Specific embodiment
As shown in Figs 1-4, a kind of pipe straightener, including base 1, base 1 include bottom plate, and bottom plate lower end side is equipped with
The movable supporting legs of retractable support are carried out by hydraulic cylinder 20, the bottom plate lower end other side is equipped with fixed supporting leg 21, and fixed supporting leg 21 is straight
It connects and is made into one molding using angle steel, can not be stretched.It sets with supporting leg face position there are four guide rod 3, leads above base 1
3 lower end of bar is thick, upper end is thin.2 surrounding of support frame pass through guide rod 3 and with 3 clearance fit of guide rod, support frame 2 can glide on guide rod 3
It is dynamic.Compressed spring 4 is equipped on the guide rod 3 of about 2 support frame, when support frame 2 moves up and down, compressed spring 4 is to support frame 2
It is buffered.
Support frame 2 includes hollow frame and the crossbeam 14 that intermediate lateral is arranged.On hollow frame along its length
It is fixedly welded with multiple groups stainless steel heating tube 5, when support frame 2 moves up and down, heating tube 5 is also with moving up and down.Stainless steel
5 outer wall of heating tube is wound with heater strip, and heater strip is connect with high-frequency induction heating machine (is not drawn into heater strip, high-frequency induction in figure
Heater).It is worked by high-frequency induction heating machine so that stainless steel heating tube is maintained under certain condition of high temperature.
Rotating inner tube 6, interval and needs between heating tube 5 and rotating inner tube 6 are jacketed in stainless steel heating tube 5
The steel pipe thickness of correction is adapted, only more bigger.Elasticity is equipped in rotating inner tube 6, close to 6 both ends open portion of rotating inner tube
Support frame 7.Flexible supporting frames 7 include the fixing seat 16 that is arranged in 6 end of rotating inner tube, set out that there are four logical in fixing seat 16
Hole 17, each 17 inner bottom surface of through-hole are connected with adjustment spring 18, and adjustment spring 18 is connect with the mandril 19 in through-hole 17, mandril 19
The other end stretches out fixing seat 16, rotating inner tube 6 and withstands on 5 inner wall of heating tube and (withstand on steel pipe after steel pipe protrudes into).
19 top of mandril is the arcwall face being adapted with steel pipe inner wall, and side has a small inclined-plane, small inclined-plane
Lower end is directed toward steel pipe input end, first and small oblique in this way when steel pipe is inserted into the interval between heating tube 5, rotating inner tube 6
The lower end in contact in face, facilitates transition to slide into, and mandril 19 is gradually moved into rotating inner tube 6.
Here mandril 19 uses Ru-Fe-Mn, and Ru-Fe-Mn is strong magnet, and after steel pipe indentation, rotation is stretched out in 19 end of mandril
6 outer wall 1mm-2mm of inner tube, and 19 top of mandril is equipped with arcwall face, such 19 top of mandril can also carry out absorption fixation with steel pipe.
Firm in order to guarantee to adsorb, flexible supporting frames 7 here may also set up multiple groups.Here 6 surface of rotating inner tube
Magnetic absorption layer can be coated, reinforce adsorbing and keeps being connected with the steel pipe of insertion.
Mandril 19 can be withstood on heating when steel pipe is not inserted into, through 18 elastic force of adjustment spring by flexible supporting frames 7 here
On pipe 5, and then rotating inner tube 6 is supported；When steel pipe insertion, the mandril 19 of flexible supporting frames 7 withstands on steel pipe and inhales
Attached fixation, so that rotating inner tube 6 is connected with steel pipe 22.
The rotating inner tube 6 is inserted into one end far from steel pipe and connect with first rotating shaft 8, and 8 other end of first rotating shaft passes through bearing
It is mounted on the bearing block 9 of base 1.First gear 10, the first tooth in each shaft 8 are mounted in each first rotating shaft 8
10 intermeshing of wheel；Intermediate 8 one end of shaft is stretched out bearing block 9 and is connect with motor 15.
Start motor 15 when, due to each first gear 10 be intermeshed, can drive in this way connect with first rotating shaft 8 it is each
A rotating inner tube 6 rotates.And rotating inner tube 6 is adsorbed by flexible supporting frames 7 and the steel pipe of insertion and is fixed, and in this way may be used
Steel pipe is driven to rotate together.
Multiple second shafts 11 are installed, 11 one end of the second shaft is mounted on axis by bearing below the first gear 10
It holds on seat 9, the other end is mounted on the side plate of base 1 by bearing, and such second shaft 11 can be rotated relative to base 1.Every
Second gear 12, cam 13 are equipped in a second shaft 11, wherein second gear 12 is engaged with first gear 10, cam 13 with
The crossbeam 14 of support frame 2 is in contact, and is supported to support frame 2.When first gear 10 rotates, will be moved by second gear 12
Power passes to the second shaft 11, and the cam 13 in the second shaft 11 rotates, since cam 13 is diameter-changing wheel, 13 center of cam
Distance to 14 contact point of crossbeam changes.In 13 rotary course of cam, the supporting point that crossbeam 14 is subject to is moved up and down, because
This support frame 2, which moves up and down, to be vibrated.By the rational design to cam 13, the severe degree of vibration can be changed.
When work, by the steel pipe of steel pipe 22(here only slight bending or surface bulge or recess) be inserted into heating tube 5,
It (when steel pipe has certain bending, can be tapped by tup, carry out pre-adjustment) in interval between rotating inner tube 6.In rotation
The mandril 19 at 6 both ends of pipe stretches out, and adsorbs and fix with steel pipe 22.High-frequency induction heating machine is opened, heating tube 5 is added
Heat opens motor 15 after heating tube 5 is heated to certain temperature, and 15 one side of motor is driven all by first gear transmission
Rotating inner tube 6, steel pipe 22 rotate together, 15 another aspect of motor by second gear 12 with moving cam 13 rotate, cam 13
It drives support frame 2 and is vibrated up and down with the fixed heating tube 5 of support frame 2.Steel pipe 22 rotates on one side in this way, is heated on one side,
About 5 heating tube vibrated up and down simultaneously during heating taps.Since the steel pipe 22 after heating is more advantageous to aligning, and
In 6 vibration processes of rotating inner tube, steel pipe 22 is constantly impinged upon on 5 inner wall of 6 outer wall of rotating inner tube and heating tube, so either
Hettocyrtosis deformation or local dent protrusion are all conducive to fast quick-recovery, and reduce internal stress deformation.
1 lower end of base is equipped with supporting leg, is wherein hydraulic cylinder 20, separate close to the supporting leg of steel pipe input end on base 1
The supporting leg of steel pipe input end is fixed supporting leg 21.By front end, telescopic outrigger is set, it, can be by by liquid when needing to take out steel pipe
Cylinder pressure 20 is shunk, so that on base 1 diagonally downward close to steel pipe input end, steel pipe 22 is acted on by fixture, by steel pipe
22 pull out.Here in design, heating tube 5, the length of rotating inner tube 6 are smaller than steel pipe 22, and the later period is facilitated to pull out.
