The first servo motor 2 rotates to drive the moving block 5 to move through the screw rod 3, thereby driving the pipe fitting to move through the moving plate 6. The first servo motor 2 is stopped after moving the corresponding length, and the length between the two bends can be accurately controlled;

[0027] The upper surface of the moving block 5 is fixedly connected to a moving plate 6 , the upper surface of the moving plate 6 is fixedly connected to a square block 7 , and the inner wall of the square block 7 is mounted with a rotating mounting seat 8 via a bearing.

[0028] Example 2

[0029] like Figure 1-4 As shown, the utility model provides a technical solution: a gear ring 9 is fixedly sleeved on the outer surface of the rotating mounting seat 8, a second servo motor 10 is fixedly mounted on the upper surface of the square block 7, and the output shaft of the second servo motor 10 is fixedly connected to the rotating shaft 11 through a coupling.

[0030] A gear 12 is fixedly sleeved on the outer surface of one end of the rotating shaft 11, and the tooth surface of the gear 12 is meshed with the tooth surface of the gear ring 9. A square tube 13 is fixedly sleeved on the inner wall of the rotating mounting seat 8. The second servo motor 10 drives the gear 12 to rotate through the rotating shaft 11, and the gear 12 drives the rotating mounting seat 8 to rotate through the gear ring 9 meshed with it, thereby driving the pipe fitting to rotate the corresponding angle, thereby realizing precise control of the angle between the two bends.

[0031] The outer surface of the square tube 13 is provided with circular holes 14 , which are arranged in a rectangular array in groups of two. A guide rod 15 is movably sleeved on the inner wall of the circular hole 14 .

[0032] One end of each group of two guide rods 15 is fixedly connected to a connecting block 16, and the lower surface of the connecting block 16 is fixedly connected to symmetrically distributed springs 17. The arrangement of the springs 17 allows the pushing block 22 to no longer squeeze the V-shaped clamping block 18, and the springs 17 can drive the V-shaped clamping block 18 to reset, preparing for the next clamping. One end of the two springs 17 is fixedly connected to the upper surface of the square tube 13.

[0033] The other end of each group of two guide rods 15 is fixedly connected to a V-shaped clamping block 18, and an inclined surface 19 is provided on the upper surface of the V-shaped clamping block 18. An electric telescopic rod 20 is fixedly installed on the inner wall of one side of the square tube 13, and one end of the electric telescopic rod 20 is fixedly connected to a square plate 21. The electric telescopic rod 20 drives the pushing inclined block 22 to move through the square plate. The inclined surface 19 of the pushing inclined block 22 is adapted to the inclined surface 19 of the V-shaped clamping block 18.

[0035] The utility model does not rely on the operator's experience and visual judgment when in use. Through the setting of the first servo motor and the second servo motor, the length and angle between the two bends of the pipe fitting can be accurately controlled, so that no deviation will occur, and the dimensional accuracy of the finished bent pipe is effectively improved.

[0036] The working process of this utility model:

[0037] Step 1: Place the pipe to be bent into the square tube 13 and start the electric telescopic rod 20. The electric telescopic rod 20 drives the pusher block 22 to move through the square plate 21. The inclined surface 19 of the pusher block 22 is adapted to the inclined surface 19 of the V-shaped clamping block 18. The movement of the multiple pusher blocks 22 brings the multiple V-shaped clamping blocks 18 closer to each other, thereby clamping and fixing the pipe.

[0038] Step 2: When the pipe needs to be bent at different lengths, the first servo motor 2 is started. With the cooperation of the movable slot 4, the first servo motor 2 rotates and drives the movable block 5 to move through the screw rod 3, thereby driving the pipe to move through the movable plate 6. After moving the corresponding length, the first servo motor 2 is stopped, so that the length between the two bends can be accurately controlled.

[0039] Step three, when there is an angle difference between the two bends, start the second servo motor 10, drive the gear 12 to rotate through the rotating shaft 11, and the gear 12 drives the rotating mounting base 8 to rotate through the gear ring 9 engaged with it, thereby driving the pipe to rotate the corresponding angle, thereby achieving precise control of the angle between the two bends.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
