Steel pipe cutting device for manufacturing motor shell

The invention discloses a steel pipe cutting device for manufacturing a motor shell, and relates to the technical field of motor shell cutting processing equipment, the steel pipe cutting device comprises a cutting assembly which is arranged above an operation table and is used for cutting a steel pipe body and a clamping assembly which assists in clamping the steel pipe body in the cutting process; and the two clamping assemblies are symmetrically arranged above the operation table, each clamping assembly comprises a supporting frame fixed to the upper portion of the operation table, and a first C-shaped clamping plate is fixed to the upper end of each supporting frame. In the cutting treatment process of the steel pipe body, when the steel pipe body is completely cut into two groups, the two groups of cut steel pipe bodies are pushed to be away from each other through the separation assembly, and in the separation process, the outer sides of the ends of the cut steel pipe bodies are subjected to coping, deb
