Description of the invention (() Field of invention (please read the precautions on the back before filling out this page) This invention is about applying electrolytic surface treatment such as electrolytic cleaning or electrolytic honing on the wire Wire electrolysis treatment method and wire electrolysis treatment device. BACKGROUND OF THE INVENTION For the technology of applying electrolytic surface treatment such as electrolytic honing or electrolytic honing, the use of pipe-type elements in electrolytic pickling equipment is a Japanese patent. The invention described in -43795 or Japanese Patent Laid-Open No. 2-47291. For this type of technology, the bipolar phenomenon is known, and it is known to have excellent electrolysis that can be reversed on the way. PR electrolysis method The electrolysis treatment device used in the PR electrolysis method is, for example, as shown in FIG. 6, and a pair of tubular electrodes 10 are vertically aligned and connected through an insulating joint portion 20, and are connected to each electrode. It is connected to the anode and cathode of each power source 40. In the tubular electrode, the electrolytic treatment liquid supplied from the tank 60 is pumped by the pump 61, and the wire is electrolyzed to make The material 100 travels in the direction of the bearing. However, the conventional technique described above has the following problems. (1) Because the leakage current of the polarity conversion unit is large, the ratio of the input current to the electrolytic treatment changes. The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed in the joint part constituting the polarity conversion unit, because the electrolytic treatment liquid in the cathode tube and the electrolytic treatment liquid in the anode tube have to be separated, so that the Current flows (leakage current). For this reason, the ratio of the electrolytic treatment in the input current is reduced, and the current loss cannot be increased too much. (2) It is difficult to make soft wires, wires with poor straightness, Or 4 paper bearing standards apply Chinese National Standard (CNS) A4 specification (210 X 297 mm) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 567251 A7 9189pif.doc / 〇〇8 β7 5. In the description of the invention (2) A wire with a smaller diameter passes through the tube. When the processing capacity is improved, the tubular electrode is preferably developed to be smaller and longer. Among them, it is difficult to make soft wires and poor straightness. (Strong crimping) thread or a thread with a small inner diameter must pass through, so it is necessary to use a jig such as an introduction rod. (3) It is not easy to change the polarity ratio and the number of polarity conversions. In conventional equipment, Because the number of electrodes and electrode length must be designed in advance, it is impossible to change the number of polarity conversions or the electrode length ratio according to the situation. (4) It is difficult to control the travel position of the wire. The entire periphery of the wire During the electrolytic treatment, the wire must be in the center of the tubular electrode in order to pass it uniformly. In the conventional method, the vibration of the wire, the relaxation of the wire, and the movement of the treatment liquid will cause it to shift from the center. As a result, the processing amount on the side closer to the electrode becomes larger, and the processing amount on the opposite side becomes smaller, thereby causing the processing amount in the peripheral direction to be uneven. Furthermore, there is a fear that the offset between the contact between the electrode and the wire becomes large. Increasing the tube length also increases the risk of uneven handling or contact with the electrodes. Invention 槪 沭 Therefore, one of the objects of the present invention is to provide a method for the electrolytic treatment of wire rods to eliminate the leakage current which does not help the electrolytic treatment of the wire rods. Furthermore, "another object of the present invention is to provide a wire electrolysis treatment device" to eliminate the leakage current which does not contribute to the electrolysis treatment of the wire. In order to achieve the above-mentioned object, the present invention is a tube arranged in a straight line. The paper size is applicable to the Chinese national standard (please read the precautions on the back before filling this page) II Order! !! -Line 1 567251 Printed by A7 918 9pi f.doc / 008, Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 5. Description of the Invention (々) Use insulating shields between the electrodes to prevent them from being trapped inside the tubular electrode tubes. The circulation of the electrolytic treatment liquid reduces the leakage current which is not helpful to the electrolytic treatment. That is, the present invention provides a wire electrolysis treatment method, which is suitable for arranging tubular electrodes of different polarities in an array, supplying an electrolytic treatment liquid in the electrodes, and performing electrolysis treatment on the surface of the wire by the PR electrolysis method while the wire is traveling This method includes: providing a shielding plate with an insulation system between the electrodes, the shielding plate is used to limit the flow of electrolytic treatment liquid and prevent leakage current between the electrodes. Furthermore, the present invention proposes a wire electrolysis treatment device, which includes a plurality of tubular electrode 'supply mechanisms, a travel mechanism, a joint portion of an insulation system, and a shield plate of the insulation system. An electrolytic treatment chamber is provided inside the plurality of tubular electrodes. The supply mechanism supplies an electrolytic treatment liquid into the electrolytic treatment chamber.

Description of the invention (Heart) Separation structure. The length of each tubular electrode is preferably 500 mm or less. When the length of the electrode is 500 mm or more, it is difficult to obtain the effect of preventing line vibration through the center hole of the shielding plate, and the possibility of uneven treatment or contact between the electrodes is further increased. Furthermore, even in a long tube having a size of 500 mm or more, switching effects such as the polarity order, the number of polarity transitions, the effective electrode length, and the electrode length of each electrode region cannot be obtained. In short, the tube length L and the tube inner diameter d are preferably L / d < 20. When L / d is 20 or more, only the degree of uneven processing of the line becomes large. The center portion of the shielding plate of the insulation system is preferably formed with a through hole for wire travel, and the area of the through hole A (mm2) and the inner diameter d (nim) of the wire is preferably (Α / τΓ) 1 / 2-d / 2 $ 5. "(Α / ΤΓ) 1 / 2-d / 2 $ 5" means the average distance between the inner surface of the insertion hole and the surface of the wire. When it exceeds 5 mm, the restraint force of the wire toward the center of the electrode becomes weak, which causes the uneven treatment such as wire vibration. In the above description, the processing method and processing apparatus of the present invention can also obtain the following effects. The treatment liquid connected to electrodes with different polarities can be separated by the shielding plate in the joint, so that the leakage current lost by the current passing through the treatment liquid can be minimized, and the energy loss can be reduced, effectively. Perform electrolytic treatment. Since the leakage current between the processing liquids is reduced, it is possible to suppress the occurrence of gas due to the decomposition of the processing liquid, thereby reducing the overheating of the processing liquid and suppressing the deterioration of the liquid. 7 This paper size applies to China National Standard (CNS) A4 (210x 297 mm) (Please read the precautions on the back before filling this page) Printed by the employee consumer cooperative 567251 A7 9189pif.doc / 008 37 V.

The insertion holes can also be circular. For the uniformity of the spacing between the electrode 10 and the wire, the preferred shape is a circle, a regular polygon, or a symmetrical shape on each side. The area of the wire is not necessarily larger than the cross-sectional area of the wire. When the area of the insertion hole is small, the position of the wire that vibrates in the radial direction of the tubular electrode due to the vibration of the wire, the relaxation of the wire, and the flow of the liquid is suppressed.

In addition, the treatment liquid is brought into effective contact with the wire, and the liquid is prevented from being deteriorated. (End Pressing Portion) End pressing portions 50 are attached to both end portions of the tubular electrodes 10 connected in-line. The end pressing portion 50 may be made of the same material as the joint portion. That is, it is preferable that the tubular electrode 10 is inserted only on one end side of the joint portion 20 and no tubular electrode is arranged on the other end side. One of a supply hole and a discharge hole for the processing liquid may be provided thereon. (Supply mechanism) The supply mechanism of the electrolytic treatment liquid includes a tank 60 for storing the treatment liquid, a pump 61 for circulating the treatment liquid, and a connection pipe 63 for supplying the treatment liquid to the joint portion 20. In the treatment liquid, various electrolytes can be used depending on the object or purpose of the treatment. For example, hydrochloric acid can be used in the pickling process.

Therefore, the necessary current density required in actual electrolytic pickling is higher than this. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs in the above, in the example of the present invention, ① the distance between the electrode and the wire can be reduced; ② the leakage current between the plates of the polarity conversion unit can be reduced; ③ better treatment Effects such as contact between liquid and wire, and because the size of the paper is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 567251 A7 9189pif.doc / 008 B7 V. Description of the invention (㈧) Shortened installation length With high line speed, the same effect as low input power can also be obtained. Further, in the comparative example, since the processing amount in the peripheral direction is not uniform and the contact current between the wire and the electrode decreases the processing current instantaneously, more processing is required. On the other hand, in the example of the present invention, the processing amount is not uneven in the peripheral direction, and the contact between the wire and the electrode does not occur. In addition, in the comparative example, after continuous processing at 100 units of time due to accumulation of mud or deterioration of the liquid, its processing capacity will be greatly reduced, and it is necessary to perform sweeping in the tube and renewal of the electrolytic treatment liquid. However, in the example of the present invention, the processing capacity is not reduced even after continuous processing is performed at 150 unit times.
