Description

Shaft part chromium plating tool

Technical Field

The utility model relates to an electroplate frock technical field, especially relate to an axle type part chromium plating frock.

Background

Chromium coatings have excellent properties and are widely used as an outer skin and functional coating for protecting a decorative coating system, and have always been an important place in the electroplating industry. The chromium coating has high hardness, and a coating with a hardness value of 400-1200 HV can be obtained according to different components and operation conditions of the chromium coating solution. The chromium coating has a low coefficient of friction, in particular the dry coefficient of friction, which is the lowest of all metals, and therefore has a very good wear resistance.

Shaft parts are mechanical parts which support rotating parts and rotate together with the rotating parts to transfer motion, torque or bending moment, and have higher requirements on wear resistance and surface hardness, so that surface chromium plating is one of the most common surface treatment modes of the shaft parts.

The technology of electroplating chromium is relatively mature in the prior art, but for the chromium plating of shaft parts, the following problems still exist:

1. at present, most of shaft part chromium plating tools are special tools, each tool can only clamp one part, and strict requirements are imposed on the size of the part for ensuring the conductivity;

2. the existing chromium plating tool for the shaft parts needs to clamp the excircle of the part during clamping, the excircle of the shaft part is generally a working surface, and the clamping position cannot deposit a plating layer due to the isolation of an electroplating solution and the existence of clamp tooth dispersed current, so that the completeness of the plating layer of the excircle of the part is influenced;

3. because the volume of a common chromium plating tank is small, the electroplating time is long, and meanwhile, intervals must be carried out among every set of tools, the number of parts for carrying out chromium plating each time is small, and a large amount of manpower and material resources are wasted.

4. Because the chromium plating bath solution has certain corrosivity, the chromium plating tool, especially the clamp of the clamping part, can be corroded by the bath solution after being used for a period of time to influence the usability, the clamp of the chromium plating tool at present adopts a threaded connection or welding mode mostly, the whole tool needs to be replaced after the threaded hole is corroded by the solution, and the welding mode is not beneficial to replacing the tool clamp.
