摘　　要：针对Invar钢模具型板形状复杂多样,传统加工方法效率低、质量低等缺点,借鉴双曲度船体外板成形加工经验,对活络方形压头非对压技术在Invar模具型板预成形加工上的适应性进行了研究。对Invar钢的材料特性、形状特点、成形工艺进行了分析,成形结果表明活络方形压头非对压技术结合大吨位油压机能够有效地加工Invar钢模具型板,成形精度满足Invar钢模具型板预成形生产要求。In view of the complexity and diversity of Invar alloy mould plate shape, the low efficiency and low quality of traditional processing methods, on the basis of actual production and referring to the experience of ship hull plates forming process, the adaptability of the rotary square punch and non-pair stamping technology on Invar mould plate forming was studied. The material characteristics, shape characteristics and forming process of Invar alloy are analyzed, and it is indicated that the rotary square stamping punch combined with the large tonnage oil press can effectively form the Invar alloy mold plate, and the forming error is less than the production demand.
