[0002] In the field of precision metal pipe bending, the pipe bending machine, as the core forming equipment, requires the metal pipe to be precisely positioned on the wheel mold reference surface and bent into shape by mechanical force. However, given the multi-dimensional differences in key specifications such as diameter and wall thickness of metal pipes, the traditional processing mode requires the overall replacement of the wheel mold to adapt to different sizes of pipe fittings. This operation mode is not only cumbersome and severely limited in adaptability, but also directly leads to a series of problems such as a sharp decline in operating efficiency, a significant increase in overall production costs, and an imbalance in forming accuracy and stability. At the same time, it significantly increases the operating threshold and the difficulty of process control, seriously restricting the efficient and refined development of the metal pipe fitting processing industry.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a pipe bending machine for processing metal pipes. The pipe bending machine for processing metal pipes includes a main body component 1 and an adjustment component 2, which work together to adjust the wheel mold.

[0025] The main component 1 includes a pipe bending machine 11, on which a wheel mold 12 is provided.

[0026] The wheel mold 12 is divided into two parts, consisting of two halves of the wheel mold 12.

[0027] The pipe bending machine 11 is a mechanical device used to bend metal or plastic pipes into specific angles and shapes. The wheel mold 12 is a key mold component used to determine the bending radius of the pipe on the pipe bending machine 11 and guide the pipe to bend along its curved surface. A clamping mold is also provided on one side of the wheel mold. The clamping mold is used to clamp the pipe on one side of the wheel mold to prevent the pipe from sliding or moving relative to the wheel mold during bending, thus ensuring accurate bending radius and forming quality. When the pipe bending machine 11 is working, the wheel mold 12 is fixed to the main shaft by bolts and rotates with the main shaft. Its curved surface fits against the outer wall of the pipe to determine the bending radius. At the same time, the clamping mold of the pipe bending machine clamps the pipe. The rotation of the wheel mold drives the pipe to bend gradually along its own curved surface to achieve the forming of the preset angle and shape. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand its working principle.

[0028] Adjustment component 2, disposed on wheel mold 12, includes adjustment component 21. Adjustment component 21 includes a rotating rod 211 inserted into the inner wall of wheel mold 12. The inner wall of rotating rod 211 is provided with a fixing groove 211-1. The inner wall of fixing groove 211-1 is provided with a locking plate 212. There are three locking plates 212. Each locking plate 212 is provided with a thread and a screw hole is provided on the inner wall of wheel mold 12.

[0029] A connecting rod 213 is fixed to one end of the locking plate 212. A positioning rod 214 is inserted into the inner wall of the connecting rod 213. A rotating disk 215 is sleeved on the outer side of the positioning rod 214. A sliding groove 215-1 is opened on the inner wall of the rotating disk 215. The sliding groove 215-1 is divided into two ends, one end is inclined and the other end is arc-shaped and coaxial with the rotating disk 215. When the rotating disk 215 rotates, the positioning rod 214 will first move along the inclined end of the sliding groove 215-1 to the outer ring of the rotating disk 215, and make the locking plate 212 engage with the thread inside the wheel mold 12. At this time, the positioning rod 214 will enter the arc-shaped sliding groove 215-1. When the rotating disk 215 continues to rotate, the locking plate 212 will remain in the current position, so that the rotation of the rotating disk 215 will not be obstructed and the locking plate 212 will not move.

[0030] When it is necessary to adjust the wheel mold 12 to better fit the metal tube, the rotating disk 215 is rotated. The rotation of the rotating disk 215 drives the sliding groove 215-1 to press the positioning rod 214 and move it. The movement of the positioning rod 214 drives the connecting rod 213 to move. The movement of the connecting rod 213 will drive the locking plate 212 to move and engage with the fixing groove 211-1. By moving the locking plate 212 to engage with the screw hole on the inner wall of the wheel mold 12, a threaded connection is formed. At this time, the rotating rod 211 forms a threaded rod. By rotating the rotating rod 211, the half of the wheel mold 12 sleeved on the outside of the rotating rod 211 can be moved, thereby adjusting the wheel mold 12.

[0031] Example 2 Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the adjustment component 2 also includes a support 22, which includes a rotating shaft 221 fixed to the top of the rotating disk 215.

[0033] By rotating the rotating shaft 221, the rotating shaft 221 will drive the rotating disk 215 to rotate. As the rotating disk 215 rotates, the sliding groove 215-1 will be displaced by the rotating pressing positioning rod 214. The positioning rod 214 drives the connecting rod 213 to move the three sets of threaded locking plates 212, so that the locking plates 212 are precisely engaged with the screw holes on the inner wall of the wheel mold 12 to form a threaded connection. At this time, the rotating rod 211 forms a threaded rod structure. By rotating the rotating rod 211, the half of the wheel mold 12 sleeved on its outer side can be driven to move axially, so as to achieve precise adjustment of the wheel mold 12.

[0034] Specifically, a fixed disk 222 is sleeved on the outside of the rotating shaft 221, and a torsion spring 223 is sleeved on the outside of the rotating shaft 221. One end of the torsion spring 223 is fixed to one end of the fixed disk 222, and the other end is fixed to the inner wall of the rotating rod 211.

[0035] By rotating the rotating shaft 221, the rotating shaft 221 drives the fixed disk 222 to rotate. The rotation of the fixed disk 222 applies a torsional force to the torsion spring 223. The rotation of the rotating shaft 221 will drive the rotating disk 215 to rotate.

[0036] Specifically, a connecting groove 211-2 is provided on the inner wall of the rotating rod 211, and a plug rod 224 is inserted into the inner wall of the connecting groove 211-2.

[0037] The connecting groove 211-2 is a straight through groove, which only prevents the rotating rod 211 from rotating and will not block the wheel mold 12 from sliding on the outside of the rotating rod 211.

[0038] When the wheel mold 12 needs to be adjusted, the insert rod 224 is separated from the connecting groove 211-2, and then the locking plate 212 is moved to engage with the screw hole on the inner wall of the wheel mold 12. At this time, the rotating rod 211 can be rotated to drive the wheel mold 12 to move. After the adjustment is completed, the insert rod 224 is moved to engage with the connecting groove 211-2, which can prevent the rotating rod 211 from rotating on its own.

[0039] Specifically, a fixing block 225 is fitted on the outer side of the insertion rod 224.

[0040] The other end of the fixing block 225 is fixed to one end of the clamping mold, which is sleeved on the outside of the wheel mold 12. The fixing block 225 is used to support the insertion rod 224.

[0041] Example 3 Reference Figure 3 and Figure 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0042] Specifically, the adjustment component 2 also includes a positioning element 23, which includes a gear 231 fixed to the top of the rotating shaft 221.

[0043] When it is necessary to adjust the position of the extrusion rod 232, the inner wall of the extrusion rod 232 is provided with a groove corresponding to the gear 231. By sleeved the extrusion rod 232 on the outside of the gear 231, the position of the extrusion rod 232 can be adjusted, and then the extrusion rod 232 can be connected to the rotating shaft 221.

[0044] Specifically, a pressing rod 232 is sleeved on the outside of the gear 231.

[0045] An extension rod is provided on the inner wall of the extrusion rod 232, and the extension rod slides on the inner wall of the extrusion rod 232.

[0046] Specifically, a positioning groove 221-1 is provided on the inner wall of the rotating shaft 221, and a positioning shaft 233 is inserted into the inner wall of the positioning groove 221-1.

[0047] When the wheel mold 12 automatically adjusts to the metal tube, the positioning shaft 233 is separated from the positioning groove 221-1. At this time, the metal tube is inserted between the two wheel molds 12. The wheel mold 12 is rotated to drive the extrusion wheel to apply extrusion force to the steel tube. The steel tube will push the top wheel mold 12 upward. At the same time, the extrusion rod 232 is pushed by the reverse thrust of the positioning bar 235 to drive the rotating rod 211 to rotate. The rotating rod 211 drives the rotating disk 215 to rotate. The rotation of the rotating rod 211 applies torsional force to the torsion spring 223. The rotation of the rotating rod 211 can then drive the rotating disk 215 to drive the locking plate 212 to engage with the thread inside the upper wheel mold 12 and lock the position of the upper wheel mold 12. At this time, the distance between the two wheel molds 12 can adapt to the diameter of the steel tube.

[0048] After the steel pipe is removed, the force of the torsion spring 223 will cause the rotating rod 211 to return to its original position, thereby causing the locking plate 212 to return to its original position.

[0049] Specifically, a positioning block 234 is sleeved on the outside of the positioning shaft 233, and one end of the positioning block 234 is fixed to the top of the rotating rod 211.

[0050] The positioning block 234 is used to support the positioning shaft 233, and the positioning shaft 233 will slide within the positioning block 234 when it moves.

[0051] Specifically, a positioning strip 235 is provided on one side of the extrusion rod 232, and one end of the positioning strip 235 is fixed to the pipe bending machine 11.

[0052] During the automatic adjustment process of the wheel mold 12 to adapt to the metal tube, the positioning shaft 233 is first separated from the positioning groove 221-1 of the rotating shaft 221; then the metal tube is inserted between the two wheel molds 12. When the wheel mold 12 rotates, it drives the extrusion wheel to apply extrusion force to the steel tube, and the steel tube will push the top wheel mold 12 upward. At the same time, the extrusion rod 232 is subjected to the reverse thrust of the positioning bar 235, which drives the rotating rod 211 to rotate.

[0053] When in use, the insertion rod 224 is pulled out from the connecting groove 211-2 of the rotating rod 211 to release the rotation restriction on the rotating rod 211; the rotating shaft 221 is rotated, and the rotating shaft 221 will apply a torsional force to the torsion spring 223, and the rotating shaft 221 will drive the rotating disk 215 to rotate synchronously.

[0054] The groove 215-1 of the rotating disk 215 first presses the positioning rod 214 through the inclined section, causing it to move towards the outer ring of the rotating disk. Then, through the connecting rod 213, it pushes three sets of threaded engaging plates 212 to extend from the fixed groove 211-1 until they precisely engage with the threaded holes on the inner wall of the wheel mold 12, forming a threaded connection. At this time, the positioning rod 214 slides into the arc section of the groove 215-1, and the engaging plates 212 remain in a fixed position to avoid obstructing subsequent operations. The rotating rod 211 forms a threaded rod structure due to the threaded connection between the engaging plates 212 and the wheel mold 12. Rotating the rotating rod 211 drives the half of the wheel mold 12 sleeved on its outer side to move axially, realizing precise adjustment of the wheel mold spacing. After adjustment, the insert rod 224 is inserted back into the connecting groove 211-2. The fixing block 225 supports the insert rod 224, restricting the rotating rod 211 from rotating on its own and keeping the wheel mold position stable.

[0055] When adaptive adjustment of the wheel mold 12 is required, the positioning shaft 233 of the positioning component 23 is pulled out, separating it from the positioning groove 221-1 of the rotating shaft 221, thus releasing the fixation of the rotating shaft 221. The metal tube is then inserted between the two wheel molds 12. When the wheel mold 12 rotates, it drives the extrusion wheel to apply extrusion force to the steel tube. Due to its own diameter, the steel tube will push the top wheel mold 12 upward. When the top wheel mold 12 moves upward, the extrusion rod 232 is subjected to the reverse thrust of the positioning strip 235 fixed to the pipe bending machine 11, which drives the rotating rod 211 to rotate. When the rotating rod 211 rotates, it drives the locking plate 212 to engage with the screw hole of the upper wheel mold 12 again through the sliding groove 215-1 of the rotating disk 215, locking its position so that the distance between the two wheel molds adapts to the diameter of the steel tube. During this process, the rotating shaft 221 drives the fixed disk 222 to torsion spring 223 to store the reset force. After the metal tube is removed, the torsion spring 223 releases the torsion force, which drives the rotating rod 211 and the rotating disk 215 to reset. The locking plate 212 retracts into the fixing groove 211-1, and the wheel mold 12 returns to its initial state. It can flexibly adapt to metal tubes of different diameters, and has both precise control and automatic adaptation capabilities. It is easy to operate and has strong stability.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
