- 摘要:
- 根据履带板铸件的结构特点,进行铸造工艺设计与优化。利用NX软件对履带板进行实体造型,并应用芸峰CAE软件模拟铸件的充型及凝固过程。结果表明,初始的单浇口-单冒口方案中金属液的充型方式容易使履带板的两端边缘形成卷气和夹渣缺陷。同时,由于单冒口的补缩作用不足容易使履带板的缺陷聚集于内部。通过增加内浇道的数量、改进补缩措施,使得充型过程更加均匀、稳定,凝固过程更加有序,有效控制了铸件缺陷。采用优化后铸造工艺生产履带板,减少了履带板铸件的气孔和夹渣缺陷,同时验证了模拟结果的正确性。According to the structural characteristics of crawler plate casting,the casting process design and optimization were carried out.NX software parts shall be used to conduct solid molding of the strap plate,and the filling and solidification process of the casting shall be simulated by Yunfeng CAE software.The results show that the filling mode of metal liquid in the initial single spout and single riser scheme is easy to cause the air entrapment and slag inclusion defects at both ends of the track plate.At the same time,due to the insufficient shrinkage of single riser,the defect of the strap plate is easily gathered in the inner part.By increasing the number of inner runner and improving feeding measures,the filling process is more uniform and stable,the solidification process is more orderly,and the casting defect is effectively controlled.The optimized casting process is used to produce crawler plate,which reduced the porosity and slag inclusion defects of crawler plate casting,and verified the correctness of the simulation results.
