Problems solved by technology
At present, there are many kinds of cooling pipes on the market, with different shapes, but the most important ones are circular cooling tubes and oval cooling tubes. Because circular cooling tubes are regular tubes, they are simple and convenient to make, and are the most common and widely used. A kind of heat dissipation pipe. The biggest disadvantage of circular heat dissipation pipes is that the pipe has a large air resistance and low thermal efficiency; compared with circular heat dissipation pipes, the oval heat dissipation pipe has smaller air resistance and higher thermal efficiency.
Existing elliptical heat pipes have a single type, all of which are piercing type, that is, the fins are pierced and fixed on the elliptical inner tube along the circumference of the elliptical inner tube. , the fins and the oval inner tube are loose, which affects the thermal efficiency

The invention discloses a machining device for an elliptical rolling type radiating pipe. The machining device is characterized in that a workpiece transmission mechanism, a driving gear and a driven gear rotate synchronously; hob fixing seats are limited by the shape of an elliptical sleeve and move in the direction of guide shafts; the axial center lines of hobs and that of a to-be-machined elliptical radiating pipe are staggered for a certain angle, so that a workpiece drives the hobs to rotate; the rotating to-be-machined elliptical radiating pipe is extruded by the hobs to move axially; and finally, an elliptical spiral rolling layer is formed on the surface of the workpiece. The machining device is compact in structure, is high in control precision, and fills in the market gap in the elliptical rolling type radiating pipe.
Description
technical field [0001] The invention relates to the field of heat dissipation pipe processing equipment, in particular to an elliptical sheet-rolled heat dissipation pipe and a processing device thereof. Background technique [0002] As heat exchange equipment, radiator pipes are widely used in industrial production and heating engineering. At present, there are many kinds of heat dissipation pipes in the market, with different shapes, but the most important ones are circular heat dissipation pipes and oval heat dissipation pipes. Because circular heat dissipation pipes are regular pipes, they are simple and convenient to make, and are the most common and widely used. A heat dissipation pipe. The biggest disadvantage of the circular heat dissipation pipe is that the pipe has a large air resistance and low thermal efficiency; compared with the circular heat dissipation pipe, the elliptical heat dissipation pipe has a smaller air resistance and a higher heat efficiency.
