ATOS Hydraulic Cylinder Selection Technical Parameters

ATOS 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 complete 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, a piston and piston rod, sealing devices, cushioning devices, and venting devices. Buffer devices and venting devices depend on the specific application; other devices are...

1. Cylinder Diameter: Cylinder bore, inner diameter.

2. Inlet/outlet diameter and thread parameters.

3. Piston rod diameter.

4. Cylinder Pressure: Cylinder working pressure. Calculations often use test pressure; below 16MPa, multiply by 1.5; above 16MPa, multiply by 1.25.

5. Cylinder Stroke.

6. Buffering: Determined by working conditions. Buffering is generally required if the piston rod extension/retraction has a large impact.

7. Cylinder Installation Method.

ATOS Cylinder Machining: As a key component in products such as hydraulic cylinders, mining single-support pillars, hydraulic supports, and blasting barrels, the quality of cylinder machining directly affects the lifespan and reliability of the entire product. Cylinder machining requires high precision; the inner surface roughness must be Ra0.4～0.8µm, and strict requirements must be placed on coaxiality and wear resistance. A fundamental characteristic of cylinder machining is deep hole machining, which has always been a challenge for machinists. Roller burnishing, by leaving residual compressive stress on the surface layer, helps to close micro-cracks and hinders the propagation of corrosion. This improves surface corrosion resistance and delays the initiation or propagation of fatigue cracks, thus increasing the fatigue strength of the cylinder. Through roller burnishing, a work-hardened layer is formed on the surface, reducing the elastic and plastic deformation of the contact surfaces of the grinding pairs, thereby improving the wear resistance of the cylinder inner wall and preventing burns caused by grinding. The reduced surface roughness after roller burnishing improves the fit.

ATOS Cylinder Working Principle:

The working principle of a hydraulic cylinder mainly involves five components. Let's start with its five most basic components: 1- Cylinder barrel and cylinder head, 2- Piston and piston rod, 3- Sealing device, 4- Buffer device, 5- Exhaust device.

The working principle of each type of cylinder is almost similar. Take a manual jack as an example; a jack is essentially a simple hydraulic cylinder. The hydraulic oil is fed into the cylinder through a one-way valve by a manual booster rod (hydraulic manual pump). Because of the one-way valve, the hydraulic oil cannot flow back into the cylinder, forcing the cylinder rod upwards. During operation, the hydraulic oil continues to flow into the cylinder, rising continuously. To lower the cylinder, the hydraulic valve is opened, allowing the hydraulic oil to return to the tank. This is the basic working principle. Other systems are improvements on this principle. The principles of pneumatic and hydraulic cylinders are basically the same. [1]

ATOS Cylinder Machining:

Trundle Processing

Trundle processing is a non-cutting process that utilizes the plastic deformation of metal at room temperature to smooth out the micro-irregularities on the workpiece surface, thereby changing the surface structure, mechanical properties, shape, and size. Therefore, this method can simultaneously achieve both finishing and strengthening, which 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.

Rolling/Brushing Principle: It is a pressure finishing process that utilizes the cold plasticity of metal at room temperature. A rolling 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 rolled surface metal, the surface structure hardens and the grains become finer, 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. Rolling/Brushing 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-induced 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 lowering machining costs. CK-32/22*0040-P001 Hydraulic Cylinder
