(Turkmenistan rolling mill cylinder,produced by Hengyu Group）

rolling mill cylinder are widely used in Turkmenistan，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed rolling mill cylinder for customers from Turkmenistan.

Introduction to rolling mill cylinder:

What kind of process is used in the rolling mill cylinder to make high-quality rolling mill cylinder products: the body is the main component of the rolling mill cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The rolling mill cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the rolling mill cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the 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 RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the rolling mill cylinder increases by 25%. If the service life of the rolling mill cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. rolling mill cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the rolling mill cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and rolling mill cylinder are stuck or the rolling mill cylinder is blocked. At this time, no matter how to manipulate, the rolling mill cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the rolling mill cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

The rolling mill cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

When purchasing the rolling mill cylinder, try to clarify the following parameters of the rolling mill cylinder: A. rolling mill cylinder diameter, rod diameter, stroke; B. Working pressure or rolling mill cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right rolling mill cylinder type can be found accurately and quickly.

If the piston rod and rolling mill cylinder are stuck or the rolling mill cylinder is blocked, at this time, no matter how to operate, the rolling mill cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the rolling mill cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about rolling mill cylinder:

How is the hydraulic cylinder selected in the mechanical design manual?
First of all, it is necessary to meet your work needs, and the second is to meet the structural space of the cylinder and accessories. Three to consider the other parameters of the cylinder.

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
