About Non -standard Hydraulic cylinder(Allows customization)

1.Definition

It is a kind of pressure finishing process, which uses the cold plastic characteristics of metal at room temperature, and uses a rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills it to the original residual low In the concave wave trough, the surface roughness of the workpiece is reduced. Due to the plastic deformation of the rolled surface metal, the surface structure is cold hardened and the crystal grains become finer, forming a dense fiber shape, and forming a residual stress layer, which improves the hardness and strength, thereby improving the wear resistance and corrosion resistance of the workpiece surface Sex and coordination.

2.Introduction

The actuator in the cylinder hydraulic system.

Its components are mainly composed of:

Chinese: Piston Rod

English: ROD

Chinese: cylinder head

English: ROD COVER

Chinese: Piston

English: PISTON

Chinese: Seal

Hydraulic cylinder

Hydraulic cylinder

English: SEAL

1. The TUBE consists of four parts:

1. Cylinder block 2. Flange 3. Cylinder bottom 4. Bushing

2. The piston rod (ROD) consists of three parts:

1. Rod body 2. Earring 3. Bushing

The above parts are composed; the inside of the cylinder is divided into two parts by the piston, a large cavity and a small cavity;

Large cavity refers to the inner cavity of the cylinder after the piston rod is fully extended;

The small cavity refers to the inner cavity of the cylinder and the rod after the piston rod is fully extended;

Due to the relatively high viscosity of hydraulic oil and the small compression ratio, when the oil port at the bottom of the cylinder enters the oil, the piston will be pushed to make the oil port of the cylinder head come out, and the piston drives the piston rod to extend or retract, and vice versa .

Working principle

Let me talk about its five most basic components: cylinder and cylinder head, piston and piston rod, sealing device, buffer device, and exhaust device.

Use range

It can directly perform pressure test on pressure vessels, equipped with special tools for lifting, bending, straightening, extrusion, shearing, riveting, jacking, stretching, disassembly, punching, construction steel bar extrusion, bridges, Various operations such as construction machinery.

Precautions

Before hydraulic cylinders, you should make preparations. The first is to relieve the pressure of the hydraulic circuit, otherwise when the oil pipe joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be sprayed out quickly. When depressurizing the hydraulic circuit, first loosen the handwheel or pressure regulating screw at the relief valve, etc., to unload the pressure oil, and then cut off the power or power source to stop the hydraulic device.
