The drive mechanism includes a gear mounted on one end of the rotating shaft, a limit plate mounted on the base on one side of the gear, a roller mounted inside the limit plate, and a square hole opened on the base below the gear. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems by providing a pipe end bending device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipe end folding device includes a folding platform with two opposing fixed semi-sleeves sliding on the folding platform. The fixed semi-sleeves are connected to a first linear actuator. The two fixed semi-sleeves abut against each other to form a fixed cavity. One end of the fixed cavity is connected to a transport structure, and the other end of the fixed cavity has a folding cylinder that slides on the folding platform. The folding cylinder is connected to a second linear actuator and can extend into the fixed cavity.

[0007] In the above-mentioned pipe end folding device, the fixed half-sleeve has an outer folding area at the end near the folding cylinder, the folding cylinder has an inner folding area at the end away from the fixed half-sleeve, the outer diameter of the folding cylinder at the end near the fixed cavity is smaller than the inner diameter of the fixed cavity, and a folding groove penetrating the folding platform is provided below the outer folding area.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a pipe end bending device, combined with Figure 1-3 As shown, the device includes a folding platform 10, on which two opposing fixed semi-cylindrical sleeves 11 slide. The fixed semi-cylindrical sleeves 11 are connected to a first linear actuator 12. The two fixed semi-cylindrical sleeves 11 abut against each other to form a fixed cavity 13. One end of the fixed cavity 13 is connected to a transport structure 14, and the other end of the fixed cavity 13 has a folding tube 15 that slides on the folding platform 10. The folding tube 15 is connected to a second linear actuator 16 and can extend into the fixed cavity 13.

[0027] In this embodiment, the flared tube is placed on the transport structure 14. Under the operation of the transport structure 14, the tube is moved between the two fixed half-sleeves 11 on the platform 10. Then, under the operation of their respective first linear actuators 12, the two fixed half-sleeves 11 approach each other and abut against each other, placing the tube into the fixed cavity 13. The outer wall of the tube abuts against the inner wall of the fixed cavity 13. Then, under the operation of the second linear actuator 16, the folding cylinder 15 approaches the tube and extends into the tube. Finally, the flared part of the tube is extruded and formed by the folding cylinder 15. The work efficiency is improved by automatic transport, clamping and folding.

[0028] The fixed half-sleeve 11 has an outer folded edge area 17 at the end near the folded edge tube 15, and the folded edge tube 15 has an inner folded edge area 18 at the end away from the fixed half-sleeve 11. The outer diameter of the folded edge tube 15 at the end near the fixed cavity 13 is smaller than the inner diameter of the fixed cavity 13. A folding groove penetrating the folding platform 10 is provided below the outer folded edge area 17.

[0029] In this embodiment, the folding groove is used to place the tube and fix the lower part of the half-tube sleeve 11 and the folding tube 15, so that the lower part of the tube folding edge is not affected. During the folding process, the folding is performed by the shape of the outer folding area 17 and the inner folding area 18. The outer wall of the tube abuts against the outer folding area 17, and the inner wall of the tube abuts against the inner folding area 18. The tube is deformed and formed under the pressure of the outer folding area 17 and the inner folding area 18.

[0030] The end of the fixed half-cylinder sleeve 11 away from the folded edge cylinder 15 is provided with a stop ring 19 extending into the fixed cavity 13.

[0031] In this embodiment, the front end of the folding cylinder 15 abuts against the inner wall of the unflared part of the tube. During the movement of the folding cylinder 15, the friction between it and the tube will push the tube, so that the tube eventually abuts against the stop ring 19, and the flared part of the tube is located exactly in the working area of ​​the folding, and the stop ring 19 plays the role of blocking and positioning.

[0032] The outer surface of the end of the folded tube 15 near the fixed cavity 13 is provided with a rubber edge ring 20, which has the ability to deform.

[0033] In this embodiment, during the movement of the folding cylinder 15, the friction between the rubber edge ring 20 and the tube is increased, so that the tube can smoothly abut against the stop ring 19 and be positioned in the correct working position.

[0034] The thickness of the rubber rim 20 gradually increases from one end near the fixing cavity 13 to the other end.

[0035] In this embodiment, to prevent the rubber edge ring 20 from being worn down by the tube embedded in the rubber edge ring 20 due to the excessive thickness of the front end of the rubber edge ring 20, the friction between the tube and the folding cylinder 15 gradually increases as the folding cylinder 15 moves, further ensuring that the tube can smoothly abut against the stop ring 19 and be positioned in the correct working position.

[0036] The transport structure 14 includes a transport surface 22 disposed on the support 21, a plurality of rotating rollers 23 disposed on the transport surface 22, inclined guide surfaces 24 disposed on both sides of the transport surface 22, and the width of the transport surface 22 gradually narrows from one end away from the fixed cavity 13 to the other end.

[0037] In this embodiment, the tube moves toward the folding platform 10 under the rotation of the rotating roller 23. The guide surface 24 has a guiding function. With the movement of the tube and the blocking and guiding of the guide surface 24, the tube can move smoothly between the fixed half sleeves 11.

[0038] The fixed cavity 13 is provided with a placement surface 25 below it, and the folding platform 10 is provided with a take-out structure 26, which can open or close the placement surface 25.

[0039] In this embodiment, before the folding is completed, the removal structure 26 is in the closed state. The tube moves to the placement surface 25 under the operation of the transport structure 14. Then, the fixed half-sleeves 11 are brought close to each other to wrap the tube and perform the folding work. After the folding work is completed, the tube is placed back on the placement surface 25. Then, the placement surface 25 is opened by the removal structure 26, so that the tube falls from below.

[0040] The extraction structure 26 includes two placement plates 27 that are rotatably connected to the folding platform 10 and placed opposite each other. The two placement plates 27 abut against each other to form a placement surface 25. The placement plates 27 are connected to the switch structure.

[0041] The switch structure includes a third linear actuator 29 located below the folding platform 10. The end of the placement plate 27 away from its rotation center is connected to the output shaft of the third linear actuator 29 by a connecting rod 30. The two ends of the connecting rod 30 are rotatably connected to the output shaft of the third linear actuator 29 and the placement plate 27, respectively.

[0042] In this embodiment, when the placement surface 25 is opened, the output axis of the third linear actuator 29 moves downward, thereby driving the placement plate 27 to rotate downward through the connecting rod 30. The rotation of the two placement plates 27 causes the placement surface 25 to open, allowing the tube to fall downward smoothly.

[0043] The placement surface 25 has a conveyor belt 31 below it.

[0044] In this embodiment, the pipe that falls from the placement surface 25 falls onto the conveyor belt 31 and moves out of the working area under the operation of the conveyor belt 31.

[0045] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0046] Although this article frequently uses terms such as folding platform 10, fixed half-cylinder sleeve 11, first linear actuator 12, fixed cavity 13, transport structure 14, folding cylinder 15, second linear actuator 16, outer folding area 17, inner folding area 18, stop ring 19, rubber edge ring 20, bracket 21, transport surface 22, rotating roller 23, guide surface 24, placement surface 25, removal structure 26, placement plate 27, switch structure, third linear actuator 29, connecting rod 30, and transport conveyor belt 31, these terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
