Description

ANODE BRIDGE APPARATUS FOR CONTROLLING THE POSITION OF ANODE BLOCK UNIT SEPARATELY}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anode bridge device for mounting an anode melted by electrolysis in a plating cell of an electroplating plant. More specifically, a gap between the conductor roll and the anode is properly adjusted. In order to maintain the state, it is possible to automatically adjust the anode mounting position on a block-by-block basis in the plating plating tank to quickly adjust the precise gap between the conductor roll and the anode to improve the plating quality of the strip significantly. The present invention relates to an anode bridge device capable of unit-by-unit positioning.

In general, the plating facility 200 of the electroplating plant is a conductor roll (204), plating solution injector 208, an anode bridge in the plating bath (200a) as shown in FIG. ANODE BRIDGE) 212, a current device (not shown) for supplying power to the anode 220 is configured.

In the plating cell 200, the plating process is performed by the current of the negative electrode (-) flowing in the conductive roll (CONDUCTOR ROLL) 204 which is rotated while the strip STRIP 206 is wrapped around the anode 220. As the current flows, the anode dissolves in the gap 230 between the anode 220 and the conductor roll 204 by electro-ion chemistry, which leads to a strip 206. ) To be plated.

Thus, the anode 220 is melted by electrolysis as a soluble anode.

On the other hand, when the anode 220 is dissolved and consumed as described above, a new anode 220 is charged in the plating bath 200a, which is performed by a worker using a hoist (HOIST) 240. The new anode 220 is mounted on the anode bridge 212 in 200a, and the lateral movement of the new anode changes the line speed, plating amount, and strip width of the strip in the plating bath 200a. Accordingly, the hydraulic cylinder 252 of the ANODE PUSHER 250 located on one side of the plating bath 200a is connected to the anode 220 by the rod 254 on the opposite side of the plating bath 200a. It is pushed by.

In this process, the spent anode 220 that is pushed on the opposite side of the new anode is pulled out of the plating bath 200a by using the hoist 240a located on the opposite side of the fuser 250.

On the other hand, the gap (GAP) 230 between the conductive control 204 and the anode 220 is a proper gap according to the width of the strip 206, but the width of the strip 206 to 800 ~ 1860mm changes the width of the strip This gap 230 is also required to be changed in various ways because is working while variously transformed.

Accordingly, the anode 220 is replaced and the conductor roll 204, the anode 220, and the gap 230 are illustrated in FIG. 1, by using a small moving jockey 260. BRIDGE) 212 is lifted from the outside of the plating bath 200a, the plurality of bolts (not shown) are loosened and tightened so that the anode 220 becomes a proper gap between the conductor rolls 204. At the end of the adjustment of the anode gap 230.

On the other hand, if the proper anode gap 230 does not fit due to the width change of the extreme strip 206 as described above, the anode 220 interferes with the strip surface 206, or scratches are generated. The foreign material is caught between the anode 220 and the anode 220, and the film is generated. When the conductor roll 204 and the anode gap 230 are too wide, an excessive current flows in any one portion of the plating surface. It is a problem that the color difference occurs or the edge EDGE of the iron plate surface 206 is discolored to black.

Therefore, the conventional anode gap automatic control system as shown in FIG. 2, which is presented to solve this problem, or the tiltable anode gap automation device, can be used between the conductor roll and the anode for a constant strip width change. Gap adjustment is possible, but if the width change is large, there is no function to easily adjust the anode gap individually for each anode block 10 in accordance with the width change of the strip, so when changing the fast strip width up to 800 ~ 1680mm Accurate gap adjustment was impossible. Therefore, in the conventional technique illustrated in FIG. 2, the strip is discolored in black, and scratches due to interference with the anode 220, and a lot of scratches are caused by foreign matter between the anode and the anode.

The present invention is to solve the above conventional problems, the purpose is to adjust the anode mounting position by block unit automatically in the plating plating tank to quickly adjust the precise gap between the conductor roll and the anode The present invention provides an anode bridge device capable of adjusting block-by-block positioning to significantly improve plating quality of strips.

A pair of pillars 63 are erected on the 45, and an inclined block 66 is mounted on the upper end of the pillar 63 so as to be rotatable, and an anode mounting surface (top) on the inclined block 66. 68).

The inclined block 66 is formed to be rotatably mounted on the pillar portion 63 by forming a pin-shaped protrusion 70 on both sides thereof, the rear surface of the inclined block 66 is formed to rotate the inclined block 66 In order to prevent any obstacles from occurring, the upper surface is provided with an anode mounting surface 68 having a cross section corresponding to the rear latching jaw 220a of the anode 220. In addition, the inclined block 66 is connected to the rear surface of the rod 78a of the rotary cylinder 78 located on the upper surface of the moving block 45 to operate the pinned protrusion 70 by the operation of the rotary cylinder 78. It is configured to rotate around the center.

Reference numerals are attached to the upper surface of the anode block 10 through the pin 82 and the long hole 84, the links 86, 90 for connecting the anode blocks 10 integrally with each other are supplied with power Bus bar 92 is a power supply cable.

In the present invention configured as described above, the anode 220 is mounted on the inclined block 66 in the plating bath 200a and sequentially moved, and each anode 220 is moved by the block 10 by the conductor roll 204. ), The gap 230 between the conductor roll 204 and the anode 220 is automatically adjusted.

That is, as shown in FIG. 3, the anode 220 is placed on the anode mounting surface 68 of the inclined block 66 toward the front side of the track frame 12, that is, the conductor roll 204. Positioned opposite to the conductor roll 204, the anode is removed on the rear side of the track frame 12 to move the anode block 10 without the anode mounted. To this end, a hoist 240 is positioned at one side of the galvanizing bath 200a as in the related art, and a new anode 220 is disposed on the anode block 10 which is redirected from the rear surface of the track frame 12 to the front surface. Set on).

In addition, the forward and backward cylinder 50 and the rotation cylinder 78 may be a cylinder operable using pneumatic or electric force.

According to the present invention as described above, the gap between the conductor roll (CONDUCTORROLL) and the anode according to the change in the width of the strip can be adjusted by the anode block 10 according to the change in the width of the strip (STRIP).

Therefore, the standard gap can always be maintained between the conductor roll and the anode, and the gap between the conductor roll and the anode can be quickly adjusted according to the change in the width of the strip. It can prevent the edge burning which turns to black.

It also prevents scratches on the surface by interfering with the anode of the strip, and eliminates problems caused by foreign matter or pinching between the anodes, and plating that can occur when the gap is too wide or narrow. The effect that can prevent the defect of the surface is obtained.
