The utility model discloses the structure of adopting supplementary negative pole to rob electric current on supplementary cathode hanger has avoided the thick height of product electrogalvanizing iron local coating to avoid the follow-up cladding material of bending of connecting rod product to drop.
Description
Technical Field
The utility model relates to an electroplate hanger technical field, concretely relates to supplementary negative pole hanger.
Background
When galvanization iron is carried out on workpieces with hole end parts such as automobile connecting rods, the thickness of a coating in a high current density area of the workpiece is too thick due to uneven current density distribution of the workpiece, raw materials are wasted, and the coating falls off during subsequent processing of the workpiece.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the features of the following embodiments and examples may be combined with each other without conflict.
As shown in fig. 1-3, an auxiliary cathode hanger made of zinc-iron alloy with high corrosion resistance for an automobile connecting rod comprises a conductive main rod 1, a conductive branch rod 2 is arranged on the conductive main rod 1, an auxiliary cathode plate 3 for current robbery is arranged on the conductive branch rod 2, and a hook 4 for hanging a workpiece 6 with a circular hole is arranged on the outer side of the auxiliary cathode plate 3.
The pole length of the electrically conductive mobile jib of this embodiment is upwards just to be located the both sides of electrically conductive mobile jib 1 and be provided with the electrically conductive branch of at least a pair of symmetry, and the homonymy that lies in electrically conductive mobile jib in every pair of electrically conductive branch is provided with the electrically conductive branch of two symmetries, wherein, is provided with an auxiliary cathode board on the electrically conductive branch of two symmetries respectively.
Two auxiliary cathode plates on the two symmetrical conductive supporting rods are oppositely arranged at intervals, two hooks are reversely arranged, and the hooks are arranged in the middle of the auxiliary cathode plates.
The auxiliary cathode plate is a square auxiliary cathode plate, the auxiliary cathode plate is a rectangular auxiliary cathode plate, and the area of the auxiliary cathode plate is larger than the area of the upper projection of the workpiece on the auxiliary cathode plate.
The distance between the conductive support rods is ensured that the workpieces hung on the hook are not contacted with each other.
The upper end of the conductive main rod is also provided with a bent suspension hook 5. All the conductive support rods, the auxiliary cathode plate and the hooks are mutually fixed through screws.
When the device is used, a workpiece is hung on the hook through the round hole in the workpiece, then the conductive main rod and the workpiece are placed into the electroplating bath together, the anode plate 7 of the electroplating bath is connected with the anode of a power supply, the conductive strut is connected with the cathode of the power supply, the area of the increased auxiliary cathode is larger than that of a product, and due to the tip effect, the auxiliary cathode plate can preferentially rush current, so that the current density on the product is reduced. Because of the existence of the auxiliary cathode plate, the current from the anode plate to the high current density area of the workpiece is blocked by the auxiliary cathode, the current density is reduced, and the current density of the area of the product which is originally at a high potential is reduced. The adsorption of zinc and iron ions at the end part of the workpiece is reduced, so that the film thickness of the end part of the workpiece is reduced, and the subsequent processing bending of the workpiece is free from coating falling off.
The above embodiments are only intended to represent the concentrated embodiments of the present invention, and the description thereof is more specific and detailed, but it is not to be understood as the limitation of the scope 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 concept of the present invention, and all of them belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
