Advanced technology and production and testing equipment play an important role in ensuring the feasibility and stability of the forging process, and improving the quality and stability of forgings, especially high-speed and heavy-duty gear forgings. Luo Baihui, secretary general of the International Mould Association, said that my country has a complete set of advanced production equipment from forging, heat treatment, machining to flaw detection, including a program-controlled temperature-controlled natural gas heating furnace with independent intellectual property rights, and an ultrasonic C-scan flaw detector. And other equipment are at the international leading level.
　　 High-speed and heavy-duty gear forgings are the key and basic parts of transmission equipment. Their stress conditions are complex and working conditions are special. Therefore, they must have excellent working performance to ensure long-term, efficient, safe and stable operation of gear transmission equipment. The performance, quality and stability of high-speed and heavy-duty gear forgings are closely related to the forging process. According to Luo Baihui, secretary general of the International Mould Association, in terms of patented technology, my country's Jiangsu Jinyuan has 3 invention patents such as multi-point temperature sensing and intelligent control methods for gas heating furnaces and detachable molds for rounding shaft forgings8 A utility model patent, gas heating furnace temperature uniformity control technology, precision forging technology, successive control deformation technology, warm forming structure performance control technology, ultrasonic C-scan automatic detection technology for forging defects, 5 proprietary technologies, and exclusive license Use 1 invention patent.

It is reported that Jiangsu Jinyuan has long focused on the R&D, production and sales of high-speed and heavy-duty gear forgings. It has accumulated rich experience in process control in the production and operation process, gathered and trained a large number of professional and technical personnel, and formed a series of proprietary technologies. .

Jinyuan Forging currently has an annual output of 60,000 tons of forgings. Its products are widely used in equipment manufacturing industries such as electric power, motor cars, ships, metallurgy, port machinery, and heavy machinery. It has covered more than 20 provinces and cities across the country, and some products are exported to the Netherlands, Canada, the United States, India, Japan, Spain, Germany and other international markets. The product has stable quality and high reliability, and has been praised by users at home and abroad. It has been awarded the honorary titles of excellent supplier and best supplier by customers many times.

　　In the modern forging process, for the shaft forgings, the shaft forgings are generally rounded and rough processed by the plastic mold (throwing). Rounding is to realize the shaping of the circular cross-section of shaft forgings. The existing molds used for rounding are likely to cause mold damage or material loss. In addition, the flexibility of the mold is not enough. Once damaged, the entirety must be disassembled and replaced, which is time-consuming and labor-intensive.

Jinyuan Forging has optimized the tooling die for shaft forgings and developed a modular forging die for shaft forgings, which facilitates the replacement of the arc shaping modules of the main working parts, saves materials and time, and improves efficiency. Different arc-shaped shaping modules can also be adapted to different working environments. For example, the invented composite tire mold for complex shaft forgings with shoulders and flanges can adapt to different lengths, steps, and shafts with flanges. Forging of forgings. In addition, it can effectively reduce the probability of mold damage, because when the shaft forgings with larger diameters are used, it often appears in the contact part of the upper and lower molds (upper and lower dies). Under impact extrusion, sharp corners are formed. After an impact cycle is over, the shaft forgings will rotate. The sharp corners formed will damage the mold or break away from the shaft forgings under impact. The detachable mold containing the rotating module for the round shaft forging can reduce the possibility of sharp corners on the shaft forging, protect the mold, and save materials.

　　Through continuous technological innovation, my country's current forging production efficiency and energy-saving level are close to the level of forging power Japan. Jiangsu Jinyuan has also become the pioneer of technological innovation in the domestic forging industry, especially high-speed and heavy-duty gear forging manufacturers.
