248, 250) mounted side by side in a common die block (50). The centre die (246) performs the first upsetting operation and the outer dies (248, 250) finish form the bolt head. The blanks (252, 258) are supported in punches (24, 26) aligned with the centre die and alternately with the one of the outer dies. Alternate axial and lateral movements of the die block rough form one blank and finish form another blank, which is then ejected and replaced by a new blank which is rough forged whilst the second blank is finish formed.
