Description

Technical Field

[0001] The utility model relates to an ultrasonic cleaning and drying device for metal parts. Background Art

[0002] Currently, many precision-machined metal parts require cleaning, including degreasing, chip removal, rust removal, oxide removal, and contamination removal. To meet these cleanliness requirements, manual cleaning and drying of parts is traditionally performed, a time-consuming, labor-intensive, and inefficient process. Manufacturers typically use cleaning machines to clean workpieces, but these cleaning procedures are cumbersome and often involve lifting castings from the water, often picking up oily residue floating on the surface. This causes secondary contamination, necessitating further cleaning and resulting in poor results.

[0003] Currently, drying and cleaning are performed separately, requiring workpieces to be dried in the drying equipment after cleaning. This post-drying process increases labor costs and fails to guarantee a good product appearance. After cleaning, workpieces must be left outside the drying oven for a period of time, which can easily cause rust, leading to unstable equipment processes and low efficiency. Utility Model Content
