Description
本發明係有關於一種電化學加工，尤指一種感應式電化學加工裝置及其加工方法。The invention relates to an electrochemical machining, especially an inductive electrochemical machining device and a machining method thereof.
現今對工件進行加工之方式，大都利用刀具直接接觸工件，而以機械力切削工件，然而運用機械力對工件進行加工，因為刀具係直接接觸工件，所以加工後之工件的表面會殘留應力，如此加工後之工件會容易有應力集中的現象，如此容易導致工件變形，尤其是薄形工件，且加工後之工件的表面容易具有加工痕跡，因此加工精度有限。此外，若工件之材料為高硬度材料，機械力則難以對工件進行加工，且容易造成刀具磨損，而減低刀具的使用壽命，如此即會增加加工成本。Most of the current methods of processing workpieces use tools to directly contact the workpieces and cut the workpieces with mechanical force. However, the mechanical forces are used to process the workpieces. Because the tools directly contact the workpieces, the surface of the processed workpieces will have residual stresses. After processing, the workpiece will be prone to stress concentration, so it is easy to deform the workpiece, especially the thin workpiece, and the surface of the processed workpiece is likely to have processing marks, so the processing accuracy is limited. In addition, if the material of the workpiece is a high-hardness material, it is difficult to process the workpiece by mechanical force, and it is easy to cause tool wear and reduce the service life of the tool, which will increase the processing cost.
本發明之一目的，在於提供一種感應式電化學加工裝置及其加工方法，其不需要利用刀具接觸工件，而可對工件進行加工。An object of the present invention is to provide an inductive electrochemical machining device and a machining method thereof, which can process a workpiece without using a tool to contact the workpiece.

本發明係有關於一種感應式電化學加工裝置，其包含一工件容置空間、一第一極性感應電極模組與一第二極性感應加工電極模組。第一極性感應電極模組與第二極性感應加工電極模組皆相鄰於工件容置空間。The invention relates to an induction type electrochemical machining device, which includes a workpiece accommodating space, a first polarity induction electrode module and a second polarity induction machining electrode module.

為使 貴審查委員對本發明之特徵及所達成之功效有更進一步之瞭解與認識，謹佐以實施例及配合詳細之說明，說明如後：In order to make your inspection committee have a better understanding and understanding of the features and effects of the present invention, the examples and detailed descriptions are accompanied by the following explanations:
請參閱第一A圖與第一B圖，其為本發明之感應式電化學加工裝置之第一實施例之兩不同視角的立體示意圖。如圖所示，本發明之感應式電化學加工裝置1可對一工件2進行電化學加工。感應式電化學加工裝置1包含一第一極性感應電極模組11、一第二極性感應加工電極模組13與一工件容置空間100。工件容置空間100用於容置欲進行電化學加工之工件2，且電解液亦會提供至工件容置空間100，以進行電化學加工，而第一極性感應電極模組11與第二極性感應加工電極模組13皆相鄰於工件容置空間100。Please refer to FIGS. 1A and 1B, which are schematic perspective views of two different viewing angles of the first embodiment of the induction electrochemical machining device of the present invention. As shown in the figure, the inductive electrochemical machining device 1 of the present invention can perform electrochemical machining on a workpiece 2. The inductive electrochemical machining device 1 includes a first polarity sensing electrode module 11, a second polarity sensing processing electrode module 13 and a workpiece accommodating space 100. The workpiece accommodating space 100 is used for accommodating the workpiece 2 to be electrochemically processed, and the electrolyte is also provided to the workpiece accommodating space 100 for electrochemical processing, and the first polarity sensing electrode module 11 and the second polarity The induction machining electrode modules 13 are all adjacent to the workpiece accommodating space 100.
第二極性感應加工電極模組13用於對工件2之至少一加工表面進行電化學加工，因此第二極性感應加工電極模組13相對於工件2之加工表面。第一極性感應電極模組11利用於形成一電源迴路，其可以相對於工件2之預定不進行加工之至少一非加工表面。工件容置空間100對應於工件2之加工表面的區域即為電化學加工區101，而工件容置空間100對應於工件2之非加工表面的區域即為非電化學加工區103、105。於本發明之一實施例中，工件2可為一薄型工件或者為一帶狀工件，而可以進行連續性的電化學加工。The second polarity induction machining electrode module 13 is used to electrochemically process at least one machining surface of the workpiece 2, so the second polarity induction machining electrode module 13 is relative to the machining surface of the workpiece 2. The first polarity sensing electrode module 11 is used to form a power circuit, which can be relative to at least one non-processed surface of the workpiece 2 that is not scheduled to be processed. The area of the workpiece accommodating space 100 corresponding to the machining surface of the workpiece 2 is the electrochemical machining area 101, and the area of the workpiece accommodating space 100 corresponding to the non-machining surface of the workpiece 2 is the non-electrochemical machining area 103, 105. In one embodiment of the present invention, the workpiece 2 may be a thin workpiece or a belt-shaped workpiece, and continuous electrochemical machining may be performed.
於此實施例中係以感應式電化學加工裝置1對工件2之兩側表面的下部位表面201進行電化學加工而形成尖部為例進行說明，但不限制本發明之感應式電化學加工裝置1與方法僅能用於形成尖部。由此可知，此實施例之工件2之兩側表面的下部位表面201為加工表面，而其餘部位之表面即為非加工表面。此外，工件容置空間100相對於工件2之兩側表面的下部位表面201的區域為電化學加工區101，而工件容置空間100相對於工件2之其餘部位之表面的區域即為非電化學加工區103、105。如第一A圖與第一B圖所示，第二極性感應加工電極模組13相對於工件2之兩側表面的下部位表面201，而第一極性感應電極模組11則可相對於兩側表面的上部位表面203。In this embodiment, the inductive electrochemical machining apparatus 1 is used to perform electrochemical machining on the lower surface 201 of the two surfaces of the workpiece 2 to form a sharp portion as an example, but it does not limit the inductive electrochemical machining of the present invention. The device 1 and method can only be used to form a tip. It can be seen that the lower surface 201 of both sides of the workpiece 2 in this embodiment is a processed surface, and the surfaces of the remaining parts are non-processed surfaces. In addition, the area of the lower surface 201 of the workpiece accommodating space 100 with respect to both sides of the workpiece 2 is the electrochemical machining area 101, and the area of the workpiece accommodating space 100 with respect to the surface of the rest of the workpiece 2 is non-electrochemical School Processing Zone 103, 105. As shown in FIGS. 1A and 1B, the second polarity induction machining electrode module 13 is opposite to the lower surface 201 of both side surfaces of the workpiece 2, and the first polarity induction electrode module 11 can be opposite to the two The upper surface 203 of the side surface.
於此實施例中，第一極性感應電極模組11包含兩個第一極性感應電極110與111，第一極性感應電極110與111可分別相對於工件2之兩側表面的上部位表面203，即可相對於工件容置空間100之非電化學加工區103之兩側。此外，為了避免工件2之下端面205，即尖部的端部，受到電化學加工之影響而過度薄化，下端面205亦可預設為非加工表面。本發明之感應式電化學加工裝置1更可包含一阻加工感應電極模組15，其可包含一阻加工感應電極151，其相對於工件容置空間100之底部的非電化學加工區105，而相對於工件2之下端面205。於此實施例中，阻加工感應電極151具有一尖端1511，且尖端1511相對於工件2之下端面205，以保護下端面205，進而形成尖端於下端面205。In this embodiment, the first polarity sensing electrode module 11 includes two first polarity sensing electrodes 110 and 111, and the first polarity sensing electrodes 110 and 111 may be opposite to the upper surface 203 of the two side surfaces of the workpiece 2, respectively. That is, both sides of the non-electrochemical machining area 103 of the workpiece accommodating space 100 are opposite. In addition, in order to avoid excessive thinning of the lower end surface 205 of the workpiece 2, that is, the end of the tip portion, due to the influence of electrochemical machining, the lower end surface 205 may also be preset as a non-machined surface. The induction electrochemical machining device 1 of the present invention may further include a resistance machining induction electrode module 15, which may include a resistance machining induction electrode 151, which is opposite to the non-electrochemical machining area 105 at the bottom of the workpiece accommodating space 100, And relative to the lower end surface 205 of the workpiece 2. In this embodiment, the resistance processing sensing electrode 151 has a tip 1511, and the tip 1511 is opposite to the lower end surface 205 of the workpiece 2 to protect the lower end surface 205, thereby forming a tip on the lower end surface 205.
第二極性感應加工電極模組13包含兩個第二極性感應加工電極130、131，兩者分別相對於工件2之兩側表面的下部位表面201，即兩者分別相對於工件容置空間100之電化學加工區101之兩側。由上述說明可知，本發明之第一極性感應電極模組11與阻加工感應電極模組15之所在位置是依據對工件2之加工需求而決定，即依據工件2之加工表面之位置與未加工表面之位置而決定，並未限定兩者必須設置於某一固定位置。此外，本發明之感應式電化學加工裝置1也不一定需要阻加工感應電極模組15。第一極性感應電極模組11也並未限定設置於某一固定位置。The second polarity induction processing electrode module 13 includes two second polarity induction processing electrodes 130 and 131, which are respectively opposite to the lower surface 201 of the two surfaces of the workpiece 2, that is, the two are respectively relative to the workpiece accommodating space 100 Both sides of the electrochemical machining area 101. As can be seen from the above description, the positions of the first polarity sensing electrode module 11 and the resistance processing sensing electrode module 15 of the present invention are determined according to the processing requirements of the workpiece 2, that is, according to the position of the processed surface of the workpiece 2 and the unprocessed The position of the surface is determined, and it is not limited that the two must be set at a fixed position. In addition, the inductive electrochemical machining device 1 of the present invention does not necessarily need to process the sensing electrode module 15. The first polarity sensing electrode module 11 is not limited to a fixed position.
請一併參閱第二圖，其為本發明之感應式電化學加工裝置之第一實施例之電性示意圖。如圖所示，感應式電化學加工裝置1更包含一電源模組17。電源模組17具有一正極端171與一負極端172。電源模組17之負極端172連接第二極性感應加工電極模組13之第二極性感應加工電極130、131，使第二極性感應加工電極130、131具有複數個負電荷N1，工件2相對於帶有負電荷N1之第二極性感應加工電極130、131之表面（加工表面）201即會感應產生複數個感應正電荷P2，所以工件2之表面201即相當於電化學加工之陽極，而會被溶解，即進行移除加工而減薄。Please also refer to the second figure, which is an electrical schematic diagram of the first embodiment of the inductive electrochemical machining device of the present invention. As shown in the figure, the induction electrochemical machining device 1 further includes a power module 17. The power module 17 has a positive terminal 171 and a negative terminal 172. The negative terminal 172 of the power module 17 is connected to the second polarity induction machining electrodes 130, 131 of the second polarity induction machining electrode module 13, so that the second polarity induction machining electrodes 130, 131 have a plurality of negative charges N1, and the workpiece 2 is opposite to The surface (processed surface) 201 of the second polarity induction machining electrodes 130 and 131 with negative charge N1 will induce a plurality of induced positive charges P2, so the surface 201 of the workpiece 2 is equivalent to the anode of electrochemical machining, and will When it is dissolved, it is removed and thinned.
正極端171連接第一極性感應電極模組11之第一極性感應電極110、111，以形成電源迴路。此外，正極端171亦連接阻加工感應電極模組15之阻加工感應電極151。因為第一極性感應電極110、111與阻加工感應電極151連接正極端171，因此第一極性感應電極110、111與阻加工感應電極151具有複數個正電荷P1。工件2相對於帶有正電荷P1之第一極性感應電極110、111與阻加工感應電極151之表面（非加工表面）203、205即會感應產生複數個感應負電荷N2，因此工件2之表面（非加工表面）203、205即會產生該些個感應負電荷N2，所以工件2之表面203、205即相當於電化學加工之陰極，而不會被溶解。由上述可知，第一極性感應電極110、111亦可保護工件2之非加工表面。The positive terminal 171 is connected to the first polarity sensing electrodes 110 and 111 of the first polarity sensing electrode module 11 to form a power circuit. In addition, the positive electrode terminal 171 is also connected to the resistance processing sensing electrode 151 of the resistance processing sensing electrode module 15. Since the first polarity sensing electrodes 110 and 111 and the resistance processing sensing electrode 151 are connected to the positive terminal 171, the first polarity sensing electrodes 110 and 111 and the resistance processing sensing electrode 151 have a plurality of positive charges P1. The workpiece 2 relative to the surfaces (non-machined surfaces) 203 and 205 of the first polarity sensing electrodes 110 and 111 and the processing resistance sensing electrode 151 with positive charge P1 will induce a plurality of induced negative charges N2, so the surface of the workpiece 2 (Non-machined surface) 203 and 205 will generate these induced negative charges N2, so the surface 203 and 205 of the workpiece 2 is equivalent to the cathode of electrochemical machining without being dissolved. As can be seen from the above, the first polarity sensing electrodes 110 and 111 can also protect the non-machined surface of the workpiece 2.
由上述說明可知，本發明之感應式電化學加工裝置1利用感應方式於工件2之欲加工表面（下部位表面201）產生感應正電荷P2，使欲加工表面為陽極，而工件2之非加工表面（上部位表面203與下端面205）可產生感應負電荷N2，使非加工表面為陰極，如此電解液供應至工件容置空間100而進行電化學加工時，工件2之下部位表面201即會進行移除加工，而上部位表面203與下端面205則可以受到保護。如此可知，運用本發明之感應式電化學加工裝置1對工件2進行電化學加工時，工件2不需要與電極接觸，而可降低深色鈍化膜形成於工件2之表面的機率。As can be seen from the above description, the inductive electrochemical machining device 1 of the present invention uses an induction method to generate an induced positive charge P2 on the surface (lower surface 201) of the workpiece 2 to make the surface to be processed an anode, while the workpiece 2 is not processed The surface (upper surface 203 and lower end surface 205) can generate an induced negative charge N2, making the non-machined surface a cathode, so that the electrolyte is supplied to the workpiece receiving space 100 for electrochemical processing, the surface 201 of the lower part of the workpiece 2 is Removal processing is performed, and the upper surface 203 and the lower end surface 205 can be protected. Thus, it can be seen that when the induction-type electrochemical machining device 1 of the present invention is used to electrochemically process the workpiece 2, the workpiece 2 does not need to be in contact with the electrode, and the probability of the dark passivation film being formed on the surface of the workpiece 2 can be reduced.

In addition, the input ports 313 and 314 of the electrolyte input flow path of the first housing 31 also communicate with the workpiece accommodating space 100. The input ports 333 and 334 and the output ports 335 and 336 of the electrolyte output flow path of the second housing 33 are also connected to the workpiece accommodating space 100, which means that the electrolyte input flow path is indirectly connected to the electrolyte output flow path.
另外，外殼3具有一工件輸送通道300，其連通於第一殼體31之工件入口311與第二殼體33之工件出口331，而穿過第一殼體31、第二殼體33、此二個第三殼體35與第四殼體37。工件輸送通道300連通於電解液輸入流道、工件容置空間100與電解液輸出流道。In addition, the housing 3 has a workpiece conveying channel 300, which communicates with the workpiece inlet 311 of the first casing 31 and the workpiece outlet 331 of the second casing 33, and passes through the first casing 31, the second casing 33, Two third casing 35 and a fourth casing 37. The workpiece conveying channel 300 communicates with the electrolyte input flow path, the workpiece accommodating space 100, and the electrolyte output flow path.
於進行電化學加工時，藉由第一殼體31之電解液輸入流道之輸入口313、314提供電解液至工件容置空間100，且藉由第二殼體33之電解液輸出流道之輸出口335、336輸出電解液至外部電解液儲存槽（圖未示）。工件2由第一殼體31之工件入口311進入外殼3，並沿著工件輸送通道300往第二殼體33之工件出口331移動。於進行電化學加工之過程，工件2經工件容置空間100時，工件2之非加工表面可對應第一極性感應電極模組11與阻加工感應電極模組15之正電荷產生感應負電荷而為陰極，工件2之加工表面會對應第二極性感應加工電極模組13之負電荷產生感應正電荷而為陽極，如此第二極性感應加工電極模組13即會對工件2之加工表面進行電化學加工，而工件2之非加工表面即可受到保護。When performing electrochemical machining, the electrolyte is supplied to the workpiece accommodating space 100 through the input ports 313 and 314 of the electrolyte input flow path of the first casing 31, and the electrolyte output flow path of the second casing 33 is used The output ports 335 and 336 output electrolyte to an external electrolyte storage tank (not shown). The workpiece 2 enters the housing 3 from the workpiece inlet 311 of the first housing 31 and moves along the workpiece conveying channel 300 to the workpiece outlet 331 of the second housing 33. During the process of electrochemical machining, when the workpiece 2 passes through the workpiece accommodating space 100, the non-machined surface of the workpiece 2 can correspond to the positive charge of the first polarity sensing electrode module 11 and the resistive machining sensing electrode module 15 to generate a negative charge. As the cathode, the processing surface of the workpiece 2 will generate a positive charge corresponding to the negative charge of the second polarity induction machining electrode module 13 and become the anode, so that the second polarity induction machining electrode module 13 will electrify the machining surface of the workpiece 2 Learn to machine, and the non-machined surface of the workpiece 2 can be protected.
復參閱第一B圖與第四圖，第二極性感應加工電極模組13之第二極性感應加工電極130、131之側面為一斜面，其相對於工件容置空間100，也相對於工件2之加工表面，此斜面與工件容置空間100之間距係沿工件出口331之方向而逐漸變小，即此斜面與工件2之間距d沿工件出口331之方向而逐漸變小，其表示斜面與工件2之間會形成一楔形流道，如此電解液流經此楔形流道時，其流速會隨著斜面與工件2之間距d逐漸變小而逐漸增加。第二極性感應加工電極130、131對工件2進行電化學加工之過程會產生加工生成物，而加工生成物會朝電解液之流動方向（電解液輸出流道之輸出口333、334與工件出口331之方向）而逐漸累積，如此電導率會逐漸遞減。藉由楔形流道可以逐漸增加電解液之流速，而可以增加帶離加工生成物之速度，如此讓第二極性感應加工電極130、131對整體工件2之加工速度可以趨近於一致，而提高加工品質。Referring back to FIGS. 1B and 4, the sides of the second polarity induction machining electrode modules 13 and 130 of the second polarity induction machining electrode module 13 are inclined surfaces, which are relative to the workpiece accommodating space 100 and also to the workpiece 2 The processing surface, the distance between the inclined surface and the workpiece accommodating space 100 gradually decreases along the direction of the workpiece outlet 331, that is, the distance d between the inclined surface and the workpiece 2 gradually decreases along the direction of the workpiece outlet 331, which indicates that the inclined surface is A wedge-shaped flow channel is formed between the workpieces 2, so that when the electrolyte flows through the wedge-shaped flow channel, its flow rate will gradually increase as the distance d between the inclined surface and the workpiece 2 gradually decreases. The process of the electrochemical machining of the workpiece 2 by the second polarity induction processing electrodes 130 and 131 will produce processing products, and the processing products will be directed toward the flow direction of the electrolyte (the output ports 333, 334 of the electrolyte output flow path and the workpiece outlet 331 direction) and gradually accumulate, so the conductivity will gradually decrease. The wedge-shaped flow path can gradually increase the flow rate of the electrolyte, and can increase the speed of the product away from the processing, so that the processing speed of the second polarity induction processing electrode 130, 131 on the entire workpiece 2 can be close to the same, and increase Processing quality.
同於上述，第一感應電極模組11之第一感應電極110、111之側面亦可為斜面，其相對於工件容置空間100，也相對於工件2之非加工表面，此斜面與工件2之間距沿工件出口331之方向而逐漸變小。Similar to the above, the side surfaces of the first sensing electrodes 110 and 111 of the first sensing electrode module 11 may also be inclined surfaces, which are relative to the workpiece accommodating space 100 and also to the non-machined surface of the workpiece 2, the inclined surface and the workpiece 2 The distance gradually decreases along the direction of the workpiece exit 331.
