  • Detail

Several years after China's first large-scale powerful spinning machine passed the acceptance, combing the localization process of China's major equipment will become an important node on September 6, 2013. On that day, China's first large-scale powerful spinning equipment "sy-100l large vertical CNC powerful spinning machine" officially passed the acceptance of the user unit Aerospace Science and Technology Xi'an Aerospace Power Machinery Plant. After ten years of technical reserve and development, supported by the major scientific and technological project of "high-end CNC machine tools and basic manufacturing equipment", the 100 ton CNC spinning equipment has finally lived up to expectations, passed the user test and officially delivered for use

sponsored by the "high-end CNC machine tools and basic manufacturing equipment" science and technology major special implementation management office, and organized by AVIC Beijing Aerospace Manufacturing Engineering Research Institute, aerospace science and Technology Xi'an Aerospace Power Machinery Plant, AVIC aerospace special equipment R & D Engineering Center, and AVIC aerospace manufacturing technology center, the large-scale CNC powerful spinning equipment and technology application promotion conference was held in Xi'an on September 6. At the meeting, wangfuchang, an inspector of the equipment department of the Ministry of industry and information technology, and caochunxiao, an academician of the Chinese Academy of Sciences, spoke highly of the equipment

On September 6, Xi'an Aerospace Power Machinery Factory, which was originally a state secret unit, observed the spinning process of large thin-walled parts on site when accepting the sy-100l large-scale vertical CNC powerful spinning machine

"14 meters above the ground, 3 meters underground." The first impression this big machine gives is that it is powerful. As the main participant in the equipment manufacturing, huangguojun, deputy general manager of casting and Forging sales company of CITIC Heavy Industry Group, told from a professional point of view that although the volume of this equipment is not very large compared with other large equipment products manufactured by the enterprise, the requirements for technical parameters are very high. It has been successfully developed for ten years with the participation of many parties, which shows its weight and gold content. Moreover, as a 100 ton spinning equipment, it is not only unique in China, but also the best in Asia. At present, apart from the United States and Russia, only China can reach this level

what is the point of sharpening a sword in ten years? Zhang Jun, director of AVIC Beijing Institute of Aeronautical Manufacturing Engineering, introduced the development of large-scale vertical CNC powerful spinning equipment, which mainly meets the manufacturing needs of large-scale thin-wall rotary parts in aviation, aerospace, shipbuilding, nuclear industry, chemical industry and other industries. In order to solve the manufacturing bottleneck of high thrust launch vehicles, missiles and aircraft engines urgently needed by national defense, promote the application of spinning structural parts in large aircraft, aircraft engines, missiles and large pressure vessels, and fill the strategic gap in China, in 2001, Xi'an Aerospace Power Machinery Plant launched the development project of large-scale CNC powerful spinning machine tools. At the beginning of 2004, the company formally signed an equipment development contract with AVIC Beijing Aviation Manufacturing Engineering Research Institute. The project was listed as the 2011 Annual subject of the national major science and technology project of "high-end CNC machine tools and basic manufacturing equipment" (hereinafter referred to as "04 CNC machine tool project") by the Ministry of industry and information technology. With the strong assistance of Zhejiang University, Wuhan Heavy Machine Tool Co., Ltd., CITIC Heavy Industry, Jinan No. 2 machine tool and other relevant parts manufacturers, AVIC Beijing Institute of Aeronautical Manufacturing Engineering and Xi'an Aerospace Power Machinery Plant overcame various difficulties and realized the General Assembly at the user's site in november2011. In november2012, the static, dynamic and functional commissioning of the equipment was completed and the trial rotation began

up to now, the spinning process test for more than half a year has shown that the overall structure of the equipment has high strength, good rigidity and high control precision. It has advanced functions such as synchronous feed, stagger spinning and intelligent adjustment of spinning pressure. Its overall performance is superior. All performance indicators of the parts produced by spinning meet the user's requirements. Its spinning wheel thrust and spinning part size can be rated as the largest in Asia

wangdecheng, vice president of the General Research Institute of Mechanical Sciences, spoke highly of the success of the equipment. He said that it is a new breakthrough in spinning equipment after 36000 ton extruder and 80000 ton forging press in "04 CNC machine tool project". The successful development of the project has achieved two breakthroughs in technology and equipment. The first is the technological breakthrough. Two years ago, the "04 CNC machine tool project" achieved a breakthrough in extrusion process and forging process. Today, it has achieved a new breakthrough in spinning process. This is an important realization of the theme of "04 CNC machine tool project" large-scale CNC forming

the breakthrough of the equipment is mainly reflected in that it will strongly support the forming needs of large thin-wall rotating parts in the four special fields of aerospace, shipbuilding, power generation and automobile. The "04 CNC machine tool project" was aimed at the four fields of aerospace, shipbuilding, power generation and automobile. It should be said that the equipment has obviously broken the bottleneck of foreign technology blockade on the development of the above four fields. At present, the electronic tensile test mechanism is widely used, making up for the shortcomings of the existing forming process and equipment, and improving the coverage capacity of large-scale complex precision forming equipment

user traction

reviewing the development process of the past decade, all the experts involved in the equipment development lamented that the large-scale vertical CNC powerful spinning equipment has the characteristics of high precision of CNC machine tools, strong rigidity and heavy load of heavy machine tools. It is difficult to investigate and establish projects, difficult to design, high precision requirements and complex structure. China's only national automobile lightweight technology product internationalization, professional display platform and difficult to purchase key parts, The size of the parts is very large, the manufacturing is difficult, the cooperation and coordination of all units and departments is difficult, the assembly is difficult, the inspection is difficult, the commissioning and spinning is difficult, the funding is difficult, and the cycle is constantly adjusted, facing great challenges in all links. The successful development of large-scale vertical CNC powerful spinning machine marks that China has reached a new height in the field of manufacturing technology of large-scale thin-wall rotating metal structures. It is the result of cooperation between industry, University, research and application

in addition to the breakthrough in process and equipment, wangdecheng told that the breakthrough of the project is also reflected in that it will become a successful example of "04 CNC machine tool project" adhering to the cooperation mode of industry, University, research and application. In this equipment, there are a number of technical cooperation, including large castings and forgings, hydraulic control, etc. each of which, as a separate technology, meets the volume of a "problem" and is a challenge. It should be said that it is a challenge to extreme manufacturing. Under the suggestion of the special office and the full organization of the leading unit, the positive order is from high to low, which has become the cooperation advantage of industry, University, research and application

wangdecheng also believes that after 10 years of reserves, a breakthrough was finally made with the support of the "04 CNC machine tool project", which once again proves that the establishment of major projects, especially the "04 CNC machine tool project", has played a necessary and core role in the development of strategic emerging industries such as national defense and military industry since this year. High end technology is not a day's work. Long term preparation is inseparable from national support

wangfuchang agrees. He said that during the implementation of the "04 CNC machine tool project", continuous exploration, improvement and adjustment have been made, mainly focusing on four aspects. First, demand traction. The topics listed in the special projects must be urgently needed by the national economy and national defense construction, rather than to complete a certain index

the second is the close combination of production, study, research and application, especially the close combination between the manufacturer and the user. Because manufacturing enterprises are not familiar with user needs and process problems, most of the topics now arranged are led by users

the third is the combination of host, CNC system, cutter and other functional parts. Although there is still a certain gap in the practical application of domestic CNC systems and functional components, especially some equipment for major special research is relatively high-end, we emphasize the need to give opportunities, and each topic requires the participation of CNC systems and functional components. Only in this way can we "bring" domestic functional components

fourth, emphasize "use". The current project requires users to use at least half a year. Any development can not guarantee 100% success, so the use is very important

wangfuchang said that the "04 CNC machine tool project" has been implemented for five years. At present, a mid-term evaluation is being made to clarify the focus of the next step. He hoped that relevant enterprises would actively participate in the project and make suggestions for the implementation of the project, especially in the aerospace and other fields, and put forward suggestions on the development of relevant equipment urgently needed by the aerospace and other countries
