在锻压技术中,体积成形仍然占有重要地位,由于冷体积成形工艺的发展,其产量还有提高的趋势,而近来热模锻的产量几乎停滞不前。模锻工艺正受到取代性竞争的压力,尤其是来自浇注工艺的压力。这就要求挖掘模锻工艺本身的潜力。近几年来,冷体积成形的加工范围有所扩 In forging technology, volume forming still occupies an important position, due to the development of cold volume forming process, there is an increasing trend of its output, and recently the production of hot forging almost stagnated. Die forging is under pressure to replace competition, especially from casting processes. This requires mining the potential of forging process itself. In recent years, the processing range of cold forming has expanded
