Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a laser cutting machine for cutting metal plates. Background Art

[0002] The laser cutting machine is a machine that focuses the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. Laser cutting processing has the characteristics of high precision, fast cutting, no limitation on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It is widely used, for example, laser cutting machines can be used to cut metal sheets into finished products of specified shapes.

[0003] The existing laser cutting machines gradually exposed their shortcomings during use, mainly in the following aspects:

[0004] First, it is difficult to remove the finished cut products in the slit of the metal plate, and the process of collecting and placing the finished cut products is slow. Specifically, after the laser cutting gun cuts the metal plate, the finished cut products are located in the slit, and the slit formed by the laser cutting gun when cutting the metal plate is narrow. The staff cannot directly put their fingers into the slit to remove the finished cut products, and need to use tools such as picking needles to pick out the finished cut products. Therefore, it is difficult to remove the finished cut products in the slit of the metal plate, and after the finished cut products are taken out, in order to prevent the edges and corners from being damaged, the staff need to pick them up and place them gently when collecting and placing them. Therefore, the process of collecting and placing the finished cut products is slow. The above two situations all lead to low cutting efficiency.

[0005] Second, cleaning cutting waste not only requires stopping the machine and disassembling operations, but also the process is cumbersome. Specifically, when the laser cutting gun cuts metal sheets, a large amount of metal debris will be generated. The metal debris will pass through the sword grid on the machine tool and fall into the inside. When a large amount of metal debris accumulates, it is easy to enter the precision parts of the machine and cause damage to the machine. Therefore, the metal debris in the machine tool needs to be cleaned regularly. When cleaning the metal debris in the machine tool, it is necessary to shut down the equipment and disassemble the sword grid, and then use cleaning tools to clean the metal debris inside the machine tool.

[0006] Third, the positioning accuracy of the cutting area is low. Specifically, the laser cutting gun can continuously cut metal sheets driven by the three-axis module. When the moving range of the three-axis module reaches its limit, the staff needs to drag the unprocessed area of ​​the metal sheet into the moving area of ​​the three-axis module. This does not prevent the laser cutting gun from moving outside the metal sheet during the cutting process, resulting in failure of the cutting product. The staff needs to position the cutting area of ​​the metal sheet, but the sword grid on the machine tool does not have any reference base points. The staff has a large error when manually adjusting the area to be cut of the metal sheet, which leads to a high defective rate of the finished product.

[0007] Fourth, the post-processing process of the metal sheet waste is complicated. Specifically, after the metal sheet is cut, the waste needs to be divided and then the divided metal sheets need to be collected. Therefore, the post-processing process of the metal sheet waste is complicated.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0009] In view of the defects in the prior art, the technical problem to be solved by the present invention is to provide a laser cutting machine for cutting metal plates, which can automatically and quickly take out the cut products from the cut seam and transfer them to a collection container quickly and stably, thereby improving the cutting efficiency of the metal plates;

[0010] The laser cutting machine can automatically collect the metal scraps generated during the cutting of metal sheets, effectively preventing the metal scraps from scattering all over the equipment and eliminating the process of cleaning the metal scraps.

[0011] The laser cutting machine can also automatically locate the cutting area of ​​the metal sheet, which improves the positioning accuracy of the cutting area of ​​the metal sheet and reduces the defective rate of the finished product;

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. When cutting metal sheets, place the metal sheets on the support rollers and push one end of it to the top of the fixed box. The three-axis module drives the laser cutting gun to move and then cut the metal sheets. After the laser cutting gun completes one cut, the finished product is supported on the sword grid. The drive motor drives the drive shaft to rotate rapidly until the sword grid is completely inserted into the receiving slot. The finished product falls down into the transfer box. The lifting and telescopic cylinder drives the lifting U-shaped plate and the waste collection box to move downward to avoid it. The rotating motor drives the rotating plate, the fixed cylinder and the transfer box to rotate 180°. At this time, the transfer box with the finished product is located below the discharge box, and the empty transfer box is located below the fixed box. The electric control telescopic cylinder drives the connecting plate, the support cylinder and the transfer box to rotate 180°. The support cylinder and the discharge box move downward until the open end of the discharge box abuts against the open end of the transfer box. At this time, the support cylinder and the fixed cylinder are coaxial, and the rotating built-in motor and the adjusting built-in motor respectively drive the discharge box and the transfer box to rotate 180° synchronously, and the finished cut products in the transfer box fall into the discharge box, and the two-way telescopic cylinder drives the two limit plates to move toward each other until the finished cut products in the discharge box are clamped, and the electric-controlled telescopic cylinder drives the discharge box to move into the finished cut product collection box. During the downward movement of the discharge box, the rotating built-in motor drives the discharge box to rotate 180° again. At this time, the opening end of the discharge box is downward, and when the discharge box drops to a suitable height for placing the cut products, the two-way telescopic cylinder drives the two limit plates to reset and then release the In addition to the restrictions on the finished cut products, the finished cut products fall into the finished cut product collection box for collection, and then the discharge box and the transfer box are reset. In the process of transferring the finished cut products to the finished cut product collection box, the lifting telescopic cylinder drives the waste collection box to move upward until the waste collection box and the empty transfer box are against each other. The telescopic cylinder drives the sliding U-shaped plate and the metal sheet to move longitudinally, and the laser cutting gun cuts the longitudinal uncut area of ​​the metal sheet. Repeat the above operation of transferring the finished cut products and then collect the finished cut products. After the longitudinal area of ​​the metal sheet with a fixed length is completely cut, the clamping L-shaped plate close to the metal sheet moves toward the metal sheet under the drive of the control telescopic cylinder, and the pneumatic The telescopic cylinder drives the sliding clamping plate to slide downward until the sliding clamping plate and the clamping L-shaped plate clamp the metal sheet. After the telescopic end of the telescopic cylinder is controlled to retract and drive the metal sheet to move horizontally by a preset length, the three-axis module drives the laser cutting gun to move and cut the remaining material in the cut area of ​​the metal sheet. The clamping L-shaped plate transfers the remaining material of the cut metal sheet. After that, the laser cutting gun cuts the uncut area of ​​the adjusted metal sheet again. The above cutting process is repeated to continuously cut the metal sheet. The laser cutting machine can automatically take out the cut product from the cut seam and transfer it to the cut product collection box quickly and stably, thereby improving the cutting efficiency of the metal sheet.

[0028] 2. The metal scraps generated during the cutting process of the metal sheet by the laser cutting gun pass through the sword fence and the fixed box and fall into the transfer box. Some of the metal scraps directly pass through the leakage hole and enter the scrap collection box for collection. The rest of the metal scraps fall into the gap between the leakage holes at the bottom of the transfer box. The small vibration motor drives the transfer box to vibrate, thereby vibrating the metal scraps in the transfer box and passing through the leakage hole into the scrap collection box for collection. The laser cutting machine can automatically collect the metal scraps generated during the cutting of the metal sheet, effectively preventing the metal scraps from scattering everywhere in the equipment and eliminating the process of cleaning the metal scraps.

[0029] 3. After a certain amount of metal scraps are collected in the scrap collection box, the lifting and telescopic cylinder drives the scrap collection box to move downward, and the steering motor drives the scrap collection box to rotate. The staff can quickly clean and transfer the metal scraps in the scrap collection box, which improves the practicality of the equipment;

[0030] 4. During the continuous cutting of metal sheets, the driving telescopic cylinder can drive the sliding U-shaped plate to slide horizontally, thereby adjusting and positioning the longitudinal cutting area of ​​the metal sheet. The clamping L-shaped plate and the sliding clamping plate can clamp the metal sheet, and the transverse cutting area of ​​the metal sheet can be adjusted and positioned under the driving of the control telescopic cylinder. The laser cutting machine can automatically position the cutting area of ​​the metal sheet, improve the positioning accuracy of the cutting area of ​​the metal sheet, and reduce the defective rate of the finished product;

[0031] 5. After the remaining material in the cut area of ​​the metal sheet is cut, the control motor drives the adjustment plate and the clamping L-shaped plate to rotate 180°, and the remaining metal sheet held by the clamping L-shaped plate and the sliding clamping plate rotates to the outside of the cutting table. The built-in adjustment motor drives the rotating block and the clamping L-shaped plate to rotate downward 90°. At this time, the clamped remaining metal sheet is downward toward the waste plate collection box, and the control telescopic cylinder drives the clamping L-shaped plate and the remaining metal sheet to move downward into the waste plate collection box. The sliding clamping plate is reset and the restriction on the remaining metal sheet is released. At this point, the collection of the remaining metal sheet is completed. The laser cutting machine can automatically divide and transfer the remaining material during the process of cutting the metal sheet, which simplifies the post-processing process of the remaining metal sheet.

[0057] The working principle of this device is:

[0058] When cutting the metal sheet 53, the metal sheet 53 is placed on the supporting roller 12 and one end of it is pushed above the fixed box 23, and the three-axis module 11 drives the laser cutting gun 10 to move, and then cuts the metal sheet 53. After the laser cutting gun 10 completes one cutting, the cut product is supported on the sword grid 34, and the driving motor 33 drives the driving shaft 35 to rotate rapidly until the sword grid 34 completely enters the receiving groove 22, and the cut product falls downward into the transfer box 32. The lifting and telescopic cylinder 28 drives the lifting U-shaped plate 27 and the waste collection box 29 to move downward for avoidance, and the rotating motor 20 drives the rotating plate 30, the fixed cylinder 19 and the transfer box 32 to rotate 180°. At this time, the transfer box 32 with the cut product is located below the discharge box 39, and the empty The transfer box 32 is located below the fixed box 23, and the electrically-controlled telescopic cylinder 6 drives the connecting plate 4, the supporting cylinder 2 and the discharge box 39 to move downward until the open end of the discharge box 39 abuts against the open end of the transfer box 32. At this time, the supporting cylinder 2 and the fixed cylinder 19 are coaxial, and the rotating built-in motor 37 and the adjusting built-in motor 36 respectively drive the discharge box 39 and the transfer box 32 to rotate 180° synchronously, and the cut products in the transfer box 32 fall into the discharge box 39. The two-way telescopic cylinder 42 drives the two limit plates 40 to move toward each other until the cut products in the discharge box 39 are clamped, and the electrically-controlled telescopic cylinder 6 drives the discharge box 39 to move into the cut product collection box 17. During the downward movement of the discharge box 39, the rotating built-in motor 37 drives the discharge box 39 to rotate 180° again. The opening end of the discharge box 39 is downward, and when the discharge box 39 is lowered to a suitable height for placing the cut product, the two-way telescopic cylinder 42 drives the two limit plates 40 to reset and thus release the restriction on the cut product, and the cut product falls into the cut product collection box 17 for collection, and then the discharge box 39 and the transfer box 32 are reset. In the process of transferring the cut product to the cut product collection box 17, the lifting telescopic cylinder 28 drives the waste collection box 29 to move upward until the waste collection box 29 is against the empty transfer box 32, and the telescopic cylinder 14 is driven to drive the sliding U-shaped plate 13 and the metal sheet 53 to move longitudinally, and the laser cutting gun 10 cuts the longitudinal uncut area of ​​the metal sheet 53, and repeats the above-mentioned operation of transferring the cut product to further cut the cut product. After all the longitudinal areas of the metal sheet 53 with a fixed length have been cut, the clamping L-shaped plate 48 close to the metal sheet 53 moves toward the metal sheet 53 under the drive of the control telescopic cylinder 47, and the pneumatic telescopic cylinder 49 drives the sliding clamping plate 50 to slide downward until the sliding clamping plate 50 and the clamping L-shaped plate 48 clamp the metal sheet 53. After the telescopic end of the control telescopic cylinder 47 contracts and drives the metal sheet 53 to move horizontally by a preset length, the three-axis module 11 drives the laser cutting gun 10 to move and cut the remaining material in the cut area of ​​the metal sheet 53. The clamping L-shaped plate 48 transfers the remaining material of the cut metal sheet 53, and then the laser cutting gun 10 cuts the uncut area of ​​the adjusted metal sheet 53 again.The above-mentioned cutting process is repeated to continuously cut the metal sheet 53. The laser cutting machine can automatically take out the cut product from the cut seam and transfer it to the cut product collection box 17 quickly and stably, thereby improving the cutting efficiency of the metal sheet 53.

[0059] The metal scraps generated during the cutting process of the metal sheet 53 by the laser cutting gun 10 pass through the sword fence 34 and the fixed box 23 and fall into the transfer box 32. Some of the metal scraps directly pass through the leak hole 31 and enter the scrap collection box 29 for collection, and the remaining metal scraps fall into the gap between the leak hole 31 at the bottom of the transfer box 32. The small vibration motor 24 drives the transfer box 32 to vibrate, thereby vibrating the metal scraps in the transfer box 32 and allowing them to pass through the leak hole 31 and enter the scrap collection box 29 for collection. The laser cutting machine can automatically collect the generated metal scraps during the cutting process of the metal sheet 53, effectively preventing the metal scraps from being scattered all over the equipment, and eliminating the process of cleaning the metal scraps.

[0060] After a certain amount of metal scraps are collected in the scrap collection box 29, the lifting and telescopic cylinder 28 drives the scrap collection box 29 to move downward, and the turning motor 25 drives the scrap collection box 29 to rotate, so that the staff can quickly clean and transfer the metal scraps in the scrap collection box 29, thereby improving the practicality of the equipment;

[0061] During the continuous cutting of the metal sheet 53, the driving telescopic cylinder 14 can drive the sliding U-shaped plate 13 to slide horizontally, thereby adjusting and positioning the longitudinal cutting area of ​​the metal sheet 53, the clamping L-shaped plate 48 and the sliding clamping plate 50 can clamp the metal sheet 53, and the transverse cutting area of ​​the metal sheet 53 can be adjusted and positioned under the driving of the control telescopic cylinder 47. The laser cutting machine can automatically position the cutting area of ​​the metal sheet 53, thereby improving the positioning accuracy of the cutting area of ​​the metal sheet 53 and reducing the defective rate of the finished product.

[0062] After the remaining material in the cut area of ​​the metal sheet 53 is cut, the control motor 44 drives the adjustment plate 45 and the clamping L-shaped plate 48 to rotate 180°, and the remaining material of the metal sheet 53 clamped by the clamping L-shaped plate 48 and the sliding clamping plate 50 rotates to the outside of the cutting table 1, and the built-in adjustment motor 51 drives the rotating block 46 and the clamping L-shaped plate 48 to rotate downward 90°. At this time, the clamped remaining material of the metal sheet 53 is downward toward the waste plate collection box 3, and the control telescopic cylinder 47 drives the clamping L-shaped plate 48 and the remaining material of the metal sheet 53 to move downward into the waste plate collection box 3, and the sliding clamping plate 50 is reset and releases the restriction on the remaining material of the metal sheet 53. At this point, the collection of the remaining material of the metal sheet 53 is completed. The laser cutting machine can automatically divide and transfer the remaining material during the process of cutting the metal sheet 53, thereby simplifying the post-processing process of the remaining material of the metal sheet 53.
