Abstract
A device for forming inside three-dimensional finned tube by multi-edge ploughing and extruding, comprises a machine frame, a machine head, a supporting mechanism, an axial feeding mechanism and a cutter assembly for forming inside fins. The machine head, the supporting mechanism and the axial feeding mechanism are axially mounted on the machine frame in sequence. The cutter assembly for forming inside fins is mounted on the feeding mechanism. One end of a metal tube to be machined for forming inside three-dimensional fins is clamped on a chunk of a rotary main shaft of the machine head, and the other end thereof is placed on the supporting mechanism. The rotary main shaft of the machine head provides the rotation power for the metal tube, and the axial feeding mechanism drives the cutter assembly to move linearly along a coaxial line of the metal tube and the cutter assembly.
