Description
Technical Field
[0001] This utility model relates to the field of steel pipe processing technology, specifically a steel pipe bending machine. Background Technology
[0002] Steel pipe bending machines primarily use molds to apply pressure to steel pipes, causing them to undergo plastic deformation and thus achieving the purpose of bending. Different types of bending machines may employ different bending methods and mold structures, but the basic principles are similar.
[0003] Steel pipe bending often takes place in factory or external environments, where the surface of the steel pipe is often covered with sand, gravel, or iron filings.

Existing steel pipe bending machines cannot clean the steel pipe before bending, requiring manual cleaning in advance, which undoubtedly greatly increases the workload of the workers.
[0004] Based on this, a steel pipe bending machine is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
