Abstract

PURPOSE: To hold the rotating work between inner and outer rolls, and to form the thin sheet without causing wrinkle and tear in spite of unemployment of the mandrel, by press holding the work near the inner roll against the press force of the outer roll.
CONSTITUTION: At first, the disk type blank 2a is caught between the pressure core metal 12 and the headstock 14, and the apparatus is put on. Then, according to the program of the computer 49, the inner roll 20 contacts against the formation start point 2b of the blank 2a, and the outer roll 41 contacts from outside. The clearance δ between two rolls 20, 41, is held at the specified value, and also, the backup roll 30 is moved in the direction of arrow 51 while being thrusted against the inside of the blank 2a; hereby, the blank 2a is formed while the thickness is reduced to the specified value.
