Description

Technical Field

[0001] This utility model relates to the field of carburizing treatment technology, specifically to a carburizing pretreatment device for fasteners. Background Technology

[0002] Fastener carburizing is a process that improves the surface hardness and wear resistance of metals by injecting carbon into them. This process significantly improves the performance of fasteners, making them more durable and extending their service life. As a result, the workpiece can withstand both large impacts and high friction and contact fatigue strength.

[0003] Before carburizing heat treatment, fasteners need to undergo surface cleaning and polishing to ensure that the carburizing agent can fully penetrate the surface. Existing ultrasonic cleaning equipment for fasteners generally uses a rotating basket type, which cannot thoroughly remove dirt and grease from the fastener surface, and it is difficult to clean blind holes, dead corners, and other areas of the fastener. The cleanliness of the fasteners after cleaning is low, which affects the subsequent carburizing process. Utility Model Content
