Cylinder tube manufacturers brand

Cylinder tube manufacturers brand sales hotline: 13676382696 cylinder tube production generally talked complex process and strict testing to production, because it is used in the production of a variety of mechanical parts, so the cylinder tube high precision. With the continuous development of technology, the cylinder tube manufacturing process continues to progress perfect for the cylinder tube production efficiency has a great role in promoting. In order to make more productive cylinder tube, we adopted a new production process, through the powerful grinding, polishing automated way to produce. Which also includes the use of automated grinding electricity or ultrasonic grinding way to complete production tasks. Good production process, for production efficiency is inevitable, in recent years, we have used more than a few ways to produce abrasive grinding tube, was a great success, for grinding cylindrical inner circle is no longer a problem, I believe in our continued efforts, we can achieve better process development. Daily works cylinder tube is mainly generated by a certain pressure on the sand belt, surface grinding performed under a certain speed. By moving up and down the belt on the upper and lower surfaces of the workpiece back and forth grinding, to achieve a certain effect. Of course, in the grinding process to continuously add oil, cooling, so as not to affect the workpiece surface quality. Such artifacts just get rough parts, precision products need to want better finishing treatment tanks are the most important parts of construction machinery, traditional processing methods are: Broaching cylinder - fine boring cylinder - mill cut the cylinder. Using rolling method is: Broaching cylinder - fine boring cylinder - rolling cylinder, step three parts, but the contrast in time: grinding cylinder about 1 m in 1-2 days, rolling cylinder 1 meter in about 10-30 minutes. Investment comparison: quilting grinder or mill (tens of thousands - millions), rolling knife (a thousand - tens of thousands). After rolling, the surface roughness of the hole by rolling before Ra3.2 ~ 6.3um buildings reduced to Ra0.4 ~ 0.8 & surface hardness um, hole by about 30%, the cylinder surface fatigue strength by 25%. If only consider the cylinder cylinder life impact, increased by 2 to 3 times rolling process is relatively boring grinding efficiency is about 3 times. The above data shows that the rolling process is efficient and can greatly improve the surface quality of the cylinder. After rolling the cylinder surface is no small sharp edge for a long time and will not damage the movement friction seals or seals, which is especially important in the hydraulic industry. No matter what the fuel tank cylinder processing method for processing, the part surface always leave fine uneven marks, staggered undulating valley phenomenon, rolling processing principle: it is a kind of pressure finishing, is the use of metal plasticity characteristics at room temperature in a cold state, the use of rolling tool to exert pressure on the surface of the workpiece surface metal plastic flow, fill the remaining low-lying valleys to the original, rather reach the surface roughness values ??decrease. Because the surface is rolled metal plastic deformation, so cold hardening and grain tapering surface tissue, forming a dense fibrous, and the formation of residual stress layer, hardness and strength increased, thereby improving the wear resistance of the workpiece surface, corrosion and with nature. Rolling is a non-cutting plastic working method. No machining technology safe, convenient and precise control precision, several major advantages: 1, to improve the surface roughness, roughness can basically reach Ra≤0.08μm. 2, the amendment roundness, ovality can ≤0.01mm. 3, to improve the surface hardness, so that by eliminating deformation, hardness HV≥4 ° 4, after processing residual stress layer, improve the fatigue strength by 30%. 5, to improve with the quality and reduce wear and extend the life of parts, but the parts but lower processing costs. Heavy tanks (HOB) - the use of pressure 14Mpa, thin cylinder (JOB) - the use of pressure 14Mpa, a small circular cylinder (SOB) - Pressure 7Mpa, large circular tanks (ROB, COB) - super high pressure using a pressure 14Mpa round cylinder (HSOB, HROB) - Pressure 21Mpa vehicle lift cylinder cylinder cylinder injection molding machines of various molds, silicone rubber molding machines, die casting machines, balers and other marine cylinder machine cylinder hydraulic cylinder parts for various purposes www.sdxzgg.com www.lcxzggc.com www.hmg6.com www.lcygg.com www.fsw-zy.cn www.hnlcgg.com www.hmggs.com www.hmgongju.com www.dwymg.com www.xzymg.com
