China's heavy-duty trucks, which pursued development through independent innovation, witnessed new breakthroughs. The HOWO-A7 welding line with milestones in the development of domestic heavy-duty trucks was recently put into production at the truck-stock bodywork factory and quickly adapted to the five models of HOWO-A7. The multi-variety, fast-paced, high-quality mixed-flow production needs of the cab, the production design beat less than 4.5 minutes, and the high-quality positioning was successfully achieved. As one of the important links in the National 863 Program "Heavy-duty Vehicle Integrated Development Technology", the HOWO-A7 welding line provides a solid foundation for building high-quality car bodies. The entire welding line was designed and manufactured by an international gold medal team who had experience in cooperation with Sinotruk and successfully developed the HOWO body welding line. It integrates the well-known German company's intelligent automation integration technology and adopts advanced advanced imported precision equipment. , Fully guarantee the reliability of the body production, cast the excellent quality of the HOWO-A7 international heavy truck. In order to ensure the consistent production of various types of models with different lengths and heights on the basis of the HOWO-A7 model, the new welding line of China National Heavy Duty Truck adopts flexible design in transmission devices and fixture structures, and realizes flexibility of different models through electrical control. Production can be quickly converted and adjusted according to the on-line models. High-speed, high-efficiency and automated welding methods are the places of interest for this welding line. China National Heavy Duty Truck selects several Swedish ABB welding robots for the new welding line, which are responsible for spot welding, riveting, gluing, handling, edging, etc. task. Complementing this is that the HOWO-A7 welding line uses digital manufacturing control technology throughout. The overall system is open and modular, integrating the microcomputer control system, control cabinet, programmable teach pendant drive operating system and embedded PLC The function provides a high degree of convenience for the design of the main line of robotic applications. The center of the HOWO-A7 welding line, the main line, adopts an advanced lifting and stepping type transmission mechanism, and has outstanding features such as simple and reasonable structure, good stability, short auxiliary time, high repetitive positioning accuracy, and high flexibility in automation. . The HOWO-A7 welding line has two distinctive features that effectively ensure the dimensional accuracy and stable welding quality of the HOWO-A7 cab assembly. In the door assembly production line, China National Heavy Duty Truck will use the advanced production technology of the car wheel rims first for heavy truck applications, and the robot door edging system “automatically on-line—automatic recognition of models—automatic gluing, wrapping†has improved. Door assembly edging quality and production efficiency. The riveting automation system is another highlight of this welding line. Advanced robotic riveting technology effectively increases the torsional strength of the car body. The official production of the HOWO-A7 welding line of China National Heavy Duty Truck Group achieved the orderly control of the auto body stamping, welding and painting processes. The design of the series of general-purpose station appliances was realized while using multiple measures to ensure the appearance quality. Production has also been fully in place to ensure that the HOWO-A7 multi-variety body is unobstructed in mixed-flow production.
