Horizontal chrome plating bath and chrome plating method

Abstract

The invention relates to a horizontal chrome plating bath and a chrome plating method. The horizontal chrome plating bath comprises a bath body. The sidewalls of the two ends of the bath body are provided with circular through holes. Sealing assemblies are mounted on the outer sidewalls of the through holes. A chrome plating anode assembly is mounted on the top of the bath body. The chrome platinganode assembly comprises a plurality of ring-type anode rings and suspension cross beams. Each suspension cross beam comprises a pair of cross beam plates. Each cross beam plate comprises a clampingsection and fastening sections at the two ends of the clamping section. Each anode ring is provided with suspension bars. The ends of the suspension bars are fixedly mounted between the clamping sections of the two cross beam plates of each suspension cross beam. Each sealing assembly comprises an outer sealing flange, an outer seal, an inner sealing flange, an inner seal and a connecting piece. The invention further provides the chrome plating method of the horizontal chrome plating bath. Through the horizontal chrome plating bath and the chrome plating method, the problem that a plating layer is uneven is solved, and a great quantity of precious metal materials can be saved; and the problem existing in plating on long piston rods is solved, multi-length machining on a lot of short pistonrods can be implemented, and the efficiency is improved.

Description

technical field [0001] The invention relates to a horizontal chromium plating bath and a chromium plating method, belonging to the technical field of electroplating devices and electroplating methods. Background technique [0002] Most of the existing electroplating tanks are to immerse the material to be electroplated into the electroplating tank from the top of the electroplating tank. This electroplating method is convenient for small or not long plating parts, but for long rods, because it is more than 20m For long rods, this method of electroplating is inconvenient, and because the rods are too long during electroplating, the rods are suspended at both ends, and the upper and lower plating of the rods is not uniform enough. If the vertical plating is performed, the electroplating tank needs to be made The depth is sufficient, and the horizontal type also needs to have sufficient length. If the electroplating tank is too long, the amount of electroplating solution used i...

[0002] Most of the existing electroplating tanks are to immerse the material to be electroplated into the electroplating tank from the top of the electroplating tank. This electroplating method is convenient for small or not long plating parts, but for long rods, because it is more than 20m For long rods, this method of electroplating is inconvenient, and because the rods are too long during electroplating, the rods are suspended at both ends, and the upper and lower plating of the rods is not uniform enough. If the vertical plating is performed, the electroplating tank needs to be made The depth is sufficient, and the horizontal type also needs to have sufficient length. If the electroplating tank is too long, the amount of electroplating solution used is too much, and the plating layer is uneven during electroplating, and it is easy to discharge at the tip, requiring a lot of auxiliary tooling;

[0003] Traditional electrochrome plating has uneven coating, which is prone to tip discharge, which requires a lot of shielding tooling to avoid, and is limited by the size of the plating tank, too long piston rod cannot be electroplated
