[0024] The structure of the bending device provided by the present utility model for the production of refrigerator and air conditioner condenser pipes is as Figure 1 and Figure 2 shown, including a workbench 1. A bending mechanism 2 is arranged on the surface of the workbench 1. The bending mechanism 2 is composed of a bending assembly 201, a fixed half-wheel 202, and a central column 203. The central column 203 is fixed on the surface of the workbench 1. The central axis of the central column 203 coincides with the central axis of the fixed half-wheel 202. The fixed half-wheel 202 is placed outside the central column 203. A bending assembly 201 is arranged on the surface of the workbench 1. A rotating frame 2011, an arc-shaped chute 2012, and a bending wheel 2013 are arranged inside the bending assembly 201. An arc-shaped chute 2012 is opened on the surface of the workbench 1. The center of the arc-shaped chute 2012 and the center of the central column 203 are on the same straight line.

The bending wheel 2013 is rotatably connected to the surface of the rotating frame 2011. The bending wheel 2013 is located on one side of the fixed half-wheel 202.

[0025] During use, the condenser pipe is inserted between the bending wheel 2013 and the fixed half-wheel 202, and then the rotating frame 2011 is rotated to make the rotating frame 2011 rotate along the arc-shaped chute 2012, so that the condenser pipe is bent 180 degrees along the fixed half-wheel 202.

[0026] Furthermore, as Figure 2 and Figure 4As shown in the figure, a positioning mechanism 3 is provided at one end of the surface of the workbench 1. The inside of the positioning mechanism 3 includes a positioning baffle 301 and a positioning component 302. A positioning component 302 is provided at one end of the surface of the workbench 1. A positioning baffle 301 is provided on the surface of the positioning component 302. Inside the positioning baffle 301, there are a slideway 3021, a reading slider 3022, a scale line 3023 and a locking bolt 3024. A slideway 3021 is fixed at one end of the surface of the workbench 1. A scale line 3023 is inlaid on the surface of the slideway 3021. A reading slider 3022 is arranged inside the slideway 3021. The reading slider 3022 is slidably matched with the slideway 3021.

[0027] During use, before bending, the positioning baffle 301 can be rotated upward so that the positioning baffle 301 does not affect the insertion of the condensate pipe into the bending mechanism 2. When one end of the condensate pipe is located inside the positioning baffle 301, the positioning baffle 301 can be lowered. Then, loosen the locking bolt 3024, and slide the reading slider 3022 so that the reading slider 3022 slides along the slideway 3021 to the specified scale line 3023. Then, tighten the locking bolt 3024 to fix the reading slider 3022. Then, pull one end of the condensate pipe to make it close to the positioning baffle 301, accurately position the position of the condensate pipe, and determine the accurate position of bending, so as to realize the position positioning function of the bending device for the condensate pipe.

[0028] Furthermore, as Figure 2 and Figure 4 shown, a replacement mechanism 4 is provided on the surface of the workbench 1. The replacement mechanism 4 is composed of an insertion block 401 and a replacement component 402. The insertion blocks 401 are respectively fixed on one side of the fixed half-wheel 202. A replacement component 402 is provided on the surface of the workbench 1. The inside of the replacement component 402 includes an insertion frame 4021, a threaded hole 4022 and a fastening stud 4023. Insertion frames 4021 are fixed on both sides of the surface of the workbench 1. The insertion frames 4021 are inserted and matched with the insertion blocks 401.

One end of the fastening stud 4023 penetrates through the insertion frame 4021 and is threadedly fastened to the threaded hole 4022.

[0029] During use, when it is necessary to replace the condenser tubes of different sizes, the fastening stud 4023 can be loosened, and then the fixed half-wheel 202 can be removed. Since the condenser tube is generally bent 180 degrees, the fixed half-wheel 202 is cylindrical. Subsequently, the fixed half-wheels 202 of different diameters are placed on one side of the central column 203, so that the fixed half-wheel 202 is sleeved on one side of the central column 203, and the insertion block 401 is inserted into the insertion frame 4021. Then, the fastening stud 4023 is tightened, and the insertion block 401 is fixed under the thread fit of the fastening stud 4023 and the threaded hole 4022, so as to realize the function that the bending device is convenient for replacing the fixed half-wheel 202.

[0030] Furthermore, as Figure 4 shown, a fixing mechanism 5 is arranged on the surface of the workbench 1. The fixing mechanism 5 is composed of a limiting plate 501 and a fixing member 502. The limiting plate 501 is fixed on the surface of the workbench 1. The limiting plate 501 is located on one side of the bending wheel 2013. The inner wall on one side of the limiting plate 501 and the inner wall of the bending wheel 2013 are in the same vertical plane. A fixing member 502 is arranged on one side of the limiting plate 501. The fixing member 502 includes a stretching spring 5021, a guiding chute 5022 and a clamping plate 5023. Guiding chutes 5022 are formed on the surface of the workbench 1. A clamping plate 5023 is arranged on one side of the limiting plate 501. The clamping plate 5023 is slidably matched with the guiding chute 5022. Stretching springs 5021 are fixed at the bottoms of the clamping plates 5023. One end of each stretching spring 5021 is fixedly connected to the inner wall of the guiding chute 5022.

[0031] During use, the clamping plate 5023 is pulled, and the condenser tube to be bent is inserted between the limiting plate 501 and the clamping plate 5023. Then, the clamping plate 5023 is released. Under the action of the stretching spring 5021, the clamping plate 5023 slides along the guiding chute 5022, and the condenser tube is quickly clamped and fixed, so as to realize the function that the bending device is convenient for fixing the condenser tube.

[0032] Working principle: During use, first, the clamping plate 5023 is pulled, and the condenser tube to be bent is inserted between the limiting plate 501 and the clamping plate 5023. Then, the clamping plate 5023 is released. Under the action of the stretching spring 5021, the clamping plate 5023 slides along the guiding chute 5022, and the condenser tube is quickly clamped and fixed, so as to realize the function that the bending device is convenient for fixing the condenser tube, thereby improving the convenience of the bending device during use.

[0033] At this time, the condenser tube is inserted between the bending wheel 2013 and the fixed half-wheel 202, and then the rotating frame 2011 is rotated, so that the rotating frame 2011 rotates along the arc-shaped chute 2012, and the condenser tube is bent 180 degrees along the fixed half-wheel 202.

[0034] Before bending, the positioning baffle 301 can be rotated upward so that the positioning baffle 301 does not affect the insertion of the condensate pipe into the bending mechanism 2. When one end of the condensate pipe is located inside the positioning baffle 301, the positioning baffle 301 can be lowered. Then, loosen the locking bolt 3024, and slide the reading slider 3022 so that the reading slider 3022 slides along the slideway 3021 to the specified scale line 3023. Then, tighten the locking bolt 3024 to fix the reading slider 3022. Then, pull one end of the condensate pipe to make it close to the positioning baffle 301, accurately position the position of the condensate pipe, and determine the accurate bending position, so as to realize the position positioning function of the bending device for the condensate pipe, thereby improving the accuracy of the bending device during use.

[0035] When it is necessary to replace condensate pipes of different sizes, the fastening stud 4023 can be loosened, and then the fixed half-wheel 202 can be removed. Since the condensate pipe is generally bent 180 degrees, the fixed half-wheel 202 is cylindrical. Then, place fixed half-wheels 202 with different diameters on one side of the central column 203, so that the fixed half-wheel 202 is sleeved on one side of the central column 203, and the insertion block 401 is inserted into the insertion frame 4021. Then, tighten the fastening stud 4023, and fix the insertion block 401 under the thread fit of the fastening stud 4023 and the threaded hole 4022, so as to realize the function of the bending device being convenient for replacing the fixed half-wheel 202, thereby improving the flexibility of the bending device during use, and finally completing the use work of the bending device.
