Pressure maintaining device for liquid die forging of bearing ring

Abstract

The utility model relates to metal forming processing technical field, and disclose a pressure -maintaining device based on bearing ring liquid state die forging, including box body, still include: fixedly connected in the inside mounting plate of box body, the inside left side mounting of mounting plate has the motor, through motor drive bidirectional screw rod rotation, utilize its screw thread drive characteristic, the accurate clamping of clamping piece's clamping block is connected in the clamping groove of mould outer wall, this structure design has realized the flexible clamping adaptation of different model mould, only need through motor control bidirectional screw rod's rotation angle, can quick adjustment two clamping piece's interval, make it closely matches mould both sides, completes steady clamping, this device has reduced the adjustment time and manpower cost when replacing mould greatly, need not complex reforming process, has improved production efficiency significantly, satisfies the diversification production demand, has strengthened the versatility and production flexibility of equipment.
