The hydraulic loops is designed with zero load, combined with extremely low frequency oil pump motor, effectively reduced nosie, and increased motor effciency and service duration The driving and hydraulic motors are featured with high torque. Whenever the circle roller and semi-circle formation are processed, the outer diameter and bent angles can be adjusted at random with precise formation dimensions reached. It is coordinated with the precise electrical control system and each part is designed with both manual and automatic operation. The body frame is designed with the composite assembly with robust and endurable spare parts. It is convenient to change molds and the processing capability is available for squeezing-bending work pieces, variable metal pipes and rectangle pipes. It is featured with plane circle roller operation with streamlined designs but convenient operation suitable for mass production. Application:squeezing –bending work pieces ,variable metal pipes and rectangle pipe Range of out diameter:10mm-76mm Range of thick:2mm Range of bending:0o-360o Body:L:1700mm W:920mm H:1160mm Total weight:1100KG
