Problems solved by technology

[0002] The brackets of commonly used office chairs mostly use five-claw chair legs. This kind of chair legs need to be electroplated during the production process to ensure the smoothness of the surface of the chair legs. The long electroplating layer is easy to crack and fall off, which affects the appearance of the chair

Embodiment 1

[0032] Embodiment 1, S6 electroplating is electroplating semi-gloss nickel, then electroplating workpiece is placed in the nickel electrolytic cell, carries out electroplating nickel work with electroplating workpiece as cathode, electroplating solution is 25g / L-30g / L nickel sulfate, 40g / L- It is made by mixing 45g / L nickel chloride and 35g / L-40g / L boric acid. The electroplating time is 240 seconds-260 seconds. The plating layer produced in this way is a semi-gloss nickel layer with good flatness and small stress.

Embodiment 2

[0033] Embodiment 2, S6 electroplating is electroplating bright nickel, then the electroplating workpiece is placed in the nickel electrolytic cell, carries out electroplating nickel work with the electroplating workpiece as the cathode, and electroplating solution is 30g / L-35g / L nickel sulfate, 40g / L-45g / L nickel chloride, 40g / L-45g / L boric acid is mixed, and the plating time is 260 seconds to 300 seconds. The plating layer produced in this way is a bright nickel layer with good flatness and good flexibility.

Embodiment 3

[0034] Embodiment 3, S6 electroplating is nickel sealing treatment, then electroplating workpiece is placed in the nickel electrolytic cell, carries out electroplating nickel work with electroplating workpiece as cathode, electroplating solution is 35g / L-40g / L nickel sulfate, 45g / L-50g / L nickel chloride, 45g / L-50g / L boric acid is mixed, and the plating time is 300 seconds to 360 seconds. The coating made in this way is a nickel seal layer, which has good corrosion resistance and high gloss.

Abstract

The invention discloses a stainless steel chair frame electroplating process. Before electroplating, more comprehensive clearing is carried out on an electroplating workpiece, which comprises the steps of clearing away oil contamination on the surface of a metal part and clearing away irregular positions on the surface and edges thereof, so as to enable the surface thereof to be more smooth and cleaner before electroplating, the electroplating quality can be effectively improved, in the electroplating process, multiple kinds of clad layers can be plated by adjusting the formula and proportionof electroplate liquid, the requirements of different chair frames are met, the electroplating process is accurately controlled, passivating treatment is performed after electroplating, the surface ofan electroplated layer is protected, and the service life is long.

Description

technical field [0001] The invention relates to the field of seats, in particular to an electroplating process for a stainless steel chair frame. Background technique [0002] The brackets of commonly used office chairs mostly use five-claw chair legs. This kind of chair legs need to be electroplated during the production process to ensure the smoothness of the surface of the chair legs. The long electroplating layer is easy to crack and fall off, which affects the appearance of the chair. Contents of the invention [0003] The object of the present invention is to provide a stainless steel chair frame electroplating process, which solves the problems raised in the background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a stainless steel chair frame electroplating process, its preparation process is as follows: [0005] S1 thermal degreasing treatment: place the electroplated workpiece in wat...
