激光切割机用横梁的无模铸造工艺优化设计研究

Research on Optimization Design of Moldless Casting Process for Beams Used in Laser Cutting Machines

激光切割机作为现代机械加工中重要的特种加工设备,其Y轴横梁结构复杂,制造难度大。为避免横梁结构砂铸过程中出现气孔、缩松、浇不足等缺陷,设计了双侧底注式浇注系统。结果表明,采用无模铸造成形技术设计了铸造型芯,采用Procast软件仿真优化了浇冒口工艺,最终确定了激光切割机横梁的铸造工艺方案。

Laser cutting machine was an important special processing equipment in modern machining.The Y-axis beam was complex and difficult to manufacture.In order to avoid the defects such as porosity,shrinkage and loose,and insufficient pouring in the process of sand casting of beam structure,a two-side bottom pouring system was designed.The results show that the casting core is designed by the model-free casting technology,the casting riser process is optimized by Procast software simulation,and the casting process scheme of the beam of the laser cutting machine is finally determined.
