The accumulator of the hydraulic pump of the plate shearing machine drives the unit of the accumulator, so it can also be used as a group, as well as the system power, power loss, cavitation, temperature rise and wear. In the case of quantity, the accumulator is used for storage. The former is used to improve liquid hemiplegia, while the latter is used to regulate the limited pressure of the system. Select universal hydraulic oil. It is surprising to consider system pressures and equipment. If the above conditions are met, the scissors cannot be selected properly, and then they can defeat the sputum, viscosity and the service life of the hydraulic press.

The shear is equipped with safety protection equipment to ensure the safety of equipment and human body. The pattern is relatively large, and the power will also be lost. The shear is indirectly driven by a pump. The pump supplies the hydraulic cylinder. Low pressure liquid, simple in form and sharp in operation, is widely used and easy to trim, and is used for casual forging and die forging, but it is difficult to automate materials due to large disturbance. In the hydraulic system of the hydraulic press, the hydraulic oil is bad. Surprisingly, no matter whether it is suitable or not, it does not need to have the robustness of the hydraulic system movement, the reliability and sensitivity of the hydraulic system.

The disadvantages of plate shears are difficult to make, expensive, and sensitive to tensile and notch stresses. The performance of the high efficiency grinding spindle unit of the shear largely determines the limit of the effective grinding process of the coiler. Therefore, in order to finish the effective grinding of the shears, it is generally required that the drive and transport speed of the grinding wheel zigzag machine be high. The large surface speed of the magnetic bearing can reach 200m/s, and the shear may become the choice of ultra high speed spindle bearings in the future.

The high speed of the shearing machine spindle requires that the spindle winding machine has sufficient rigidity, high rotation accuracy, good thermal stability, reliability, low power consumption and long life. In order to meet these requirements, the manufacture and dynamic balance of the main shaft, the support of the main shaft (bearing), the lubrication and cooling of the main shaft coiling system and the rigidity of the system winder are important. Therefore, the bearing of the spindle shear can be a ceramic rolling bearing, an magnetic bearing, an aerostatic bearing or a hydrodynamic bearing. Ceramic ball bearings have the advantages of light weight, small coefficient of thermal expansion, high hardness, high temperature resistance, high temperature scale stability, corrosion resistance, high life and high elastic modulus.
