And the correction members 40 and 40 disposed in 30. The support member 30 is bifurcated at the tip side, and a substantially L-shaped electrode 32 is disposed at each tip, so that the resist processing is not performed on the two attachment portions 13 and 13 near the center. By locking and bringing the electrodes 32 and 32 into contact with the site, the base material 10 can be supported in the plating bath 46 and energized. Further, the correction members 40, 40 provided on both sides of the support member 30 so as to extend in the horizontal direction are rod-shaped members capable of elastic deformation, having a hook-shaped portion 42 formed at the tip thereof.

The lower lateral restriction portion 65B is opposed to the lower end surface of the base material 10 in the short direction of the locking portion 13B. . In addition, the vertical frame member 62 in which the second fixing portion 65 is formed is separated between the upper and lower horizontal regulating portions 65B and 65B of the second fixing portion 65.

The correction member 60 formed in a frame shape in this way is formed to be higher in rigidity than the base material 10, and as shown in FIG. 3, the space-side outer surface of the vertical restricting portion 64 </ b> A of the first fixing portion 64 and the second surface. In the base material 10 in which the distance L in the longitudinal direction of the straightening member 60 from the empty side outer surface of the vertical restricting portion 65A of the fixing portion 65 is a specified shape (the final product shape of the plating member M), the base material 10 It is set to be the same as the distance W between the side end surfaces of the locking portions 13B of the mounting portions 13 and 13 located near both ends in the longitudinal direction. Therefore, the correction member 60 can be mounted with the base material 10 corrected to a specified shape, and can hold the base material 10 in a specified shape. Moreover straightening member 60, the rigidity than the base material 10 is made higher rather form, it is not easily deformed even when used for the surface treatment of a number of the base member 10. The correction member 60 includes the first fixing portion 64 in the vertical frame member 62 in which the first fixing portion 64 and the second fixing portion 65 that are in contact with the locking portion 13B of the mounting portion 13 and the first fixing portion 64 are disposed. The portion where the second fixing portion 65 is provided, the portion where the second fixing portion 65 is provided in the vertical frame member 62 where the second fixing portion 65 is provided, and the pin 66 are subjected to resist processing in advance. Therefore, the correction member 60 is not energized at the time of surface treatment because the portion that comes into contact with the base material 10 is subjected to resist processing, and the horizontal frame members 61 and 61, the vertical frame members 62 and 62, the reinforcing frame member 63, and the first fixing portion. 54, the second fixing portion 65 and the pin 66 are not formed with the plating film 20.

Is attached to the rear side of the base material 10 as shown in FIGS. 4 and 5. At this time, if the base material 10 is deformed from the prescribed shape, the pin 66 is inserted and locked in the through hole 15 and the second fixing portion 65 is engaged with the locking portion 13B of the corresponding mounting portion 13. When the base member 10 is stopped, the corrective member 60 and the base member 10 can be mounted by appropriately deforming the base member 10 and aligning the locking portions 13B of the corresponding mounting portions 13 with the first fixing portions 64. Become.

  Next, the manufacturing method of the plating member M using the plating apparatus U of the Example comprised as mentioned above is demonstrated.

  In the manufacturing method of the embodiment, as shown in FIG. 3, as a first work stage, the correction member 60 is attached to the base material 10 before being attached to the support member 50. That is, when the base material 10 has been deformed from the specified shape, first, the pin 66 is inserted and locked in the through hole 15, and then the locking portion 13 B of the corresponding mounting portion 13 is connected to the second fixing portion 65. Then, the first fixing portion 64 is inserted into the first fixing portion 64 while the base material 10 is appropriately deformed, and the corresponding locking portion 13B of the mounting portion 13 is inserted into the first fixing portion 64 so as to be corrected on the back side of the base material 10. The member 60 is attached. As a result, the vertical restricting portion 64A of the first fixing portion 64 and the vertical restricting portion 65A of the second fixing portion 65 are engaged with the engaging portions 13B of the attachment portions 13 and 13 that are located near both ends in the longitudinal direction of the base material 10. Therefore, the base material 10 and the correction member 60 are prevented from shifting in the longitudinal direction of the base material 10. In addition, each lateral restricting portion 64B of the first fixing portion 64 and each lateral restricting portion 65B of the second fixing portion 65 are each locking portion of the attachment portions 13 and 13 that are located near both ends in the longitudinal direction of the base material 10. Since the upper end surface and the lower end surface of 13B are in contact with each other, the base material 10 and the correction member 60 are also prevented from being displaced in the short direction of the base material 10. Accordingly, the base material 10 is restricted to twisting deformation in the longitudinal direction, bending deformation in the short direction, bending deformation in the front and back directions, etc., and is corrected to a specified shape (the final product shape of the plated member M) and specified. It is held in the shape of

  Next, as a second work stage, as shown in FIG. 4, the base material 10 on which the correction member 60 is mounted is supported by the electrodes 53 and 53 of the support member 50. That is, the electrode 53 of the first lateral support portion 52A of the support member 50 is engaged with the beam contact portion 13A of the one attachment portion 13 in the two attachment portions located in the middle of the base material 10 to contact the electrode contact portion 13C. At the same time, the electrode 53 of the second lateral support portion 52B of the support member 50 is engaged with the beam portion 13A of the other attachment portion 13 of the two attachment portions located in the middle of the base material 10 to be the electrode contact portion 13C. Contact. As a result, the base material 10 on which the correction member 60 is mounted is supported without dropping off from the support member 50, and the electrodes 53 and the mounting portions 13 are electrically connected to each other (FIG. 5). reference).

  Next, as a third work stage, as shown in FIGS. 1 and 2, the support member 50 that supports the base material 10 is immersed in a plating bath 71 stored in a plating tank 70, and the conductive mother An external power source is applied to the base material 10 so that the material 10 becomes a cathode and is energized. As a result, the metal ions dissolved in the plating bath 71 are reduced on the surface 11 and the outer peripheral surface 12 of the base material 10 supported by the correction member 60 in a defined shape, and the surface 11 and the outer peripheral surface 12 are not subjected to resist treatment. The plating film 20 begins to be formed. When the required processing time elapses, the plating member M in which the plating film 20 having the required thickness is formed on the surface 11 and the outer peripheral surface 12 is formed. Since the pin 66 is inserted into the through hole 15 of the wall portion 14, the through hole 15 is not blocked by the plating film 20 during the plating process.

  Therefore, according to the manufacturing method of the plating member M of the embodiment, the base material 10 is deformed without deforming the correction member 60 and the base material 10 is held by the rigid correction member 60. The deformation of 60 can be suppressed and the accuracy of the correction member 60 can be maintained. That is, the correction member 60 is not easily deformed even when used over a long period of time, and can stably correct the base material 10 before the surface treatment into a predetermined shape. Further, since the correction member 60 and the support member 50 are configured separately, the correction member 60 is not affected by the accuracy of the support member 50. Since the base material 10 having conductivity having a prescribed shape is supported by the support member 50 and the surface treatment is performed, the surface 11 and the outer peripheral surface 12 of the base material 10 which are not subjected to the resist treatment have a required thickness. The plating film 20 can be formed. Since the plating member M on which the plating film 20 is formed has a constant size and shape, the occurrence rate of product defects is greatly reduced, product management is facilitated, manufacturing efficiency is improved, and manufacturing cost is increased. Can be reduced.

  Further, in the manufacturing method of the embodiment, the attachment portions 13 and 13 positioned near both ends in the longitudinal direction held by the first fixing portion 64 and the second fixing portion 65 of the correction member 60 in the base material 10 are plated coatings. Since the resist treatment that cannot be formed is applied in advance, the plating film 20 is prevented from being formed on the attachment portion 13, and the base material 10 and the correction member 60 can be easily separated after the surface treatment. it can. Further, when the base material 10 and the correction member 60 are separated, the plating film 20 is not scratched or damaged. In addition, the electrodes 53 and 53 that form part of the first lateral support portion 52A and the second lateral support portion 52B of the support member 50, and the beam portions 13A of the two attachment portions 13 and 13 provided near the center of the base material 10. Since the contact between the electrode contact portion 13C provided on the beam portion 13A and the electrode 53 is simultaneously achieved, the conductive base material 10 can be energized via the electrodes 53 and 53. The operation of forming the plating film 20 on the surface 11 and the outer peripheral surface 12 of the base material 10 can be easily performed. Further, the electrodes 53 and 53 of the support member 50 are generated by the correction because they are only used to support the base material 10 that has been previously corrected to the required shape by the correction member 60 and are not used to correct the base material 10. It is possible to prevent the electrodes 53 and 53 from being broken or damaged due to the force applied to the electrodes 53 and 53.

  On the other hand, according to the plating apparatus U of the embodiment, the base material 10 is deformed without deforming the correction member 60, and the base material 10 is held by the rigid correction member 60. The deformation of the correction member 60 is suppressed, and the accuracy of the correction member 60 can be maintained. That is, the correction member 60 is not easily deformed even when used for a long time, and the base material 10 before the surface treatment can be stably corrected into a predetermined shape. Further, since the correction member 60 and the support member 50 are configured separately, the correction member 60 is prevented from being affected by the accuracy of the support member 50. Since the base material 10 having a predetermined shape and having conductivity is supported by the support member 50 and the surface treatment is performed, the surface 11 and the outer peripheral surface 12 of the base material 10 which are not subjected to the resist treatment are plated with a required thickness. The coating 20 can be formed. And since the plating member M in which the plating film 20 is formed is formed with a constant size and shape, the product defect rate is greatly reduced, product management is facilitated, and manufacturing efficiency is improved. Manufacturing costs can be reduced.

  In the plating apparatus U of the embodiment, the first fixing portion 64 and the second fixing portion 65 that hold the attachment portions 13 and 13 in the correction member 60 are subjected to resist processing in advance, and the plating film 20 is not formed. Therefore, the base material 10 and the correction member 60 can be appropriately separated after the surface treatment. Further, when the base material 10 and the correction member 60 are separated, the plating film 20 can be prevented from being damaged or damaged. Moreover, the plating apparatus U mounts the base material 10 and the correction member 60 using the mounting portion 13 used when mounting the plating member M to the headlight, and uses the mounting portion 13 to mount the base material 10. Since the material 10 is configured to be supported by the support member 50, it is not necessary to separately provide the base material 10 with a part for mounting the correction member 60 and a part for supporting the correction member 60. Therefore, the manufacturing cost of the plating member M is not increased, and the plating member M can be prevented from becoming heavy.

  Further, the plating apparatus U of the embodiment is configured so that the correction member 60 does not interfere with the support member 50 when the base material 10 on which the correction member 60 is mounted is supported by the support member 50. The base material 10 can be appropriately supported by the support member 50. Further, since the correction member 60 is formed in a frame shape, it can be configured to have higher rigidity than the base material 10 while preventing an increase in weight. Furthermore, since the base material 10 is configured to be supported by the electrodes 53 and 53 of the support member 50, the base material 10 is supported by the electrodes 53 and 53, and at the same time, the base material 10 can be energized. The operation of forming the plating film 20 on the surface of the base material 10 can be easily performed. Further, the electrodes 53 and 53 of the support member 50 are configured not to be used for correcting the base material 10 only by supporting the base material 10 that has been corrected in advance to a required shape by the correction member 60. Further, it is possible to prevent the electrodes 53 and 53 from being broken or damaged due to the force generated by the correction applied to the electrodes 53 and 53.
