Uzbekistan steel mill cylinder

(Uzbekistan steel mill cylinder,produced by Hengyu Group)

steel mill cylinder are widely used in Uzbekistan,because of no need for deceleration device,high work efficiency,excellent fatigue and impact resistance.So our company has designed steel mill cylinder for customers from Uzbekistan.

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.

The steel mill cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the steel mill cylinder, bite. Elimination method: When installing the steel mill cylinder, ensure that the axis position of the steel mill cylinder is consistent with the direction of movement; Make the load borne by the steel mill cylinder as far as possible through the steel mill cylinder axis, to avoid the phenomenon of eccentricity.

In recent years, the processing process of the steel mill cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the 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 in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

Before purchasing the steel mill cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

Answers to some questions about steel mill cylinder:

What is the safety factor of 25MPa cylinder wall thickness?
Safety factor n can take 3 cylinder material allowable stress [s]=sb/n δ/D=0.08 ~ 0.3 cylinder wall thickness δ=PMAX*D/ (2.3[s]-3PMAX) δ/D≤0.08 cylinder wall thickness δ=PMAX*D/2[s] P < 16MPa, Pmax=1.5Pn; P > 16MPa, Pmax=1.25Pn cold-drawn tube or honing tube is better!

What should we pay attention to when using the cylinder?
When using the cylinder, we should pay attention to the environment and temperature in which it is located as follows: 1. Before working, the hydraulic cylinder must carry out several reciprocating movements under low pressure (greater than the starting pressure), and work normally after removing the gas in the cylinder. 2. Precautions when removing the hydraulic cylinder: ① The pressure in the hydraulic circuit is reduced to zero before disassembly. ② The screw thread at the top of the piston rod should be prevented from damage when disassembling. ③ Due to the different structure and size of the hydraulic cylinder, the order of disassembly is also slightly different. Generally, the fastening bolt of the end cover should be loosened first. Internal card chain card key application special tools.
