Detailed Implementation

[0023] 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.

[0024] Reference Figure 1 , Figure 2 , Figure 4 This utility model provides an embodiment of a radiator copper tube outer diameter reduction machine, including a workbench 1 as the supporting foundation of the entire equipment. A fixed plate 3 is fixedly connected to the top left side of the workbench 1. The fixed plate 3 is a rectangular flat plate structure, which plays a role in stabilizing the support. A reduction device 4 is fixedly connected to the top of the fixed plate 3. The reduction device 4 is a device with power output and pressure application functions. A reduction mold 5 is rotatably connected to its output end. The reduction mold 5 is cylindrical and has a reduction cavity of a specific shape inside. During rotation, it can apply radial pressure to the end of the copper tube, causing plastic deformation of the copper tube end material, thereby reducing the outer diameter of the copper tube. A pushing component is fixedly connected to the top right side of the workbench 1 for pushing the copper tube to the reduction mold 5. A feeding component is fixedly connected to the top of the workbench 1 for placing and initially positioning the copper tube to be processed. Two support columns a11 are fixedly connected to the top of the workbench 1, vertically fixed to the top of the workbench 1. A guide component is fixedly connected to the adjacent side of the workbench 1. The guide component is used to guide and straighten the copper tube during the pushing process. Two support columns b23 are fixedly connected to the top of the workbench 1. The two support columns b23 are also vertically fixed to the top of the workbench 1. An automatic feeding component is fixedly connected to the adjacent side of the two support columns b23. The automatic feeding component is used to transport the copper tube that has completed the narrowing process to the collection position. The feeding component includes a limiting block 8. The limiting block 8 is a cuboid block structure. Its bottom is fixedly connected to the top of the workbench 1. A limiting groove 9 is opened inside the limiting block 8. The limiting groove 9 is a rectangular groove with a certain slope. Using gravity, the copper tube moves automatically laterally during the feeding process to ensure that the copper tube can fall into the copper tube groove in the limiting block 8. A feeding plate 10 is fixedly connected to the front side of the limiting block 8. The feeding plate 10 is an inclined flat plate structure with a smooth upper surface. It can be used as a component to assist in placing or guiding the copper tube to the limiting groove 9, so that the operator can place the copper tube in the appropriate position.

[0025] The pushing component includes cylinder a6, a common pneumatic actuator. Its bottom is fixedly connected to the top of the worktable 1. A push rod a7 is fixedly connected to the drive end of cylinder a6. Push rod a7 is a cylindrical rod structure, externally slidably connected to the inside of the limiting block 8. When cylinder a6 is activated, the drive end pushes push rod a7 forward within the limiting block 8. The front end of push rod a7 contacts the copper tube in the limiting groove 9, pushing the copper tube forward along the limiting groove 9, delivering the copper tube to the narrowing mold 5 of the narrowing device 4. The automatic unloading component includes two rollers 24, which are semi-cylindrical hollow structures. Their opposite sides are fixedly connected to the adjacent sides of two support columns b23. A gap is left between the two rollers 24, allowing the narrowed copper tube to fall downwards under the rotation of the roller 28. A connecting plate b25 is fixedly connected to the inner side of the feed inlet 29 and the roller 24. The connecting plate b25 is a rectangular flat plate structure, which serves as a connection and support. A motor 26 is fixedly connected to the left side of the connecting plate b25. The motor 26 is a power source, and a connecting column b27 is fixedly connected to its drive end. The connecting column b27 is a cylindrical rod structure, and a roller 28 is rotatably connected to its outside. The roller 28 is a cylindrical structure with a smooth surface and grooves to restrict the rotation of the copper tube. Driven by the motor 26, the connecting column b27 drives the roller 28 to rotate. The copper tube after narrowing moves downward along the roller 28 under the rotation of the roller 28. Automatic feeding is achieved by utilizing the gap between the two rollers 24. The outside of the connecting column b27 is rotatably connected to the inside of the connecting plate b25 to ensure that the connecting column b27 can rotate stably.

[0026] Reference Figure 3The guiding assembly includes a guiding device housing 12, which is a rectangular hollow shell structure. Its exterior is fixedly connected to two support columns a11 on adjacent sides, providing support and protection for the entire guiding assembly, preventing damage to internal components from external impacts, and providing installation space for internal parts. A connecting column a13 is fixedly connected to the top of the inner part of the guiding device housing 12. The connecting column a13 is a cylindrical rod-shaped structure with a smooth surface and good rotational performance. A gear 14 is rotatably connected to the exterior of the connecting column a13. The gear 14 is circular with evenly distributed teeth and can rotate freely on the connecting column a13. Power transmission and motion conversion are achieved through meshing with a rack 19. Two guide rails 15 are fixedly connected to the top of the inner part of the guiding device housing 12. The guide rails 15 are elongated track structures. The cross-section is "I" shaped, providing good guiding performance and stability. Two sliders 16 are slidably connected to the outside of the two guide rails 15. The sliders 16 are block structures with grooves inside that match the guide rails 15, allowing them to slide smoothly along the length of the guide rails 15, ensuring the straightness and stability of the sliders 16 during movement. A connecting plate a17 is fixedly connected to the adjacent side of the two sliders 16. The connecting plate a17 is a rectangular flat plate structure that connects the two sliders 16, enabling them to move synchronously. A guide block 18 is fixedly connected to the outside of the connecting plate a17. The guide block 18 is an arc-shaped block structure whose curvature matches the outer diameter of the copper tube. It guides and straightens the copper tube during movement, preventing it from tilting during the pushing process and ensuring that the copper tube can accurately enter the constriction mold 5.

[0027] Both connecting plates a17 are fixedly connected to the top of racks 19. The racks 19 are elongated structures with teeth that mesh with gears 14. When the gears 14 rotate, the meshing of the teeth drives the two racks 19 to move synchronously in opposite directions, thereby causing the two connecting plates a17 and guide blocks 18 to move synchronously, adjusting the position of the guide blocks 18. A cylinder b20 is fixedly connected to the top of the guide device housing 12. The cylinder b20 is a common pneumatic actuator with stable power output capability. A push rod b21 is fixedly connected to the drive end. The push rod b21 is a cylindrical rod structure that can extend and retract in a straight line under the drive of the cylinder b20. A connecting block 22 is fixedly connected to the front side of the push rod b21. The connecting block 22 is a block structure that connects the push rod b21 and the slider 16. The left side of the connecting block 22 is fixedly connected to the outside of the slider 16. When the cylinder b20 is started, the drive end pushes the push rod b21 forward. The push rod b21 drives the slider 16 to slide on the guide rail 15 through the connecting block 22, thereby driving the entire guide assembly to move and realize the guiding and straightening function of the copper tube.

[0028] Reference Figure 1 The bottom of the workbench 1 is fixedly connected with four fixed columns 2. The fixed columns 2 are cylindrical solid structures with flat bottoms and large support areas, which can stably support the entire radiator copper tube outer diameter reduction machine on the ground, ensuring that the processing accuracy will not be affected by shaking during the operation of the equipment. At the same time, the four fixed columns 2 are evenly distributed at the four corners of the bottom of the workbench 1, providing balanced support for the workbench 1. The workbench 1 has a feeding port 29 inside. The feeding port 29 is a rectangular through hole structure, and its size is slightly larger than the diameter of the copper tube after the reduction process. It is opened on the workbench 1 near the automatic feeding component, so that the copper tube after the reduction process can fall smoothly into the collection device below through the feeding port 29, realizing the automatic feeding function of the copper tube.

[0029] Two slide rails 30 are fixedly connected to the bottom of the workbench 1. Each slide rail 30 has a long, narrow groove structure with a smooth sliding surface inside. Limiting protrusions on both sides prevent the slide plate 31 from dislodging. The two slide rails 30 are parallel to each other and horizontally fixed to the bottom of the workbench 1, providing a stable track for the slide plate 31 to slide smoothly in a straight line. Slide plates 31 are slidably connected inside each of the two slide rails 30. The bottom of the slide plate 31 contacts the sliding surface of the slide rail 30, allowing it to slide freely along the length of the slide rail 30. The sliding process of the slide plate 31 is smooth and stable, without any slippage. If a jamming occurs, the sliding of the slide plate 31 can move the connected collection box 32, facilitating the loading and unloading of the collection box 32. The collection box 32 is fixedly connected to the adjacent side of the two slide plates 31. The collection box 32 is a rectangular box-shaped structure with an open top, and its internal space is sufficient to accommodate a certain number of copper tubes that have undergone the narrowing process. The collection box 32 is slidably connected to the slide rail 30 through the slide plate 31, and can be easily pulled out or pushed in from the bottom of the worktable 1. When the collection box 32 is full of copper tubes, the collection box 32 can be pulled out, the copper tubes can be removed, and then it can be pushed back to its original position to continue collecting. The operation is simple and convenient.

[0030] Working principle: The copper tube to be shortened is placed in the limiting groove 9 of the limiting block 8 of the feeding assembly. The limiting groove 9 provides initial positioning for the copper tube, preventing it from shifting during the initial feeding stage. The unloading plate 10 can serve as an auxiliary component for placing or guiding the copper tube to the limiting groove 9. The cylinder a6 of the pushing assembly is activated, and the driving end of the cylinder a6 pushes the push rod a7 to slide forward inside the limiting block 8. The front end of the push rod a7 contacts the copper tube in the limiting groove 9 and pushes the copper tube forward along the limiting groove 9. During the forward movement of the copper tube, the guiding assembly plays its role, and the cylinder b20 is activated, with its driving end pushing the push rod b21 forward. When the push rod b21 moves, the connecting block 22 on the front side drives the connected slider 16 to slide on the guide rail 15. When one slider 16 moves, the other slider 16 will also move synchronously through the transmission of the rack 19 and the gear 14, thereby driving the two connecting plates a17 and the guide block 18 fixed on them to move synchronously. The guide block 18 plays a guiding and straightening role for the moving copper tube, ensuring that the copper tube can enter the shrinking mold 5 of the shrinking device 4 accurately and stably, avoiding the copper tube from deflecting during the movement and affecting the shrinking quality. The movement of the guide block 18 can adapt to different copper tube sizes, enhancing its flexibility.

[0031] When the copper tube reaches the position of the necking mold 5, the necking device 4 is activated, and its output end drives the necking mold 5 to rotate. The necking mold 5 applies radial pressure to the end of the copper tube, causing the material at the end of the copper tube to undergo plastic deformation under pressure, thereby reducing the outer diameter of the copper tube. After the necking process is completed, the automatic feeding component starts working, the motor 26 is activated, and the drive end of the motor 26 drives the connecting column b27 to rotate, which in turn drives the roller 28 to rotate. The necked copper tube, driven by the rotation of the roller 28, falls into the collection box 32 through the gap between the two rollers 24 and the feeding port 29 opened inside the worktable 1. The collection box 32 is slidably connected to the slide rail 30 through the slide plate 31, which facilitates the removal of the copper tube after it is full.
