Abstract：

Firstly, the hotspot technologies and their global distribution and development trend in various subdivided fields of advanced forging were analyzed based on Patsnap patent big data retrieval platform, and then, the main global R&D entities and companies in each subdivided direction of forging field and their key technology layouts and innovations status were analyzed comparatively by the visualization method. The results indicate that China ranks first in the world in terms of the total number of patents in the advanced forging field, but some advanced forging technologies in Japan, the United States and Germany are still at the leading level in the world. The frontier hotspot technologies in forging mainly focus on high-speed precision forging, forging dies, quality inspection of forgings, continuous forging, forging manipulator, forging digitalization and other technical directions, and its applications are concentrated in the fields of large aerospace die forgings, engine ring forgings, titanium alloy forgings, automobile panels, aluminum alloy wheels, fuel cell plates, high-speed train brake wheels, disks, complex thin shells and wind power engine spindles.
