Description

[Detailed description of the invention] The present invention relates to a hanger for plating.

Conventionally, as a hanger for plating, a concave shape of the same shape as the branch rod is provided on the main rod, and a bolt hole is provided close to the concave shape.
There was one in which a branch rod was fitted into this concave shape and then fixed with bolts and nuts (see No. 0-Mochiko Sho 40-3403).

By the way, in general, plating a complex-shaped object requires a plating hanger having an auxiliary anode.

Furthermore, when plating a large number of objects at once, for example, when the objects to be plated are small, a plating hanger with a large number of branch rods attached is required.

However, conventional hangers for plating require bolt holes, and even if bolt holes are not required, if the density of the branch rods is increased, the strength of the main rod will decrease and it will not be able to withstand long-term use. There is a drawback.

However, if a particularly thick main rod is used, it has the disadvantage that it cannot be used as a main rod for objects that have a simple shape, that is, for objects that require fewer branches.

An object of the present invention is to provide a plating hanger that eliminates these drawbacks.

The feature of the present invention resides in a plating hanger that is formed by aligning and fixing two or more main rods in which a plurality of branch rods are driven and fixed in parallel to each other.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial perspective view showing one embodiment of the plating hanger of the present invention. In the figure, 1 is a main rod made of copper, 2 is a branch rod made of stainless steel having a spring effect, and the center A bent portion 3 is formed in the portion.

The part of the branch rod 2 including this bent part 3 is placed on the main rod 1,
Strong pressure is applied from above to fix it to the main rod 1.

In this way, the branch rods 2 are successively fixed to the main rod 1 at approximately equal intervals or in accordance with the shape of the object to be plated.

The end portion 2a of the branch rod 2 is processed as appropriate depending on the shape of the object to be plated.

The two pieces of the main rod manufactured in this way are welded or otherwise combined into one body.

4 indicated by a dotted line is an insulating synthetic resin lining or coating layer, which prevents plating from being deposited on unnecessary areas.

As explained above, in the above embodiment, since two main rods 1 each having a plurality of branch rods 2 driven and fixed are combined, a large number of branch rods can be attached without reducing the strength of the main rod 1. .

Therefore, it is not only durable and long-lasting, but also allows the current to spread uniformly to all parts, making it possible to provide a uniform plating layer even on objects with complex shapes.

Also, since a large number of branch rods 2 can be attached, the main rod 1
Many objects to be plated can be attached without increasing the length, and a uniform plating layer can be provided on each object.

In the above embodiment, a plurality of branch rods 2 are respectively driven into and fixed to the main rod, and the two branch rods 2 are combined with each other at different levels as shown in FIG. 2, but as shown in FIG. As shown in the figure, the branch rods 2 may be combined in parallel, and one main rod 1 may have more branch rods attached than the other.

The main rods 1 may be combined with their upper surfaces and back surfaces or upper surfaces facing each other, or two or more main rods 1 may be combined.

In short, they may be combined in any manner depending on the shape of the object to be plated.

Further, in the above embodiment, as shown in FIG.
The branch rods 2 with a The branch rods 2 may be fixed by welding them by spot welding or the like so that they are on the same plane and driving them into the main rod 1.

In this case, the driving efficiency is further improved.

Furthermore, in the present invention, in order to reduce the electrical resistance of the plating hanger itself, a metal coating layer may be provided on the entire main rod 1 and the portions of the branch rods 2 except for the ends 2a by metal spraying.

Further, the main rod 1 is not limited to being made of copper, and may be made of aluminum since it is not necessary to apply solder.

In this case, since the workability is good, more branch rods can be driven.

As explained above, the present invention consists of two or more main rods in which a plurality of branch rods are driven and fixed, and are aligned and fixed in parallel to each other, so that the number of branch rods fixed to one main rod can be reduced. Even if the number of branches is small, the hanger as a whole can have many branches.

Moreover, since the number of rods fixed to one main rod may be small, the number can be kept within a range sufficient to maintain the strength of the main rod itself.

In addition, since the branch rods are fixed to the main rod by driving, there are fewer manufacturing steps and they are firmly fixed.

In addition, the main rod can be the same as the one used to secure the regular Honmei branch rod, making it excellent for material storage and hanger manufacturing.
