What are the outstanding advantages of hydraulic press?
A hydraulic press is a machine that uses liquid as a working medium and is made according to Pascal's principle to transfer energy to achieve various processes. Hydraulic machine is generally composed of the machine (host), power system and hydraulic control system of three parts. Hydraulic machine classification has valve hydraulic machine, liquid hydraulic machine, engineering hydraulic machine.
The outstanding advantages of hydraulic press are:
1, the work is stable, the impact and vibration is small, the noise is small, which is of great benefit to the health of workers, the plant foundation, the surrounding environment and the equipment itself.
2. Voltage regulation and speed regulation are convenient. The hydraulic press uses the pressure of the working liquid to transfer energy, can adjust the pressure and limit the pressure by adjusting various pressure control valves, and can reliably prevent overload, which is beneficial to protect the mold and equipment. The adjustable range of the moving speed of the movable beam is very large, which can adapt to the different requirements of the working speed of different technological processes.
3, easy to get a larger total pressure and a larger working space. This is the outstanding advantage of hydraulic press. Based on the principle of hydraulic transmission, the actuator structure of the hydraulic press is simple, and the power equipment can be arranged separately, and can work with multiple cylinders. The working area of the liquid pressure and the piston (or plunger) can be changed in a large range. And because the hydraulic press is a static pressure equipment, without a large foundation, so you can do a lot of tonnage. At present, among all kinds of forming equipment, hydraulic presses are mostly used for those requiring larger pressing tonnage, and almost all hydraulic presses are above 100,000 kN.
4, easy to get a larger working stroke, easy to press large-size workpieces, and can produce a rated large pressure on any position of the stroke, can be a long time pressure. This characteristic of the hydraulic press is very necessary for some processing techniques, such as deep drawing, extrusion, plastic molding, superhard material synthesis, etc.
