Abstract
The utility model relates to a plating hanger, which comprises a main frame body, a main hook arranged on the main frame body and a shelf which is fixed on the main frame body and is used to place a plating part. The plating hanger is characterized in that the plating hanger is also provided with a current dividing part which is arranged in a power line concentration zone under the plating state. The current dividing part can be a plurality of main baffles which are fixed on upright posts at both sides of the main frame body, can also be an auxiliary baffle fixed on the shelf, or an auxiliary cathode. Compared with the prior art, the current dividing part is additionally arranged, so the current in a high current zone can be dispersed into a lower current zone, thus the current at the edge of the plating part is dispersed and the coating thickness of the zone is reduced to avoid the result of edge burning of the plating part, and the defects of thinner coating thickness and yellowing in the lower current zone caused by inadequate current are avoided to finally assure the surface quality of the plating part.
Description
Technical field
The utility model relates to a kind of plating apparatus, specifically refers to a kind of Electropolating hangers that is used to hang plating piece.
Background technology
Electropolating hangers is a kind of device indispensable in the industry of electroplating, and it consists predominantly of a body frame body, be arranged on the main hook on the body frame body and be used for placing the rest stand of plating piece.During use, after placing plating piece on the rest stand, be inserted in the bath trough, and with Electropolating hangers as galvanized negative electrode, after leading to electric current between cathode and anode, electric force lines distribution synoptic diagram as shown in Figure 3 will occur, i.e. the distribution of power line in bath trough has the advantages that concentrate at two ends, the centre is on the low side.This is little for product simple in structure, that volume is little influence, and the plating piece complex-shaped to this, that appearance requirement is higher and the product area is bigger, in the time of then the plating piece edge can occurring because of chromium deposition electric current excessive occur burn phenomenon.But in the low current district, because chromium plates fully jaundice can not appear again then.As the radiator grid of automobile industry, after reality was electroplated, burning will appear in outer at an upper portion thereof flange, the phenomenon that then can occur turning to be yellow in the medial recess zone.So this series products often can't obtain surface quality preferably after electroplating with common Electropolating hangers.
Summary of the invention
Technical problem to be solved in the utility model is at present situation of the prior art, and a kind of Electropolating hangers that can guarantee the plating piece surface quality is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this Electropolating hangers includes a body frame body, is arranged on the main hook on the body frame body and is fixed on the rest stand that is used for placing plating piece on the body frame body, it is characterized in that: also be provided with the electric current position of splitter that is positioned at the power line concentrated area under the plating state.
Described electric current position of splitter can be for being fixed on a plurality of master shields on body frame body two heel posts, and each master shield is in the shape of the letter V, and opening is towards the side margins of described plating piece.Also can be for being fixed on the auxiliary baffle plate on the rest stand, this auxiliary baffle plate is positioned on the upper limb of plating piece middle part.Perhaps can be an auxiliary cathode; Is good in described auxiliary cathode lower end with the galvanic protection baffle plate that is provided with corresponding plating piece top edge; can utilize master shield, auxiliary baffle plate like this; the current shielding of high Current Zone can be fallen,, reduce to burn at this regional plating piece to disperse the electric current of high Current Zone.And, can reduce the electric current of high Current Zone equally by means of auxiliary cathode, avoid burning of plating piece edge.
As further improvement of the utility model, can also be provided with a plurality of web members that plating piece is linked to each other with rest stand on the described rest stand.This web member can adopt an auxiliary hook, connects like this and dismantles comparatively easily and fast.Can certainly adopt whipping such as wire.
Compared with prior art, because the utility model has been set up the electric current position of splitter, thereby the electric current of high Current Zone can be distributed to the low current district, so both divided the electric current that has dissipated the plating piece edge, reduce this regional thickness of coating, to avoid the empyreumatic phenomenon of plating piece product edge, avoided the low current zone because of the thickness of coating that electric current causes inadequately approaches partially, the defective of product jaundice simultaneously again, and finally guaranteed the surface quality of plating piece.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, this Electropolating hangers is used for electroplating radiator grid, main hook 11 that it includes a body frame body 1, be arranged on body frame body upper end and a plurality of rest stands 2 that are connected mutually with the body frame body, wherein, the shape of each rest stand 2 and the profile of plating piece are complementary, to be used for placing plating piece.The lower portion of each rest stand is provided with a plurality of location card base 21, location hook 22, in the present embodiment, is provided with five location card bases 21 and two location hooks 22, can utilize respectively to locate card base and location hook is located corresponding radiator grid.Simultaneously, the plating piece on adjacent rest stand is interfered mutually, and adjacent rest stand lays respectively at the forward and backward side of body frame body, sees also Fig. 2.
Be fixed with a plurality of master shields 3 that are positioned at the power line concentrated area under the plating state on two heel posts of above-mentioned body frame body 1 respectively, each master shield is designed to the V font, and opening is towards the plating piece edge.In the present embodiment, the opening of each master shield 3 is towards the both sides of the edge of radiator grid, and in order to cooperate the edge shape of radiator grid sidepiece, the opening direction of adjacent master shield 3 can be slightly different, so that have better shunting effect.
Simultaneously also be provided with two auxiliary baffle plates 4 that are positioned on the plating piece top edge on described rest stand 2, here, each auxiliary baffle plate 4 is positioned on the upper limb of radiator grid middle part.In addition; in order to have better shunting action, on hanger, also be provided with two auxiliary cathodes 5, the bottom of each auxiliary cathode is provided with galvanic protection baffle plate 51 respectively; each galvanic protection baffle plate is corresponding to the upper limb between radiator grid middle part and the sidepiece, to protect this regional surface quality.
In the present embodiment, also above-mentioned rest stand is provided with a plurality of auxiliary hooks 6 that plating piece is linked to each other with rest stand, utilize auxiliary hook 6, both can connect easily and quickly and dismantle, simultaneously can improve the magnitude of current that the unit plating piece passes through again, can improve the not enough situation of intermediate recess zone electric current of radiator grid, make the surface quality of plating piece better.
