[ detailed description ] embodiments

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

Referring to fig. 1-3, a W-shaped auxiliary anode plating hanger includes a hanger 1, a connecting frame 2, and at least two sets of auxiliary anodes 3, wherein the hanger 1 is a metal member, the upper two parts of the rack are provided with hooks 4, the rack 1 is conveniently hung on a bracket for hanging in the electroplating process or after the electroplating, the rack 1 is of a structure similar to a ladder, since the hanger 1 is an iron member, a rust-proof layer is generally coated on the surface for rust-proof enhancement, the utility model discloses in increased supplementary positive pole 3, to among the current electroplating technique, because some dispersion ability and the relatively poor plating bath of deep-plating ability, in addition some plate the piece and have comparatively hidden structure that does not open (for example deep concavity and intraduct etc.) cause easily that the power line can not evenly reach on the piece of plating, electric power can evenly pass cloth on the plated item when electroplating, has added supplementary positive pole.

As shown in fig. 1, the connecting frame 2 is fixed and electrically connected to the upper portion of the hanging frame 1, the connecting frame 2 is electrically connected to the hanging frame 1 through a wire, and the auxiliary anode 3 is detachably connected to the hanging frame 1 in parallel. The link 2 is the structure of T type, and its one side can freely be assembled and dismantle through the screw connection with stores pylon 1, the electric wire of another side end connection circular telegram, but be electrically conductive between link 2 and the stores pylon 1, circular telegram back, the electric current passes through link 2 and conducts to stores pylon 1 on any place, according to stores pylon 1's overall dimension and the product quantity that will electroplate and the supplementary positive pole 3 of size selection corresponding quantity, the utility model discloses in choose for use two supplementary positive poles 3, supplementary positive pole 3 can freely assemble and dismantle with link 2, select according to whether need supplementary positive pole 3, when the effect is electroplated in the realization that does not need supplementary positive pole 3 also can be fine, do not select it can the energy saving to accelerate the progress of work simultaneously, make things convenient for the operation process.

More importantly, as shown in fig. 3, the auxiliary anode 3 is arranged in a W-shaped structure. The conventional auxiliary anode is generally in a planar strip shape, the current distribution on an electroplated part is easily uneven due to the planar auxiliary anode, so that the compactness of plating solution ions combined on an electroplated product is deviated, the uniformity of the thickness of a film layer cannot be formed, the auxiliary anode 3 is improved into a W shape, and the uniformity of the formation of the plating layer is ensured in the electroplating process.

The auxiliary anode 3 is made of iron material, the auxiliary anode 3 mainly makes the electric lines of force of each part of the plated part equal, the auxiliary anode 3 generally adopts insoluble anode, such as lead plate or iron plate; although soluble, it is noted that the dissolution of sludge and lead of the anode can be affected, and the auxiliary anode 3 can be protected by iron wire or copper wire with thickness and distance to prevent the product from concentrating the electric field lines and causing the coating to be too thick or even scorching.

In addition, as shown in fig. 1, the hanging rack 1 includes a plurality of hanging rods 101 arranged in parallel, the hanging rods 101 include at least one hanging position 102, and the hanging position 102 is provided with a plurality of hanging strips 103 for hanging products. During electroplating operation, will hang the product of treating that a large amount is more on the stores pylon 1, consequently, set up a plurality of peg 101 and hang position 102, the utility model discloses in, be provided with three string position 102 on every peg 101, hang position 102 and be a convex joint body, be favorable to the electric current evenly to conduct on the hanging strip 103, every hanging strip 103 on the position 102 has six, and it respectively has threely to hang position 102 both sides, during electroplating, hangs the product on the hanging strip 103, must notice, to the size of a dimension of product, the interval of rational arrangement rack plating avoids the product to appear the contact and influence electroplating's effect.

The utility model discloses improve the supplementary hanger that is W type structure with current supplementary hanger, the effectual defect that improves the cladding material thickness inhomogeneity that brings of power line uneven distribution, improved the finished product efficiency and the finished product quality of product.

The utility model has the advantages that:
