Description

Technical Field

[0001] This utility model relates to the field of PVC pipe technology, and in particular to a PVC pipe flaring device. Background Technology

[0002] PVC pipe is a type of pipe made of polyvinyl chloride. It is widely used due to its strong corrosion resistance, good low-temperature flexibility, and long service life. In the process of using PVC pipes, it is often necessary to connect multiple sections, usually using a splicing method. This requires the two ends of the pipe to have different radii. Since these pipes are initially formed with a uniform radius, further flaring is required at one end. Existing flaring devices directly use fixed conical blocks to flare the pipe. Because the conical block has a fixed size, it can only flare fixed sizes for fixed types of pipes, which is a significant limitation. Changing the conical block is also complex and cumbersome. Therefore, there is an urgent need for a PVC pipe flaring device that can flare PVC pipes of various diameters and facilitate the switching of conical blocks. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figure 1-3 This utility model provides a PVC pipe flaring device, including a base plate 1, a mounting base 2 fixedly connected to the base plate 1, a support column 3 fixedly connected to the mounting base 2, a limiting block 4 fixedly connected to the support column 3, and a limiting component for limiting the PVC pipe installed in the limiting block 4; a sliding seat 5 slidably connected to the base plate 1, a support block 6 fixedly connected to the sliding seat 5, a turntable 7 rotatably connected in the support block 6, and a plurality of flaring top blocks 8 of different sizes installed on the turntable 7. The limiting component is correspondingly set with one flaring top block 8, and the plurality of flaring top blocks 8 are distributed along the circumference of the turntable 7. A driving component for controlling the sliding of the sliding seat 5 is installed on the base plate 1. The PVC pipe is limited by the limiting component, and then the sliding seat 5 is driven by the driving component to slide, thereby driving the corresponding flaring top block 8 to cooperate with the PVC pipe to flare the PVC pipe. When it is necessary to replace the flaring top block 8, simply rotate the moving column 19 so that the pad 21 no longer limits the designated flaring top block 8, and then rotate the turntable 7 to move the corresponding flaring top block 8 to the position corresponding to the PVC pipe to perform the flaring operation.

[0019] The scheme is further optimized. The limiting component includes a receiving groove 9 opened in the limiting block 4. Two clamping blocks 10 are slidably connected in the receiving groove 9. Two bidirectional threaded rods 11 are rotatably connected in the receiving groove 9. The two ends of the bidirectional threaded rods 11 have opposite threads. The bidirectional threaded rods 11 pass through the two clamping blocks 10 and are threadedly connected to the clamping blocks 10. A PVC pipe is located between the two clamping blocks 10. An arc-shaped groove 12 is opened on the side of the clamping block 10 near the PVC pipe. A transmission box 13 is fixedly connected to the top of the clamping block 10. The top of the bidirectional threaded rods 11 passes through the top wall of the receiving groove 9 and is rotatably connected to the top wall of the transmission box 13. A transmission gear 14 is fixedly connected to the top of the bidirectional threaded rods 11. A drive gear 15 is rotatably connected in the transmission box 13. The drive gear 15 is located between the two drive gears 14 and meshes with the drive gears 14. A control knob 16 is rotatably connected to the top wall of the transmission box 13. The control knob 16 is coaxially fixedly connected to the drive gear 15. The control knob 16 controls the rotation of the drive gear 15, which in turn drives the two transmission gears 14 to rotate, which in turn drives the two bidirectional threaded rods 11 to rotate, thereby causing the two clamping blocks 10 to move in opposite directions to clamp the PVC pipe.

[0020] Further optimization of the scheme: several sliding grooves 17 are provided on the turntable 7, and the flared top block 8 slides in the sliding groove 17. The sliding groove 17 has a through groove for the flared top block 8 to slide on the side near the clamping block 10. A baffle 18 is fixedly connected to the top of the sliding seat 5. The baffle 18 is located on the side of the support block 6 away from the support column 3. A moving column 19 is threadedly connected to the baffle 18. The sliding groove 17, the moving column 19 and the PVC pipe between the two clamping blocks 10 are arranged correspondingly. Magnets 20 are fixedly connected to the baffle 18 and the other sliding grooves 17 respectively. A magnetic block attracted by the magnet 20 is fixedly embedded on the bottom surface of the flared top block 8. A pad 21 is rotatably connected to one end of the moving column 19. The pad 21 abuts against the corresponding flared top block 8. The other end of the moving column 19 passes through the baffle 18 and is fixedly connected to a disc 22. The disc 22 has an internal hexagonal hole. Rotating the disc 22 drives the moving column 19 to rotate, thereby controlling the pad 21 to abut against the corresponding flaring top block 8, facilitating its positioning and ensuring normal flaring operation. The magnetic block and magnet 20 attract the unwanted flaring top block 8 to be located in the sliding groove 17.

[0021] In a further optimized design, an annular groove 23 is formed within the support block 6, located around the turntable 7. A gear ring 24 is fixedly connected to the turntable 7, situated within the annular groove 23. A rotary motor 25 is fixedly connected within the support block 6, and the output shaft of the rotary motor 25 is fixedly connected to a rotary gear 26 that meshes with the gear ring 24. The rotary motor 25 drives the rotary gear 26 to rotate, which in turn drives the turntable 7 to rotate via the gear ring 24, facilitating the switching of different flared top blocks 8.

[0022] A further optimized design includes a drive assembly comprising a vertical plate 27 fixedly connected to a base plate 1, a threaded post 28 rotatably connected between the vertical plate 27 and the mounting base 2, the threaded post 28 penetrating the sliding seat 5 and being threadedly connected to the sliding seat 5, and a drive motor 29 fixedly connected to the base plate 1, the output shaft of the drive motor 29 being fixedly connected to the threaded post 28. The drive motor 29 drives the threaded post 28 to rotate, thereby causing the sliding seat 5 to slide along the base plate 1.

[0023] The design was further optimized by adding a taper to the end of the flared top block 8 near the limiting block 4. This facilitates the movement of the flared top block 8 into the PVC pipe.

[0024] The working process of this utility model is as follows: In use, the PVC pipe is inserted into the limiting hole 4. Then, the control knob 16 is rotated, which drives the drive gear 15 to rotate, thereby driving the two transmission gears 14 to rotate, which in turn drives the two bidirectional threaded rods 11 to rotate, which in turn drives the two clamping blocks 10 to move towards each other, positioning and limiting the pipe. Then, the corresponding flaring top block 8 is rotated to the position corresponding to the pipe. Then, the disc 22 is rotated, which drives the moving column 19 to rotate, thereby causing the pad 21 to abut against the flaring top block 8, limiting the flaring top block 8. Then, the drive motor 29 is started, which drives the threaded column 28 to rotate, thereby causing the sliding seat 5 to slide, thus causing the support block 6 and the flaring top block 8 to move towards the pipe to perform the flaring operation.
