СURRENT STATE OF DEVELOPMENT OF ADVANCED FORGINGS PROCESSES

Volodymyr Borysevych, Zhang Xiang

Abstract


With the vigorous development of high-tech industries such as aviation and aerospace, new challenges have been brought to the traditional forging process. Forgings with a single structural feature and conventional forging processes in the past can no longer fully meet the development of contemporary industry. Therefore, it is urgent to develop new forging processes to meet the higher requirements for forgings. First of all, this article classifies the traditional forging processes, which helps to better understand the different types of forging processes. Then, the analysis of different types of forgings and their forming processes will help to better understand the forming characteristics of different methods of improvement. Comparative analysis found that the selection of forging process and route should fully consider the shape and size of the forgings. In actual production, often one type of forging may have multiple types of shape features. The complexity of the structure makes it impossible to obtain such forgings through only one type forging process or one-step forging. Greatly increased the difficulty of forging, limiting its development and application. Therefore, It is necessary to develop multi-types and multi-steps forging processes. And it is urgent to do further research on the metal forming mechanism and defect generation mechanism of complex forgings in the forging process.


Keywords
