Congo hydraulic cylinder,rolling mill cylinder manufacturer,rolling mill cylinder

(Congo rolling mill cylinder,produced by Hebei Hengyu company）

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

Introduction to rolling mill cylinder:

rolling mill cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the rolling mill cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

When using the rolling mill cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the rolling mill cylinder block. If the rolling mill cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the rolling mill cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the rolling mill cylinder, so that the working efficiency of the rolling mill cylinder is reduced.

rolling mill cylinder piston rod material introduction: In general, we use 45 steel to produce rolling mill cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

How to repair the rolling mill cylinder body when it is damaged: When the rolling mill cylinder has trace deformation and shallow tensile marks, the rolling mill cylinder is repaired by strong honing process. The heavy honing process can repair rolling mill cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the rolling mill cylinder can meet the technical requirements.

Answers to some questions about rolling mill cylinder:

What is the reason why the hydraulic cylinder is not good at lifting?
There may be several situations 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).

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.
