Servo Press Upgrades - Servo presses create a new high-end product for the hydraulic press industry - more energy efficient, faster and easier to maintain. Compared to traditional hydraulic presses, the new servo hydraulic presses are faster, double the energy efficiency, and require significantly less maintenance than traditional hydraulic presses. Xintaiming servo hydraulic press is an energy-saving and high-efficiency hydraulic press that uses a servo motor to drive the main transmission oil pump, reduces the control valve circuit, and controls the slider of the hydraulic press. Good, low maintenance cost, excellent controllability and stability, are favored and recognized by more and more enterprises.

Servo hydraulic press, or simply servo hydraulic press, has set a new standard for the hydraulic press industry. Short cycle times, high precision, low energy consumption and low maintenance requirements make this product competitive in the market – not only outperforming conventional hydraulic presses but, in many cases, servomechanical presses.

Servo-driven hydraulic presses combine high performance with low operating costs. First of all, the use of servo motors to replace the control valves of the hydraulic system enables the speed, position and pressure of the hydraulic press to be completely controlled electrically. This design reduces the number of separate moving parts used, reduces fuel consumption, reduces the maximum pressure of the hydraulic system to 250 bar, and eliminates the effects of oil temperature changes. This product is more usable and repeatable, while significantly reducing maintenance requirements, resulting in an efficient workflow.

In different applications, servo motor solutions can reduce energy consumption by 40% to 70%. Heat losses from pressure valves are avoided, and some servomotors can be used as generators during braking. The hydraulic pad cylinders of the press are also operated by a servo motor, which can be used as a generator. Braking energy is transferred via a dynamic storage system to the electric motor and central DC converter for acceleration and shaping. Because the energy is stored inside the press, there is no need to draw power from the grid during peak load conditions, which greatly reduces grid connection charges. At the same time, the remaining stored energy can also be re-entered into the grid.

The entire stamping process is monitored by a closed-loop system that continuously controls the movement of the slides, quickly corrects deviations, and ensures speed and position height. Most importantly, the system ensures parallelism of the slide to the press table, a unique integrated feature that helps improve forming accuracy and reduce die wear.
