The purchase requirements of hydraulic shearing machine and its high precision performance

by:WORLD     2022-08-14

The performance of the hydraulic shearing machine also has great advantages, so it has been recognized by many manufacturers. The following world press machine will introduce the purchase requirements of the hydraulic shearing machine and the performance of high precision.

Purchase requirements for hydraulic shears:

(1), good antioxidant stability. Oxidative stability refers to the ability of the oil to resist chemical reactions with oxygenates when the temperature of the oil increases. Practice has shown that for every 10 °C increase in oil temperature, the chemical reaction rate is approximately doubled. The shearing machine hydraulic oil with good oxidation resistance and stability is not easy to be oxidized and deteriorated when used for a long time, which can ensure the normal circulation of the hydraulic oil.

(2) The hydraulic oil of the shearing machine should have good anti-wear and lubricity. The purpose is to reduce mechanical friction and ensure the service life of the hydraulic system of the shearing machine.

(3), maintain proper viscosity. The specific use depends on the working pressure of the hydraulic system of the shearing machine, the working temperature and the movement speed of the actuator. High viscosity should be selected for high pressure and high temperature, and low viscosity should be selected for high-speed motion.

(4), good viscosity-temperature. Viscosity-temperature refers to the degree to which the viscosity of the oil changes with temperature, which is usually expressed by the viscosity index.

(5) Good anti-emulsification and anti-foaming properties. Emulsification resistance refers to the ability of oil to be mixed with water and become an emulsion after agitation, from which water is separated. Anti-foaming property refers to the ability of the oil to be mixed with air and stirred to form an emulsion, and the air bubbles can be separated from the oil. After mixing with water or air, the volume modulus of the oil is reduced, the compressibility is increased, the hydraulic components of the shearing machine are slow to act, and it is easy to produce shock and vibration.

The performance of hydraulic shearing machine with high shearing precision:

(1) The rear guide rail of the tool holder body of the hydraulic gate shearing machine is supported by 4 large bearings, and the front guide rail is pressed by 2 bearings with compression springs on the back, so that there is no clearance between the front and rear guide rails, and the clearance and edge The gap addition accuracy error is kept below 4 wires, so the sheared material is smoother and free of burrs

(2) The hydraulic gate shearing machine tool holder moves in a vertical straight line relative to the lower blade to ensure that the shearing sheet is less twisted and deformed and the straightness is more accurate.

(3) The hydraulic gate shearing machine is not easy to deform because the oil cylinder, the tool holder and the blade are in the same line and move perpendicular to the lower blade.

(4) The winding and iron core of the linear motor are directly exposed to the air, so the heat can be removed to the air in time, and the temperature will not rise too high even if it runs for a long time.

The above is the relevant introduction, I believe that everyone has a certain understanding of the hydraulic shearing machine.
