Head stretch forming hydraulic press stretch forming press 315 tons four-column hydraulic press 315t metal stretch forming hydraulic press
The head forming hydraulic press has two kinds of single action and double action. Single action means only stamping cylinder, no blank pressing cylinder, and only small and medium-sized factories are in use. Large factories use double action, that is, there is a pressing cylinder, a stamping cylinder. The transmission medium of the hydraulic press is water, which is cheap, moves quickly, and is not stable. The sealing requirements are not as high as those of the hydraulic press, the efficiency is lower than that of the hydraulic press, and the guidance requirements are not strict. The transmission medium of the hydraulic press is oil. A change of oil is more expensive than water. The transmission is stable. The requirements for sealing are high, the requirements for guidance are high, and the requirements for oil are high. If the oil is not filtered or the oil circuit is switched or closed quickly, the system will be affected. Certain actions produce impact and make the press move unstable. Therefore, it is necessary to filter the oil frequently, change the oil on time, and thoroughly clean the oil tank when changing the oil.
