Description

A kind of automatic tube expanding machine

Technical field

The utility model relates to a kind of electric tube expander, relates in particular to a kind of heat-exchange tube 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.When 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 utility model, for deficiency of the prior art, provides a kind of automatic tube expanding machine, not only can excise the heat-exchange tube damaging separately in heat exchanger, can also carry out expand tube and reaming work to the heat-exchange tube of changing.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 utility model is solved by following technical proposals: a kind of automatic tube expanding machine, comprise stand and controller, on described stand, be disposed with first workbench, material table and second work stage, on described first workbench, be provided with first chute, on described first chute, be provided with mobile edition, on described stand, be provided with the first matching with described mobile edition and move cylinder, on described mobile edition, be provided with shifting chute, on described shifting chute, be movably set with telescopic mast, on described mobile edition, be also provided with the second matching with described telescopic mast and move cylinder, on described material table, be provided with several movably first positive stops, described material table side is also provided with some catch, 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 and the third 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 pipe-expanding device, on the third described 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 by first positive stop left and right, fixes heat exchanger.At this moment allow controller control the U-shaped junction that telescopic mast on mobile edition slides into problematic heat-exchange tube, the telescopic mast that then raises, allows telescopic mast snap into U-shaped junction.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, with pipe installation, cut and fitted tightly problematic heat-exchange tube on fin, after cutting, controller is controlled telescopic mast and is moved, and the heat-exchange tube being now cut open is pulled out by telescopic mast.Then in heat exchanger, insert new heat-exchange tube.After having inserted, allow controller control telescopic mast and prop up new heat-exchange tube bottom.This Time Controller is controlled second electric cylinder and is aimed at new heat-exchange tube by the pipe-expanding device on second falsework, then under the effect of pipe-expanding device, new heat-exchange tube is carried out to expand tube work.Last controller is controlled second electric cylinder allows the Counterboring apparatus on the third falsework aim at new heat-exchange tube, then under the effect of Counterboring apparatus, new heat-exchange tube is carried out to reaming work.

In technique scheme, preferably, described pipe installation comprises that pipe cutter and first push cylinder, described pipe cutter top is taper, on described pipe cutter, be provided with blade and several elastic components, the even circle distribution of elastic component described in several is on described pipe cutter, and described elastic component is than the more close described pipe cutter top of described blade.Arrange like this, in the Pipe Cutting course of work, the most important thing is that blade can not switch to the fin fitting tightly with heat-exchange tube, on pipe cutter, be provided with the elastic component of a circle for this reason, in the process that these elastic components are advanced at pipe cutter, there is the effect of supporting hot exchanging tube inside, first allow these elastic components guarantee that whole heat-exchange tube inside can not be out of shape, then blade cuts again, and blade just can not touch fin in the process of cutting like this, just can not cause damage to fin.

In technique scheme, preferred, described elastic component is provided with arc-shaped transition towards the one end at described pipe cutter top.Arrange like this, can facilitate elastic component to enter heat-exchange tube inside.

In technique scheme, preferred, described pipe-expanding device comprises that expander roll and third pushes cylinder, and described expander roll top is taper.Arrange like this, when expand tube, expander roll carries out expand tube operation to the heat-exchange tube of new insertion under the effect of the third propelling movement cylinder.

In technique scheme, preferred, on described first positive stop, be provided with elastic device.Arrange like this, on first positive stop, elastic device is set, prevent the fin on first positive stop infringement heat exchanger.Elastic device can be rubber conventionally.

In technique scheme, preferred, described Counterboring apparatus comprises that reaming head and fourth push cylinder.Arrange like this, when reaming, fourth pushes cylinder propelling movement reaming head the heat-exchange tube of new insertion is carried out to reaming work.

Compared with prior art, the beneficial effects of the utility model are: not only can excise the heat-exchange tube damaging separately in heat exchanger, can also carry out expand tube and reaming work to the heat-exchange tube of changing.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.
