With the development of the industry, the Hydraulic Press application range is more and more wide,Hydraulic forming technology in automobile, aerospace and pipeline and other industries has been used, mainly suitable for along the axis component change of circle, rectangle or single section hollow structures, such as automobile exhaust system of different pipe fittings; Non-circular cross-section hollow framework, such as engine bracket, dashboard and complex pipe fittings and so on.

First, working with no. 32, no. 46 is recommended for the anti-wear hydraulic oil, used oil temperature in the range of 15 to 60 degrees Celsius. Second working oil changing once every year, the first change the time should not exceed three months;The oil is allowed to join after strict filtering tank. Another the calibration check once every six months pressure gauge; In the nominal pressure maximum allowable concentrated load eccentricity under 500 t 40 mm. Too much eccentric easily caused injury or other adverse phenomenon. Last, the machine is stopped for a long time, the added parts surface should be scrubbed clean and coated with anti-rust oil. These can increase the life of the hydraulic press.
