 hydraulic press


   Special hydraulic press for compound well cover Is a liquid as the working medium, used to transfer energy to achieve various processes of the machine. Hydraulic press is not only used for forging forming, but also for straightening, pressing, packing, pressing block and pressing plate. Hydraulic press includes hydraulic press and hydraulic press. The water-based liquid as the working medium is called the hydraulic press, and the one with oil as the working medium is called the hydraulic press. The specification of hydraulic press is generally expressed by nominal working force (KN) or nominal tonnage (ton). Forging hydraulic press is mostly hydraulic press with high tonnage. When the pressure is higher than 35 MPa, it is often used for large-scale forging equipment. The working pressure of hydraulic press for other purposes is 6 ~ 25 MPa. The tonnage of hydraulic press is lower than that of hydraulic press.

   Working medium

The working medium used in hydraulic press is not only to transmit pressure, but also to ensure that the working parts of the machine work sensitively, reliably, with long service life and less leakage. The basic requirements for working medium of hydraulic press are: ① suitable fluidity and low compressibility to improve transmission efficiency; ② anti rust; ③ good lubrication performance; ④ easy sealing; ⑤ stable performance and long-term operation without deterioration. Water is used as the working medium of hydraulic press, and then a small amount of emulsified oil is added into the water to increase the lubricity and reduce the corrosion. In the late 19th century, hydraulic press with mineral oil as working medium appeared. The oil has good lubricity, corrosion resistance and moderate viscosity, which is beneficial to improve the performance of hydraulic press. In the second half of the 20th century, a new type of water-based emulsion appeared, which is "water in oil" instead of the original "oil in water". The outer phase of water in oil emulsion is oil, its lubricity and corrosion resistance are close to oil, and the oil content is very small, so it is not easy to burn. However, the high price of water-based emulsion limits its popularization.

   Product advantages

For the hollow variable cross-section structural parts, the traditional manufacturing process is to form two half pieces first, and then weld them into a whole, while hydroforming can form the hollow structural parts with changes along the cross-section of the components at one time. Compared with stamping welding process, hydroforming technology and process have the following main advantages:
1. Reduce weight and save materials. For typical parts such as engine bracket and radiator bracket, the weight of hydroforming parts is 20% - 40% less than that of stamping parts, and the weight of hollow stepped shaft parts can be reduced by 40% - 50%.
2. Reduce the number of parts and molds and reduce the cost of molds. Hydroforming parts usually only need one set of dies, while most stamping parts need more than one set of dies. The number of engine bracket parts reduced from 6 to 1, and the number of radiator bracket parts decreased from 17 to 10.
3. Reduce the amount of subsequent machining and welding. Taking the radiator bracket as an example, the heat dissipation area increased by 43%, the number of solder joints decreased from 174 to 20, the process decreased from 13 to 6, and the productivity increased by 66%.
4. Improve the strength and stiffness, especially the fatigue strength. For example, the stiffness of the hydroforming radiator bracket can be increased by 39% in the vertical direction and 50% in the horizontal direction.
5. Reduce production cost. According to the statistical analysis of applied hydroforming parts, the production cost of hydroforming parts is reduced by 15% ~ 20% and the die cost is reduced by 20% ~ 30%.

   Maintenance and maintenance

1. No.32 and No.46 anti-wear hydraulic oil is recommended for working oil, and the oil temperature is within 15-60 ℃.
2. The oil is allowed to be added into the oil tank after strict filtration.
3. The working oil should be changed once a year, and the time for one change should not exceed three months;
4. The sliding block shall be filled with lubricating oil frequently, and the surface of column surface shall be kept clean, and the oil shall be sprayed before each operation.
5. Under the nominal pressure of 500t, the concentrated load is large and the allowable eccentricity is 40mm. The column is easy to be damaged due to excessive eccentricity.
6. Calibrate and check the pressure gauge every half a year;
7. If the machine is out of service for a long time, the surface of each adding part should be cleaned and coated with antirust oil.
