(Chile steel mill cylinder,produced by Hengyu Hydraulic Cylinder Factory）

steel mill cylinder are widely used in Chile，because of no need for deceleration device，long service life，smooth movement.So our company has designed steel mill cylinder for customers from Chile.

Introduction to steel mill cylinder:

If it is found that the steel mill cylinder lubrication is poor or the steel mill cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the steel mill cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the steel mill cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the steel mill cylinder center line. In this way, when the piston works in the steel mill cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the steel mill cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Before the steel mill cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

The material, shape and compression of the steel mill cylinder seal have a great impact on the service life and work efficiency of the steel mill cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

steel mill cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards steel mill cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the steel mill cylinder guide is determined by the length of the stroke. Check the strength of steel mill cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

Answers to some questions about steel mill cylinder:

About the hydraulic cylinder wall thickness problem?
Hydraulic cylinder wall thickness calculation formula: t=PD/200St= pipe wall thickness (minimum thickness) mmP= maximum pressure kg/cm2? d= inner diameter mm? S=δ/5 safety factor δ= minimum tensile strength This case: set the cylinder material 45#, tensile strength 58kg/cm2t=(640X40)/(200X11.6)t=11mm piston output (i.e. Thrust) calculation formula: F1=PD2X(3.14/4)F1=640X42X0.785=8,038kg Note: Square numbers will not be used, all 2's in the text are square codes.

What is the role of the cylinder on the plastic mold? The oil cylinder plays a great role in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the oil cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product, sometimes customers require to use hot runner, the price is more expensive, but there are many benefits. It can save raw materials and shorten the molding cycle.
