In the effect of inner conical surface, alligator clamp can tighten, thus is clamped in by fixed length tubing on the plug sending tube core bar front end.
The front end of described bend pipe template A9.12 is semi-cylindrical and is installed with described semicircle mould A9.6, and semicircle mould A9.6 opens
Being provided with the half slot that the passage A9.14 with described fixed length tubing A14.1 docks, this half slot is opened from the side of semicircle mould A9.6
Beginning, behind the front side of semicircle mould A9.6, extend to the opposite side of semicircle mould A9.6, the rear end one of semicircle mould A9.6 becomes
Type has a thimble A9.10 extended back.Offer through hole in bend pipe template A9.12, thimble A9.10 through after through hole with described
Contiguous block A9.1 connects, thus is driven by thimble cylinder A9.18 together with contiguous block A9.1.
As shown in Fig. 2 to Fig. 4-1, described movable part includes a swing span A9.3, at least one bulb core bar A9.4, a bulb
Core bar cylinder A9.13.Described swing span A9.3 is hinged on the half of described bend pipe template A9.12 front end by vertical pendulum moving axis A9.7
Cylindrical portion (usually in the axial location at semi-cylindrical position), vertical pendulum moving axis A9.7 and described No. three drive mechanisms
A9.11 connects.Bulb core bar cylinder A9.13 and guide rail A9.29, bulb core bar A9.4 it is fixed with by sliding on swing span A9.3
Block A9.30 be arranged on guide rail A9.29 and bulb core bar A9.4 head towards described fixed length tubing passage A9.14 arrange,
The push rod of bulb core bar cylinder A9.13 is connected with slide block A9.30 by link A9.28, thus drives bulb core bar A9.4 edge
Guide rail A9.29 moves back and forth.
Described movable part also includes that a bend pipe auxiliary mould A9.27, this bend pipe auxiliary mould A9.27 are fixed on swing span A9.3
On, be positioned at the head side of bulb core bar A9.4, bend pipe auxiliary mould A9.27 offers at least one with bulb core bar A9.4 phase
The arcuate groove A9.27.1 adapted to.During bend pipe, bulb core bar is inserted in fixed length tubing, positions the inwall of fixed length tubing, bend pipe
Arcuate groove A9.27.1 on auxiliary mould A9.27 positions the outer wall of fixed length tubing, and auxiliary bulb core bar completes bend pipe.
As shown in Fig. 7 .1 to Figure 13, described bulb core bar includes bulb 1, bearing pin 2 and core bar 3, the left end system of described core bar
Having endoporus 35, be provided with spring 31 in endoporus, the left end of bulb is hemisphere 11, and right-hand member is cylinder 12, and cylinder 12 inserts
The endoporus of core bar is also hinged in endoporus by bearing pin 2.The described end sending tube core bar A9.19 is shaped with and the hemisphere of bulb 1
The 11 spherical concave surfaces adapted.
Further, in order to avoid cylinder 12 cylinder by spring left end hook and when avoiding bulb 1 to rotate occurs
Being affected by spring, the present invention is also provided with a columned push rod 34 between described cylinder 12 and spring 31.This push rod
Being slidably insert in endoporus 35, the diameter of push rod is more than the external diameter of spring, and the right-hand member of push rod is resisted against spring left end, push rod
Left end be resisted against cylindrical right side so that bulb rotate time, cylinder is that face contacts with rod diameter, it is ensured that move
Stability.
The cylinder upper right corner of described bulb is shaped with arc tangent plane 14, is provided with for hinged looping pit in the middle part of cylinder
13.The hole wall of described looping pit 13 is by an arc section C1 of 1/2nd circles, straightway L1, quadrant shape
No. two arc section C2, No. two straightway L2, No. three arc section C3 and No. three straightway L3 of quadrant shape are sequentially connected with
Loop constitute, an arc section C1, No. two arc section C2 and No. three arc section C3 radiuses are equal.
The left end of described core bar 3 offers for hinged pin-and-hole 32, and the downside of core bar left side is shaped with right angle incision 33.
The outer tangent plane 33.1 of right angle incision switches to bottom core bar at the axis of core bar left side always, and the interior tangent plane 33.2 of core bar is from interior
The inwall of hole left end cuts out, and is crossed to form right angle with outer tangent plane 33.1, the middle part of core bar 3 be arranged with one for against and buffer
The elastic tape A9.4.1 of fixed length tubing A14.1.After sending tube core bar to shift fixed length tubing onto alligator clamp position, bulb core bar first puts in
Fixed length tubing, during this, elastic tape can compress copper pipe, it is ensured that fixed length tubing contacts with the shaft shoulder sending tube core bar and (send pipe process to have
Inertia, when sending tube core bar to deliver to, fixed length tubing not necessarily contacts with the shaft shoulder, or fixed length tubing is the most different in size, rubber
Circle is all adapted to), shift fork is stirred alligator clamp again and is locked by fixed length tubing, bend pipe the most again.
As shown in Fig. 7 .1 and Figure 12, when the effect that axially and the most all do not stresses of bulb 1, bulb 1 centre of sphere and core bar
The left part end face of 3 is provided with distance of stretch out and draw back L (about 1.1～1.5mm), now bearing pin 2 and the circular circular arc C 2 in cannelure 14
Coordinate；
As shown in Fig. 7 .2 and Figure 10, when core bar insertion copper pipe 4 starts to carry out bend pipe along mould 5, bulb 1 only axis
During the stress effect of direction, spring 31 is compressed axially, and bulb 1 and core bar 3 occur sliding compression distance of stretch out and draw back L, until bearing pin 2 and ring
Circular circular arc C 1 in shape groove 14 coordinates；
As shown in figure 11, when bulb 1 only lateral forces effect, spring 31 radially suffers restraints generation amount of deflection, bulb 1 profit
With core bar 3, beat occurring with arc tangent plane and right angle incision, now bearing pin 2 is joined with the circular circular arc C 3 in cannelure 14
Close.
The operation principle of the present invention is:
1), after fixed length tubing A14.1 enters pipe bending mechanism, send pipe motor A9.8 and feed screw nut pair to drive and send tube core bar
The front end of A9.19 is inserted in the mouth of pipe of fixed length tubing A14.1 rear end, and promotes forward fixed length tubing to enter alligator clamp A9.16,
The front end of fixed length tubing protrudes horizontally up alligator clamp；
2) bulb core bar cylinder A9.13 promotes bulb core bar A9.4 stretch out and be inserted in the mouth of pipe of fixed length tubing front end；
3) shift fork cylinder A9.2 drives shift fork A9.15, stirs alligator clamp and travels forward, makes the front end of alligator clamp by the conical surface
The extruding of A9.24 and shrink, by the back end grip of fixed length tubing on the plug A9.19.1 sending tube core bar A9.19 front end；
4) swing span A9.3 coordinates semicircle at the drive lower swing 180 degree of No. three drive mechanisms A9.11, bulb core bar A9.4
The interlude of fixed length tubing A14.1 is bent into arc by mould A9.6；
5) after the circumference indexing assembly until automatic moulding machine drives fixture to the fixed length tubing front moving to bend, thimble
Cylinder A9.18 promotes thimble, semicircle mould A9.6 that the fixed length tubing bent is pushed fixture；
6) swing span A9.3, shift fork A9.15, send tube core bar A9.19 and thimble to reset, wait bend pipe next time.
In above-mentioned work process, each motor and cylinder all complete under industrial computer or PLC control system.
It is only the specific embodiment of the present invention finally it should be noted that listed above.It is clear that the invention is not restricted to
