[0001] The invention belongs to the technical field of air conditioners, and in particular relates to a copper tube cutting device used for processing air conditioner condensers. Background Art

[0002] In the manufacturing process of air-conditioning condensers, copper tubes are important heat transfer components, and their cutting process directly affects the accuracy and performance of the product. Since the copper tubes required for air-conditioning condensers are usually thin-walled structures, they are easily deformed or damaged by the pressure of the cutter during the cutting process, resulting in reduced processing accuracy and unstable product quality.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example:

[0041] like Figures 1 to 6As shown, a copper tube cutting device for processing an air conditioner condenser comprises: a cutting table 1, a cutting assembly 2 and a stabilizing assembly 3, wherein a guide groove 13 is provided on the upper surface of the cutting table 1 along the length direction of the cutting table 1, wherein a copper tube is placed in the guide groove 13, wherein the guide groove 13 limits the position of the copper tube to prevent the copper tube from rolling during cutting and affecting the cutting accuracy; the cutting table 1 is provided with two driving wheels 11 in the vertical direction, wherein the two driving wheels 11 are respectively arranged at the top and the bottom of the cutting table 1; a first motor 12 is arranged on the cutting table 1, wherein the output shaft of the first motor 12 is connected to the driving wheel 11; the copper tube is placed in a channel formed by the two driving wheels 11, wherein the first motor 12 drives the upper driving wheel 11 to rotate, wherein the upper driving wheel 11 drives the copper tube to slide in the guide groove 13, and the copper tube drives the lower driving wheel 11 to rotate, thereby better transporting the copper tube.

[0042] Among them, the cutting assembly 2 includes a movable seat 21, a base 22, a cutter 23 and a second motor 231. The movable seat 21 is sleeved on the outside of the cutting table 1, and the top of the base 22 is sleeved on the bottom end of the movable seat 21; a hydraulic rod 221 is vertically arranged in the base 22, and the output shaft of the hydraulic rod 221 is connected to the bottom end of the movable seat 21; the hydraulic rod 221 drives the movable seat 21 to move up and down, thereby driving the cutter 23 to move up and down to cut the copper tube.

[0043] In this embodiment, the cutter 23 and the second motor 231 are both arranged at the top of the moving seat 21, at least a portion of the cutter 23 vertically penetrates the top of the moving seat 21, the copper tube is in the moving seat 21, the lower part of the cutter 23 penetrates the moving seat 21 and is above the copper tube, the output shaft of the second motor 231 is connected to the cutter 23, and the second motor 231 drives the cutter 23 to rotate to cut the copper tube; a slag leakage groove 14 is also provided on the cutting table 1, and the slag leakage groove 14 and the cutter 23 are located in the same plane. After the cutter 23 cuts the copper tube, the cut copper slag falls out of the slag leakage groove 14 to prevent the copper slag from accumulating in the guide groove 13 and affecting the transportation of the copper tube.

[0044] like Figure 3 As shown, the stabilizing component 3 is arranged inside the moving seat 21, and the stabilizing component 3 includes a protrusion 311 and an elastic film 321; a horizontal second air groove 32 is opened on the inner wall of the top end of the moving seat 21, and the elastic film 321 is arranged in the second air groove 32; first air grooves 31 are opened on both sides of the second air groove 32, and the top end of the protrusion 311 is arranged in the first air groove 31, and the two ends of the protrusion 311 are in contact with the inner wall of the first air groove 31; the first air groove 31 and the second air groove 32 are connected through a connecting hole 33, and the connecting hole 33 is arranged at the top end of the first air groove 31; the elastic film 321 is arranged below the connecting hole 33, and the elastic film 321 is arranged between the cutter 23 and the driving wheel 11

[0045] In this embodiment, when the hydraulic rod 221 drives the movable seat 21 to move downward, the cutter 23 also moves downward to cut the copper tube. At the same time, the first gas groove 31 descends to wrap the protrusion 311. The protrusion 311 squeezes the gas in the first gas groove 31 upward through the connecting hole 33 into the second gas groove 32. The gas expands the elastic film 321 above the elastic film 321. After the elastic film 321 expands, it squeezes the upper surface of the copper tube, thereby fixing the upper surface of the cut end of the copper tube. Moreover, since the expanded elastic film 321 is pushed by gas, its pressure is relatively uniform, which avoids deformation of the copper tube, and can prevent the copper tube from vibrating during cutting and keep it stable, thereby reducing cutting damage.

[0046] like Figure 4 As shown, a liquid supply component 4 is also provided on the movable seat 21, and the liquid supply component 4 includes a pump 41, a guide pipe 42 and a dispersion pipe 43. The pump 41 is connected to the dispersion pipe 43 through the guide pipe 42, the pump 41 is connected to the movable seat 21, and the dispersion pipe 43 passes through the top of the movable seat 21; a mounting hole 44 is opened at the top of the movable seat 21, the dispersion pipe 43 passes through the movable seat 21 and extends into the movable seat 21, and the dispersion pipe 43 extends in a direction close to the cutter 23.

[0047] In this embodiment, the cutting fluid is connected to the input end of the pump 41 before use, and the cutting fluid is pumped into the interior of the guide tube 42 by the pump 41. The cutting fluid is then discharged to the cutting surface where the cutter 23 contacts the copper tube through the dispersion tube 43. The cutting fluid lubricates the cutting surface and cools the cutter 23 to prevent the copper tube from softening due to heat and reduce the cutting pressure, thereby preventing the copper tube from deforming.

[0048] like Figures 5 and 6 As shown, the end of the cutting table 1 is connected to the air supply assembly 5 through the bracket 512, and the air supply assembly 5 includes a front cover 51 and a rear cover 52, and the front cover 51 is rotatably connected to the rear cover 52; a first air duct 511 is arranged on the side of the front cover 51, and the first air duct 511 is connected to the fan 53; the rear cover 52 is connected to the front cover 51, and a second air duct 521 is arranged on the side of the rear cover 52, and a rubber tube 522 is arranged on the second air duct 521, and the rubber tube 522 is arranged in the copper tube.

[0049] In this embodiment, before cutting the copper tube, the rubber tube 522 is inserted into the copper tube, and the rear cover 52 is rotated relative to the front cover 51 so that it can adapt to the rotation of the copper tube roll during the straightening process. The fan 53 is used to pump air into the first air duct 511, so that the gas is pumped into the copper tube through the front cover 51, the rear cover 52, the second air duct 521, and the rubber tube 522 in sequence; when the copper tube is cut, the cutter 23 will block the cut end of the copper tube, resulting in an increase in the air pressure inside the copper tube, and an outwardly expanding airflow is formed on the cut surface, so that the support of the cut surface is enhanced, which can reduce the pressure of the cutter 23 on the cut surface, thereby reducing the damage and deformation of the copper tube; and because the cutter 23 and the copper tube surface are both adhered to the cutting fluid, the high-speed airflow blowing can accelerate the cooling of the cutter 23 and the copper tube, thereby avoiding heat loss. At the same time, because the elastic film 321 expands downward during cutting to shield the space on the left side of the cutter 23, the airflow movement to the right is increased, which accelerates the cooling rate of the cutter 23.

[0050] To summarize, first connect the cutting fluid and the pump 41, insert the rubber tube 522 into the copper tube, place the copper tube in the guide groove 13 and the driving wheel 11, start the first motor 12 to drive the driving wheel 11 to rotate, thereby driving the copper tube to slide in the guide groove 13; start the hydraulic rod 221, the hydraulic rod 221 drives the moving seat 21 and the cutter 23 to descend to the surface of the copper tube, start the pump 41 and the second motor 231, the second motor 231 rotates to cut the copper tube, and the pump 41 pumps the cutting fluid into the cutter 23 for lubrication and cooling; start the fan 53, the fan 53 pumps the airflow from the rubber tube 522 into the copper tube, the airflow strengthens the support of the cut surface of the copper tube, reduces the damage and deformation of the copper tube, and the cutting is completed to obtain a copper tube with a smooth cut surface.
