Strictly speaking, Foshan hydraulic presses are not a new type of technological equipment. Their principle is that the speed curves of the nodes in the multi-rod system are not constant during movement, and can be optimized as needed to achieve the effect of slowly approaching the workpiece and quickly returning.
In stamping production, improving production efficiency is a common goal of forging and pressing equipment users and manufacturers. A simple method is to increase the operating speed of the press. However, due to the limitations of the material mechanical properties of the stamped workpiece, there are also limitations on increasing the forming speed. The use of multi-link drive technology Foshan hydraulic press ， can achieve the purpose of improving productivity without increasing the working stroke speed, according to the requirements of the material performance curve.
Foshan hydraulic press The method used is to optimize the working stroke speed and increase the idle stroke speed, thereby achieving the purpose of improving the overall production efficiency of the machine. At the same time, because the speed of the press slide in the working stroke section is reduced, the speed of the upper and lower molds at the moment of mold closing is also greatly reduced, which improves Foshan hydraulic press the impact phenomenon during operation, greatly extending the mold life, and effectively reducing the impact noise during stamping.
Multi-link structure Foshan hydraulic press The main features include:
1) Compared with ordinary Foshan hydraulic press Compared with ordinary, the design of the drive part of the press driven by the multi-link mechanism is different, and other parts of the press are still standard, so the cost can be greatly reduced.
2) Compared with the press driven by a crank slider mechanism with the same technical parameters, the crank radius and crank torque are smaller, making the press structure compact, the overall size smaller, and the weight lighter, which is of great significance for manufacturing large presses.
3) Under the same nominal pressure, the Foshan hydraulic press can withstand greater loads in a longer working area, and does not need to increase the tonnage of the press to meet the special requirements of the stretching process.
4) The Foshan hydraulic press has the characteristics of slow advance and fast return. Speeding up only increases the running speed of the slide in the non-working area, so while meeting the requirements of drawing speed, the number of strokes of the press slide can be increased as much as possible, thereby improving stamping production efficiency.
5) The slide of the multi-link drive press can contact the sheet metal at a slower speed, reducing the possibility of material tearing, improving the quality of stamped parts, reducing the impact load on the mold, and extending the life of the mold.
6) Because the main drive of the Foshan hydraulic press adopts a rod system, the slide runs smoothly, and the main machine noise is greatly reduced compared with ordinary crank connecting rod presses, improving the working environment of operators on the press production line.
7) The stress state of the main parts of the Foshan hydraulic press is superior to that of ordinary crank connecting rod presses. In the drawing area, the load on the members of the main drive system is almost linear, making the torque load lower than that of the crank connecting rod press. The load on each drive element of the Foshan hydraulic press is relatively low, so its acceleration and braking inertia are lower, thus greatly saving energy.

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
