Description
Technical field
The present invention relates to one and take out pipe electric tube expander, relate in particular to a kind of heat-exchange tube and take out pipe electric tube expander.
Background technology
In heat exchanger production process, several metal tubes and suit fin thereon closely need to be combined, at this moment just need to carry out expand tube work to metal tube, allow metal tube diameter swell, make it closely to tie with fin, avoid producing and become flexible, increase the heat conductivility of heat exchanger, so just can guarantee good heat transfer and heat conduction.The operation of most expand tube all adopts automatic expand tube, and the fast efficiency of expand tube speed is high automatically, is applicable to producing in enormous quantities.In the time of expand tube, can cause part pipeline to occur flaw, such as pipe breakage, distortion; After this thing happens, often whole product all must be scrapped, and has caused very large loss.In order to reduce the loss, damaged pipeline can be released separately, then insert new pipeline, finally again this pipeline is carried out to independent expand tube.If manually carry out such operation, intensity is large, and efficiency is low, and is very easy to fin to cause damage, has so just caused thoroughly scrapping of heat exchanger.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of fast automatic pipe electric tube expander of taking out is provided, can automatically complete the Pipe Cutting of the interior heat-exchange tube damaging separately of heat exchanger, the work of taking out pipe, replace tubes, expand tube, solve interior certain heat-exchange tube of heat exchanger in the past and damaged the problem that rear whole heat exchanger will be scrapped.Also solved artificial replace tubes inefficient operation, more had the problem of the heat exchanger miscellaneous part that can be damaged simultaneously.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of fast automatic pipe electric tube expander of taking out, comprise stand and controller, on described stand, be disposed with first workbench, knife rest, material table and second work stage, on described first workbench, be provided with first chute, on described first chute, be provided with movably material frame, on described material frame, be provided with feeding cylinder, on described stand, be provided with the first electric cylinder matching with described material frame, on described material table, be provided with several movably first positive stops, described material table side is also provided with some catch, on described knife rest, be provided with electric chopper, in described second work stage, be provided with second chute, the mobile townhouse falsework that is provided with on described second chute, described townhouse falsework comprises the first falsework being arranged side by side, second falsework, the third falsework and fourth falsework, in described second work stage, be also provided with the second electric cylinder matching with described townhouse falsework, on described first falsework, be provided with pipe installation, on described second falsework, be provided with and take out pipe device, on the third described falsework, be provided with pipe-expanding device, on described fourth falsework, be provided with Counterboring apparatus.
Arrange like this, because the distance between the size of heat exchanger and the heat-exchange tube in heat exchanger is all confirmable, can first the range data between the size of these heat exchangers and heat-exchange tube be input in controller.In use, problematic heat exchanger is put on material table, then fixes heat exchanger by first positive stop left and right.Cut away the pipe U-shaped junction of problematic heat exchange by controller control electric chopper again, then controller control second electric cylinder drives townhouse falsework to move at second chute again, so just can make the pipe installation on the first falsework on townhouse falsework aim at problematic heat-exchange tube on material table.After aligning, cut and fitted tightly problematic heat-exchange tube on fin with pipe installation, then controller control second electric cylinder is aimed at the heat-exchange tube after cutting by the pipe device of taking out on second working lining, by taking out pipe device, the heat-exchange tube after cutting is extracted out.Material frame on this Time Controller control first workbench is aimed on heat exchanger vacant breach, heat-exchange tube new on material frame is pushed in heat-exchange tube under the effect of feeding cylinder, has pushed rear feeding cylinder and has not replied but prop up new heat-exchange tube always.This Time Controller control second electric cylinder allows the pipe-expanding device on the third working lining aim at new heat-exchange tube, then under the effect of pipe-expanding device, new heat-exchange tube is carried out to expand tube work.Last controller control second electric cylinder carries out reaming work by the Counterboring apparatus on fourth falsework to new pipeline.
