[Industrial Application Field] This invention relates to a method for manufacturing an electrically insulated conductor,
In particular, the present invention relates to a method of manufacturing an electrically insulated conductor, in which a mica insulating film is formed by electrodeposition on a conductor forming a rotating machine coil for a vehicle. [Prior Art] First, the principle of electrodeposition will be explained. An electrodeposition solution made by adding water to mica powder, which is normally negatively charged in water, and water-dispersed varnish, which is also negatively charged, is placed in an electrodeposition bath, and a conductor to be electrodeposited is immersed in the electrodeposition solution to serve as an anode. When a DC voltage is applied using the electrodeposition tank as a cathode,
An electrodeposited layer containing mica powder as a main component is formed on the surface of the electrodeposited object. Here, the water-dispersed varnish is used to increase the adhesive strength between the mica powders. As a conventional manufacturing method for electrically insulated conductors,
The first method disclosed in Japanese Patent No. 58-53967 will be explained with reference to FIG. In FIG. 2, a nozzle 2 is provided in an electrodeposition bath 1 facing a conductive electrodeposited object 3, and an electrodeposition liquid 4 is circulated by first and second pumps 5, 6. 7 is a turning plate. This method requires a main flow P for circulating the electrodeposition liquid 4 at a constant speed and a stirring flow Q for stirring the electrodeposition liquid 4, and also requires two sets of devices for circulating the electrodeposition liquid 4. Here, if the electrodeposited object 3 is a hexagonal conductor, the film thickness will be uneven between the surface facing the flow of the electrodeposition liquid 4 and the shaded part, which will slow down the progress of electrodeposition. At an intermediate point, temporarily stop applying the DC voltage and align the electrodeposited object 3 with respect to the vertical line.
The electrodeposited material 3 is rotated 180 degrees and electrodeposited again, and after the electrodeposition is completed, the object 3 to be electrodeposited is rotated 180 degrees again and returned to its original position.
Therefore, if the time required for electrodeposition is T4 , the first half electrodeposition time is T2 , the second half electrodeposition time is T3 , and the rotation time is T5 , then T4 = T2 + T3 + 2・T It becomes 5 . In addition, as a conventional method for manufacturing electrically insulated conductors,
There is a second method disclosed in Japanese Unexamined Patent Publication No. 158808/1983, which will be explained with reference to FIG. In FIG. 3, a discharge nozzle 9 is provided in an electrodeposition tank 8 having a tapered bottom surface. , an inflow pipe 12 is provided. Then, the electrodeposition liquid 4 enters the electrodeposition tank 8 from the discharge nozzle 9 and circulates at a low speed. Next, the electrodeposition liquid supply system consisting of the overflow pipe 11 and the inflow pipe 12 has the function of supplying the electrodeposition liquid 4 consumed during electrodeposition and keeping the level of the electrodeposition liquid constant. If this device is used, the mica powder will not settle at the bottom of the electrodeposition tank 8, the electrodeposition solution 4 will circulate at a low speed, and the mica powder will be uniformly distributed in the electrodeposition tank 8, so that it will not be exposed to the mica powder when DC voltage is applied. A uniform film can be obtained without rotating the electrodeposited material. [Problems to be Solved by the Invention] In the first method, the conventional method for producing an electrically insulated conductor as described above involves temporarily stopping the application of DC voltage at each intermediate stage of electrodeposition. The extra steps of rotating the kimono 180° and then rotating the electrodeposited object again after the electrodeposition is completed are necessary, so if this method is applied to a production line for mass production, there will be a lot of wasted time, which will reduce productivity. In addition, there were other problems such as the speed control of the main flow of the electrodeposition solution and the stirring flow was complicated. In addition, in the second method, although precipitation of mica powder can be prevented by the tapered shape of the bottom of the electrodeposition tank, strictly speaking, the distribution of mica powder cannot be said to be uniform in each part of the electrodeposition tank. When electrodepositing a relatively large hexagonal conductor, the film thickness will be non-uniform, and if the electrodeposition is performed so that the part where it is most difficult to form a film has a thickness greater than the set thickness, other parts of the conductor may Since an extra thick film is formed on the parts, if a coil is made by combining these electrodeposited conductors, the dimensions will be larger compared to the coil made by the first method, and it will not fit inside the rotating machine slot. The problem was that the space factor deteriorated, which became one of the factors that made it difficult to reduce the size and weight of rotating machines. This invention was made to solve these problems, and it not only shortens the time required for electrodeposition and improves productivity, but also makes it easier to control the speed of the electrodeposition solution, and to achieve a layered and uniform film thickness. The purpose of the present invention is to obtain a method for producing an electrically insulated conductor that enables the production of a compact coil by forming an electrodeposited film, improves the space factor, and reduces the size and weight of a rotating machine. [Means for Solving the Problems] The method for manufacturing an electrically insulated conductor according to the present invention allows the electrodeposition liquid in the electrodeposition tank to flow vertically downward from the liquid level, and also prevents the conductor from being covered when a DC voltage is applied. The electrodeposited material is reciprocated in the horizontal direction to increase the relative speed between the conductor and the electrodeposition liquid, and the mica powder is deposited on the surface of the conductor in a layered manner and with a uniform thickness. [Function] In this invention, the total time required for electrodeposition is reduced.
If T 1 [sec.] is the time to move the conductor in one direction while applying a DC voltage, T 2 [sec.] is the time to move the conductor in the opposite direction, and T 3 [sec.] is the time to move the conductor in the opposite direction, then T 1 = T2 + T3
It is expressed as On the other hand, in the first conventional method, the conductor must be rotated by a certain angle at the intermediate point of electrodeposition, and the rotation time is T 4 [sec.], and the total time required for electrodeposition in the conventional method is T 5 [sec.]. .], then T 5 = T 2 + T 3 + 2・
Therefore, T 1 < T 5 . Furthermore, in order to control the flow rate of the electrodeposition liquid in this invention, while the electrodeposition liquid in the electrodeposition bath is flowing vertically downward from the liquid surface at a low speed, the conductor is reciprocated in the horizontal direction when a DC voltage is applied. Since the method uses a method of increasing the relative speed of the conductor and the electrodeposition liquid, the reciprocating speed of the conductor can replace the conventional control of the flow rate of the electrodeposition liquid, allowing fine-grained speed control and setting the optimal conditions. can. [Embodiment] An embodiment of the present invention will be described below with reference to FIG. In FIG. 1, a slide base 14 is connected via a hydraulic cylinder 15 to a lifting device 13 provided on the side of an electrodeposition bath 8 having a tapered bottom surface. The electrodeposited object 3 is suspended and supported by a support rod 17 via a hanging tool 16. In addition, the same reference numerals as in FIG. 3 indicate the same parts. With the above-described apparatus, first, the electrodeposition liquid 4 enters the electrodeposition tank 8 from the discharge nozzle 9, and is circulated through the suction hole 10, through the electrodeposition liquid circulation pump, and back to the discharge nozzle 9. Further, the electrodeposition liquid supply system consisting of the overflow pipe 11 and the inflow pipe 12 replenishes the electrodeposition liquid 4 consumed during electrodeposition and maintains the level of the electrodeposition liquid at a constant level. When the conductive electrodeposited object 3 is set at a fixed position on the support rod 17 together with the hanging tool 16, the lifting device 13 that operates in the direction of arrow B is lowered, and the conductive electrodeposited object 3 is placed in the electrodeposition liquid 4. immersed in. Next, a DC voltage is applied between the electrodeposited conductor 3 as an anode and the electrodeposition tank 8 as a cathode, and at the same time, the hydraulic cylinder 15 is actuated to apply electricity to the slide base 14 and the conductor connected thereto. The kimono 3 is caused to reciprocate in the horizontal direction indicated by arrow A in the electrodeposition tank 8, and when the electrodeposition is completed, the elevating device 13 is raised to take out the electrodeposited object 3 from the electrodeposition tank 8. In the above manufacturing method, the average moving speed of the reciprocating movement of the electrodeposited object 3 during application of DC voltage is 1.2 m/
A range of min to 12 m/min is preferred. If the moving speed is higher than this range, the film thickness will be uneven due to the influence of vortices generated in the shadow part against the flow in the moving direction, and if the moving speed is lower than the above range, the effect of the reciprocating motion of the conductor will be less and the film thickness will be uneven. The thickness becomes uneven.
Further, the number of times F of this reciprocating movement may be any number as long as it is one or more times, but the reciprocating movement is set based on the electrodeposition time T, the dimensions of the electrodeposited object 3, and the dimensions of the electrodeposition tank 8. It is determined by the following equation from the relationship between the stroke L and the moving speed V. F=V・T/L The average flow velocity of the electrodeposition liquid 4 in the vertical downward direction is 0.5 m/
A value of min or more is preferable. If the average flow velocity is lower than this, the distribution of mica powder will be uneven, and the film formed after electrodeposition will also vary. Further, although there is no particular restriction on the maximum value of the flow velocity, increasing the flow velocity only unnecessarily increases equipment costs and power consumption, and there is no benefit at all. Table 1 below provides data for various examples.

As is clear from the above description, this invention
By causing the electrodeposition liquid in the electrodeposition tank to flow vertically downward from the liquid surface at low speed, and by moving the electrodeposited object back and forth in the horizontal direction when a DC voltage is applied, the relative velocity between the electrodeposition object and the electrodeposition liquid is increased. In addition, the electrodeposition time is shortened and productivity is improved, and the speed of the electrodeposition solution is easily controlled.Also, the mica powder is layered and uniform on the surface of the electrodeposited object electrodeposited in this way. Since the film is deposited with a certain thickness, there is no extra film pressure on each part of the electrodeposited material, and the dimensions of the coil made by combining several electrodeposited materials become compact, improving the space factor. Rotating machines that use coils can be made smaller and lighter.
