At the meeting, Wang Fuchang, inspector of the Equipment Division of the Ministry of Industry and Information Technology and Cao Chunxiao, academician of the Chinese Academy of Sciences, highly praised the equipment.
The highest in Asia
On Sept. 6, at Xi'an Aerospace Power Machinery Factory, originally a state secrecy unit, with the help of SY-100L large-scale vertical CNC powerful spinning machine, the reporter observed the scene of the spinning process of large thin-walled parts .
"14 meters above the ground and 3 meters below the ground." The first impression given to reporters by this big machine is that it is mighty. As the main manufacturer of this equipment, Huang Guojun, Vice General Manager of Casting and Forging Sales Company of CITIC Heavy Industries, told reporters from a professional point of view that although this equipment is not very large compared with other large equipment products manufactured by the enterprise, The technical parameters of the request is very high. Multi-party participation, which lasted ten years of successful development, shows its weight and gold content. Moreover, as one hundred tons of spinning equipment, not only unique in our country, but also å ªç§° is the highest in Asia. At present, except for the United States and Russia in this technical field, only China can reach this level.
What is ten years grinding sword? Zhang Jun, Director of AVIC Beijing Institute of Aeronautical Manufacturing Engineering, introduced the development of large-scale vertical CNC powerful spinning equipment to meet the manufacturing needs of large-scale thin-walled slewing body parts in aerospace, aerospace, shipbuilding, nuclear industry and chemical industry. In order to solve the bottleneck of manufacturing large-thrust carrier rockets, missiles and aircraft engines, which are urgently needed by the national defense, and promote the application of the spinning components in large aircraft, aircraft engines, missiles and large-scale pressure vessels, China's strategic gap has been filled. In 2001, Xi'an Aerospace Power Machinery Plant started a large CNC powerful spinning machine development projects. In early 2004 formally and AVIC Beijing Aerospace Manufacturing Engineering Institute signed a contract for the development of equipment. The project was listed by the Ministry of Industry and Information Technology as one of the major topics for the national science and technology project entitled "High-end CNC Machine Tools and Basic Manufacturing Equipment" (hereinafter referred to as "04 CNC Machine Tool Project") for 2011. With the help of Zhejiang University, Wuhan Heavy Duty Machine Tool Co., Ltd., CITIC Heavy Industries, Jinan Second Machine Tool and other related components and units, AVIC Beijing Institute of Aeronautical Manufacturing Engineering and Xi'an Aerospace Power Machinery Factory overcame various difficulties and achieved the goal of implementing the " Into the user on-site assembly, in November 2012 to complete equipment static, dynamic and functional commissioning, began trial rotation.
Up till now, after more than half a year of spinning process test, the equipment has the advantages of high overall strength, good rigidity and high control accuracy, advanced functions such as synchronous feed, misalignment spinning and intelligent adjustment of spinning pressure. The overall performance is superior, Spin out of the parts of the performance indicators in line with the user's requirements, the rotary thrust and spin-on parts size of the highest in Asia.
Wang Decheng, vice president of Mechanical Science Research Institute, spoke highly of the success of this equipment. He said that it is a new breakthrough in the field of spinning equipment since the "04 CNC Machine Tool Special" following the 36,000-ton extruder and the 80,000-ton forging machine. The successful development of this project has realized two major breakthroughs in technology and equipment. The first is a technological breakthrough. If two years ago, "04 CNC Machine Tool Project" to achieve a squeeze process, a breakthrough forging process, today achieved a new breakthrough in the spinning process. This is "04 CNC machine tools," a large-scale numerical control forming an important goal of this research.
Equipment breakthrough is mainly reflected in: It will effectively support the special needs in the aerospace, marine, power generation and automotive four major areas, the formation of large-scale thin-walled rotor parts needs. "04 CNC machine tool special" was aimed at four major areas of aerospace, shipbuilding, power generation and automotive. It should be said that this equipment has obviously broken the restriction of foreign technological blockade on the development bottlenecks in the above four major areas, made up for the deficiencies of the existing forming processes and equipment, and improved the covering capacity of large and complex sophisticated forming equipment.
User traction
Recalling the development process of ten years, experts involved in the development of equipment are all feeling, a large vertical CNC powerful spinning equipment with CNC machine tools, high-precision, heavy machine tools, such as strong stiffness and heavy load characteristics of research projects difficult, difficult to design, High precision, complex structure, difficult procurement of key parts, oversized parts, difficult manufacture, coordination of all units and departments, difficulty of assembly, large inspection difficulty, difficulty of commissioning and spinning, difficulty of funding, period It is constantly being adjusted and facing enormous challenges in all aspects. The successful development of large-scale vertical CNC powerful spinning machine indicates that China has reached a new height in the field of manufacturing technology of large thin-walled slewing body metal structural parts and is the result of the cooperation of production, study and research.
In addition to technological and equipment breakthroughs, Wang Decheng told reporters that the breakthrough in the project is also reflected in that it will become a successful example of the "04 CNC machine tool project" insisting on the cooperation model of production, learning and research. There are a number of technical cooperation in this equipment, including large castings and forgings, hydraulic controls, etc., each of which, as a separate technology, meets a "problem" of mass, are challenges, and should be said that all are right Extreme manufacturing challenges. Under the proposal of the special office, under the full organization of the lead unit, a cooperation advantage of production, learning and research has been formed.
At the same time, Wang Decheng also believed that the reserve which lasted 10 years eventually achieved breakthrough with the support of "04 CNC Machine Tool Special Project", proving once again that the state has set up major special projects, especially the "04 CNC Machine Tool Project," which will develop strategic emerging industries such as national defense and military industries Necessary and central role. High-end technology is not a single day, long-term preparation, can not do without state support.
Wang Fuchang agree. He said, "04 CNC machine tools special" in the implementation process, continue to explore, improve and adjust, the main emphasis on four aspects. First, the demand for traction, included in the special subject must be the national economy and national defense construction urgently needed, not to complete an indicator.
Second, the close combination of production, study and research, especially the close combination of the manufacturer and the user. Because manufacturing companies are not familiar with user needs and process issues, most of the topics currently scheduled are user-led.
Third, the host and CNC system, tools and other features combined. Although the domestically produced numerical control systems and functional components still have some shortcomings in practical applications, especially some of the major research projects are relatively high-end, we emphasize that we must give opportunities and each subject requires the participation of numerical control systems and functional components Into, the only way to make the domestic features "belt" up.
For granulating Machine, we usually use Fluid Bed Dryer Granualtor and Wet Granulator.They suit dry material and wet material separately.
The working principle of fluid bed dryer granulator is that the powder particles of the material are in a circular fluidized state in the raw material container (fluidized bed), and are preheated and mixed by the purified heated air, and the adhesive solution is atomized and sprayed, so that a number of particles are aggregated into For the agglomerates containing the binder, due to the continuous drying of the material by the hot air, the moisture in the agglomerates evaporates and the binder solidifies. This process is repeated continuously to form ideal and uniform microporous spherical particles.
