(Indonesia folding machine cylinder,produced by Hebei Hengyu company）

folding machine cylinder are widely used in Indonesia，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed folding machine cylinder for customers from Indonesia.

Introduction to folding machine cylinder:

There are some honeycomb holes in the inner wall of the folding machine cylinder, piston or piston rod surface. How is this formed? When we repair the folding machine cylinder, we can see that there are some honeycomb holes on the inner wall of the folding machine cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the folding machine cylinder is targeted to prevent. Is very necessary.

folding machine cylinder is the most important part of construction machinery, the traditional processing method is: broaching folding machine cylinder block - fine boring folding machine cylinder block - grinding folding machine cylinder block. The rolling method is: broaching folding machine cylinder block - fine boring folding machine cylinder block - rolling folding machine cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the folding machine cylinder block is about 1-2 days, rolling 1 meter of the folding machine cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the folding machine cylinder increases by 25%. If the folding machine cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality folding machine cylinders, you must take the rolling production process. After the folding machine cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

How to determine the working pressure of the folding machine cylinder: The pressure depends on the load size (i.e., F) and the type of equipment. The limitations of assembly space, economic conditions and component availability of the actuator should also be considered. In the case of a certain load, it is necessary to increase the structural size of the actuator if the working pressure is low, for some equipment, the size may be limited, and it is not economical from the point of view of material consumption; On the contrary, if the pressure selection is too high, the material, sealing and manufacturing accuracy of the pump, folding machine cylinder, valve and other components are also required to be high, which will inevitably increase the cost of equipment. In general, for equipment with a fixed size that is not too limited, the pressure can be selected lower, and the walking machinery should be selected higher.

In use, the folding machine cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the folding machine cylinder.

Answers to some questions about folding machine cylinder:

How does the cylinder of the shearing machine work?
Plate shear is a machine that cuts a sheet with a reciprocating straight motion from one blade to another. Through the moving upper blade and the fixed lower blade, the shear force is applied to the metal sheet of various thicknesses with a reasonable blade gap, so that the sheet is broken and separated according to the required size. Shearing machine belongs to one of the forging machinery, the main role is the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment. Working principle: The hydraulic system is used to drive the hydraulic cylinder to output a strong shear force to complete the shearing work.

How does the variable amplitude cylinder work?
The variable amplitude cylinder is generally an engineering hydraulic cylinder connected by the front and back earrings, and the telescopic expansion of the hydraulic cylinder changes the Angle of the arm of the lifting machinery to achieve the role of the variable amplitude, according to the role it plays is called the variable amplitude cylinder, and there is no variable amplitude hydraulic cylinder in the classification of hydraulic cylinders.
