[0032] Reference Figures 1 to 9 This utility model discloses a fully automatic small U-shaped tube bending and looping integrated machine, including a machine base 1 and a feeding device (not shown in the figure) and a tube bending device 2 disposed on the machine base 1. The feeding device supplies the tubes to the tube bending device 2. The machine base 1 is also provided with a looping device 3, a conveying device 4 and a circulating feeding mechanism 5. A first workbench 101 and a second workbench 102 lower than the first workbench 101 are provided on the machine base 1. The top surface of the first workbench 101 is inclined relative to the top surface of the second workbench 102. The end of the top surface of the first workbench 101 near the second workbench 102 is higher than the end of the top surface of the first workbench 101 away from the second workbench 102. The tube bending device 2 is disposed on the first workbench 101 and inclined along the top surface of the first workbench, and is used to bend the tubes into U-shaped tubes. The circulating feeding mechanism 5 is disposed on the second workbench 102. The turntable 19 of the circulating feeding mechanism 5 is provided with a clamping unit 16, which is used to clamp and fix the U-shaped tubes. The collar device 3 is mounted on the second worktable 102.

[0033] The pipe bending device 2 bends the pipe into a U-shaped tube 7, which is then conveyed by the conveying device 4 to the clamping unit 6 for clamping and fixing. The clamped and fixed U-shaped tube 7 is then sent to the working position of the collar device 3 via the turntable 19. The collar device 3 can fit metal welding rings onto the tube ends of the U-shaped tube. In the above structure, the feeding device and the pipe bending device 2 are the same as in the previous structure, and therefore will not be described in detail.

[0034] like Figure 1 and 2As shown, the conveying device 4 includes a feeding hopper 8, a feeding trough 9, a discharge hopper 10, a vibrating plate assembly 11, and a pushing assembly. The vibrating plate assembly 11 is disposed on the top surface of the second worktable 102 and located between the turntable 19 and the first worktable 101. The feeding trough 9 is disposed outside the first worktable 101, and its length direction is arranged along the direction from the first worktable 101 to the second worktable 102. The discharge hopper 10 is disposed above the second worktable 102 and located between the vibrating plate assembly 11 and the feeding trough 9, and is used to discharge the U-shaped tube into the vibrating plate assembly 11. The pushing assembly is disposed on the top surface of the second worktable 102 and located between the vibrating plate assembly 11 and the turntable 19. Specifically, the vibratory feeder assembly 11 and the discharge hopper 10 are both arranged close to the first worktable 101; the feeding funnel 8 is located at the end of the first worktable 101 away from the discharge hopper 10, the feeding funnel 8 is inclined, and the end of the feeding funnel 8 away from the feeding trough 9 is higher than the end of the feeding funnel 8 close to the feeding trough 9; the edge of the feeding trough 9 is arranged at an acute angle to the top edge of the first worktable 101 close to the feeding trough 9.

[0035] The feeding trough 9 is equipped with a feeding motor 12 and a belt drive unit. The feeding motor 12 is located at one end of the feeding trough 9 near the vibrating plate assembly 11. The conveyor belt of the belt drive unit is located in the feeding trough 9. The output end of the feeding funnel 8 is located above the feeding trough 9. The end of the feeding trough 9 is provided with a guide groove. The outlet of the guide groove is located above the vibrating plate assembly 11. The vibrating plate assembly 11 can transport the U-shaped tube 7 to the pushing assembly and, through the pushing assembly, send the U-shaped tube 7 to the clamping unit 6 for clamping. Through the above structure, the U-shaped tube 7, bent by the tube bending device 2, falls into the feeding funnel 8 and is fed into the feeding trough 9. The feeding trough 9 has a power system, which includes a feeding motor 12 and a belt drive unit. The conveyor belt of the belt drive unit is located in the feeding trough 9. In this way, the U-shaped tube 7 is transported by the feeding funnel 12. The material is conveyed to the discharge hopper 10, and then discharged into the vibratory plate assembly 11. The vibratory plate assembly 11 conveys the U-shaped tube 7 to the pushing assembly through the vibration groove 18. The U-shaped tube 7 stands upright in the vibration groove 18, with its front and back sides closely attached in a row. The tube feet face down and are supported by the bottom of the groove, while the curved section faces up. The vibration groove 18 is a closed arc-shaped groove. When the U-shaped tube 7 is conveyed to the bottom of the groove, its position changes so that the front or back of the U-shaped tube 7 is attached to the bottom of the pushing hole 17. In the above structure, the vibratory plate assembly 11 is an externally purchased product, and the feeding motor 12 and the belt drive unit are also common transmission structures in this field. Therefore, their specific structures are not described in detail.

[0036] like Figure 4As shown, the pushing assembly includes a pushing drive unit 13, a pushing rod 14, a pushing seat 15, and a guide groove 16 and a pushing hole 17 disposed on the pushing seat 15. The pushing hole 17 communicates with the guide groove 16. The pushing rod 14 is located in the pushing hole 17 and connected to the pushing drive unit 13. The output end of the vibration groove 18 is connected to the guide groove 16. The U-shaped tube 7 slides into the guide groove 16 by gravity. The guide groove 16 is a square groove and a semi-closed groove. The width of the guide groove 16 is approximately the same as the width of the U-shaped tube 7, but the width of the groove opening is smaller than the width of the U-shaped tube 7. Therefore, the U-shaped tube 7 will not come out of the groove or deflect in the groove. The U-shaped tube 7 slides into the pushing hole 17 through the guide groove 16. The tube ends of the U-shaped tube 7 naturally face the rod end of the pushing rod 14. The pushing rod 14 pushes the U-shaped tube 7 into the clamping unit 6 through the drive of the pushing drive unit 13. The pushing drive unit 13 is a cylinder.

[0037] like Figure 3 As shown, the clamping unit 6 includes a clamping drive unit (not shown in the figure), a lifting push block 20 connected to the clamping drive unit, a lower clamping seat 21, a movable seat 22, and a clamping groove 23 located between the lower clamping seat 21 and the movable seat 22. Part of the clamping groove 23 is located on the movable seat 22, and the other part is also located on the movable seat 22. The shape of the clamping groove 23 corresponds to that of the U-shaped tube 7, but its size is slightly smaller, thus enabling clamping. The movable seat 22 has a sliding hole I opposite to it, and a sliding rod 24 is located in the sliding hole I. The end of the sliding rod 24 is fixed to the turntable 19. One end of the connecting rod 20 is fixed to the movable seat 22, and the connecting rod 20 slides in conjunction with the sliding hole II on the turntable 19. Below the turntable 19 is an end plate 27 fixed to the connecting rod 26. A clamping spring 25 is provided on the sliding rod 24, and one end of the clamping spring 25 is connected to the sliding rod... The end caps of 24 abut against each other, and the other end of the clamping spring 25 abuts against the movable seat 22. The lifting push block 20 can lift the end plate 27 under the drive of the clamping drive unit. The working principle of the above structure is as follows: when a U-shaped tube 7 needs to be sent into the clamp, the lifting push block 20 lifts the end plate 27 under the drive of the clamping drive unit, thereby lifting the movable seat 22 through the connecting rod 26. The movable seat 22 will squeeze the clamping spring 25 along the slide rod 24, causing the clamping spring 25 to be compressed. At the same time, the clamping groove 23 is opened. At this time, the push rod 14 pushes the U-shaped tube 7 into the groove of the lower clamping seat 21 through the drive of the push drive unit 13. Then the clamping drive unit drives the lifting push block 20 to retract, thereby the clamping spring 25 pushes the movable seat 22 to reset and clamp the U-shaped tube 7. The above structure is simple and can realize the opening and closing of the clamp.

[0038] Furthermore, an auxiliary positioning groove 29 is provided on the outer edge of the turntable 19. The auxiliary positioning groove 29 is a semi-circular groove. The machine base 1 is provided with a positioning drive unit 30 and a positioning rod 31 driven by the positioning drive unit 30. The end of the positioning rod 31 is provided with a positioning wheel 32 that matches the auxiliary positioning groove 29. The circulating feeding mechanism 5 includes a circulating drive motor, a drive gear connected to the circulating drive motor, and a driven gear set on the rotating shaft of the turntable 19. The rotating shaft is set on the machine base 1 through bearings. The positioning drive unit 30 is a cylinder. Because this application adopts gear transmission, and because there is a gap between the gear teeth, this application designs the positioning wheel 32 to match the auxiliary positioning groove 29 for auxiliary positioning. This not only has a simple structure but also low cost.

[0039] like Figure 6 and 7 As shown, the collar device 3 is used to put metal welding rings on the pins of the U-shaped tube 7. The collar device 3 includes a vibrating feed plate 41, a guide plate 42, a collar seat 43, and a collar drive unit 44 and a collar assembly disposed on the collar seat 43. The vibrating feed plate 41 is disposed on the top surface of the second worktable 102 and is located on the side of the turntable 19 away from the first worktable 101. The vibrating feed plate 41 is an outsourced component, so its specific structure is not described in detail. A guide plate 42 is disposed between the vibrating feed plate 41 and the turntable 19. The guide plate 42 is provided with a guide hole 45 and a collar hole 46 that communicates with the guide hole 45. The wall of the collar hole 46 is provided with a positioning groove 47. The collar assembly is driven by the collar drive unit 44 to pass through the collar hole 46 and drive the collar to be sleeved on the U-shaped tube 7. The vibrating feed plate 41 feeds the welding ring to the guide hole 45 of the guide plate 42 through the vibration groove, and then falls from the guide hole 45 into the positioning groove 47 in the collar hole 46. At this time, the metal welding ring is in an upright state and the ring hole of the metal welding ring basically overlaps with the collar hole 46.

[0040] As a specific structure, the collar assembly includes an inner rod 48 and an outer tube 49. Of course, for ease of manufacturing and assembly, there is also a rod seat 51. The collar drive unit 44 is connected to the rod seat 51, and the outer tube 49 can be fixed to the rod seat 51 with screws. The inner rod 48 is located in the outer tube 49 and slides in cooperation with the outer tube 49. The outer tube 49 is provided with a return spring (not shown in the figure) to reset the inner rod 48. The end of the inner rod 48 is provided with a tapered head. The position where the tapered head connects with the inner rod 48 is provided with a stepped surface 50. The end of the U-shaped tube 7 can abut against the stepped surface 50.

[0041] As shown in the figure, the collar mechanism also includes a vertical plate 33 mounted on the rod base 51. Two sliding shafts 34 are fixedly mounted on the vertical plate 33. The sliding shafts 34 are slidably engaged with the guide plate 42, and pin seat plate 1 35 and pin seat plate 2 36 are fixed on the sliding shafts 34. The pin seat plate 1 35 and pin seat plate 2 36 are located on both sides of the guide plate 42, respectively. The guide hole 45 has a pin hole 1 and a pin hole 2 penetrating the guide plate 42. The pin hole 1 is located above the pin hole 2. The pin seat plate 1 35 has a pin 1 37 that can be inserted into the pin hole 1, and the pin seat plate 2 36 has a pin 2 38 that can be inserted into the pin hole 2. Through the above structure, the metal welding rings can be controlled to fall sequentially into the collar hole 46 along the guide hole 45 one by one. When the inner rod 48 is in its initial position without a collar, pin 38 is not inserted into pin hole 2 and will not obstruct the falling of the metal welded ring. At this time, pin 37 passes through pin hole 1 and enters guide hole 45, inserting into the first metal welded ring at the same height, thus preventing the first metal welded ring and the metal welded rings above it from falling. When the inner rod 48 performs collaring, pin 38 moves towards pin hole 2, while pin 37 gradually withdraws from pin hole 1. Finally, when the inner rod 48 delivers the metal welded ring located in collar hole 46 to the predetermined position of U-tube 7, pin 37 completely withdraws from pin hole 1, while pin 38 completely inserts into pin hole 2, and simultaneously the first metal welded ring... The first metal welding ring falls to the position between pin 37 and pin 38, while the second metal welding ring falls to the same height as pin 37. Pin 38 blocks the first metal welding ring from falling. Then the inner rod 48 retracts to the initial position, and pin 38 completely exits the pin hole 2 and no longer blocks the first metal welding ring. At the same time, pin 37 passes through pin hole 1 and enters the guide hole 45 to insert into the second metal welding ring, thus preventing the second metal welding ring from falling. However, the first metal welding ring can fall into the collar hole 46 along the guide hole 45 to wait for the collar. The above process is repeated to realize the sequential collaring.

[0042] The above structure works as follows: the collar drive unit 44 drives the collar assembly to move, the inner rod 48 passes into the metal welding ring located in the positioning groove 47, and lifts the metal welding ring away from the positioning groove, so that the metal welding ring can pass through the collar hole 46 together. After moving a certain distance, the end of the inner rod 48 is inserted into the tube opening until the step surface 50 abuts against the tube opening. At this time, the outer tube 49 continues to move, and the tube foot will be inserted into the outer tube 49. However, the outer tube 49 will push the metal welding ring to continue to move and fit on the tube foot until the predetermined position. Finally, the collar drive unit 44 drives the collar assembly to retract, and the inner rod 48 will also be reset under the action of the return spring.

[0043] Of course, there is a convex ring between the inner rod 48 and the inner hole of the outer tube 49 to mutually restrict each other and prevent the inner rod 48 from coming out of the outer tube 49 under the action of the return spring; and there is also a threaded plug at the end of the outer tube 49, so that the return spring is sealed in the outer tube 49 and will not come out. The above provides a detailed description of a fully automatic small U-tube bending and ringing integrated machine provided by the embodiment of the present utility model. Specific examples are used in this article to illustrate the principle and implementation of the present utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the present utility model; at the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present utility model. Therefore, the content of this specification should not be construed as a limitation of the present utility model.
