Description

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

This type of plating banger hooks or clamps the object to be plated on the end of the branch rod and conducts current from the main rod through the branch rod to the object to be plated, so the branch rod is firmly fixed to the main rod without wobbling. It is required that the electrical contact resistance be as low as possible.

For this reason, the present applicant recently proposed a new technique characterized by forming a horseshoe-shaped bent part in the branch rod, and driving and fixing the part of the branch including this bent part to the main rod, and solving the above-mentioned problems. (Japanese Patent Application No. 54-140239).

By the way, in this technology proposed earlier by the applicant,
Because the branch rod itself must be bent to form the bent part, the processing work is relatively separate, and each branch rod is a separate unit until the main rod is driven and fixed. When driving into the main rod, the posture of each branch rod must be fixed so that it does not move or shift, which makes the driving work complicated.

Therefore, the applicant has developed a technique for welding multiple branch rods to one member, and in which multiple units, each of which is considered one unit, are arranged along the longitudinal direction of the main rod, and the members of each unit and the branches in the vicinity thereof are We proposed a banger for plating, in which the rod part is fixed by driving the main rod ζ, and tried to eliminate the above-mentioned drawbacks (Japanese Patent Application No. 54-1
No. 35455).

However, by simply welding multiple branch rods to one member,
When the center lines of the branch rod and the member do not match, a large force is applied to the intersection between the two, resulting in broken or bent branches or members.

In view of these circumstances, it is an object of the present invention to provide a plating banger that eliminates the above-mentioned drawbacks.

In the present invention, a plurality of branch rods are welded to one member so as to be on the same plane as the other member (this is one unit), and a plurality of units with this as one unit are arranged along the longitudinal direction of the main rod. It is characterized by the fact that each unit member and its neighboring branch rods are driven into place by driving the main rod into place.

Embodiments of the present invention will be described below based on the drawings.

Figure 1 shows an example of this, in which 1 is a main rod with a hook shape 1a formed on the upper part, 2... are stainless steel branch rods of appropriate length, and 3... are S-shaped. It is a bent member made of stainless steel, for example.

Note that this part (third...) does not need to be made of stainless steel.
As described below, any material can be used as long as it can be welded by spot welding or the like to the Q-branch rod 2....

Therefore, it is also possible to use a metal that is easy to bend into an S-shape or the like.

In order to manufacture a plating nozzle from each of these component parts, first, a plurality of branch rods 2, for example, two branches 2... are crossed with one member 3, and the center line of the branch rods 2... One unit is a part welded by spot welding etc. so that the center line of the member 3 is on the same plane -L (see Fig. 2 and Fig. 3 B),
Make multiple units of it.

Next, these multiple units are arranged along the longitudinal direction of the main rod 1, and in this state, the member 3 of each unit and the branch rod portion are pressed and driven into the main rod 1 and fixed (see Fig. 3B). ).

After driving, the entire branch rod 2 except both ends is coated with an insulating resin film 4 as shown by the chain line in FIG. 3A.

In addition, as the member 3 for welding the branch rods 2..., the above-mentioned S
In addition to the letter shape, a C-shaped member as shown in FIG. 4A or an X-shaped member as shown in FIG. 4B can also be used.

Further, the number of branch rods 2 to be welded to each member 3 may be four as shown in FIG. 5, or may be more than four.

As described above, the plating banger according to the present invention is made by welding a plurality of branch rods 2... to one member 3 so that they are on the same plane as the member 3, and a plurality of branch rods 2 with this as one unit. Since the units are arranged along the longitudinal direction ζ of the main rod 1, and the member 3 of each unit and the branch rod portion in the vicinity thereof are driven into the main rod 1 and fixed, the following effects are obtained.

First, multiple branch rods are welded to one member, and this is driven into the main rod to secure it, so it is firmly fixed, and since the branch rods and the main rod are in close contact, the electrical resistance is low. , and has good conductivity.

Moreover, since multiple branch rods are welded to one member and then driven into the main rod and fixed, even if a conductive failure occurs between the main rod and some of the branch rods, Since electricity is conducted through other branch rods, there is no risk of the object being plated becoming damaged.

In addition, since multiple branch rods are welded to one member and are driven into place, each branch rod does not move individually during driving, and there is no need to fix the posture of each branch rod. Therefore, the driving work is easy.

At the same time, the amount of driving work can be extremely reduced since it only needs to be done in units of units.

Furthermore, since the component and the branch rod are welded so that they are on the same plane and are driven into the main rod and fixed, there is no large force applied to the intersection between the component and the branch rod, and the component or branch rod is fixed. With almost no breakage or bending of the rod, highly accurate plating bangers can now be obtained.
