多工位高速锻造技术是一种新型锻造技术,在很多发达国家已经得到广泛应用,它在提高生产效率的同时也节省了成本。利用Deform-2D软件分别对柴油机气门弹簧座多工位锻造的两种不同方案进行了数值模拟,对模拟得到的应力分布、载荷变化分布、变形量和损伤值分布等信息进行了分析与比较。优化目标要求在多工位高速锻造过程中每个工位模具载荷较小且每工位分布均匀,同时生产出的零件表面质量好,无裂纹。而第2种方案更符合此优化目标。经试验验证,按照第2种方案生产出的零件填充饱满,无裂纹等缺陷,更适用于采用多工位高速锻造的方法进行锻造。
Multi-station high-speed forging technology is a new type of forging technology, which has been widely used in many developed countries. It not only increases the production efficiency but also saves the cost. Deform-2D software was used to simulate two different schemes of diesel valve spring seat multi-station forging respectively. The stress distribution, load distribution, deformation and damage distribution were simulated and compared. The optimization goal requires that the mold load of each station should be small and each station should be evenly distributed in the multi-station high-speed forging process, and the surface quality of the produced parts is good and no cracks are produced. The second option is more in line with this optimization goal. The test proved that, according to the first two kinds of programs to produce parts filled full, no cracks and other defects, more suitable for multi-station high-speed forging method forging.
