Description
Technical field
The invention belongs to electrochemical surface treatment fields, and in particular to a kind of auxiliary cathode for barrel gutter chromium plating
Device, especially a kind of 76mm barrel gutter chromium plating metal and nonmetallic compound auxiliary cathode device.
Background technique
In machining, wear-resisting, corrosion resistant, heat-resisting and photoelectromagnetic etc. can be increased using process for treating surface for machine components
Various miscellaneous functions.Electrodeposited chromium is a kind of electrochemical surface treatment technology, and the wear-resisting of its surface can be improved after machine components chromium plating
With the functions such as corrosion resistant.The characteristics of chrome-plated process is that current density is big, and current efficiency is low, and the device is complicated, and structure is complicated for process unit,
Plated piece surface layers of chrome is in uneven thickness, and seamed edge crystallization is coarse.
Summary of the invention
The object of the present invention is to provide a kind of auxiliary cathode devices for barrel gutter chromium plating, solve barrel gutter
Chrome layer problem in uneven thickness and seamed edge crystallize coarse problem.
The technical solution of the present invention is as follows: a kind of auxiliary cathode device for barrel gutter chromium plating, it is characterised in that: packet
Include sheet metal 1, cage axis tile 2 and iron wire hoop 3；Cage axis tile 2 is nonmetallic materials, and outer dimension imitates barrel gutter shape,
The cage item of cage axis tile 2 is to be vertically arranged, and cage length and width dimensions are suitable with gutter convex surface, and spacing is suitable with gutter concave surface,
Each cage inner surface of cage axis tile 2 is respectively fixed with a sheet metal 1；2 obvolvent of cage axis tile in barrel gutter outer surface,
And it is fixed by iron wire hoop 3；Sheet metal 1 is sufficiently bonded with barrel gutter convex surface, and cage item will block at gutter convex surface,
Sheet metal width is greater than cage width, exposes a part, for absorbing the stray electrical current of gutter seamed edge.
The utility model has the advantages that the configuration of the present invention is simple, it is ensured that chrome layer thickness uniformity makes seamed edge crystallize coarse problem and disappears
It removes, working efficiency is greatly improved, and ensure that barrel chromium plating quality in loading, unloading and easy to maintain.

Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, below with reference to embodiment, to specific implementation of the invention
Mode is described in further detail.
The present invention provides a kind of auxiliary cathode device for barrel gutter chromium plating, including sheet metal 1, cage axis tile 2
With iron wire hoop 3；Cage axis tile 2 is made of together two 2 obvolvents of semicircle cage axis tile, and is fixed in by iron wire hoop 3
Barrel gutter outer surface；Each cage inner surface of cage axis tile 2 respectively posts a sheet metal 1；
Sheet metal 1 is placed at barrel gutter convex surface, and thickness selection is suitable for length and width dimensions and gutter convex surface
Match, to absorb " stray electrical current " of barrel gutter seamed edge；
Cage axis tile 2 is manufactured using the nonmetallic materials of resistance to chromic acid corrosion, and outer dimension imitates barrel gutter shape, cage item
To be vertically arranged, cage length and width dimensions are suitable with gutter convex surface, and spacing is suitable with gutter concave surface, two and half large carrying food-baskets when installation
For 2 obvolvent of formula axis tile in barrel gutter outer surface, cage item makees power line all to blocking at corresponding gutter convex surface
Used in gutter concave surface, accelerate concave surface layers of chrome deposition velocity, cage length and width dimensions should be with 1 length and width dimensions of sheet metal
Match, sheet metal 1 is made to be only involved in the absorption of " stray electrical current " of gutter seamed edge；The width of sheet metal is slightly larger than the width of cage item,
Make it after mounting, sheet metal exposes a part, only absorbs the stray electrical current of barrel gutter seamed edge.The width of sheet metal can be with
Beyond land width a part, preferably 0.05-0.1mm.
Iron wire hoop 3 plays the role of being fixedly clamped and guaranteeing that sheet metal fitting is conductive adequately.
The present invention is used cooperatively simultaneously with chromium plating conductive fixture, can be used for the part chromium plating of surface relief structures.In plating body
When pipe gutter, two 2 obvolvents of semicircle cage axis tile make sheet metal 1 to convex surface both sides " stray electrical in barrel gutter outer surface
Stream " can uniform pickup be advisable, be then fixedly clamped with iron wire hoop 3, and check sheet metal 1 be bonded with barrel gutter convex surface whether
Sufficiently.Auxiliary cathode is installed, by conductive fixture by after Workpiece clamping, enters Cr-plating Bath with part and carries out chromium plating
Processing.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
