DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Such as Figure 1-2 , Figure 4As shown in the figure, a cutting device for metal doors and windows production includes a cutting table main body 1; a cutting machine 104 is installed on the top of the cutting table main body 1; a servo motor 11 is fixedly connected to one side of the bottom of the cutting table main body 1; the output end of the servo motor 11 is rotationally connected to a belt 12; a roller 13 is rotationally connected inside the cutting table main body 1; a roller 14 is fixedly connected to the outside of the roller 13; one end of the roller 13 close to the belt 12 is rotationally connected to the belt 12; a first belt groove fixing block 15 is fixedly connected to one side of the top of the cutting table main body 1 close to the belt 12; a second belt groove fixing block 16 is fixedly connected to one side of the top of the cutting table main body 1 close to the first belt groove fixing block 15; a return spring 17 is fixedly connected inside the first belt groove fixing block 15; a sliding slider 18 is fixedly connected to the top of the return spring 17; the sliding slider 18 is slidably connected inside the first belt groove fixing block 15; a threaded column 100 is rotationally connected inside the second belt groove fixing block 16; a threaded slider 101 is threadedly connected to the outside of the threaded column 100; the threaded slider 101 is slidably connected inside the second belt groove fixing block 16; pressing strips 19 are fixedly connected to both sides of the threaded slider 101; the pressing strips 19 are placed on the top of the sliding slider 18; a rotating handle 102 is fixedly connected to the top of the threaded column 100; a pressing plate 103 is fixedly connected to one side of the threaded slider 101 away from the second belt groove fixing block 16; a pressing plate 103 is fixedly connected to one side of the sliding slider 18 away from the first belt groove fixing block 15; during operation, the workpiece is placed above the roller 14, then the rotating handle 102 is toggled to drive 110 to start rotating, so that the threaded slider 101 descends inside the second belt groove fixing block 16, driving the pressing strips 19 to start descending inside multiple first belt groove fixing blocks 15, squeezing multiple sliding sliders 18, and then the sliding sliders 18 squeeze the return spring 17, causing the return spring 17 to start deforming. Since pressing plates 103 are fixedly connected to one ends of the sliding slider 18 and the threaded slider 101, the pressing plates 103 are driven to squeeze the workpiece above the roller 14, and at the same time, the cutting machine 104 is pulled down to reach a suitable position to cut the workpiece. Then, the servo motor 11 is driven to drive the belt 12 to start rotating, realizing that the roller 13 drives the roller 14 to start rotating. Through the rotation of the roller 14, the workpiece is moved closer to the cutting machine 104 to achieve the purpose of cutting. In this step, when cutting metal doors and windows, at the beginning of cutting, a large impact force is easily generated directly between the workpiece and the cutting machine 104. Coupled with the uneven feeding speed, the cutting effect is poor, and it may even lead to breakage. Therefore, at the beginning of cutting the workpiece, the pressing plate 103 descends to squeeze the upper part of the workpiece, making the workpiece closely adhere to the roller 14, increasing the stability of the workpiece. At the same time, the rotation of the roller 14 will achieve the effect of slow feeding, greatly reducing the possibility of breakage between the workpiece and the cutting machine 104. At the same time, after the cutting machine 104 cuts out the guide groove, other feeding methods can be used to increase the cutting efficiency of the workpiece.

[0024] AsFigure 1 、 Figure 3 As shown, a support column 2 is fixedly connected to the top of the cutting table body 1 near the cutting machine 104; a slide groove 24 is provided inside the support column 2; a limiting hole 22 is provided on one side inside the slide groove 24; a limiting slider 25 is slidably connected inside the support column 2; a spring limiting button 23 is fixedly connected to one end of the limiting slider 25; a spring limiting button 23 is slidably connected inside the limiting hole 22; an iron chip collection box 21 is fixedly connected to one end of the limiting slider 25; an iron chip collection box 21 is slidably connected to one side outside the support column 2; an opening and closing plate 26 is installed at the bottom of the iron chip collection box 21; when working, first press the spring limiting button 23 to install the limiting slider 25 inside the slide groove 24, and then release the spring limiting button 23, the spring limiting button 23 will automatically align with the limiting hole 22, limit the limiting slider 25, and realize The effect of installing the iron chip collection box 21 on one side of the support column 2, and then adjusting the height of the iron chip collection box 21 by the cooperation of the spring limit button 23 and the limit hole 22, and adjusting it to different heights according to the thickness of the workpiece. When cutting the workpiece, because it is made of metal, a large amount of sparks and metal debris will be generated during the cutting process. These debris and sparks will fly everywhere and pollute the working environment and cause damage to the workers. Therefore, the iron chip collection box 21 is used to block and collect the flying debris, reducing the pollution of the working environment caused by the flying debris. Adjusting the height of the iron chip collection box 21 can make the iron chip collection box 21 in a suitable position, and enhance the efficiency of debris collection. When too much debris is accumulated, the debris inside the iron chip collection box 21 can be removed by opening the opening and closing plate 26 for unified treatment.

[0025] If Figure 1 、 Figure 3 As shown in the figure, the iron chip collection box 21 is provided with an arc-shaped sliding groove 3 on the side away from the support column 2; a cleaning cylinder 32 is slidably connected inside the arc-shaped sliding groove 3; a plugging strip 31 is installed inside the arc-shaped sliding groove 3; a limited sliding groove 33 is provided on the side away from the arc-shaped sliding groove 3 inside the iron chip collection box 21; a cleaning cylinder 32 is slidably connected inside the limited sliding groove 3; after work, the plugging strip 31 installed inside the arc-shaped sliding groove 3 is removed, and then the cleaning cylinder 32 is moved to slide inside the arc-shaped sliding groove 3 and the limited sliding groove 33, so as to achieve the effect of cleaning the side wall of the iron chip collection box 21. After cleaning, the plugging strip 31 is installed inside the arc-shaped sliding groove 3. In this step, when collecting the splashed debris, some debris may be adsorbed on the side wall of the cutting table body 1, which is not easy to clean. Long-term accumulation may reduce the service life of the iron chip collection box 21. Therefore, the cleaning cylinder 32 is used to clean the inside of the iron chip collection box 21, thereby increasing the service life of the iron chip collection box 21.

[0026] If Figure 1 、​​Figure 4 As shown in the figure, a fixing plate 4 is fixedly connected to the top of the cutting table body 1 near one side of the cutting machine 104; a telescopic rod 41 is fixedly connected to the side of the fixing plate 4 away from the cutting machine 104; a limiting plate 42 is fixedly connected to the telescopic end of the telescopic rod 41; when working, when the workpiece is placed above the roller 14, the telescopic rod 41 is driven to start telescoping, so that it drives the limiting plate 42 to extrude the workpiece from the side. In this step, when cutting the workpiece, some special requirements may result in less cutting amount on one side of the workpiece. By the telescoping of the telescopic rod 41, the cutting amount of the workpiece can be controlled, the cutting accuracy is increased, and the support of the limiting plate 42 for the workpiece is improved, thereby enhancing the stability of the workpiece during the cutting process.

[0027] As Figure 2 shown in the figure, a circular groove 5 is opened at the bottom of the pressing plate 103; a rotating shaft 51 is rotatably connected inside the circular groove 5; when working, when the pressing plate 103 extrudes the workpiece, the rotating shaft 51 first contacts the workpiece, and then when the roller 14 starts to feed during operation, the rotating shaft 51 will rotate synchronously inside the circular groove 5. In this step, when feeding, directly increasing the extrusion of the pressing plate 103 may cause too large a frictional force between the pressing plate 103 and the workpiece, resulting in poor feeding effect. Therefore, by increasing the rotation of the rotating shaft 51, the frictional force between the pressing plate 103 and the workpiece is reduced, greatly enhancing the stability of the feeding process of the roller 14.

[0028] As Figure 1 shown in the figure, a safety groove 6 is opened on the outer side of the roller 14; when working, when adjusting the angle of the cutting machine 104 to cut the workpiece, when the cutting is complete, the saw blade of the cutting machine 104 will be inside the safety groove 6. In this step, when cutting the workpiece, it may cause the cutting machine 104 to descend too much, resulting in damage to the roller 14. Therefore, by opening the safety groove 6 on the outer side of the roller 14, the possibility of the cutting machine 104 damaging the roller 14 is reduced.

[0029] As Figure 1 shown in the figure, a protective plate 7 is fixedly connected to one end of the cutting machine 104 away from the cutting table body 1; when working, the protective plate 7 is installed in the middle of the cutting machine 104. In this step, when the operator adjusts the direction of the cutting machine 104, there may be a possibility that the staff does not grasp the handle and directly reaches for the saw blade with their hand. Therefore, the protective plate 7 blocks the hand, reducing the harm that the saw blade may cause to the operator.

[0030] Working principle: Place the workpiece above the roller 14, then turn the rotating handle 102 to drive the 110 to start rotating, causing the threaded slider 101 to lower inside the second grooved fixed block 16, driving the pressing strip 19 to start descending inside the multiple groups of first grooved fixed blocks 15, squeezing the multiple sliding sliders 18, and then the sliding slider 18 squeezes the return spring 17, causing the return spring 17 to start deforming. Since one end of the sliding slider 18 and the threaded slider 101 are both fixedly connected with a pressing plate 103, it drives the pressing plate 103 to squeeze the workpiece above the roller 14. At the same time, pull down the cutting machine 104 to make it reach a suitable position to cut the workpiece. Then drive the servo motor 11 to drive the belt 12 to start rotating, realizing the roller 13 driving the roller 14 to start rotating. Through the rotation of the roller 14, the workpiece is brought closer to the cutting machine 104 to achieve the purpose of cutting. In this step, when cutting metal doors and windows, at the beginning of cutting, a large impact force is likely to be generated directly between the workpiece and the cutting machine 104. Coupled with the uneven feeding speed, the cutting effect is poor, and it may even cause breakage. Therefore, at the beginning of cutting the workpiece, the pressing plate 103 descends to squeeze the upper part of the workpiece, making the workpiece closely adhere to the roller 14, increasing the stability of the workpiece. At the same time, the rotation of the roller 14 will achieve the effect of slow feeding, greatly reducing the possibility of breakage between the workpiece and the cutting machine 104. At the same time, after the cutting machine 104 cuts out the guide groove, other feeding methods can be used to increase the cutting efficiency of the workpiece. First, press the spring limit button 23 to install the limit slider 25 inside the chute 24, and then release the spring limit button 23. The spring limit button 23 will automatically align with the limit hole 22 to limit the limit slider 25, achieving the effect of installing the iron chip collection box 21 on one side of the support column 2. Then, through the cooperation of the spring limit button 23 and the limit hole 22, the height of the iron chip collection box 21 can be adjusted and adjusted to different heights according to the different thicknesses of the workpiece. In this step, when cutting the workpiece, because it is made of metal, a large amount of sparks and metal debris will be generated during the cutting process. These debris and sparks flying everywhere will pollute the working environment and cause damage to the bodies of the staff. Therefore, the iron chip collection box 21 blocks and collects the flying debris, reducing the pollution of the working environment caused by the flying debris. Adjusting the height of the iron chip collection box 21 can make the iron chip collection box 21 in a suitable position and enhance the efficiency of debris collection. When the debris accumulates too much, the debris inside the iron chip collection box 21 can be removed by opening the opening and closing plate 26 for unified treatment. After the work is completed, remove the plug strip 31 installed inside the arc-shaped sliding groove 3, and then turn the cleaning cylinder 32 to make it slide inside the arc-shaped sliding groove 3 and the limit sliding groove 33 to achieve the effect of cleaning the side wall of the iron chip collection box 21. When the cleaning is completed, install the plug strip 31 inside the arc-shaped sliding groove 3. In this step, when collecting the flying debris, some debris may be adsorbed on the side wall of the cutting table main body 1 and is not easy to clean,Long-term accumulation may reduce the service life of the iron filings collection box 21. Therefore, the inside of the iron filings collection box 21 is cleaned by the cleaning cylinder 32, which increases the service life of the iron filings collection box 21. When the workpiece is placed above the roller 14, the driving telescopic rod 41 starts to expand and contract, driving the limiting plate 42 to extrude the workpiece from the side. In this step, when cutting the workpiece, some special requirements may result in less cutting amount on one side of the workpiece. By expanding and contracting the telescopic rod 41, the cutting amount of the workpiece can be controlled, increasing the cutting accuracy and improving the support of the limiting plate 42 for the workpiece, thus enhancing the stability of the workpiece during the cutting process. When the pressing plate 103 extrudes the workpiece, the rotating shaft 51 first contacts the workpiece. Then, when the roller 14 starts to feed the material, the rotating shaft 51 will rotate synchronously in the circular groove 5. In this step, when feeding the material, directly increasing the extrusion of the pressing plate 103 may cause excessive friction between the pressing plate 103 and the workpiece, resulting in poor feeding effect. Therefore, by increasing the rotation of the rotating shaft 51, the friction between the pressing plate 103 and the workpiece is reduced, greatly enhancing the stability of the roller 14 during the feeding process. When adjusting the angle of the cutting machine 104 to cut the workpiece, when the cutting is complete, the saw blade of the cutting machine 104 will be inside the safety groove 6. In this step, when cutting the workpiece, it may cause the cutting machine 104 to descend too much, resulting in damage to the roller 14. Therefore, by opening the safety groove 6 on the outside of the roller 14, the possibility of the cutting machine 104 damaging the roller 14 is reduced. The protective plate 7 is installed in the middle of the cutting machine 104. In this step, when the operator adjusts the direction of the cutting machine 104, there may be a possibility that the operator does not grasp the handle and directly reaches for the saw blade with the hand. Therefore, the protective plate 7 blocks the hand, reducing the harm that the saw blade may cause to the operator.,
