Switzerland rolling mill cylinder

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

rolling mill cylinder are widely used in Switzerland,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed rolling mill cylinder for customers from Switzerland.

Introduction to rolling mill cylinder:

rolling mill cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a rolling mill cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' rolling mill cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the rolling mill cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The rolling mill cylinder mainly outputs linear motion and force. The rolling mill cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston rolling mill cylinder, plunger rolling mill cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger rolling mill cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

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

The rolling mill cylinder is not the same as the rolling mill cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the rolling mill cylinder can not be used as a high-power power component, but the rolling mill cylinder can be used as a relatively large power component, or the rolling mill cylinder system can be used.

Regular maintenance of the rolling mill cylinder includes: regular tightening, rolling mill cylinder fastening screws and gland screws, rolling mill cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the rolling mill cylinder once a year. Clean regularly, the rolling mill cylinder is cleaned every other year, and the seals are replaced while cleaning.

Answers to some questions about rolling mill cylinder:

By what means can the hydraulic system control the arbitrary stroke position of the rotary cylinder piston rod?
The following ways can be considered: 1, through the limit device, such as limit switch, position sensor, etc. 2, by feedback the pressure of the hydraulic oil in the cylinder. The load determines the pressure, the pressure in the cylinder is determined by the load, and the pressure is very small when the cylinder is unloaded. 2.1 When clamping the workpiece, the pressure of the cylinder increases, by calculating the relationship between the clamping force and the pressure of the cylinder, take a pressure value of the cylinder, set the pressure switch, and drive the valve to work when the pressure reaches the preset value, so that the oil circuit stops supplying oil. 2.2 or set the pressure value of the relief valve to overflow after a certain set pressure.

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.
