315 ton 400 ton 500 ton three-beam four-column hydraulic press machines operating procedures:

1. Equipment action: start with both hands → press the cylinder quickly → sense the slow proximity switch → press the cylinder slowly → keep the pressure timing → time is up → the cylinder quickly returns to the upper limit proximity switch position → the action is completed. (The position of the proximity switch and pressure holding time can be adjusted freely)
2. The hydraulic power system adopts a high-pressure pump, and the hydraulic circuit is specially designed, which can reduce the power consumption during standby, so as to save energy, with stable performance, low noise, small horsepower requirements, and adjustable output, speed and stroke.
3. The machine adopts fast hydraulic cylinder with two stages of speed, fast downward and slow working. During long-term operation, the oil temperature is not easy to rise, and the pressure is stable.
4. Comprehensive safety design, two-hａnd operation, manual and automatic gears, emergency buttons and jogging of the upper and lower molds, which are convenient for mold installation and calibration; installed with photoelectric protection safety devices;
5. The machine is equipped with a pressing counter, which can record the daily pressing times.

The 315-ton 400-ton 500-ton three-beam four-column hydraulic press machines is suitable for pressing processes of various plastic materials, such as stamping, bending, flanging, drawing, forming, punching, bending, etc. of sheet metal parts. It can also be engaged in calibration, press fitting, grinding wheel forming, pressing and forming of plastic products and powder products.

1. Auto parts; body covers, brake pads, fuel tanks, chassis, axle housings, bumpers.
2. Household appliances: washing machines, rice cookers, televisions, refrigerators, air conditioners and other parts.
3. Kitchen utensils: sinks, pots, and other containers.

★★Maintenance

(1) 30# hydraulic oil is recommended for working oil. If the engine oil or turbine oil is selected, it should be determined according to the temperature: when the room temperature is lower than 20 ℃, 20# engine oil or 22# turbine oil can be used. When the room temperature is higher than 30℃, 30# can be selected. The operating oil temperature should be within the range of 15°C to 60°C.

(2) The oil should be strictly filtered before it is allowed to be added to the oil tank. The oil filling amount in the oil tank should not be lower than the oil mark, and the filling tank should also be added to the oil mark position.

(3) The working oil should be replaced every six months, and the immediate replacement time should not exceed two months. (The new grades of oil are N32, N46 ordinary hydraulic oil, and N32, N46 mechanical oil can also be used instead.

(4) The exposed parts of the column and the plunger should be sprayed with oil frequently, and it should be sprayed once before each work.

(5) Under the nominal force, the concentrated load is very large and the allowable eccentricity is 50mm. If the eccentricity is too large, it is easy to strain the column or cause other undesirable phenomena.

(6) Check and calibrate the pressure gauge every six months.

(7) When the 315-ton 400-ton 500-ton three-beam four-column hydraulic press machines is out of use for a long time, the machined surfaces should be cleaned and coated with anti-rust oil.

1. How to choose hydraulic oil for a 315-ton 400-ton 500-ton three-beam four-column hydraulic press machines?

Determine certain properties of the oil used, such as viscosity, density, vapor pressure, air solubility, bulk modulus, combustion resistance, temperature boundary, pressure boundary, lubricity, compatibility, and select or configure according to certain needs After the hydraulic oil is used, it cannot be assumed that the problems of the working medium of the hydraulic system have been fully resolved. In fact, if it is used improperly, the properties of the oil will still change. For example, it is usually thought that the viscosity of oil at a certain temperature and pressure is a certain value, and it has nothing to do with the active state. In fact, after the oil is excessively sheared, the viscosity will be significantly reduced.

2. In order to ensure the stability of the 315-ton 400-ton 500-ton three-beam four-column hydraulic press machines, under the condition of using hydraulic oil, the long-term use of hydraulic oil, oxidation, and thermal stability are the factors that determine the temperature boundary. Therefore, The hydraulic oil should be kept at a temperature lower than its initial oxidation temperature for a long time. During the process of storage, transfer and filling, the oil should be prevented from being polluted, and the oil should be sampled regularly. The storage volume of the liquid should be sufficient to facilitate the heat dissipation of the hydraulic system and maintain the sealing of the system. Once there is leakage, it may be removed immediately.
