Hydraulic cylinder can cooperate with various transmission mechanisms to realize simple or complex mechanical movement. At present, the application range of hydraulic cylinder is very wide, mainly in construction machinery, mining machinery, followed by metal cutting machine tools, forging machine tools, injection molding machines, in ships, aircraft, agricultural machinery, metallurgical equipment and other automation equipment and devices are also widely used.           

In practical application, people pay attention to it Design of hydraulic station The stability, strength and local stress, motion characteristics, buffer theory and service life of oil cylinder are discussed. As the main part of hydraulic press, its main function is to convert the liquid pressure energy into mechanical work. After the high-pressure liquid enters the cylinder, it acts on the piston (plunger) and transmits the force to the workpiece through the movable crossbeam, resulting in plastic deformation of the workpiece.           

In order to meet these different requirements, the Hydraulic station In the process of designing and manufacturing hydraulic cylinder, not only the process is complex, but also the requirements of material, surface quality and machining precision are very high. Therefore, it is very prudent to consider many factors in structural design. For example, in the practical application, due to the unreasonable design of the structure size, the flange height is too small or the flange outer diameter is too large, so that the local stress is too high, which is easy to cause cylinder fracture.           

In design Hydraulic system If the design of the structure from the cylinder wall to the flange is not reasonable, it may cause great stress concentration. In this way, cracks may appear soon after use. After crack propagation, the whole flange will break and fall off. In order to avoid this kind of situation, we can optimize the design of the transition line at the flange, and select the shape that can reduce the stress concentration factor.           

If the structural design of the part from the bottom to the wall of the hydraulic cylinder is not good, it is easy to cause the problem of cylinder bottom fracture. Therefore, it is very important to design the hydraulic cylinder correctly. A lot of work is needed to carry out hydraulic cylinder design and quality assurance.
