The spinning press technology is a time-honored traditional technique, documented to have originated in the Tang Dynasty of our country. The spinning press evolved from the ceramic-making process into the metal spinning technique.20Since the mid-20th century, with the development of the industry and the expansion of the aerospace sector, the spinning process has been widely applied in the field of sheet metal forming, thereby promoting the research and development of this technology. After the mid-20th century, significant advancements in the general spinning process of spinning machines have been made in the following three aspects: the gradual mechanization and automation of general spinning equipment, and...20Century50The era of equipment simulating manual spinning was introduced, which utilizes hydraulic actuators to drive the mandrel in reciprocating motion, thereby achieving feed and return movements, thus reducing the labor intensity.
Appropriate heat treatment of the spinning machine can refine the internal grain structure of the metal and alter the crystal phase organization, thereby changing the metallic properties. Consequently, people have begun to combine heat treatment technology with spinning technology, creating new spinning processing methods and laying a new milestone for spinning machine technology. In recent years, many scholars have also conducted extensive research on the combination of heat treatment and spinning processing. Although the aforementioned research on spinning machines has provided theoretical support and practical guidance for the application of aluminum alloy spinning technology in industrial production, with the development of industrial production, to meet the increasing demands, the authors believe that the development of aluminum alloy spinning technology in the following directions will have epoch-making significance. With the advancement of technology, the requirements for spinning machine equipment products are also increasing. Due to the processing hardening and other defects that occur during the cold spinning process, the cold spinning technology is no longer capable of meeting production demands.
The lathe press, when utilizing CNC technology, can achieve the following effects to some extent.,Reducing preparation and processing times, adapting to changes in processing conditions, improving repeat processing accuracy, and preventing accidents before they occur. However, certain aspects can also be achieved by some new hydraulic profiling automatic spinning machines. Moreover, regardless of the control method used for CNC spinning machines, the determination and placement of the spinning wheel passes largely depend on the operator's skill. Therefore, CNC automatic programming technology will be an important research topic in the future, and it should only input the shape of workpieces according to certain standard procedures.,The size and shape of the roller determine the number of passes in the roller track and enable the production of qualified products.
The application of spinning machine technology is becoming increasingly widespread, with ever-higher demands placed on spinning machine tools, particularly for those with large turning diameters, high thrust, high precision, and high levels of automation. Overseas high-force spinning machines have been serialized and are continually evolving towards larger sizes, multi-functional spinning machines, and higher levels of automation. With the development of computer technology, the control systems of spinning machine tools are also advancing. The feeding of spinning wheels has fully developed into CNC, the spindle speed has evolved from stepless to variable, and multi-spindle rotating stands for spinning machines have been developed. Televisions for monitoring large diameter parts and ultrasonic automatic thickness measurement devices for wall thickness have also been applied to spinning machine tools.
