新型往复走丝电火花线切割机床设计

Design of a New Type of Reciprocating Travelling Wire Electrical-discharge Machines

目前的往复走丝电火花线切割机床大多采用机床本体、电气箱、工作液箱三者分离的分体式结构,其储运较复杂;有些采用一体式结构的,由于电气箱紧凑安装于机床本体上,电气箱所带来的热量导入床体后会对机械精度产生不利影响,且工作液箱使用时还是分离的。针对这些弊端,研发了新型一体式结构的往复走丝电火花线切割机床,同时通过特殊隔热设计,克服了目前一体式结构的缺陷,提升了机床的整洁、美观和自动化程度。

Split type structure is widely used in high speed wire-cut electric discharge machine.The machine body, the electrical cabinet and the dielectric fluid cistern are detached. This structure is difficult in storage and transportation. On account of those defects,all-in-one structure is conducted,but the heat produced by the electrical cabinet will have detrimental effects on mechanical precision. In addition,the dielectric fluid cistern is still split. In view of these disadvantages,new high speed wirecut electric discharge machine is designed and introduced in this paper. Because of thermal insulation design,some disadvantages are overcame and machine tool′ s aesthetics and the degree of automation are improved.
