[0002] During the processing and installation of PE pipes (polyethylene pipes), flaring is a crucial step, which directly affects the quality and sealing performance of pipe connections. Currently, the flaring methods for PE pipes mostly rely on manual operations or simple mechanical tools, and can only process one PE pipe individually, unable to achieve batch or simultaneous processing of multiple PE pipes, which greatly limits the flaring efficiency. Content of the Utility Model
[0003] In order to overcome the above deficiencies, the present utility model provides a PE pipe flaring tool.
[0004] The technical solution adopted by the present utility model is as follows:
[0005] A PE pipe flaring tool includes a fixed seat. Threaded grooves are respectively opened at the left and right ends of the fixed seat. There are two fixed cylinders on the front side of the fixed seat. The rear ends of the two fixed cylinders are respectively located in the threaded grooves, and the rear ends of the two fixed cylinders are threadedly connected to the threaded grooves. Four mounting holes are opened on the outer wall of the front end of the fixed cylinder, and the four mounting holes are evenly symmetrically distributed in the up, down, left, and right directions. A limit cap is threadedly connected to the inner wall of the front end of the fixed cylinder. A push rod is provided inside the fixed cylinder. The rear end of the push rod penetrates through the fixed seat and is slidably mated with the fixed seat. An expansion plate is provided inside the mounting hole. The front and rear ends of the bottom of the expansion plate are respectively fixedly connected with a second connecting frame and a first connecting frame. Fixed blocks one and two are fixedly connected to the outer wall of the push rod. The fixed block two is located in front of the fixed block one. The distance between the fixed block one and the fixed block two is equal to the distance between the first connecting frame and the second connecting frame. Connecting frames three are fixedly connected to the outer wall of the fixed block one in the up, down, left, and right directions. Connecting frames four are fixedly connected to the outer wall of the fixed block two in the up, down, left, and right directions. A first connecting rod is provided between the left connecting frame three and the first connecting frame. The two ends of the first connecting rod are rotatably connected to the connecting frame three and the first connecting frame. A second connecting rod is provided between the right second connecting frame and the fourth connecting frame. The two ends of the second connecting rod are respectively rotatably connected to the second connecting frame and the fourth connecting frame. Slide holes one and two are respectively opened on the side walls of the first connecting rod and the second connecting rod. A first limiting rod and a second limiting rod are fixedly connected to the inner wall of the fixed cylinder. Both the first limiting rod and the second limiting rod are in the shape of a square frame. The first limiting rod passes through the slide hole one of the first connecting rod, and the first limiting rod is slidably mated with the slide hole one. The second limiting rod passes through the slide hole two of the second connecting rod, and the second limiting rod is slidably mated with the slide hole two.

[0008] Advantages of the utility model:
[0009] The utility model drives two push rods simultaneously through a cylinder, realizing the rapid expansion and retraction of the expanding plate, and can carry out the flaring of two PE pipes simultaneously, improving the flaring efficiency. Since the first connecting rod and the second connecting rod form a parallelogram structure with the expanding plate and are restricted by the first limiting rod and the second limiting rod, the stability and accuracy of the expanding plate during the expansion and retraction processes are ensured. The operation is simple, and only the start and stop of the cylinder need to be controlled to complete the flaring operation. Description of the drawings

Specific implementation manner
[0016] As Figures 1-5As shown: A PE pipe flaring tool, including a fixed seat 1. Thread grooves 2 are respectively opened at the left and right ends of the fixed seat 1. There are two fixed cylinders 3 on the front side of the fixed seat 1. The rear ends of the two fixed cylinders 3 are respectively in the thread grooves 2, and the rear ends of the two fixed cylinders 3 are threadedly connected to the thread grooves 2. Four mounting holes 4 are opened on the outer wall of the front end of the fixed cylinder 3, and the four mounting holes 4 are evenly symmetrically distributed up, down, left, and right. A limit cap 5 is threadedly connected to the inner wall of the front end of the fixed cylinder 3. A push rod 6 is provided inside the fixed cylinder 3. The rear end of the push rod 6 penetrates through the fixed seat 1 and is slidably matched with the fixed seat 1. There is an expansion plate 9 inside the mounting hole 4. The front and rear ends of the bottom of the expansion plate 9 are respectively fixedly connected with a second connecting frame 11 and a first connecting frame 10. Fixed blocks one 7 and two 8 are fixedly connected to the outer wall of the push rod 6. The fixed block two 8 is located in front of the fixed block one 7. The distance between the fixed block one 7 and the fixed block two 8 is equal to the distance between the first connecting frame 10 and the second connecting frame 11. Connecting frames three 12 are fixedly connected to the outer wall of the fixed block one 7 up, down, left, and right. Connecting frames four 13 are fixedly connected to the outer wall of the fixed block two 8 up, down, left, and right. There is a first connecting rod 14 between the left connecting frame three 12 and the first connecting frame 10. The two ends of the first connecting rod 14 are rotatably connected to the connecting frame three 12 and the first connecting frame 10. There is a second connecting rod 15 between the right second connecting frame 11 and the connecting frame four 13. The two ends of the second connecting rod 15 are respectively rotatably connected to the second connecting frame 11 and the connecting frame four 13. Slide holes one 16 and two 17 are respectively opened on the side walls of the first connecting rod 14 and the second connecting rod 15. A first limit rod 18 and a second limit rod 19 are fixedly connected to the inner wall of the fixed cylinder 3. Both the first limit rod 18 and the second limit rod 19 are in the shape of a square frame. The first limit rod 18 passes through the slide hole one 16 of the first connecting rod 14, and the first limit rod 18 is slidably matched with the slide hole one 16. The second limit rod 19 passes through the slide hole two 17 of the second connecting rod 15, and the second limit rod 19 is slidably matched with the slide hole two 17.
[0017] Two support rings 20 are slidably sleeved on the outer wall of the push rod 6. The two support rings 20 are respectively fixedly connected to the inner wall of the fixed cylinder 3 and the rear side wall of the limit cap 5.
[0018] A connecting plate 22 is fixedly connected between the rear ends of the two push rods 6. The middle part of the rear side wall of the fixed seat 1 is fixedly connected with a cylinder 21. The output shaft of the cylinder 21 is fixedly connected to the center of the connecting plate 22.
[0019] First, put the PE pipe to be flared on the outside of the fixed cylinder 3, ensure that the pipe orifice of the PE pipe corresponds to the position of the expansion plate 9, start the cylinder 21, the output shaft of the cylinder 21 contracts and drives the connecting plate 22 to move forward. Since the connecting plate 22 is fixedly connected to the rear ends of the two push rods 6, the two push rods 6 will move forward synchronously.
[0020] As the push rod 6 moves forward, since both ends of the first connecting rod 14 and the second connecting rod 15 are rotatably connected to the third connecting frame 12, the first connecting frame 10, the second connecting frame 11, and the fourth connecting frame 13 respectively, and the first connecting rod 14 and the second connecting rod 15 are respectively restricted to slide within the fixed cylinder 3 by the first limiting rod 18 and the second limiting rod 19, the expansion plate 9 will expand outwards under the action of the first connecting rod 14 and the second connecting rod 15.
[0021] When the expansion plate 9 expands outwards to contact the pipe opening of the PE pipe, it will continue to expand outwards, thereby expanding the pipe opening of the PE pipe. When the pipe opening of the PE pipe expands to the required size, the output shaft of the cylinder 21 extends, driving the push rod 6 to move backward, and the expansion plate 9 retracts into the mounting hole 4 under the action of the first connecting rod 14 and the second connecting rod 15, completing the flaring operation. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
