Servo Pressing Machine Driven by an AC servo motor, it outputs force through a high-precision ball screw. It has a built-in high-precision pressure sensor and encoder, which can measure parameters such as speed, pressure, and position. Using professionally developed control software, it controls the pressing pressure, stop position, pressing speed, and pressure holding time throughout the entire process, achieving intelligent control and management of the entire process and establishing an automated pressing workstation.
With the successful development of high-power servo motors and the rapid promotion and application of frequency conversion technology, servo presses with adjustable slider motion curves have emerged, greatly improving the working performance and process practicality of the press, and the pressure is developing towards flexibility and intelligence. After years of development, servo technology has been widely used in the stamping field. In the fields of product forming presses and automotive parts presses, servo technology has borne fruit through the efforts of many technicians. It has been increasingly recognized and accepted by more and more manufacturers in the metal stamping industry, the automotive parts motor bearing pressing industry, and the refractory industry.
Assembly operations are commonly used processes in mechanical engineering. Especially in the automotive and automotive parts industry, the assembly of parts such as bearings and bushings is achieved through pressure assembly.
As a new technology, servo presses have advantages that traditional hydraulic presses do not possess. In the automotive manufacturing process, such as the pressing of cylinder head valve seat rings and guides, cylinder block waterway covers, transmission bearings, and wheel hub bearings. It is gradually replacing traditional hydraulic presses through equipment upgrades, effectively improving the level of automotive manufacturing technology.
As far as bearing pressing is concerned, bearings are moving parts, and the pressing effect directly affects the performance and life of the vehicle or product/equipment. The higher the tolerance requirements for the boring of bearing parts, the more important it is to effectively monitor the pressing force and displacement during the bearing pressing process. Traditional hydraulic or pneumatic pressing equipment cannot effectively control the pressing pressure and displacement during the pressing process, resulting in bearings being jammed and unable to rotate or rotating inflexibly due to instantaneous overload of the pressing force. The driving power source of the servo press is controlled by an intelligent, flexible, and sensitive servo motor, combined with a pressure sensor, and the pressure, displacement, and speed can all be adjusted, which can effectively solve the overload caused by speed and pressure. At the same time, by monitoring the pressing force and displacement online, the pressing effect can be effectively judged, the pressing parameters can be saved, and the traceability of the pressed parts in the main plant can be realized. Processes with similar precision requirements are all suitable for completion by a servo press during the pressing process.
The above are some knowledge points about servo Pressing Machine I hope everyone can carefully learn and understand the relevant knowledge and choose products that suit their needs.

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
