Digital intelligence will become the core of manufacturing

On the morning of September 8, the 14th China Association of Science and Technology Annual Conference held an opening ceremony in Hebei Hall, Shijiazhuang, Hebei Province. After the opening ceremony was the special report stage for the conference, Academician Zhou Ji of the Chinese Academy of Engineering made a report titled "Digital Intelligence in Manufacturing Industry" and proposed that the digitization and intelligence of the manufacturing industry is the core of the new industrial revolution, relying on technological innovation to achieve From the "manufacturing power" to "manufacturing power" a historic leap.

“The connotation of advanced manufacturing technology innovation includes three aspects: product innovation, manufacturing technology innovation, and industrial model innovation. Digital and intelligent technologies are common enabling technologies for product innovation and manufacturing technology innovation, and profoundly reform the production mode of manufacturing industry. The industrial form is the core technology of the new industrial revolution.” Zhou Ji said that the extreme importance of product innovation can be seen from two cases. Digital cameras are examples of the application of digital technology to the innovation of traditional products. Kodak, which used to be a global monopoly in the film industry, developed the world’s first digital camera in 1975. However, due to strategic mistakes, it did not market this technological innovation. As the traditional film industry was overturned by digital technology, Kodak finally declared bankruptcy this year.

The traditional mechanical product composition includes three parts: power device, transmission device and working device. Its innovation can have many ways. There are mainly two methods. One is the innovative working principle or working device, and the other is the driving and controlling system of innovative sports. The first kind of innovation is the principle of work innovation, which is fundamental and extremely important. The three-dimensional printing technology just mentioned belongs to this type of innovation. For thousands of years, people have been continuously creating new machines and forming thousands of mechanical products suitable for accomplishing different tasks. NC is the innovation of the drive and control of mechanical movement. It is the second innovation and an effective way to innovate mechanical products. Its core technical line is, on the one hand, the use of digital motor drive system to replace the traditional mechanical power devices. On the other hand, it is also more important to use a computer control system to control the mechanical properties and working process, that is, to put a brain on the machine. CNC technology is a subversive universal enabling technology that enables mechanical product innovation. The core is digital. The application of numerical control technology has fundamentally changed the connotation of mechanical products, greatly enriched the functions of the products, qualitatively changed the performance, fundamentally improved the product level and market competitiveness, and made mechanical products develop intelligently.

"Speaking of CNC, people think of CNC machine tools. This is right, but it is not comprehensive. CNC machine tools are examples of innovative CNC products, but CNC technology is a universal enabling technology that can be applied to all kinds of Mechanical products are undergoing innovation and upgrading.” Zhou Ji said that injection molding is the most effective plastic molding method, such as the numerical control and intelligentization of injection molding machines. China is the world's largest producer of injection molding machines and its output accounts for more than 70% of the world's annual production capacity. However, in terms of high-end products, it lags far behind the world's advanced level. Injection molding machine to complete the mold opening and closing, injection, plasticization, mold release, mold adjustment, injection table movement and other six actions, respectively, by the six implementing agencies to achieve. The development of injection molding machines has experienced the evolution from traditional hydraulic type to servo energy-saving type to all-electric type. The traditional hydraulic injection molding machine is powered by ordinary motors, and the hydraulic traditional system drives six actuators. The servo energy-saving injection molding machine skillfully applies digital technology. The AC servo motor replaces the original ordinary motor, and the hydraulic transmission technology remains unchanged. This innovation can realize the on-demand supply of energy, and the power consumption can be reduced by 40%-80%. All-electric numerical control injection molding machines can now be driven by servo motors and controlled by computer numerical control systems. Its advantages are high processing accuracy and stability, good quality, high production efficiency, low noise, and no pollution. The intelligent numerical control injection molding machine is a further introduction of intelligent technology, to achieve automatic optimization of the process, automatic compensation of parameters, automatic sorting of products, automatic monitoring of processes and automatic diagnosis of faults, to achieve higher efficiency, higher accuracy and better The energy-saving effect.

“Comrades in the Chinese manufacturing industry have a common goal. By the year 2020, China’s machinery products will be fully equipped with CNC technology. The overall upgrade will be the CNC generation. The Chinese manufacturing industry will basically popularize digital technologies and achieve a certain degree of intelligence in a number of years. By 2030, China's machinery products will be upgraded to an intelligent generation, and China's manufacturing industry will adopt the smart manufacturing model in its main areas, and it will take the lead in the world as a whole. Our goals must be achieved and our goals will be achieved."
