China Motorsport: 15 times/minute: They rewritten history - Sidelights of Jinan No.2 Machine Development World's Leading Automotive Stamping Line

Nowadays, many people know that China has become the world’s largest automobile producer, but few people know that China is also the world’s largest importer of automobile production equipment. Most of the high-end CNC machine tools and basic equipment required by China's auto industry rely on imports. According to an authoritative source from the China Machine Tool & Tool Industry Association, 40% of domestic metal cutting machine tools are supplied to the automotive industry, but few can enter key areas such as engine production lines. At China's OEMs, most of the equipment required for the four major processes (press, welding, painting, and final assembly) needs to be imported.

In the four process equipment, stamping production line is the first process. Here, the situation has started to change. The Chinese machine tool industry has been swept away, elated, and qualified to compete with the world's top companies. However, this situation does not represent the overall level of industry enterprises, but rely on a leading industry leader in the industry to support. This company is Jinan Second Machine Tool Group Co., Ltd.

■ Strengthen the impact of the world's highest standards The number of Jinan No. 2 machine tools in China and the world in the field of automotive stamping equipment has two prominent figures: First, in the field of domestic automotive CNC stamping equipment, the market share of 80% of the industry; To develop and produce the most advanced fully automatic stamping production line capable of stamping 15 large-scale automotive panels per minute. “80%” laid the foundation for Jinan No. 2 Machine Tool in the domestic automotive stamping equipment manufacturing industry, and “15 times/minute” demonstrated the strength of Jinan No. 2 Machine Tool in striving to become a world-class company. This “15 times” also allowed the Chinese machine tool industry to rewrite the history of not providing the most advanced equipment for the automotive industry. According to industry sources, the production of the highest level of fast stamping lines provided by Chinese stamping companies to Chinese users is 13.5 beats per minute.

In April this year, the first "15th line" developed by Jinan No. 2 Machine Tool was put into trial production at Shanghai GM Dongyue Automobile Co. In the following months, Jinan No.2 Machine Tool Co., Ltd. successively signed more than 10 high-speed, fast-feeding stamping production lines with SAIC-GM and FAW-Volkswagen domestic car manufacturers.

The leaders of the China Machine Tool Industry Association commented on the “15th line”: “Every time it is raised, it is a terrible problem. It puts high demands on the structural strength, manufacturing precision, and control systems of the equipment. This is like a hundred. After the meters race, the grades increased from 12 seconds to 11 seconds, 10 seconds, and then to 9 seconds, which is one step ahead. The Jinan No. 2 machine tool has reached such a level. It is not easy.

On September 2nd, 2009, Jinan No.2 Machine Tool Co., Ltd. developed and produced the “12th line” for SAIC-GM-Wuling Qingdao Automobile Branch and passed the “National Science and Technology Support Plan Project” acceptance with a score of 93.9. Since the line was put into production in May 2008, it has been operating 24 hours in a row. According to the director of manufacturing of SAIC-GM-Wuling Qingdao Branch, the quality of the workpieces stamped from the “12th line” is very good and the efficiency is very high. It has set a record of 3850 pieces in a shift of 8 hours. According to Zhang Shishun, deputy general manager of Jinan No. 2 Machine Tool, "The technical leap from line 12 to line 15 is like a leap from 'train' to 'high-speed train'.

■ Including major special projects to improve the level of research and development The person in charge of the Jinan No. 2 Machine Tool believes that it is the implementation of major national special projects that has given birth to “15 lines”. On December 24, 2008, the State Council executive meeting reviewed and approved in principle the implementation plan of major science and technology projects for "high-end CNC machine tools and basic equipment." The program will upgrade the machine tool industry from general manufacturing to a national strategic industry. As one of the 16 national major science and technology projects identified in the National Medium and Long-Term Scientific and Technological Development Plan Outline (2006-2020), the first batch of "high-grade CNC machine tools and basic equipment major special projects" was formally implemented in January 2009.

The launch of major special projects provided unprecedented policy and financial support for the independent innovation of machine tool companies, as well as an up-to-date review of the strengths of the industry and enterprises. More than 300 times for the country to provide the first set of large-scale technical equipment Jinan No. 2 machine tools, has undertaken a "large-scale fast and efficient CNC automatic press production line", "NC large-scale multi-station presses," "large servo presses," " "The large-scale precision composite stamping machine tool innovation platform", "high-speed gantry five-axis machining center" and other seven major science and technology projects involving automobile, military, energy and many key industries, covering metal forming, metal cutting, innovation platform, key functions Components and other key areas. On September 20 of this year, the results of the significant major projects represented by the “15th Line” were highly praised by the leaders of the relevant national ministries and commissions.

Since the implementation of major special projects, Jinan No. 2 Machine Tool has invested 480 million yuan to improve the innovation system, overcome 35 key technical difficulties, obtained 12 national invention patents, 11 utility model patents, and formulated 5 national standards and 1 industry standard. There are 20 enterprise standards. Supported by comprehensive scientific and technological innovation, Jinan No. 2 Machine Tool Co., Ltd. has achieved simultaneous development with the latest international technology in the fields of single-arm high-speed feed lines, large multi-station presses, and large servo presses.

â–  Accelerate marketization The implementation of major special projects of powerful international suppliers has accelerated the pace of marketization of new technologies. It is reported that in the orders for forging equipment received by Jinan No. 2 Machine Tool this year, the proportion of orders for high-tech products such as multi-station presses for rapid automated stamping production lines has increased from the original 10% to nearly 50%. In the international market, Jinan No.2 Machine Tool Co., Ltd has won orders for key projects such as 2000 tons of 5,000 tons of multi-station presses, 1,000 tons of heavy-duty blanking lines, and 3,200 tons of large-scale stamping lines from customers in the United States, Australia, Brazil, India, and Thailand. It has become a global supplier of GM, Ford, Mercedes-Benz, Suzuki, Honda, Nissan and other international auto giants, and is regarded as one of the "world's three largest stamping equipment manufacturers" by foreign customers.

In fact, Jinan No. 2 Machine Tool Co., Ltd. is the only qualified Chinese company to bid for the domestic high-end stamping equipment. Jinan No.2 Machine Tool demonstrated the development and strength of China's machine tool industry in the competition with Germany and Japan and other world-class companies.
