What is the structure of FESTO cylinder?

FESTO cylinderAccording to the internal structural analysis, the main components in the cylinder are: cylinder barrel, end cap, piston, piston rod, and seal. The inner diameter of the cylinder represents the actual output force of the cylinder. Under normal circumstances, the piston should slide smoothly inside the cylinder, and the surface roughness of the cylinder should reach ra0.8 μ m.

At the same time as the FESTO cylinder, the end cap is also an important component. Usually, there are corresponding intake and exhaust ports on the end cover, and some of them also have buffer mechanisms inside the end cover. The end cover on the rod side is equipped with a sealing ring and a dust ring to prevent leakage of the piston rod and prevent external dust from entering the cylinder. The end cover on the rod side is equipped with a guide sleeve, which can improve the guiding accuracy and bear some lateral loads on the piston rod, reduce the downward bending of the piston rod when it extends, and extend the service life of the cylinder.

In FESTO cylinders, the guide sleeve components are typically made of sintered oil containing alloys and copper castings tilted forward. At the same time, in order to reduce weight and achieve rust prevention effect, the end cap is mainly made of aluminum alloy die-casting, and the micro cylinder is made of brass material.

FESTO cylinder, in addition, the piston is an important pressure bearing component in the entire equipment. Meanwhile, in order to prevent mutual air leakage between the left and right chambers of the piston, a piston sealing ring is provided. The wear-resistant ring on the piston can improve the guiding performance of the cylinder, reduce the wear of the piston sealing ring, and lower the frictional resistance. Wear resistant rings are usually made of polyurethane, polytetrafluoroethylene, and laminated synthetic resin materials. The width of the piston is determined by the size of the sealing ring and the length of the required sliding components. The sliding part is too short, which can easily cause early wear and jamming.

Another important component of FESTO cylinder is the piston rod, which is an important load-bearing component in the cylinder. The piston rod is generally made of high carbon steel or stainless steel coated with hard chromium on the surface to prevent corrosion and improve the wear resistance of the sealing ring.

Do you know how FESTO cylinders are lubricated and reset? During the operation of a cylinder, it mainly refers to a container in an internal combustion engine or external combustion engine that allows the piston to reside inside and reciprocate up and down during operation. During the manufacturing process, it is mainly composed of a cylinder barrel, end cap, piston, piston rod, and sealing components.

FESTO cylinders are divided into two types: those that perform reciprocating linear motion and those that perform reciprocating oscillation; When working, it is necessary to lubricate the piston with oil mist in compressed air.

The pneumatic actuator in FESTO cylinder effectively converts the pressure energy of compressed gas into mechanical energy. There are two types of cylinders: those that perform reciprocating linear motion and those that perform reciprocating oscillation. Cylinders that perform reciprocating linear motion can be divided into four types: single acting, double acting, diaphragm type, and impact cylinder.

The single acting cylinder in FESTO has a piston rod at only one end during operation. During operation, gas is supplied from one side of the piston to generate air pressure, which pushes the piston to produce thrust and extend, returning by spring or self weight.

Double acting cylinder, alternately supplying air from both sides of the piston, outputting force in one or two directions. Replace the piston with a diaphragm, output force in only one direction, and reset with a spring. It is sealed, but has a short travel.

The impact cylinder is a new type of component to some extent, which effectively converts the pressure energy of compressed gas into the kinetic energy of high-speed piston movement during operation, in order to do work. The general term for cylinders without piston rods. There are two main types: magnetic standard cylinders and cable cylinders.

Cylinder is a relatively small device, but it has a wide range of uses. Only in the mechanical field, many of its shadows can be found. It can play different roles in different situations according to different needs. Let's take a look at its use in machinery.

1. FESTO cylinder as a compression tool for tissue

Firstly, the cylinder is a highly ambitious stamping equipment with outstanding performance. Its presentation quickly replaced the bulky stamping equipment of the past, and the production of many products cannot do without its assistance and support, which also saved a lot of costs. For example, it can be used in the production of car parts, including the pressing of guide sleeve bushings and the pressing of lower ring rubber bushings. When used as a pressing device, it is necessary to confirm the pressing method (up and down or left and right) in advance, as well as the pressing load, and then select the appropriate cylinder diameter and stroke according to the requirements, and confirm the correct device method based on the device orientation.

2. FESTO cylinder as guiding organization

From the perspective of its homework content alone, it is actually a very simple and repetitive task. However, if a suitable guide rod is installed on its piston rod and the electrical control of the cooperative equipment is used, the guide rod can be actively guided. In this way, it can be used in the valve plate assembly process of car shock absorbers. In the straight direction, there is a groove for stacking valve plates below, and the guiding cylinder is above it. The pushing valve plate is organized in the horizontal direction. Then, the active transportation of the stacking slot with the valve plate was carried out in cooperation, achieving the intention of assembling the active valve plate. As a guiding function, because it is not subject to load, small cylinder diameters can be selected according to demand, and a fixed device method can be used. Because the guiding needs to be aligned, we can install a floating joint between the piston rod and the guiding rod.
