[0002] Air conditioning copper pipe bending device is a professional equipment used to bend rigid copper pipes in air conditioning systems into specific angles, radii of curvature or shapes according to design requirements. Its core function is to protect the copper pipes during the bending process, to prevent the pipe walls from denting, cracking or cross-sectional deformation, and to ensure that the bent copper pipes still meet the refrigerant flow efficiency and structural strength requirements of the air conditioning system.

[0003] However, in the existing equipment, after the copper tube has been bent, the guide roller used to limit the copper tube is difficult to disassemble. This problem makes it difficult to remove the bent copper tube from the equipment smoothly, which will cause inconvenience to subsequent operations. Utility Model Content

[0004] The purpose of this utility model is to provide a bending device for air conditioning copper pipes. By setting up a disassembly part, the problem of the complicated disassembly process of the guide roller used to limit the copper pipe after the bending operation is completed is solved. This problem makes it difficult to remove the bent copper pipe from the device smoothly, which will cause inconvenience to subsequent operations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a bending device for air conditioning copper pipes, comprising a workbench and further comprising: a disassembly section disposed on the top of the workbench; a processing section disposed on the top of the workbench; the disassembly section comprising a disassembly assembly mounted on the workbench; and a drive assembly mounted on the top of the workbench; the disassembly assembly comprising a support plate fixedly connected to the top of the workbench, a guide roller rotatably connected to the top of the support plate, and a disassembly guide roller rotatably connected to the top of the support plate; copper pipes are disposed on the outer walls of the guide roller and the disassembly guide roller on their adjacent sides; a gear is fixedly connected to the outer wall of the disassembly guide roller; a slide rail is fixedly connected to the top of the support plate; a transmission component is disposed on the slide rail; the slide rail is located on the front top of the support plate; the transmission component comprises a rack slidably connected within the slide rail, the rack meshing with the gear; and the output end of a hydraulic push rod is fixedly connected to the rack.

[0006] Furthermore, the processing unit includes a bending assembly mounted on top of the worktable; and a fixing assembly disposed on top of the worktable.

[0007] Furthermore, the drive assembly includes a mounting plate fixedly connected to the top of the worktable, and a hydraulic push rod is fixedly connected to the left side of the mounting plate. The output end of the hydraulic push rod extends outside the mounting plate and is slidably connected to the mounting plate.

[0008] Furthermore, the bending assembly includes a rotating shaft disposed on the top of the workbench, a bending push rod fixedly connected to the outer wall of the rotating shaft, the bending push rod contacting the copper tube, a driving component disposed on the rotating shaft, the bending push rod being L-shaped, the driving component including a motor disposed on the top of the workbench, the output shaft of the motor being fixedly connected to the rotating shaft via a coupling, a motor slot being provided on the top of the workbench, and the motor being located within the motor slot.

[0009] Furthermore, the fixing assembly includes a rectangular frame fixedly connected to the top of the workbench, a second guide roller rotatably connected to the rectangular frame, two slide rods fixedly connected to the top of the rectangular frame, a top plate fixedly connected to the top of the two slide rods, a slide frame slidably connected to the outer walls of the two slide rods, a third guide roller rotatably connected to the slide frame, and a movable component provided on the top plate.

[0010] This utility model has the following beneficial effects: 1. By setting up a disassembly section, when the copper tube needs to be disassembled after bending, the hydraulic push rod is activated to push the rack to move to the right along the slide rail. Because the rack meshes with the gear on the outer wall of the disassembly guide roller on the support plate, the rack moving to the right will drive the gear and the disassembly guide roller to rotate to the disassembly position, making it easy to remove the bent copper tube between the guide roller and the disassembly guide roller. This setting can simplify the copper tube disassembly process, reduce operation time, and improve overall work efficiency. 2. By setting up a processing section, when in use, first pass the copper tube between guide roller 2 and guide roller 3, and then pass it out between guide roller 1 and disassembly guide roller. When it is necessary to fix the copper tube, turn the manual turntable on the screw to drive the screw to rotate. When the screw rotates, it is guided by two slide rods, which drive the slide frame and guide roller 3 to move closer to guide roller 2 on the rectangular frame, clamping the copper tube between them. This setting can flexibly adjust the fixing force of the copper tube to ensure the stability of the position during subsequent bending and avoid displacement.

With the processing section 3 in place, during use, the copper tube 214 can first be passed between guide roller 2 322 and guide roller 3 326, and then pass through between guide roller 1 212 and disassembly guide roller 213. If it is necessary to fix the copper tube 214, the manual turntable 328 on the screw 327 can be rotated. The manual turntable 328 drives the screw 327 to rotate. When the screw 327 rotates, it will be guided by the two sliding rods 323, thereby driving the sliding frame 325 and its guide roller 3 326 to move closer to the guide roller 2 322 on the rectangular frame 321, thereby clamping and fixing the copper tube 214 between them. Through this setting, the fixing force on the copper tube 214 can be flexibly adjusted to ensure its stable position during subsequent bending and avoid... To prevent misalignment, the copper tube 214 can be passed between guide roller 222 and guide roller 326, and then passed between guide roller 12 and disassembly guide roller 213. If it is necessary to fix the copper tube 214, the manual turntable 328 on the screw 327 can be rotated. The manual turntable 328 drives the screw 327 to rotate. When the screw 327 rotates, it will be guided by the two slide rods 323, thereby driving the slide frame 325 and its guide roller 326 to move closer to the guide roller 222 on the rectangular frame 321, thereby clamping and fixing the copper tube 214 between them. With this setting, the fixing force of the copper tube 214 can be flexibly adjusted to ensure its stable position during subsequent bending and avoid misalignment.

[0019] It should be noted that the control of the motor 311 and the hydraulic push rod 222 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be implemented using existing technologies, such as PLC.
