In the oil cylinder piston rod is made of what material?
Oil cylinder (can also be called a hydraulic cylinder) is actually a convert hydraulic energy to mechanical energy, making an oscillating motion or a linear reciprocating motion of a hydraulic actuators. The oil cylinder piston rod is applied in the oil cylinder movement execution parts in a kind of moving parts, its main function is to achieve a force transfer.
In the oil cylinder piston rod mainly adopts the following materials:
1, 45 steel.
In the oil cylinder piston rod in most cases, are using 45 # steel to make, and general design into the cylinder. If for corrosion resistance requirements of the oil cylinder piston rod is higher, can use in a layer of hard chrome plated piston rod working surface to improve its ability to resist corrosion. And, when necessary, also can undertake conditioning treatment, because conditioning can effectively improve the work strength and improve the machining performance.
2, 40 cr steel.
40 cr steel is commonly used in the oil cylinder piston rod of a manufacturing material, it can be a reasonable is the most widely used in machinery manufacturing scope of one of the steel. Usually we just in the oil cylinder piston rod need a greater impact, heavy load transmission, only use the material for manufacturing oil cylinder piston rod. And use this kind of 40 cr steel manufacturing oil cylinder piston rod need to deal with just can use after quenched and tempered, tempering, the tempering temperature is 520 ℃ + 10 ℃, quenching temperature is 850 ℃ plus or minus 10 ℃. After tempering treatment, the oil cylinder piston rod has a good comprehensive mechanical properties, low temperature impact toughness, low notch sensitivity, so it is suitable for use in production of medium-sized plastic mold.
In the application of oil cylinder, oil cylinder piston rod of the role is very big, relative to other moving parts in the oil cylinder, oil cylinder piston rod movement more frequently, higher technical requirements. So choosing oil cylinder piston rod, should according to its needs to choose different materials produced, the piston rod.
Despite the arrival of Industry 4.0, there are still plenty of sectors where components are screwed together by hand. In shipbuilding, wind power systems and the rail and automotive sectors, there are always plenty of these screw fixings that stubbornly refuse to come undone. Mechanics all have their own special tricks for getting to grips with stuck screws – and one of the most popular is to apply heat. The BETEX iDuctor that Dutch company BEGA International is unveiling at HANNOVER MESSE 2017 heats metal parts in a very simple and accurate process.
As its name implies, the BETEX iDuctor uses induction technology to heat all kinds of metal parts, without contact or flames. Whether small drive components, bearing housings, nuts, bolts, pipes, screws or other small surfaces – the machine heats them until they glow red, if required, in a matter of seconds. The user-friendly, handheld BETEX iDuctor features overload protection and its power can be adjusted steplessly according to requirements. The iDuctor is supplied in a handy plastic carrying case complete with a two-meter-long flexible inductor and a pair of heat-resistant gloves.
As the power transmission industry in ASIA first and the second international professional exhibition in the world, ASIA international power transmission and control technology exhibition (PTC ASIA) has always been adhering to the HANNOVER MESSE in Germany HANNOVER MESSE () in the advanced concept of science and technology, innovation and good faith service, based on the Chinese market, provide the exhibitors with high-end professional display platform. Continuous development in the global economy, purchasing trend to expand under the background of globalization, fully understand the market demand for flexible innovation based components, building enterprise display platform at the same time focus on the user and the buyer, provide the market with the best space cooperation in trade.
Since the first held in 1991, the exhibition from every two years to the development every year, rising in exhibition area, exhibits, professional audience duplication and greatly promoted the power transmission and control technology international exchange market and the development of the trade market. The exhibition not only for many international brands to enter China and Asia market provides opportunities and an excellent platform more market in China has brought the global procurement.
ydraulic cylinder need to adopt sealed because its internal leakage and external leakage problems, when the hydraulic cylinder of internal leakage and external leakage happens, will cause the hydraulic cylinder cavity volume smaller lower efficiency, lower the hydraulic cylinder performance at work. In severe cases, generated when the system pressure will not work. Standing in the point of view of environmental protection at the same time, also want to try to avoid leaks, so it is very important to seal measures should be taken.
In the part of the main seal is the piston in the hydraulic cylinder, piston rod, end cover, etc. And usually adopts hydraulic cylinder seal there are three kinds of way, this also is today a high-tech rubber company is the main purpose of writing this article, introduce several ways used in the hydraulic cylinder seal.
First of all, using the first way is referred to as seal clearance, its working principle is in will keep a little space between the two moving parts, the liquid friction resistance in the gap to prevent leakage. This method has some disadvantages, is only applicable to small hydraulic cylinder and the piston diameter and pressure between seal and advantage in order to improve the efficiency of the seal will leave a few groove on the piston, the groove will let the oil change in internal leakage path or truncate, in a small groove form vortex and produce resistance, and reduce the oil leakage; On the other hand is to prevent piston axis deviation, thus to keep fit clearance, ensure lubricating effect, reduce the wear of the piston and cylinder wall, increase the gap sealing performance.
