Description

Technical Field

[0002] Portable copper capillary bending tool is a small, easy-to-carry instrument that can bend copper capillary tubes. It can be used in fields such as air conditioning and instrumentation that involve the use of copper capillary tubes, helping operators to quickly and accurately bend copper capillary tubes into the required shape to meet different installation space and routing requirements, thereby improving installation efficiency and quality.

[0003] For example, Chinese Patent Application No. 202020678242.7 discloses a copper tube bending device, including a base and a bending mechanism, a fixing mechanism, and a positioning mechanism mounted on the base. The fixing mechanism is used to place the copper tube between the bending mechanism and the base. The fixing mechanism is movable towards or away from the bending mechanism to fix or loosen the copper tube. The positioning mechanism is movably mounted on the base and abuts against one end of the copper tube to determine the bending length. The bending mechanism determines the bending angle of the copper tube and bends it. This copper tube bending device ensures the accuracy of the bending length by setting a positioning mechanism and accurately controls the bending angle of the copper tube by setting a bending mechanism. The bending length and angle do not require multiple adjustments, saving time, increasing production efficiency, and resulting in high-quality copper tube bending.

[0004] In practical use, portable copper capillary bending devices are typically operated manually to bend copper tubes. However, prolonged manual operation can lead to muscle fatigue in the operator's hands due to repeated exertion, resulting in discomfort such as hand soreness. This fatigue also reduces the operator's precision and strength control, decreasing the bending efficiency of the copper tubes.

[0005] Therefore, it is necessary to redesign and modify the portable copper capillary bending tool to effectively prevent a decrease in its operating efficiency. Utility Model Content

[0009] As a preferred embodiment of this utility model, the manual lifting mechanism includes a linkage plate movably connected to the surface of the transmission cylinder via a bearing. The surface of the support frame is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the surface of the linkage plate. Handles are fixedly connected to the left and right sides of the linkage plate. The handles are used to facilitate gripping with fingers and pulling upward, thereby facilitating the removal of the bent copper tube.

[0010] As a preferred embodiment of this invention, a spring is fixedly connected to the upper side of the transmission cylinder, and the upper end of the spring is fixedly connected to the lower side of the support frame.

[0011] As a preferred embodiment of this utility model, a limiting frame is fixedly connected to the surface of the linkage plate, and the inner side of the limiting frame slides on the surface of the support frame.

[0012] As a preferred embodiment of this invention, a protective box is provided on the upper side of the motor, and the lower side of the protective box is fixedly connected to the upper side of the support frame.

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.

[0018] like Figures 1 to 4 As shown, the portable copper capillary bending tool provided by this utility model includes a base plate 1, a bending mechanism is provided on the upper side of the base plate 1, the bending mechanism includes a fixing plate 2 fixedly connected to the upper side of the base plate 1, a groove 3 is provided on the upper side of the fixing plate 2, a copper tube 4 is movably connected to the inner wall of the groove 3, a short rod 5 is movably connected to the left side of the copper tube 4, the short rod 5 is used to bend the copper tube 4, a rotating cylinder 6 is fixedly connected to the upper end of the short rod 5, a limit rod 7 is slidably connected to the inner wall of the rotating cylinder 6, the lower end of the limit rod 7 is fixedly connected to the top of the base plate 1, and a driving mechanism is provided on the upper side of the copper tube 4.

[0019] refer to Figure 4 The drive mechanism includes a support frame 8 fixedly connected to the front side of the base plate 1. A motor 9 is fixedly connected to the top of the support frame 8. A transmission rod 10 is fixedly connected to the lower output shaft of the motor 9. A transmission cylinder 11 is connected to the surface of the transmission rod 10. The transmission cylinder 11 is slidably sleeved on the surface of the limit rod 7. The lower side of the transmission cylinder 11 is fixedly connected to the upper side of the rotating cylinder 6. A manual lifting mechanism is provided on the upper side of the base plate 1.

[0020] As a technical optimization of this utility model, an electric bending operation is realized by setting a driving mechanism, which improves the bending efficiency; at the same time, a manual lifting mechanism is set to increase the flexibility of manual operation and facilitate the removal of the bent copper tube 4.

[0021] refer to Figure 3 The manual lifting mechanism includes a linkage plate 12 that is movably connected to the surface of the transmission cylinder 11 via a bearing. The surface of the support frame 8 is provided with a sliding groove 13. The inner wall of the sliding groove 13 is slidably connected to the surface of the linkage plate 12. Handles 14 are fixedly connected to the left and right sides of the linkage plate 12. The handles 14 are used to make it easy for fingers to grip and pull upward, thereby making it easy to remove the bent copper tube 4.

[0022] As a technical optimization of this utility model, by setting a manual lifting mechanism, it is convenient for operators to remove the bent copper tube 4, making the operation simple and convenient and improving work efficiency.

[0023] refer to Figure 4 A spring 15 is fixedly connected to the upper side of the transmission cylinder 11, and the upper end of the spring 15 is fixedly connected to the lower side of the support frame 8.

[0024] As a technical optimization of this utility model, by setting spring 15, the transmission cylinder 11 and other components can be automatically reset, preparing for the next operation and ensuring the stability and reliability of the device.

[0025] refer to Figure 2 A limiting frame 16 is fixedly connected to the surface of the linkage plate 12, and the inner side of the limiting frame 16 slides on the surface of the support frame 8.

[0026] As a technical optimization of this utility model, the stability of the device is further enhanced by setting a limiting frame 16. The inner side of the limiting frame 16 is slidably connected to the surface of the support frame 8, which restricts the movement trajectory of the linkage plate 12, prevents the linkage plate 12 from shifting or shaking during up and down movement, ensures that the manual lifting mechanism can work accurately and stably, and improves the operating accuracy of the entire device.

[0027] refer to Figure 1 A protective box 17 is provided on the upper side of the motor 9, and the lower side of the protective box 17 is fixedly connected to the upper side of the support frame 8.

The protective box 17 can block these harmful factors, prevent damage to the motor 9, extend the service life of the motor 9, and at the same time improve the safety and reliability of the device, ensuring that the device can work normally in various environments.

[0029] The working principle and usage process of this utility model are as follows: In use, the copper tube 4 is first placed in the groove 3 of the fixed plate 2. The motor 9 in the drive mechanism is started, and the output shaft of the motor 9 drives the transmission rod 10 to rotate. The transmission rod 10 drives the rotating cylinder 6 to rotate around the limiting rod 7 via the transmission cylinder 11. The short rod 5 connected to the rotating cylinder 6 rotates accordingly and applies force to the copper tube 4, causing the copper tube 4 to bend and deform within the groove 3. When manual operation or removal of the bent copper tube 4 is required, the manual lifting mechanism is used. By gripping the handle 14 on the linkage plate 12 and pulling upwards, the linkage plate 12 drives the transmission cylinder 11 to move upwards, thus facilitating the removal of the copper tube 4 wrapped around the surface of the limiting rod 7. During the upward and downward movement of the transmission cylinder 11, the spring 15 acts as a buffer and reset mechanism, while the protective box 17 protects the motor 9. This avoids the efficiency reduction caused by prolonged manual operation of the portable copper capillary bending device, making it easy to use.

[0030] In summary, when this utility model is used, the bending mechanism, the driving mechanism, and the manual lifting mechanism can electrically drive the copper tube 4 to bend, avoiding the efficiency reduction caused by long-term manual operation of the portable copper capillary processing bending device, thus giving it the advantage of being easy to use.
