FESTO cylinder is a pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy through pneumatic transmission. Generally, FESTO cylinder is used for printing (tension control), semiconductor (spot welder, chip grinding), automatic control, robot, etc. The cylinder, end cap, piston, piston rod and seal are composed. The inner diameter of the FESTO cylinder cylinder represents the output force of the cylinder. The piston should make a smooth reciprocating sliding in the cylinder, and the surface roughness of the inner surface of the cylinder should reach Ra0.8um. For steel tube cylinders, the inner surface should also be plated with hard chrome to reduce frictional resistance and wear and prevent rust. In addition to the use of high carbon steel tubes, the cylinder material is also made of high-strength aluminum alloy and brass. Small cylinders are made of stainless steel. Cylinders with magnetic switches or cylinders used in corrosive environments should be made of stainless steel, aluminum alloy or brass. The FESTO cylinder cylinder piston adopts a combined sealing ring to realize two-way sealing, and the piston and the piston rod are linked by pressure riveting without using a nut. The FESTO cylinder end cover is provided with an intake and exhaust port, and some also have a buffer mechanism in the end cover. A seal ring and a dust seal are provided on the rod side end cover to prevent air leakage from the piston rod and prevent external dust from entering the cylinder. A guide sleeve is arranged on the rod side end cover to improve the guiding precision of the cylinder, to bear a small amount of lateral load on the piston rod, to reduce the amount of downward bending when the piston rod is extended, and to prolong the service life of the cylinder. Guide sleeves typically use sintered oil-containing alloys, forward-lead copper castings. End caps used to be malleable cast iron. Nowadays, in order to reduce weight and prevent rust, aluminum alloy die-casting is often used, and micro-cylinders are made of brass. The FESTO cylinder piston is a stressed part in the cylinder. In order to prevent the left and right chambers of the piston from suffocating each other, a piston sealing ring is provided. The wear ring on the piston improves the guiding of the cylinder, reduces the wear of the piston seal and reduces the frictional resistance. The wear ring length is made of polyurethane, polytetrafluoroethylene, cloth synthetic resin and the like. The width of the piston is determined by the size of the seal and the length of the necessary sliding portion. The sliding part is too short to cause early wear and seizure. The piston is made of aluminum alloy and cast iron, and the piston of the small cylinder is made of brass. The FESTO cylinder piston rod is the most important part of the cylinder. High carbon steel is usually used, the surface is hard chrome plated, or stainless steel is used to prevent corrosion and improve the wear resistance of the seal. FESTO cylinder seals: The seal of the part at the point of rotation or reciprocation is called a dynamic seal, and the seal of the part of the stationary part is called a static seal. 1 Single-acting cylinder: only one end has a piston rod, which can generate air pressure from the side of the piston. The air pressure pushes the piston to generate thrust and returns by spring or self-weight. 2 double-acting cylinder: alternately supply air from both sides of the piston, outputting force in one or two directions. 3 Diaphragm cylinder: replace the piston with a diaphragm, output the force in only one direction, and reset with a spring. Its sealing performance is good, but the stroke is short. 4 Impact cylinder: This is a new type of component. It converts the pressure energy of the compressed gas into the kinetic energy of the high-speed (10-20 m/s) movement of the piston. The impact cylinder adds a middle cover with a spout and a drain. The middle cover and the piston divide the cylinder into three chambers: a gas storage chamber, a head chamber and a tail chamber. It is widely used in a variety of operations such as blanking, punching, crushing and forming. The cylinder that reciprocates is called the swinging cylinder, and the inner chamber is divided into two by the vane, and the two chambers are alternately supplied with air, and the output shaft is oscillated, and the swing angle is less than 280°. In addition, there are rotary cylinders, gas-liquid damping cylinders and stepping cylinders. FESTO cylinder cylinder and end cover connection methods are mainly the following: integral type, riveted type, threaded type, flange type, tie rod type. When the cylinder is working, it is necessary to lubricate the piston by the oil mist in the compressed air. There are also a small number of lubrication-free cylinders. Hangzhou Hanxin Technology Co., Ltd. supplies the festo cylinder. The FESTO cylinder determines the thrust and tension on the piston rod based on the amount of force required to operate. Therefore, when selecting the cylinder, the output force of the cylinder should be slightly margined. If the cylinder diameter is small, the output force is not enough, and the cylinder can not work normally; but the cylinder diameter is too large, which not only makes the equipment cumbersome, high cost, but also increases the air consumption, resulting in waste of energy. When designing the fixture, force-increasing mechanisms should be used as much as possible to reduce the size of the cylinder. F: cylinder theoretical output force (kgf) F': output force (kgf) at 85% efficiency--(F'=F&TImes; 85%) D: cylinder bore (mm) P: working pressure (kgf/cm2) Example: What is the theoretical output force of a cylinder with a diameter of 340 mm and a working pressure of 3 kgf/cm2? What is the bud output? Connect P and D to find the points on F and F', get: F=2800kgf; F′=2300kgf Select the cylinder bore diameter during engineering design, according to the pressure of the use and the theoretical thrust or tension, from the experience table Found in 1-1. Example: A cylinder has a working pressure of 5kgf/cm2, and its thrust is 132kgf when the cylinder is pushed out (the cylinder efficiency is 85%). Q: How large is the cylinder bore? â—From the thrust of the cylinder 132kgf and the efficiency of the cylinder 85%, the theoretical thrust of the cylinder can be calculated as F=F'/85%=155(kgf) â—Is the selected cylinder diameter determined by the theoretical thrust of the pressure of 5kgf/cm2 and the cylinder? The cylinder of 63 can meet the requirements of use.
