4000T CNC hydraulic forming equipment

The high-pressure forming equipment is specially designed and developed to meet the special needs of the forming process of lightweight and high-strength structural parts of automobiles, and its development trend is large-scale, flexible and intelligent; and the pressure control and hydraulic servo control of the ultra-high pressure device are the core of the development of the forming equipment, and its performance characteristics are as follows:
Each equipment is equipped with two pressurized cylinders with a maximum pressure of 400MPa, which can process complex workpieces with large deformation and high yield strength;
The pressure control accuracy of the booster cylinder is ± 0.5Mpa, which can fully meet the requirements of the pipe forming pressure accuracy;
The resolution of the oil cylinder displacement sensor is 0.001mm, and the accuracy of the side cylinder during actual control is 0.1mm, which can fully meet the requirements of the filling accuracy when the workpiece is formed;
The oil cylinder adopts one-to-one servo control, the fastest speed can reach 110 mm/s, while the traditional servo valve has a small diameter, and the speed is much faster than that of servo valve control at the same cost.
