Description

[Detailed description of the invention] The present invention is an aluminum material hanging and gripping device, in particular, a device for easily suspending aluminum materials at a desired pitch during electrolytic treatment of aluminum materials (hereinafter simply referred to as Al materials). The present invention relates to a hanging and gripping device for Al material, which is capable of providing power and has excellent power supply characteristics and vibration damping characteristics during conveyance of the Al material.

In general, A1 materials such as sash materials, other mold materials, and plate materials undergo necessary surface treatment after being molded before being put on the market.

Surface treatment is usually performed, for example, after molding into a mold material, etc., it goes through various pretreatment processes and is anodized in an electrolytic bath.
Processing is carried out continuously by moving the A1 material in a suspended state to the processing tanks for each process.

However, when processing in this way, the performance of each treatment process is affected by the hanging state of the hanging aluminum material. For example, if the hanging state is unstable during anodizing treatment, the oxide film on the surface may quality has deteriorated, and improvements are desired.

For this reason, various hanging gripping devices have been proposed and implemented in the past, such as devices in which a gripping means made of A1 material is fixed to an electrolytic frame, and devices in which a gripping means is detachably attached. However, there are problems with both devices.
A solution is desired.

That is, a fixed type device is usually constructed by fixing gripping means to an electrolytic frame at a predetermined pitch, and surface treatment is performed by gripping the A1 material at the lower end of the gripping means.

However, in this fixed type device, since the Al material is fixed together with the gripping means to the electrolytic frame, they vibrate together during each process movement, and are difficult to attenuate in a short time. It is easy to put a load on the parts, and there are many problems.

In addition, in order to improve the finish quality during surface treatment, A
It is desirable to suspend the A1 material at a predetermined pitch, taking into account the shape of the A1 material, but since the pitch is fixed and cannot be changed, it is difficult to obtain a high-quality anodic oxide film. , when A1 materials are installed at equal pitches, A
The number of pieces to be installed per piece is reduced, which reduces installation efficiency.

In addition, in the case of a fixed type, unnecessary gripping means are also fixed, so this unnecessary gripping means is likely to get dirty during processing, and furthermore, unnecessary hanging jigs can get in the way when installing Af materials. I don't like it.

For this reason, recently, removable devices have been proposed and implemented in place of fixed devices.

Unlike fixed devices, this device allows you to freely adjust the pitch etc. according to the shape etc. when hanging A1 materials.
Equipment efficiency will improve.

However, this device has a locking part at the upper end of the gripping means that grips the Af material, and this locking part is engaged with the power supply bar to hold the A1 material detachably. At this time, the position of the Af material is easily shifted and the pitch changes, and contact pressure is applied to the power feeding bar only by the weight of the Af material, so power feeding performance is likely to be impaired.

In addition, when the Af material vibrates, the removable device
The contact point of the gripping means is often located on the opposite side to the center of deflection, and as a result, the damping properties are extremely poor. attached, the pitch interval can be freely adjusted, sufficient contact pressure can be applied to the gripping means, Af
We propose a suspension gripping device for Af material that has excellent damping properties even when the material vibrates.

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

Note that FIG. 1 is a front view of a hanging gripping device according to one embodiment of the present invention, and FIG. 2 is a sectional view taken along the AA edge line thereof.

First, in FIGS. 1 and 2, the reference numeral 1 generally indicates a carrier beam, and a plate-shaped support piece 2 is usually provided to protrude downward from the lower side of the carrier beam 1.

The lower part 2a of this support piece 2 is bent, and an inner groove 3 with a V-shaped cross section (hereinafter simply referred to as V-shaped groove 3) is formed inside the bent portion 2a.

) are formed on both sides of the slit 6.

This support piece 2 is made of copper or copper alloy, but AI
Alternatively, it may be made of AI or an alloy thereof. If it is made of AI or an alloy thereof, it is preferable to attach a plate of copper or its alloy to the square groove 3.

Next, in the V-shaped groove 3 according to this configuration, the gripping member 4 that is gripped has the head 4a and the rod-shaped main body portion 4b integrally connected in a T-shape, and grips the Af material 5 at the lower end 4C. The head 4a has a cylindrical shape.

With this configuration, when both ends of the head 4a engage with the V-shaped grooves 3 on both sides, a downward load P is applied to the head 4a by the Af material 5, and the head 4a has a cylindrical shape. Because of this, there is a line contact with the V-shaped groove 3 at two places, and a wedge force Pa perpendicular to each inclined surface of the V-shaped groove 3 is generated at the line contact parts.
acts.

Therefore, the head 4a is pushed by these wedge forces Pa and is wedged into the V-shaped groove 3, thereby being firmly connected.

In addition, in the following, this wedge force Pa causes the head 4a to
4' (Joining by pushing in is abbreviated as wedge joining.

Next, in the support piece 2 having the above configuration, the bent portion 2
Vertical slits 6 are provided at required intervals in a.

This vertical slit 6 is configured so that the gripping member 4 can be aligned, and for this purpose, the width of the vertical slit 6 is the width or diameter of the gripping member 4 (when the gripping member is configured as a bar-shaped member).
equal to or larger than .

Further, as shown in FIG. 1, the vertical slit 6 is configured to reach at least the lowest part of the bent portion 2a, and with this configuration, the gripping member 4 can be aligned with the support piece 2 from the vertical slit 6, The head 4a is then held in engagement within the V-shaped groove 3, while the body portion 4b of the gripping member 4 is held in the longitudinal slit 6 (see FIG. 2).

That is, both ends of the head 4a of the gripping member 4 are inserted into the V-shaped grooves 3 on both sides with the slit 6 in between, and are wedge-coupled.
It is held in place by this wedge connection.

Moreover, since the widths of the main body portion 4b and the vertical slit 6 are matched equally, the main body portion 4b is also held reliably and stably.

Therefore, even if the A1 material 5 vibrates during movement, the head and main body of the gripping member 4 are integrated, and the head and main body are held securely, so it is quickly attenuated.
The A1 material 5 can be held extremely effectively without shifting the pitch interval during movement.

To explain in more detail, the head 4a of the gripping member 4 has a cylindrical shape and is integrally connected to a rod-like main body portion in a T-shape.

Furthermore, both ends of this cylindrical head are wedged into the V-shaped groove 3 by line contact, and since the main body portion 4b is aligned with the slit 6, the head 4a does not move at all. ′, the wedge connection becomes strong.

In other words, as shown in FIG. 1, when a downward load P (mainly the weight of the aluminum material 5) acts on the cylindrical head 4a, two positions of the cylindrical head 4a are moved against the V-shaped groove 3. At the line contact portion, a component force Pa of two loads P presses the V-shaped groove 3, resulting in a wedge connection.

However, even in this state, the head 4a due to vibration of the AI member
When the head 4a moves in its axial direction, the head 4a does not fit into the V-shaped groove 3, and the two component forces Pa are small, making it impossible to achieve a wedge connection.

In this regard, in the present invention, since the width of the rod-shaped main body portion 4b matches the width of the slit 6, the movement of the head 4a in the axial direction is completely prevented, and the two component forces Pa are maximized, ensuring that Combine wedges.

Therefore, by appropriately setting the included angle of the V-shaped groove 3, an appropriate contact pressure can be obtained, the gripping member 4 and the A1 material 5 can be securely held, and they can be prevented from swinging during movement during each process of surface treatment. too,
The vibrations also quickly decay.

In addition, the circular head 4a is heated under extremely high pressure as described above.
As the AI-shaped material contacts the V-shaped groove 3 and is constantly vibrated appropriately during transportation by crane, intervening components such as oxide film at the contact area are removed, and the contact area can maintain a close contact state, which facilitates power supply during electrolysis. Sexuality also improves.

As mentioned above, even if the upper end of the gripping member 4 does not necessarily have a cylindrical shape, the wedge effect described above can be achieved as long as the upper end of the gripping member 4 is in line contact with the V-shaped groove 3. Instead of having a cylindrical shape, for example, the gripping member 4 can be configured as a semi-cylindrical shape with a flat upper end and an arcuate shape only at the contact portion.

Further, although it is usually sufficient for the gripping member 4 to be made of a conductive material, since the V-shaped groove 3 is made of copper or a copper alloy, the head 4a at the upper end is made of copper or a copper alloy. Preferably, it is configured.

Further, the lower end 4C of the gripping member 4 grips the upper end of the aluminum material 5, but it is sufficient if the gripping portion 4C is configured as in the conventional example.

In addition, since the gripping frame 4 whose upper end is held as described above is inserted from the vertical slit 6, and the rod-shaped main body portion 4b is aligned with the vertical slit 6, the gripping member 4 can be held more securely. Even if the A1 material 5 swings during movement, its amplitude is small and quickly attenuates.

In addition, if the vertical slits 6 are constructed with as small a pitch as possible, by selecting an appropriate pitch interval, the interval between the A1 members can be adjusted as desired according to the shape, size, etc. of the A1 material. can.

As explained in detail above, the present invention locks the gripping member that grips the aluminum material in line contact with the V-shaped groove on the lower side of the carrier beam, etc., and holds the gripping member by holding it with a vertical slit. Therefore, the gripping member is removable, the interval between the A1 intervals can be adjusted freely, and there is no inclusion such as an oxide film on the contact portion of the gripping member, improving power supply characteristics.
