Description

Technical Field

[0001] The utility model relates to the technical field of condenser tube processing, in particular to a refrigerator condenser tube forming device. Background Art

[0002] The condenser tubes in a refrigerator are used to cool the high-temperature, high-pressure refrigerant gas discharged from the compressor and convert it into liquid, thereby transferring and dissipating heat. Typically, these tubes are arranged in a U-shaped, end-to-end series configuration. This allows for more efficient use of limited space, allowing the tubes to extend their length within a limited volume, thereby increasing the heat dissipation area and improving heat exchange efficiency.

[0003] like Figure 4 As shown, the pipe fitting 3 is initially in the state shown at the top of the figure, which is a straight pipe. Then, it is bent at one side of the outer periphery of the pipe fitting 3, that is, point B, so that the pipe fitting 3 is in the state shown in the middle of the figure, and a U-shaped structure appears. Next, it is bent at the other side of the outer periphery of the pipe fitting, that is, point C, so that the pipe fitting 3 is in the state shown at the bottom of the figure, with two bent portions. Similarly, in order for the pipe fitting 3 to be formed into the final condenser, it is necessary to start from one end thereof, along the axial direction, and alternately perform multiple bends on both sides of the outer periphery of the pipe fitting 3.

[0004] The existing technology uses a method of manually measuring the bending position and manually bending the pipe 3, which is time-consuming and labor-intensive, and it is difficult to stably control the pipe 3 and accurately control the bending point, resulting in poor consistency of the condenser tubes finally produced.
