press machine hydraulic cylinder are widely used in Sweden,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed press machine hydraulic cylinder for customers from Sweden.

Introduction to press machine hydraulic cylinder:

In the process of using the press machine hydraulic cylinder, sometimes such a problem will occur, the press machine hydraulic cylinder can not act immediately after the instruction of the press machine hydraulic cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil press machine hydraulic cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

The body of the press machine hydraulic cylinder on the processing process requirements: the body of the press machine hydraulic cylinder is an important and essential part of the press machine hydraulic cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the press machine hydraulic cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

The press machine hydraulic cylinder is mainly composed of body, piston, piston rod, press machine hydraulic cylinder head, press machine hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the press machine hydraulic cylinder into two chambers, and moves reciprocally in the press machine hydraulic 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 press machine hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the press machine hydraulic 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 press machine hydraulic 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 press machine hydraulic cylinder bottom and the press machine hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the press machine hydraulic cylinder The working medium of the press machine hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; press machine hydraulic 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 press machine hydraulic cylinder: The buffer structure of the press machine hydraulic cylinder is to prevent the piston from colliding with the press machine hydraulic cylinder head at the end of the stroke.

When the control pressure of the hydraulic system is too low, the press machine hydraulic cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

Answers to some questions about press machine hydraulic cylinder:

What welding rod is used for hydraulic cylinder welding?
There are several reasons for bad welding of hydraulic cylinder: 1. There is hydraulic oil on the welding surface, wipe it with a rag, there will be bubbles in the welding process, and it will not last for a few days. You have to remove it, drain it, wash it off with gasoline and try again. 2. Open the groove before welding, it is not deep enough to use the Angle grinding machine, and can not find the accurate crack position. 3. The material of the cylinder itself is not clear, the welding performance of more than 35 steel is not good, in the factory welding needs to preheat, the welding rod should also be dried and insulated, there is no such condition on the site.

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.
