摘要
为提高电解线切割的加工稳定性和加工效率,设计了一种电解线切割的多线切割装置。该装置可以装夹多根线电极,实现多线电极电解加工;采用了一种新的多线电极张紧装置,可以减小加工过程中线电极的抖动。利用多线电极电解线切割加工系统,进行了多线切割加工试验,探究主要工艺参数对加工质量的影响规律,试验结果表明:多线电极张紧装置有效地降低了加工过程中线电极的抖动,使加工稳定性大幅提高,避免了加工过程中出现短路现象;采用多线电极同时切割加工可以提高加工效率,同时采用复合电解液也可以提高加工效率。

The device can clamp mul ti -wire elect rode and achieve electrochemical machining of multi-wire electrode. A new multi-wire electrode tensioning device was used to decrease the vibration of electrode in the machining process. Wire electrochemical machining system of multi-wire electrode was applied for multi-wire cutting experiment to explore the influence rules of main technological parameters on machining quality. The experimental results show that the multi-wire electrode tensioning device effectively decreases the vibration of electrode in the machining process and improves the machining stability greatly. Meanwhile,the short-circuit phenomenon is avoided effectively. The machining efficiency may improve when multi-wire electrode is applied for cutting machining Besides, compound electrolyte can also promote the machining efficiency.
