[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying Figures 1-6 , Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model. Embodiment

[0029] A modular stainless steel pipe bending device includes a workbench 1, an inner shell 2 is embedded and inserted at the top of the workbench 1, an inner gear ring 3 is fixedly connected to the inner wall of the inner shell 2, a boss 4 is arranged in the inner cavity of the inner shell 2 below the inner gear ring 3, an insertion post 5 is inserted into the inner shell 2, an outer gear ring 6 adapted to the inner gear ring 3 is fixedly connected to the surface of the insertion post 5, pins 12 are fixedly connected to both sides of the insertion post 5, locking parts 8 adapted to the pins 12 are respectively arranged through both sides of the inner shell 2, an end head assembly 9 located outside the inner shell 2 is fixedly connected to one end of the locking part 8, a limiting plate 10 rotating inside the inner shell 2 is fixedly connected to the surface of the locking part 8, and a torsion spring 11 is sleeved on the surface of the locking part 8, and both ends of the torsion spring 11 are respectively fixedly connected to the inner wall of the inner shell 2 and the limiting plate 10.

[0030] The specific usage process is as follows: When the machine is being repaired, the user rotates the end component 9, and the end component 9 drives the locking part 8 to rotate. When the locking part 8 rotates, it will also twist the torsion spring 11. In this way, after the disassembly work is completed, under the action of the torsion spring 11, the locking part 8 can still reset. When the locking part 8 rotates, it will also drive the limiting plate 10 to rotate inside the inner shell 2 to limit the locking part 8 and ensure the stability of the locking part 8 during operation. It should be noted that in the initial state, the opening on the locking part 8 faces one side. After the user rotates the locking part 8 by 90 degrees, the opening on the locking part 8 will face, and at this time, the user can remove the adapter block 15 upward. During this period, the insertion post 5 will also be taken out upward, and the pin 12 on the insertion post 5 will also move out of the locking part 8. Finally, the disassembly of the adapter block 15 is completed. Among them, the external gear ring 6 will also disengage from the meshing state with the internal gear ring 3. Among them, the external hexagon head 91 and the internal hexagon groove 92 are both hexagonal. In this way, the user can choose an internal hexagon tool, or an external hexagon tool, or insert a rod into the jack 93 to rotate the locking part 8 for operation, providing more assistance and options for the user's work, and also ensuring that the steel pipe will not move with the bending block 17 during the bending process, providing convenience for the user's work. Then the boss 4 can also be taken out from the workbench 1, and the adapter block 15 and the stepping motor 14 are disassembled for repair, so that the user's repair work is not restricted and affected by the space and light and dark environment. The user can complete the repair work more flexibly and quickly, improving the efficiency of the user's repair work and providing convenience for the user's work. Moreover, after the adapter block 15 and the stepping motor 14 are disassembled from the workbench 1, the volume of the machine becomes smaller and the weight is also reduced, thus facilitating the user's transportation and transfer and providing convenience for the user's transfer work. During installation, the user can first rotate the opening on the locking part 8 upward, and then directly align the insertion post 5 with the opening on the inner shell 2 and put it in. During this period, it is also necessary to ensure that the pin 12 is aligned with the opening on the locking part 8 and the pin 12 is snapped into the locking part 8. Then loosen the end component 9. Under the action of the torsion spring 11, the locking part 8 resets, and the opening on the locking part 8 faces one side, which can limit the upward movement of the pin 12, thereby fixing the insertion post 5 inside the inner shell 2 and completing the installation of the insertion post 5 and the adapter block 15. At the same time, the external gear ring 6 will also mesh with the internal gear ring 3. During this period, the bottom of the adapter block 15 will also be lapped on the boss 4, so as to support the adapter block 15 and ensure the stability of the adapter block 15 during operation. If it is considered inconvenient to align the pin 12 with the locking part 8, the pin 12 does not need to be aligned with the locking part 8. The insertion post 5 can be directly put into the inner shell 2, and then the external gear ring 6 meshes with the internal gear ring 3. It should be noted that both the internal gear ring 3 and the external gear ring 6 are made of ductile materials. In this way, the external gear ring 6 can rotate inside the internal gear ring 3 following the insertion post 5. Then the user rotates through the adapter block 15 and drives the insertion post 5 to rotate.Then, the clamping pin 12 located inside the inner shell 2 will also rotate and displace following the insertion column 5 until the clamping pin 12 is snapped into the locking member 8. During this period, the user needs to forcefully rotate the insertion column 5. Therefore, the external gear ring 6 and the internal gear ring 3 are in a meshing state. Without external force intervention, the external gear ring 6 cannot rotate within the internal gear ring 3. Furthermore, the insertion column 5 and the adapter block 15 cannot move randomly, thus ensuring the stability of the adapter block 15 during operation and improving the efficiency of the assembly work of the bending machine, providing convenience for the user's work. When performing bending work, the steel pipe is inserted between the adapter block 15 and the bending block 17 against the inner side of the limiting member 192. In this way, when the bending block 17 bends the steel pipe, the limiting member 192 can limit the steel pipe to ensure the smooth progress of the steel pipe bending process.

[0031] Therefore, the structure design that the bending structure can be quickly disassembled and assembled from the workbench is adopted. During the work of overhauling, transporting, etc. of the bending device, the bending device can be quickly and flexibly disassembled from the workbench for comprehensive overhaul, and it is also convenient for the user to install it on the transport vehicle, greatly reducing the time spent by the user on the disassembly work and improving the efficiency of the user's overhaul and transport work, providing convenience for the user's work.

[0032] The end head assembly 9 includes an external hexagonal head 91 fixedly connected to the locking member 8. An internal hexagonal groove 92 is opened on the outer side of the external hexagonal head 91, and insertion holes 93 are opened at the top and bottom of the inner cavity of the internal hexagonal groove 92.

[0033] Specifically, with the setting of the end head assembly 9, both the external hexagonal head 91 and the internal hexagonal groove 92 are hexagonal. In this way, the user can choose an internal hexagonal tool, or an external hexagonal tool, or insert a rod into the insertion hole 93 to rotate the locking member 8 for work according to the actual situation, providing more assistance and options for the user's work, and also ensuring that the steel pipe will not move following the bending block 17 during the bending process, providing convenience for the user's work.

[0034] An installation groove 13 adapted to the inner shell 2 is opened at the top of the workbench 1, and the inner shell 2 is fixedly installed in the installation groove 13 by bolts.

[0035] Specifically, with the setting of the installation groove 13, the inner shell 2 is snap - fitted in the installation groove 13 during installation. In this way, the upper surface of the inner shell 2 can be flush with the workbench surface of the workbench 1, thus providing convenience for the bending work of the steel pipe.

[0036] An adapter block 15 is fixedly installed at the top of the insertion column 5. A plurality of first card slots 7 are opened on the surface of the adapter block 15. A stepping motor 14 is arranged at the bottom of the workbench 1, and the output shaft of the stepping motor 14 passes through the insertion column 5 and penetrates to the top of the adapter block 15.

[0037] Specifically, for the setting of the adaptation block 15, the adaptation block 15 will also rotate along with the stepping motor 14 during operation. Moreover, the clamping groove 1 on the adaptation block 15 can also allow the steel pipe to be inserted, realizing the limitation of the steel pipe and preventing the steel pipe from moving during the bending operation, ensuring the smooth progress of the steel pipe bending work and providing convenience for the user's work.

[0038] A connecting arm 16 is fixedly installed on the output shaft of the adaptation block 15 and is located above the adaptation block 15. A bending block 17 is rotatably installed at one end of the connecting arm 16 away from the adaptation block 15.

[0039] Specifically, for the setting of the connecting arm 16 and the bending block 17, the connecting arm 16 is installed on the output shaft of the stepping motor 14, and the bending block 17 is installed on the connecting arm 16. When the stepping motor 14 operates, it can drive the connecting arm 16 and the bending block 17 to rotate, thus realizing the bending process of the steel pipe, providing convenience for the user's work, and the moving radius of the bending block 17 is based on the length of the connecting arm 16.

[0040] One side of the top of the workbench 1 is fixedly installed with a guide rail 18. The bottom end of the bending block 17 is slidably installed in the inner cavity of the guide rail 18. One side of the top of the workbench 1 is fixedly installed with a limiting component 19.

[0041] Specifically, for the setting of the guide rail 18, the guide rail 18 is used to guide and limit the bending block 17 during operation. During operation, the end of the bending block 17 will slide inside the guide rail 18, thus ensuring the stability of the bending block 17 during operation and providing convenience for the user's work. It should be noted that the guide rail 18 can also be designed to be embedded inside the workbench 1, so as to ensure the flatness of the workbench 1 surface and the stability during steel pipe processing.

[0042] The limiting component 19 includes a slide rail 191 fixedly connected to the workbench 1. A limiting member 192 is slidably installed on the surface of the slide rail 191. A positioning pin 193 is inserted into the top of the limiting member 192, and the bottom end of the positioning pin 193 is inserted into the slide rail 191.

[0043] Specifically, for the setting of the limiting component 19, the limiting component 19 can be adjusted according to the thickness of the steel pipe, which is convenient for the user to place the steel pipe inside the limiting component 19 and also ensures that the end of the steel pipe can extend into the clamping groove 1, enabling the steel pipe to perform the bending work normally and providing convenience for the user's work. During adjustment, the positioning pin 193 is pulled out, then the limiting member 192 is slid on the slide rail 191 to adjust the position. After completion, the positioning pin 193 is inserted back into the limiting member 192, and the end of the positioning pin 193 is inserted into the slide rail 191, thereby positioning and fixing the limiting member 192 at the current position.
