Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a flaring device for producing HDPE double-wall corrugated pipes. Background Art

[0002] HDPE double-wall corrugated pipe is a pipe made of high-density polyethylene, with an inner and outer two-layer structure. Usually, the outer layer has a smooth surface and the inner layer has a corrugated structure. The inner layer adopts a corrugated structure, which increases the flexibility and flexural resistance of the pipe, making it more suitable for applications that need to adapt to underground changes. After the existing HDPE double-wall corrugated pipe is produced, in order to ensure the normal implementation of the subsequent processing technology, the opening of the HDPE double-wall corrugated pipe needs to be expanded. When expanding the HDPE double-wall corrugated pipe, the prior art generally uses a fixed-specification expansion mold to operate the HDPE double-wall corrugated pipe, inserts the expansion mold into the opening of the HDPE double-wall corrugated pipe, and then heat-processes the HDPE double-wall corrugated pipe to soften it, and then relies on the extrusion of the expansion mold to complete the opening. However, during the operation of the existing device, it is necessary to frequently replace the mold according to the different opening specifications of the HDPE double-wall corrugated pipe, which leads to a decrease in the expansion efficiency when facing HDPE double-wall corrugated pipes with different opening specifications.

[0003] Therefore, in view of the above problems, a flaring device for producing HDPE double-wall corrugated pipes which can be adapted and adjusted according to the opening specifications is now developed. Utility Model Content

[0007] Furthermore, it also includes a supporting mechanism, which includes a guide rod, a supporting frame and a buffer assembly. The upper right side of the mounting frame is connected to the guide rod, the supporting frame is slidably connected to the guide rod, and the supporting frame is connected to a front-to-back symmetrical buffer assembly.

[0008] Furthermore, the driving assembly includes a driving motor, a motor seat and a screw rod. The top of the mounting frame is connected to the motor seat, the motor seat is connected to the driving motor, and the screw rod is connected to the output shaft of the driving motor.

After the adaptation is completed, the expansion component and the heating ring cooperate to quickly soften the opening of the HDPE double-wall corrugated pipe, thereby improving the expansion efficiency.

[0012] 2.

[0018] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0019] A flaring device for producing HDPE double-wall corrugated pipes, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, a driving component 2, a guide frame 3, an expansion component 4 and a heating mechanism 5. The driving component 2 is connected to the top of the mounting frame 1, and the driving component 2 includes a driving motor, a motor seat and a screw. The top of the mounting frame 1 is connected to the motor seat, and the driving motor is connected to the motor seat. The output shaft of the driving motor is connected to the screw. The upper part of the mounting frame 1 is connected to the guide frame 3, and an expansion component 4 for expanding and expanding the HDPE double-wall corrugated pipe is connected between the guide frame 3 and the driving component 2. The expansion component 4 includes a moving part, a rotating part and an expansion part. A moving part is threadedly connected to the driving component 2, and four rotating parts are rotatably connected to the moving part. The rotating parts are all rotatably connected to the expansion parts, and the expansion parts are all arc-shaped structures. The guide frame 3 is provided with a heating mechanism 5 for heating and softening the HDPE double-wall corrugated pipe.

[0020] like Figure 1 and Figure 3 As shown, the heating mechanism 5 includes a sliding frame 51, a connecting pipe 52 and a heating ring 53. The sliding frame 51 is slidably connected to the guide frame 3, and four connecting pipes 52 are connected to the sliding frame 51. The connecting pipes 52 are connected to the heating rings 53 for heating treatment.

[0021] It should be noted that after the production of the HDPE double-wall corrugated pipe is completed, for the needs of subsequent processing, the operator needs to expand the HDPE double-wall corrugated pipe. First, according to the opening state of the HDPE double-wall corrugated pipe, the angle of the expansion component 4 is adjusted. When adjusting, the rotating part is rotated and adjusted, and then the expansion part is rotated and adjusted so that the right side of the expansion part can enter the HDPE double-wall corrugated pipe. Then, the drive component 2 is started. As the drive component 2 runs, the output shaft of the drive motor in the drive component 2 will rotate rapidly, so that the expansion component 4 slides to the right along the guide frame 3, and at the same time pushes the sliding frame 51 to move to the right, so that the connecting pipe 52 drives the heating ring 53 to move to the opening of the HDPE double-wall corrugated pipe. When the heating ring 53 moves into place, the heating ring 53 is started. 53, so that the heating ring 53 starts to heat the opening of the HDPE double-wall corrugated pipe, so that the opening of the HDPE double-wall corrugated pipe begins to soften. When the opening of the HDPE double-wall corrugated pipe softens, as the expansion component 4 moves, the opening of the HDPE double-wall corrugated pipe will be expanded, thereby completing the expansion operation of the HDPE double-wall corrugated pipe. After the operation is completed, the heating ring 53 is closed, and the opening of the HDPE double-wall corrugated pipe is cooled down, and then the driving component 2 is controlled to slide the expansion component 4 to the left and reset. In summary, the HDPE double-wall corrugated pipe of any opening specification can be adapted by adjusting the expansion component 4. After the adaptation is completed, the opening of the HDPE double-wall corrugated pipe is quickly softened by relying on the cooperation of the expansion component 4 and the heating ring 53, thereby improving the expansion efficiency.

[0022] like Figure 1 and Figure 4 As shown, it also includes a support mechanism 6, which includes a guide rod 61, a support frame 62 and a buffer assembly 63. The guide rod 61 is connected to the upper right side of the mounting frame 1, and a support frame 62 for overall support of the unprocessed end of the HDPE double-wall corrugated pipe is slidably connected to the guide rod 61. The support frame 62 is connected to a buffer assembly 63 that is symmetrical front and back and is used to support and buffer the HDPE double-wall corrugated pipe.

[0023] It should be noted that when the opening of the HDPE double-wall corrugated pipe is processed, the opening of the HDPE double-wall corrugated pipe will soften due to heat, making it difficult to effectively support the HDPE double-wall corrugated pipe as a whole. At this time, the position of the support frame 62 can be adjusted according to the length of the HDPE double-wall corrugated pipe, so that the support frame 62 slides along the guide rod 61, and then relies on the buffer component 63 to contact the unprocessed end of the HDPE double-wall corrugated pipe, thereby completing the overall support effect of the HDPE double-wall corrugated pipe and avoiding deformation caused by bending of the HDPE double-wall corrugated pipe. In summary, the position of the support frame 62 is adjusted by sliding to adapt to HDPE double-wall corrugated pipes of different lengths, thereby supporting the HDPE double-wall corrugated pipe and avoiding overall deformation of the HDPE double-wall corrugated pipe due to softening caused by heat processing at the opening.

[0024] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
