3D printing: the old area has a "technical style" - Guangzhou 3D Printing Exhibition|

In the midsummer season, when you walk into Lvliangxing County, you can see green eyes and a red scent. From "revolutionary ideals higher than the sky" to "dare to teach the sun and the moon to change the sky", today, this baptized red hot land is becoming a thriving industrial highland and a paradise for innovation between the steel frame and the splash of welding flowers. .


Starting from the county seat, travel west for half an hour and arrive at the Aluminum and Magnesium Industrial Park of Xingxian Economic and Technological Development Zone. Between the open valleys, construction vehicles shuttle back and forth, and mixers and cranes keep running. In the built-up area, machines are flying around in the workshop, and workers are focused on their work. "This is an aerospace product part? I thought it was a work of art." In the aerospace new material intelligent manufacturing center, a technician is introducing to the visitor.


In the workshop, each piece of equipment is neatly arranged, and almost no noise can be heard. The 3D printing device with a laser emitter reciprocates on a fixed track. With the flexible operation of the robotic arm and the squeak of the printing nozzle, the procedures of slicing the model, building the base, and adding powder are completed in one go, a 3D printed aerospace-grade product The mold is born in the particles of "a plate of loose sand".


3D printing, that is, additive manufacturing technology, is one of the most promising manufacturing technologies at present, and is considered to be an important production tool for a new round of technological revolution. Different from traditional manufacturing methods, 3D printing, with its "pervasive" possibility, not only brings huge imagination space to production technology, but also gives a promising future to the old revolutionary area of ​​Xingxian County, which has already won the battle against poverty.


Xing County is the largest county in our province. It has proven 23 kinds of mineral resources such as coal, coalbed methane, bauxite and dolomite. The quality of aluminum and magnesium resources is good, the mining conditions are superior, and it has unique industrial advantages. However, the single industry for a long time not only restricts the comprehensive utilization of mineral resources, but also restricts the transformation and upgrading of industrialization. In recent years, Xingxian has broken through the stereotype of thinking, changed the "one coal dominance", focused on building emerging industrial clusters, and created a new highland for the aluminum and magnesium industry.


Planting a plane tree will attract a phoenix. In May 2021, Hangyu New Materials Intelligent Manufacturing Research Institute (Shanxi) Co., Ltd. settled in the industrial park, relying on the resource advantages of Xingxian County, taking root downwards and blossoming upwards.


"The traditional manufacturing method is to use the removal processing method to remove the unwanted parts based on the raw materials, such as woodworking with a planer to process wood. The additive manufacturing technology represented by 3D printing is to use a computer during the construction process. Scan or directly create a three-dimensional design drawing, decompose layer by layer through related technologies, and gradually accumulate materials to 'stack', and finally form the required items." Yue Qian, the head of the company, explained 3D printing, she said that this kind of step-by-step process The characteristics of layered accumulation mean that there is no waste in the whole process of production, the design is freer, the process flow and design cycle are shorter, and it fully meets the needs of personalized customization.


As small as a mobile phone bracket and animal model, as large as a huge car and space shuttle parts, in the exhibition hall of the Aerospace New Materials Intelligent Manufacturing Center, there are various 3D printing figures in different fields. "We take the initiative to empower the industry with 3D printing technology, focusing on the implementation of 3D printing industrialization demonstration applications, and speeding up the integration of 3D printing and the military industry." Yue Qian said that combined with the market demand for lightweight military products such as aerospace, aerospace uses advanced Arc wire feeding additive manufacturing technology and laser selective melting additive manufacturing technology are used to produce military products in aerospace and other fields.


A piece of A4 paper-sized missile tail rudder surface is exquisitely designed and irregular. The staff picked up a cut part, and its internal three-dimensional mesh structure is amazing. The thin-walled cavity mechanism and the internal lattice support are its technical difficulties. Using traditional processes such as "turning, milling, planing and grinding" requires at least 20 parts, and the production and processing cycle is long. Today, Aerospace uses 3D printing technology to import 3D modeling into a 3D printer for direct molding, reducing the number of complex parts to 1, greatly shortening the manufacturing time, allowing the aircraft to “slim down, lose weight, and travel lightly.”


"Relying on the industrial Internet, we have achieved collaborative design on the cloud and intelligent manufacturing off the cloud." Yue Qian said that the additive manufacturing Internet platform integrates the Internet of Things, big data, cloud computing and artificial intelligence and other information technology and 3D printing technology. The integration has opened up the "information island" in various business links such as user needs, R&D design, and manufacturing. In the development plan of Aerospace, firmly grasp the pulse of the times, take the step of "Internet + Additive Manufacturing", rely on the Internet to realize remote collaborative manufacturing, and provide more possibilities for cross-industry and cross-domain 3D printing products.


The rapid introduction of equipment and the realization of engineering applications, from theory to practice, Aerospace has made great efforts to achieve more and more technological incubation results. In order to achieve full use of Jin materials, Hangyu relies on the rich mineral resources of Xingxian County, and plans the layout of aluminum alloy precision machining from the perspective of industrial chain development. It is used as 3D printing raw materials for satellites, rockets, missiles and other product parts in the aerospace field, and opens up the upstream, midstream and downstream links of industrial development.


Confidence in aerospace development comes from an excellent business environment. In 2021, Xingxian Economic and Technological Development Zone will make every effort to introduce and promote the project construction. Under the multi-element comprehensive services such as "commitment system + standard land + full agency", it took only 4 months to build 5,000 square meters for the project. The high-standard workshop helps 3D additive printing intelligent manufacturing machines and equipment enter the site, complete assembly and debugging, and reach production conditions.


It is time for deep cultivation of old areas. "Those who are interested are not far from mountains and seas. Shanxi's business environment has accelerated for corporate investment and upgrading. We can enter, enter fast, retain and develop well." Yue Qian said that in the future, Aerospace will Give full play to the technical advantages in the field of aerospace additive manufacturing, strive for excellence in the production process, extensively contact upstream and downstream partners, scientific research institutions, and expert teams in the industry, introduce more torches and sparks, and promote the development of the entire intelligent manufacturing industry cluster, Sow the seeds of technology and innovation in this red hot land.
