Embodiment 1

[0029] Embodiment 1: An anodized hanger suitable for circular workpieces.

[0030] Such as Figure 1~Figure 4 As shown, the hanger of the present invention is mainly composed of an upper hanger 10 and a lower hanger 11. The upper hanger 10 and the lower hanger 11 have the same structure and are arranged symmetrically.

[0031] Such as Figure 1~3 As shown, the upper hanger 10 includes a main frame rod 1 and several hanging teeth 2 .

[0032] The main frame rod 1 is the carrier of the whole pendant, and is also an intermediate electrical conductor to ensure that the hanging tooth 2 is electrically connected with the anode rod, and it is a straight rod made of titanium alloy material. A fixed ring 4 is provided in the middle of the rod body of the main frame rod 1, and its inner diameter is greater than the outer diameter of the anode rod, and its central axis is perpendicular to the rod body of the main frame rod 1, and is used to be sleeved outside the anode rod to connect t...

Embodiment 2

[0038] Embodiment 2: A mounting method suitable for circular workpieces.

[0039] The inventive method comprises the following steps:

[0040] a. The anodized hanger suitable for round workpieces described in Example 1 is set.

[0041]b. Set the upper pendant on the upper rod body of the anode rod, and put the lower pendant on the lower rod body of the anode rod, so that the hanging teeth of the two pendants correspond one by one, and the arc grooves of the two pendants are opposite, and make the upper pendant The distance between the highest point of the arc section of the pendant and the lowest point of the arc section of the lower pendant is slightly greater than the diameter of the circular workpiece 9;

[0042] c. Pull the hanging teeth of the upper pendant upwards by hand, put the circular workpiece 9 between the arc-shaped grooves of the upper and lower hanging teeth, let go, the hanging teeth will rebound, and fix the circular workpiece 9, as Figure 4 As shown, the ...

Abstract

The invention relates to an anodic oxidation hanger suitable for a circular workpiece and a hanging method. The hanger comprises an upper hanging piece and a lower hanging piece; the upper hanging piece and the lower hanging piece are the same in structure, and are symmetrically arranged; the upper hanging piece includes a main frame rod and multiple hanging teeth; the hanging teeth are arranged on the main frame rod, and are arranged in parallel along the main frame rod; the main frame rod is a titanium alloy straight rod; a fixed ring for coating an anode rod is arranged at the middle part of the main frame rod; the hanging teeth are titanium alloy battens, the middles are straight plate sections, and two ends are arc sections; the middle parts of the straight plate sections are fixed on the main frame rod, so that the arc sections form cantilevers extending outwards; the arc radius of the arc sections is smaller than the radius of the circular workpiece; the radial sections of the arc sections are arched to form arc grooves for clamping the circular workpiece; and liquid discharge holes for discharging oxide liquid are formed in the highest points of the arc sections. The hanger can fix the workpiece through four points, is excellent in fixing effect, and can prevent the problems of indentations on the product surface caused by clamping and nonuniform oxidation.

Description

technical field [0001] The invention relates to an anodic oxidation hanger and a mounting method, in particular to an anodic oxidation hanger and a mounting method suitable for circular workpieces. Background technique [0002] The anodic oxidation process of aluminum alloy workpieces adopts the method of electrochemical oxidation. The aluminum alloy workpieces are placed in sulfuric acid solution to form a conductive loop system. Oxygen is precipitated on the cathode of the electrode, and ecological oxygen (O) is generated on the anode, and it is combined with the anode aluminum The surface of the profile is compounded to form a dense aluminum oxide film to improve the protection, decoration, insulation and corrosion resistance of the surface of the aluminum alloy workpiece. [0003] The process conditions required by the workpiece in the anodizing process are harsh, with high current density, high final voltage and high heat generation. In order to ensure that the tempera...
