Double-fin finned tube processing machine tool

Abstract

The utility model relates to the technical field of finned tube machine tools, in particular to a double-fin finned tube machining tool which comprises a body, the body comprises a tool body and an outer fin tool set, the outer fin tool set comprises a plurality of outer fin tool bits arranged in a circumferential array, and an inner fin tool bit is arranged in the center of the outer fin tool set and is cylindrical. At least one spiral protrusion is arranged on the outer side of the first end of the inner-wing tool bit, the second end of the inner-wing tool bit is arranged to be a connecting end, the connecting end is connected with a main shaft rod, the main shaft rod is rotatably installed on the lathe bed, and the end, away from the inner-wing tool bit, of the main shaft rod is connected with a driving piece which drives the inner-wing tool bit to rotate. Through synchronous action of the outer fin cutter set and the inner fin cutter head, the inner fin and the outer fin are generated on the two sides of the pipe, and the heat exchange efficiency of the finned pipe is improved.
