Technical Field

The utility model relates to an electroplating hanger for cylindrical imperforate parts, belonging to the technical field of electroplating auxiliary equipment.

Background

Electroplating is a process of depositing a layer of metal or alloy on the surface of a plated part, common electroplating modes are barrel plating and rack plating, common non-porous parts are electroplated in a barrel plating mode, but parts collide with each other in the barrel plating process to cause part damage, and for parts with high appearance requirements or high surface smoothness requirements, the barrel plating mode cannot be adopted; the part needs to be fixed on a hanger in the rack plating process, generally, a clamp of the hanger extends into a hole of the part or the part is hung on the hanger, but when the part does not have the hole or hanging points, the part can only be hung and plated singly, and therefore the efficiency is low.

When the electroplating hanger of the LED support material belt disclosed in the Chinese patent No. 2014204138938 is used, because the movable clamping plate is solid, when a part is clamped, the movable clamping plate deforms and is clamped, multi-line contact exists, so that plating solution is difficult to flow onto the contact surface of the movable clamping plate and the part, and the surface smoothness of the appearance of the part after the rack plating is finished is reduced.
