ATOS cylinders, also known as hydraulic cylinders, are linear motion actuators whose output force is proportional to the effective area of ​​the piston and the pressure difference across it. Their function is to convert hydraulic energy into mechanical energy. The input to a hydraulic cylinder is the flow rate and pressure of the fluid, and the output is linear motion speed and force. The piston of a hydraulic cylinder can perform linear reciprocating motion, but the output linear displacement is finite. A hydraulic cylinder is an energy conversion device that converts hydraulic energy into reciprocating linear motion mechanical energy. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, piston and piston rod, sealing device, cushioning device, and venting device. The cushioning device and venting device depend on the specific application, while the other devices are...

The working principle of an ATOS cylinder mainly involves five components. Let's first discuss its five most basic components: 1- Cylinder barrel and cylinder head, 2- Piston and piston rod, 3- Sealing device, 4- Cushioning device, 5- Venting device.

The working principle of each type of ATOS hydraulic cylinder is almost the same. Take a manual jack as an example. The jack is actually a simple hydraulic cylinder. The hydraulic oil is pushed into the cylinder through a one-way valve by the manual booster rod (hydraulic manual pump). At this time, the hydraulic oil entering the cylinder cannot be reversed because of the one-way valve, which forces the cylinder rod to move upward. Then, the hydraulic oil continues to enter the hydraulic cylinder during operation, and so on. When it is time to descend, the hydraulic valve is opened to let the hydraulic oil return to the oil tank. This is the simple working principle. Other cylinders are improved on this basis. The principle of the pneumatic cylinder is basically the same as that of the hydraulic cylinder. [1]

ATOS hydraulic cylinder processing

ATOS hydraulic cylinder trundle processing

ATOS hydraulic cylinder trundle processing is a non-cutting process. At room temperature, it uses the plastic deformation of metal to smooth the micro-unevenness of the workpiece surface, thereby changing the surface structure, mechanical properties, shape and size. Therefore, this method can achieve both finishing and strengthening at the same time, which is something that grinding cannot do. Regardless of the machining method used, fine, uneven tool marks will always remain on the surface of the part, creating a staggered peak-and-valley effect.

ATOS cylinder roller burnishing principle: It is a pressure finishing process that utilizes the cold plasticity of metal at room temperature. A roller burnishing tool applies pressure to the workpiece surface, causing the surface metal to plastically flow and fill the original residual low-lying valleys, thus reducing the surface roughness. Due to the plastic deformation of the roller-burnished surface metal, the surface structure is cold-hardened and the grains are refined, forming a dense fibrous structure and a residual stress layer, increasing hardness and strength, thereby improving the workpiece's wear resistance, corrosion resistance, and fit. Roller burnishing is a non-cutting plastic machining method.

Non-cutting machining technology is safe, convenient, and allows for precise control of accuracy. Several advantages include:

1. Improved surface roughness, with a roughness generally reaching Ra≤0.08µm.

2. Corrected roundness, with ellipticity ≤0.01mm.

3. Increases surface hardness, eliminating stress deformation; hardness increase HV≥4°.

4. Leaves a residual stress layer after machining, increasing fatigue strength by 30%.

5. Improves fit quality, reduces wear, and extends part lifespan, while simultaneously reducing machining costs.

ATOS Hydraulic Cylinder Rolling (Folded Section)

ATOS hydraulic cylinders are crucial components in engineering machinery. Traditional machining methods include: broaching the cylinder body – precision boring the cylinder body – grinding the cylinder body. The rolling method involves: broaching the cylinder body – precision boring the cylinder body – rolling the cylinder body. While the process consists of three parts, the time difference is significant: grinding a 1-meter cylinder body takes approximately 1-2 days, while rolling a 1-meter cylinder body takes approximately 10-30 minutes. Investment comparison: grinding machines or honing machines (tens of thousands to millions), rolling cutters (thousands to tens of thousands). After roller burnishing, the surface roughness of the hole decreases from Ra3.2–6.3µm before burnishing to Ra0.4–0.8µm, the surface hardness of the hole increases by approximately 30%, and the fatigue strength of the cylinder inner surface increases by 25%. Considering only the cylinder's influence, the cylinder's service life increases by 2–3 times, and the efficiency of boring and burnishing is about 3 times higher than grinding. These data demonstrate that roller burnishing is a highly efficient process that significantly improves the surface quality of the cylinder.

After roller burnishing, the surface of the ATOS cylinder has no sharp micro-edges, and prolonged friction will not damage the seals or sealing components, which is particularly important in the hydraulic industry.

ATOS Cylinder Management:

The ATOS cylinder is a hydraulic actuator capable of reciprocating motion. How can hydraulic cylinders be effectively managed to maximize their performance? The analysis is as follows:

Regarding hydraulic systems, corresponding steps are required. Positioning components must be configured at the piston rod end, allowing positioning only at one end, thus losing widespread control in the hydraulic systems of various machines. This helps improve the working life of the hydraulic cylinder. Good dust prevention. When managing hydraulic cylinders, it is essential to ensure reliable sealing and use a gas leak alarm. The input force of a hydraulic cylinder is directly proportional to the effective area of ​​the piston and its pressure difference. A hydraulic cylinder is formed by a cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device, and exhaust device. Reciprocating oscillating motion can be achieved using a swing-type hydraulic cylinder. Good dust prevention measures are crucial to reduce processing difficulties. For example, an offensive load can compress the piston rod. The following points must be carefully considered: Maximize the load on the piston rod under tension, and ensure corrosion protection of the steel structure. Only then can a rough and reasonable management result be achieved.

Hydraulic cylinders have a simple structure and reliable operation. If a curved piston rod cannot be connected by threads, a double-piston rod hydraulic cylinder can be adopted. The management method for hydraulic cylinders involves detection and diagnosis. Stable movement and reliable sealing are essential factors for the operation of the hydraulic cylinder. For the motion shape of the hydraulic cylinder, differential connection can be considered, or some transmission devices can be used to reduce the travel distance.
