Function and structure of the thin cylinder is what?

Design of thin cylinder take up less space, with light structure, beautiful appearance, can bear large transverse load, no installation accessories can be installed directly on all kinds of fixture and special equipment. : the role of thin cylinder pressure of compressed air can be converted into mechanical energy, driving mechanism as a straight line reciprocating movement, swinging and rotary motion. Thin cylinder structure: by the cylinder, end cover, piston, piston rod and seal. Part 1) The inner diameter of the cylinder and cylinder size represents the size of the cylinder and output force. Piston within the cylinder to do reciprocating sliding, smooth surface roughness should reach the inner surface of cylinder Ra0. 8um。 Inside the steel cylinder, should also be hard chrome plated surface, to reduce the friction and wear resistance, and can prevent rust. Cylinder material in addition to the use of high carbon steel tube, or use of high strength aluminum alloy and brass. Small cylinder using stainless steel pipe. With magnetic cylinder or switch used in the corrosion environment of cylinder, cylinder should use material such as stainless steel, aluminum alloy or brass. 2) End cover on the end cover is equipped with inlet and exhaust his, oil is still end cover with buffering mechanism. Rod side on the end cover is equipped with the seal and shield, in order to prevent air leakage and outward from the piston rod to prevent external dust entering in cylinder. Rod side on the end cover is equipped with guide sleeve, in order to improve the orientation precision of cylinder, piston rod under the small amount of lateral load, decrease when the piston rod out under bending capacity, extending the service life of the cylinder. Guide sleeve is typically used before sintering oil bearing alloy, copper casting. End cover malleable iron is commonly used in the past, now to reduce weight and anti-rust, often use aluminum alloy die-casting, miniature cylinder with brass material. 3) Detroit pistons in the thin cylinder pressure parts. Each other so that both cavity to prevent piston gas, is equipped with piston sealing ring. Wear ring on the piston cylinder can be improved guidance, reduce the piston sealing ring wear, reduce frictional resistance. Long wear ring using polyurethane, ptfe, fabric material such as synthetic resin. By the width of the piston ring size and length of sliding parts necessary to decide. Sliding part is too short, easy cause early wear and jammed. The piston material commonly used aluminum alloy and cast iron, small cylinder piston made of brass. 4) The piston rod is the stress of the key parts in the thin cylinder piston rod. Often use high carbon steel, hard chrome plating on the surface, or the use of stainless steel, to prevent corrosion, and raise the wearability of seal ring. 5) Seal rotating or reciprocating motion component seal is called dynamic seal, still a part of the seal is called static seal. The application field of thin cylinder: printing ( Tension control) , semiconductor ( Spot welding machine, grinding chip) , automation control, robot and so on.
