Detailed Embodiment

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figure 1 、 Figure 3 and Figure 4 , an embodiment provided by the present utility model: a heat exchanger fin cutting device, including a hollow frame 1. A U-shaped plate 3 is connected to the top of the hollow frame 1. A fixed frame 4 is connected to the right end of the outside of the U-shaped plate 3. A water pump 5 is connected to the top of the fixed frame 4. One end of the water pump 5 is communicated with a connecting pipe 6, and the other end of the water pump 5 is communicated with a curved pipe 7. The bottom end of the curved pipe 7 penetrates the hollow frame 1. The bottom ends of the connecting pipe 6 and the curved pipe 7 are both communicated with a water outlet pipe 8. The middle and lower part of the water outlet pipe 8 penetrates the fixed frame 4 and is communicated with a spray head 9. A filter screen frame 10 is slidably connected inside the hollow frame 1. An opening groove 11 is opened at the inner bottom of the U-shaped plate 3. A bidirectional lead screw 12 is rotatably connected to the front side of the U-shaped plate 3. The rear end of the bidirectional lead screw 12 penetrates the opening groove 11. Clamping plates 13 are threadedly connected to the front and rear sides of the outer wall of the bidirectional lead screw 12. The bottoms of the two clamping plates 13 are both slidably connected to the inside of the opening groove 11. A disassembly mechanism 2 is arranged inside the fixed frame 4. The disassembly mechanism 2 is used to facilitate the disassembly and replacement of damaged cutting tools. A handle 20 is connected to the middle of the right side of the filter screen frame 10. The size of the filter screen frame 10 is the same as the internal size of the hollow frame 1. The middle of the bottom end on the left side of the hollow frame 1 is communicated with a water outlet 16. A one-way valve 17 is arranged outside the water outlet 16.

[0034] Specifically, when the bidirectional lead screw 12 is rotated, the clamping plates 13 on its outside will move towards the middle along the inside of the opening groove 11 until they are in close contact with the front and rear sides of the heat exchanger fins. This process can effectively prevent unnecessary shaking of the heat exchanger fins during processing. Subsequently, the hydraulic rod 201 can drive the blade 211 to move up and down to precisely cut the heat exchanger fins. At the same time, the water pump 5 can suck the water source in the hollow frame 1 and send it into the inlet and outlet water pipe 8, and then spray the water through the spray head 9 onto the working blade 211 to achieve the cooling treatment of the blade 211. The water source after the cooling treatment will flow into the hollow frame 1 through the groove 22, and the impurities in the water source will be intercepted by the filter screen frame 10 and remain on the filter screen frame 10. The water source filtered by the filter screen frame 10 will directly flow into the bottom inside the hollow frame 1. At this time, the one-way valve 17 is opened, and the water source inside the hollow frame 1 will be discharged through the water outlet 16, thereby realizing the recycling of the used water source.

[0035] Referring toFigure 1 , Figure 5 and Figure 6 , the disassembly mechanism 2 includes a hydraulic rod 201, the hydraulic rod 201 is connected to the inner top of the fixed frame 4, one end of the hydraulic rod 201 is connected with a fixed column 202, a hollow column 206 is arranged on the outer side of the fixed column 202, holes 203 are formed on both the front and rear sides of the fixed column 202, one side inside the hole 203 is connected with a spring 204, one end of the spring 204 is connected with a limiting rod 205, limiting holes 207 are formed on both the front and rear sides of the hollow column 206, and the two limiting rods 205 are respectively inserted into the corresponding limiting holes 207. Fixed strips 208 are connected to both the front and rear sides of the hydraulic rod 201, a T-shaped rod 209 is slidably connected inside the fixed strip 208, a push rod 210 is connected to the adjacent side of the two T-shaped rods 209, and a blade 211 is connected to the bottom end of the hollow column 206;

[0036] Specifically, slowly move the two T-shaped rods 209 towards the middle until the push rod 210 is in close contact with the limiting rod 205. During this process, the spring 204 will be subjected to a squeezing force, which will cause the limiting rod 205 to disengage from the original limiting hole 207. As the limiting rod 205 moves, it will smoothly enter the hole 203. At this time, the limiting and fixing of the hollow column 206 can be released, and the work of disassembling and replacing the blade 211 is relatively simple.

[0037] Refer to Figure 1 , Figure 2 and Figure 3 , the upper middle part of the front side of the hollow frame 1 is connected with a control panel 15, and the control panel 15 is electrically connected to the water pump 5 and the hydraulic rod 201 respectively;

[0038] Specifically, the work of the water pump 5 and the hydraulic rod 201 can be controlled through the control panel 15. The model of the water pump 5 can be IS50-32-125, and the model of the hydraulic rod 201 can be P1D-S050MS-0200.

[0039] Refer to Figure 1 , Figure 2 and Figure 3 , rubber pads 14 are connected to the adjacent sides of the two clamping plates 13, the sizes of the two rubber pads 14 are respectively the same as the sizes of the corresponding clamping plates 13, a fixing belt 18 is arranged on the outer wall of the curved pipe 7, bolts 19 are threadedly connected to the left and right sides of the two fixing belts 18, and the rear ends of the multiple bolts 19 respectively penetrate through the fixing belt 18 and the hollow frame 1 in sequence;

[0040] Specifically, the rubber pads 14 can further increase the friction between the clamping plates 13 and the heat exchanger fins, so that it can be placed more stably, and the arranged fixing belt 18 can limit and fix the curved pipe 7, so that it can be placed more stably.

[0041] Referring to Figure 1 , a groove 22 is provided on the right side of the inner bottom end of the U-shaped plate 3, and a stop block 21 is connected to the right end of the inner bottom of the U-shaped plate 3;

[0042] Specifically, the groove 22 can facilitate the processing of the heat exchanger fins, and the provided stop block 21 can prevent water leakage.

[0043] When using this device, first pull out the filter screen frame 10 through the handle 20, then inject cooling water into the hollow frame 1 through the groove 22. After the cooling water reaches a certain height, put the filter screen frame 10 back, and then place the heat exchanger fins to be processed on the U-shaped plate 3. Then rotate the bidirectional lead screw 12, and the clamping plates 13 on its outer side will move towards the middle inside the opening groove 11 until they contact the front and back sides of the heat exchanger fins, which can prevent the heat exchanger fins from shaking during processing and affecting the processing accuracy. Then, the hydraulic rod 201 can drive the blade 211 to move up and down to cut the heat exchanger fins. At the same time, the water pump 5 can pump the water in the hollow frame 1 into the water outlet pipe 8, and then spray it onto the blade 211 through the nozzle 9 to cool the working blade 211. The cooled water will flow into the hollow frame 1 through the groove 22, and the impurities in the water will be blocked by the filter screen frame 10 and remain on the filter screen frame 10. The filtered water will directly flow into the inner bottom of the hollow frame 1. At this time, open the one-way valve 17, and the water inside the hollow frame will be discharged through the water outlet 16, which can recycle the used water;

[0044] And when the blade 211 is prone to damage after long-term use and needs to be replaced, at this time, move the two T-shaped rods 209 towards the middle until the push rod 210 contacts the limiting rod 205. At this time, the force exerted by the spring 204 being compressed will drive the limiting rod 205 to disengage from the limiting hole 207 and enter the hole 203, which can release the limiting fixation of the hollow column 206, and it is relatively simple to disassemble and replace the blade 211.

[0045] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
