Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe bending, in particular to a plastic pipe bending device. Background Art

[0002] In the production process of plastic pipes, in order to increase the application range and practicality of plastic pipes, related bending equipment is usually used to bend plastic pipes;

[0003] However, when using bending equipment to bend plastic pipes, workers are usually required to manually place the plastic pipes near the bending structure and use manual operation to determine the bending position of the plastic pipe. This method is not only cumbersome in operation, but the manual operation method means that the determination of the bending position needs to rely on the experience and judgment of the workers. Due to the interference of human factors, the determination of the bending position will be biased, making the bending angle or position of the pipe inaccurate, thereby affecting the overall layout and performance of the pipe, causing stress concentration and fatigue fracture problems in the subsequent use of the pipe, thereby affecting the quality and service life of the pipe.

[0004] Therefore, we proposed a plastic pipe bending device to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention provides a plastic pipe bending device, which solves the problems raised in the above-mentioned background technology.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A plastic pipe bending device comprises a bending table, wherein a feeding piece is slidably connected to the left side of the upper end surface of the bending table, a supporting shaft is fixedly connected to the right side of the upper end surface of the bending table, an auxiliary wheel is fixedly connected to the upper end surface of the supporting shaft, a connecting plate is rotatably connected to the outer surface of the supporting shaft, a clamping piece is slidably connected to the upper end surface of the connecting plate, and a limiting disk is provided on the side of the clamping piece away from the feeding piece.

[0008] As a further solution of the utility model: a connecting frame is fixedly connected to the limit plate, a sliding block is fixedly connected to the connecting frame on the side away from the limit plate, a cross plate is sleeved on the outer surface of the sliding block, the cross plate is fixedly connected to the side wall of the clamping member, a groove is provided on the side of the cross plate close to the sliding block, and the sliding block is slidably connected in the groove.

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] like Figure 1-4 As shown, a plastic pipe bending device includes a bending table 1, a feeding piece 2 is slidably connected to the left side of the upper end surface of the bending table 1, a support shaft 3 is fixedly connected to the right side of the upper end surface of the bending table 1, an auxiliary wheel 4 is fixedly connected to the upper end surface of the support shaft 3, a connecting plate 5 is rotatably connected to the outer surface of the support shaft 3, a clamping piece 6 is slidably connected to the upper end surface of the connecting plate 5, and a limiting disk 7 is provided on the side of the clamping piece 6 away from the feeding piece 2.

[0025] In this embodiment, Figure 3 As shown, a connecting frame 8 is fixedly connected to the limit plate 7, and a slider 12 is fixedly connected to the side of the connecting frame 8 away from the limit plate 7. A transverse plate 10 is sleeved on the outer surface of the slider 12, and the transverse plate 10 is fixedly connected to the side wall of the clamping member 6. A groove 11 is provided on the side of the transverse plate 10 close to the slider 12, and the slider 12 is slidably connected in the groove 11. When the slider 12 is driven to slide in the groove 11, the limit plate 7 can be driven to move horizontally synchronously through the set connecting frame 8, so that the limit plate 7 limits different bending parts of the plastic pipe.

[0026] In this embodiment, Figure 3 As shown, a sliding column 13 is slidably connected to the side of the slider 12 away from the cross plate 10, and the sliding column 13 is slidably connected to the connecting frame 8. The end of the sliding column 13 away from the slider 12 is fixedly connected to the handle 9. When the handle 9 is pulled, the sliding column 13 can be driven to slide on the slider 12 and the connecting frame 8.

[0027] In this embodiment, Figure 3As shown, a return spring 14 is fixedly connected to the side of the handle 9 close to the slider 12, and the end of the return spring 14 away from the handle 9 is fixedly connected to the side wall of the connecting frame 8. The return spring 14 is sleeved on the outer surface of the slide column 13. When the handle 9 is pulled to drive the slide column 13 to slide out from the inside of the slider 12, the return spring 14 connected between the handle 9 and the connecting frame 8 will be pulled at the same time. When the handle 9 is released, the rebound force of the return spring 14 can drive the handle 9 to automatically approach the slider 12 and push the slide column 13 to slide into the slider 12 again.

[0028] In this embodiment, Figure 4 As shown, the handle 9 is symmetrically fixedly connected with a positioning column 17 on one side close to the horizontal plate 10, and the upper and lower end surfaces of the horizontal plate 10 are fixedly connected with vertical plates 15. The vertical plates 15 are evenly spaced with positioning holes 16, and the positioning holes 16 are mutually engaged with the positioning columns 17. The handle 9 can be limited and fixed by the mutual engagement of the positioning columns 17 and the positioning holes 16.

[0029] In this embodiment, Figure 4 As shown, scale plates 18 are fixedly connected to the upper end surface of the upper vertical plate 15 at equal intervals, and each scale plate 18 corresponds to a positioning hole 16. The staff can control the moving distance of the positioning column 17 by observing the scale plates 18.

[0030] The effects achieved by this embodiment are as follows: In the prior art, the staff manually places the plastic pipe on the bending device to determine the bending position, which is not only cumbersome in operation, but also the manual operation method means that the determination of the bending position needs to rely on the staff's experience and judgment. Due to the interference of human factors, the determination of the bending position will be deviated, making the bending angle or position of the pipe inaccurate, thereby affecting the overall layout and performance of the pipe, causing the pipe to have stress concentration and fatigue fracture problems during subsequent use, thereby affecting the quality and service life of the pipe. Compared with the prior art, the bending position of the pipe can be accurately positioned, which is different from the manual placement method that relies on autonomous consciousness. The interference of human factors is reduced, and the deviation of the bending position of the plastic pipe is effectively avoided, which makes the bending angle or position of the plastic pipe inaccurate, causing the pipe to have stress concentration and fatigue fracture problems during subsequent use, thereby improving the quality and service life of the pipe;

[0031] Secondly, by setting the positioning column 17 and the positioning hole 16, after the bending position of the plastic pipe is limited, the adjusted limit plate 7 can be further locked, so that the plastic pipe can be placed on the clamp 6 more firmly and supported by the limit plate 7, so that the plastic pipe can be more stable and less likely to be displaced or fall off during the subsequent bending process, so that the plastic pipe can always maintain a tight connection for bending, thereby reducing the occurrence of errors in the bending of the plastic pipe and improving the bending efficiency of the plastic pipe.

[0032] The working process and principle involved in the overall content of the above embodiment are as follows:

[0033] When the staff needs to place the plastic pipe on the bending table 1 for bending, the part of the plastic pipe that needs to be bent is first heated by the existing heating element. After the heating of the plastic pipe is completed, the staff can pull the handle 9 away from the clamping member 6 as needed, drive the sliding column 13 connected to the handle 9 to slide out from the inside of the slider 12, and pull the return spring 14 connected between the handle 9 and the connecting frame 8. In the process of the handle 9 moving away from the slider 12, the handle 9 can drive the positioning column 17 to move horizontally synchronously, so that the positioning column 17 slides out of the positioning hole 16 opened on the vertical plate 15. After the positioning column 17 completely slides out of the positioning hole 16, the staff can pull the handle 9 horizontally, drive the slider 12 to slide horizontally in the groove 11 opened on the side wall of the horizontal plate 10 through the sliding column 13, and drive the limit plate 7 to move synchronously away from the clamping member 6 through the connecting frame 8. In the process of the movement of the limit plate 7, The staff observes the moving distance of the positioning column 17 above. When the positioning column 17 moves to the specified scale plate 18, the staff can release the handle 9. At this time, the handle 9 can be pulled close to the slider 12 through the rebound force of the return spring 14 connected between the handle 9 and the connecting frame 8, and the sliding column 13 can be pushed into the inside of the slider 12. In the process of the handle 9 moving close to the slider 12, the handle 9 can drive the positioning column 17 to move close to the vertical plate 15 synchronously and snap into the positioning hole 16 opened on the vertical plate 15, so as to fix the position of the handle 9. When the handle 9 cannot move, the slider 12, the connecting frame 8 and the limit plate 7 will not move at the same time. At this time, the staff can place the plastic pipe on the clamping member 6, and make one end of the plastic pipe fit on the side wall of the limit plate 7 to limit the bending part of the plastic pipe, so that the staff can accurately bend the plastic pipe.

[0034] When the plastic pipe is placed in the correct position, the staff can push the clamping part 6 to slide on the upper end surface of the connecting plate 5 close to the auxiliary wheel 4, and make the plastic pipe fit the surface of the auxiliary wheel 4. Finally, the connecting plate 5 is driven to rotate on the supporting shaft 3, driving the clamping part 6 to rotate around the auxiliary wheel 4, and at the same time cooperate with the feeding part 2 to push the plastic pipe to move in the direction of the clamping part 6, which can drive the plastic pipe to bend.
