(S.Africa rolling mill cylinder,produced by Hengyu Hydraulic Co., Ltd）

rolling mill cylinder are widely used in S.Africa，because of powerful torque，excellent temperature resistance，no transmission clearance.So our company has designed rolling mill cylinder for customers from S.Africa.

Introduction to rolling mill cylinder:

In recent years, the processing process of the rolling 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.

Causes and countermeasures of oil rolling mill cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the rolling mill cylinder will lead to premature wear of the piston seal, replace the piston seal; If the rolling mill cylinder is visibly scarred, the rolling mill cylinder must be replaced. It can be pressurized at one end of the rolling mill cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most rolling mill cylinder piston drift may not come from the rolling mill cylinder, the above method to determine the rolling mill cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

rolling mill cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the rolling mill cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the rolling mill cylinder. c. The rolling mill cylinder seal is extruded, if the O-ring is obviously extruded at the rolling mill cylinder seal, replace the rolling mill cylinder seal.

Piston rolling mill cylinder is widely used in hydraulic transmission. When the rolling mill cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the rolling mill cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the rolling mill cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

Answers to some questions about rolling mill cylinder:

Need to buy a hydraulic cylinder, now only know that the pressure needs to be between 20t and 50t. Two-way travel, how to determine the type of cylinder?
Important parameters of the cylinder: cylinder diameter, stroke, use pressure. First, the system pressure must be determined according to the precision of the operation of the application equipment, and the cylinder diameter can be determined by the force and system pressure. Then, according to how the equipment and the cylinder are installed and connected, determine the installation method of the cylinder and then determine the specific installation size, the size of the oil port, whether the buffer is needed and other details.

What is hydraulic cylinder guide?
The cylinder itself can not move, the piston moves, the guide should be used to guide the mechanism connected with the piston extension end. For example, in the commonly used hydraulic press, the guide column above is used to guide the pressure plate connected with the piston.
