This paper analyses the development and research of headless welding and rolling technology and its applications in actual production.
Headless welding and rolling technology is a kind of advanced forging technology, which is mainly used in the production of shaft parts, connecting parts, seamless pipes and other parts, so as to obtain the advantages of welding and forging.It is characterized by welding and forging simultaneously, and welding the raw materials while rolling them into semifinished products, to replace the process of forging and welding.
In the research of headless welding and rolling technology, many studies focus on the method of controlling surface profiles, dynamic simulation, welding surface instability and other theoretical issues.In the early1990s, a research group from the city university in Paris first adopted the technology of headless welding and rolling for shaft production, which greatly improved the production efficiency and accuracy.Then, researchers from many universities and research institutes continued to study and improve the technology.
In the research of headless welding and rolling technology, micrometer rolling is often mentioned.It is the use of a high-precision rolling mill to roll the raw material roll and achieve the required profile size and shape.In the actual process, the conventional rolling method does not meet the requirements, and the micrometer rolling method is adopted to complete the processing requirements and obtain the required material profile.
At the same time, with the development of high-precision and large-scale rolling technology, the research of headless welding and rolling technology is also being deepened.In the comprehensive application of headless welding and rolling technology, the overall process stability and material properties of the products produced have been further improved.At the same time, many technological measures have been taken to improve the welding precision and surface quality of the products, thus to ensure the quality control and precision control of the welding technology.
With the development and widespread application of headless welding and rolling technology, the consumption of materials and energy has been greatly reduced, and the processing speed has also been improved significantly.At present, this technology has been significantly improved, and has been widely used in the production of automobile, railway and other industries.For example, in the production of automobiles, wheel hub and wheel splines are also produced by this technology, which can greatly improve product quality and reduce production cost.
In conclusion, headless welding and rolling technology has a wide range of applications in the production of shaft parts, connecting parts, seamless pipes and other parts.Its application has promoted the improvement of production quality and efficiency, greatly reducing material and energy consumption.At present, it has been increasingly used in many industrial fields, and its development potential is great.
