Electroplating anode device and chromium plating method

Abstract

The invention discloses an electroplating anode device and a chromium plating method. The electroplating anode device comprises multiple anode rods. The multiple anode rods form a cage-shaped structure through supporting of a supporting structure. The cage-shaped structure is used for being arranged on the outer side of a chromium plating area on the outer circle of a workpiece in a sleeving manner. A clearance exists between the anode rods and the outer circle of the workpiece. A cathode gasket is arranged between the cage-shaped structure and the end portion of the outer circle of the workpiece. The anode rods are electrically connected with an anode. The workpiece is electrically connected with a cathode. The anode device is simple in structure, cage-shaped anode and workpiece hanging and electric conduction are integrated, in addition, installation is convenient and fast, practicability is high, and the chromium plating effect is good.

Description

technical field [0001] The invention relates to an electroplating anode device and a chrome plating method, belonging to the field of special process processing methods. Background technique [0002] With the development of industry and the increase in the service life requirements of products, for large structural workpieces, electroplating is no longer the "trunk" part, but the electroplating of key parts such as "branches", which is common in complex workpiece arms, ears, etc. Fork and other key parts, due to the poor dispersibility of the chromium plating solution, the electroplating part needs to be parallel to the anode, and some of the electroplating parts are not parallel to the general anode in the electroplating tank, and are relatively scattered.

Problems solved by technology

[0002] With the development of industry and the increase in the service life requirements of products, for large structural workpieces, electroplating is no longer the "trunk" part, but the electroplating of key parts such as "branches", which is common in complex workpiece arms, ears, etc. Fork and other key parts, due to the poor dispersibility of the chromium plating solution, the electroplating part needs to be parallel to the anode, and some of the electroplating parts are not parallel to the general anode in the electroplating tank, and are relatively scattered. In the electroplating process of such structures, the lines of force are difficult to concentrate, and the current density Uneven dispersion, resulting in uneven deposition thickness of the coating after electroplating, and low electroplating efficiency

[0003] If the workpiece is deliberately rotated at a certain angle so that the electroplating part is parallel to the outer anode, it will be difficult to enter the tank due to the influence of other parts and the size of the electroplating tank, and increase the electroplating operation and safety risks; therefore, it is necessary to design a simple and practical process in the electroplating process device to obtain a uniform and dense qualified coating to achieve its electroplating process
