Process equipment for integral ring-shaped finned tube and technique thereof

Abstract

The invention discloses a manufacturing equipment and technological method of entire ring-shaped fin tube, which comprises the following parts: multiple-station mutual-control fin pipe rolling device, operational device, synchronous feeding device, high-frequency heating device, cooling heat disposal device and electric control device, wherein the blank is supplied by starting feeding motor through declaration mechanism, bevel gear pair to anchor feeding head, whose surface is heat by high-frequency heater, the pipe-shaped blank is transmitted in the multiple-station mutual-control fin pipe rolling device, which is set in the non-lifting rolling mould to mould the blank, the cooling device reduces temperature for entire fin pipe, which proceeds heat disposal through heating disposal device.

Description

Technical field: [0001] The invention relates to the technical field of processing equipment for components of general heat exchange or heat transfer equipment, in particular to a processing equipment and a process method for integral annular finned tubes. Background technique: [0002] At present, the structure of the finned tubes produced is mostly in a spiral shape. It is made of elongated metal sheets with good thermal conductivity and welded to the metal tubes by winding methods, embedding methods, folding embedding methods and embedding welding methods. Together, a spiral-shaped finned tube is formed to improve heat exchange efficiency by increasing the area of ​​heat conduction. This method does not eliminate the gap between the two bodies well. This gap is the key to hindering heat exchange, so its The heat exchange rate has always been low, coupled with the insurmountable winding stress and the different expansion coefficients of the two bodies, the gap gradually in...

[0002] At present, the structure of the finned tubes produced is mostly in a spiral shape. It is made of elongated metal sheets with good thermal conductivity and welded to the metal tubes by winding methods, embedding methods, folding embedding methods and embedding welding methods. Together, a spiral-shaped finned tube is formed to improve heat exchange efficiency by increasing the area of ​​heat conduction. This method does not eliminate the gap between the two bodies well. This gap is the key to hindering heat exchange, so its The heat exchange rate has always been low, coupled with the insurmountable winding stress and the different expansion coefficients of the two bodies, the gap gradually increases until the two bodies are separated, so the service life is short; the method of embedded welding is adopted, although the use of titanium powder buried welding is higher than that of high frequency The welding is good, but the cost is expensive, the process is complicated, and the problem of gap resistance still exists
