一般冲裁模的排样方案在保证材料辗压流向要求的基础上以考虑材料的利用率为主。在包括成形、弯曲等工步的级进模中,排样方案只能是在保证纹向要求的基础上,以考虑成形、弯曲等工步的工艺上可能性、合理性、可靠性为主,其次再考虑材料的利用率,一般倩况下,一次成形级进模因生产效率的成倍提高而取得的收效远远超过材料利用率降低的损 General blanking die layout program to ensure the material flow requirements based on the rolling to consider the utilization of materials based. In the progressive die including forming, bending and other steps, the arrangement plan can only be based on the requirement of guaranteeing the warp direction, taking into consideration the process feasibility, rationality and reliability of steps such as forming and bending , And then consider the material utilization, under normal circumstances, a forming progressive die due to double the production efficiency and achieved much better results than the reduction of material utilization loss
