Donghai Machine Tool Extra Large Bending Machine Developed Successfully

Under the guidance of experts from the National Institute of Foundry and Forging Press, the large-scale three-machine linkage NC bending machine independently developed by Nantong Donghai Machine Tool Manufacturing Co., Ltd. has been successfully tested. The maximum nominal pressure of the model bending machine is 4000 tons, and the length of the foldable sheet material is 18 meters.

According to reports, the maximum nominal pressure of bending machines produced in Asia before was only 2,000 tons. China's forging machinery enterprises can only produce bending machines with a maximum nominal pressure of 600 tons; and Nantong Donghai Machine Tool Manufacturing Co., Ltd. successfully developed 4000 tons of 18 The three-machine linkage CNC bending machine is not only the first in China, but also refreshes the Asian record. This oversized CNC bending machine will be widely used in the manufacture of automobiles, trains, elevator components and wind power towers. The market prospect is very broad.

Libao Town is known as the “Hometown of Chinese Scissors Rolls” and has more than 130 enterprises specializing in the production of forging machinery. Currently, it is forming a high-tech industrial cluster and has developed 10 new products to fill the domestic gap. With an annual output value of 10 billion yuan, the products are exported to more than 10 countries and regions such as the United States and Germany. Nantong Donghai Machine Tool Manufacturing Co., Ltd. is one of the leading enterprises in the town's shear folding machine tool industry. Over the years, it has always adhered to the road of technological innovation, constantly developing new products, and actively expanding domestic and foreign markets. In recent years, the company’s output value has been 35%. The astonishing increase in increments. This time the development of an extra-large bending machine, the company focused on more than 30 technical staff, took more than 4 months, drawing only more than 10,000 drawings, to achieve all components, including hydraulic system and numerical control device independent design. Chen Baoyin, chairman of the company, said that the company will continue to sprint high-end shear roll machines and begin development of a 6,000-ton extra-large CNC bending machine.
