Description

Technical Field

[0001] This utility model relates to the field of refrigerator manufacturing applications, and in particular to a refrigerator condenser tube bending device. Background Technology

[0002] As a crucial component of the refrigerator's refrigeration system, the shape and size of the condenser coil significantly impact cooling performance. Traditional condenser coil bending methods often rely on manual operation or simple mechanical devices, requiring each coil to be clamped and bent individually—a cumbersome and time-consuming process. This not only increases production costs but also limits production line capacity.

[0003] Secondly, if the clamping force or bending angle is not properly controlled during the bending process, scratches or indentations can easily be caused to the surface of the condenser tube. These damages not only affect the appearance of the condenser tube, but may also reduce its heat dissipation performance and service life. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a refrigerator condenser tube bending device, which solves the following technical problems: how to improve the accuracy and efficiency of condenser tube bending, and how to enhance the flexibility and automation of the device.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A refrigerator condenser tube bending device includes a processing table, a top plate above the processing table, support columns fixedly connected to the four corners of the top of the processing table, the tops of the support columns fixedly connected to the top plate, guide columns fixedly connected to the top of the processing table, a rotating shaft rotatably connected to the bottom of the top plate, a positioning box fixedly connected to the top of the top plate, a rotating fixture fixedly connected to the bottom of the rotating shaft, clamping plates symmetrically slidably connected inside the rotating fixture, push rod motors installed on both sides of the rotating fixture, the output ends of the push rod motors fixedly connected to the corresponding clamping plates, and a drive motor installed on the top of the top plate, the output end of the drive motor fixedly connected to one end of the rotating shaft.

[0007] Preferably, the top plate has a movable hole to provide space for the clamping plate driven by the push rod motor to move up. When the clamping plate clamps the condenser tube to complete the bending action and needs to be raised and reset, the movable hole ensures that the clamping plate and its connecting parts will not interfere with the top plate, thereby ensuring the smooth operation of the equipment.

[0008] Preferably, a pressure rod is slidably connected inside the positioning box, and a threaded rod is threadedly connected to the top of the positioning box. The bottom end of the threaded rod is fixedly connected to the pressure rod. By rotating the threaded rod, the height of the pressure rod can be adjusted to accommodate different numbers of condenser tubes and achieve flexible clamping.

[0009] Preferably, the top end of the threaded rod is fixedly connected with a hand wheel, and the rotation of the threaded rod can be easily adjusted by rotating the hand wheel, thereby realizing the accurate adjustment of the height of the pressing rod.

[0010] Preferably, the top of the positioning box is symmetrically slidably inserted with a sliding rod, and the bottom end of the sliding rod is fixedly connected with the pressing rod, so that the sliding rod slides up and down when the pressing rod moves up and down, thereby ensuring that the pressing rod moves stably along the predetermined path and avoiding unnecessary deviation or inclination.

[0011] Preferably, the bottom of the pressing rod is provided with a groove, and the pressing rod can be more closely and uniformly pressed against the condenser pipe through the groove, thereby improving the pressing effect.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. The utility model discloses a rotating tool and a symmetrically slidably connected clamping plate in the rotating tool, which can clamp and bend multiple condenser pipes at the same time, thereby significantly improving production efficiency, reducing the time and labor cost required for bending a single condenser pipe, and ensuring the consistency and accuracy of multiple condenser pipes in the bending process, avoiding problems such as size deviation or inconsistent shape caused by bending one by one.

[0014] 2. The height adjustment mechanism of the pressing rod in the positioning box can flexibly adapt to different numbers of condenser pipes, so that the equipment can be widely applied to the bending needs of various refrigerator condenser pipes without the need to replace or adjust additional parts, and the groove at the bottom of the pressing rod further enhances the adhesion to the condenser pipe, thereby improving the pressing effect and bending precision.

DETAILED DESCRIPTION

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The refrigerator condenser tube bending equipment has a processing table 1;

[0022] like Figures 1 to 4 As shown, a top plate 2 is provided above the processing table 1. Support columns 3 are fixedly connected to the four corners of the top of the processing table 1. The top of the support columns 3 is fixedly connected to the top plate 2. Guide columns 4 are fixedly connected to the top of the processing table 1. A rotating shaft 5 is rotatably connected to the bottom of the top plate 2. A positioning box 6 is fixedly connected to the top of the top plate 2. A rotating fixture 7 is fixedly connected to the bottom of the rotating shaft 5. Clamping plates 8 are symmetrically slidably connected inside the rotating fixture 7. Push rod motors 9 are installed on both sides of the rotating fixture 7. The output end of the push rod motor 9 is fixedly connected to the corresponding clamping plate 8. A drive motor 10 is installed on the top of the top plate 2. The output end of the drive motor 10 is fixedly connected to the corresponding end of the rotating shaft 5.

[0023] The condenser tubes pass through the positioning box 6 in a stacked manner, with the bending section located on one side of the guide post 4. When preparing to bend, the push rod motor 9 starts, driving the clamping plate 8 connected to its output end to descend, positioning it on both sides of the condenser tube to be bent. Then, the drive motor 10 starts, its output end driving the rotating fixture 7 to rotate via the rotating shaft 5. Because the clamping plate 8 is attached to both sides of the condenser tube, the condenser tube bends as the rotating fixture 7 rotates. During this process, the guide post 4 acts as a guide, ensuring that the condenser tube can be bent smoothly around the guide post 4 to form the desired curved shape.

[0024] like Figures 1 to 4 As shown, the top plate 2 has a movable hole 11. When the clamping plate 8 clamps the condenser tube and completes the bending, it needs to rise back to the initial position. At this time, the movable hole 11 ensures that the top of the clamping plate 8 will not be obstructed during the rising process.

[0025] like Figures 1 to 4 As shown, a pressure rod 12 is slidably connected inside the positioning box 6, and a threaded rod 13 is threadedly connected to the top of the positioning box 6. The bottom end of the threaded rod 13 is fixedly connected to the pressure rod 12. The pressure rod 12 inside the positioning box 6 is height-adjusted through the threaded rod 13. Depending on the number and stacking height of the condenser tubes, the threaded rod 13 can be rotated to move the pressure rod 12 up and down, thereby pressing the condenser tubes inside the positioning box 6 to ensure stability during bending.

[0026] like Figures 1 to 4 As shown, a handwheel 14 is fixedly connected to the top of the threaded rod 13. The handwheel 14 makes it easier and more convenient to rotate the threaded rod 13, and the height of the pressure rod 12 can be easily adjusted by rotating the handwheel 14.

[0027] As Figures 1 to 4 shown, the positioning box 6 top symmetrical sliding plug-in slide bar 15, the bottom end of the slide bar 15 and the pressing rod 12 are fixedly connected, when the pressing rod 12 moves up and down, the slide bar 15 plays a guiding and stabilizing role, ensuring that the pressing rod 12 can move smoothly and will not shake or deviate.

[0028] As Figures 1 to 4 shown, the bottom of the pressing rod 12 is provided with a groove 16, the groove 16 makes the pressing rod 12 more closely with the condenser pipe, increases the contact area between the pressing rod 12 and the condenser pipe, improves the pressing effect, and also helps to protect the surface of the condenser pipe from damage.

[0029] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
