Technical Field

[0001] The invention relates to the technical field of pipe bending, in particular to a special pipe bending auxiliary tool. Background Art

[0002] At the pipeline laying construction site, due to the complexity of the pipeline equipment, large-diameter pipelines usually have design drawings, while small-diameter pipelines, as auxiliary pipelines, need to adjust their direction at any time according to the construction conditions on site, or adjust their direction multiple times to avoid large-diameter pipelines, equipment and other obstacles. Therefore, small-diameter pipelines need to be bent at different angles during installation to adjust the direction of the pipeline.

[0003] For example, when the inlet and outlet pipes of the finned evaporator are bent and formed in sequence according to the design requirements, the last pipe part to be bent is blocked by the completed part, making the pipe bending operation difficult. Moreover, when the bending radius and pipe diameter of the pipe are different, the fixture of the pipe bending tool cannot be disassembled and replaced, which narrows its scope of application.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example:

[0021] See also Figures 1 to 5 , the present invention provides a technical solution:

[0022] A special pipe bending auxiliary tool, such as Figure 1 As shown, it includes a working platform 1, on which a support 2 and a telescopic pile 3 are installed. A threaded groove is opened inside the telescopic pile 3, and the telescopic pile 3 can be lengthened and shortened by a threaded rod. A slide groove 4 runs through the center of the support 2, and a push-pull rod 5 is slidably connected in the slide groove 4. One end of the push-pull rod 5 is detachably connected to a support rod 6 through a snap device, and the end of the support rod 6 away from the push-pull rod 5 is fixedly connected to a first clamp 7.

[0023] like Figure 4 As shown, the snap-fit ​​device includes a wedge block 13, a T-shaped rod 14 and a first spring 15. A sliding groove is provided at one end of the push-pull rod 5 close to the support rod 6. The end of the support rod 6 inserted into the sliding groove is magnetically connected to the magnet 16. The upper and lower sides of the support rod 6 are in contact with the wedge block 13. The end of the wedge block 13 away from the support rod 6 is fixedly connected to the T-shaped rod 14. The end of the T-shaped rod 14 away from the wedge block 13 is slidably connected to the limit rod 17. The first spring 15 is elastically connected between the wedge block 13 and the limit rod 17.

[0024] like Figure 5 As shown, the first clamp 7 and the second clamp 9 with a groove portion 8 on one side are engaged and connected. The centers of the first clamp 7 and the second clamp 9 are each provided with a hole groove 11 for inserting the pipe 10. On the first clamp 7 and the second clamp 9, and on both sides of the hole groove 11, first holes 12 for inserting the telescopic pile 3 are penetrated. The second clamp 9 and the working platform 1 are detachably connected through the limit devices at both ends; as shown Figure 1 and Figure 3As shown, the limiting device includes a limiting block 18, a second spring 19 and a fixed block 20. A second hole 21 is opened in the center of the limiting block 18. The telescopic pile 3 can pass through the first hole 12 and the second hole 21. One end of the second spring 19 is elastically connected to the limiting block 18, and the other end is elastically connected to the fixed block 20. The outer diameter of the telescopic pile 3 is equal to the inner diameter of the first hole 12 and the second hole 21.

[0025] like Figure 3 As shown, a limiting groove 22 for limiting the bending angle of the pipe 10 is fixedly installed on the working platform 1, and a slot 23 is opened on the push-pull rod 5. The slot 23 and the telescopic rod 24 are plugged and connected.

[0026] In this embodiment, through the abutment of the wedge block 13 and the support rod 6, the fixed connection of the T-bar 14 and the wedge block 13, the sliding connection of the T-bar 14 and the limit rod 17, the elastic connection of the wedge block 13 and the first spring 15, and the magnetic connection of the support rod 6 and the magnet 16, the push-pull rod 5 and the support rod 6 can be effectively engaged and connected, and it is also convenient to disassemble the push-pull rod 5 and the support rod 6. Through the perforated connection between the telescopic pile 3 and the first hole 12 and the second hole 21, the limit block 18 and the telescopic pile 3 can be fixedly connected, and then the limit block 18 and the first clamp 7 and the second clamp 9 are fixedly connected. The limit block 18 is elastically connected to the second spring 19. The elastic action of the second spring 19 can more effectively fix the first clamp 7 and the second clamp 9. When the bending radius and the pipe diameter of the pipeline are different, it is convenient to disassemble the first clamp 7 and the second clamp 9 to replace the corresponding clamps. The design of the hole groove 11 can ensure the roundness of the pipeline 10 after forming.

[0027] In this embodiment, the limiting groove 22 can limit the bending angle of the pipe 10 to prevent the bending angle of the pipe 10 from being too small or too large. The height of the limiting groove 22 can be set according to actual needs. Setting the limiting groove 22 can facilitate the staff to bend the pipe 10. When bending the pipe 10, when the pipe 10 and the limiting groove 22 just contact, the bending of the pipe 10 can be stopped. Through the engagement of the first clamp 7 and the second clamp 9, when the pipe 10 is bent, there is a mutual force between the first clamp 7 and the second clamp 9, which can enhance the stability between each other, so that the first clamp 7 and the second clamp 9 are stable when the pipe 10 is bent.

[0028] The working principle of this special pipe bending auxiliary tool is as follows:

[0029] When in use, first align the first hole 12 of the second clamp 9 with the telescopic pile 3, then push the push-pull rod 5 to the left. The movement of the push-pull rod 5 pushes the support rod 6 and the first clamp 7 to move to the left. When the first clamp 7 is completely moved into the second clamp 9, stop pushing the push-pull rod 5, pull the telescopic rod 24 and the slot 23 to engage, so as to fix the first clamp 7, and fix it with the telescopic pile 3 by rotating the threaded rod, and then drive the telescopic pile 3 to move upward, and at the same time pull the limit blocks 18 on both sides of the second clamp 9 to move toward each other, so that the telescopic pile 3 can pass through the first hole 12 and the second hole 21, so that the first clamp 7 and the second clamp 9 are firmly connected, and then the pipe 10 is fixed. Insert one end of the pipe 10 into the hole slot 11, hold the other end of the pipe 10 and apply force to the left. When the pipe 10 and the limit slot 22 just touch, stop bending the pipe 10. When it is necessary to bend other pipe 10 radii and different pipe 10 diameters, the threaded rod drives the telescopic pile 3 to move downward. Under the action of the second spring 19, the limit blocks 18 on both sides move in opposite directions, releasing the restriction on the second clamp 9, thereby replacing the second clamp 9, and then pulling the telescopic rod 24 and the slot 23 to separate, pulling the push-pull rod 5 to the right to separate the first clamp 7 and the second clamp 9, pulling the support rod 6 to the left to separate the push-pull rod 5 and the support rod 6, thereby replacing the first clamp 7.

[0030] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
