摘　　要：为了满足市场对FCD凸轮轴大量需求,总结原有凸轮轴生产经验,对凸轮轴模具进行了设计与改进,调整与优化了熔炼工艺、铸型工艺、铸造工艺,控制铸造缺陷,在2013LPDISA线上实现FCD700凸轮轴一模三件生产.车间生产过程中得到了稳定的铸造不良率、机加不良率和铸件尺寸.从目前生产的状况看,在工艺上解决了缩孔、缩松、气孔、渣孔、掉砂等缺陷的出现,降低了废品率,提高了FCD700凸轮轴的生产率.In order to meet a large market demand for FCD700 camshafts,a study is made on the mass production of FCD700 camshafts.Based on former experiences in camshaft production,a design of the camshaft mould is improved and the melting process,moulding process,and casting process are optimized to control the casting defects.Producing three pieces in a mould has been achieved for FCD700 camshafts on the 2013LP DISA production line.The actual production in workshop showed a stable casting rejection rate and machining rejection rate,stable casting size,and stable process.Viewing from present situation of production,such defects as shrinkage cavity,shrinkage porosity,pores,slag eyes,sand drop,etc.are avoided,so that the rejection rate is reduced and the productivity of FCD700 camshafts is improved.
