Abstract

The utility model discloses a hang device which is suited to be used when pipe materials and rod materials are electroplated, and the hang device is composed of a main hook and an auxiliary hook. One side or both sides of the main hook is provided with the arm of the auxiliary hook which is fixed on the arm of the auxiliary hook, and the exterior surface of the hang device (expect the contact part of a hook and an electroplating part) is coated with insulating materials. Not only no coating is arranged on the hang device, power expenditure and metal can be efficiently reduced, but also the coating of an electroplating piece is guaranteed uniformly by using the hang device to electroplate.

Description

Electroplate hanger

The utility model is a kind of hanger of placing plating piece when electroplating, the Electropolating hangers that uses when particularly long plating piece of tubing, bar or angle steel equal length being electroplated.

When metallic substance is electroplated, generally plating piece is placed on the enterprising electroplating of hanger.Electropolating hangers promptly supports plating piece, plays the conductor effect again, and plating piece and external power are joined.At present, when the bigger plating piece of length (for example tubing, bar etc.) is electroplated, adopt upsiloid single hook tool usually.Plating piece is stuck on the hanger after placing, and joins by two point of contact and power supply, and in addition, this single hook tool exposes.So when using this hanger to electroplate, not only also be coated with layer of metal on the hanger, simultaneously again because plating piece has only two point of contact to link to each other with power supply, voltage skewness on the plating piece, particularly this phenomenon of irony plating piece to long is more serious, and makes the electroplated metal thickness of coating inhomogeneous.Therefore, adopt this hanger not only to waste big volume and electricity and metal, and metal plating is also even inadequately.

The purpose of this utility model is a kind of Electropolating hangers of design, particularly is applicable to tubing, the hanger of using when the long plating piece of bar equal length is electroplated.When adopting this hanger to electroplate, can not plate metal on the hanger and avoid unnecessary power consumption and metal consumption.Increase hanger and plating piece point of contact simultaneously, make longer plating piece also can keep equi-potential, during electric degree, current density is even, so the metal level that is plated on the plating piece is even.

The utility model is for achieving the above object; following two solutions have been taked; one; for preventing that hanger is coated with coating, hanger is carried out insulation processing, hanger except that with the plating piece contact part; all coat insulating material; for example insullac is coated protective layer, for example furane resin glass reinforced plastic again outside insulating material.Like this hanger when electroplating except that and the point of contact of plating piece and non-conductive between the electroplate liquid, avoided electrical loss effectively.Its two, hanger is changed into main hook and is paid hook by common list hook.According to the length of plating piece, at a side of main hook or pair clevis arm of two sides design suitable length, to pay hook and be fixed on the clevis arm, clevis arm is to be made by the good electro-conductive material sheet brass of elasticity.When installing one when tackling hook, make and pay hook a little more than main hook, when plating piece is put on the tenaculum,, will pays hook and depress by the deadweight of plating piece, main hook is all contacted with plating piece with paying to link up with.In addition, the shape of hook has also been done design, hook changes the hook similar to the plating piece cross-sectional shape into, for example tubing, bar has been established the arc hook, and each hook and plating piece point of contact are increased, and sets up hook again.So promptly reduced the contact power consumption, made longer plating piece body keep equi-potential again, made the plating piece overlay coating even.

Hanging tool structure of the present utility model gives further instruction by embodiment.

Embodiment

Fig. 1 is a kind of hanger that is used for tubing or bar plating piece of the utility model design.

Among the figure, 1 hanger main body; 2 conductive seats; 3, main hook; 4 pairs of clevis arms; 5 pairs of hooks.

Wherein the hanger main body 1, main hook 3, and paying hook 5 is to be made by copper coin (electrolytic copper).Conductive seat 3, paying clevis arm 4 is to be made by the elasticity sheet brass, pays hook plane, 5 place for 2 and is higher than main hook 3 place plane 2～5mm.Except that hook and plating piece contact surface, all coat insullac earlier, coat furane resin glass reinforced plastic then.Design two-layer hook among Fig. 1, can design the multilayer hook according to actual needs, improved work efficiency.

Use this hanger, tubing or bar and hanger have 3 contacts site, have reduced contact resistance, make plating piece distribution of current when electroplating even again, and hanger itself has avoided plating metal again simultaneously, reaches the purpose of this utility model.In addition,, can design the hook of other shape, make hanger adapt to various plating pieces and use with length according to the difference of plating piece shape.

Claims

1, a kind of hanger used when being suitable for plating pieces such as tubing, bar and electroplating, feature of the present utility model is:

1) hook of hanger is linked up with two kinds by main hook with paying, and the clevis arm of paying of suitable length is arranged in the main hook one or both sides, pays to link up with to be fixed on and pays on the clevis arm;

2) hanger except that with plating piece part all be coated with insulating material.

2, according to the described hanger of claim 1, it is characterized in that the shape of linking up with is similar to the cross-sectional shape of plating piece, for example tubing or bar are adopted the arc hook.

3, according to the described hanger of claim 1, it is characterized in that its hook can be an individual layer, also can be designed to the multilayer hook.
