[0016] Compared with the prior art, the present invention provides a plate cutting device for fire box production, which has the following beneficial effects: 1. For the plate cutting device used in the production of fire cabinets, during the asynchronous processing of metal plates in the upper and lower conveying paths, when metal plates need to be replenished in one of the conveying paths, the working state of the laser cutting head is stopped, and the guiding conveying plate replenishes the metal plates into the conveying path of one layer. After the metal plates move to the processing position, the laser cutting head resumes operation again, so that the metal plates on the conveying path of one layer start cutting from the cutting processing state point of the metal plates in the conveying path of the other layer. After the metal plates in the conveying path of the other layer are cut and processed, they are discharged and replenished with metal plates. Then the laser cutting head resets and starts a new round of cutting process. Until the metal plates in the conveying path of one layer are completed and reach the cutting processing state point on the processing position, the laser cutting head stops running again, and the metal plates in the conveying path of one layer are replaced again. That is, when the cutting processing of the metal plates on the upper and lower conveying paths is asynchronous, the processing process of the laser cutting head is maintained and the process is repeated. At each node during the processing of the metal plates, the laser cutting head stops running. When the metal plates are replenished and replaced, the laser cutting head resumes the previous state of operation again, thus replacing the current one-by-one processing flow mode of the metal plates, enabling a significant change in the processing efficiency of the cutting device, improving the processing efficiency of the cutting device, eliminating the drawback that only additional equipment can be used to handle large production capacity requirements, and improving the applicability of the cutting device.

[0017] 2. For the plate cutting device used in the production of fire cabinets, through the setting of the spring, after the baffle moves, the moving part will press the spring to contract, so as to utilize the elasticity of the spring to complete the reset of the baffle and ensure the stability of the operation of the cutting device.

[0018] 3. For the plate cutting device used in the production of fire cabinets, through the setting of the baffle, when the guiding conveying plate does not guide the metal plates, the baffle can block the metal plates conveyed into the cutting device, so that the metal plates can be replenished when there is a shortage in the cutting device, avoiding the accumulation of metal plates from affecting the cutting processing process and improving the processing quality of the cutting device.

Specific embodiments

[0021] 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 creative efforts shall fall within the protection scope of the present invention.

[0022] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a plate cutting device for fire box production.

[0023] Embodiment 1. In a typical embodiment of the present application, as Figure 1 shown, a plate cutting device for fire box production includes a machine body 1, a cutting mechanism 2 provided on the machine body 1, and an auxiliary mechanism 3 provided on the machine body 1. The cutting mechanism 2 includes a cross beam 22 and a laser cutting head 27. A cross beam 22 is provided on the machine body 1, and a laser cutting head 27 is provided on the cross beam 22. The cross beam 22 drives the laser cutting head 27 to move on the machine body 1, and the laser cutting head 27 moves vertically on the cross beam 22 for cutting treatment; The auxiliary mechanism 3 includes a conveying roller 32 and a guiding conveying plate 312. A plurality of conveying rollers 32 are provided on the machine body 1. The conveying rollers 32 are divided into upper and lower two-layer conveying paths. A guiding conveying plate 312 is provided on the machine body 1. The guiding conveying plate 312 is located on one side of the overall conveying rollers 32 and between the upper and lower two-layer conveying paths. The guiding conveying plate 312 guides the metal plates conveyed to the cutting device, so that the metal plates are diverted into each conveying path.

[0024] When using the present invention: The guiding and conveying plate 312 guides the metal sheet conveyed to the cutting device, so that the metal sheet is shunted and conveyed to the upper and lower two-layer conveying paths by the guiding and conveying plate 312. After the metal sheet moves to the processing area on the conveying path, the conveying roller 32 in the conveying path stops running. Then, the cross beam 22 drives the laser cutting head 27 to move on the machine body 1, so that the laser cutting head 27 performs laser cutting processing on the metal sheets on the upper and lower two-layer conveying paths at the same time. At this time, it is a synchronous processing process of the metal sheets in the upper and lower two-layer conveying paths. When the metal sheets in the upper and lower two-layer conveying paths are processed asynchronously, metal sheets need to be replenished in one of the conveying paths. The working state of the laser cutting head 27 is stopped, and the guiding and conveying plate 312 replenishes the metal sheets into one of the conveying paths. After the metal sheet moves to the processing position, the laser cutting head 27 continues to run again, so that the metal sheet on one of the conveying paths starts cutting from the cutting processing state point of the metal sheet in the other conveying path. The metal sheet in the other conveying path is discharged and replenished after cutting processing. Then, the laser cutting head 27 resets and starts a new round of cutting process until the metal sheet in one of the conveying paths reaches the cutting processing state point at the processing position. The laser cutting head 27 stops running again, and the metal sheet in one of the conveying paths is replaced again. That is, when the cutting processing process of the metal sheets on the upper and lower conveying paths is asynchronous, the processing process of the laser cutting head 27 is maintained (for example, compared to a 0-1 processing process) and the process is repeated. At each node in the metal sheet processing (i.e., the replacement of the metal sheet), the laser cutting head 27 stops running. After the metal sheet is replenished and replaced, the laser cutting head 27 continues to run in the just state again (for example, stops running at the processing process point of 0.6, and when running again, continues to process from the processing process point of 0.6), thereby replacing the current one-by-one processing pipeline method of the metal sheet, enabling the processing efficiency of the cutting device to be changed greatly, improving the processing efficiency of the cutting device, eliminating the drawback that only equipment can be increased when there is a large production capacity demand, and improving the applicability of the cutting device.

[0025] Example 2, as Figures 2 - 4 shown, the difference from the above embodiment is that the cutting mechanism 2 further includes a guide rail 21. The guide rail 21 is fixedly installed on the machine body 1. The length of the guide rail 21 is the same as the length of the machine body 1. A cross beam 22 is slidably fitted on the guide rail 21. The width of the cross beam 22 is the same as the width of the machine body 1. There is a gap between the middle of the cross beam 22 and the machine body 1, and the metal sheet passes through the gap between the cross beam 22 and the machine body 1.

[0026] Further, a first linkage 23 is fixedly installed at the bottom end of the cross beam 22. The first linkage 23 is located in the middle of the machine body 1. A first screw rod 24 is rotatably fitted on the machine body 1. The length of the first screw rod 24 is the same as the length of the machine body 1. The first screw rod 24 penetrates through the first linkage 23, and the first screw rod 24 is in threaded fit with the first linkage 23. A first stepping motor 25 is fixedly installed on the machine body 1, and the first stepping motor 25 is power-connected to the first screw rod 24.

[0027] Among them, when moving the cross beam 22, the first stepping motor 25 is started. The first stepping motor 25 drives the first screw rod 24 to rotate. The first screw rod 24 drives the first linkage 23 to move on the machine body 1, and the first linkage 23 drives the cross beam 22 to move on the machine body 1.

[0028] Further, a suspension 26 is slidably fitted on the cross beam 22. A laser cutting head 27 is slidably fitted on the suspension 26. The laser cutting head 27 is located below the suspension 26. The moving track of the laser cutting head 27 covers the plane position where the conveying rollers 32 are integrally arranged. A hydraulic rod 28 is arranged on the suspension 26. The fixed rod of the hydraulic rod 28 is fixedly connected to the suspension 26. The extending rod of the hydraulic rod 28 faces downward, and the extending rod of the hydraulic rod 28 is fixedly connected to the laser cutting head 27.

[0029] Further, the laser cutting head 27 is a prior art. Specifically, the laser cutting head 27 uses laser to heat the metal to complete the cutting process by melting the metal at high temperature.

[0030] Further, a second linkage 29 is fixedly installed on the suspension 26. The second linkage 29 is located inside the cross beam 22. The second linkage 29 penetrates through the wall surface of the cross beam 22. The position of the wall surface of the cross beam 22 does not cover the moving track of the second linkage 29. A second screw rod 210 is rotatably fitted inside the cross beam 22. The length of the second screw rod 210 is the same as the length of the cross beam 22. The second screw rod 210 penetrates through the second linkage 29, and the second screw rod 210 is in threaded fit with the second linkage 29. A second stepping motor 211 is fixedly installed inside the cross beam 22, and the second stepping motor 211 is power-connected to the second screw rod 210.

[0031] Among them, when the laser cutting head 27 performs the cutting process, the second stepping motor 211 is started. The second stepping motor 211 drives the second screw rod 210 to rotate. The second screw rod 210 drives the second linkage 29 to move on the cross beam 22. The second linkage 29 drives the suspension 26 to move on the cross beam 22. The cross beam 22 drives the laser cutting head 27 to move, so that the laser cutting head 27 uses the movement of the cross beam 22 and the movement of the suspension 26 to complete the movement of the laser cutting head 27 at the processing position. Then the hydraulic rod 28 is started, and the hydraulic rod 28 drives the laser cutting head 27 to lean against the metal plate, so that the laser cutting head 27 completes the cutting process on the metal plate.

[0032] Example 3, as Figures 5 - 8 shown, the difference from the above embodiment is that the auxiliary mechanism 3 further includes a steady rest 31. The steady rest 31 is fixedly installed on the machine body 1. The steady rest 31 is divided into two parts and symmetrically distributed on both sides of the machine body 1. The whole steady rest 31 is located in the gap between the cross beam 22 and the machine body 1. A plurality of conveying rollers 32 are rotatably fitted on the steady rest 31. The overall distribution length of the conveying rollers 32 is adapted to the length of the machine body 1. The conveying rollers 32 are evenly distributed in a straight line on the steady rest 31. The conveying rollers 32 are symmetrically arranged in upper and lower parts, so that the conveying rollers 32 form an upper and lower two-layer conveying path.

[0033] Furthermore, a plurality of sprockets 33 are rotatably fitted on the steady rest 31. The sprockets 33 are symmetrically distributed on both sides of the steady rest 31. The number of sprockets 33 on each side is adapted to the respective ends of the conveying rollers 32. Each side of the sprockets 33 is power-connected to the respective ends of the conveying rollers 32. A chain 34 is tensioned on each side of the sprockets 33. The overall distribution of the chain 34 is adapted to the upper and lower two-layer conveying path of the conveying rollers 32. A plurality of transfer motors 35 are fixedly installed on the steady rest 31. The transfer motors 35 are power-connected to the sprockets 33.

[0034] Among them, when conveying the metal sheet, the transfer motor 35 is started. The transfer motor 35 drives the sprocket 33 to rotate. The sprocket 33 drives the chain 34 to rotate. The chain 34 drives the overall sprocket 33 to rotate. The sprocket 33 drives the conveying roller 32 to rotate, so that the metal sheet is transferred between the steady rests 31 by using the conveying roller 32.

[0035] Furthermore, a plurality of limit guide plates 36 are fixedly installed on both sides of the steady rest 31. The limit guide plates 36 are evenly distributed in the upper and lower two-layer conveying path of the conveying rollers 32. The limit guide plates 36 are adjacent to the conveying rollers 32. The limit guide plates 36 are used to limit the metal sheet so that the metal sheet is stably located in the middle part of the conveying rollers 32.

[0036] Among them, when the metal sheet is transferred on the conveying roller 32, the limit guide plate 36 restricts the position of the metal sheet, so that the metal sheet can only be transferred in the middle part of the conveying roller 32, and the side completes the restriction of the metal sheet being transferred to the processing position.

[0037] Further, one end of the center frame 31 is fixedly installed with a vertical rail 37. The vertical rail 37 is located at the input end of the conveying path. A plurality of moving members 38 are slidably fitted on the vertical rail 37. The moving members 38 are symmetrically distributed up and down. Baffles 39 are fixedly installed on the moving members 38. The positions where the baffles 39 are respectively arranged on each conveying path are at the same height. A plurality of springs 310 are arranged in the vertical rail 37. The springs 310 are all located between the moving members 38 and the vertical rail 37. One end of the spring 310 is fixedly connected to the vertical rail 37, and the other end of the spring 310 is fixedly connected to the moving member 38.

[0038] Further, one end of the center frame 31 is rotatably fitted with a side shaft rod 311. The side shaft rod 311 is adjacent to the moving member 38. A guiding conveying plate 312 is fixedly installed on the side shaft rod 311. The guiding conveying plate 312 is adjacent to the conveying roller 32. The length of the guiding conveying plate 312 is adapted to the conveying roller 32. A rotating shaft cylinder 313 is fixedly installed on the center frame 31. The rotating shaft cylinder 313 is power-connected to the side shaft rod 311. An extension column 314 is fixedly installed at the bottom end of the upper moving member 38. Push rods 315 are fixedly installed on both the extension column 314 and the lower moving member 38. The rotating trajectory of the guiding conveying plate 312 covers the positions of the push rods 315. The guiding conveying plate 312 is located between the upper and lower push rods 315.

[0039] Further, in the initial state of the guiding conveying plate 312, the guiding conveying plate 312 is placed between the push rods 315 and does not come into contact with any push rod 315.

[0040] Among them, in the diversion of the metal sheet, the rotating shaft cylinder 313 is started. The rotating shaft cylinder 313 drives the side shaft rod 311 to rotate. The side shaft rod 311 drives the guiding conveying plate 312 to deflect, so that the guiding conveying plate 312 turns towards the conveying path of one layer. The deflection of the guiding conveying plate 312 pushes the push rod 315 to move. The push rod 315 drives the moving member 38 to move on the vertical rail 37. The moving member 38 drives the baffle 39 to move, so that the baffle 39 moves away from the blockage of the conveying path of one layer, thereby guiding the metal sheet into the conveying path of one layer by the guiding conveying plate 312.

[0041] The working principle of the whole cutting device: The metal sheet conveyed to the cutting device is guided by the guiding and conveying plate 312, so that the metal sheet is shunted and conveyed to the upper and lower two-layer conveying paths by the guiding and conveying plate 312. After the metal sheet moves to the processing area on the conveying path, the conveying roller 32 in the conveying path stops running. Then the cross beam 22 drives the laser cutting head 27 to move on the machine body 1, so that the laser cutting head 27 performs laser cutting processing on the metal sheets on the upper and lower two-layer conveying paths at the same time. At this time, it is a synchronous processing process for the metal sheets in the upper and lower two-layer conveying paths. When the metal sheets in the upper and lower two-layer conveying paths are processed asynchronously, metal sheets need to be supplemented in one layer of the conveying path. The working state of the laser cutting head 27 is stopped, and the guiding and conveying plate 312 supplements metal sheets to one layer of the conveying path. After the metal sheet moves to the processing position, the laser cutting head 27 runs again, so that the metal sheet on one layer of the conveying path starts cutting from the cutting processing state point of the metal sheet in the other layer of the conveying path. After the metal sheet in the other layer of the conveying path is cut and processed, it is discharged and supplemented with metal sheets. Then the laser cutting head 27 resets and starts a new round of cutting process until the metal sheet in one layer of the conveying path is completed and reaches the cutting processing state point on the processing position. The laser cutting head 27 stops running again, and the metal sheet in one layer of the conveying path is replaced again. That is, when the cutting processing of the metal sheets on the upper and lower conveying paths is asynchronous, the processing process of the laser cutting head 27 is maintained at this time (for example, compared to a 0-1 processing process) and the process is repeated. At each node in the metal sheet processing (that is, the replacement of the metal sheet), the laser cutting head 27 stops running. When the metal sheet is completed with supplementation and replacement, the laser cutting head 27 runs again in the just state (for example, stops running at the processing process point of 0.6, and when running again, continues to process from the processing process point of 0.6), thus replacing the current one-by-one processing pipeline method of the metal sheet, enabling the processing efficiency of the cutting device to be changed greatly, improving the processing efficiency of the cutting device, eliminating the disadvantage that only equipment processing can be increased when there is a large production capacity demand, and improving the applicability of the cutting device; Among them, when moving the cross beam 22, the first stepping motor 25 is started. The first stepping motor 25 drives the first screw rod 24 to rotate. The first screw rod 24 drives the first linkage 23 to move on the machine body 1. The first linkage 23 drives the cross beam 22 to move on the machine body 1; When the laser cutting head 27 performs cutting processing, the second feed motor 211 is started. The second feed motor 211 drives the second screw rod 210 to rotate. The second screw rod 210 drives the second linkage 29 to move on the cross beam 22. The second linkage 29 drives the suspension 26 to move on the cross beam 22. The cross beam 22 drives the laser cutting head 27 to move, so that the laser cutting head 27 uses the movement of the cross beam 22 and the movement of the suspension 26 to complete the movement of the laser cutting head 27 at the processing position. Then, the hydraulic rod 28 is started. The hydraulic rod 28 drives the laser cutting head 27 to lean against the metal plate, so that the laser cutting head 27 completes the cutting processing on the metal plate; When conveying the metal plate, the conveyor motor 35 is started. The conveyor motor 35 drives the sprocket 33 to rotate. The sprocket 33 drives the chain 34 to rotate. The chain 34 drives the overall sprocket 33 to rotate. The sprocket 33 drives the conveying roller 32 to rotate, so that the metal plate is transferred between the center frames 31 by the conveying roller 32; When the metal plate is transferred on the conveying roller 32, the limit guide plate 36 restricts the position of the metal plate, so that the metal plate can only be transferred in the middle part of the conveying roller 32, and the side completes the restriction of transferring the metal plate to the processing position; During the diversion of the metal plate, the rotating shaft cylinder 313 is started. The rotating shaft cylinder 313 drives the side shaft rod 311 to rotate. The side shaft rod 311 drives the guiding conveying plate 312 to deflect, so that the guiding conveying plate 312 turns to the conveying path towards the first layer. The deflection of the guiding conveying plate 312 pushes the push rod 315 to move. The push rod 315 drives the moving part 38 to move on the vertical rail 37. The moving part 38 drives the baffle 39 to move, so that the baffle 39 moves away from blocking the conveying path of the first layer, so that the guiding conveying plate 312 guides the metal plate into the conveying path of the first layer.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
