[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a pipe forming special pipe bending machine provided by this utility model; Figure 2 for Figure 1 The diagram shows the installation frame structure. Figure 3 for Figure 2 The diagram shows a side cross-sectional view of the mounting frame. Figure 4 for Figure 3 The enlarged schematic diagram of part A is shown. A special pipe bending machine for pipe forming includes: a machine base 1;

[0029] Two mounting frames 2 are provided on the top of the machine base 1. Two snap-fit ​​strips 3 are provided on the sides of the two mounting frames 2. A sliding plate 31 is fixedly installed on one side of each of the two snap-fit ​​strips 3. The sliding plate 31 is slidably connected to the inside of the side of the mounting frame 2. A connecting plate 32 is fixedly installed at one end of the sliding plate 31. A threaded ring 33 is fixedly installed inside the connecting plate 32.

[0030] A rotating handle 4 is disposed on the top of the mounting frame 2. A rotating shaft 41 is fixedly installed on the bottom of the rotating shaft 4. A worm gear 42 is fixedly installed on the outer side of the rotating shaft 41. A worm wheel 43 is meshed on the side of the worm gear 42. A threaded rod 44 is fixedly installed inside the worm wheel 43. The threaded rod 44 is threadedly connected to the inner side of the threaded ring 33.

[0031] A feeding assembly 11 is fixedly installed at one end of the top of the machine base 1, and a wheel mold assembly 12, a front clamp mounting seat 13 and a rear guide mounting seat 14 are provided at the other end of the top of the machine base 1.

[0032] The two mounting frames 2 are respectively fixedly mounted on the sides of the front clamp mounting base 13 and the rear guide mounting base 14.

[0033] The top of the outer side of the rotating shaft 41 is rotatably connected to the top of the mounting frame 2, and the bottom of the rotating shaft 41 is rotatably connected to the bottom of the inner side of the mounting frame 2.

[0034] The two ends of the threaded rod 44 are respectively rotatably connected to the two sides of the inner side of the mounting frame 2.

[0035] The self-locking characteristic between the worm 42 and the worm wheel 43 can lock the connecting plate 32 during use, thereby increasing the stability of the mold installation.

[0036] When in use, the feeding assembly 11 is used to transport the pipe to be processed to the bending processing position at a set speed and length, ensuring the continuity and accuracy of the bending processing.

[0037] When in use, the wheel mold assembly 12 applies bending force to the pipe by rotating the wheel mold, so that the pipe is bent and shaped according to the set bending radius and angle.

[0038] The front clamping mounting base 13 and the rear guide mounting base 14 provide mounting support for the front clamping mold 6 and the rear guide mold 7, ensuring the positional accuracy of the molds during the pipe bending process and ensuring the quality of the pipe bending process.

[0039] The pipe forming special pipe bending machine provided by this utility model allows for individual setting of the auxiliary push and speed for each layer during use, thereby ensuring quality and improving production efficiency.

[0040] The working principle of the pipe bending machine for pipe forming provided by this utility model is as follows:

[0041] When in use, the mold can be moved downward from the top of the snap-fit ​​strip 31 so that the mold snaps onto the outer side of the snap-fit ​​strip 3. Then, the user rotates the handle 4, which drives the rotating shaft 41 to rotate, thereby causing the rotating shaft 41 to drive the worm 42 to rotate. Then, the worm 42 meshes with the worm wheel 43, thereby driving the threaded rod 44 to form a threaded connection on the inner side of the threaded ring 33. Then, the threaded ring 33 drives the connecting plate 32 and the sliding plate 31 to move away from the mold, thereby driving the snap-fit ​​strip 3 to move and clamp the mold onto the side of the mounting frame 2.

[0042] Compared with related technologies, the pipe bending machine for pipe forming provided by this utility model has the following beneficial effects:

[0043] The installation frame 2, snap-fit ​​strip 3, sliding plate 31, connecting plate 32, threaded ring 33, rotating shaft 41, worm 42, worm wheel 43, and threaded rod 44 work together to create a seamless connection. During use, simply move the mold downwards from the top of the snap-fit ​​strip 31 to engage with its outer surface. Then, rotate the handle 4 to drive the threaded rod 44 to engage with the inner surface of the threaded ring 33. This causes the threaded ring 33 to move the connecting plate 32 and sliding plate 31 away from the mold, moving the snap-fit ​​strip 3 and securing the mold to the side of the installation frame 2. This simplifies the installation and disassembly of the mold, reduces the workload of operators, lowers the skill requirements for operators, shortens equipment downtime, and improves production efficiency.

[0044] Second Embodiment

[0047] The working principle of the pipe bending machine for pipe forming provided by this utility model is as follows:

[0048] When the mold is installed on the side of the mounting frame 2, the bottom of the mold will abut against the top of the bearing plate 5, which can support the bottom of the mold and increase the stability of the mold installation.

[0049] Compared with related technologies, the pipe bending machine for pipe forming provided by this utility model has the following beneficial effects:

[0050] By setting up the support plate 5, the support plate 5 can support the bottom of the mold during use, thereby increasing the stability of the mold installation.
