The manufacturing technology of the most popular d

The manufacturing technology of domestic key stamping equipment has reached the international advanced level

on May 18, the high-end CNC machine tools and basic manufacturing equipment undertaken by Jinan No.2 Machine Tool Group Co., Ltd. (hereinafter referred to as Jinan No.2 Machine Tool) were given priority to start the major scientific and technological special large-scale fast and efficient CNC automatic stamping production line and CNC large-scale multi station press, which passed the national acceptance at the same time in Yantai. These two projects are the key high-end stamping equipment urgently needed by the automotive industry. Their stable and reliable operation and acceptance in users mark that the manufacturing technology level of stamping equipment in China can be comparable with that of world-class enterprises. Among them, the large-scale fast and efficient CNC automatic stamping production line is one of the ten key demonstration projects of national major projects

the acceptance meeting was organized by the Ministry of industry and information technology, and an acceptance expert group headed by Yu Chengting, honorary president of the China Machine Tool Association, was established. More than 50 experts and users from the Ministry of industry and information technology, the Ministry of science and technology, the China Machinery Industry Federation, scientific research institutes in related fields, and the automotive industry attended the acceptance meeting. Wang Fuchang, deputy director of the equipment industry department of the Ministry of industry and information technology The deputy inspector of the development planning department of the Ministry of science and technology can choose Liu Yulan to attend the acceptance meeting and speak according to the specific experiment

during the acceptance meeting, the expert group listened to the work report of the research group, reviewed the relevant acceptance data, and conducted on-site tests at SAIC General Motors Yantai Dongyue company and Shandong Jiezhong company respectively. This kind of method will usher in a new era of flexible electronic technology. After inquiry and discussion, both projects passed the acceptance unanimously

stamping 15 large auto panels per minute

large fast and efficient CNC automatic stamping production line is mainly used for the production of large auto panels. Relying on the 64000kn single arm feeding and stamping production line provided for Chery Automobile Company and the 42000kn double arm feeding and stamping production line provided for SAIC general Yantai Dongyue company, Jinan No.2 machine tool has carried out the research on the large-scale fast and efficient NC fully automatic stamping production line in an all-round and multi angle way, mastered 11 key core technologies and integrated manufacturing technologies of the large-scale panel high-speed forming and stamping production line, and withstood the high-volume Through the test of high-efficiency continuous production, the product technology has reached the international advanced level of similar products, and some performance indicators are better than those of similar products of enterprises in the same industry in Germany and Japan

the 42000kn double arm feeding stamping production line provided for SAIC General Motors Yantai Dongyue company can punch 15 large auto panels per minute, creating a new record for large auto panel stamping production, and the die change speed is fast, which meets the needs of multi model and multi part co production. It is the highest level auto stamping production line used in China at present. Since it was officially put into use in March 2010, the daily production capacity has reached more than 10000 pieces, which has played a key role in achieving the production target of 1 million vehicles of SAIC general Dongyue company. This stamping line is also the highest level heavy stamping production line used by domestic automobile enterprises at present. Its main technical performance indicators are better than foreign products, showing the development and progress of China's equipment manufacturing industry

Wang Fuchang spoke highly of the successful implementation of the large-scale fast and efficient CNC automatic stamping production line project. He said: in the whole domestic equipment manufacturing industry, there are not many that can match the advanced level of foreign countries. The successful development of this line has played an important role in the automotive industry. Whether it is to improve production efficiency or product level, and reduce the production cost of sports and leisure products, the role is very prominent, and it has also played a good leading role in the structural adjustment of our country's equipment manufacturing industry

energy-saving and efficient large multi station press

large multi station press is mainly used for the production of large quantities of interior and exterior decorative stamping parts. As a pacesetter in the forging industry, Ji'er is the first enterprise in China to master the technology of large multi station press and promote products to domestic and foreign markets. Previously, the first generation of 2000t, 2500t and 5000t large multi position press developed by Jinan No.2 machine tool was exported to the United States, Mexico and Australia

in the project of large-scale multi position press undertaken this time, on the basis of summarizing the previous development and manufacturing experience, two 25000kN large-scale multi position presses and their supporting equipment have been developed, and the parametric design of multi connecting rod, the design of anti eccentric load high-strength gear transmission mechanism, the force analysis of solid modeling, full-automatic mold change, the failure and analysis of heavy-duty machinery, remote communication and remote monitoring It can realize the research and verification of 12 key technologies, such as data transmission, mold interference analysis, three coordinate servo feeding and host synchronous motion control. It integrates mechanical, electronic, control and detection technologies, and can realize the high-speed, high-precision, fully automatic production of stamping parts. The production efficiency is increased by 3-4 times, the energy saving is more than 50%, the production area is saved by more than 40%, and the comprehensive investment cost is significantly reduced

with the rapid development of the domestic automotive industry, the demand for large-scale fast and efficient CNC automatic stamping production lines and large-scale multi station presses is growing rapidly. Since 2009, Ji'er has undertaken more than 20 orders for large-scale rapid and automatic stamping production lines. At present, the six domestic CNC large multi position press production lines used in the domestic market are all from Ji'er. Domestic high-end stamping equipment has been industrialized. As a leading enterprise in the forging industry, Jinan No.2 Machine Tool Co., Ltd. is also the only Chinese enterprise with international bidding qualification in this field

major special projects have achieved fruitful results

it is reported that during the implementation of the two projects of large-scale fast and efficient automatic stamping production line and CNC large multi station press, Jinan No.2 machine tool has invested a total of 440million yuan in technical testing, equipment and instrument purchase, scientific research facilities construction, etc., and established a research group headed by the leaders of the group company, organized and invested R & D personnel to overcome the double arm rapid feeding system More than 30 new technologies, such as multi link parametric design, servo feeding mechanism design, servo feeding and host synchronous motion control

with the implementation of major projects, Jinan No.2 machine tool has also made a series of important achievements in patent application and standardization. Relying on major special projects, we applied for 7 national invention patents, 11 utility model patents, and formulated 2 national standards, 1 industry standard, and 3 enterprise standards
