Description

Chromium plating clamping frock

Technical Field

The utility model belongs to the field of metal surface treatment, and particularly relates to a chromium plating clamping tool.

Background

Electroplating refers to a process of plating a layer of metal or alloy on the surface of some metals by an electrochemical method, when electroplating is carried out, the positive and negative poles of a direct current power supply are respectively connected with a metal plate to be plated and a plated piece, after the connection is finished, the metal plate and the plated piece are put together in a plating tank containing a solution of metal ions to be plated, and the metal to be plated is deposited on the negative pole when the direct current power supply is switched on.

Chromium electroplating is a traditional surface modification technology, plays an extremely important role in the electroplating industry, and is classified as one of three major plating species. The effective protection of the metal surface from further wear and corrosion by chromium plating of the metal article surface depends on the excellent wear and corrosion resistance and the strong passivation properties of the chromium itself. For a long time, the chromium plating has high hardness, excellent wear resistance and corrosion resistance, and simple preparation process and low cost, so that the chromium plating technology is widely applied to surface strengthening of various mechanical equipment parts and parts besides being used for decorative coatings, and cannot be replaced by other coatings.

At present, the common clamping mode of chrome plating of parts adopts a copper wire bundling mode, so that the clamping is time-consuming and labor-consuming, the parts are easy to deform and consume a large amount of materials, a chromium layer at the edge of the parts is easy to collapse, deep holes or inner cavity film layers are not uniformly plated, the part film layers are easy to grind due to the fact that the chromium layer is not uniform in the subsequent grinding process, the surface of the parts has no film layers, and the quality is seriously influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a chromium plating clamping frock for the auxiliary cone type part chromium plating, not only the clamping is convenient, repeatedly usable, and the dress hangs the spare part many, material saving, and little with the part clamping point area of contact, it is more even to improve the part deep plating ability messenger internal and external rete.

Technical scheme

The utility model provides a chromium plating clamping frock, includes peg 1, couple 2, cathodic protection circle 3, be equipped with couple 2 on peg 1, couple 2 is back type structure 2 top parallel arrangement cathodic protection circle 3 of couple. The part is clamped by two support points on the hook 2.

The number of the hooks 2 and the cathode protection rings 3 is 3.

When the hook 2 is used for hanging parts, the product is approximately horizontal under the support of the fulcrum, and the warping degree of 2mm is kept.

The cathode protection ring 3 is fixed in the inner cavity of the part.

The hanging rod 1, the hook 2 and the cathode protection ring 3 are made of red copper.

And polishing the contact point position of the hook 2 and the part.

Technical effects

The chromium plating tool can thoroughly solve the problems of large clamping area, time-consuming clamping, material waste, uneven film layer, easy deformation of parts, easy collapse of the film layer and the like of chromium plated parts in the conical inner cavity, is convenient to clamp and reusable, saves material cost and clamping time, and greatly improves the chromium plating qualification rate and production efficiency of the conical parts.

Drawings

FIG. 1 is a schematic structural view of the tool of the present invention;

wherein: a hanging rod-1, a hook-2 and a cathode protection ring-3.

Detailed Description

The following we will make further explanation of the technical solution of the present invention with reference to the attached figure 1: chromium plating clamping frock is including couple 2, cathodic protection circle 3, peg 1. The hanging rod 1 is provided with a hook 2, the hook 2 is of a clip structure, and the top of the hook 2 is provided with a cathode protection ring 3 in parallel. The part is clamped by two support points on the hook 2.

The number of the hooks 2 and the cathode protection rings 3 is 3. The plurality of hooks 2 and the cathode protection ring 3 are arranged on one hanging rod 1 together, so that the surface treatment work of a plurality of parts can be realized.

When the hook 2 is used for hanging parts, a product is approximately horizontal under the support of a fulcrum, and the warping degree of 2mm is kept; and the distance between the two supporting points of the hook 2 can be changed according to the size of the part.

The cathode protection ring 3 is fixed in the inner cavity of the part. And the part is stabilized.

The hook 2 and the contact point position of the part are polished, so that burrs at the contact point position are prevented from hanging on the surface of the part.

The tool is made of red copper, the red copper has good thermal conductivity and electrical conductivity and excellent plasticity, the red copper is processed in hot pressing and cold rolling, the electrical conductivity and the thermal conductivity of the red copper are only second to those of silver, and the red copper has good corrosion resistance. Belongs to industrial pure copper, has rose red color and is purple after an oxide film is formed on the surface. Red copper is copper containing a certain amount of oxygen and is also called oxygen-containing copper.

The specific operation flow is as follows:

firstly, hanging a part on a hook, wherein the hook is in an annular inner shape, and the product is required to be approximately horizontal under the support of a fulcrum, and the warping degree of 2mm is kept; the film is balanced in the horizontal direction under the action of the approximate fulcrum, and the workpiece is convenient to assemble and disassemble without damaging the film. Fixing the cathode protection ring 3 in the inner cavity of the part, and adjusting the positions of the cathode protection ring 3 and the part.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the novel inventive concept of the present invention, and these are all within the scope of the novel invention.
