Germany hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder(Germany synchronous hydraulic cylinder,produced by Hengyu Group)
synchronous hydraulic cylinder are widely used in Germany,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed synchronous hydraulic cylinder for customers from Germany.
The synchronous hydraulic cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure synchronous hydraulic cylinder can use 20 steel pipe, and the high pressure synchronous hydraulic cylinder can use 45 steel pipe.
The coordination of the sliding parts of the synchronous hydraulic cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.
If the synchronous hydraulic cylinder slips or crawls, please check whether there is astringency inside the synchronous hydraulic cylinder, because the internal parts of the synchronous hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the synchronous hydraulic cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the synchronous hydraulic cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.
The advantages and disadvantages of the synchronous hydraulic cylinder: the surface of the synchronous hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the synchronous hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.
Why the injection cylinder retreating after the injection molding machine is started?
It is likely that the projected area of the molded plastic parts is large or the injection pressure set is relatively large, resulting in the expansion force exceeding the clamping force of the injection molding machine, so the mold is backward. You can do the following attempts: 1, reduce the injection force of the injection molding machine; 2, if the injection molding part can not be well formed by reducing the injection force, it is recommended to install the mold to a larger injection molding machine.
What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.
