る。2. Description of the Related Art FIG. 5 shows a conventional V-type engine cylinder plating apparatus using an anode electrode for electroplating. This conventional electroplating anode rod 19 has a straight rod shape,
The upper ends of the anode rods 19 that are not inserted into the cylinder 6 are connected to each other by an anode plate 7. The plating jig 4 is for placing the cylinder 6, which is the object to be plated, on a horizontal surface and mounting the cylinder in a stable posture. When the cylinder 6 and the main body of the plating jig 4 of the V-type engine are connected to the cathode and the anode plate 7 and the anode rod 19 are connected to the anode, the engine cylinder 6 is plated when electricity is applied.

る。However, since the conventional anode rod 19 has a straight rod shape, the upper end of the two anode rods 19 which are not inserted into the cylinder 6 is wide and the anode plate 7 is long. Will end up. Therefore, the energization distance becomes long and the electrical loss becomes large. Moreover, since the weight of the plating jig 4 is large, the load during work and the load on the vibration motor are large. Moreover, since the lateral protrusion is large, the width of the entire plating jig 4 is large. Therefore, a large-sized plating tank is required, which requires equipment cost and plating solution cost.

生じるなどの不都合がでてしまう。In the case of stirring by vibration, if the anode plate and the anode rod are immersed in the plating solution, there is a risk of short-circuiting between them and the portion to be plated, which may cause defective plating. Further, in particular, when the plating solution is applied to the portion where the upper end of the anode rod 19 and the anode plate 7 are in contact with each other, the metal is eluted, so it is necessary to avoid submerging the upper end of the anode rod 19 and the anode plate 7.
In the conventional anode rod 19, since the electric contacts such as the anode plate 7 are easily submerged in the plating solution during processing, the vibration distance cannot be increased. On the other hand, if the total length of the anode rod 19 is increased to increase the vibration distance, the tip of the plating solution rises and the risk of submersion in water decreases. However, the width becomes larger accordingly, and the plating tank needs to be made larger.

If there is a gap between the nickel particles 18 or the packing density is uneven when the nickel particles 18 are filled, there is a disadvantage that the current is not stable and uneven plating or uneven film thickness occurs. As shown in FIG.
In the conventional anode rod, since the direction of filling the nickel particles 18 and the direction of gravity applied to the nickel particles 18 are different, it is not possible to effectively use the gravity, and a gap is formed between the nickel particles 18, or a deviation of the packing density occurs. Cheap.

り、振動モーターへの負荷も小さくなる。According to the present invention, by bending the anode rod as described above, the distance between both ends of the two anode rods which are not inserted in the cylinder is narrowed and the length of the anode plate is shortened. Therefore, electrical loss can be reduced. Furthermore, since the weight of the plating jig is reduced, the work load is lightened and the load on the vibration motor is also reduced.

減できる。Further, as shown in FIG. 3, by bending the anode rod 1 as described above, the gap between the upper ends of the two anode rods becomes smaller as compared with the conventional anode rod 19, so that the plating is performed. The width of the entire jig 4 can be reduced. for that reason,
The plating tank can also be downsized, and equipment costs and plating solution costs can be reduced.

The protrusion of the tip from the plating solution is higher than that.
Therefore, when the plating jig is vertically vibrated during plating, the risk of the anode plate and the anode rod being submerged in the plating solution is reduced. Therefore, it is possible to sufficiently stir the vibration with a large vibration width, and to perform the plating more uniformly.

とはない。Further, as shown in FIG. 4, the anode rod 1 of the present invention is bent vertically upward as described above, so that the filling direction of the nickel particles 18 and the direction of gravity are the same. Therefore, the gravity applied to the nickel particles 18 can be effectively used. The anode rod of the present invention is made of nickel particles 18
When nickel is dissolved and becomes smaller as the plating progresses, the nickel particles 18 are sequentially and smoothly filled downward without forming gaps between the nickel particles 18 and uneven filling density. Therefore, the current flows stably, and there is no inconvenience such as uneven plating and uneven film thickness.

省電力が可能となる。When the anode rod of the present invention is bent vertically upward, the resistance received from the plating solution is reduced when the plate is vibrated vertically and stirred, so that the vibration motor can be downsized and the power consumption can be saved.

保てる。When stirring with air, the bubbles rise upward from the lower part of the plating tank, and part of them pass through the inside of the anode rod. However, since air has an insulating property, it is not preferable that it exists in the anode rod in terms of electrical conductivity. When the anode rod of the present invention is bent vertically upward, bubbles can easily escape upward, and good electrical conductivity can be maintained.
