The invention relates to the technical field of
electroplating production lines, in particular to an aluminum
alloy floor
copper-
nickel-
chromium electroplating production line and a production processthereof. The aluminum
alloy floor
copper-
nickel-
chromium electroplating production line comprises a pretreatment area, and the pretreatment area comprises an ultrasonic
degreasing tank, a first cleaning tank, an ash removal tank, a second cleaning tank, a
zinc precipitation tank and a third cleaning tank; spraying devices used for cleaning plated parts are arranged between the first cleaning tankand the ash removal tank and between the second cleaning tank and the
zinc deposition tank correspondingly, and a spraying device is also arranged on the side, away from the
zinc deposition tank, ofthe third cleaning tank; and each spraying device comprises a supporting frame and a spraying mechanism, each spraying mechanism comprises a spraying
pipe, a water pump and a clear water tank, and each spraying
pipe communicates with the corresponding clear water tank through the corresponding water pump. The production process specifically comprises the following steps of hanging, ultrasonic oilremoval, cleaning, ash removal, zinc
precipitation and the like. The spraying devices can spray the plated parts, so that oil stains and impurities attached to the surfaces of the plated parts are fully cleaned, the excellent cleanliness of the surfaces of the plated parts is effectively improved, and the good electroplating quality of the plated parts is guaranteed.
