Description

[Detailed Description of the Invention] The present invention relates to a holder used when forming an anodic oxide film (alumite processing) on aluminum parts such as pots.

To apply alumite processing to aluminum parts, degreasing, water washing, neutralization, water washing, electrolysis (oxidation film treatment), water washing, drying,
This is done by linking each process of steam can processing, but in order to mass-produce it, a holder with the aluminum parts to be processed is suspended on an energized frame that is continuously moved by a conveyor. A method is adopted in which each of the above-mentioned processes is performed.

The efficiency of this alumite processing is greatly affected by the efficiency with which parts are attached to and removed from the holder.

Conventionally, for alumite processing of a part such as a pot that has a cylindrical part, a cylindrical part 2 such as a pot is attached to a ring 1 of aluminum wire that also serves as a conductor, as shown in Fig. 5a, l). Either insert the parts into each other and suspend them on the current-carrying frame using the hanger 3 (see Figure 5a), or sandwich the component 2 with the aluminum strands 1' tied to the current-carrying frame, and tighten the top and bottom with the fasteners 3'. A suspension method (see Figure 5) was used.

These methods have the disadvantage that when the parts are small or there are many parts, it takes time to attach and detach the suspension members such as the ring 1 and the wire 1' and the related hangers 3 and fasteners 3', which hinders productivity. In addition, the suspension members were wasted, which was very uneconomical.

In the present invention, the cylindrical part of the workpiece is inserted into an equilateral or nearly equilateral quadrilateral frame that can be freely deformed into a rhombus shape, and rubber or the like is inserted between the outer frames at diagonal positions of the quadrilateral frame. The quadrilateral frame is transformed into a diamond-shaped frame by passing elastic cords around it, and the deformation of this frame allows the parts to be strongly clamped within the frame and energized, and the energizing hook provided on the frame allows the frame to be placed above the processing tank. The present invention relates to an easily attachable and detachable holder for anodic oxide film production, which is suspended from a current-carrying frame attached to a moving conveyor.

The contents of the present invention will be explained in detail below according to embodiments shown in the drawings.

FIG. 1 is a front view of a holder for forming an anodic oxide film according to the present invention, and FIG. 2 is a perspective view of section A in FIG. 1.

As shown in the figure, a vertical rod 5 made of a conductive material such as aluminum or aluminum alloy strip having a power supply hook 4 (see FIG. 2a) at the tip is placed in the center, and vertical rods 6 and 6' are arranged on both sides of the vertical rod 5. , across the vertical rods 6 and 6' on both sides, the horizontal rods 7 (see Figure 3 a, l)) are arranged at equal intervals of 5 in the example.
The books are arranged in parallel and both ends of each horizontal rod 7 are pivotally connected to the vertical rods 6, 6'.

Further, the center portions of the uppermost row and the lowermost row of the horizontal rods 7 arranged in parallel are pivotally connected to the vertical rods 5.

The horizontal rod 7 is connected to the vertical rod 5 as shown in Figures 2a and 3.
, 6, and 6' are stepped from the other surface openings by the thickness of the vertical rod, but this is done so that the clamping surfaces of each frame that clamps the parts are on the same plane. be.

In this way, the vertical rods 5, 6, 6' and the plurality of horizontal rods 7 form a frame body, that is, a component holder, thereby forming a plurality of (eight in the illustrated example) four-sided frames 8.

The inner dimension of this frame 8 is slightly larger than the outer diameter of the workpiece, and the horizontal dimension l and the vertical dimension 1' are made equal.

In other words, a quadrilateral frame with equal sides is constructed. The part 2 having the cylindrical part that requires alumite processing is inserted into the quadrilateral frame 8 of the holder configured as described above (see Figure 4).Next, as shown in Figure 4a, the vertical rod is inserted. An elastic string 11 made of rubber or the like with hooks on both sides is strung diagonally on the outside of 6 and 6'.
This biasing force deforms the frame 8 into a diamond shape, and the component 2 is held between its inner surfaces so as to be electrically conductive.

The holder holding the part 2 in this manner is suspended by the current-carrying hook 4 from the current-carrying frame of a moving conveyor (not shown) mounted above the alumite treatment tank array (not shown), and is placed inside the processing process. The product is transported to alumite processing.

When the alumite processing is completed, remove the holder from the current carrying frame,
When placed on a carry-out conveyor (not shown), the elastic string 11 is removed, the frame 8 is returned to a square shape, and the holder is lifted, the workpiece leaves the holder and remains on the carry-out conveyor and is carried out.

The holder is made of aluminum or aluminum alloy so as not to adversely affect the electrical conductivity of the workpiece and the alumite processing.

The holder that has undergone the first step of alumite processing has an insulating oxide film formed on it like the workpiece, so it is defilmed with caustic soda and prepared for the next step of alumite processing.

As described above, in the holder of the present invention, when a workpiece is mounted in the frame 8 or removed, the elastic string 11 is hung on the holder to make the frame 8 diamond-shaped, or the frame 8 is formed by removing the elastic string 11. Since each part can be completed with one operation of returning to a square shape, it is extremely easy to attach and detach parts, which reduces the time required to attach and detach parts and improves processing efficiency. It also has the effect of saving labor by promoting productivity improvements, such as the ability to process a large number of parts with just one person.

Next, in the upper row, all of the vertical frames 5, 6, 6' and horizontal rods 7 that make up the holder are electrical conductors, but since the component 2 is held in the frame 8 with four points of contact, they are electrical conductors. Even if only the vertical rod 5 is used, the component 2 can be sufficiently energized.

Therefore, the vertical bars 6, 6 other than the vertical bars 5 having the current-carrying hooks 4
' and the horizontal rod 7 may be made of a material that cannot be immersed in the alumite treatment solution, such as synthetic resin.

In this case, if the interval between the vertical rods is made slightly narrower than that between the horizontal rods, the frame 8 is deformed into a rhombus shape, and the vertical rods 5, 6, 6' forcefully press the component 2, thereby making it possible to conduct electricity reliably.

In this way, the oxide film removal treatment that is performed every time the alumite processing process is completed can be limited to only the vertical rods 5, reducing the complexity of post-processing and reducing the wear and tear on the holding members. can.

In addition, the vertical rod 5 and the horizontal rod 7 are connected by providing a lock-shaped hole 9 in the vertical rod 5 and a locking pin 10 in the horizontal rod 7, as shown in Figure 2. If the vertical rod 5 and the horizontal rod 7 are connected by engaging and fitting the lock-shaped hole 9 into this latch pin 10, then by engaging the hole 9 with the pin 10 and pulling up the vertical rod 5, The horizontal rods 7, and therefore the holders constituting the frame, are connected together and can be pulled up, making it extremely easy to attach and detach the vertical rods 5.

As described above, according to the present invention, attachment and detachment of parts, post-processing of connectors, etc. are extremely easy, and there is a practical effect that greatly contributes to improvement of workability, productivity, and labor saving.
