Hydraulic profile bending machine
The aircraft structure for the symmetric three-roll,the upper roll which do up and down movements is in the center of the two down rollers,landing exercise by the hydraulic cylinder piston in the role of the hydraulic fluid obtained for hydraulic transmission;the two down rolls for the next rotation. Through the reducer output under the roller gear with the gear mesh for the provision of rolling plate torque.The disadvantage is the plate with the other end of the pre-bending device.
The machine is the most advanced profile molding equipment at home and aboard.It is used in oil,chemical,producing ship,water and electricity,metal structure,machinery and so on.
