[0041] After the primary forging of the bearing ring, the bearing ring is transferred to the heat treatment process, and is placed on the base plate 9 in turn by the multiple stacked charging frames 8 filled with the bearing ring. By the external industrial computer control, the electric sliding table 3 and the electric sliding rail are started to move the entire clamping assembly 10 above the charging frame 8, and then the lifting cylinder 12 is started to lower the clamping height of the upper and lower clamping claws 17 and 18, so that the clamping plates 24 of the upper and lower clamping claws 17 and 18 are opposite to the outer edge 26 of the charging frame 8 for subsequent clamping.
