Specific embodiment
The Process Unit of U-tube group, by workbench 1, the briquetting 2, bent pipe tooling I3, the bend pipe that are positioned for pipe fitting end
Frock II4 is constituted；The face of workbench 1 is provided with dowel hole 5 in the circle centre position of U-tube group bending circular arc, each dowel hole
Side on or side-lower be provided with briquetting pilot hole 6；The briquetting 2 is made up of the backing plate 2-1 of bottom and the pressing plate 2-2 on top,
Backing plate 2-1 sides upper surface is provided with tube seat 7, and pressing plate 2-2 sides lower surface is provided with the pipe coordinated up and down with the tube seat on backing plate
Groove 7, is also provided with briquetting pin shaft hole 8 on pressing plate, using briquetting bolt 9 by pressing plate and its under backing plate be pressed on workbench
On the briquetting pilot hole 6 in face, between pipe fitting end is pressed on the tube seat for coordinating up and down；Bent pipe tooling I includes support frame, a shaping
Wheel 10 and two rollers 11, support frame by train wheel bridge 12, lower plate 13, be fixed on upper lower plate side and positioned at upper lower plate it
Between connecting tube 14 constitute, shaping wheel 10 is positioned between upper and lower clamping plate by bolt 15, and makes the arc wheel of shaping wheel
Face is corresponding with the tube seat front and back position on pressing plate and backing plate, the dowel hole that bolt 15 is positioned on workbench face simultaneously
Bent pipe tooling I is set to be positioned at workbench face in 5, two rollers 11 are positioned between upper and lower clamping plate by bearing pin 16 respectively,
And enable the arc wheel face of the arc wheel face of two rollers and shaping wheel while holding tightly in pipe fitting；The structure and bend pipe of bent pipe tooling II
Frock I is identical.
Application method is as follows（As shown in Figure 1）：
1st, the two ends of whole straight tube are processed into welding groove, and removes greasy dirt, iron rust, to facilitate the continued access of straight tube.
2nd, the connecting tube 14 of bent pipe tooling I is pulled, support frame and two rollers thereon are rotated around alignment pin, make connection
Straight tube vertically downward, is penetrated the shaping wheel of swan neck system I and the arc wheel face of two rollers by pipe, and tube head is clamped, connected by briquetting
Sleeve pipe is put on pipe, arm strength is lengthened, connecting tube is pulled upwards by hand, support frame drives roller around curved needed for shaping wheel rotation one
Bent angle, completes bending for first U-bend.
3rd, after the completion of first U-bend, should not be moved on curved position eventually, swan neck system is assembled at second U-bend
II, when second U-bend shapes substantially, the connecting tube of swan neck system I is return into beginning curved position, continue to pull swan neck system II
It is fully formed second U-bend.
4th, pull down swan neck system I and be assemblied in the 3rd U-bend position, carry out bending for the 3rd U-bend, until whole U
Shape pipe group is completed.
In order to the roundness deviation and trommel rate that ensure U-bend are controlled in tolerance, the arc wheel of shaping wheel 10
It is a circular arc that face uses straight transitions, the i.e. center section of arc wheel face between bicircular arcs structure, circular arc, and its two ends is identical
Another circular arc, straight transitions between circular arc；During specific implementation, the arc radius of center section are 10.5mm, the circular arc at two ends
Radius is 12.6mm, and the center of circle of two circular arcs is at a distance of 3.5mm.It is convenient disassembly, springback capacity is considered during shaping wheel design, and in processing
Remove 1/4 arch after shaping and lack 17；As shown in Fig. 9,10, after pipe bends shaping, after shaping is taken turns into rotated ninety degrees, due to
The scarce presence of arch, can smoothly dismantle shaping wheel.
