Cylinder Cylinder Type: A pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy in pneumatic transmission. There are two types of cylinders: those that perform reciprocating linear motion and those that perform reciprocating swing. Cylinders for reciprocating linear motion can be divided into single-acting, double-acting, diaphragm and impact cylinders.
① The single-acting cylinder only has a piston rod at one end. Air is supplied from one side of the piston to accumulate energy to generate air pressure. The air pressure pushes the piston to generate thrust and extends, and returns by a spring or its own weight.
② The double-acting cylinder supplies air alternately from both sides of the piston and outputs force in one or two directions.
③The diaphragm cylinder uses a diaphragm instead of a piston, only outputs force in one direction, and is returned by a spring. It has good sealing performance but short stroke.
④Impact cylinder This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of high-speed (~m/s) movement of the piston to perform work. The impact cylinder adds a center cover with a spout and a drain port. The middle cover and piston divide the cylinder into three chambers: air storage chamber, head chamber and tail chamber. It is widely used in various operations such as blanking, punching, crushing and forming. The cylinder that swings back and forth is called a swing cylinder. The inner cavity is divided into two by a blade, and air is supplied to the two cavities alternately. The output shaft swings with a swing angle of less than 1. In addition, there are rotary cylinders, gas-liquid damping cylinders and stepping cylinders.
The function of the cylinder converts the pressure energy of compressed air into mechanical energy, and the driving mechanism performs linear reciprocating motion, swinging and rotating motion.
Cylinder classification: cylinders with linear motion and reciprocating motion, swing cylinders with swing motion, air claws, etc.
The structure of the cylinder barrel. The inner diameter of the cylinder barrel represents the output force of the cylinder. The piston should slide smoothly back and forth in the cylinder barrel. The surface roughness of the inner surface of the cylinder barrel should be as rough as that of the steel tube cylinder barrel. The inner surface should also be plated with hard chromium to reduce frictional resistance and wear and prevent corrosion. In addition to using high-carbon steel pipes, the cylinder barrel material is also made of high-strength aluminum alloy and brass. Some small cylinders use stainless steel tubes. For cylinders with magnetic switches or cylinders used in corrosion-resistant environments, the cylinder barrel should be made of stainless steel, aluminum alloy or brass. The cylinder piston uses a combined sealing ring to achieve two-way sealing, and the piston and piston rod are connected by riveting without nuts.
Cylinder end cover The end cover is provided with intake and exhaust ports, and some also have a buffer mechanism in the end cover. The rod side end cover is equipped with a sealing ring and a dust ring to prevent air leakage from the piston rod and external dust from mixing into the cylinder. There is a guide sleeve on the rod side end cover to improve the guiding accuracy of the cylinder, bear a small amount of lateral load on the piston rod, reduce the amount of downward bending of the piston rod when it extends, and extend the service life of the cylinder. Guide sleeves are usually made of sintered oil-containing alloy, forward-inclined copper castings. In the past, malleable iron was commonly used for end caps. Nowadays, in order to reduce weight and prevent rust, aluminum alloy die-casting is often used, and brass materials are sometimes used for micro cylinders.
Cylinder Piston The piston is the pressure-bearing part in the cylinder. In order to prevent the left and right chambers of the piston from channeling air, a piston sealing ring is provided. The wear-resistant ring on the piston can improve the guidance of the cylinder, reduce the wear of the piston seal ring, and reduce friction resistance. The wear-resistant ring length uses materials such as polyurethane, polytetrafluoroethylene, cloth-filled synthetic resin, etc. The width of the piston is determined by the size of the sealing ring and the necessary length of the sliding section. The sliding part is too short, which can easily cause early wear and jamming. The materials of piston are commonly aluminum alloy and cast iron, and the piston of small cylinder is made of brass.
