Description

Technical Field

[0001] The present application relates to the technical field of forging processing equipment, and in particular to a device for treating oxide scale of forging blanks. Background Art

[0002] The oxide scale of forgings is a layer of oxide film formed when the metal surface reacts with oxygen or an oxidizing medium during forging or heat treatment. During forging or heat treatment, metal at high temperature is more likely to react with oxygen, thereby forming an oxide scale on the metal surface. This oxide scale may have an adverse effect on the performance of the metal, such as reducing the corrosion resistance and fatigue strength of the metal. Therefore, it is usually necessary to remove this oxide scale in the subsequent processing.

[0003] The prior art discloses an oxide scale cleaning machine, which includes a base and a water tank, a billet conveying assembly, a cleaning box, a water collecting tray and a pumping assembly arranged on the base. The billet conveying assembly is located below the cleaning box, and both ends of the cleaning box are connected to the billet conveying assembly. A plurality of high-pressure nozzles are arranged in the cleaning box, and the high-pressure nozzles are connected to the water tank through the pumping assembly. The water collecting tray is arranged below the cleaning box, and an oxide scale chute is connected to the water outlet of the water collecting tray. The oxide scale chute is arranged to be inclined downward, and a rotatable magnetic roller assembly is arranged between the water outlet and the oxide scale chute.

[0004] With regard to the above-mentioned related technologies, forgings usually need to maintain a high temperature during the forging process, and the oxide scale on the surface of the forgings needs to be cleaned repeatedly. The oxide scale on the surface of the forgings is cleaned by spraying water with a high-pressure nozzle, and it is necessary to wait for the temperature of the forgings to drop below a certain value to avoid affecting the physical properties of the forgings. The time waiting for the forgings to cool down is relatively long, which seriously affects the overall forging efficiency of the forgings. Utility Model Content
