Foundry is the basic industry of the equipment manufacturing industry. When it comes to casting, the first thing people think of is the “silly big black rough” appearance of traditional foundry products, and the 3D printing green intelligent foundry of Jiugang Group Western Heavy Industry Co., Ltd. has been put into use in China. The largest sand mold 3D printing equipment has broken the inherent image of the industry and turned the foundry industry into a “fair lady”, opening a new era of intelligent manufacturing and accelerating the pace of transformation and development of “green intelligence”.
Walking into the 3D printing intelligent foundry of Jiugang Group Western Heavy Industry Co., Ltd., you can’t see people coming and going, but only see the 3D printer running in an orderly manner. In this “small house”, based on computer data modeling, parameter import, After printing and sand laying, after dozens of hours of unmanned operation, the required sand mold is formed.
Jiugang Western Heavy Industry Co., Ltd. Precision Casting Branch, Secretary of the Party Branch, and Director Su Wen: The inkjet printer in the office is to spray black ink on white paper to form the documents we want. The working method of this printer is equivalent to spraying on sand. The corresponding hardening potion forms different patterns, and after 3,000 accumulations, a three-dimensional entity is formed, which is the sand mold we want.
Before a 3D printer can form a sand mold, an engineer needs to design the corresponding product into a three-dimensional digital model. In the past, a casting was needed, and the wooden mold had to be made by hand, which was time-consuming and low in accuracy. Now, the 3D printer prints the sand core according to the parameters designed by CAD, and it can be completed by pouring molten iron or molten steel, which greatly shortens the time and saves money. cost.
Pei Ruijie, Associate Engineer, Precision Casting Branch of Jiugang Western Heavy Industry Co., Ltd.: Design its corresponding 3D model according to the customer’s drawings, design its appropriate casting process according to the product’s structural characteristics and performance requirements, and input it into the 3D printer. Produce a suitable model.
Compared with the “silly big black rough” of traditional casting, 3D printing technology has turned the foundry industry into a “pretty lady”. It does not require any special auxiliary tools and is not limited by the batch size. It can quickly transform directly from a CAD 3D model to a 3D solid model. It can not only replace traditional wooden molds and metal molds to achieve moldless molding, but also has high precision and high detail. , the advantages of green environmental protection, has become an important scientific and technological force to help the transformation and upgrading of the foundry industry.
Bai Yang, Deputy Director of the Precision Casting Branch of Jiugang Western Heavy Industry Co., Ltd.: The advantages of 3D printing casting technology are: first, high production accuracy; second, high flexibility and flexibility in process design; third The production cycle is short, and the fourth is the high degree of digital intelligence.
As WHI’s 3D printing “business card” is getting louder and louder, many scientific research institutes and well-known enterprises have come to contact. At present, WHI has signed supply contracts with users for high-precision precision casting products. Subsequent products will be more used in nuclear power, hydropower, electric power, automobile manufacturing and other industries.
Jia Hongming, business manager of the Metallurgical Equipment Marketing Department of Jiugang Western Heavy Industry Co., Ltd.: At present, the production orders for 3D printing are about 6 million, and the market areas of the products are in Sichuan, Henan, Shaanxi, Ningxia and other places.
The traditional industry “has middle-aged and new”, “high-precision and cutting-edge new” is becoming a new solution. By adjusting the industrial structure, optimizing the industrial layout, accelerating scientific and technological innovation, and insisting on cultivating and developing emerging industries, the traditional manufacturing industry has achieved a transformation from “silly, black and crude” to “high-tech and advanced”, with higher quality, better efficiency and better structure. The road to better casting is also getting more and more stable.
