[0022] Reference Figure 1 to Figure 7 A tube rolling device for processing corrugated tubes is proposed, which is used for processing plates into tubes, and comprises: a conveying frame 1 is provided with a plurality of conveying rollers 2, and the conveying rollers 2 are used for conveying plates; a forming frame 3 is arranged at one side of the conveying frame 1; a plurality of first forming plates 4 are arranged on the forming frame 3, and the first forming plates 4 have a first forming groove 5; a plurality of second forming plates 6 are arranged on the forming frame 3, and the second forming plates 6 have a second forming groove 7, and the conveying rollers 2, the first forming plates 4 and the second forming plates 6 are arranged in sequence at intervals along the conveying direction of the plates; a plurality of groups of sliding arc plates 8 are provided, and each group of sliding arc plates 8 is slidably arranged in a first forming groove 5, and a forming space 9 is formed between the sliding arc plate 8 and another adjacent sliding arc plate 8 or the first forming plate 4 in the same group, and a plurality of different forming spaces 9 are formed after the sliding arc plate 8 slides, and different forming spaces 9 are used for forming tubes of different diameters.

[0023] In this embodiment, the conveying roller 2 on the conveying frame 1 can continuously and stably convey the plate, ensuring that the plate moves forward smoothly during the processing, greatly improving the production efficiency. The first forming plate 4 and the second forming plate 6 on the forming frame 3 cooperate with each other, and the plate is gradually guided and formed through the first forming groove 5 and the second forming groove 7 respectively, so that the plate can be accurately rolled into the shape of the pipeline. The sliding arc plate 8 is slidably set in the first forming groove 5. After the sliding arc plate 8 slides, the size of the forming space 9 can be flexibly adjusted to meet the forming requirements of pipes of different diameters, thereby enhancing the versatility of the device. The precise forming process reduces the waste caused by inaccurate forming and reduces the production cost. The device is simple to operate and easy to adjust and maintain.

[0024] As a further technical solution, it also includes: there are a plurality of guide frames 10, which are arranged on the first group of sliding arc plates 8 along the material conveying direction, each guide frame 10 is slidably arranged on a sliding arc plate 8, and the guide frame 10 is located on the side of the sliding arc plate 8 close to the conveying roller 2, and the guide frame 10 is used to receive the plate conveyed by the conveying roller 2; there are a plurality of guide rollers 11, which are rotatably arranged on the guide frame 10, and the guide rollers 11 are used to guide the plate.

[0025] In this embodiment, due to the sliding of the sliding arc plate 8, the heights of different forming spaces 9 are not the same. The guide frame 10 is arranged on the sliding arc plate 8 that slides on the first first forming plate 4 along the material conveying direction, and can smoothly receive the plate conveyed by the conveying roller 2 before the plate enters the forming area, ensuring that the plate is in an accurate position when entering the forming process, avoiding problems such as offset, and improving the precision and quality of forming. The several guide rollers 11 that are rotatably arranged on the guide frame 10 can play a good guiding role in the process of plate movement, so that the plate enters the forming space 9 more smoothly, reducing the friction resistance between the plate and the device, and reducing the risk of plate wear. The rotation characteristics of the guide roller 11 make the conveying of the plate more efficient, further improving the production efficiency. The combination of the guide frame 10 and the guide roller 11 enables the tube rolling device to better adapt to the processing requirements of plates of different specifications and materials, and improves the versatility and flexibility of the device. At the key link of the plate entering the forming area, the guide frame 10 and the guide roller 11 work together to provide stable support and guidance for the entire processing process, ensuring the reliability and stability of the device operation.

[0026] As a further technical solution, it also includes: there are a plurality of pressing wheels 12, which are rotatably arranged on the sliding arc plate 8 and the second forming plate 6, and the pressing wheels 12 are used to guide and press the plate.

[0027] In this embodiment, a plurality of pressure wheels 12 rotatably arranged on the sliding arc plate 8 and the second forming plate 6 can accurately guide the plate when the plate enters the forming space 9 and in the subsequent forming process. Ensure that the plate moves along a predetermined path to avoid deviation or dislocation of the plate during the forming process, thereby improving the forming accuracy and quality of the corrugated tube. The guiding effect of the pressure wheel 12 makes the transition between different components of the plate smoother, reduces production interruptions and adjustment time caused by the deviation of the plate, and improves production efficiency. The pressure wheel 12 can press the plate while guiding the plate. This pressing helps the plate to better fit the shape of the forming space 9, ensures that the shape of the pipe is uniform, and at the same time can enhance the stability of the plate, reduce the deformation and rebound of the plate during the forming process, and improve the structural strength and dimensional stability of the corrugated tube.

[0028] As a further technical solution, it also includes: a plurality of limiting plates 13 are arranged on the first forming plate 4 , and the limiting plates 13 are used to prevent the sliding arc plate 8 from separating from the first forming groove 5 .

[0029] In this embodiment, a plurality of limiting plates 13 are arranged on the first forming plate 4, which can effectively prevent the sliding arc plate 8 from detaching from the first forming groove 5. During the operation of the device, it is ensured that the sliding arc plate 8 always moves on the predetermined track, avoiding equipment failure and production interruption caused by the accidental detachment of the sliding arc plate 8. This stable operation state helps to improve the forming quality and production efficiency of the corrugated pipe, and reduce the maintenance cost and time waste caused by equipment failure. The existence of the limiting plate 13 ensures the accurate relative position between the sliding arc plate 8 and the first forming plate 4, thereby ensuring the stability of the forming space 9. This enables the plate to be curled according to the predetermined shape and size during the forming process, thereby improving the forming accuracy of the corrugated pipe. The addition of the limiting plate 13 enhances the overall reliability of the pipe rolling device. It provides a reliable constraint for the movement of the sliding arc plate 8, reducing the potential safety hazards caused by the loss of control of the sliding arc plate 8. When the sliding arc plate 8 needs to be maintained or adjusted, the limiting plate 13 can play a role in positioning and protection. The operator can operate more conveniently without worrying about the sliding arc plate 8 accidentally falling off.

[0030] As a further technical solution, the first forming plate 4 has a through hole 14, the sliding arc plate 8 has a fixing hole 15 and a locking hole 16 connected to the fixing hole 15, and also includes: a telescopic member 17 is arranged on the first forming plate 4, the telescopic member 17 has a first telescopic rod 18, the first telescopic rod 18 has a plurality of matching holes 19, the first telescopic rod 18 passes through the through hole 14 and enters the fixing hole 15; the locking rod 20 is detachably arranged on the sliding arc plate 8, the locking rod 20 passes through the locking hole 16 and the matching hole 19, and the locking hole 16 is used to fix the sliding arc plate 8 and the first telescopic rod 18.

[0031] In this embodiment, the through hole 14 on the first forming plate 4 cooperates with the fixing hole 15 and the locking hole 16 on the sliding arc plate 8, and the setting of the telescopic member 17 makes it possible to flexibly change the position of the sliding arc plate 8 by adjusting the position of the first telescopic rod 18 in the fixing hole 15. In this way, the size of the molding space 9 can be quickly and accurately adjusted according to the requirements of pipes of different diameters, thereby improving the versatility and adaptability of the device. The locking rod 20 passes through the locking hole 16 and the matching hole 19, and can firmly fix the sliding arc plate 8 and the first telescopic rod 18. During the operation of the device, it is ensured that the sliding arc plate 8 will not be displaced due to external force or vibration, thereby ensuring the stability and consistency of the molding space 9. This adjustable structural design eliminates the need for complex mechanical adjustments or mold replacement when changing to produce corrugated pipes of different diameters, greatly saving adjustment time and improving production efficiency. The combination of the telescopic member 17 and the locking rod 20 provides reliable support and fixation for the sliding arc plate 8, thereby enhancing the overall reliability of the device. In the long-term production process, it can withstand greater pressure and friction, thereby ensuring the stable operation of the equipment.

[0032] As a further technical solution, the locking rod 20 passes through the fixing holes 15 on the sliding arc plates 8.

[0033] In this embodiment, the locking rod 20 passes through the fixing holes 15 on the plurality of sliding arc plates 8, and can fix the plurality of sliding arc plates 8 at the same time, ensuring that the sliding arc plates 8 maintain a relatively stable position relationship during operation. This helps to improve the consistency and stability of the molding space 9, thereby ensuring the molding quality of the corrugated tube.

[0034] As a further technical solution, the second forming plates 6 are slidably arranged on the forming frame 3 , and each second forming plate 6 has a plurality of different second forming grooves 7 .

[0035] In this embodiment, the second forming plate 6 is slidably arranged on the forming frame 3. In order to adapt to the processing requirements of different diameters of the first forming plate 4, the position of the second forming plate 6 can be adjusted to better adapt to the processing requirements of plates of different specifications, thereby improving the versatility of the device. Each second forming plate 6 has a number of different second forming grooves 7, which further increases the adaptability of the device and meets diversified production needs. When it is necessary to replace the production of corrugated pipes of different specifications, the sliding second forming plate 6 can quickly adjust the position without complicated disassembly and installation operations, thus saving adjustment time and improving production efficiency. Reasonable sliding structure design can ensure that the second forming plate 6 operates stably during operation without shaking or offsetting. This helps to improve the stability of the entire device and ensure the molding quality of the corrugated pipe.

[0036] As a further technical solution, the pressing wheel 12 on the second forming plate 6 is located on one side above the second forming groove 7 .

[0037] In this embodiment, the first molding plate 4 is mainly used to press the curvature of the lower half of the tube, while the second molding plate 6 is used to press the curvature of the upper half of the tube. Therefore, the pressing wheel 12 located above can not only guide the plate, but also ensure the forming of the upper half. The pressing wheel 12 can apply appropriate pressure to the plate on one side above the second molding groove 7, which helps the plate to better fit the shape of the molding groove.

[0038] As a further technical solution, it also includes: there are a plurality of shaping members 21, which are slidably arranged on the forming frame 3, and the shaping members 21 are connected to or unconnected with the second forming groove 7 after sliding.

[0039] In this embodiment, a plurality of shaping pieces 21 are slidably arranged on the forming frame 3, and can be further accurately shaped after the bellows is formed. This ensures that the shape and size of the bellows are more stable and accurate, and improves product quality. After sliding, the shaping piece 21 can be docked or undocking with the second forming groove 7, and can flexibly adjust the degree and position of shaping according to production requirements to meet the processing requirements of bellows of different specifications. The slidable shaping piece 21 enables the shaping position to be quickly adjusted during the production process without complicated disassembly and installation operations. This saves adjustment time and improves production efficiency.

[0040] As a further technical solution, the invention further includes: a welding frame 22 is lifted and lowered on the forming frame 3, and the welding frame 22 is used for welding the pressed and formed pipes.

[0041] In this embodiment, the welding frame 22 is lifted and arranged on the forming frame 3, so that the pipe rolling device has a welding function, realizing the integrated processing from sheet rolling to pipe welding. The transportation and equipment switching in the intermediate links are reduced, and the production efficiency is improved. The lifting function of the welding frame 22 can be flexibly adjusted according to the position and size of the pipe to ensure that the welding position is accurate. The accuracy and quality of welding are improved, and the occurrence of welding defects is reduced.
