Abstract
The invention provides a flaring device of a pipe expander. The flaring device comprises a support, a flaring seat, a flaring seat driving mechanism, a flaring template assembly, enlarged ends and an enlarged end moving mechanism, wherein the flaring seat is supported by a support; the flaring seat moves up and down on the support by the flaring seat driving mechanism; the flaring template assembly is connected onto the flaring seat; the enlarged end is connected onto the flaring template assembly. The flaring device of the pipe expander has the advantages that a pipe expanding mechanism of the pipe expander is separated from a flaring mechanism and an independent flaring mechanism is arranged; the plurality of sets of enlarged ends can be arranged and can carry out flaring work at the same time so that the working efficiency of the enlarged ends is greatly improved; the plurality of enlarged ends can be moved downwards at the same time to carry out flaring so that the flaring consistency is improved, and the instability of the flaring quality of a workpiece, caused by carrying out a plurality of times of flaring, is reduced.
Description
Technical field
The present invention relates to a kind of expanding device of electric tube expander.
Background technology
Existing electric tube expander is generally combined tube expanding mechanism and flaring mechanism, heat exchanger workpiece needs first expand tube, and then enlarging, efficiency is relatively low, and expand head to be set on outside expander roll, due to the restriction in space, the design of expanding head has some limitations, quality to enlarging also has a certain impact, and it is hollow expanding head in addition, and its service life is relatively short.What also have separates expand tube and enlarging, the row that the quantity that expands head is workpiece, general single one is expanded head, double expands head with regard to two, so need repeatedly enlarging just can complete the enlarging of whole heat exchanger workpiece, especially, in the time expanding the mouth of pipe on workpiece both sides, easily cause workpiece unstability because of discontinuity, to such an extent as to there is the phenomenon that the mouth of pipe breaks, therefore need to improve.
Summary of the invention
The present invention will solve the above-mentioned deficiency of prior art and expanding device that a kind of electric tube expander is provided, makes that its enlarging efficiency is high, workpiece is stressed evenly, accurate positioning.
The present invention solves the problems of the technologies described above adopted technical scheme: the expanding device of electric tube expander, comprise bearing, enlarging seat, enlarging seat driving mechanism, flaring die board component, expand head and expand head moving mechanism, enlarging seat is by seat supports, enlarging seat is moved up and down on bearing by enlarging seat driving mechanism, flaring die board component is connected on enlarging seat, expands head and is connected on flaring die board component.
Better, between bearing and enlarging seat, guiding mechanism is set, more steady when enlarging seat moves up and down on bearing like this.
Better, also arrange and expand a transverse moving mechanism, expand a transverse moving mechanism and drive flaring die board component transverse shifting, can change like this workpiece and expand the position between head, thereby remove the workpiece that completes flared part, move into and also do not complete the workpiece part of enlarging, thereby complete the enlarging work of whole workpiece.
Better, between enlarging seat and flaring die board component, laterally steering mechanism is also set, so more reposefully mobile flaring die board component.
Better, enlarging seat driving mechanism is arranged on the base of electric tube expander, and enlarging seat driving mechanism drives enlarging seat to move up and down by force transmission mechanism, and mechanism is more steady like this.
Better, above-mentioned expansion head is rotatably connected on flaring die board component and by making an expansion driving mechanism that expands head rotation drive, and expands like this and is rotated enlarging, laborsaving and enlarging efficiency is high.
Compared with prior art, the invention has the advantages that: due to the tube expanding mechanism of electric tube expander is separated with flaring mechanism, independent flaring mechanism is set, many groups can be set and expand head, many groups expand head and carry out enlarging work simultaneously, have therefore greatly improved the operating efficiency of enlarging, and multiple expansion head moves down enlarging simultaneously, improve the uniformity of enlarging, reduced unstable because of workpiece enlarging quality that repeatedly different enlargings cause.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
As shown in Figure 1 and Figure 2, the expanding device of electric tube expander, comprises enlarging seat 1, force transmission mechanism 2, enlarging seat driving mechanism 3, flaring die board component 4, guiding mechanism, expansion 5 and expands head moving mechanism.
Above-mentioned enlarging seat driving mechanism 3 is arranged on electric tube expander base 10, is connected with enlarging seat by force transmission mechanism 2, and force transmission mechanism 2 drives enlarging seat to move up and down along the guide rail 4 on electric tube expander fuselage 11.
Above-mentioned expansion 5 is arranged on flaring die board component 4 belows, and expanding 5 can have many groups, and it is consistent with the pipe fitting that needs enlarging in workpiece that many groups expand distance between head.
Above-mentioned expansion head moving mechanism comprises motor 7, ball screw 8, feed screw nut 9, and motor 7 is arranged on enlarging seat 1, and motor 7 output shafts are connected with ball screw 8, and the feed screw nut 9 who is arranged on flaring die board component 4 by support 14 is set on outside ball screw 8.While needing mobile expand, starter motor 7, motor 7 drives ball screw 8 to rotate, ball screw 8 coordinates with feed screw nut 9 makes flaring die board component 4 transverse shiftings, thereby change expand 5 with its below need the position between the pipe fitting 17 of enlarging on workpiece, and displacement can accurately be controlled by ball screw.
Better, between enlarging seat and flaring die board component, guiding mechanism is also set, so more reposefully mobile flaring die board component.
Above-mentioned guiding mechanism comprises and is arranged on the slide 12 of flaring die board component top and the corresponding slide rail 13 being arranged on below enlarging seat with it.
Fig. 3, Fig. 4 are another embodiment, and the driving mechanism that can make to expand head rotation is set on the expanding device of electric tube expander.
The above-mentioned driving mechanism that makes enlarging rotation comprises motor 18, driving pulley 19, one group of drive pulley 20 and 21 and be arranged on each and expand the belt wheel 22 on head, transmission plane is as Fig. 4, motor drives driving pulley to rotate, drive pulley 20 and 21 drives each belt wheel 22 expanding on head to rotate by driving-belt, thereby makes to expand head rotation enlarging.
Also can be changed to sprocket wheel with upper belt-wheel, realize and expand head rotation by chain gear transmission.
When workpiece enlarging, enlarging seat driving mechanism can drive expansion head to move up and down by enlarging seat, complete workpiece enlarging, after enlarging completes, drive the expansion head of flaring die board component and below installation thereof to move horizontally along slide rail by expanding head moving mechanism, thereby carry out the enlarging of next group mouth of pipe of workpiece, circulation, just can complete the enlarging work of whole workpiece thus.
