Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and specifically to a CNC flame cutting device and its cutting method. Background Technology

[0002] In industry, some products require flame cutting. Traditional flame cutting requires manual operation, which is both time-consuming and labor-intensive. Now, CNC control is used to control the cutting, which improves work efficiency. Therefore, a special CNC flame cutting equipment is used.

[0003] However, existing cutting equipment on the market is not convenient for limiting the cutting object during use, and the cutting position is prone to deviation. To address the above technical problems, the patent with publication number CN214054000U proposes a limiting structure on both sides to clamp and fix the iron plate when it is placed. However, when cutting from the middle, since the iron plate is only clamped and fixed from both ends, the middle position of the iron plate is suspended. As the cutting progresses, the iron plate will twist and deform, which will change the cutting trajectory and result in poor quality of the cut iron plate. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a device for cutting iron plates, thereby achieving high-quality iron plates after cutting.

[0005] The objective of this invention can be achieved through the following technical solutions: A CNC flame cutting device includes a base with a groove and a guide box fixedly installed on the base.

A second support plate is fixedly installed at the ends of the horizontal plates. Multiple sets of spaced support blocks are slidably installed on the second support plate. The support surface of the support blocks is flush with the support surface of the first support plate. A movable frame driven by a first servo module is slidably mounted on the base. A movable block driven by a second servo module is slidably mounted on the horizontal section of the movable frame. A second electric telescopic rod is fixedly mounted on the surface of the movable block near the base. A flame cutter is fixedly mounted on the output end of the second electric telescopic rod.

[0006] As a further embodiment of the present invention: a rotating plate is rotatably mounted on the first support plate, a pressure plate is slidably mounted on the rotating plate, an adjusting screw that drives the pressure plate to move up and down is threaded onto the rotating plate, and a slot for limiting the position of the rotating plate is provided in the vertical section of the first support plate.

[0007] As a further aspect of the present invention: the horizontal section of the first support plate is provided with an installation groove, a base plate is slidably installed in the installation groove, a plurality of pressure rods extending into the through groove are fixedly installed on the base plate, a plurality of springs are fixedly installed on the bottom surface of the installation groove, the movable end of the spring is fixedly connected to the base plate, the upper surface of the base plate is located outside the installation groove in the initial state, and the pressure rods abut against the horizontal plate when the base plate descends.

[0008] As a further embodiment of the present invention: a connecting chamber is fixedly installed on the horizontal plate, which is distributed along the length of the second support plate. The side of the connecting chamber near the second support plate is provided with a blowing groove for blowing air onto the surface of the second support plate. The connecting chamber is connected to an external air supply device.

[0009] As a further embodiment of the present invention: a guide plate is fixedly installed on the surface of the connecting chamber away from the base, a slider is slidably installed on the guide plate, a U-shaped limiting frame slides on the slider, the opening of the limiting frame faces the second support plate, a first electric telescopic rod that drives the limiting frame to move is fixedly installed on the slider, an operating rod is fixedly installed on the slider, and a baffle is fixedly installed on the connecting chamber.

[0010] As a further aspect of the present invention: a cleaning plate is fixedly installed at the end of the limiting frame near the second support plate, the surface of the cleaning plate near the base is flush with the upper surface of the second support plate, and the opening width of the limiting frame is greater than the width of the support block.

[0011] As a further embodiment of the present invention: a mounting plate is fixedly installed on the vertical section of the horizontal plate, a fixed plate is slidably installed on the mounting plate, and a power rod is provided on the horizontal plate for pushing the fixed plate into contact with the support block.

[0012] As a further embodiment of the present invention: the power rod is distributed along the length direction of the second support plate, the power rod is threadedly connected to the cross plate, multiple sets of power cones are fixedly installed on the power rod, and multiple sets of push plates are fixedly installed on the fixed plate, with the positions of the push plates corresponding to the power cones.

[0013] The present invention also provides a cutting method applied to the CNC flame cutting equipment described above, comprising the following steps: Step S1: Adjust the position of the two sets of first support plates according to the size of the iron plate to be cut, and then slide the horizontal plate on the first support plate according to the cutting position so that the second support plate and support block are located on both sides of the cutting line and close to the cutting line. Step S2: Move the pressure plate away from the top of the first support plate, then place the iron plate to be cut on the first support plate and the second support plate for support, and then press the iron plate firmly on the first support plate using the pressure plate. Step S3: The second electric telescopic rod drives the flame cutter to move downwards and get closer to the iron plate. The first servo module drives the moving frame to move laterally. The second servo module drives the moving block to move along a direction perpendicular to the moving frame, so that the flame cutter moves along the set trajectory to complete the cutting of the iron plate. Step S4: After cutting, release the pressure plate from the iron plate to remove the cut iron plate.

[0014] The beneficial effects of this invention are: (1) In this invention, during cutting, the first support plate, the second support plate and the support block provide overall support for the iron plate. At the same time, after the cut is made, both sides of the cut are supported by the second support plate and the support block, which ensures that the iron plate can be stably supported during cutting, avoids deformation of the iron plate due to the suspension at the cutting position during cutting, and thus changes the cutting trajectory, improves the accuracy of iron plate cutting, and ensures the quality of the iron plate after cutting.

[0015] (2) In this invention, the position near the cutting trajectory is supported by a support block. The position of the support block that needs to be adjusted is adjusted by a limiting frame so that the cutting trajectory passes between the two sets of support blocks. Therefore, there will be no obstruction below the cutting position of the iron plate during subsequent cutting, which avoids damage to the support components and avoids affecting the cutting. Even if an iron plate is cut out in the middle of the iron plate, it can be supported by multiple sets of support blocks on both sides below, ensuring stable support for the iron plate before and after cutting, and further improving the cutting quality of the iron plate.

[0016] (3) In this invention, during cutting, air blows through the air vent to the upper surface of the second support plate, so that the slag generated during cutting can be quickly cooled when it falls onto the second support plate and blown off the second support plate by the air, thus avoiding the slag from condensing on the second support plate and affecting the movement of the subsequent support blocks. When there is slag condensation on the second support plate, the slag is pushed off the second support plate by the cleaning plate, ensuring that the second support plate is always in a clean state, ensuring the smooth movement of the subsequent support blocks, and improving the convenience of the equipment.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-8As shown, the present invention is a CNC flame cutting device, including a base 1, a groove 2 on the base 1 and a guide box 3 fixedly installed on the base 1, two sets of first support plates 5 slidably installed on the base 1, a guide rod 4 for installing the first support plates 5 fixedly installed on the base 1, a pressure plate 10 provided on the first support plate 5, a rotating plate 7 rotatably installed on the first support plate 5, the pressure plate 10 slidably installed on the rotating plate 7, an adjusting screw 9 threadedly installed on the rotating plate 7 to drive the pressure plate 10 to move up and down, a slot 8 for limiting the position of the rotating plate 7 is provided on the vertical section of the first support plate 5, a plurality of horizontal plates 16 are slidably installed on the first support plate 5 through a through groove 13, a second support plate 17 is fixedly installed at the ends of the horizontal plates 16, a plurality of spaced support blocks 18 are slidably installed on the second support plate 17, and the support surface of the support block 18 is flush with the support surface of the first support plate 5; A movable frame 32 driven by a first servo module 33 is slidably mounted on the base 1. A movable block 35 driven by a second servo module 34 is slidably mounted on the horizontal section of the movable frame 32. A second electric telescopic rod 36 is fixedly mounted on the surface of the movable block 35 near the base 1. A flame cutter 6 is fixedly mounted on the output end of the second electric telescopic rod 36.

[0029] In practical application, according to the size of the iron plate to be cut, the positions of the two sets of first support plates 5 are adjusted. Then, according to the cutting position, the horizontal plate 16 is slid on the first support plate 5, so that the second support plate 17 and the support block 18 are located on both sides of the cutting line and close to the cutting line. The rotating plate 7 is rotated so that the rotating plate 7 leaves the top of the first support plate 5. Then, the iron plate to be cut can be placed on the first support plate 5 and the second support plate 17 for support. After the iron plate is placed, the rotating plate 7 is reset. At this time, one end of the rotating plate 7 enters the slot 8. The adjusting screw 9 is rotated to drive the pressure plate 10 to move downward. The pressure plate 10 presses the iron plate on the first support plate 5. After the iron plate is clamped, the first servo module 33 drives the moving frame 32 to move laterally, and the second servo module 34 drives the moving block 35 to move in a direction perpendicular to the moving frame 32, thereby adjusting the position of the flame cutter 6. The second electric telescopic rod 36 drives the flame cutter 6 to move downwards and closer to the iron plate. Then, the flame cutter 6 is turned on, and the first servo module 33 and the second servo module 34 drive the flame cutter 6 to move along the set trajectory to complete the cutting of the iron plate. The impurities generated during cutting fall downwards and enter the collection device through the guide box 3. During cutting, the first support plate 5 and the second... The support plate 17 and support block 18 provide overall support for the iron plate. After the cut is made, both sides of the cut are supported by the second support plate 17 and support block 18, which ensures that the iron plate can be stably supported during cutting. This avoids deformation of the iron plate due to suspension at the cutting position, which would lead to changes in the cutting trajectory, improves the accuracy of iron plate cutting, and ensures the quality of the cut iron plate. After cutting, the iron plate is divided into two groups. At this time, the individual iron plate is supported by the first support plate 5, the second support plate 17 and support block 18 below it. Then, the iron plate can be removed by releasing the pressure plate 10 to fix the iron plate.

[0030] Please see Figure 2 , Figure 3 , Figure 6 As shown, the present invention is a CNC flame cutting device. The horizontal section of the first support plate 5 is provided with an installation groove 11. A base plate 12 is slidably installed in the installation groove 11. Multiple sets of pressure rods 14 extending into the through groove 13 are fixedly installed on the base plate 12. Multiple sets of springs 15 are fixedly installed on the bottom surface of the installation groove 11. The movable end of the spring 15 is fixedly connected to the base plate 12. In the initial state, the upper surface of the base plate 12 is located outside the installation groove 11. When the base plate 12 descends, the pressure rods 14 abut against the horizontal plate 16.

[0031] In practical application, in the initial state, the pressure rod 14 does not contact the horizontal plate 16, and the horizontal plate 16 can move freely in the horizontal direction. When the position of the second support plate 17 is adjusted and the iron plate is placed on the first support plate 5, the second support plate 17, and the support block 18 for support, the iron plate contacts the base plate 12 and presses down on the base plate 12 until the upper surface of the base plate 12 is flush with the support surface of the first support plate 5. When the base plate 12 moves downward, it will compress the spring 15. The downward movement of the base plate 12 causes the pressure rod 14 to contact and squeeze the horizontal plate 16. Under the pressure of the iron plate, the horizontal plate 16 is fixed, thereby ensuring that the position of the second support plate 17 is fixed after the iron plate is placed, further improving the stability of the iron plate support. At the same time, after the iron plate is removed, the base plate 12 is reset upward under the action of the spring 15 to release the fixation of the horizontal plate 16, and then release the fixation of the second support plate 17, which facilitates the adjustment of the position of the second support plate 17 during subsequent use and improves the convenience of equipment use.

[0032] Please see Figure 4 , Figure 5 As shown, the present invention is a CNC flame cutting device. A connecting chamber 24 distributed along the length direction of the second support plate 17 is fixedly installed on the horizontal plate 16. The connecting chamber 24 has a blowing groove 25 for blowing towards the surface of the second support plate 17 on the side near the second support plate 17. The connecting chamber 24 is connected to an external air supply device.

[0033] Specifically, a guide plate 26 is fixedly installed on the surface of the connecting chamber 24 away from the base 1, a slider 27 is slidably installed on the guide plate 26, a U-shaped limiting frame 29 slides on the slider 27, the opening of the limiting frame 29 faces the second support plate 17, a first electric telescopic rod 28 that drives the limiting frame 29 to move is fixedly installed on the slider 27, an operating rod is fixedly installed on the slider 27, and a baffle 31 is fixedly installed on the connecting chamber 24.

[0034] Specifically, a cleaning plate 30 is fixedly installed at the end of the limiting frame 29 near the second support plate 17. The surface of the cleaning plate 30 near the base 1 is flush with the upper surface of the second support plate 17. The opening width of the limiting frame 29 is greater than the width of the support block 18.

[0035] In practical applications, when the cutting trajectory crosses the second support plate 17 or a piece of iron plate needs to be cut out from the middle of the iron plate, if the second support plate 17 completely contacts the back of the iron plate, it will cause damage to the second support plate 17 during cutting. Furthermore, the obstruction caused by the second support plate 17 will cause the iron plate to stick together after cutting. In this case, the position of the support block 18 on the second support plate 17 is adjusted according to the cutting trajectory. During adjustment, the slider 27 is moved by the operating rod so that the limiting frame 29 corresponds to the support block 18 whose position needs to be adjusted. Then, the first electric telescopic rod 28 moves the limiting frame 29 towards the support block 18 until the support block 18 enters the limiting position. Inside the frame 29, the operator can move the slider 27 again by operating the lever, which will move the corresponding support block 18 to the set position through the limit frame 29. Repeat the above operation to adjust the position of the support block 18 that needs to be adjusted through the limit frame 29, so that the cutting trajectory passes between the two sets of support blocks 18. This ensures that there will be no obstruction below the cutting position of the iron plate during subsequent cutting, avoiding damage to the support components and avoiding affecting the cutting. Even if an iron plate is cut out from the middle of the iron plate, it can be supported from below by multiple sets of support blocks 18 on both sides, ensuring stable support for the iron plate before and after cutting, and further improving the cutting quality of the iron plate. During cutting, an external air supply device delivers air into the connecting chamber 24. The air is blown onto the upper surface of the second support plate 17 through the air duct 25. This allows the molten slag generated during cutting to cool rapidly as it falls onto the second support plate 17 and is blown off by the air, preventing the molten slag from solidifying on the second support plate 17 and affecting the movement of the subsequent support block 18. When molten slag solidifies on the second support plate 17, the position of the limiting frame 29 is adjusted so that the cleaning plate 30 corresponds to the position of the molten slag. Then, the first electric telescopic rod 28 drives the limiting frame 29 to move so that the cleaning plate 30 contacts the molten slag. After that, the cleaning plate 30 pushes the molten slag off the second support plate 17, ensuring that the second support plate 17 is always in a clean state, ensuring the smooth movement of the subsequent support block 18, and improving the convenience of the equipment.

[0036] Please see Figure 4 , Figure 5 , Figure 8 As shown, the present invention is a CNC flame cutting device. A mounting plate 19 is fixedly installed on the vertical section of the horizontal plate 16. A fixing plate 20 is slidably installed on the mounting plate 19. A power rod 22 is provided on the horizontal plate 16 for pushing the fixing plate 20 into contact with the support block 18.

[0037] Specifically, the power rod 22 is distributed along the length of the second support plate 17. The power rod 22 is threadedly connected to the horizontal plate 16. Multiple sets of power cones 23 are fixedly installed on the power rod 22. Multiple sets of push plates 21 are fixedly installed on the fixed plate 20. The positions of the push plates 21 and the power cones 23 correspond.

[0038] In practical application, after the position of the support block 18 is adjusted, the power rod 22 is rotated. Since the power rod 22 is threadedly connected to the horizontal plate 16, the power rod 22 will move along the length direction of the second support plate 17. As a result, the diameter of the contact between the power cone 23 and the push plate 21 will gradually increase. Under the push of the power cone 23, the fixing plate 20 moves towards the second support plate 17. After the fixing plate 20 contacts the side of the support block 18, it presses the support block 18 onto the second support plate 17, realizing the synchronous fixing of multiple sets of support blocks 18. This prevents the support blocks 18 from moving when the iron plate is placed, further improving the stability of the iron plate support and ensuring the subsequent cutting quality. Afterward, rotating the power rod 22 in the opposite direction can relieve the pressure applied to the fixing plate 20, at which point the position of the support block 18 can be adjusted.

[0039] Please see Figures 1-4 As shown, the present invention is a cutting method applied to the aforementioned CNC flame cutting equipment, comprising the following steps: Step S1: Adjust the positions of the two sets of first support plates 5 according to the size of the iron plate to be cut, and then slide the horizontal plate 16 on the first support plate 5 according to the cutting position, so that the second support plate 17 and the support block 18 are located on both sides of the cutting line and close to the cutting line. Step S2: Move the pressure plate 10 away from the top of the first support plate 5, then place the iron plate to be cut on the first support plate 5 and the second support plate 17 for support, and then press the iron plate on the first support plate 5 by the pressure plate 10. Step S3: The second electric telescopic rod 36 drives the flame cutter 6 to move downwards and get closer to the iron plate. The first servo module 33 drives the moving frame 32 to move laterally. The second servo module 34 drives the moving block 35 to move in a direction perpendicular to the moving frame 32, so that the flame cutter 6 can move along the set trajectory to complete the cutting of the iron plate. Step S4: After cutting, release the pressure plate 10 from the iron plate to remove the cut iron plate.
