Description

Technical Field

[0001] The utility model relates to the technical field of automotive air conditioners, and particularly relates to a bending device for aluminum pipes of a bicycle air conditioner. Background Art

[0002] The condenser and evaporator of an automotive air conditioner need to be connected by a refrigerant pipeline. Since the condenser and evaporator are far apart, the connecting pipeline is very long and is arranged in a winding manner among the gaps of many components in the engine compartment. Once installed, it is basically impossible to disassemble and replace. This requires that the life of the refrigerant pipeline be very long, equivalent to the life of the whole vehicle. Therefore, it is best that the whole pipe is made of corrosion-resistant aluminum pipe.

[0003] During the production process, in order to adapt to the manufacture of pipelines of various shapes, it is necessary to bend the aluminum pipe. There are various existing bending methods. However, due to the different installation positions of the aluminum pipe, there will also be differences in the bending angles. Especially when processing a long arc-shaped aluminum pipe, since the bending angle is small, when using equipment to bend, the force cannot be adjusted according to the force condition during bending, and the aluminum pipe may be damaged. Therefore, this technical solution is proposed for improvement. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiency that the aluminum pipe of the air conditioner is damaged during large-arc processing in the prior art, and to provide a bending device for aluminum pipes of an automotive air conditioner.

[0015] The following describes the preferred embodiments of the present utility model with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0016] See Figures 1 to 3 , the embodiments of the present utility model disclose a bending device for an aluminum tube of an automotive air conditioner, which mainly consists of a bottom plate 1, a support plate 2, a forming plate 3, a pressing wheel 402 and its driving device. The bottom plate 1 serves as the foundation of the entire device. The bottom plate 1 is stably fixed on the ground or the operating table for easy manual operation.

[0017] The support plate 2 is vertically fixed on the bottom plate 1. A track groove 201 is provided on the side of the support plate 2 to guide the movement track of the pressing wheel 402. The track groove 201 is set according to the angle to be bent. The support plate 2 is made of steel plate to ensure sufficient rigidity and stability to support various forces of the forming plate 3 and the pressing wheel 402 during the working process. According to the specific bending shape requirements of the aluminum tube, multiple forming plates 3 can be designed. Each forming plate 3 is provided with continuous forming grooves 301. The shape of the forming grooves 301 matches the target bending shape of the aluminum tube to ensure the accuracy of bending. The forming plate 3 is connected to the support plate 2 by bolts to ensure the structural strength of the forming plate 3 and reduce the displacement between the forming plate 3 and the support plate 2 during processing. The multiple arranged forming plates 3 can be produced using processing waste, and multiple different-angle track grooves 201 can be set on the same support plate 2. On the premise of ensuring the structural strength, it can cooperate with different forming plates 3 to facilitate production according to different bending requirements, which is convenient to use and simple to adjust.

[0018] The pressing wheel 402 is slidably arranged along the track groove 201. It applies pressure to the aluminum tube through its rolling action to guide the aluminum tube to be bent along the shape of the forming groove 301. A rotating shaft is arranged in the middle of the pressing wheel 402, and this rotating shaft is inserted into the through groove on the support plate 2 to ensure that the pressing wheel 402 can smoothly move along the preset track groove 201. The driving device adopts a rocker arm 4 hinged on the bottom plate 1. The rocker arm 4 can freely rotate along the vertical plane of the support plate 2. A guiding groove 401 is arranged in its length direction. The rotating shaft of the pressing wheel 402 is slidably connected to the guiding groove 401. By rotating the rocker arm 4, the pressing wheel 402 is driven to move along the track groove 201, thereby realizing the bending operation of the aluminum tube. A positioning hole 101 is arranged on the bottom plate 1 between the pressing wheel 402 and the starting point of the forming groove 301. When in use, one end of the aluminum tube is vertically inserted into the positioning hole 101 to fix and position one end of the aluminum tube and ensure stability during processing.

[0019] Operation method: Select a suitable forming plate 3 according to the bending requirements of the aluminum tube, and install it on the support plate 2 to ensure that the forming groove 301 perfectly matches the bending shape of the aluminum tube. Place the aluminum tube to be bent at the starting position of the forming groove 301, and use the positioning hole 101 provided on the bottom plate 1 to preliminarily position the aluminum tube to ensure that the aluminum tube does not shift during the bending process. The operator manually drives the rocker arm 4 to rotate. The rotation of the rocker arm 4 drives the pressing wheel 402 to move along the track groove 201 through the guiding groove 401. During the movement, the pressing wheel 402 gradually applies pressure to the aluminum tube, guiding the aluminum tube to bend along the shape of the forming groove 301. During the bending process, the operator ensures that the bending angle and shape meet the design requirements according to the deformation of the aluminum tube, and judges the processing condition of the aluminum tube based on the force feedback of the rocker arm 4. If any abnormal situation is found, such as the aluminum tube being damaged or the bending shape being inaccurate, the operation is stopped immediately to check the reason. If necessary, adjust the position of the pressing wheel 402 or replace the suitable forming plate 3, which greatly reduces the loss during the aluminum tube processing and improves the forming rate of the product. When the aluminum tube is completely bent according to the preset shape, stop the driving device, take out the bent aluminum tube for subsequent processing or installation, realizing the efficient, precise and lossless bending of the aluminum tube, and greatly improving the production efficiency and product quality.
