Description

Technical Field

[0001] The utility model relates to the field of fastener processing, in particular to a fastener passivation cleaning device after thermal diffusion sherardizing. Background Art

[0002] Fasteners are essential components in mechanical engineering, primarily used to connect and secure two or more parts or components together to form a single unit. Widely used in a variety of mechanical and engineering applications, including vehicles, ships, railways, bridges, buildings, tools, instruments, meters, and supplies, fasteners are crucial for ensuring the proper functioning and performance of machinery and engineering structures. With the development of the manufacturing industry and technological advancements, the fastener industry is also undergoing continuous innovation and development. In the future, fasteners will place greater emphasis on improving performance, such as lightweighting, high strength, corrosion resistance, and high-temperature resistance, to meet the demands of increasingly complex and harsh working environments.

[0003] Thermal diffusion sherardizing of fasteners is a surface treatment technology that improves their corrosion resistance. The process is as follows: degreasing → shot blasting → sherardizing → vibration separation → shot blasting → grinding and cleaning → drying → passivation → water washing → water washing → water washing → sealing (drying at 120°C). During the passivation and water washing processes, fasteners must be constantly turned to ensure adequate contact with the passivation solution and washing water. Small fasteners can easily fall into the passivation and water washing tanks.

[0004] In order to prevent small-sized fasteners from falling into the passivation tank and the water washing tank during the passivation and water washing process, and to realize the continuous and automated operation of the passivation and water washing process, we have researched and designed a fastener thermal diffusion sherardizing post-passivation cleaning device.
