Description

Technical Field

[0001] The utility model relates to the technical field of anodizing devices, in particular to a sulfuric acid anodizing device. Background Art

[0002] Sulfuric acid anodizing refers to placing the metal workpiece to be treated as the anode in a sulfuric acid electrolyte. Under the action of a certain voltage and current, an oxidation reaction occurs on the metal surface to form a dense oxide film. Sulfuric acid anodizing equipment is widely used in the surface treatment of metal materials such as aluminum and aluminum alloys, magnesium and magnesium alloys, and can improve the metal's corrosion resistance, wear resistance, hardness and decorative properties.

[0003] The utility model patent with announcement number: CN220619156U discloses a sulfuric acid anodizing tank for aluminum and aluminum alloys. The tank body is composed of a lining lead plate, an insulating layer and a steel plate arranged in sequence from the inside to the outside. The two ends of the anode copper rod arranged at the slot position parallel to the length direction of the tank body are respectively adapted to the insulating seats at the corresponding positions. The cathode terminal in close contact with the two lining lead plates is fixed on the groove edge in the length direction of the upper end of the tank body, and the positive and negative poles of the power supply are respectively connected to the anode copper rod and the cathode terminal through a busbar or copper wire with sufficient load, forming a current circuit for sulfuric acid anodizing of parts hung on the anode copper rod through a hanger.

[0004] However, there are still certain shortcomings in the above technical solution: the above technical solution realizes the oxidation process by placing the workpiece on a hanger and then applying power. However, during this process, the workpiece remains stationary and the electrolyte also remains stationary. In this case, the electrolyte concentration will be uneven and the temperature will also be uneven, which will affect the oxidation effect. Therefore, the existing technical solution needs to be improved. Utility Model Content
