Description

[Detailed Description of the Invention] The present invention relates to a jig used for vertically suspending a long material such as an Al extruded material.

In order to form a surface oxide film on an Al extruded material, one end of the elongated material (hereinafter abbreviated as "elongated material") is usually gripped by a vertical hanging jig 3, as shown in Fig. 1. The operation of holding it, hanging it on the power supply bar 21 and hanging it vertically, transporting it in the vertically hanging state, immersing it in a washing tank or an electrolytic bath (not shown), or pulling it up is repeated.

The power supply bar 21 may be a straight bar as shown in FIG. 1A, or may be a hook-shaped member as shown in FIG. 1B. In the case of a hook-shaped body, the hook-shaped body is implanted in a straight line in the bar base 22, so the lines connecting the points on which the jig 3 is hooked are all straight lines, This will be called the hook base line X.

As shown in the figure, the hanging jig 3 has a rod-shaped hanging shaft 3a.
However, it is integrally equipped with a hook-shaped hook part 3b on the upper side and a clamping part 3c for gripping and holding the long material F on the lower side, and the long material F is attached to the clamping tool 3 one by one at one end.
c and is hooked onto the power supply bar 21 by the hook portion 3b. Of course, this hooking interval, that is, the distance between the elongated materials, must be determined based on the specific spacing required as the electrolytic conditions and the unique shape of the elongated materials.

FIG. 2 shows a state in which the power supply bar with the long material suspended in this manner is immersed in a processing tank 1 such as an electrolytic tank with both ends of the power supply bar base 21 suspended from the tank wall. In the partial top view of FIG.

By the way, in this way, a large number of long materials are hooked to the power supply bar, and as mentioned above, the power supply bar is transported as it is and is processed in each tank. The vibrations not only within but also during the transfer are small in the A direction and large in the B direction.
In any case, if adjacent elongated materials come into contact with each other, electrolysis failure will occur, so the hanging distances l and m cannot be made too narrow.

On the other hand, in order to increase processing capacity, in other words, productivity, it is necessary to minimize l and m as much as possible, increase the number of hangings, and improve the hanging speed to the power supply bar. If the wires are manually suspended one by one, l and m may be unnecessarily set too large or too small, which may cause the electrolysis failure described above. Therefore, it is important to use a hanging jig that has a clamping part that satisfies at least one of the distances l and m that are predetermined based on past operating results, and if possible, to satisfy both. Instead, it is desirable to use a hanging jig that can suspend multiple pieces at the same time.

The present invention was developed from this point of view, and as shown in FIG. The gripping portion 33 includes a pair of gripping portions 33A and 33B.
One vertical plane P including the center line O of the suspension shaft and the hooking base line X to the power supply bar, and the center line O
It is provided at a symmetrical position on the same horizontal plane with respect to the center line O in the odd quadrant or even quadrant among the four quadrants formed by the other vertical plane Q orthogonal to the one vertical plane P including It is characterized by this. In other words, this jig is the same as the conventional one up to the hook-shaped hook part 31 and the hanging shaft 32, but the gripping parts are 33a, 33b from the lower part of the hanging shaft.
and a clamping portion 33 at each end thereof.
A, 33B are provided.

Although FIG. 3 shows a case in which the clamping tools are provided in odd-numbered quadrants, it is obvious that the same holds true even in even-numbered quadrants. In any case, in order to provide a pair of clamping parts in symmetrical positions, as shown in Fig. 4, which is a rewrite of Fig. 3, it is necessary to )
The position is m/2 from

The suspended state of the jig of the present invention is as shown in FIG. The worker holds the pair of clamping parts 3
3A and 33B, the jig of the present invention holding a long material is hooked onto the power supply bar 21,
The only thing that must be taken into consideration in this case is that the distance between the first jig 30 and the next jig 30' be m. Then, the long materials are automatically suspended at predetermined intervals l and m.

As described above, according to the jig of the present invention, not only the hanging efficiency is significantly improved, but also the predetermined intervals l and m between the long materials are regulated as a jig.
Accidents caused by poor electrolysis caused by inexperience or inexperience with suspension operations are significantly improved.
