Description
本發明係有關於一種電化學複合刷磨加工裝置，特別是將電極給液、電化學加工與刷磨加工的優點予以整合，並且透過電極給液之設計，克服於三維自由曲面加工時工作物之幾何遮蔽，深孔特徵或階梯形貌之障礙，使電解液得以經過電極流到該金屬工件的加工區域，同時進行電化學加工與研磨的動作，使供給電解液、電化學加工與刷磨加工得以同步進行的一種裝置。 The present invention relates to an electrochemical composite brushing and grinding device, especially integrating the advantages of electrode feeding, electrochemical machining and brushing processing, and through the design of electrode feeding, it overcomes the problem of working objects when processing three-dimensional free-form surfaces. The geometric shielding, the obstacle of deep hole feature or step shape, so that the electrolyte can flow to the processing area of the metal workpiece through the electrode, and the action of electrochemical machining and grinding is carried out at the same time, so that the supply of electrolyte, electrochemical machining and brushing A device in which processing is carried out simultaneously.
電化學加工是藉由電能轉換為化學能，將材料經由陽極溶解而達到移除之目的。因為刀具電極不與工件接觸，因此不會產生接觸應力以及造成刀具磨損的情況產生，只是，在電化學的加工過程中，因電解液的導電度衰退、供給不足、無法充填至欲加工表面，因而造成加工表面的不均勻腐蝕，例如：過度腐蝕造成晶粒缺陷，導致加工表面瑕疵。此外，不足的陽極反應造成金屬表面產生包覆緻密的金屬氧化膜，而金屬氧化膜會隔絕金屬與電解液，最終使金屬無法溶解而阻礙材料移除，影響電化學加工的加工效率。因此，必須透過精確且穩定的給液機制，運送電解液至加工區， 產生電化學反應，並且搭配刷磨加工移除氧化膜，活化金屬材料之加工表面，才能使電化學加工有效地進行材料移除，同時達到節能之效果。 Electrochemical machining is the conversion of electrical energy into chemical energy, and the removal of materials through anodic dissolution. Because the tool electrode is not in contact with the workpiece, there will be no contact stress and no tool wear. However, during the electrochemical machining process, due to the decline in the conductivity of the electrolyte and insufficient supply, it cannot be filled to the surface to be processed. As a result, uneven corrosion of the machined surface is caused, for example: excessive corrosion causes grain defects, resulting in flaws on the machined surface. In addition, insufficient anodic reaction results in the formation of a dense metal oxide film on the metal surface, and the metal oxide film will isolate the metal from the electrolyte, eventually making the metal insoluble and hindering material removal, affecting the processing efficiency of electrochemical machining. Therefore, it is necessary to deliver the electrolyte to the processing area through an accurate and stable liquid supply mechanism. Electrochemical reaction is generated, and combined with brushing to remove the oxide film and activate the processed surface of the metal material, the electrochemical processing can effectively remove the material and achieve the effect of energy saving.
目前，經由外部給液的電化學加工系統，會因加工物之幾何遮蔽，深孔特徵或階梯形貌，導致外部給液無法進入加工區。如果要同時進行給液與電極移動二種加工動作，必須將大量的給液噴嘴安置於加工表面附近，以淹沒(die-sinking)的方式進行，但是因為電極之移動與加工面之起伏、噴嘴如果沒有隨之自動調整方向與流量，進入加工區之電解液會產生不穩定之流量與壓力變異，造成電流做功之異常，產生過度電化學反映或不足之電化學反應。此結果極為容易造成不連續之材料移除量，甚至是中斷材料移除加工，造成在幾何遮蔽，深孔特徵或階梯形貌之自由曲面連續加工的失敗。 At present, the electrochemical machining system with external liquid supply cannot enter the processing area due to the geometric shielding of the workpiece, deep hole features or step shape. If liquid feeding and electrode movement are to be performed at the same time, a large number of liquid feeding nozzles must be placed near the processing surface in a die-sinking manner. However, due to the movement of the electrode and the fluctuation of the processing surface, the nozzle If the direction and flow are not automatically adjusted accordingly, the electrolyte entering the processing area will produce unstable flow and pressure variations, resulting in abnormal current work, resulting in excessive or insufficient electrochemical reactions. This result is extremely easy to cause discontinuous material removal, or even interrupt material removal processing, resulting in the failure of continuous processing on free-form surfaces with geometric shadows, deep hole features or stepped topography.
有鑑於此，本發明的目的在於提供一種電極給液型電化學複合刷磨加工裝置，可以直接裝設於傳統CNC多軸加工母機，使傳統CNC多軸加工母機提昇為具有電化學加工與電化學研磨功用，不需安裝多噴嘴，並且可以克服加工面之幾何遮蔽，不需拆卸工件、移動再組裝至另一加工機上，即可進行節省時間與操作空間之電化學加工；並且藉由從電極連續給液之複合式加工設計能夠獲得電化學加工與研磨刷研磨兩製程之各別優勢，藉以提高製程之材料移除率、改善表面粗糙度並得到殘留壓應力之表面。 In view of this, the purpose of the present invention is to provide an electrode liquid-feeding type electrochemical compound brushing and grinding device, which can be directly installed on the traditional CNC multi-axis machining machine, so that the traditional CNC multi-axis machining machine can be upgraded to have the functions of electrochemical machining and electrochemical machining. It has the grinding function, does not need to install multi-nozzles, and can overcome the geometric shielding of the processing surface. It does not need to disassemble the workpiece, move it and assemble it to another processing machine, and can perform electrochemical processing that saves time and operating space; and by The composite processing design of continuous liquid supply from the electrode can obtain the respective advantages of the two processes of electrochemical machining and abrasive brush grinding, so as to improve the material removal rate of the process, improve the surface roughness and obtain the surface with residual compressive stress.

當加工開始時，該中心主軸10帶動該浮動刀把模組30之該電極32與該些陶瓷研磨刷332旋轉，該些陶瓷研磨刷332搭配適當的下壓力(7N)、研磨轉速(400rpm)刷磨該金屬工件M的表面，同時以電壓(Open voltage：25V,Pulse-on time：0.5s,Pulse-off time：0.5s)產生電流並經由電源輸入導線46流至該電極32，電解液L(9.6L/min)流至加工區域內，電流與電解液反應，完成使用本發明之電極給液型電化學複合刷磨加工裝置100所預期之電化學反應和機械刷磨之複合效果。又，在加工過程中所使用的下壓力、研磨轉速、電流量、及電解液流速等操作參數可依該金屬工件M的物性進行調整，在此不特別加以限制。另外，該電極32的外觀型態可以是柱體、錐體、或是不規則立體，而開設於電極32中之出液孔的數量也可以是一個或是多個，可依離子濃度與流量進行計算對應之面積與流體之流速，並依電極32的外觀型態進行調整及變化。

本發明所揭示的電極給液型電化學複合刷磨加工裝置100可以依照實際需求設計加工電極之幾何尺寸以及陶瓷研磨刷之幾何外型；再者，通過該中心主軸10的帶動，該浮動刀把模組30可以控制加工時該複數陶瓷研磨刷332之下壓力，調整研磨深度。本發明還設計了以主軸中心輸入電解液L的機構，電解液L儲存於該電解液儲存槽20，該電解液儲存槽20作為電解液L之緩衝區域，並接著由該浮動刀把模組30之該電極32中心往下送至金屬工件M的加工區域，再搭配設計旋轉電極之電流輸入機構，利用氣壓缸保持該電極32與傳遞電流之石墨導電件44接觸，使電流可以進行穩定傳遞；且，該陶瓷研磨刷332固定於之電極32上，該陶瓷研磨刷332係跟著該電極32一同旋轉，進而達到同步進行電化學與刷磨加工之目的。
The electrode liquid-feeding type electrochemical compound brushing and grinding
綜上所述，本發明藉由整合電化學加工與研磨刷研磨兩製程為一複合式加工而獲得各別之優勢，同步加工之概念可節省二次加工的時間浪費；並且解決電化學加工過程中，在工件陽極之鈍化現象阻礙反應之問題。再者，本發明之電解液儲存槽20與浮動刀把模組30的機構設計可將電解液經由電極中心連續給液，讓電解液能夠直接地進入加工區，使旋轉之電極仍可維持高導電性之電解加工環境，進而提升電化學加工之反應速率，亦即增加材料移除率。另外，本發明之導電模組與浮動刀把模組30的機構設計能夠克服將電流輸入旋轉零件之困難，達到穩定傳遞電流之目的。
