Draw the blueprint of auto parts from the metal forming industry

In the field of automobile manufacturing, more than 60% of parts are processed by sheet metal stamping, and the forming process involves a variety of typical stamping processes. Automobile die forgings refer to the volume-formed parts, which are produced by forging process. Compared with other production processes, the mechanical properties of the parts are better. These parts are assembled in the automobile engine, suspension system, steering system, and transmission system to transmit power and Torque forgings.

Every technological advancement in the metal forming industry will arouse great attention and recognition in the field of auto parts. As an advocate of the metal forming industry, China Forging Association has always tracked the advanced technology of domestic and foreign counterparts, and formulated the future development strategy of China's metal forming industry. The future of forging manufacturing related to auto parts is slowly opening up:

First, the product design, manufacturing and application of the forging and stamping industries of auto parts in the future must be developed around the characteristics of automobile environmental protection, energy saving, safety, comfort, efficiency and convenience. With the implementation of the green development goals of reducing self-weight, energy saving and emission reduction of automobiles, the production of high-strength steel, aluminum alloy, magnesium alloy, composite materials and various hydroformed special-shaped and complex parts has gradually entered mass production, in order to adapt to these new material parts The production requires accelerated research and development and the use of new forging and stamping processes, equipment and molds.

Second, with the improvement of new stamping sheet forming technology represented by high-strength plates, high-strength steel plates are used more and more widely in the body-in-white of domestic auto companies, and the parts produced are becoming more and more complex. The application of laser tailor-welded blanks, represented by the door inner panels, is used for inner covering parts to ensure the use performance and integrity of the parts; represented by side wall reinforcement plates and longitudinal beams, they are used to improve the collision safety and safety of the whole vehicle. Lightweight level of the vehicle; Tailor welding technology is used to improve the material utilization rate of the vehicle. The finite element analysis of stamping formability provides a solution for the early analysis of the stamping process to overcome the defects in the part manufacturing process. The accuracy rate of foreign simulation technology has reached more than 95%, from forming cracking to springback analysis, reducing the workload of mold manufacturing and debugging, and effectively shortening the development cycle.

Third, in order to meet the pursuit of higher quality, greater capacity, and lower production costs in automobile production, stamping equipment will develop in the direction of large-scale, high-speed automation, precision and intelligence. It adopts a large-scale high-speed compact mechanical press production line and a multi-station press, equipped with a destacking system, an automatic transmission system, an inspection and assembly system, and a quick mold change system. The servo drive technology of the press has more in-depth applications. According to the requirements of the stamping process of different parts, the equipment can precisely control the action and pressure at different stages of the processing process, and precisely adjust the stroke curve of the slider to make the production more efficient. Better quality and longer mold life.

Fourth, some new concepts have been proposed in the field of international metal forming, such as ECOFORGE or ECOPLANT, that is, green forging or green factory. This concept is mainly to use the existing modern digital technology and experimental technology to improve heating, heat treatment, cooling, process, reduce deformation, improve product quality, so as to reduce processes, reduce consumption and emissions, and achieve the purpose of saving corporate and social costs. . We should continue to improve the existing parts, in particular, we need to actively research and improve.

Fifth, the cooperation between the upstream and downstream of the industrial chain will be deeper. Material manufacturers, automobile OEMs, forging and stamping companies will start to cooperate, starting from the development and manufacturing of parts and raw materials, structure and performance design, and the required forming processes. Make overall plans to meet the requirements of low cost and low consumption. As a component supplier, it is necessary to implement strategic cooperation with the OEM. Product development gradually transitions from the initial source map development to the function map development, and then further upgrades to synchronous development, and finally achieves professional modular development, and achieves benign interaction with the OEM. Attach importance to the professional division of labor and the strength of the team, and establish a vertical industrial strategic alliance composed of customers, forging companies, raw materials, molds and equipment suppliers.

Whether it is an automobile group or an automobile parts manufacturing company, I hope to have an industry platform to gather face-to-face understanding of leading companies in the metal forming industry, such as: Pacific Precision Forging, Wuhu Hetian Automobile Industry, Sino-German Precision Forging, Hengrun Forging , Baicheng Zhongyi, Beijing Xinguang Kaile, China 22nd Metallurgical Group, Zhaowei Electronics, Xinli Tongchuang, Cangzhou Ruier and so on. The Metal Forming Exhibition hosted by China Forging Association is just such an industry platform. There are a large number of physical displays of auto parts at the China International Metal Forming Exhibition in the Shunyi New Hall of the China International Exhibition Center from September 16 to 19, 2014. At the exhibition site, three supporting activities closely related to auto parts will be held, namely: Shengong Award High-quality Metal Forming Parts Selection, 2014 International Forgings, Stampings, Sheet Metal Parts Purchasing Conference and Forging, Stamping and Sheet Metal Production of new technology and equipment rolling conference.
