The commissioning of the first set of intelligent sheet metal flexible bending center developed by the Science and Technology Application Design Institute of Guangzhou Shipbuilding International Technology Center (Marine Science and Technology Research Institute) under the China Shipbuilding Group and Guangzhou Shipbuilding International Elevator Electromechanical Equipment Co., Ltd.
1、 Introduction to intelligent sheet metal flexible bending center:
The intelligent sheet metal flexible bending center is equivalent to a "printer" that can print various specifications of sheet metal boxes and other products. This sheet metal product is widely used in the sheet metal manufacturing industry such as electrical cabinets, kitchen utensils, furniture, elevators and so on.
The intelligent sheet metal flexible bending center is a revolution to the traditional pressure bending machine. It subverts the rigid linear movement of the traditional bending machine mold, and the bending times are not limited. The mechanical sucker device drives the front and back movement and rotation of the plate, which can carry out multilateral bending. The whole process is controlled by the system automation, which can effectively and conveniently realize unmanned operation and production. During the bending process, the plate can be bent forward and backward without the help of auxiliary tools or manipulators, and the production efficiency can be doubled.
Taking the intelligent sheet metal flexible bending center developed by Guangzhou Shipbuilding International as an example, it takes only 5 seconds to fold a knife, and 8 knives to fold a double-door refrigerator cabinet table panel, and only 40 seconds to complete the whole process. If it is manually operated, a skilled master can also take at least 10 minutes to complete, with obvious efficiency advantages.
2、 Market situation of bending machine at home and abroad:
The earliest foreign enterprise to produce bending centers is Italy's Savanini Company, which produced the world's first set of bending centers as early as the end of the 1970s, but its price is very expensive, and one set costs millions or even tens of millions of yuan, which makes many Chinese enterprises wait and step back. With the rising labor costs in recent years and in order to meet the needs of enterprises for improving product quality and efficiency, in recent years, the demand of some domestic manufacturing enterprises for intelligent sheet metal bending centers has gradually increased. In order to meet the market demand, many domestic machine tool manufacturers have started research and development in this area, but there are still no very mature products to launch on the market.

R&D team of intelligent sheet metal flexible bending center:

The R&D team of the first intelligent sheet metal flexible bending center led by Sheng Shaoqin and Zhao Gang
Guangzhou Shipbuilding International Elevator Electromechanical Equipment Co., Ltd. has followed the deep foundation of "Guangzhou Shipbuilding Machinery", and on the basis of nearly 40 years of deep cultivation of the shear press market, launched the research and development of the intelligent sheet metal flexible bending center in June this year, and established a research and development team led by Sheng Shaoqin, the director of the Institute of Science and Technology Application Design, and Zhao Gang, the deputy director of the Institute, to study the equipment. After extensive research and concentrated research by the research and development team, the first set of bending center with independent intellectual property rights has been successfully developed, and the sales price is expected to be less than one-third of the imported equipment.
Sheng Shaoqin said that Guangzhou Shipbuilding International could provide customers with intelligent sheet metal flexible bending center to meet their needs based on customers' needs and in combination with nearly 40 years of bending technology and equipment product development experience, which would greatly improve production efficiency and product quality for customers.
3、 Master core technology and own independent intellectual property rights
The road to success has never been achieved overnight. The successful research and development of the first set of intelligent sheet metal flexible bending center is just another accumulation of Guangzhou Shipbuilding International in the field of machinery manufacturing. In the final analysis, the intelligent bending center is to add an automatic control system to the traditional bending machine, and its core is still in the mechanical manufacturing.

The "tools of making utensils" have always been the place where foreign enterprises make necks in China, which are either expensive or not sold to us at all.  
The successful research and development of the intelligent sheet metal flexible bending center with completely independent intellectual property rights may only be a small step for sheet metal processing machinery, but I believe that there are many such small steps, and a big step will be taken to strengthen the manufacturing in China.
4、 Guangzhou Shipbuilding Machinery Co., Ltd. has profound mechanical skills and is well known
Sheng Shaoqin said in an interview that the key to the successful development of the first set of intelligent sheet metal flexible bending center lies in the strong technical foundation of Guangzhou Shipbuilding Machinery Manufacturing. Indeed, as a large backbone shipbuilding enterprise of China Shipbuilding Group in South China, most people only know its achievements in the field of marine equipment construction, but in fact, the brand of "GSI" is also well-known, especially in the field of sheet metal processing machinery, which has been intensively cultivated for nearly 40 years, and has created countless brilliant achievements in the fields of shear press and automatic production line.
5、 An enduring brand of shear press

The sales volume of Guangzhou Shipbuilding International Shearing Press is increasing year by year, which is the "hard currency" of the sheet metal industry
Hydraulic bending machine and hydraulic pressure reducing bed, referred to as "shear press" for short, are the pillar products of Guangzhou Shipbuilding Machinery, which were developed in the 1980s and have completed many technical upgrading iterations. The shear press produced by Guangzhou Shipbuilding International has won wide acclaim in the market for its durable and excellent performance, and has always been the "hard currency" of the sheet metal processing industry. It is understood that the second mobile phone of the Guangzhou Shipbuilding International Shearing Machine, which has been used for 10 or 20 years, may be more expensive than the new machine of some brands, which fully demonstrates that the Guangzhou Shipbuilding International Shearing Machine has reliable performance and is easy to use.
6、 Develop the first refrigerator production line in China
In 1992, when Guangzhou Hualing Refrigerator Factory was developing a new type of refrigerator in China, it encountered the problem that the circular arc forming of the color plastic panel door was not qualified and the qualification rate was low, while the cost of the imported foreign refrigerator production line was very expensive. After that, it was connected by people and found the original machinery business department of Guangzhou Shipbuilding International to carry out the research and development. In the absence of any domestic production line of the same type, the R&D team of Guangzhou Shipbuilding International successfully produced the first domestic full-automatic refrigerator production line in 8 months, and trial-produced it in Hualing. The production efficiency of this production line is not only twice as high as that of similar imported equipment, but also covers only one third of the area of similar equipment produced in Germany.

In the 1990s, Haier refrigerator production line developed by Guangzhou Shipbuilding International
Later, in addition to Hualing, the first-line refrigerator brands in the market at that time, such as Kelon, Haier, Sino-Italian, Electrolux, Huari, Xiliang, Shuanglu and Bole, all adopted this production line. The market share of the refrigerator production line of Guangzhou Shipbuilding International reached 80%, completely replacing imports. After that, Guangzhou Shipbuilding International Machinery Business Department has successively developed a series of products for Kelon, Haier and Hualing, such as side plate roll binding line, box foaming line, door foaming line, etc., which has led to the popularity of Guangzhou Shipbuilding International in the field of refrigerator production line. However, due to the small market capacity of the product, the production was gradually stopped.
7、 Development of Boeing hydrofoil and column engineering
The hydrofoil and column were originally the key components of the jet hydrofoil ship, a patented product of Boeing Company of the United States, and the quality requirements were extremely strict. In 1985, Hong Kong Far East Hydrofoil Ship Company wanted to replace the hydrofoil of the hydrofoil ship purchased by it from Boeing. With the permission of Boeing, it decided to transfer the hydrofoil to domestic production, and the former International Machinery Business Department of Guangzhou Shipbuilding Co., Ltd. undertook the research and development task.

Hydrofoil developed by Guangzhou Shipbuilding International Machinery Team
In the absence of ready-made equipment, the team of Guangzhou Shipbuilding International Machinery Business Department specially developed a three-axis profiling milling machine for the hydrofoil, which perfectly processed the hydrofoil column that can only be processed by CNC gantry milling, which surprised Chinese and foreign experts. At that time, the production of this milling machine only cost 160000 yuan, and 8 sets of high-quality hydrofoil were processed before and after, with a profit tax of more than 10 million yuan.
In addition, the Guangzhou Shipbuilding International Machinery Business Department also made the "Guangdong" float for review in Tiananmen to celebrate the 50th anniversary of the founding of the People's Republic of China, and designed and produced the 34-ton classic works for the Ninth National Games, such as the China Century Monument, which is still popular with many Guangzhou Shipbuilding people. In recent years, relevant teams have jointly designed and produced the shock absorption system of Guangzhou Tower, a landmark building in Guangzhou, in cooperation with Guangzhou University, filling the technical gap in this field.

Today, the backbone personnel of the Science and Technology Application Design Institute of Guangzhou Shipbuilding International Technology Center (Marine Research Institute) and Guangzhou Shipbuilding International Elevator Electromechanical Equipment Co., Ltd. are the heirs of Guangzhou Shipbuilding International Machinery Business Department. They have always adhered to the original intention of making China stronger, worked intensively in the market segments, and continue to write the new legend of Guangzhou Shipbuilding International in the field of machinery manufacturing.
