Abstract
The invention discloses a method and a device for processing a copper tube with a spiral rib fin. The method comprises a step of conveying a copper tube on a machine tool and a step of carrying out spiral rib fin processing on the copper tube by using a three-wheel rolling mill in the process of conveying; and the method is characterized in that the step of conveying a copper tube on a machine tool is implemented through sleeving the copper tube on a stainless steel round tube firstly, wherein the head part of the stainless steel round tube passes through the three-wheel rolling mill, then placing the copper tube and the rear section of the stainless steel round tube in the middles of three cylindrical poles which are arranged on the inlet side of the three-wheel rolling mill, stacked in a triangular shape and dead against an inlet of the three-wheel rolling mill, and leading the copper tube into the inlet of the three-wheel rolling mill so as to carry out spiral rib fin processing on the copper tube, wherein while a hob of the three-wheel rolling mill forms a spiral rib on the external surface of the copper tube through rolling, an axial force is also applied to the copper tube so as to push the copper tube to carry out axial movement along the outlet direction of the three-wheel rolling mill, in such a way, the copper tube is processed into a copper tube with a spiral rib fin. Compared with the prior art, the method and device disclosed by the invention have the advantages that the jumping of copper tubes can be prevented, the heights of spiral ribs are consistent, and the processing requirements of copper tubes with different lengths can be adapted.
Description
Technical field
The present invention relates to a kind of production method with copper tube with fins and device.
Background technology
Along with the continuous progress of industrial technology, present industrial equipment moves towards efficiently gradually, energy-saving future development.Shell and tube exchanger has now been widely used in the different field such as petrochemical industry, chemical industry, power and refrigeration, is the common apparatus being in great demand, and the height of its heat transfer efficiency directly has influence on the efficiency of energy utilization of process or technique.
Screwed pipe, as a kind of enhanced heat transfer component, can replace light pipe to be assembled into the shell-and-tube heat exchanger of all size, has compared following characteristics: can increase heat transfer area, enhanced tube conducts heat with light pipe heat exchanger outward, improves total heat transfer coefficient; Corrosion resistance is good.And the quality of its surperficial spiral fin directly affects the heat transfer property of screwed pipe.Screwed pipe can form by rolling, rolling process is mainly to complete under three-wheel rolling mill, with special hobboing cutter in the rolling of copper pipe outer surface, in order to guarantee that its spiral fin fin processing can meet the demands, the deflection of copper pipe in acceptability limit, that the spiral fin of copper pipe distributes is clear, just must take necessary servicing unit to guarantee carrying out smoothly of its production.Compared with prior art, during most of machining, copper pipe circular runout is severe, easily cause copper pipe distortion and process the spiral fin that height differs, do not meet production requirement, and can only process qualitatively a kind of product that designs processing length, when the different copper pipe processings of change, when required spiral fin length is different, reset again various machined parameters, extremely inconvenient.
Summary of the invention
The present invention relates to a kind of man-hour that adds, can prevent the method and apparatus of processing spiral fin copper tube with fins of the processing request of that copper pipe is beated, spiral fin height copper pipe consistent, that can adapt to different length.
The method of processing spiral fin copper tube with fins of the present invention is to realize like this, comprise the transport process of copper pipe on lathe, three-wheel rolling mill carries out the process of spiral fin fin machining to the copper pipe in transport process, its special feature is that the transport process on lathe is that copper pipe is enclosed within to head through on the stainless pipe of three-wheel rolling mill, then, copper pipe is placed in to the triangular in shape that stack of that side of three-wheel rolling mill import together with the back segment of stainless pipe and faces the middle part of three cylinder clubs of three-wheel rolling mill import, copper pipe is imported to the import of three-wheel rolling mill copper pipe is carried out to spiral fin fin machining, the hobboing cutter of three-wheel rolling mill is in rolling copper tube outer surface spiral fin, also give axial force of copper pipe, having promoted copper pipe axially moves along the direction of three-wheel rolling mill outlet, thereby copper pipe processing is become to the copper pipe with spiral fin fin.
Owing to adding man-hour, copper pipe is limited by the clamping of stainless pipe and three cylinder clubs, therefore, effectively prevents that copper pipe from beating, and has guaranteed that spiral fin height is consistent, and can adapt to the processing needs of the copper pipe of different length.
Here, in order further to limit and to add man-hour, beating of copper pipe, the copper pipe that exports out from three-wheel rolling mill packs into the dome core of guide cylinder roller front end, guide cylinder roller is placed in the middle part that three-wheel rolling mill exports the triangular in shape that stack of that side and faces three cylinder clubs of three-wheel rolling mill outlet, guide cylinder roller is under the axial promotion of copper pipe, middle part along three cylinder clubs moves axially, and copper pipe is also moved axially along the middle part of three cylinder clubs under the guiding of guide cylinder roller.Like this, copper pipe is subject to respectively the clamping restriction of stainless pipe and three cylinder clubs and the restriction of guide cylinder roller in whole process, and copper pipe can not be beated.
Here, stainless pipe maintains static in the process of three-wheel rolling mill processing copper pipe.Like this, while just having prevented that stainless pipe from moving axially with copper pipe, affect the processing of copper pipe.
