Precautions when installing main cylinder of hydraulic press machine, if the operation is improper during installation, or the arrangement of some places during the installation is unreasonable, then it has a great impact on the service life of the main cylinder of the hydraulic press machine, and it will also have a greater impact on the working performance of the hydraulic press machine, which is bound to reduce the production efficiency.
Therefore, we must pay attention to the relevant operational requirements when installing main cylinder of hydraulic press machine, and the contact surface between the flange of the hydraulic cylinder and the beam should be in close contact with more than 80% of the area.
                                                                      
Due to the long-term use of some hydraulic press machines, the accuracy of the contact surface is destroyed, and the local contact can not be good and good, so that the supporting reaction force of the beam at the local contact increases sharply, and the speed of damage will be accelerated. The stiffness of the beam is not enough or the arrangement of the ribs at the place where the hydraulic cylinder is installed is unreasonable, which will also lead to the uneven distribution of the reaction force on the flange contact surface, resulting in excessive working stress.
The connecting bolt of the flange of the cylinder block and the beam is often loose, if it cannot be tightened in time, it will cause the damage caused by the cylinder body channeling and impact, and the result is that the contact surface of the beam is constantly depressed, and the local contact becomes extremely bad. The coupling air purifier bolts are tightened while the hydraulic cylinder is pressurized. Some small hydraulic presses use snap rings or keys at the bottom of the cylinder to fasten the cylinder and the beam, which has a certain effect on preventing the loosening of the cylinder.
Therefore, when installing the main cylinder of the hydraulic press, we must pay attention to the problems mentioned above, which is not only for the service life of the main cylinder, but also the working performance of the hydraulic press, which must be taken seriously.
In addition, it should be noted that other working fluids in the hydraulic press machine often have a corrosive effect on the cylinder wall, which will reduce its fatigue strength. The hydraulic oil used in the hydraulic press machine should have good rust resistance, so that both should be kept at the corresponding pH, so as not to break their pH balance.
