The first heavy-duty truck longitudinal beam roller production line was built at Dongfeng Commercial Vehicle Company's frame plant, which indicates that the Dongfeng commercial heavy-duty truck frame has reached the international advanced level.
The director of the plant, Zhou Jianguo, said that the completion and production of the heavy-duty longitudinal beam roller line has achieved three major breakthroughs:
One is the breakthrough in the quality of the frame. This roller production line has the first CNC three-sided punching machine, robotic plasma cutting machine, shot blasting machine and other equipment, and the world's first bus control, fully automated connection device, which can solve the stringer production process There are quality problems such as poor accuracy, surface scratches, offset holes, and leaks.
The second is the breakthrough in processing mode. The longitudinal beam processing mode, the traditional method is "die stamping molding", this processing mode has poor market adaptability, high production cost and long production cycle. Roller production line is to change the original "larger die press" into "rolled line plus three-faced punch". This production method not only improves the flexibility of the production line, shortens the production cycle, but also changes the line-side production environment.
The third is the breakthrough in production capacity and cost. In the past, the production of the frame and the use of die stamping molding methods could only produce 50,000 frames per year, which can now be increased to 120,000 pieces.
Zhou Jianguo said that the roll forming line brought together the most advanced equipment in the world's car frame longitudinal beam processing technology. The application of these high-end technologies and international advanced technologies has provided a broad platform for Dongfeng Commercial Vehicle Company's frame plant.
