Basic Introduction to Front Cylinder

Front oil cylinder: Sleeve type oil cylinder is a method to improve machining quality. There is a significant difference in service life between post plating polishing and post plating polishing, especially in mass production. Strictly clean the flying edges and burrs of mechanical components, especially the edges and small metal burrs at the sealing groove, and clean them strictly before assembly. The finishing process of the cylinder bore adopts rolling, which can significantly improve the fatigue strength and stress corrosion resistance of the cylinder surface. The roughness of the friction pair surface is generally controlled between Ra0.4 and 0.8. Repair method for oil cylinder wear: 1. Apply metal repair material to the scratched surface; The first layer should be thin, evenly and completely covering the scratched surface to ensure the best adhesion between the material and the metal surface. Then, apply the material to the entire repair area and press it repeatedly to ensure that the material is filled and reaches the required thickness, slightly higher than the surface of the guide rail; 2. It takes 24 hours for the material to fully achieve all its properties at 24 ℃. To save time, the temperature can be increased using a tungsten halogen lamp. For every 11 ℃ increase in temperature, the curing time is reduced by half. The optimal curing temperature is 70 ℃; 3. After the material solidifies, use a fine grinding stone or scraper to repair and level the material above the surface of the guide rail, and the construction is completed. The definition of oil cylinder in Baidu Baike: A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When using it to achieve reciprocating motion, there is no need for a deceleration device, and there is no transmission clearance, resulting in smooth motion. Therefore, it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of the piston and the pressure difference on both sides; A hydraulic cylinder is basically composed of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffering device, and an exhaust device. Buffer devices and exhaust devices depend on the specific application scenario, while other devices are essential. When the long stroke oil cylinder rotates horizontally, the piston rod deflects due to its own weight, causing the guide sleeve and piston to be biased, resulting in damage to the cylinder head seal, oil leakage, and piston sleep syndrome in the cylinder barrel. To address this, the following measures can be taken: increase the piston size, adjust the outer circle of the piston to be processed into a convex shape, so that the piston can self position, improve the stress condition, and reduce and avoid cylinder pulling; The connection between the piston and the piston rod adopts a spherical joint. Reasons and countermeasures for oil cylinder seal leakage: a. Loose pull rod nuts can cause leakage. Re tighten the pull rod nuts according to the torque requirements and test for no further leakage before continuing to use. b. Pressure exceeding the limit can also cause leakage. Replace the cylinder seal and tighten the rod nut again to reduce the pressure to the nominal pressure range of the hydraulic cylinder. c. The cylinder seal is deformed by compression, and if the O-ring is clearly visible at the cylinder seal, replace the cylinder seal.

Reference price for front oil cylinder

The cost of the front oil cylinder is determined by factors such as usage environment, technical requirements, stroke range, and operating speed. Whether synchronization is required or not varies, and the price also varies. The cost of common brands of front oil cylinders ranges from 1000/yuan to 6000/yuan.

Maintenance and related issues of the front oil cylinder

• Control principle of servo oil cylinder
  The working principle of the electro-hydraulic pulse servo oil cylinder is composed of a stepper motor, a three position four-way servo valve, a mechanical feedback device (wire support pair), and an oil bar. When the stepper motor receives a pulse signal, its output shaft rotates by 1.5 or 3 degrees, and the servo valve core drives the screw to rotate simultaneously. The valve core moves and opens the reversing oil cylinder to output pressure oil. The piston moves and drives the screw to rotate in the opposite direction, causing the valve core to return to its original position. The servo valve returns to the center position and stops outputting pressure oil. At this time, the oil cylinder moves by 0.1 or 0.2mm stroke, and the displacement and speed of the oil cylinder are determined by the given value of the electric pulse.

• How many tons can a hydraulic cylinder with a diameter of 100 and a pressure of 10mpa hold?
  The cross-sectional area of the cylinder is π * (100/2) ^ 2=3.14 * 2500=7850 square millimeters=0.00785 square meters. Pressure=pressure * cross-sectional area=Pa * 0.00785 square meters=78500 newtons. Mass=pressure/g=78500 newtons ÷ 9.8 newtons/kilogram=8010 kilograms=8.01 tons ^ 2 is square, and g is the acceleration due to gravity

• What is the working principle of the hydraulic cylinder in the shearing machine?
  Plate cutters; Guillotine shear is a machine that uses one blade to perform reciprocating linear motion relative to another blade to cut sheet metal. It is achieved by using a moving upper blade and a fixed lower blade, with a reasonable blade gap, to apply shear force to metal sheets of various thicknesses, causing the sheets to fracture and separate according to the required size. The shearing machine belongs to a type of forging machinery, mainly used in the metal processing industry. The product is widely used in industries such as aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobiles, electricity, electrical appliances, and decoration to provide the required specialized machinery and complete sets of equipment. Working principle: The shearing machine should be able to maintain stability after cutting
