Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and processing technology, and in particular to a spiral corrugated pipe bending and positioning device with adjustable bending angle. Background Technology

[0002] With the rapid development of modern industry, spiral corrugated pipes, thanks to their unique structure and performance advantages, have been widely used in many fields such as building water supply and drainage, automobile manufacturing, mechanical engineering, and aerospace. In building water supply and drainage systems, spiral corrugated pipes, with their good flexibility and corrosion resistance, can effectively cope with complex pipeline laying environments. In the automotive manufacturing field, they can be used in fuel lines, brake lines, etc., to ensure the stability and safety of the pipeline system. In the aerospace field, spiral corrugated pipes are used in critical parts such as aircraft hydraulic systems and fuel systems, undertaking the important tasks of conveying fluids and protecting cables.

[0003] Existing spiral corrugated pipe bending and positioning devices mostly employ fixed bending dies and simple positioning structures. Adjusting the bending angle requires manual replacement of the die or adjustment of the positioning components, a cumbersome and inefficient process that makes it difficult to guarantee the accuracy of angle adjustment. Due to the lack of effective positioning and support structures, the spiral corrugated pipe is prone to displacement and twisting during bending, resulting in substandard dimensional accuracy of the bent pipe and surface defects such as scratches and dents, severely impacting product performance and lifespan. Therefore, we propose a novel adjustable bending angle spiral corrugated pipe bending and positioning device to solve these problems. Utility Model Content

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, through the design of a rotating shaft with a scale and pointer, a sliding baffle, and a positioning pin, enables convenient and precise adjustment of the bending angle.

[0023] Please see Figures 1-5This utility model provides a technical solution: an adjustable bending angle spiral corrugated pipe bending and positioning device, including a bending equipment body 1 with a processing platform 2, a first cylinder 3 fixedly connected to the top of the bending equipment body 1, a forming pressure head 5 connected to the output end of the first cylinder 3, a support frame 6 symmetrically fixedly connected to the processing platform 2, a roller shaft fixedly connected to the inner wall of the support frame 6, a rotating shaft 7 sleeved on the roller shaft, and a stop plate 13 fixedly connected to the side wall of the rotating shaft 7 near the inner wall of the support frame 6, located outside the rotating shaft 7. The support frame 6 of the ring has a groove 12 carved on its side end. A sliding baffle 14 is slidably connected in the groove 12. The sliding baffle 14 is located between two grooves 12 and is located below and abuts against the stop plate 13. A slider 18 is fixedly connected to the side end of the sliding baffle 14 located on the outer wall of the support frame 6. A second slot 16 is carved at the end of the slider 18 away from the sliding baffle 14. A first slot 15 is carved in the middle of the side end of the roller shaft. A positioning pin 17 is inserted into the first slot 15 and the second slot 16.

[0024] A pointer 19 is fixedly connected to one end of the slider 18 near the first slot 15. A scale 11 is engraved at equal intervals on the side end of the rotating shaft 7 with the first slot 15 as the center point, and the pointer 19 corresponds to the scale 11.

[0025] Specifically, the pointer 19 on the slider 18 corresponds to the scale 11 on the side of the rotating shaft 7. When adjusting the bending angle, the operator can intuitively read the rotation angle of the rotating shaft 7, which improves the accuracy and convenience of angle adjustment, avoids errors caused by manual angle estimation, and further ensures the accuracy of the bending angle.

[0026] The output end of the first cylinder 3 is connected to an adapter 4. The bottom end of the adapter 4 is grooved. The top end of the forming head 5 is fixedly connected to a bolt 20, and the bolt 20 and the groove are fixed by a threaded shaft 21.

[0027] Specifically, the adapter 4 and the forming head 5 are fixed by the threaded shaft 21, which facilitates quick disassembly and replacement of different models of forming head 5 to adapt to different bending requirements, such as the processing of spiral corrugated pipes with different diameters and bending shapes, thereby enhancing the versatility and flexibility of the device.

[0028] A cylinder seat 10 is fixedly connected to the side end of the support frame 6 located above the slide 12, and a second cylinder 9 is fixedly connected to the cylinder seat 10.

[0029] Specifically, the cylinder seat 10 and the second cylinder 9 on the side of the support frame 6 provide a power foundation for the subsequent structure, ensuring that all components of the device work together and guaranteeing the stability of the bending process.

[0030] Clamping blocks 8 are symmetrically installed on the inner wall of the support frame 6 located directly above the rotating shaft 7, and the output end of the second cylinder 9 is connected to the clamping blocks 8.

[0031] Specifically, the clamping block 8 connected to the output end of the second cylinder 9 can stably clamp the spiral corrugated pipe during the bending process, preventing the pipe from shifting or twisting under pressure, ensuring the accuracy and quality of the bending process, and avoiding product defects caused by pipe displacement.

[0032] The forming head 5 is available in various designs, and the bottom of the forming head 5 can be either curved or right-angled.

[0033] Specifically, the forming head 5 is designed in various models with different shapes such as arc or right angle at the bottom to meet the needs of different bending shapes. Whether it is a spiral corrugated pipe that needs to be bent in an arc or at a right angle, it can be processed by changing the corresponding forming head 5, thus expanding the application range of the device.

[0034] A connecting plate 22 is symmetrically fixedly connected to the side wall of the rotating shaft 7 away from the stop plate 13. A return spring 23 is fixedly connected to the bottom end of the connecting plate 22, and the bottom end of the return spring 23 is fixedly connected to the support frame 6.

[0035] Specifically, the connecting plate 22 and the return spring 23 on the rotating shaft 7 can provide a restoring force after the bending angle is adjusted, which helps the rotating shaft 7 to return to its stable position. At the same time, it enhances the stability of the rotating shaft 7 structure and ensures the accuracy and reliability of the next angle adjustment and bending operation.

[0036] The specific working principle of this utility model is as follows:

[0037] When using this device to bend spiral corrugated pipes, first place the pipe on the processing platform 2 between the two rotating shafts 7. If the bending angle needs to be adjusted, the operator pulls out the positioning pin 17, so that the sliding baffle 14 is released from the limit of the stop plate 13. Rotate the rotating shaft 7. At this time, the pointer 19 on the slider 18 moves on the scale 11 as the rotating shaft 7 rotates, which makes it convenient for the operator to accurately adjust to the required angle. After the adjustment is completed, insert the positioning pin 17 and fix the sliding baffle 14 through the first slot 15 and the second slot 16, thereby locking the position of the rotating shaft 7 and completing the bending angle positioning.

[0038] Next, the second cylinder 9 is activated, pushing the clamping block 8 to stably clamp the spiral corrugated pipe above the rotating shaft 7, preventing the pipe from shifting or twisting during subsequent bending. Then, the first cylinder 3 is activated, driving the forming pressure head 5 downwards via the adapter joint 4 to bend the pipe. Since the forming pressure head 5 can be quickly changed to different models via the threaded shaft 21 to meet diverse bending shape requirements, after each bending operation, the return spring 23 provides a restoring force to the rotating shaft 7, assisting in its stable return to its original position, facilitating the next angle adjustment and bending operation. This cycle repeats, achieving efficient and precise bending of the spiral corrugated pipe.

[0039] In summary, this invention, through its structure including a rotating shaft with a scale and pointer, a sliding baffle, and a positioning pin, enables convenient and precise adjustment of the bending angle. Operators simply need to remove the positioning pin, slide the sliding baffle, rotate the rotating shaft to the desired angle, and then insert the positioning pin to fix it. This eliminates the need for frequent mold changes, significantly improving angle adjustment efficiency while ensuring high precision, thus meeting diverse production needs. The symmetrically installed clamping blocks on the inner wall of the support frame, in conjunction with the second cylinder, stably clamp the spiral corrugated pipe during bending, preventing pipe displacement and twisting. The stop plate abuts against the sliding baffle, further enhancing the positioning effect and ensuring the pipe's position is fixed during bending. This ensures the dimensional accuracy of the bent pipe meets standards, effectively preventing surface scratches, dents, and other quality problems, thereby improving product quality and service life.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
