摘要
就机床铸件的变形、开裂等失效问题,对国外高端数控机床铸件结构和材料等生产控制技术进行了相关研究,发现机床失效的主要问题点在铸件的结构强度低和材料刚性差,使得铸件应力变大,机床因铸件应力释放而发生变形,精度丢失.通过铸造模拟分析,反向优化铸件结构、浇注系统等,以高碳当量+复合合金化的熔炼工艺,配合复杂的时效工艺,实现了高强度低应力铸件的生产.
Abstract
On the machine tool casting deformation,cracking and other failure problems,the foreign high-end CNC machine tool casting structure and material production control technology was studied,found that the main problem of machine tool failure in the casting structure strength is low and the material rigidity is poor,so that the casting stress becomes large,the machine tool deformation due to the casting stress release,precision loss.Through casting simulation analysis,reverse optimization of casting structure,pouring system,etc.,with high carbon equivalent+composite alloying melting process,combined with complex aging process,the casting of high strength and low stress castings is realized.
