[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figures 1 to 8As shown, a metal profile cutting device includes a base plate 1, a cutting groove 11 is opened on the top of the base plate 1, two driving rollers 2 are rotatably installed on the top of the base plate 1, a first mounting bracket 31 is rotatably installed on one side of the base plate 1, a first connecting rod 32 is slidably installed in the inner cavity of the first mounting bracket 31, one end of the first connecting rod 32 is fixedly connected to a protective cover 33, a cutting blade 331 is rotatably installed in the inner cavity of the protective cover 33, a fourth motor 332 is fixedly installed on one side of the protective cover 33, and the output shaft of the fourth motor 332 is fixedly installed on the cutting blade 331; a cooling mechanism is also included for cooling the cutting blade 331; the cooling mechanism The structure includes two water spray pipes 42, and the two water spray pipes 42 are fixedly mounted on the outer surface of the protective cover 33. One end of the two water spray pipes 42 is commonly fixedly connected to the boost box 4, and the boost box 4 is fixedly mounted on one side of the first mounting frame 31. The outer surface of the boost box 4 is fixedly connected to a water inlet pipe 43, and one end of the water inlet pipe 43 is fixedly connected to a water tank 44. The water tank 44 is fixedly mounted on the bottom of the base plate 1. The top of the first connecting rod 32 is fixedly connected to the second connecting rod 41, and one end of the second connecting rod 41 is fixedly connected to a rubber plug 411. The rubber plug 411 is slidably mounted in the inner cavity of the boost box 4, and the inner cavity of the boost box 4 is coolant.

[0035] When existing profile cutting devices are used to cut a large number of metal profiles, the temperature of the cutting blade will become high. The high temperature will cause the cutting performance of the cutting blade to degrade and may also easily cause damage to the cutting blade.

[0036] When the present invention is in use, the metal profile is first placed on the top of the bottom plate 1, and the metal profile is between the two driving rollers 2. The two driving rollers 2 rotate to drive the metal profile. When the cutting position of the metal profile moves to the bottom of the cutting blade 331, the first connecting rod 32 drives the protective cover 33 and the cutting blade 331 to move downward, and at the same time, the output shaft of the fourth motor 332 drives the cutting blade 331 to rotate to achieve cutting of the metal profile. At the same time, the rubber plug 411 also drives the second connecting rod 41 to move downward through the first connecting rod 32, which enables the coolant in the inner cavity of the booster box 4 to overflow the rubber plug 411. After the cutting is completed, the first connecting rod 32 will move upward with the protective cover 33 and the second connecting rod 41, and at the same time, the second connecting rod 41 drives the rubber plug 411 to slide in the inner cavity of the booster box 4. When the rubber plug 411 slides upward, a negative pressure area will be formed between the bottom wall of the booster box 4 and the bottom of the rubber plug 411. At this time, the water tank 4 The cooling liquid in the inner cavity of the 4 is sucked into the inner cavity of the booster box 4 through the water inlet pipe 43, and part of it moves upward with the rubber plug 411, and is finally sprayed out from both sides of the cutting blade 331 through the water spray pipe 42 to cool the cutting blade 331. Using cooling liquid instead of water here can prevent the metal from rusting after being exposed to water. A one-way valve is provided near the booster box 4 with the water inlet pipe 43, and the direction of the one-way valve is that the cooling liquid enters the inner cavity of the booster box 4 through 43. When the rubber plug 411 moves downward, a closed space is formed between the one-way valve in the water inlet pipe 43 and the rubber plug 411. The cooling liquid in the closed space will squeeze the rubber plug 411, thereby deforming the rubber plug 411, and the cooling liquid will pass through the rubber plug 411 and enter the upper part of the rubber plug 411. When the rubber plug 411 moves upward, since there is no pressure on the top of the rubber plug 411, the rubber plug 411 will not be deformed at this time, thereby enabling the cooling liquid to be sprayed out through the water spray pipe 42.

[0037] Further, such as Figure 2 and Figure 3 As shown, the top of the base plate 1 is provided with two first grooves 12 and two second grooves 13. A first slider 21 is slidably mounted on the inner surface of the first groove 12. A bidirectional threaded rod 211 is rotatably mounted on the inner surface of the first groove 12. The bidirectional threaded rod 211 is threadedly connected to the two first sliders 21.

[0038] A second slider 22 is slidably mounted on the inner surface of the second groove 13. The second slider 22 is fixedly mounted on one side of the first slider 21. Two first gears 23 are rotatably mounted on the bottom of one of the first sliders 21. The two first gears 23 are meshed with each other. One of the first gears 23 and the first synchronous wheel 24 are respectively fixedly connected to two driving rollers 2. The two driving rollers 2 are respectively rotatably mounted on the top of the two first sliders 21.

[0039] A first rack 26 is slidably mounted on the bottom of the base plate 1. The first rack 26 is meshed with a second gear 27. One side of the second gear 27 is fixedly connected to a connecting shaft 271. A second motor 274 is fixedly mounted on one side of the base plate 1. The output end of the second motor 274 and one end of the connecting shaft 271 are both fixedly connected to a second synchronous gear 272. The two second synchronous gears 272 are driven by a second synchronous belt 273. One end of the bidirectional threaded rod 211 is fixedly connected to the output shaft of the second motor 274.

[0040] A first motor 261 is fixedly mounted on the bottom of the first rack 26 . The first gear 23 , the first slider 21 and the output shaft of the first motor 261 are all fixedly connected to first synchronous wheels 24 . The three first synchronous wheels 24 are driven by a first synchronous belt 25 .

[0041] When the present invention is in use, the output shaft of the second motor 274 drives the bidirectional threaded rod 211 to rotate, so that the bidirectional threaded rod 211 can drive the two first sliders 21 to slide on the inner surfaces of the two first grooves 12 respectively, and then the two first sliders 21 move with the two driving rollers 2. This allows the two driving rollers 2 to adjust the distance according to the width of the metal profile, thereby achieving the driving of metal profiles of different models. In order to further achieve the limitation of the metal profile, when the two first sliders 21 move, they will respectively move the two second sliders 22. The two second sliders 22 slide on the inner surfaces of the two second grooves 13 respectively. The two second sliders 22 can limit the metal profile again to prevent the metal profile from shifting during cutting;

[0042] The output shaft of the first motor 261 drives one of the first synchronous wheels 24 to rotate, and the three first synchronous wheels 24 are driven by the first synchronous belt 25 to start rotating. One of the first synchronous wheels 24 drives the first gear 23 to rotate, and one of the first gears 23 and the first synchronous wheel 24 can drive the driving roller 2 to rotate. The two driving rollers 2 rub against the outer surface of the metal profile to achieve the purpose of driving the metal profile to move.

[0043] Since the first synchronous belt 25 will become loose and lose the transmission effect when the distance between the two first sliders 21 is adjusted, in order to keep the first synchronous belt 25 taut and able to transmit, the second synchronous wheel 272 will also rotate when the second motor 274 rotates. After the second synchronous belt 273 drives the two second synchronous wheels 272 to start rotating, one of the second synchronous belts 273 rotates with the second gear 27 through the connecting shaft 271. The second gear 27 can drive the first rack 26 to slide on the bottom of the base plate 1. When the first rack 26 slides, it will move one of the first synchronous wheels 24, thereby achieving the purpose of keeping the first synchronous belt 25 taut.

[0044] Further, such as Figure 4As shown, a third motor 3 is fixedly mounted on one side of the base plate 1, and the output shaft of the third motor 3 is fixedly connected to one side of the first mounting bracket 31. A first threaded rod 333 is rotatably mounted in the inner cavity of the first mounting bracket 31, and a fifth motor 334 is fixedly mounted on the top of the first mounting bracket 31. The output shaft of the fifth motor 334 is fixedly mounted on the top of the first threaded rod 333, and the first threaded rod 333 is threadedly connected to the first connecting rod 32.

[0045] When the present invention is in use, the output shaft of the third motor 3 drives the first mounting bracket 31 to rotate, so that the first mounting bracket 31 can rotate with the protective cover 33 and the cutting blade 331 through the first connecting rod 32, thereby achieving the purpose of cutting the metal profile from the oblique surface. When in use, the output shaft of the fifth motor 334 drives the first threaded rod 333 to rotate, and the first threaded rod 333 can drive the first connecting rod 32 to slide along the inner cavity of the first mounting bracket 31, thereby achieving the purpose of making the cutting blade 331 cut the metal profile and move the cutting blade 331 away from the metal profile after cutting is completed.

[0046] Further, such as Figure 6 As shown, a filter plate 441 and a sealing plate 442 are fixedly installed in the inner cavity of the water tank 44, a third groove 4421 is opened on the top of the sealing plate 442, a piston 443 is slidably installed on the inner surface of the third groove 4421, four sliding rods 444 are slidably installed on the outer surface of the piston 443, and the sliding rods 444 are fixedly installed at the bottom of the sealing plate 442.

[0047] When the present invention is in use, when the rubber stopper 411 moves upward, the coolant in the water tank 44 will enter the inner cavity of the booster tank 4 through the water inlet pipe 43. At this time, the bottom of the water tank 44 will be in a negative pressure state, and the coolant at the top of the sealing plate 442 will pass through the third groove 4421 and enter the bottom of the sealing plate 442. During this process, the piston 443 will be pushed downward by the coolant. After the bottom of the sealing plate 442 is filled with coolant, due to the buoyancy, the piston 443 will float to the third groove 4421 again, thereby sealing the bottom of the sealing plate 442. This can protect the coolant at the bottom of the sealing plate 442 when the coolant on the top of the sealing plate 442 is contaminated, and the stability of the piston 443 during sliding can be increased by the four sliding rods 444.

[0048] Further, such as Figure 7 As shown, a limit block 5 is fixedly installed on one side of the first connecting rod 32, and a second mounting bracket 51 is rotatably installed in the inner cavity of the limit block 5. A first telescopic rod 52 is rotatably installed on the top of the second mounting bracket 51. The first telescopic rod 52 is rotatably installed on one side of the first connecting rod 32, and two second telescopic rods 53 are fixedly installed on the bottom of the second mounting bracket 51. The output ends of the two second telescopic rods 53 are rotatably connected to a limit roller 54.

[0049] When the present invention is in use, in order to prevent the metal profile on the other side of the cutting blade 331 from shifting when cutting the metal profile, the metal profile is fixed by a limiting roller 54. When the cutting blade 331 is tilted to cut the metal profile, the first connecting rod 32 will rotate with the second mounting frame 51. At this time, the first telescopic rod 52 supports the second mounting frame 51, and the two second telescopic rods 53 can enable the limiting roller 54 to exert pressure on the metal profile.

[0050] Further, such as Figure 8 As shown, one side of the first connecting rod 32 is fixedly connected to the second rack 6, the second rack 6 is meshed with a third gear 61, the third gear 61 is rotatably mounted on one side of the first mounting bracket 31, one side of the third gear 61 is fixedly connected to a third synchronous wheel 62, a push plate 66 is slidably mounted on the top of the base plate 1, one side of the push plate 66 is threadedly connected to a second threaded rod 64 and is slidably connected to a limit rod 65, the top of the base plate 1 is fixedly connected to a fixing bracket 67, the second threaded rod 64 is rotatably mounted on one side of the fixing bracket 67, and the limit rod 65 is fixedly mounted on one side of the fixing bracket 67;

[0051] A third synchronous wheel 62 is fixedly mounted on one side of the third gear 61 and the second threaded rod 64 , and the two third synchronous wheels 62 are driven by a third synchronous belt 63 .

[0052] When the present invention is in use, in order to prevent the cut metal profile from affecting the following metal profile, after the cutting is completed, the first connecting rod 32 first moves upward with the cutting blade 331, and at this time the first connecting rod 32 moves with the second rack 6, and the second rack 6 drives the third gear 61 to rotate through the third synchronous belt 63, and another third synchronous wheel 62 drives the second threaded rod 64 to rotate and cooperate with the limit rod 65 to drive the push plate 66 to slide. At this time, the push plate 66 approaches the metal profile. At this time, the new metal profile pushes the cut metal profile to move. When the cut metal profile is pushed to one side of the push plate 66, the first connecting rod 32 moves upward with the second rack 6, and then drives the third synchronous wheel 62 to rotate with the second threaded rod 64, and the second threaded rod 64 drives the push plate 66 to push the metal profile. Then the first connecting rod 32 moves downward, and the second threaded rod 64 rotates in the opposite direction and then returns the push plate 66 to the initial position, thereby realizing reciprocating pushing of the metal profile.

[0053] Working principle: First, place the metal profile on the top of the base plate 1, and adjust the distance between the two driving rollers 2 according to the width of the metal profile. The output shaft of the second motor 274 drives the bidirectional threaded rod 211 to rotate, and the bidirectional threaded rod 211 drives the two driving rollers 2 to move synchronously. At the same time, the output shaft of the second motor 274 drives the second synchronous wheel 272 to rotate through the second synchronous belt 273. The other second synchronous wheel 272 drives the connecting shaft 271 and the second gear 27 to rotate. The second gear 27 drives the first rack 26 to move and thus change the position of the first motor 261. This can keep the first synchronous belt 25 taut and can always drive the three first synchronous wheels 24. The two first gears 23 can make the two driving rollers 2 rotate synchronously in opposite directions, thereby realizing the transmission of the metal profile. After the metal profile moves to the bottom of the cutting blade 331, the output shaft of the fifth motor 334 drives the first The threaded rod 333 rotates to drive the first connecting rod 32 to move downward, thereby causing the protective sleeve 33 and the cutting blade 331 to move downward as well, so that the cutting blade 331 cuts the metal profile. When the first connecting rod 32 moves downward, the first connecting rod 32 moves downward with the second connecting rod 41 and the rubber plug 411. At this time, the coolant at the bottom of the rubber plug 411 will pass through the rubber plug 411 to the top of the rubber plug 411. After the cutting is completed, the first connecting rod 32 moves upward with the cutting blade 331. At the same time, the first connecting rod 32 moves upward with the rubber plug 411 through the second connecting rod 41. At this time, the coolant at the top of the rubber plug 411 will be sprayed toward the cutting blade 331 through the water spray pipe 42 to cool 311. When the first connecting rod 32 moves downward, the coolant at the bottom of the rubber plug 411 enters the top of the rubber plug 411, waiting to be sprayed from the water spray pipe 42 to the cutting blade 331 to cool the cutting blade 331.

[0054] During use, when the first connecting rod 32 moves up and down, the first connecting rod 32 will move with the second rack 6, and the second rack 6 can drive the third gear 61 to rotate. The second rack 6 drives one of the third synchronous wheels 62 through the third synchronous belt 63, and the other third synchronous wheel 62 can rotate with the second threaded rod 64. Under the limit of the limit rod 65, the second threaded rod 64 can drive the push plate 66 to slide along the limit rod 65, thereby pushing out the cut metal profile to prevent the cut metal profile from affecting the subsequent cutting work.
