摘要：

首先利用智慧芽专利大数据检索平台，梳理并分析了先进锻压各细分领域的热点技术及其全球分布情况与发展态势；继而采用可视化方法，对比分析了锻压领域各细分方向的全球主要研发实体及其重点技术布局、创新情况。结果表明：中国在先进锻压领域的专利总量全球排名第一，但日本、美国、德国的部分先进锻压技术仍处于全球领先水平；锻压前沿热点技术主要集中在高速精密锻造、锻压模具、锻件质量检测、连续锻造、锻压操作机、锻压数字化等方向；应用主要集中在航空航天大型模锻件、发动机环形锻件、钛合金锻件，汽车覆盖件、铝合金轮毂、燃料电池板，高速列车制动器轮毂、盘体，复杂薄壳体、风电发动机主轴等领域。

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.
