Description

Technical Field

[0001] The utility model relates to the technical field of steel material processing, in particular to a steel structure part spraying production line. Background Art

[0002] Steel is an important basic material in the national economy. It is widely used and consumed every year. During the use and storage of steel, it is very easy to rust due to environmental influences. Therefore, after the steel is produced into steel structural parts, it needs to be sprayed with paint to prevent rust. With the increasing standardization and serialization of steel structural parts production, the spraying of steel structures has shifted from traditional manual spraying or semi-automatic spraying by mechanical equipment to fully automated spraying in production workshops. Due to the large size and complex structure of steel structural parts, the spraying requirements are high during the spraying process on the production line. Therefore, the utility model designs a steel structural parts spraying production line for spraying and rust prevention of steel structural parts. Summary of the invention
