Title: DEVICE AND METHOD FOR THE PARTIAL ELECTROCHEMICAL TREATMENT OF BAR-SHAPED ELEMENTS
Abstract:
The invention relates to a device and method for the partial electrochemical treatment of bars (10) in dipping bath installations. Said device and method aims to solve the problem that the bars (10) which are held in various positions by holding pliers during treatment should only be treated electrochemically in precisely defined central areas. To this end, the bars (10) are inserted into membrane supports (23), used to fix shielding diaphragms (8) for the bars (10) and into electrodes (30) and are electrochemically treated once they have reached a position for electroplating. In order for the bars (10) to reach said electroplating position, they are first inserted into the membrane supports (23) until they reach a defined adjusting position, whereby the membrane supports (23) are displaced into a locking position. The membrane supports (23) are subsequently fixed in said locking position and the bars (10) are then moved into the electroplating position.
