[0038] 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.
[0039] Example 1, please refer to Figures 1-4 This utility model provides a technical solution: a copper tube flaring device, including a housing 1; a square plate 104, fixedly connected to the inner wall of the housing 1 near the top, and a square groove 105 is provided at the bottom of the square plate 104; a threaded screw 106, movably connected to both sides of the inner wall of the square groove 105, and a slider 107 is threadedly connected to the outer surface of the threaded screw 106; a long rod 108, fixedly connected to the bottom of the slider 107, and a fixing plate 109 is fixedly connected to the bottom end of the long rod 108; a second motor 110, fixedly connected to the inner wall of the fixing plate 109, and a round shaft 113 is fixedly connected to the output end of the second motor 110; and a fan 11. 4. Fixedly connected to the bottom end of the round shaft 113; the disc 111 is fixedly connected to the bottom of the fixing plate 109, and multiple heating plates 112 are fixedly connected to the bottom of the disc 111; the motor 103 is fixedly connected to one side of the outer surface of the housing 1, and the output end of the motor 103 is fixedly connected to one end of the threaded screw 106; the outer shell 115 is fixedly connected to the bottom of the disc 111, and a sealing door 101 is connected to one side of the outer surface of the housing 1 via a hinge, and a handle 102 is fixedly connected to one side of the outer surface of the sealing door 101; a vertical plate 2 is fixedly connected to the inner wall of the housing 1 near the bottom, and a chuck 201 is fixedly installed on one side of the outer surface of the vertical plate 2.
[0040] In this embodiment, during use, the sealing door 101 is first opened, and one end of the copper tube to be flared is fixed and clamped using the chuck 201. Then, the controller starts motor 103, and the output end of motor 103 drives the threaded screw 106 to rotate forward. Through the continuous rotation of the threaded screw 106, the slider 107 gradually moves to directly above the preheating part of the copper tube. Then, the controller starts multiple heating plates 112, and the multiple heating plates 112 begin to heat up. Then, the operator starts motor 2 110 using the controller. The output end of motor 2 110 drives the circular shaft 113 to rotate forward, and the circular shaft 113 drives the fan 114 to blow out hot air. At the same time, the outer casing 115 directs the hot air towards... Blowing in a designated direction, once one end of the copper tube is heated to a certain temperature, the worker uses heat-resistant gloves to rotate the copper tube to ensure even heating. The chuck 201 can be adjusted for tightness by the worker. After one end of the copper tube is preheated, the worker uses the controller to start the electric telescopic rod 202. The output end of the electric telescopic rod 202 gradually pushes the flaring mandrel body 204 into the copper tube to flare it. After flaring, the copper tube is allowed to cool before the finished product is removed. This process allows for preheating of harder or thicker copper tubes during flaring operations, reducing material hardness and facilitating subsequent operations, thus improving the overall efficiency of the copper tube flaring device.
[0041] Example 2, as Figures 1-4 As shown, an electric telescopic rod 202 is fixedly connected to one side of the inner wall of the housing 1 near the bottom. A clamping plate 203 is fixedly connected to the output end of the electric telescopic rod 202. A flared mandrel body 204 is provided on both sides of the inner wall of the clamping plate 203. An extension plate 206 is fixedly connected to one side of the outer surface of the clamping plate 203. A pin 205 is movably embedded inside the extension plate 206. A spring 207 is fixedly connected to one side of the pin 205. One end of the spring 207 is fixedly connected to the outer surface of the extension plate 206. The outer surface of the pin 205 is movably embedded inside the flared mandrel body 204.
[0042] In this embodiment, when it is necessary to quickly replace the flaring mandrel body 204, the operator manually pulls out the pin 205 and keeps the pin 205 in the pulled-out state. Then, the original flaring mandrel body 204 is removed, and the new flaring mandrel body 204 is inserted into the clamping plate 203. Then, the pin 205 is released, and the pin 205 is quickly rebounded into the interior of the flaring mandrel body 204 due to the elastic force of the spring 207. This makes it easy to quickly replace the flaring mandrel body 204 when performing flaring operations after preheating, thus improving the practicality of the copper tube processing flaring device.
[0043] Working Principle: In use, first open the sealing door 101 and clamp one end of the copper tube to be flared using the chuck 201. Then, start motor 103 using the controller. The output of motor 103 drives the threaded screw 106 to rotate forward. Through the continuous rotation of the threaded screw 106, the slider 107 gradually moves to directly above the preheating area of the copper tube. Then, start multiple heating plates 112 using the controller. The heating plates 112 begin to heat up. Next, start motor 2 110 using the controller. The output of motor 2 110 drives the circular shaft 113 to rotate forward. The circular shaft 113 drives the fan 114 to blow hot air out. Simultaneously, the outer casing 115 directs the hot air in a designated direction. When one end of the copper tube is heated to a certain degree, the operator uses heat-resistant gloves to rotate the copper tube to ensure even heating. The chuck 201 can be adjusted according to the operator's tightness. After one end of the copper tube is preheated, the operator starts the electric telescopic rod 20 using the controller. 2. The output end of the electric telescopic rod 202 gradually pushes the flaring mandrel body 204 into the copper tube to flare the copper tube. After the flaring is completed, the copper tube is cooled and the finished product can be removed. This allows for preheating of harder or thicker copper tubes during flaring operations, reducing material hardness and facilitating subsequent operations, thus improving the overall efficiency of the copper tube flaring device. When a quick replacement of the flaring mandrel body 204 is needed, the operator manually pulls out the pin 205 and keeps it in the pulled-out state. Then, the original flaring mandrel body 204 is removed, and the new flaring mandrel body 204 is inserted into the clamping plate 203. After releasing the pin 205, the pin 205 is quickly rebounded into the flaring mandrel body 204 due to the elastic force of the spring 207. This allows for quick replacement of the flaring mandrel body 204 after preheating, improving the practicality of the copper tube flaring device.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
