Main performance characteristics of hydraulic bending machine: 1. The hydraulic bending machine is welded by steel plates, and the welding parts are stressed by vibration. The machine has high strength and good rigidity, and the frame can be stable and not deformed for a long time. 2. The piston of the main cylinder of the hydraulic bending machine adopts aerospace technology-surface nickel-phosphorus treatment, and its hardness can reach above HRC60. The guide sleeve that moves relative to the piston adopts a zinc-based wear-resistant alloy with its own lubricity, which can make the cylinder In good working condition for a long time. 3. It adopts torsion axis synchronization and mechanical stop, which is reliable, economical and high precision. 4. The distance of the back gauge and the stroke of the upper slider are electrically adjusted, manual fine-tuning, digital display. 5. The upper die is equipped with a winding compensation mechanism.
