Description

[Detailed description of the invention] This invention relates to a hanging hanger for electrodeposition coating.

Conventionally, a hanger branch fixed to a hanger body connected to one electrode is formed of a rod-shaped member. For this reason, vibrations may occur when the rod-shaped hanger branch is inserted into a hole drilled in the workpiece and the workpiece is suspended, and the workpiece is transported together with the hanging hanger by a conveyor. According to
There was a problem that the object to be coated vibrated against the hanger branch, and sometimes the object to be coated would slip out of the hanger branch and fall. Further, when the object to be coated is immersed in an electrocoating paint bath and subjected to electrodeposition coating while suspended from the hanger branch, the object to be coated sometimes floats up to the hanger branch, causing failure in electrical conduction.

In view of the above reasons, the purpose of this invention is to provide a hanger for electrodeposition coating that can prevent the object to be coated from swinging or lifting from the hanger branch.

Therefore, in this invention, the hanger branch is formed from a tapered plate member whose plate width gradually increases from the distal end to the proximal end, and the hanger branch is covered with A locking edge is formed that engages with the through hole of the coated article, and the coated article is suspended at a predetermined position on the hanger branch.

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, a hanging hanger 3 suspended from a hanging fitting of a hanger conveyor 1 is mainly composed of a hanger body 4 and a hanger branch 5.

In order to perform electrodeposition coating, the hanger main body 4 connected to one electrode is formed into an inverted U shape, and a hook 6 that engages with the hanging fitting 2 of the conveyor 1 is formed in the center of the upper side. There is.

Hanger branches 5 are electrically connected and fixed to both the left and right support parts 4a of the hanger main body 4, and the hanger branches 5 are formed from a plate-shaped member such as a steel plate or a stainless steel plate, and have a base end thereof. A mounting piece 5a for the hanger main body 4 is formed. Furthermore, in its planar shape, the hanger branch 5 is formed so that the plate width at the tip is as narrow as possible so that it can be inserted and removed freely into the through-hole Wa of the object W, and from that part to the base. The width of the plate gradually increases toward the end, forming a tapered (triangular) shape.
Moreover, along the tapered portions of both side edges of the hanger branch 5, there are provided upwardly protruding locking edges 6 that are serrated and engage with the through holes Wa of the object W to be coated. In this embodiment, when the hanger branch 5 is formed by punching in a press, the "burrs" generated along the tapered portions of both side edges of the hanger branch 5 form the locking edge 6 as they are. It is. Further, the hanger branch 5 has a third
As shown by the chain line in the figure, it is appropriately bent in the vertical direction, and its tip is inclined upward.

In the hanging hanger 3 configured as described above, the hanger branch 5
When the workpiece W is suspended by inserting the hanger branch 5, both locking edges 6 of the hanger branch 5 engage with the through holes Wa of the workpiece W, and the workpiece W is engaged in a predetermined position of the hanger branch 5. This prevents the object W from swinging or lifting.

In addition, if the locking edge 6 of the hanger branch 5 is coated with paint for electrodeposition, when the hanger branch 5 is inserted into the through-hole Wa of the object W to be coated, When transferring the coating material W toward the electrodeposition paint tank, the locking edge 6 of the hanger branch 5 and the coating material W
The paint adhered to the locking edge 6 is peeled off due to the frictional force generated between the through-hole Wa and the inner circumferential surface of the through-hole Wa.
It is also possible to prevent malfunctions in energization.

In addition, in the above embodiment, the hanger branch 5
The locking edge 6 is a serrated "burr" that occurs along the tapered portions of both side edges of the hanger branch 5 when the hanger branch 5 is formed by punching, but the locking edge 6 is not limited to this. The locking edge 6 may be formed into a saw-tooth shape by cutting, pressing, or the like.
Furthermore, among the tapered portions of both side edges of the hanger branch 5,
It is also effective to form the locking edge 6 only on one side edge taper portion.

In other words, in this invention, the width of the hanger branch formed from a plate-like member is gradually expanded from the tip to the base, so that the through-holes of various types of objects may differ in size. However, these objects to be coated can be effectively suspended by the same hanger branch. Furthermore, the locking edge of the hanger branch can lock and hold the object to be coated to prevent the object from swinging relative to the hanger branch, and when the object is immersed in the electrodeposition paint bath. Since lifting of the object to be coated which occurs can be prevented, the object to be coated can be well coated by electrodeposition.
