The Hydraulic Press consists of two main parts: the main engine and the control mechanism. The main unit of the hydraulic press includes the body, main cylinder, ejector cylinder, and filling device. The power mechanism consists of an oil tank, a high-pressure pump, a low-pressure control system, an electric motor, and various pressure valves and directional valves. Under the control of electrical devices, the power mechanism converts, regulates, and delivers energy through pumps, oil cylinders, and various hydraulic valves, completing the cycle of various process actions.

Performance characteristics of Servo Hydraulic Press:

1. The body adopts a traditional bow shaped structure, similar to traditional mechanical punching machines, with a simple and compact structure, small footprint, and easy operation.

2. The main cylinder is a piston type oil cylinder with a fast cylinder inside, which can achieve high-speed downward movement and slow pressure action. Improve production efficiency.

3. The oil cylinder is of the upper cylinder type, and when the stamping slider works, it presses from top to bottom, with the lower mold stationary and the upper mold pressing.

4. The upper part of the fuselage is equipped with precision positioning devices, mechanical dead limits, and servo adjustment devices.

5. The precision positioning device is driven by a servo motor. The positioning accuracy is 0.01mm.

6. The electrical system adopts PLC+servo system+touch screen+proportional drive, combined with proportional hydraulic system, to issue instructions according to process requirements and complete the process cycle action of the machine.

7. Friendly human-machine interface, capable of accessing 200 sets of parameter programs at will.

8. The position is determined by an electronic ruler, and the travel position can be set arbitrarily. High precision positioning adopts mechanical dead limit, with a theoretical positioning accuracy of ± 0.01mm and an actual positioning accuracy of 0.01-0.02mm.

9. The pressure is detected by a pressure sensor, and the machine pressure can be set arbitrarily.

10. Mobile workbench automatic feeding.

1. Ultimate control accuracy

Position accuracy: The repeated positioning accuracy is ± 0.01mm (about 1/10 of a human hair), far exceeding the traditional machine's ± 0.1mm.

Pressure accuracy: Pressure fluctuation ± 0.5%~1%, traditional machines about ± 2%.

Speed control: Full stroke stepless speed regulation, which can accurately achieve "fast downward - slow mode closing - pressure holding - fast return".

Closed loop control: pressure/displacement/speed triple full loop, real-time compensation for oil temperature and material differences, consistency improvement of over 30%.

2. Super energy-efficient (saving 30%~70% electricity)

On demand oil supply: The servo motor only rotates during operation, stops or operates at extremely low speeds during standby/pressure maintenance, with no overflow loss.

Extremely low heat generation: The system's heat generation is only 10% to 30% of traditional machines, and most of them can eliminate the need for a cooling system.

Half the oil consumption: The oil tank is smaller, the oil change cycle is longer, and the hydraulic oil consumption is about 50% of that of traditional machines.

3. Efficient and flexible production

Faster beat: The idle stroke speed is high, the processing cycle is shortened by 15%~50%, and the beat can reach 10~15 times/minute.

Process programmable: supports programming of multiple pressure/velocity curves, can store hundreds of processes, and can be switched with just one click.

Flexible adaptation: easily meet complex processes such as precision stamping, pressing, powder forming, straightening, etc.

4. Low noise, low heat generation, more environmentally friendly

Lower noise: working noise is 70-80dB, traditional machines are 80-100dB; almost silent during standby/pressure maintenance.

Small temperature rise: stable oil temperature, extended seal and hydraulic oil life, longer maintenance cycle.

High cleanliness: reduces oil leakage and pollution, suitable for clean workshops such as electronics and medical.

5. Intelligence and ease of use

Digital monitoring: touch screen operation, real-time display of pressure displacement curve, online judgment of product qualification.

Data traceability: Processing data storage and export for easy quality control and traceability.

Remote and Automation: Supports remote control, networked diagnostics, and easy access to automated production lines.

6. Maintenance and lifespan

Low failure rate: The wear of mechanical and hydraulic components is reduced, resulting in a decrease of over 30% in failure rate.

Low maintenance cost: The frequency of cooling, oil change, and seal replacement has been significantly reduced, resulting in a comprehensive maintenance cost reduction of 50% to 70%.
