Servo Press The slider's movement is achieved by driving an eccentric gear with a servo motor. Through sophisticated electrical control, the servo press can arbitrarily program the slider's stroke, speed, and pressure, even reaching the rated tonnage of the press at low speeds. The working principle of a servo press differs from that of a traditional press. Based on the summary of the characteristics and working mechanism of the servo press, a technical scheme and structural design method for the servo press are proposed. Based on the energy accumulation principle in the constant torque system, the design calculation formulas for servo motor parameters, total inertia moment, dynamic acceleration time, and motor shaft braking torque are derived. The results show that the designed servo press has the advantages of simple structure, reliable operation, and low cost.
Friction presses have advantages such as simple structure, reliable performance, low cost, and easy maintenance. To date, with a history of nearly 200 years, they remain widely used. Although friction presses have low control accuracy and high energy consumption, they are characterized by low cost and simple structure. Moreover, they still have a large market in China. Friction presses are ordinary forging equipment that suits China's national conditions. However, because they increase the complexity of the press structure and operation, thus increasing the manufacturing and maintenance costs of the press, they have not been widely used in China.
A screw press is a press that achieves forging by moving the slider up and down through the rotation of a screw. Screw presses not only have the functions of a forging hammer but also the characteristics of a mechanical press. Therefore, they are widely used in various forging processes, especially in forging processes that save materials and energy. Screw presses have a simple structure, strong versatility, no dead points in the slider, simple adjustment and maintenance, and convenient mold design. They are suitable for various processes such as calibration, finishing, refining, and calibration. In the 1950s, the rapid development of the aviation industry and the power industry promoted the rapid development of screw presses.
The clutch screw press is a new type of screw press launched in the late 1970s. This clutch screw press surpasses the traditional press's flywheel rotation movement and the structural form of the spiral flywheel combination. The clutch screw press is a new type of screw press that breaks through traditional transmission methods and combines the advantages of forging hammers, mechanical presses, and hydraulic presses.
Clutch screw Press is a new type of screw press. During operation, the unbalanced inertia and moment of inertia of its moving parts will cause vibration of the machine base, and the vibration caused during impact work is very strong. The clutch screw press is an energy-saving new type of general-purpose electromechanical hydraulic forging equipment. It has the advantages of high output energy, high impact frequency, computer control, long mold life, programmable pre-selection and setting of working parameters, and fault display. It is widely used in forging, die forging, extrusion, and finishing processes.

What are the characteristics of a hydraulic press?
CNC hydraulic oil pumps generally use internal gear pumps, while traditional hydraulic presses generally use axial piston pumps. At the same flow rate and pressure, the noise of an internal gear pump is 5 dB to 10 dB lower than that of an axial piston pump. The motor of a CNC hydraulic press runs at rated speed during pressing and return, and its noise emission is 5 dB to 10 dB lower than that of a traditional hydraulic press. When the slider rapidly descends and is stationary, the servo motor speed is 0, so the CNC hydraulic press has essentially no noise emission.

Application scope and system selection of small hydraulic presses
Suitable applications for small hydraulic presses include: 1. Punching various silicone and plastic buttons for mobile phones or remote controls, and cutting plastic products; 2. Cutting various protective films for mobile phones, digital cameras, and laptop LCD screens, as well as precision cutting and halving of various pressure-sensitive adhesives and trademarks; 3. Embossing, forming, etc., of various PV, PE, PC and other thin-film switches and panels; 4. Pressing and forming various flexible circuit lines for laptop keyboards, etc. Small hydraulic presses use original Taiwanese or Japanese parts for the hydraulic power system, resulting in fewer malfunctions, high efficiency, low noise, low horsepower requirements, easy maintenance, and convenient adjustment of output, speed, and stroke.

Technology Daily (Reporter Shi Junbin, Correspondent Jiao Yue) Recently, a 19,500-ton free forging hydraulic press and a 300-ton/750-ton-meter full hydraulic forging manipulator, independently developed by China Heavy Industry Corporation, successfully completed their first hot load test run in Jiangyin, Jiangsu Province. This marks the completion of the world's largest tonnage free forging hydraulic press and the world's largest clamping force/clamping torque full hydraulic forging manipulator currently in operation, achieving a globally advanced level of overall equipment installation. The 19,500-ton free forging hydraulic press adopts a three-beam, four-column, three-cylinder, top-drive, press-insert, full pre-stressed frame structure. Both the upper and lower beams use pre-stressed composite beams. The maximum forging capacity can reach 4
