Foshan Hydraulic Press This is a general term, including presses and hydraulic presses. It is characterized by wide application and high production efficiency. It processes metal into parts by applying strong pressure to metal blanks, causing plastic deformation and fracture.
Screw Foshan Hydraulic Press Using a screw and nut as the transmission mechanism, the screw drive converts the forward and reverse rotation of the flywheel into the up and down reciprocating motion of the slider. During operation, the motor accelerates the flywheel rotation to save energy, while the slider is pushed down by the screw nut. When the slider contacts the workpiece, the flywheel is forced to decelerate to a complete stop, and the stored rotational kinetic energy is converted into impact energy, which deforms the workpiece by impacting it through the slider. After completion, the motor reverses the flywheel, driving the slider to rise and return to its original position. Screw Foshan Hydraulic Press specifications are indicated by the nominal working force.
Crank Foshan Hydraulic Press It is a common cold stamping equipment, used as the working platform for cold stamping dies. It has a simple structure and is easy to use. Depending on the bed structure, the crank Foshan Hydraulic Press can be divided into open crank Foshan Hydraulic Press or closed crank Foshan Hydraulic Press . According to the number of drive connecting rods, it can be divided into single-point pressing or multi-point pressing; according to whether the number of sliders is one or two, it can be divided into single-acting Foshan Hydraulic Press or double-acting Foshan Hydraulic Press 。
Multi-station Foshan Hydraulic Press is an advanced stamping equipment, which is the integration of multiple Foshan Hydraulic Press . It generally consists of a line head unit, a feeding mechanism, Foshan Hydraulic Press and a line tail. The beat can reach 40 beats/min or more, which can meet the requirements of high-speed automated production. The line end unit can be divided into a dismantling unit, a magnetic tape, cleaning and oiling equipment, etc. The feeding mechanism usually includes a feeding arm; generally, presses are divided into multi-slider and single-slider, which can be selected according to different requirements. The tail end of the production line is usually composed of a conveyor belt.
The working mechanism is driven by a motor through a transmission mechanism to apply process force to the workpiece. The transmission mechanism is a speed reduction mechanism of belt drive and gear drive; the working mechanism is divided into screw mechanism, crank connecting rod mechanism and hydraulic cylinder.
Foshan Hydraulic Press It is divided into three categories: screw Foshan Hydraulic Press ，crank Foshan Hydraulic Press and hydraulic press. Crank Foshan Hydraulic Press also known as mechanical Foshan Hydraulic Press 。
Screw Foshan Hydraulic Press There is no fixed bottom dead center. For larger die-forged parts, it can be formed by multiple stamping, and can be single-stroke, continuous stamping and inching. The impact force is related to the deformation of the workpiece. When the deformation is large, the impact force is small, and when the deformation is small, the impact force is large. These aspects are similar to forging hammers. However, its impact force is enclosed by the frame, so the operation is very stable, the vibration is much smaller than the forging hammer, and a large foundation is not needed.
Foshan Hydraulic Press is equipped with a forging injector at the bottom. It can be used for die forging, blanking, drawing and other processes. In addition, screw Foshan Hydraulic Press has a simple structure and is easy to manufacture, so it is widely used.

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
