Description

Technical Field

[0001] This utility model relates to the field of air conditioning pipe processing technology, specifically an industrial air conditioning pipe bending machine. Background Technology

[0002] Currently, in the air conditioning manufacturing process, evaporators are used to effectively exchange heat with the outside air to achieve a cooling effect. In order to improve the heat dissipation performance of the evaporator, the copper tubes of the evaporator need to be bent. The bent copper tubes increase the heat dissipation area and effectively improve the heat exchange efficiency.

[0003] An investigation revealed that a Chinese utility model patent discloses an air conditioning refrigeration pipe bending device (publication number: CN213530551U), comprising a frame, a protective shell, a support column, a controller, and a housing. The protective shell is located on both sides and the top of the rear side of the frame. A feed inlet is provided on the left side of the protective shell. A sensor is provided on the front end of the protective shell near the frame. The support column is located at the bottom of the frame. The controller is located on the front side of the frame. The housing is located at the top of the rear side of the frame. The housing includes a rotating mechanism, a rotating column, a first electric rail, and a bending column.

[0004] In the aforementioned patent, the tube opening on the protective shell facilitates the insertion of materials by workers, and the pressure block facilitates the fixation of materials by workers. Workers can change pressure blocks with different hole sizes according to different materials to save time. Inserting materials through the through holes on the pressure block prevents damage or other adverse phenomena when bending the materials. Sensors prevent workers from accidentally touching the device during operation and causing injury. However, when bending the smooth surface of the pipe, due to the lack of effective friction between the pipe and the bending column, axial sliding is prone to occur during the bending process. This sliding will lead to deviation of the bending angle, decrease in forming accuracy, and in severe cases, may cause local thinning or wrinkling of the pipe wall, affecting the product's performance and safety.

[0005] Therefore, this utility model provides an industrial air conditioning pipe bending machine to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides an industrial air conditioning pipe bending machine, such as... Figure 1 , Figure 2 and Figure 4 As shown, the pipe bending machine includes a base plate 1, a support frame 2 fixedly mounted on the base plate 1, a bending table 3 fixedly mounted on the support frame 2, bending wheels 4 and bending frames 5 disposed on the bending table 3, a movable slide rail 6 fixedly mounted on the support frame 2, a first threaded rod 7 rotatably mounted inside the movable slide rail 6, a first motor 8 fixedly mounted on one side of the movable slide rail 6, a clamping plate 9 slidably mounted inside the movable slide rail 6, and a clamping mechanism disposed inside the clamping plate 9 for clamping the pipe.

[0027] The clamping mechanism includes a gear ring 10 rotatably mounted inside the clamping disc 9, a second motor 11 fixedly mounted inside the clamping disc 9, a first gear 12 fixedly mounted on the output end of the second motor 11, a second gear 13 rotatably mounted inside the clamping disc 9, a second threaded rod 14 fixedly mounted on the second gear 13, and a clamping block 15 screwed onto the second threaded rod 14.

[0028] The output end of the first motor 8 passes through the movable slide rail 6 and is fixedly connected to one end of the first threaded rod 7. The first threaded rod 7 passes through the clamping disc 9 and has a threaded hole inside that matches the first threaded rod 7. The first gear 12 meshes with the gear ring 10, and the second gear 13 meshes with the gear ring 10.

[0029] When using this pipe bending machine, firstly, place the base plate 1 in a suitable position. Then, insert one end of the pipe to be bent for air conditioning processing into the clamping plate 9, passing it between the bending wheel 4 and the bending frame 5. Next, start the second motor 11. The output shaft of the second motor 11 drives the first gear 12, which is fixedly connected to it, to rotate synchronously. The rotation of the first gear 12 drives the meshing gear ring 10 to rotate inside the clamping plate 9. The rotation of the clamping plate 9 drives multiple second gears 13 to rotate synchronously. The rotation of the second gears 13 drives the second threaded rod 14, which is fixedly connected to it, to rotate synchronously. This causes the clamping block 15, screwed onto it, to move inward synchronously until the pipe is clamped. Then, start the first motor 8. The output shaft of the first motor 8 drives the first threaded rod 7, which is fixedly connected to it, to rotate inside the moving slide rail 6. This causes the clamping plate 9 to move along the moving slide rail 6. Finally, through the cooperation between the bending wheel 4 and the bending frame 5, the pipe is bent, preventing bending at the rear end during the front-end bending process and improving the bending quality.

[0030] Furthermore, to facilitate the control of bending table 3 and bending wheel 4 in bending the pipeline, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a mounting bracket 24 is fixedly connected to the top of the bending table 3, the bending wheel 4 is fixedly mounted on the side surface of the bending wheel 4, and the bending frame 5 is rotatably mounted on the side surface of the bending wheel 4.

[0031] The bending frame 5 has a sliding connection to a movable frame 16 inside, and a clamping wheel 17 is rotatably connected inside the movable frame 16. The bending frame 5 has a screw-on third threaded rod 18 inside, which passes through the bending frame 5. One end of the third threaded rod 18 is movably connected to one side of the movable frame 16, and the other end of the third threaded rod 18 is fixedly connected to a handle 19.

[0032] When using this pipe bending machine, after placing the pipe on one side of the bending wheel 4, turn the handle 19. The rotation of the handle 19 will drive the third threaded rod 18, which is fixedly connected to it, to rotate synchronously, thereby driving the moving frame 16 to move inward. The pipe is clamped by the clamping wheel 17 and the bending wheel 4. Then, by manually turning the handle 19, the bending frame 5 will rotate synchronously, thereby completing the bending of the pipe.

[0033] It should be noted that, in order to guide the pipes during the bending process, such as... Figure 1 , Figure 2 and Figure 3 As shown, a guide frame 20 is fixedly connected to the top of the bending table 3. A fourth threaded rod 22 is screwed into the inside of the guide frame 20. The fourth threaded rod 22 passes through the guide frame 20. A limit rod 23 is slidably connected inside the guide frame 20.

[0034] The limiting rod 23 passes through the guide frame 20. One end of the limiting rod 23 is fixedly connected to the guide plate 21, and one end of the fourth threaded rod 22 is movably connected to one side of the guide plate 21.

[0035] When the pipe bending machine is in use, the pipe is inserted between the bending wheel 4 and the bending frame 5 at one end. It first passes through the guide frame 20, and then the fourth threaded rod 22 is rotated. The fourth threaded rod 22 drives the guide plate 21 to move inward until the pipe is clamped. At the same time, the limit rod 23 guides the guide plate 21 during its movement to prevent the guide plate 21 from deviating during the movement, thus improving the stability of use.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
