With the healthy and orderly development of the wind power equipment manufacturing industry, the demand for high-end CNC machine tools will have a double improvement in quality and quantity. In order to further break through the technology of the wind power equipment manufacturing industry, the advanced and precise machine tools are indispensable. This also means an accelerated upgrade of the Chinese machine tool industry. It has many advantages, such as flame retardant, non-toxic, corrosion-resistant, small volume-weight, low thermal conductivity, strong chemical stability, low moisture absorption rate, good hydrophobicity and so on. It is recognized as the most superior thermal insulation and sound-absorbing material with a wide range of applications. The board, felt and tube made of this material have been widely used in thermal insulation and noise reduction in the fields of construction, chemical industry, electronics, electric power, metallurgy, energy, transportation, etc. Fiberglass Wool Insulation,Glass Wool Density,Glass Wool Thermal Insulation Zhengzhou Ou Nuo Building Materials Co., Ltd. , https://www.jcyuounuo.com
The gearbox of wind power equipment is mainly composed of a box body, a planetary gear train and a shifting mechanism. The gearbox body belongs to a large box body, and its structure is complicated. The manufacture of various components requires different machine tool equipment for processing. The megawatt-class wind power equipment gearbox has a diameter of about 2 to 3 meters depending on the amount of power generation, and most of them are separated structures. CNC machining, floor milling and boring machine with large diameter of 160~250 mm, large horizontal machining center and gantry machining center are required for machining. Large-size, large-modulus gears and ring gears need to be machined using CNC forming and milling machines and CNC forming gear grinding machines. Among them, CNC forming and milling machine requires large depth of cut, large feed and high rolling speed; CNC forming gear grinding machine requires precision of 5 or above, requiring automatic self-aligning, automatic measurement, automatic shaping and other high degree of automation and high stability. .
For the machining of large blades, CNC milling machines are required. These machines are large-scale light non-metal five-axis machining machines. Although the machining accuracy is not high and the power and torque are small, the cutting speed of the machine is very high. The cutting speed is high. 30 m / min or more. The machining of the rotor shaft of the motor requires a large-scale horizontal milling and milling machine. It is necessary to increase the milling and grinding functions on the basis of the traditional horizontal lathe to achieve one-time clamping. The stator manufacturing requires vertical turning and milling. The machining of machine tools, especially the stator undercuts, requires milling and grinding functions on the basis of conventional vertical lathes. It also requires a single clamping process.
The main shaft, the wind wheel and the tower are large components, which are difficult to process and require high precision. Specially designed special processing equipment is required, and it has high speed, high efficiency, intelligence, flexibility, automatic conversion of CAD/CAM, automatic A number of advanced features such as detection, error compensation and automatic fault diagnosis.
For a long time, the above-mentioned processing equipment has basically relied on import solutions, resulting in an increase in the cost of manufacturing wind power equipment. With the continuous improvement of the industrialization level of wind power equipment, the proportion of localization has increased rapidly, which has promoted the rapid development of the wind power market and provided new opportunities for the development of the machine tool industry. In recent years, in response to the processing of wind power industry parts and components, China's machine tool industry is actively researching and developing some processing equipment with independent intellectual property rights. Its processing precision, efficiency and stability are comparable to imported equipment.
