Argentina hydraulic cylinder,punch machine hydraulic cylinder manufacturer,punch machine hydraulic cylinder(Argentina punch machine hydraulic cylinder,produced by Hengyu Group)
punch machine hydraulic cylinder are widely used in Argentina,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed punch machine hydraulic cylinder for customers from Argentina.
The difference between the plunger punch machine hydraulic cylinder and the piston punch machine hydraulic cylinder is that the piston in the punch machine hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type punch machine hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.
punch machine hydraulic cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a punch machine hydraulic cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' punch machine hydraulic cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the punch machine hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The punch machine hydraulic cylinder mainly outputs linear motion and force. The punch machine hydraulic cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston punch machine hydraulic cylinder, plunger punch machine hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger punch machine hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
When the initial action of the punch machine hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the punch machine hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.
The punch machine hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the punch machine hydraulic cylinder should pay attention to: the operation should be as far away from the punch machine hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the punch machine hydraulic cylinder coating. When cleaning the punch machine hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the punch machine hydraulic cylinder when the oil temperature exceeds 70 ° C.
Need a hydraulic cylinder, vertical upward 10 seconds to lift 20 tons of weight up 2 meters, how large cylinder and rod, how much pressure to use the plunger pump and how big?
The first thing to determine the system pressure, let's say 25 mpa, can take into account cost and performance. 1 Cylinder area 20000/250=80 square cm cylinder diameter (80/3.14) squared x2=200 mm 2 cylinder volume 80x200=16000 ml =16 L 3 Required pump flow 16x60/10=96 L/min 4 Power 96x25/55=43 kW 45 kW motor is available.
What is the difference between hollow and solid oil cylinders?
Hollow solid cylinder, according to conventional understanding, refers to whether the piston rod is solid or hollow. General ordinary hydraulic cylinder, the piston rod is solid structure. Hollow hydraulic cylinder refers to a hollow piston rod structure of the hydraulic cylinder, see the attached figure. Piston rod hollow function: 1, the piston rod hollow, the middle can be threaded rod. For example, the clamping cylinder with a sawing machine, the piston rod center threading rod, part of the stroke through manual, part of the stroke hydraulic automatic walk. 2, the hollow hole of the piston rod can be used to direct the oil circuit to achieve special oil circuit. 3, the cylinder is relatively large, the piston rod is relatively large, and the stroke is longer, in this case, the piston rod is hollow to reduce the movement friction and lateral force.
