Embodiment 1

[0034] The current micro-arc oxidation treatment is intermittent, and steps such as cleaning and oxidation are performed separately, resulting in low production efficiency and high energy consumption. Please refer to figure 1 , the present embodiment provides a continuous oxidation treatment system 100, including a conveying device 110, a cleaning tank 120, an oxidation tank 130, a spray tank 140, a immersion tank 150, and a closed tank 160, the cleaning tank 120, the oxidation tank 130, the spray The box 140 , the dipping tank 150 and the closed tank 160 are arranged in sequence, and the conveying device 110 is arranged on the top of the cleaning tank 120 , the oxidation tank 130 , the spray tank 140 , the dipping tank 150 and the closed tank 160 . The conveying device 110 is used to convey the parts, so that the parts are continuously cleaned, oxidized, sprayed, soaked and sealed. This process is continuous and uninterrupted, reducing multiple operations on the parts, saving...

Embodiment 2

[0043] Please refer to image 3 , this embodiment provides a continuous oxidation treatment system 200 .

[0044] The difference between the continuous oxidation treatment system 200 and the continuous oxidation treatment system 100 mainly lies in:

[0045] The continuous oxidation treatment system 200 also includes a feeding area 210, a feeding area 220, a first draining area 230, a second draining area 240, and a third draining area 250. The feeding area 210 is arranged on a side of the cleaning tank 120 away from the oxidation tank 130. side, the unloading zone 220 is set on the side of the closed tank 160 away from the immersion tank 150, the first draining zone 230 is set between the cleaning tank 120 and the oxidation tank 130, and the second draining zone 240 is set between the oxidation tank 130 and the spraying tank 130. Between the tanks 140 , the third draining area 250 is disposed between the immersion tank 150 and the closed tank 160 . The processed parts are cl...

Embodiment 3

[0048] This embodiment provides a continuous oxidation treatment method, using a continuous oxidation treatment system 200 for oxidation treatment, including:

[0049] Set the moving speed of the conveying device 110 according to the time required for oxidation, and set the oxidation time and electrical parameters according to the material, surface area and application of the object. In the loading area 210 , the processing parts are clamped to the hanger 118 on the conveying device 110 , and the continuous oxidation treatment system 200 is started. Put the processed parts into the cleaning tank 120 and wash them for 1-2 minutes. After draining excess water in the first draining zone 230, they enter the oxidation tank 130 for oxidation for 10-30 minutes. After draining in the second draining zone 240, they enter the spray box 140 for cleaning ~ 2 minutes, then enter the immersion tank 150 for immersion for 1 ~ 2 minutes, drain the excess water in the third draining area 250, e...

Abstract

The invention provides a continuous oxidation treatment system and a continuous oxidation treatment method, and belongs to the technical field of light metal surface treatment. The continuous oxidation treatment system comprises an annular conveying device, an oxidation tank which is used for holding an electrolyte, and a conductive row which is matched with electrode contacts in a moving processof hanging tools; the conveying device is provided with a plurality of hanging tools; the hanging tools are used for fixing a part to be machined; and the electrode contacts are arranged on the hanging tools. The conveying device comprises a first conveying section, a descending section and an ascending section which are positioned above the oxidation tank; the descending section and the ascendingsection are respectively connected to a front end and a rear end of the first conveying section in a conveying direction so that the part to be machined enters the oxidation tank gradually when the part to be machined moves to the descending section along with the conveying device, and leaves away the oxidation tank gradually when the part to be machined moves to the ascending section; and the conductive row is arranged between the first conveying section and the oxidation tank. The system is simple in structure; the oxidation period is shortened; the production efficiency is high; and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of light metal surface treatment, in particular to a continuous oxidation treatment system and method. Background technique [0002] Micro-arc oxidation technology is a high-tech technology for in-situ growth of ceramic layers on the surface of aluminum, magnesium, titanium and other light metal alloys. The principle is to generate an anodized film on the surface of the workpiece, and at the same time convert the polarized film into a ceramic phase through a micro-arc instantaneous high temperature. The ceramic layer has high hardness, high wear resistance, good toughness, strong bonding force with the substrate, corrosion resistance, high temperature oxidation resistance, and good insulation. It is especially suitable for light metal alloys that move at high speed and require high wear resistance, corrosion resistance, and high temperature impact resistance. parts. The combination between the micro-arc ox...
