摘　　要：通过分析风管式空调内机支撑脚零件成型的工艺特点,在原有单冲工艺(冲孔落料→冲圆孔→弯曲→Z形压舌弯曲→V形弯曲(含三角加强筋)共5副模具)的基础上,提出了1套连续模冲压的方案(分步多次冲孔→压舌→分步多次弯曲→冲孔→弯曲→切断)。重点阐述了该零件冲压成型的排样、模具结构以及模具的工作原理。该连续模成功替代了原有的单冲模,产品质量稳定,为企业节省了生产成本,提高了生产效率和经济效益。According to the forming process features of the support leg of an air conditioner,a continuous die(Step and multiple punching→tongue pressing→step and multiple bending→punching→bending→cutting)was presented after processing improvements on the basis of the original single step(punchingand blanking→hole punching→bending→Z-shaped tongue bending→V-shaped bending,5 sets of dies in total)pressing processes.The layout,structure and working principle of the aforementioned punching and forming die were introduced.The continuous die has been successfully developed to replace the original single punch die,saves the production cost,improves production efficiency,increases economic benefits and ensures the stability of product quality.
