Abstract

本發明係關於一種電化學加工工件(3)之裝置，其間在作為陽極之工件(3)及至少一作為陰極之電極之間建立一電勢差且經由一電解液進行一材料溶蝕，具有至少一加工工件表面(6)之電極段(1)及至少一加工工件凹空(7)之電極段(2)，且二電極段(1、2)可至少局部同時接觸在工件(3)上。

Description

電化學加工金屬工件之裝置
本發明係一種根據申請專利範圍第1項歸屬概念之電化學加工金屬工件之裝置。
在先前技術中習知使用電極加工事先變形之工件，該事先變形之工件在需要加工之區域內具有一尺寸裕度，需經由一電化學加工法(ECM或PECM)移除。DE 10 2009 032 563 A1例如係關於一種電極，其表面與需要加工之轉子葉片之外輪廓對應。為精密產生外輪廓，電極可用油壓調整。藉由電化學加工去除外表加工外亦可產生精密之微孔。其間在作為陽極之構件及作為陰極之電極間建立一電勢，且經由一電解液溶蝕移除構件材料。電解液通過電極或由電極側向被導引至需要加工之構件區。一種此類之電極公開於DE 10 2010 032 A1中。其具有一作用面，用以在一需溶蝕之側壁段及電極間定義一工作間隙。作用面設計成斜置或彎曲形。
本發明之目的在於，對以ECM或PECM溶蝕法加工之有孔及具有需加工表面之工件之加工，提速及使之精密化。
此目的藉由一種根據申請專利範圍第1項所述之裝置達成。有利之其他實施例說明於申請專利範圍附屬項。根據本發明一有利之實施例，為加工工件表面及孔，設置至少一具有兩段之結合電極，以之在一道工序中至少局部可同時加工工件表面及工件凹空，例如孔。以下將根據實施例詳細說明本發明。
在圖式中並未顯示電解液及電極與工件間之間隙。

2‧‧‧電極段，用以加工工件凹空
3‧‧‧工件
4‧‧‧中心銷
5‧‧‧工件容納器
6‧‧‧工件表面

11‧‧‧縱向進給方向

圖1及圖2：一用於加工凸輪盤之裝置
圖3a及圖3b：一電極，用於加工汽輪機葉片，特別是用於製造微孔及用於工件表面之材料移除
圖4a至圖4c：圖3之電極在工作接觸中
圖5：一加工完畢之工件
在圖1中一工件3被置於一工件容納器5中。作為工件3被加工者係一凸輪盤，具有一工件凹空7，其形式為一預先形成之孔。工件3被一伸入孔中之中心銷4正確固定位 置。中心銷4被一彈簧預力，且可抗拒彈簧力由孔中運動出來。
圖2顯示一在加工中之裝置。加工工件表面6之電極段1及加工工件凹空7之電極段2共同沈降至工件3上。中心銷4被電極段2壓迫。在預先形成之孔中經由材料溶蝕移除加工裕度及/或產生一輪廓。有利者係，凸輪盤之孔及外凸輪輪廓同時在一工件夾持中被加工。因而除縮短加工循環之時間外可獲最高精度之工件加工。
圖3a及圖3b顯示一用以加工汽輪機葉片之電極之上視圖及側視圖。電極段1及2共同設於一電極保持器10上。電極段1具有之一輪廓12其與加工之工件表面6相對應。製造微孔之電極段2分為二區域。鑽孔段8在縱向進給方向11探入工件中，且產生一孔，該孔接著被校準段9擴孔至最終尺寸。電極在工件上之齧入將藉助圖4a至圖4c詳細說明。圖4a顯示經由鑽孔段8製造一孔。隨著電極段2繼續探入工件3，校準段9亦齧入，將孔擴至完工直徑。最後圖4c顯示鑽孔之最終位置及經由電極段1加工之工件表面6。其間，在工件表面6上產生一輪廓12。特別有利者係，能以一單一進給運動既完成一工件凹空7亦在工件表面6上產生一輪廓12。為更好理解起見，工件3加工部分在圖5中分別以上視圖及側視圖顯示。在該處可看出工件凹空7及在工件表面6上之材料移除。
