Description

Technical Field

[0001] The present invention relates to the technical field of metal profile cutting, and specifically to a metal profile cutting device. Background Art

[0002] Metal profiles such as rectangular tubes, aluminum profiles, round tubes, channel steels, and H-beams are widely used as core components for frame connections in infrastructure and mechanical equipment fields due to their generally hollow structure characteristics. Such materials are usually produced in long sizes and need to be accurately cut according to engineering requirements in actual applications to meet the adaptation requirements of different scenarios.

[0003] After retrieval, a patent document with the publication number CN118650441B discloses a metal profile cutting device, which includes a conveying plate. Two rows of guide wheels are rotatably arranged on the conveying plate, and the guide wheels are used for guiding metal profiles. A bottom plate is arranged on the side of the conveying plate. A rotating frame seat is arranged above the bottom plate. A rotating frame is rotatably arranged on the rotating frame seat. A cutting shaft is rotatably arranged on the rotating frame, and a cutting blade is arranged on the cutting shaft. The cutting blade is used for cutting metal profiles. A releasing roller is rotatably arranged below the rotating frame. A supporting seat is arranged on the bottom plate.

[0004] When the above metal profile cutting device is in use, the supporting seat is used to place the metal profile. A sliding rod is slidably arranged on the supporting seat. The two ends of the sliding rod are respectively connected to a clamping block and a releasing plate. The bottom plate is used to clamp the metal profile. The releasing plate is in contact with the releasing roller. The two ends of the first spring are respectively connected to the releasing plate and the supporting seat. The first spring provides power to drive the sliding rod to move on the supporting seat in the direction of the rotating frame seat. Therefore, the clamping block moves synchronously with the sliding rod, and the clamping block clamps the metal profile on the supporting seat to improve the cutting quality of the metal profile. However, when cutting a large number of metal profiles, the temperature of the cutting blade will become high. The high temperature causes the cutting performance of the cutting blade to degenerate and easily causes the cutting blade to be damaged.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0024] Please refer to Figures 1 to 8As shown in the figure, a metal profile cutting device includes a bottom plate 1. A cutting groove 11 is formed at the top of the bottom plate 1. Two driving rollers 2 are rotatably installed at the top of the bottom plate 1. A first mounting bracket 31 is rotatably installed on one side of the bottom 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 sleeve 33. A cutting blade 331 is rotatably installed in the inner cavity of the protective sleeve 33. A fourth motor 332 is fixedly installed on one side of the protective sleeve 33. The output shaft of the fourth motor 332 is fixedly installed on the cutting blade 331. It further includes a cooling mechanism for cooling the cutting blade 331. The cooling mechanism includes two spray water pipes 42. Both of the two spray water pipes 42 are fixedly installed on the outer surface of the protective sleeve 33. One ends of the two spray water pipes 42 are commonly fixedly connected to a pressurizing box 4. The pressurizing box 4 is fixedly installed on one side of the first mounting bracket 31. A water inlet pipe 43 is fixedly connected to the outer surface of the pressurizing box 4. One end of the water inlet pipe 43 is fixedly connected to a water tank 44. The water tank 44 is fixedly installed at the bottom of the bottom plate 1. The top of the first connecting rod 32 is fixedly connected to a second connecting rod 41. One end of the second connecting rod 41 is fixedly connected to a rubber plug 411. The rubber plug 411 is slidably installed in the inner cavity of the pressurizing box 4.

[0025] When the existing profile cutting device cuts a large number of metal profiles, the temperature of the cutting blade will become high. The high temperature causes the cutting performance of the cutting blade to degenerate and easily leads to damage of the cutting blade.

[0026] When the present invention is in use, first place the metal profile on the top of the bottom plate 1. The metal profile is located between the two driving rollers 2. The rotation of the two driving rollers 2 can drive the metal profile. When the cutting position of the metal profile moves to the bottom of the cutting blade 331, the protective sleeve 33 and the cutting blade 331 are moved downward by the first connecting rod 32. At the same time, the cutting blade 331 is rotated by the output shaft of the fourth motor 332 to realize the 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. This can make the coolant in the pressure increasing tank 4 overflow the rubber plug 411. After the cutting is completed, the first connecting rod 32 will drive the protective sleeve 33 and the second connecting rod 41 to move upward. At the same time, the second connecting rod 41 drives the rubber plug 411 to slide in the pressure increasing tank 4. When the rubber plug 411 slides upward, a negative pressure area will be formed between the bottom wall of the pressure increasing tank 4 and the bottom of the rubber plug 411. At this time, the coolant for cooling in the water tank 44 is sucked into the pressure increasing tank 4 through the water inlet pipe 43, and part of it will move upward with the rubber plug 411. Finally, it is sprayed out from both sides of the cutting blade 331 through the water spray pipe 42 to cool the cutting blade 331. Using coolant instead of water here can avoid rusting of the metal after it gets wet. A one-way valve is provided at the place where the water inlet pipe 43 is close to the pressure increasing tank 4, and the direction of the one-way valve is for the coolant to enter the pressure increasing tank 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 coolant in the closed space will squeeze the rubber plug 411, thereby deforming the rubber plug 411. The coolant 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. Therefore, the coolant can be sprayed out through the water spray pipe 42.

[0027] Further, as Figure 2 and Figure 3 shown, two first grooves 12 and two second grooves 13 are opened on the top of the bottom plate 1. The first slider 21 is slidably installed on the inner surface of the first groove 12. The two-way threaded rod 211 is rotatably installed on the inner surface of the first groove 12. The two-way threaded rod 211 is threadedly connected to the two first sliders 21; The second slider 22 is slidably installed on the inner surface of the second groove 13. The second slider 22 is fixedly installed on one side of the first slider 21. Two first gears 23 are rotatably installed at the bottom of one of the first sliders 21. The two first gears 23 mesh with each other. One of the first gears 23 and the first synchronous pulley 24 are respectively fixedly connected to the two driving rollers 2. The two driving rollers 2 are respectively rotatably installed on the tops of the two first sliders 21; A first rack 26 is slidably mounted at the bottom of the bottom plate 1. The first rack 26 meshes with a second gear 27. One side of the second gear 27 is fixedly connected with 271. One side of the bottom plate 1 is fixedly installed with a second motor 274. The output end of the second motor 274 and one end of 271 are both fixedly connected with a second synchronous pulley 272. The two second synchronous pulleys 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; A first motor 261 is fixedly installed at 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 with a first synchronous pulley 24. The three first synchronous pulleys 24 are driven by a first synchronous belt 25.

[0028] 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. Further, the two first sliders 21 drive the two driving rollers 2 to move. This move can enable the two driving rollers 2 to adjust the distance according to the width of the metal profile, so as to drive metal profiles of different models. In order to further limit the metal profile, when the two first sliders 21 move, they will respectively drive the two second sliders 22 to move. 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; The output shaft of the first motor 261 drives one of the first synchronous pulleys 24 to rotate. Through the drive of the first synchronous belt 25, the three first synchronous pulleys 24 all start to rotate. One of the first synchronous pulleys 24 drives the first gear 23 to rotate. One of the first gears 23 and the first synchronous pulley 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; Since the first synchronous belt 25 will become loose and lose the transmission effect when adjusting the distance between the two first sliders 21, in order to keep the first synchronous belt 25 always tight and capable of transmission, when the second motor 274 rotates, it will also drive the second synchronous pulley 272 to rotate. Through the drive of the second synchronous belt 273, the two second synchronous pulleys 272 all start to rotate. One of the second synchronous belts 273 drives the second gear 27 to rotate through 271. The second gear 27 can drive the first rack 26 to slide at the bottom of the bottom plate 1. When the first rack 26 slides, it will drive one of the first synchronous pulleys 24 to move, so as to achieve the purpose of keeping the first synchronous belt 25 always tight.

[0029] Further, as Figure 4As shown, a third motor 3 is fixedly installed on one side of the bottom plate 1. The output shaft of the third motor 3 is fixedly connected to one side of the first mounting frame 31. A first threaded rod 333 is rotatably installed in the inner cavity of the first mounting frame 31. A fifth motor 334 is fixedly installed on the top of the first mounting frame 31. The output shaft of the fifth motor 334 is fixedly installed on the top of the first threaded rod 333. The first threaded rod 333 is threadedly connected to the first connecting rod 32.

[0030] When the present invention is in use, the output shaft of the third motor 3 drives the first mounting frame 31 to rotate, so that the first mounting frame 31 can drive the protective sleeve 33 and the cutting blade 331 to rotate through the first connecting rod 32, thereby achieving the purpose of cutting the metal profile from an inclined plane. 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 frame 31, thereby realizing cutting the metal profile by the cutting blade 331 and moving the cutting blade 331 away from the metal profile after cutting is completed.

[0031] Further, 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 formed in 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. The sliding rods 444 are fixedly installed at the bottom of the sealing plate 442.

[0032] When the present invention is in use, when the rubber plug 411 moves upward, the coolant in the water tank 44 will enter the pressurizing 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. The coolant on the top of the sealing plate 442 will enter the bottom of the sealing plate 442 through the third groove 4421. 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 effect, the piston 443 will float again into the third groove 4421 to seal 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. The four sliding rods 444 can increase the stability of the piston 443 during sliding.

[0033] Further, as Figure 7 As shown, a limiting block 5 is fixedly installed on one side of the first connecting rod 32. A second mounting frame 51 is rotatably installed in the inner cavity of the limiting block 5. A first telescopic rod 52 is rotatably installed on the top of the second mounting frame 51. The first telescopic rod 52 is rotatably installed on one side of the first connecting rod 32. Two second telescopic rods 53 are fixedly installed at the bottom of the second mounting frame 51. The output ends of the two second telescopic rods 53 are jointly rotatably connected to a limiting roller 54.

[0034] When the present invention is in use, in order to prevent the metal profile on the other side of the cutting disc 331 from shifting during the cutting of the metal profile, the metal profile is fixed by the limiting roller 54. When the cutting disc 331 obliquely cuts the metal profile, the first connecting rod 32 will drive the second mounting bracket 51 to rotate. At this time, the first telescopic rod 52 supports the second mounting bracket 51, and the two second telescopic rods 53 enable the limiting roller 54 to apply pressure to the metal profile.

[0035] Further, as Figure 8 shown, a second rack 6 is fixedly connected to one side of the first connecting rod 32. The second rack 6 meshes with a third gear 61. The third gear 61 is rotatably mounted on one side of the first mounting bracket 31. A third synchronous wheel 62 is fixedly connected to one side of the third gear 61. A push plate 66 is slidably mounted on the top of the bottom plate 1. A second threaded rod 64 is threadedly connected to one side of the push plate 66 and is slidably connected to a limiting rod 65. A fixing frame 67 is fixedly connected to the top of the bottom plate 1. The second threaded rod 64 is rotatably mounted on one side of the fixing frame 67. The limiting rod 65 is fixedly mounted on one side of the fixing frame 67; Third synchronous wheels 62 are fixedly mounted on one side of both the third gear 61 and the second threaded rod 64. The two third synchronous wheels 62 are driven by a third synchronous belt 63.

[0036] When the present invention is in use, in order to prevent the cut metal profile from affecting the subsequent metal profile, after cutting is completed, the first connecting rod 32 first drives the cutting disc 331 to move upward. At this time, the first connecting rod 32 drives the second rack 6 to move. The second rack 6 drives the third gear 61 to rotate and is transmitted through the third synchronous belt 63. Another third synchronous wheel 62 drives the second threaded rod 64 to rotate and cooperates with the limiting 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 then drives the second rack 6 to move upward, thereby driving the third synchronous wheel 62 to drive the second threaded rod 64 to rotate. 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 reverse direction to make the push plate 66 return to the initial position, thereby realizing reciprocating pushing of the metal profile.

[0037] Working principle: First, place the metal profile on the top of the bottom plate 1. According to the width of the metal profile, adjust the distance between the two driving rollers 2. The output shaft of the second motor 274 drives the bidirectional threaded rod 211 to rotate. 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 pulley 272 to rotate and is transmitted through the second synchronous belt 273. Another second synchronous pulley 272 drives 271 and the second gear 27 to rotate. The second gear 27 drives the first rack 26 to move, thereby changing the position of the first motor 261. This can keep the first synchronous belt 25 always tight and can always drive the three first synchronous pulleys 24. Through the transmission of the two first gears 23, the two driving rollers 2 can rotate synchronously and 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 threaded rod 333 to rotate, driving the first connecting rod 32 to move downward, and then the protective sleeve 33 and the cutting blade 331 also move downward, so that the cutting blade 331 cuts the metal profile. When the first connecting rod 32 moves downward, the first connecting rod 32 drives the second connecting rod 41 and the rubber plug 411 to move downward. 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 cutting is completed, the first connecting rod 32 drives the cutting blade 331 to move upward. At the same time, the first connecting rod 32 drives the rubber plug 411 to move upward through the second connecting rod 41. At this time, the coolant at the top of the rubber plug 411 will be sprayed onto the cutting blade 331 through the water spray pipe 42 to cool the 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 onto the cutting blade 331 from the water spray pipe 42 to cool the cutting blade 331.

[0038] During use, when the first connecting rod 32 moves up and down, the first connecting rod 32 will drive the second rack 6 to move. The second rack 6 can drive the third gear 61 to rotate. The second rack 6 drives one of the third synchronous pulleys 62 through the third synchronous belt 63. Another third synchronous pulley 62 can drive the second threaded rod 64 to rotate. Under the limitation of the limiting rod 65, the second threaded rod 64 can drive the push plate 66 to slide along the limiting rod 65, thereby pushing out the cut metal profile and preventing the cut metal profile from affecting subsequent cutting work.
