shearing machine cylinder are widely used in Slovakia，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed shearing machine cylinder for customers from Slovakia.

Introduction to shearing machine cylinder:

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

The cavitation of the shearing machine cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the shearing machine cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

The shearing machine cylinder is mainly composed of body, piston, piston rod, shearing machine cylinder head, shearing machine cylinder bottom, piston rod head and related auxiliary devices. The piston divides the shearing machine cylinder into two chambers, and moves reciprocally in the shearing machine cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the shearing machine cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the shearing machine cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the shearing machine cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the shearing machine cylinder bottom and the shearing machine cylinder head is serious, so the buffer deceleration should be set at both ends of the shearing machine cylinder The working medium of the shearing machine cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; shearing machine cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the shearing machine cylinder: The buffer structure of the shearing machine cylinder is to prevent the piston from colliding with the shearing machine cylinder head at the end of the stroke.

The repair method of shearing machine cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.

Answers to some questions about shearing machine cylinder:

How to control the speed of the hydraulic cylinder?
The speed of the hydraulic cylinder is only related to the flow, so the control speed is to control the flow of the hydraulic oil, which is generally adjusted by the throttle valve in the system.

How does the self-locking cylinder work?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil circuit itself is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
