摘要
在连杆裂解槽线切割机床加工过程中,工作液中会混入微米级的固体颗粒和亚微米级的悬浮物,前者来自工件与电极丝放电气化蚀除的金属产物,后者来自工件材料受高温气化分解及工作液分解的微细产物,这些金属微粒会影响工件与电极丝之间放电间隙的形成,进而影响连杆裂解槽的加工质量与效率。针对工作液在加工过程中颗粒成分及温度的变化,设计了新型连杆裂解槽线切割机床工作液过滤系统,并通过实验证明了设计的可行性。
In the process of fracture splitting connecting rod,working fluid often mix in micrometer-scale solid particle and sub-micrometer-scale suspended solids,the former from the vaporization product of work with wire electrode,the later from the microscopic product of work and liquid because of high temperature,these particle affect the formation of discharge gap,and definitely the quality of working liquid is vital to the process. Due to the variations of conductivity and temperature of working liquid,a working fluid filtration system is put forward,and verify the feasibility of this design.
