Detailed description of the invention
The CNC tube bending machine of the present invention, as shown in Figures 1 to 4, include lathe 100, pay-off 200,
Left acute angle handpiece 300, right acute angle handpiece 400, servomotor and numerical control device 500.
Left acute angle handpiece 300 is arranged on the side of lathe 100 leading section, including: fixing axle 301, circle mould 302,
Pattern 303, pattern travelling mechanism, clamping 304, clamping travelling mechanism and bending arm；Fixing axle 301 is fixed
Being arranged in left acute angle handpiece 300, bending arm is rotatably mounted on head, is used for bending pipe fitting, preferably
Ground, bending arm is around fixing axle 301 rotary setting.
Preferably, circle mould 302 is arranged on fixing axle 301, and circle mould 302 determines curved according to the shape of self
The pipe fitting of different-diameter processed and the radius of bending；Pattern 303 is arranged on a left side with being dislocated with circle mould 302
In acute angle handpiece 300, pattern 303 is connected with pattern travelling mechanism, numerical control device 500 control pattern and run
Institutional adjustment itself and circle mould 302 between distance, coordinate with the round mould 302 being fixedly installed, play clamping with
Unclamp the effect of pipe fitting；Preferably, bending arm being additionally provided with clamping 304, clamping 304 runs machine with clamping
Structure connects, numerical control device 500 control clamping travelling mechanism and adjust the distance between itself and circle mould 302, rise
To clamping with unclamp the effect of pipe fitting, meanwhile, clamping 304 can be with bending arm rotary motion, curved for pipe fitting
System provides bending power；
The first slide rail 101, the second cunning of horizontally set extended longitudinally it is provided with in the upper plane of lathe 100
The lead-screw drive mechanism 103 of rail 102 and horizontally set.
Pay-off 200 is arranged on the first slide rail 101, servomotor driving can be along the first slide rail 101
Movable.Pay-off 200 is also connected with lead-screw drive mechanism 103, can be by lead-screw drive mechanism 103
Drive along the second slide rail 102 transverse shifting.Pay-off 200 also includes feed spool 201, and feed spool can be around it
Central axis rotates, and feed spool leading section is provided with clamp mechanism 202, and clamp mechanism is preferably triangle clamp machinery
Hands, pay-off 200 for being transported to suitable bending position by pipe fitting.
The architectural feature of right acute angle handpiece 400 is symmetrical with left acute angle handpiece 300, and it is with left acute angle handpiece 300 symmetrically
It is arranged on the opposite side of lathe 100 leading section.
When needs bend pipe fitting, being first contained in clamp mechanism by the straight tube that needs bend, clamp mechanism presss from both sides
Tight pipe fitting, starts machine, and pay-off 200 moves along the first slide rail 101, by the first bending point of pipe fitting
Delivering at circle mould 302, pattern travelling mechanism drives pattern 303 close to circle mould 302, joins with circle mould 302
Close, pipe fitting the right and left is being carried out spacing, play the effect helping tensioning pipe fitting, then run by clamping
Mechanism drives clamping 304 close to circle mould 302, coordinates with circle mould 302 and clamps pipe fitting, left acute angle handpiece 300
Rotated the radian of setting around fixing axle 301 by driven by motor, clamping 304 bending being pipe fitting provides bending
Power, bends pipe fitting；After first bending place completes, unclamping clamping 304 and pattern 303, pay-off 200 continues
Continuous by seesawing, deliver to the second bending point of pipe fitting, at circle mould 302, continue above-mentioned steps, complete
Second bending part bending, the like, complete the bending operation of pipe fitting.
In above step, in order to meet the needs bending pipe fitting, it is also possible to by feed spool 201
Rotation makes pipe fitting rotate a certain angle.
When completing when bending of pipe fitting in left acute angle handpiece 300, numerical control device 500 controls lead screw transmission machine
Structure 103 drives pay-off 200 to move laterally to the another side of lathe 100 along the second slide rail 102, joins
Close right acute angle handpiece 400 and complete bending of pipe fitting.
According to the bending machine of the present invention, bending of especially suitable air-conditioner exhaust pipe assembly.Following table is for using this
The CNC tube bending machine of invention bends the decomposition of movement of exhaustor, in the present embodiment, all curved to stand in numerical control
The rotation direction of each parts is illustrated by pipe machine head part to the visual angle that tail part is seen:
Wherein, after completing step 8, need pipe fitting is carried out next step 90 degree of bendings, now, due to
4th curved position of exhaustor is in the lower section of left acute angle handpiece 300, if continued under left acute angle handpiece 300 is carried out
90 degree of bending operations of one step, the 4th curved position of exhaustor can interfere with the fuselage sections of lathe 100,
Cannot bending.For avoiding problem above, need that exhaustor is changed a direction and bend, therefore pass through lead screw transmission
Mechanism 103 drives pay-off 200 to move laterally to the side of right acute angle handpiece 400 along the second slide rail 102,
Pipe fitting is placed in right acute angle handpiece 400, right acute angle handpiece 400 completes to bend.
It is illustrated in figure 5 the pipe fitting of welding fabrication, is illustrated in figure 6 employing CNC tube bending machine of the present invention and bends
The pipe fitting of molding, two pipe fittings size, angle are all consistent, are satisfied by the relevant of air conditioning system through dependence test and want
Ask.Compared with the tube manufacture mode of welding fabrication, use CNC tube bending machine of the present invention save 1 blanking,
1 molding, 1 bend pipe and 1 welding sequence, while improve work efficiency, improve the steady of pipe fitting
Qualitative, it is ensured that the crudy of pipe fitting.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
