This greatly reduces the labor intensity, improves the production efficiency, and reduces the error caused by manual operation.

[0045] As shown in Figure 5 the first linear moving device 5 includes a first motor 14 mounted in the rack 1, a first lead screw 15 mounted on the end face of the rack 1, and a first sliding rail 16 arranged in parallel with the first lead screw 15; wherein the first lead screw 15 is driven by the first motor 14.

[0046] In the implementation, the first motor 14 and the first lead screw 15 can be connected through a belt drive, a chain drive, a gear drive or a shaft coupling, etc. The rotation of the first motor 14 drives the rotation of the first lead screw 15. Since the clamping device 6 is sleeved on the first lead screw 15 and placed on the slide rail, the clamping device 6 is moved on the slide rail, thereby changing the position of the clamping device 6 and indirectly realizing the machining of the pipe at other positions.

[0047] Referring to Figures 6-8 As shown in the figure, the clamping device 6 comprises a base 17 sleeved on the first lead screw 15, a shell 18 mounted on the base 17, a clamping jaw 19 arranged on the shell 18, a sleeve 20 sleeved on the clamping jaw 19, and a first air cylinder 21 mounted outside the shell 18. The output end of the first air cylinder 21 is connected with the sleeve 20, and the first air cylinder 21 drives the sleeve 20 to move along the clamping jaw 19, so as to make the clamping jaw 19 contract to clamp or release the pipe.

[0048] The clamping device 6 is mainly used to clamp and release the pipe. Specifically, the base 17 is connected with the first lead screw 15 through a lead screw nut, and the base 17 is placed on the first slide rail 16. The shell 18 is arranged on the base 17, and the clamping jaw 19 is mounted on the end of the shell 18 close to the rotary shaping device 10. The clamping jaw 19 is formed by circumferentially distributing a plurality of claws. When the plurality of claws are closed, the pipe is clamped; when the plurality of claws are opened, the pipe is released. Preferably, three claws are selected to form the clamping jaw 19 in the embodiment, and the sleeve 20 is sleeved on the clamping jaw 19 and is driven by the first air cylinder 21.

The second motor 24 and the second screw rod 25 can be connected through belt transmission, chain transmission, gear transmission or shaft coupling direct connection, etc. The rotation of the second motor 24 drives the rotation of the second screw rod 25. Since the third linear moving device 9 is sleeved on the second screw rod 25 and placed on the second sliding rail 26, the third linear moving device 9 moves on the second sliding rail 26, thereby changing the position of the third linear moving device 9.

[0053] Reference Figure 11 As shown, the third linear moving device 9 comprises a base plate 27 sleeved on the second screw rod 25 and connected with the second sliding rail 26, a third motor 28 mounted on the base plate 27, a third screw rod 29 connected with the output end of the third motor 28, and a third sliding rail 30 arranged in parallel with the third screw rod 29.

[0054] The third linear moving device 9 is arranged transversely on the second linear moving device 8. The third linear moving device 9 is used to drive the rotary shaping device 10, the fourth linear moving device 11 and the material supporting device 12 to move in the transverse direction. Specifically, the third motor 28 and the third screw rod 29 can be connected through belt transmission, chain transmission, gear transmission or shaft coupling direct connection, etc. The rotation of the third motor 28 drives the rotation of the third screw rod 29. Since the rotary shaping device 10 is sleeved on the third screw rod 29 and placed on the third sliding rail 30, the rotary shaping device 10 moves on the third sliding rail 30, thereby changing the position of the rotary shaping device 10.

[0055] Reference Figures 12-14As shown, the rotary shaping device 10 comprises a mounting bracket 31 sleeved on the third lead screw 29 and connected with the third sliding rail 30, a second rotary motor 32 arranged on the mounting bracket 31, a second rotary shaft 33 connected with the output end of the second rotary motor 32, a first shaping die head 34 arranged at the upper end position of the second rotary shaft 33, a first mounting shell 35 sleeved on the second rotary shaft 33, a second air cylinder 36 arranged at the lower part of the first mounting shell 35, a first hinge set 37 arranged in the first mounting shell 35 and connected with the telescopic end of the second air cylinder 36, and a second shaping die head 38 connected with the first hinge set 37; wherein the second air cylinder 36 drives the first hinge set 37 to drive the second shaping die head 38, and the second shaping die head 38 moves to the first shaping die head 34 to clamp the pipe to be processed; the second rotary shaft 33 is driven to rotate by the second rotary motor 32 to shape the pipe to be processed.

[0056] The first shaping die head 34 and the second shaping die head 38 are provided with groove positions suitable for the pipe, and when the groove positions on the first shaping die head 34 and the second shaping die head 38 are matched, the contour of the pipe is clamped. The specific movement process is as follows: after the pipe to be processed is sleeved on the inner rod 4, the pipe is placed in the groove position of the first shaping die head 34, the second air cylinder 36 is driven, the second shaping die head 38 is driven by the first hinge set 37, the second shaping die head 38 moves to the first shaping die head 34 to form clamping of the pipe, and then the second rotary motor 32 drives the second rotary shaft 33 to rotate, since the first shaping die head 34 and the second shaping die head 38 are both mounted on the second rotary shaft 33, the pipe clamping and pipe bending operation can be realized.

[0058] The fourth linear movement device 11 is used to drive the material supporting device 12 to move, adjust the position of the material supporting device 12, facilitate the pipe bending operation in another direction, and solve the processing interference problem of the one-way pipe bender.

[0059] Specifically, at the time of commutation, after the second linear moving device 8 drives to move downward, the second rotating motor 32 of the rotating shaping device 10 rotates 180 degrees, driving the first shaping die head 34 and the second shaping die head 38 to switch positions. Further, the fourth motor 40 and the fourth lead screw 41 can be connected through a belt drive, a chain drive, a gear drive or a shaft coupling, and the rotation of the fourth motor 40 drives the rotation of the fourth lead screw 41. Since the material supporting device 12 is sleeved on the fourth lead screw 41 and placed on the fourth sliding rail 42, the material supporting device 12 moves on the fourth sliding rail 42, thereby changing the position of the material supporting device 12 and enabling the pipe to be processed in another direction.

[0060] The material supporting device 12 includes a moving plate 43 sleeved on the fourth lead screw 41 and placed on the fourth sliding rail 42, a fifth sliding rail 44 arranged on the moving plate 43, a third cylinder 45 mounted on the moving plate 43, a base block 46 mounted on the fifth sliding rail 44 and connected with the output end of the third cylinder 45, and a third shaping die head 47 mounted on the base block 46; the left and right ends of the third shaping die head 47 are each provided with a notch for supporting the pipe.

[0061] The design of the material supporting device 12 ensures the stability and safety of the pipe during shaping, avoiding quality problems caused by deformation or damage of the pipe. Specifically, the third cylinder 45 drives the third shaping die head 47 to move along the direction of the fifth sliding rail 44, driving the notches on the third shaping die head 47 to move to the position of the pipe. Since the notches on the third shaping die head 47 are adapted to the pipe, the pipe is prevented from deforming outward at the bending position when the second rotating shaft 33 rotates the pipe. In order to realize bidirectional processing of the pipe, notches capable of supporting the pipe are arranged on both sides of the third shaping die head 47 to ensure that the pipe does not deform during pipe bending.

The material returning device 48 includes a fourth cylinder 49 arranged on the housing 18, a connecting plate 50 arranged on the telescopic end of the fourth cylinder 49, and an outer pipe 51 arranged on the connecting plate 50. The outer pipe 51 is sleeved on the inner rod 4, and the outer pipe 51 is driven by the fourth cylinder 49 to push the pipe sleeved on the inner rod 4 out.

[0063] Further, in order to facilitate the pipe to exit from the inner rod 4, the material returning device 48 is designed. The specific use process is as follows: the fourth cylinder 49 drives the outer pipe 51 to move, i.e. the pipe is sleeved on the inner rod 4, and the outer pipe 51 moves on the inner rod 4 to push the pipe out of the inner rod 4.
