[0031] Example 1

[0032] like Figure 1-5As shown, this utility model provides a clamping device for a pipe bending machine, including a pipe bending machine tool 1. A clamping base 2 is fixedly installed on the top of the pipe bending machine tool 1. A cylinder 3 is fixedly installed on the top of the clamping base 2. A pushing block 4 is fixedly connected to the output end of the cylinder 3. A clamping block 5 is fixedly connected to the other end of the pushing block 4. A bending pressure shaft 7 is movably installed on the left side of the clamping base 2. A rotary motor is fixedly connected to the bottom of the bending pressure shaft 7. A material guiding module 6 is movably installed on the right side of the clamping base 2. A connecting mechanism is provided on the side of the clamping block 5. The connecting mechanism includes an assembly block 511. A clamp 51 is detachably connected to the other side of the assembly block 511. Fixing bolts 512 are threadedly connected to both ends of the surface of the assembly block 511. Threaded holes are opened at both ends of the clamping block 5 and the assembly block 511. A connecting bolt is threaded inside the threaded hole. A connecting bolt 513 is attached, with a nut 514 threaded onto its outer side. A movable clamping block 53 is movably mounted on the top left end of the clamping base 2. A connecting clip block 54 is fixedly mounted on the top of the movable clamping block 53. A snap-fit ​​plate 52 is fixedly mounted on the top of the clamp 51. The side of the snap-fit ​​plate 52 is movably sleeved on the outside of the connecting clip block 54. A pin plate 55 is movably mounted on the top of the snap-fit ​​plate 52. The assembly block 511 is threadedly connected to the clamp 51 using a fixing bolt 512. Its side is embedded in the inner hole of the clamping block 5. The connecting bolt 513 passes through the threaded hole and is locked with the nut 514, realizing convenient assembly and disassembly of the clamping mechanism. The quick assembly and disassembly function makes it easy to replace the clamp 51 of the clamping mechanism, thereby adapting to the clamping requirements of different specifications of pipe fittings and effectively improving the ease of use of the equipment.

[0033] Example 2

[0034] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a connecting shaft 71 is fixedly connected to the top of the bending shaft 7, a connecting frame 72 is fixedly installed on the outside of the connecting shaft 71, a movable block 73 is movably installed inside the connecting frame 72, a threaded screw 74 is movably connected to the left side of the movable block 73, and a limiting shaft 75 is fixedly installed inside the movable block 73. By rotating the threaded screw 74 according to the pipe type, the movable block 73 is driven to slide inside the connecting frame 72, adjusting the distance between the limiting shaft 75 and the bending shaft 7, thereby adapting to the pipe and facilitating the bending shaft 7 to rotate in conjunction with the bottom rotary motor, and performing bending processing under the limitation of the limiting shaft 75.

[0035] Example 3

[0036] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the material guiding module 6 has an opening 61 inside, and a clamping mechanism is provided inside the opening 61. The clamping mechanism includes a clamping plate 62, and a threaded push rod 63 is movably connected to the side of the clamping plate 62. A telescopic column 64 is fixedly connected to one side of the bottom of the material guiding module 6, and the other end of the telescopic column 64 is fixedly installed on the top of the pipe bending machine tool 1. The pipe passes through the opening 61, and the threaded push rod 63 rotates to drive the clamping plate 62 to push and clamp, thereby fixing the pipe. In conjunction with the telescopic column 64, the material guiding module 6 is moved on the top of the pipe bending machine tool 1 to achieve the feeding function.

[0037] The working principle of the clamping device for this pipe bending machine will be explained in detail below.

[0038] like Figure 1-5 As shown, the pipe passes through the pipe opening 61, and the threaded push rod 63 rotates, driving the clamping plate 62 to push and clamp the pipe, thus fixing it in place. Simultaneously, the telescopic column 64 moves, pulling the material guide module 6 to move on top of the pipe bending machine 1, thus feeding the pipe. The clamp 51 and movable clamping block 53 then hold and fix the pipe. Pushed by the material guide module 6, the pipe is driven into one side of the bending shaft 7. Depending on the pipe type, the threaded screw 74 is rotated, causing the movable block 73 to slide inside the connecting frame 72, adjusting the limit shaft 75 and the bending shaft. The spacing between the 7 is designed to accommodate different pipe materials, allowing the bending shaft 7 to rotate in conjunction with the bottom rotary motor. Under the limit of the limiting shaft 75, bending is performed. The assembly block 511 is then connected to the clamp 51 by the fixing bolt 512. The side of the assembly block 511 is embedded in the inner hole of the clamping block 5. The connecting bolt 513 passes through the threaded hole and is locked with the nut 514, enabling convenient assembly and disassembly of the clamping mechanism. The quick assembly and disassembly function allows for easy replacement of the clamp 51, thus adapting to the clamping requirements of different pipe specifications and effectively improving the ease of use of the equipment.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
