[0013] In a second aspect, a control method for a processing device for forming an evaporator copper material is provided, the control method comprising the following steps: The pressure sensor senses and judges the clamping pressure of the pipe surface according to the clamping mechanism, and generates a first pressure information value when the pressure value does not reach the set value, and generates a second pressure information value when the pressure value reaches the set value; The pressure sensor sends the first pressure information value to the controller to control the auxiliary pipe bending mechanism to reach the auxiliary position; The pressure sensor sends the second pressure information value to the controller to control the operation of the feeding mechanism, the rotating mechanism and the second cleaning mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The controller controls the clamping mechanism to clamp the surface of the pipe. During the clamping process, when the pressure sensor senses the first pressure information value when the clamping mechanism clamps the surface of the pipe, the pressure sensor sends the generated first pressure information value to the controller. The controller controls the auxiliary pipe bending mechanism to reach the auxiliary station to achieve auxiliary clamping of the pipe surface, thereby improving the stability of the pipe during the pipe bending process. As the pressure of the clamping mechanism on the pipe surface increases to a set value, a second pressure information value is generated. The pressure sensor sends the generated second pressure information value to the controller, and the controller controls the feeding mechanism to push the feeding cylinder to move to feed the pipe. Operation, and at the same time control the rotating mechanism to drive the bending head to rotate. During the rotation of the rotating table, the surface of the pipe is clamped with the help of the clamping mechanism, so that the pipe passes through the inside of the rotating bending groove, and the pipe bending operation is realized. When the rotating table rotates 180 degrees, an elbow is formed. After an elbow is formed, the clamping mechanism and the auxiliary bending mechanism cancel the clamping and auxiliary clamping of the pipe surface. Subsequently, the feeding mechanism continues to push the feeding barrel to move a specified distance, so that the formed elbow is out of contact with the inner wall of the bending groove in the bending head, so that it is convenient for the controller to continue to operate the rotating mechanism to drive the rotating table to rotate in the opposite direction and reset, waiting for the next elbow bending operation.

[0017] 2. When the push plate moves toward the bending head, it will drive the rectangular plate to move synchronously. When the arc block arranged inside the arc groove contacts the surface of the pipe, the pressure sensor senses the first pressure information value. At this time, the pulling port of the rectangular plate contacts the surface of the second linkage pin. As the connecting frame continues to move in the process of compressing the supporting spring, the synchronously moving rectangular plate drives the second linkage pin downward through the pulling port, thereby driving the U-shaped frame to move downward to compress the gas spring. The downward U-shaped frame pulls the sealing plate downward, and under the connection between the conveying cavity and the first cavity, a negative pressure is formed inside the suction cup. The negative pressure inside the suction cup is conducive to stably adsorbing the pipe to be bent on the inner wall of the first guide groove. Therefore, in the process of the bending head and the connecting frame rotating with the rotating table to perform the bending operation, it is conducive to improving the stability of the pipe clamping, facilitating the smooth bending of the pipe along the bending groove, and avoiding the situation in which the bending quality is affected by the unstable clamping during the bending operation.

[0018] 3. The controller controls the operation of the first air pump, and the first air pump performs exhaust operation into the arc-shaped auxiliary shell. The air pressure inside the arc-shaped auxiliary shell increases, and the air is ejected from multiple air jets. The ejected airflow blows the dust and impurities on the surface of the pipe next to the arc-shaped auxiliary shell. Therefore, when the arc-shaped auxiliary shell pressurizes the surface of the pipe and the pipe bending groove performs pipe bending operation on the pipe, it is avoided that the outer arc-shaped part of the pipe elbow is irregularly scratched or cracked due to dust and impurities attached to the surface of the pipe, which affects the quality of the pipe elbow; the pressure signal value felt by the pressure sensor reaches the set value When the pressure sensor sends the second pressure information value to the controller, after the controller receives the second pressure information value sent by the pressure sensor, the controller controls the second air pump to operate, and the second air pump exhausts air into the second cavity through the air outlet pipe. The air pressure inside the second cavity increases, and the air is ejected from multiple air jet holes. The ejected air flow blows away the dust and impurities on the surface of the pipe during the pipe bending process, so as to avoid irregular scratches or cracks on the inner arc part of the pipe elbow caused by dust and impurities attached to the surface of the pipe when the pipe bending groove bends the pipe, thereby affecting the quality of the pipe elbow.

DETAILED DESCRIPTION

[0030] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0031] Application scenario: When processing evaporators, most of the pipes are bent into snake-shaped pipes through pipe bending equipment through multiple arc bending operations. The existing pipe bending equipment is too simple. One end is fed by a feeding barrel. The pipe bending station uses a simple clamp and a bending wheel to bend the pipe. It is not easy to strengthen the stability of the pipe being clamped during the elbow forming process, thus affecting the forming effect of the elbow. like Figures 1 to 9 The processing equipment for forming evaporator copper material shown in the figure comprises a first workbench 1 and a feeding cylinder 2, wherein the feeding cylinder 2 is arranged above the first workbench 1 through a feeding mechanism, and the feeding cylinder 2 is used for inserting the pipe, and further comprises: A second workbench 3, fixedly connected to the end of the first workbench 1; A rotating table 4 is arranged on the top of the second working table 3 through a rotating mechanism; The pipe bending head 5 is fixedly connected to the top of the rotating platform 4, and the surface of the pipe bending head 5 is sequentially provided with a first guide groove 501, a pipe bending groove 502 and a second guide groove 503 which are interconnected; The clamping mechanism is arranged on the surface of the rotating table 4 and is used to limit and clamp the surface of the pipe; The auxiliary pipe bending mechanism is arranged on the top of the second workbench 3 and is used to assist the pipe bending head 5 in performing the pipe bending operation on the pipe; The pressure sensor 6 is used to sense the pressure information value when the clamping mechanism clamps the pipe surface; The controller 7 controls the operation of the auxiliary pipe bending mechanism, the feeding mechanism, the rotating mechanism and the clamping mechanism according to the pressure information value sensed by the pressure sensor 6 to realize the pipe bending operation.

[0032] When working, one end of the pipe is inserted into the feeding barrel 2, and the surface of the pipe passes through the first guide groove 501. The clamping mechanism is controlled by the controller 7 to clamp the surface of the pipe. During the clamping process, when the pressure sensor 6 senses the first pressure information value when the clamping mechanism clamps the surface of the pipe, the pressure sensor 6 sends the generated first pressure information value to the controller 7. The controller 7 controls the auxiliary bending mechanism to reach the auxiliary station to achieve auxiliary clamping of the surface of the pipe, thereby improving the stability of the pipe during the bending process. As the pressure of the clamping mechanism on the surface of the pipe increases to the set value, a second pressure information value is generated. The pressure sensor 6 sends the generated second pressure information value to the controller 7, and the controller 7 controls the feeding machine The structure pushes the feeding barrel 2 to move to realize the feeding operation on the pipe, and at the same time controls the rotating mechanism to drive the bending head 5 to rotate. During the rotation of the rotating table 4, the surface of the pipe is clamped with the help of the clamping mechanism, so that the pipe passes through the rotating bending groove 502 to realize the bending operation on the pipe. When the rotating table 4 rotates 180 degrees, an elbow is formed. After an elbow is formed, the clamping mechanism and the auxiliary bending mechanism cancel the clamping and auxiliary clamping of the pipe surface. Subsequently, the feeding mechanism continues to push the feeding barrel 2 to move a specified distance, so that the formed elbow is out of contact with the inner wall of the bending groove 502 in the bending head, thereby facilitating the controller 7 to continue to operate the rotating mechanism to drive the rotating table 4 to rotate in the opposite direction and reset, waiting for the next elbow bending operation.

[0033] As an optional embodiment, the rotating mechanism includes: The installation opening is formed through the side wall of the second workbench 3; The third motor 25 is fixedly installed inside the installation opening, and the output shaft of the third motor 25 is used to drive the rotating table 4 to rotate; when working, the third motor 25 is controlled by the controller 7 to operate, and the output shaft of the third motor 25 drives the rotating table 4 to rotate.

[0034] As an embodiment of the present invention, the feeding mechanism includes: The second motor 8 is fixedly mounted on the end of the first workbench 1, the end of the output shaft of the second motor 8 is fixedly connected to a threaded rod, and a threaded sleeve is provided on the surface of the threaded rod; The movable seat 9 is slidably connected to the top of the first workbench 1, and the bottom of the movable seat 9 is fixedly connected to the surface of the threaded sleeve; The first motor 10 is fixedly mounted on the top of the moving seat 9, and the output shaft end of the first motor 10 is fixedly connected to the feeding barrel 2; The three-jaw chuck 11 is fixedly mounted at the mouth of the feeding tube 2; The controller 7 is also used to control the operation of the second motor 8 and the first motor 10; During operation, the controller 7 controls the operation of the second motor 8, and the output shaft of the second motor 8 drives the threaded rod to rotate. The threaded sleeve is threadedly connected to the threaded rod. During the rotation of the threaded rod, the threaded sleeve is driven to move laterally, thereby driving the moving seat 9 to move laterally along the top of the first workbench 1. The movement of the moving seat 9 drives the first motor 10 equipped with the feeding cylinder 2 to move. With the help of the movement of the feeding cylinder 2, the pipe is pushed to the pipe bending station. On the one hand, the purpose of feeding is achieved during pipe bending, thereby facilitating the pipe bending operation. On the other hand, after an elbow is formed, the pipe is fed to facilitate the formed elbow to be separated from the contact with the inner wall of the pipe bending groove 502. The three-jaw chuck 11 is set up, and the three-jaw chuck 11 is conveniently clamped on the surface of the pipe through the electronic control operation. Since the pipe needs to be bent into a serpentine shape, it is necessary to perform multiple arc bending operations to form multiple elbows. After the pipe is bent into an arc shape once, the first motor 10 is started by the controller 7. The output shaft of the first motor 10 drives the feeding barrel 2 equipped with the three-jaw chuck 11 to flip. Under the clamping of the three-jaw chuck 11 on the pipe, the pipe is driven to flip and adjust its position, so that the bent elbow part is flipped to the rear, which is convenient for the equipment to continue the arc bending operation. The whole process does not require manual operation and is more automated.

[0035] As an embodiment of the present invention, the clamping mechanism includes: The mounting shell 12 is fixedly connected to the surface of the rotating table 4; The electric push rod 13 is fixedly mounted on the inner wall of the mounting shell 12, and the end of the telescopic rod of the electric push rod 13 is fixedly connected with a push plate 14; The connecting frame 15 is vertically slidably connected to the side wall of the pushing plate 14. The end of the connecting frame 15 is provided with an arc groove 16, which is used to clamp the surface of the pipe; Two guide rails 17 are provided, symmetrically arranged on the inner wall of the mounting shell 12, and the guide rails 17 are composed of an oblique groove 1701 and a transverse groove 1702 which are interconnected; Two first linkage pins 18 are symmetrically connected to the side walls of the connecting frame 15, and the ends of the two first linkage pins 18 are respectively inserted into the inside of the two guide rails 17; The first mounting groove 19 is formed on the groove wall of the arc groove 16. The inner wall of the first mounting groove 19 is slidably connected with an arc block 20. The pressure sensor 6 is embedded in the arc wall of the arc block 20. A plurality of support springs 21 are provided, one end of each of the support springs 21 is fixedly connected to the inner wall of the first mounting groove 19, and the other end of each of the support springs 21 is fixedly connected to the side wall of the arc block 20; During operation, the controller 7 controls the electric push rod 13 to operate, and the telescopic rod of the electric push rod 13 pushes the push plate 14 to move. In the initial state, the end of the first linkage pin 18 connected to the side wall of the connecting frame 15 is inserted into the oblique groove 1701. Therefore, when the pushing plate 14 drives the connecting frame 15 to move together, under the guidance of the oblique groove 1701, the connecting frame 15 moves obliquely upward. When the first linkage pin 18 moves to the junction of the oblique groove 1701 and the transverse groove 1702, the connecting frame 15 moves obliquely upward to the highest point. Under the continued push of the pushing plate 14, the first linkage pin 18 moves along the transverse groove 1702, thereby driving the connecting frame 15 to move horizontally toward the pipe bending station of the pipe bending head 5. During the horizontal movement of the connecting frame 15, the arc wall of the arc block 20 first touches the surface of the pipe to squeeze and clamp the surface of the pipe, and the pressure sensor 6 will sense the first pressure information value, thereby controlling the operation of the auxiliary pipe bending mechanism through the controller 7. As the push plate 14 continues to move horizontally until it stops, the multiple support springs 21 arranged between the first mounting groove 19 and the arc block 20 are compressed, so that the pressure value of the arc block 20 on the surface of the pipe increases. When the end of the horizontally moving connecting frame 15 contacts the side wall of the bending head 5, the arc block 20 is completely compressed into the inside of the first mounting groove 19. At this time, the arc groove 16 clamps the pipe and limits it inside the first guide groove 501. At the same time, the pressure information value sensed by the pressure sensor 6 increases to the set value, and the rotating mechanism is controlled by the controller 7 to drive the rotating table 4 to rotate.

[0036] As an embodiment of the present invention, the clamping mechanism further includes: A first cavity 22, the first cavity 22 is opened inside the elbow 5; There are multiple second mounting grooves 23, each of which is disposed on the inner wall of the first guide groove 501. A suction cup 24 is fixedly connected to the interior of each second mounting groove 23, and an end of each suction cup 24 is connected to the interior of the first cavity 22 through a connecting pipe; A placement opening is provided on the top of the rotating table 4; The delivery cavity 26 is provided at the bottom of the elbow 5 and is communicated with the interior of the first cavity 22; The sealing plate 27 is disposed inside the conveying cavity 26, and the sealing plate 27 is in sealing contact with the inner wall of the conveying cavity 26; The gas spring 28 is fixedly connected to the inner bottom surface of the placement port, and the piston rod end of the gas spring 28 is fixedly connected to a U-shaped frame 29, and the upper end of the U-shaped frame 29 extends to the inside of the conveying cavity 26 and is fixedly connected to the bottom of the sealing plate 27; The second linkage pin 30 is rotatably connected to the inner wall of the U-shaped frame 29; A first placement groove 31 is provided on the surface of the installation shell 12, and the first placement groove 31 is communicated with the interior of the installation shell 12; A rectangular plate 32 is disposed inside the first placement groove 31, and the rectangular plate 32 is fixedly connected to the bottom of the push plate 14; A pulling opening 33 is provided at the end of the rectangular plate 32 for the second linkage pin 30 to enter; A valve, mounted at the bottom of the sealing plate 27; During operation, the pipe is bent into a serpentine type, which requires multiple arc bending operations. Although the end of the feeding barrel 2 is provided with a three-jaw chuck 11 for clamping and limiting, it is not convenient to improve the stability of the pipe placement near the bending station when clamping, which may seriously affect the quality of the bent pipe. The technical solution can solve the above problems. The specific implementation method is as follows: when the push plate 14 moves toward the bending head 5, it will drive the rectangular plate 32 to move synchronously. When the arc block 20 arranged inside the arc groove 16 contacts the surface of the pipe, the pressure sensor 6 senses the first pressure information value. At this time, the pulling port 33 of the rectangular plate 32 contacts the surface of the second linkage pin 30. As the connecting frame 15 continues to move, the support spring 21 is compressed. During the process, the synchronously moving rectangular plate 32 drives the second linkage pin 30 to move downward through the pulling opening 33, thereby driving the U-shaped frame 29 to move downward to compress the gas spring 28. The downwardly moving U-shaped frame 29 pulls the sealing plate 27 downward, and under the connection between the conveying cavity 26 and the first cavity 22, a negative pressure is formed inside the suction cup 24. The negative pressure inside the suction cup 24 is conducive to stably adsorbing the pipe to be bent on the inner wall of the first guide groove 501. Therefore, in the process of the bending head 5 and the connecting frame 15 rotating with the rotating table 4 to perform the bending operation, it is conducive to improving the stability of the pipe clamping, facilitating the smooth bending of the pipe along the bending groove 502, and avoiding the occurrence of the situation in which the bending quality is affected by the unstable clamping during the bending operation; When the inner wall of the pulling opening 33 is out of contact with the surface of the second linkage pin 30, the gas spring 28 is provided to push the U-shaped frame 29 to move upward and reset, thereby facilitating the placement position of the second linkage pin 30 to remain unchanged and facilitating the next pulling opening 33 to smoothly contact the surface of the second linkage pin 30; During the process of the sealing plate 27 moving up and resetting, the controller 7 controls the valve to open, restores the air pressure balance inside and outside the conveying chamber 26, thereby restoring the air pressure inside and outside the suction cup 24, releasing the suction cup 24 from stable adsorption of the pipe, and facilitating the equipment to continue moving the pipe.

[0037] As an embodiment of the present invention, the auxiliary pipe bending mechanism includes: The outer gear ring 34 is fixedly connected to the surface of the rotating table 4; The rack 35 is slidably connected to the top of the second workbench 3, and the rack 35 and the outer gear ring 34 are meshed with each other; An insert block 36 is fixedly connected to the side wall of the rack 35; A movable frame 37 is slidably connected to the top of the second workbench 3, and an electric cylinder 39 is fixedly installed on the top of the movable frame 37; The mounting plate 38 is fixedly connected to the piston rod end of the electric cylinder 39. The side wall of the mounting plate 38 is provided with an insertion groove 3801, and the insertion groove 3801 is used for inserting the insertion block 36; An arc-shaped auxiliary shell 40 is fixedly connected to the end of the mounting plate 38; The first cleaning mechanism cleans the surface of the pipe that needs to be bent; The controller 7 is also used to control the operation of the electric cylinder 39 and the first cleaning mechanism; During operation, the controller 7 controls the operation of the first cleaning mechanism while controlling the operation of the electric cylinder 39. Therefore, before the arc surface of the arc auxiliary shell 40 is squeezed with the surface of the pipe, the first cleaning mechanism will clean the part of the pipe that is about to contact with the arc auxiliary shell 40 to reduce the adhesion of dust and impurities, avoid extrusion shaking caused by the presence of impurities, thereby affecting the quality of elbow forming, and avoid impurities on the surface of the pipe causing scratches on the surface of the pipe when the arc auxiliary shell 40 is squeezed with the pipe, thereby affecting the quality of elbow forming of this part of the pipe. When the pressure sensor 6 senses the first pressure information value, the controller 7 controls the operation of the electric cylinder 39 to use the piston of the electric cylinder 39 The rod pushes the mounting plate 38 to move to one side of the rack 35 and stops, so that the insertion block 36 on the side wall of the rack 35 is inserted into the inside of the mounting plate 38. When the rotating table 4 rotates, it will synchronously drive the outer gear ring 34 to rotate. Since the outer gear ring 34 and the rack 35 are meshed with each other, the rotation of the outer gear ring 34 prompts the rack 35 to move along the top of the second workbench 3. The moving rack 35 synchronously drives the mounting plate 38 connected with the arc-shaped auxiliary shell 40 to move with the help of the insertion block 36. During the movement, the arc-shaped auxiliary shell 40 will always pass through the surface of the rotating bending head 5. The moving arc-shaped auxiliary shell 40 cooperates with the rotating bending groove 502 to realize the bending operation of the pipe. As an embodiment of the present invention, the first cleaning mechanism includes: A plurality of air jets 41 are provided, and the plurality of air jets 41 are all provided through the arc-shaped wall of the arc-shaped auxiliary shell 40; A first air pump 42 is fixedly mounted on the side wall of the mounting plate 38, and an air outlet pipe of the first air pump 42 is fixedly connected to the arc-shaped auxiliary shell 40; During operation, the controller 7 controls the operation of the first air pump 42, and the first air pump 42 performs exhaust operation into the arc-shaped auxiliary shell 40. The air pressure inside the arc-shaped auxiliary shell 40 increases, and is ejected from multiple air jets 41. The ejected airflow blows the dust and impurities on the surface of the pipe next to the arc-shaped auxiliary shell 40. Therefore, when the arc-shaped auxiliary shell 40 pressurizes the surface of the pipe and the auxiliary bending groove 502 performs a pipe bending operation on the pipe, extrusion and shaking caused by the presence of impurities are avoided, thereby affecting the quality of the elbow forming. At the same time, irregular scratches or cracks on the outer arc-shaped part of the pipe elbow caused by dust and impurities attached to the surface of the pipe are avoided, affecting the quality of the pipe elbow.

[0038] As an embodiment of the present invention, a second cleaning mechanism is provided on the surface of the elbow 5, and the second cleaning mechanism includes: The second cavity 43 is provided inside the elbow 5; There are multiple jet holes 44, each of which is formed on the inner wall of the elbow groove 502, and each of which is connected to the inside of the second cavity 43; The second placement groove 45 is provided on the surface of the elbow 5; A second air pump 46 is fixedly installed inside the second placement groove 45, and an air outlet pipe of the second air pump 46 is fixedly connected to the inside of the second cavity 43; A one-way valve is installed on the inner top surface of the second placement groove 45 and communicated with the interior of the second cavity 43; The controller 7 is also used to control the operation of the second air pump 46; During operation, when the pressure signal value sensed by the pressure sensor 6 reaches the set value, the pressure sensor 6 sends the second pressure information value to the controller 7. After the controller 7 receives the second pressure information value sent by the pressure sensor 6, the controller 7 controls the second air pump 46 to operate, and the second air pump 46 exhausts air into the second cavity 43 through the air outlet pipe. The air pressure inside the second cavity 43 increases, and the air is ejected from multiple air jet holes 44. The ejected air flow blows away the dust and impurities on the surface of the pipe during the pipe bending process, avoiding extrusion and shaking caused by the presence of impurities, thereby affecting the quality of the elbow forming, and at the same time avoiding the inner arc part of the pipe elbow to be irregularly scratched or cracked due to the dust and impurities attached to the surface of the pipe when the pipe bending groove 502 is in close contact with the pipe for the pipe bending operation, thereby affecting the quality of the pipe elbow; After the elbow groove 502 of the elbow head 5 performs the elbow operation on the pipe, if the air pressure inside the second cavity 43 increases, the one-way valve is provided to facilitate the discharge of the air flow inside the second cavity 43 to avoid the situation where the continuous increase in air pressure causes damage to the elbow surface after the bending.

[0039] like Fig.10A control method for a processing device for forming an evaporator copper material is shown, and the control method comprises the following steps: The pressure sensor 6 senses and judges the clamping pressure of the pipe surface according to the clamping mechanism. When the pressure value does not reach the set value, a first pressure information value is generated. When the pressure value reaches the set value, a second pressure information value is generated. The pressure sensor 6 sends the first pressure information value to the controller 7 to control the auxiliary pipe bending mechanism to reach the auxiliary position; The pressure sensor 6 sends the second pressure information value to the controller 7 to control the operation of the feeding mechanism, the rotating mechanism and the second cleaning mechanism.

[0040] As an embodiment of the present invention, the control method of the controller 7 includes the following steps: The controller 7 generates first control information after receiving the first pressure information value; The controller 7 sends the first control information to the electric cylinder 39, and controls the electric cylinder 39 to operate and push the arc-shaped auxiliary shell 40 to move to achieve auxiliary clamping of the pipe surface.

[0041] As an embodiment of the present invention, the control method of the controller 7 further includes: The controller 7 generates second control information and third control information after receiving the second pressure information value; The controller 7 sends the second control information to the second motor 8, controls the second motor 8 to drive the moving seat 9 to move with the help of the threaded rod, and pushes the pipe to move to the pipe bending station to realize the feeding operation; The controller 7 sends the third control information to the rotating mechanism and the second air pump 46 to control the rotating mechanism and the second air pump 46 to operate, so as to achieve the blowing and cleaning operation on the surface of the pipe while bending the pipe.

[0042] The working principle of the present invention is as follows: one end of the pipe is inserted into the inside of the feeding barrel 2, and the surface of the pipe passes through the first guide groove 501. The clamping mechanism is controlled by the controller 7 to clamp the surface of the pipe. During the clamping process, when the pressure sensor 6 senses the first pressure information value when the clamping mechanism clamps the surface of the pipe, the pressure sensor 6 sends the generated first pressure information value to the controller 7. The controller 7 controls the auxiliary bending mechanism to reach the auxiliary station to achieve auxiliary clamping of the surface of the pipe, thereby improving the stability of the pipe during the bending process. As the pressure of the clamping mechanism on the surface of the pipe increases to a set value, a second pressure information value is generated. The pressure sensor 6 sends the generated second pressure information value to the controller 7. The controller 7 controls the feeding barrel 2. The feeding mechanism pushes the feeding barrel 2 to move to realize the feeding operation on the pipe, and at the same time controls the rotating mechanism to drive the bending head 5 to rotate. During the rotation of the rotating table 4, the surface of the pipe is clamped with the help of the clamping mechanism, so that the pipe passes through the rotating bending groove 502 to realize the bending operation on the pipe. When the rotating table 4 rotates 180 degrees, an elbow is formed. After an elbow is formed, the clamping mechanism and the auxiliary bending mechanism cancel the clamping and auxiliary clamping of the pipe surface. Subsequently, the feeding mechanism continues to push the feeding barrel 2 to move a specified distance, so that the formed elbow is out of contact with the inner wall of the bending groove 502 in the bending head, thereby facilitating the controller 7 to continue to operate the rotating mechanism to drive the rotating table 4 to rotate in the opposite direction and reset, waiting for the next elbow bending operation.
