"Yawei Corporation Awarded the Second Prize for Technological Advancement in the 2021 China Machinery Industry Science and Technology Awards

Recently, the China Machinery Industry Federation and the Chinese Society of Mechanical Engineering jointly announced the list of winners for the '2021 China Machinery Industry Science and Technology Awards.' The project titled 'High-Flexibility, High-Performance Sheet Metal Bending Unit' led by Yawei Corporation has been awarded the second prize for technological advancement.

The 'China Machinery Industry Science and Technology Award' was jointly established by the China Machinery Industry Federation and the Chinese Society of Mechanical Engineering, approved by the Ministry of Science and Technology of China and certified by the Office of National Science and Technology Awards. It is a comprehensive award aimed at the entire national machinery industry.

Yawei Corporation took on the development of sheet metal bending machines in the early 1990s. Faced with the urgency of demand, the gap in the supply side, and the trend of frontier development, the company undertook the responsibility of developing high-end domestically produced sheet metal bending machines. This project's products were driven by the downstream industries' needs for flexible, efficient, and high-quality processing. They benchmarked international leading high-performance technology for sheet metal bending machines, introduced a new method of trajectory forming processing, developed proprietary automatic programming CAM software, and universal die technology. Key technologies were invented, such as the high-dynamic seven-link bending mechanism and the multi-axis multi-channel collaborative bending machine control system. A high-flexibility bending unit was developed to solve the bottleneck problem of low bending efficiency in the sheet metal processing technology chain. Mechanisms for automatic angle compensation and control were proposed, addressing the industry's challenges of long angle correction times and material waste. The process mechanism for scratch-free sheet surfaces was provided, solving the industry's problems with the current process mode not meeting the high-end sheet surface quality protection requirements for applications like coating, mirrors, and fingerprint resistance.
 

The research on high-flexibility and high-performance multi-sided bending technology and equipment led to breakthroughs in a range of foundational application technologies, driving the development of the industry of sheet metal processing equipment as well as related industries such as upstream control, software, servo systems, and molds. Trajectory forming processes broke free from the constraints of mold shapes, while automatic angle compensation technology, driven by intelligent solutions, changed the process mode from 'trial-and-error' to 'bending first,' achieving a major innovation in the industry's process principles. Scratch-free sheet surface processes changed the use of films and media, enhancing the industry's application process level. A series of significant achievements were made in automatic programming software, control technology, and mechatronics integrated design, resulting in high-quality intellectual property rights and the gradual establishment of a multidisciplinary integrated enterprise innovation research platform. This has played a significant role in demonstrating independent innovation within the industry, enhancing its competitiveness in terms of high-level technological quality against international advanced enterprises.

Additionally, the company's participation in the project 'Key Technologies and Applications of High-Torque, Low-Pulsation Direct-Drive Permanent Magnet Motors' also received the second prize for technological advancement. The project 'Key Technologies and Applications of Lightweight, Low-Pulsation Direct-Drive Permanent Magnet Motors' received the first prize in the Electrical Primary Group of the 2021 China Electric Power Science and Technology Progress Awards."
