An electrolytic processing device has an electrolytic tank which comprises separably coupled upper and lower units. The upper and lower units can be coupled to each other to form a single electrolytic tank when electrolytic processing is to be performed. On the other hand, the upper and lower units can be replaced with other units independently. This allows the electrolytic solution in the lower unit to be changed simply by replacing the lower unit with another unit with a different electrolytic solution, without the need for draining and washing the lower unit used previously. |

DETAILED DESCRIPTION Therefore, it is a principle object of the present invention to provide an electrolytic processing device which can solve the aforementioned problem in the prior art.
Another and more specific object of the invention is to provide an electrolytic processing device which allows easy and convenient change of electrolytic solutions.
In order to accomplish the aforementioned and other objects, an electrolytic processing device, according to the present invention, has an electrolytic tank which comprises separably coupled upper and lower units.
The upper and lower units can be coupled to each other to form a single electrolytic tank when electrolytic processing is to be performed.
On the other hand, the upper and lower units can be replaced with other units independently.
This allows the electrolytic solution in the lower unit to be changed simply by replacing the lower unit with another unit with a different electrolytic solution, without the need for draining and washing the lower unit used previously.
In accordance with one aspect of the present invention, a device for electrolytic processing or treatment comprises an electrolytic tank defining a path through which a metal strip passes, and an electrolytic bath containing an electrolytic solution, the tank being made up of first and second separable sections, an electric current supply means disposed in the metal strip path for supplying electric current during electrolytic processing, guide means for retaining the metal strip within the path in the tank and driving the metal strip to move through the electrolytic bath, and means, associated with the first and second sections, for assembling and separating same.
The electrolytic solution can be changed by exchanging at least one of the first and second sections which define the electrolytic bath.
The device further comprises a carrier supporting at least one of the first and second sections of the tank such that the supported section or sections are free to move toward and away from the metal strip path between a first working position and a second exchanging position
