Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment 1:
As shown in Fig. 1 ~ 5, the tubular detection system of a kind of bend pipe, the control system (not shown) comprising CNC tube bending machine 1, tubular checkout gear and Detection Information is processed, in the present embodiment, tubular checkout gear is the sensor 11 of a measuring distance, as the sensor of laser ranging, this sensor 11 is arranged on CNC tube bending machine 1, with on the processing pipe fitting 8 place same plane on CNC tube bending machine 1, the output of this sensor 11 is connected to the input to the control system that Detection Information processes, and utilizes geometrical principle to calculate the spring back angle of pipe fitting 8.CNC tube bending machine 1 comprises frame 12 and head 10, frame 12 is provided with and is used for fixing, push the feeding trolley 2 of pipe fitting 8, this head 10 be provided with the main folder 4 that to coordinate with bending die 7 and clamp pipe fitting 8 and coordinate the auxiliary folder 6 clamping pipe fitting 8 with Anti-wrinkling board 3, frame 12 between feeding trolley 2 and head 10 is provided with the bracing or strutting arrangement 9 for support tubes 8, this bracing or strutting arrangement 9 makes whole pipe fitting 8 be in same level height all the time in process, in note bend pipe, the bending place of pipe fitting 8 is O point 83, this O point front is the A section 81 of pipe fitting, rear is the B section 82 of pipe fitting.
Can there be multiple choices the concrete installation site of sensor 11 on CNC tube bending machine 1, as: can be arranged near A section 81, it is the head 10 of CNC tube bending machine 1 near A section 81, due to rotary oscillation in head 10 operation, be arranged on the precision that head 10 can affect sensor 11, and head 10 narrow space, be not easy to install; And for example: can be arranged in main folder 4, what now sensor 11 was measured is the A section 81 of pipe fitting 8, and abnormity change can be there is in the A section 81 of bend pipe rear tubular member, changed by the distance compared between the normal pipe fitting before special piece and resilience and sensor 11, the result recorded like this can produce very large error, affects certainty of measurement; And B section 82 bend pipe terminates only to occur departing from overall angle, therefore on the preferred bracing or strutting arrangement 9 sensor 11 being arranged on pipe fitting B section 82 direction.This bracing or strutting arrangement 9, by the first Serve Motor Control (not shown), keeps motionless in bend pipe and tubular testing process, thus guarantees the accuracy of detection of sensor 11 mounted thereto.
The tubular testing process of bend pipe is as follows:
When pipe fitting 8 terminates bend pipe, the main folder 4 on head 10 and auxiliary folder 6 be clamping pipe fitting 8 still, and now the beeline S with pipe fitting 8B section 82 measured by sensor 11
1, feeding trolley 2 unclamps for clamping pipe fitting 8 pipe bundle clip subsequently, is retracted into the end rear with pipe fitting 8, thus be separated with pipe fitting 8, then unclamping auxiliary folder 6, there is resilience in pipe fitting 8, until resilience terminate rear tubular member 8 be in stable state time, then measure the distance S with pipe fitting 8B section 82 ＇ by sensor 11
2.By comparing the range data of twice, calculating spring back angle and the rebound degree of pipe fitting 8, feeding back to control system, thus in next is curved, springback compensation being carried out to bend pipe angle.
Account form as shown in Figure 5, first measures the beeline S of pipe fitting 8B section 82 in the clamp state and between sensor 11 before resilience
1, subsequently after resilience terminates, measure the distance S between pipe fitting 8B section 82 ＇ and sensor 11
2obtain the snap-off-distance a=S1-S2 of pipe fitting 8 thus, pipe fitting 8 is before and after resilience, distance b between O point 83 and sensor 11 measuring point remains unchanged, and distance long enough, be far longer than snap-off-distance, constituting a base is a, the long isosceles triangle for b of waist, and the θ now in figure is the spring back angle of pipe fitting 8.
Then geometrical principle is utilized to obtain the spring back angle θ of pipe fitting 8, as: according to the cosine law, when known Atria bar limit, cos θ=(b can be obtained
2+ b
2-a
2)/2b
2, therefore spring back angle θ=arccos (b
2+ b
2-a
2)/2b
2; And for example: cos θ=(b
2+ b
2-a
2)/2b
2,
therefore spring back angle θ=arctan (sin θ/cos θ) × 180/ π.And then the rebound degree ≈ spring back angle/desirable bend pipe angle of pipe fitting 8 is obtained according to this spring back angle, make system carry out springback compensation according to the rebound degree of this pipe fitting 8 man-hour in the next one curved adding, revise tubular.Geometrical principle in the present invention is not limited to the preferred embodiment provided in the present embodiment, and other carry out the distortion of geometrical principle all in protection scope of the present invention according to the preferred embodiment of the present embodiment.
Embodiment 2:
As shown in Figures 1 to 3, as different from Example 1, tubular checkout gear in embodiment 2 comprises auxiliary folder 6 and is used for controlling the second servomotor 5 of this auxiliary folder 6 action, namely the auxiliary folder 6 of CNC tube bending machine 1 and the second servomotor 5 is directly utilized as a kind of sensor of measuring distance to detect the snap-off-distance of pipe fitting 8, the output of the second servomotor 5 is connected to the input to the control system that Detection Information processes, the output of control system is simultaneously connected with the input of the second servomotor 5, Detection Information is fed back thus controls the action of auxiliary folder 6 by the second servomotor 5, its principle is: the auxiliary folder 6 of CNC tube bending machine 1 controls it by the second servomotor 5 to move auxiliary pushing away on clamp arm, once auxiliary folder 6 is stressed, the moment of torsion of the second servomotor 5 of its correspondence will increase.
Utilize this principle, the detecting step of embodiment 2 is as follows: first main folder 4 and auxiliary folder 6 still clamping pipe fitting 8, now the position of auxiliary folder 6 is designated as A
1.Then, unclamp auxiliary folder 6, make to retreat to thereafter not come in contact with pipe fitting 8 and just stop afterwards, at this time the moment of torsion of the second servomotor 5 is close to 0, now the moment of torsion of the second servomotor 5 is 0 in theory, but frictional force, impact by factors such as auxiliary folder 6 and the gravity of the second servomotor 5 own in actual operation process, therefore now the moment of torsion of the second servomotor 5 close to 0.Meanwhile, there is resilience in the B section 82 of pipe fitting 8, after pipe fitting 8 resilience completes, second servomotor 5 controls auxiliary folder 6 to Anti-wrinkling board 3 direction feeding, when touching the pipe fitting 8 after resilience, owing to being subject to the resistance of pipe fitting 8, the moment of torsion of the second servomotor 5 increases, and rapidly by the information transmission of change to control system, control system sends feedback information and gives auxiliary folder 6 feed-disabling immediately, and now the position of auxiliary folder 6 is designated as A
2, the position of auxiliary folder is with A
1for home position, contrast position A according to after the rotating signal of the rotation number of turns of calculating second servomotor 5, individual pen stroke and the second servomotor 5
1obtain.Contact the anxious relative distance change stopped under latter two state of pipe fitting 8 with second time when clamping pipe fitting 8 by more auxiliary folder 6 again, namely auxiliary folder is by position A
1move to position A
2distance be A
3, just can draw the snap-off-distance a of pipe fitting 8, a=A
3.The principles such as the calculating of following spring back angle, the calculating of rebound degree are similar to Example 1, do not repeat them here.
