ELECTROLYTIC PICKLING DEVICE

摘要

PURPOSE: An electrolytic pickling device is provided which improves efficiency of work in removing an oxide coating film by having a simple structure so that the oxide coating film remained on the surface of a sample is treated promptly, accurately and easily. CONSTITUTION: The electrolytic pickling device is characterized in that a sample mount(4) to which a sample(3) is fixed is installed at the upper part of an insulation plate(2); cylindrical or disk shaped fixing members(5,6) are consecutively installed at the lower part of the sample mount(4) so that they are coupled and fixed by a coupling nut(8) with a control handle(7) interposed between the fixing members(5,6) and the coupling nut(8); an insulation guide block(10) in which an O-ring(9) is installed and a tapered tube(11) which is inserted at the center of the insulation guide block(10) are formed at the upper side of the insulation plate(2) to which the sample(3) is fixed through the sample mount(4); an aluminum block and an acryl tube(14) are consecutively equipped at the upper side of the tapered tube(11), wherein a nozzle(13) controlling flow of a pickling solution so that the sample(3) is easily pickled is installed at the acryl tube(14); an electrode(19) supported to the lower side of a block(18) is inserted into the acryl tube(14); an aluminum support plate(20) is positioned at the upper side of the block(18) so that the aluminum support plate(20) is integrally coupled to the insulation plate(2) by a coupling bolt and a wing nut(22); and bushes(15) are installed at each corner parts of the upper side of the insulation plate(2) so that an aluminum block is installed on the bushes(15), and the sample(3) is positioned in the aluminum block.
