Description
Technical field
The present invention relates to a kind of expanding device of electric tube expander.
Background technology
Existing electric tube expander typically combines tube expanding mechanism with flaring mechanism, and heat exchanger workpiece needs first tube expansion,
Then enlarging again, relatively inefficient, and expansion head will be set on outside expander roll, and due to the limitation in space, the design for expanding head is present
Certain limitation, the quality to enlarging also has a certain impact, and it is hollow to expand head in addition, and its service life is relatively
It is short.Also what is had separates tube expansion and enlarging, and the quantity for expanding head is the row of workpiece, general single expansion head, double with regard to two
Individual expansion head, so needing multiple enlarging to complete the enlarging of whole heat exchanger workpiece, is especially expanding the mouth of pipe on workpiece both sides
When, workpiece unstability is easily caused because of discontinuity, so that there is the phenomenon of mouth of pipe rupture, it is therefore desirable to improve.
The content of the invention
The present invention seeks to solve the above-mentioned not enough of prior art and provide a kind of expanding device of electric tube expander, makes its enlarging
Efficiency high, workpiece uniform force, accurate positioning.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：The expanding device of electric tube expander, including bearing, expansion
Mouth seat, flare seat drive mechanism, enlarging template assembly, expansion head and its expansion head moving mechanism, flare seat is in seat supports, enlarging
Seat is moved up and down by flare seat drive mechanism on bearing, and enlarging template assembly is connected in flare seat, is expanded head and is connected to enlarging
On template assembly.
Preferably, guiding mechanism is set between bearing and flare seat, and such flare seat is more flat when being moved up and down on bearing
Surely.
Preferably, expansion head transverse moving mechanism is also set up, expands head transverse moving mechanism and drives enlarging template assembly laterally to move
It is dynamic, it can so change workpiece and the position expanded between head, so as to remove the workpiece for having completed flared part, move into also not complete
Into the workpiece portion of enlarging, so as to complete the enlarging work of whole workpiece.
Preferably, laterally steering mechanism is also set up between flare seat and enlarging template assembly, so can be more smoothly
Mobile enlarging template assembly.
Preferably, flare seat drive mechanism is arranged on the base of electric tube expander, and flare seat drive mechanism passes through force transmission mechanism
Driving flare seat is moved up and down, and such mechanism is more steady.
Preferably, above-mentioned expansion head is rotatably connected on enlarging template assembly and by that can drive the expansion head of expansion head rotation
Mechanism drives, and so expands head and carries out rotation enlarging, laborsaving and enlarging efficiency high.
Compared with prior art, the advantage of the invention is that：Due to the tube expanding mechanism of electric tube expander and flaring mechanism being separated,
Single flaring mechanism is set, multigroup expansion head can be set, and multigroup expansion head carries out enlarging work simultaneously, therefore substantially increases expansion
The operating efficiency of mouth, and multiple expansion heads move down enlarging simultaneously, improve the uniformity of enlarging, reduce because of multiple different enlargings
And the workpiece enlarging quality caused is unstable.

Fig. 2 is the side view that Fig. 1 removes electric tube expander fuselage.
Fig. 3 is the structural representation of another embodiment of the present invention.
Fig. 4 is the floor map of expansion head drive mechanism in Fig. 3.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in Figure 1 and Figure 2, the expanding device of electric tube expander, including flare seat 1, force transmission mechanism 2, flare seat drive mechanism 3,
Enlarging template assembly 4, guiding mechanism, expansion first 5 and its expansion head moving mechanism.
Above-mentioned flare seat drive mechanism 3 is arranged on tube expansion machine base 10, is connected by force transmission mechanism 2 with flare seat, is passed
Force mechanisms 2 drive flare seat to be moved up and down along the guide rail 4 on electric tube expander fuselage 11.
Above-mentioned expansion first 5 is arranged on the lower section of enlarging template assembly 4, and expanding first 5 can have multigroup, multigroup distance and work expanded between head
The pipe fitting for needing enlarging in part is consistent.
Above-mentioned expansion head moving mechanism includes motor 7, ball screw 8, feed screw nut 9, and motor 7 is arranged in flare seat 1, electricity
The output shaft of machine 7 is connected with ball screw 8, and the feed screw nut 9 being arranged on by support 14 on enlarging template assembly 4 is set on ball
Outside screw mandrel 8.When needing mobile expansion head, start motor 7, motor 7 drives ball screw 8 to rotate, ball screw 8 and feed screw nut 9
Cooperation makes the transverse shifting of enlarging template assembly 4, so as to change the position between the pipe fitting 17 for expanding first 5 and needing enlarging on workpiece below
Put, and displacement can accurately be controlled by ball screw.
Preferably, guiding mechanism is also set up between flare seat and enlarging template assembly, so can more smoothly be moved
Enlarging template assembly.
Above-mentioned guiding mechanism include be arranged on enlarging template assembly above slide 12 and it is corresponding be arranged on enlarging
Slide rail 13 below seat.
Fig. 3, Fig. 4 are another embodiment, and the drive mechanism of expansion head rotation can be made by being set on the expanding device of electric tube expander.
It is above-mentioned make enlarging rotate drive mechanism include motor 18, driving pulley 19, one group of drive pulley 20 and 21 with
And the belt wheel 22 on each expansion head, plan such as Fig. 4 is driven, motor driving driving pulley is rotated, the He of drive pulley 20
21 drive each belt wheel 22 expanded on head to rotate by transmission belt, so that expanding head rotation enlarging.
Sprocket wheel can be also changed to upper belt-wheel, realize that expanding head rotates by chain gear transmission.
During workpiece enlarging, flare seat drive mechanism can drive expansion head to move up and down by flare seat, complete to workpiece
Enlarging, after the completion of enlarging, the expansion head that enlarging template assembly and its lower section are installed is driven along cunning by expanding head moving mechanism
Rail is moved horizontally, so as to carry out the enlarging of the next group of mouth of pipe of workpiece, is thus circulated, and just can complete the enlarging work of whole workpiece
Make.
