Engineering Machinery Parts Cylinder To The Research And Application Of Remanufacturing

Since entering the 21 st century, China’s industrial development is high-speed forward, the economy is also developing rapidly, the scale is also growing, demand for energy and resources is increasing, demand for energy and resources more and more high, and Chinese population per capita resources with the world average level there is a big gap. Arable land, water resources, coal resources, oil and other resources already have been in short supply, the energy crisis and resource depletion phenomenon is increasingly clear, natural resources are particularly vulnerable, China’s average annual consumption of coal, steel and other resources accounted for more than the world’s total 1/3, the future will develop seriously restricting China’s economic. Cars scrapped each year, engineering machinery and the number is increasing year by year, these waste products will not only take up a lot of the area, but also cause the waste of resources, long time exposure will pollute the soil in the air. In order to alleviate the energy crisis and resource shortage, must be on the waste products re manufacturing technology to repair, restore its performance.Remanufacturing is to fix it on the basis of waste products through product comparison process forward and reverse the process of highlighting its contribution to energy saving and environmental aspects of the role is very great, the implementation is essential remanufacturing is also very important, and promotion of the use of remanufactured to meet the needs of sustainable development, see remanufactured products industries in the future will be, it will play an increasingly important role.Make a detailed analysis of this paper on the process of remanufacturing engineering machinery, and method of manufacturing and remanufacturing used on each process are introduced, and the processing principle of commonly used to manufacture processing technology is described. Hydraulic cylinder as an important component of construction machinery output, high concentration of the fuel tank, and then manufactures a large value. Dismantling scrapped tanks, cleaning and testing, to re-manufacturing standard cylinder honing remanufacturing, ensure its roundness and roughness meet the technical requirements of new products, cylinder honing theory after the first check, and then use ANSYS stress and strain analysis. Remanufacturing rod must first be straightened, electricity plating technology for surface repair, reasonable processing parameters by orthogonal experiment. Remanufactured parts processed for assembly, assembled cylinder in the cylinder test bench for testing the indicators to verify the feasibility of re-manufacturing of hydraulic cylinders.
