Historical development of hot closed die forging

Hot closed die forging machine manufacturer and supplier in China

Hot closed die forging is an important metal forming process by heating the metal above the recrystallization temperature and then using a mold to plastically shape it to the desired shape and size. The application of this technology in industry has a long history and continues to develop and evolve over time.
Early development
The history of hot closed die forging dates back to ancient times, when people began to use simple hammers and cutting blocks to forge metal. With the progress of metallurgical technology, the forging process has gradually developed from manual forging to mechanical forging. At the end of the 19th century, with the advancement of the industrial revolution, the appearance of forging machinery such as steam hammers and mechanical presses made the hot closed die forging technology significantly developed.
Early 20th century
In the early 20th century, with the rise of the automobile industry, hot closed die forging technology has been widely used. Auto parts such as crankshaft, connecting rod and so on need high strength and high precision forgings, and hot closed die forging just meet these requirements. At this time, hot closed die forging has become one of the main methods in the forging process.
Mid-20th century
In the middle of the 20th century, hot closed die forging technology was further developed. Hot die forging presses, flat forging machines and anvilless forging hammers have gradually replaced traditional ordinary forging hammers, improving production efficiency and reducing vibration and noise. In addition, with the development of material science, the emergence of new alloy materials has also promoted the progress of hot closed die forging technology. For example, the application of titanium alloy and superalloy makes hot closed die forging widely used in the aerospace field ⁴.
Modern development
In the 21st century, hot closed die forging technology has made significant progress in precision and efficiency. Modern hot closed die forging equipment adopts numerical control technology and automatic control system, which makes the forging process more accurate and efficient. At the same time, the development of computer simulation technology also provides strong support for the optimization of hot closed die forging process. By computer simulation, the process parameters can be optimized before forging, so as to improve the quality of forging and production efficiency ⁵.
The expansion of the application field
The application of hot closed die forging technology in industry is expanding continuously. In addition to the traditional automotive and aerospace fields, hot closed die forging is also widely used in energy, construction, medical equipment and other fields. For example, in the energy sector, hot closed die forging is used to manufacture high-strength components for wind turbines; In the field of construction, hot closed die forging is used to produce high-strength steel structural parts; In the field of medical devices, hot closed die forging is used to manufacture high-precision surgical instruments ⁶.
Future development trend
Looking forward to the future, the hot closed die forging technology will continue to develop in the direction of intelligence and green. In terms of intelligence, with the application of artificial intelligence and Internet of Things technology, hot closed die forging equipment will achieve more intelligent control and monitoring, thereby further improving production efficiency and product quality. In terms of green, the hot closed die forging process will pay more attention to energy saving and emission reduction, and reduce energy consumption and environmental pollution by optimizing process parameters and using new environmentally friendly materials.
In short, as an important metal forming process, hot closed die forging technology has experienced a long development process from manual forging to mechanical forging, and then to modern intelligent forging. With the continuous progress of science and technology, hot closed die forging technology will play an important role in more fields, providing more efficient and high-quality solutions for industrial production.
