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

Introduction to swager cylinder:

swager cylinder is the most important part of construction machinery, the traditional processing method is: broaching swager cylinder block - fine boring swager cylinder block - grinding swager cylinder block. The rolling method is: broaching swager cylinder block - fine boring swager cylinder block - rolling swager cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the swager cylinder block is about 1-2 days, rolling 1 meter of the swager cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the swager cylinder increases by 25%. If the swager cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality swager cylinders, you must take the rolling production process. After the swager cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

If it is found that the swager cylinder lubrication is poor or the swager cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the swager cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the swager cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the swager cylinder center line. In this way, when the piston works in the swager cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the swager cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Protection of the swager cylinder surface: During the dismantling process, safety protection should be carried out on the swager cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the swager cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the swager cylinder should be cleaned up in time.

Under normal circumstances, the swager cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the swager cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the swager cylinder and the end cover, the piston and the piston rod, the piston and the swager cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the swager cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about swager cylinder:

How to disassemble the big nut that excavate the oil cylinder piston of the excavator?
If you want to be safe, look for a special unloading place for this thing, which is an oil cylinder on top of a turntable with a large nut attached to the center of the turntable. If you're in the field just pin the head of the cylinder to one end, use a big homemade wrench to hold the nut in place, and then get a digging machine and push it down, and it opens.

In hydraulic equipment, is the motor power related to the cylinder pressure holding time?
Irrelevant. The motor only drives the plunger in the hydraulic cylinder of the oil pump to extend out, and stops when the set pressure is reached; The length of the pressure holding time is related to the sealing degree of the hydraulic cylinder and the solenoid valve.
