Description

Technical Field

[0001] The present invention relates to the technical field of aluminum sheet cutting, and particularly to a numerically controlled cutting device with a dust suction structure for aluminum sheet processing. Background Art

[0002] Aluminum sheet is a type of aluminum material. It refers to the plate-shaped aluminum products finally manufactured by plastic processing methods such as rolling, extrusion, stretching, and forging of aluminum billets. In order to ensure the final performance of the sheet, annealing, solution treatment, quenching, natural aging, and artificial aging treatments are carried out on the finished product. During the processing of aluminum sheets, numerical control cutting equipment is required to cut them.

[0003] During the use of the existing numerically controlled cutting equipment for aluminum sheet processing, in order to avoid the chips generated during the cutting of aluminum sheets from contaminating the workbench, a dust suction structure is usually installed outside the cutting machine, and the chips generated during the cutting process are collected through this dust suction structure. However, during the cutting of aluminum sheets, a large amount of chips adhere to the inside and outside of the aluminum sheet itself, and the dust suction structure cannot collect all of these chips. During the movement of the cut aluminum sheet on the workbench, some chips will be retained on the workbench, resulting in the dust suction structure being unable to achieve a better chip collection effect and reducing the use value of the numerically controlled cutting equipment with a dust suction structure. Summary of the Invention

[0004] The present invention discloses a numerically controlled cutting device with a dust suction structure for aluminum sheet processing, aiming to solve the technical problem that during the use of the existing numerically controlled cutting equipment for aluminum sheet processing, in order to avoid the chips generated during the cutting of aluminum sheets from contaminating the workbench, a dust suction structure is usually installed outside the cutting machine, and the chips generated during the cutting process are collected through this dust suction structure. However, during the cutting of aluminum sheets, a large amount of chips adhere to the inside and outside of the aluminum sheet itself, and the dust suction structure cannot collect all of these chips. During the movement of the cut aluminum sheet on the workbench, some chips will be retained on the workbench.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A numerical control cutting device with a dust suction structure for aluminum sheet processing, including a machine tool. At the four corners of the bottom of the machine tool, grounding seats are fixedly connected. And a blanking hole is opened at the top of the middle part of the machine tool. A blanking dust suction assembly is arranged below the blanking hole of the machine tool. The blanking dust suction assembly includes a blanking plate. And a plurality of shock spring rods I are fixedly connected to the top of the blanking plate at equal intervals. The tops of the plurality of shock spring rods I are fixedly connected to the same mounting plate. The mounting plate is fixedly connected to the bottom of the machine tool. Shock spring rods II are fixedly connected to the inclined surface of the blanking plate at equal intervals. And one end of each shock spring rod II is fixedly connected with a contact arc block. Perforations are opened at the top of the blanking plate between every two rows of contact arc blocks. A diversion arc piece is fixedly connected to the outer side wall of the bottom end of the blanking plate. Side dust suction plates are fixedly connected to both sides of the blanking plate. And dust suction holes I are opened on the opposite sides of the two side dust suction plates. The two side dust suction plates penetrate the upper and lower surfaces of the blanking plate. Connecting holes are opened on the opposite sides of the two side dust suction plates. The same connecting pipe is fixedly connected inside the two connecting holes. On the same side of two of the grounding seats, the same dust suction box I is fixedly connected. A dust suction pump I is fixedly connected to the top of the dust suction box I. The dust suction end of the dust suction pump I is inserted into the inside of the connecting pipe through a pipeline. And the dust conveying end of the dust suction pump I is connected to the inside of the dust suction box I through a pipeline.

[0007] By setting up the blanking dust suction assembly, after the aluminum sheet is cut, the hydraulic cylinder II drives the positioning clamping plate to loosen the clamping of one end of the cut aluminum sheet. Then the aluminum sheet slides down along the inclined guide plate at the clamping frame. When the aluminum sheet falls onto the lower blanking plate, the weight of the aluminum sheet impacts the blanking plate, making the shock spring rods I in a shock state, so as to realize the preliminary shock impurity removal of the aluminum sheet. As the aluminum sheet slides down, it is squeezed against each contact arc block. The shock spring rods II drive the aluminum sheet to perform secondary shock impurity removal. At the same time, start the dust suction pump I. The dust suction pump I collects the dropped aluminum slag through the dust suction holes I on the two side dust suction plates, ensuring that the debris attached to the cut aluminum sheet is completely separated, improving the dust suction effect of the numerical control cutting device, and avoiding the pollution of the machine tool by the debris and the harm to the staff.

[0008] In a preferred solution, a motor frame is fixedly connected to the bottom of the machine tool away from the mounting plate. And a forward and reverse motor is fixedly connected to both ends of the motor frame. The output shafts of the two forward and reverse motors are fixedly connected with rotating shafts through couplings. Rotating brushes are fixedly connected to the outer side walls of the two rotating shafts.

[0009] In a preferred solution, air spraying pipes are fixedly connected to the outer side walls of the two rotating shafts. And air blowing holes are opened on the outer side walls of the air spraying pipes facing the lower oblique side of the rotating brushes. Machine ring frames are fixedly connected to the opposite sides of the two side dust suction plates. Air compressors are fixedly connected to the inside of the two machine ring frames. The air output ends of the air compressors are connected to the inside of the adjacent air spraying pipes through pipelines.

[0010] In a preferred embodiment, a shaft groove is formed at the top of the machine tool, and guide rollers are connected at equal intervals inside the shaft groove through bearings. Two adjustment chutes are formed at the top of the machine tool away from the guide rollers. Adjustment slide bars are slidably connected inside the two adjustment chutes, and the tops of the two adjustment slide bars are fixedly connected to the same clamping frame.

[0011] In a preferred embodiment, two hydraulic cylinders II are fixedly connected to the top of the clamping frame, and the output ends of the two hydraulic cylinders II are fixedly connected to the same positioning clamping plate. Two end plates are fixedly connected to the top of one end of the machine tool. Hydraulic cylinders III are fixedly connected to one side of the two end plates facing the clamping frame, and the output ends of the two hydraulic cylinders III are fixedly connected to one side of the clamping frame.

[0012] In a preferred embodiment, positioning slide rails are fixedly connected to both ends of the bottom of the machine tool, and positioning slide bars are slidably connected inside the two positioning slide rails. A moving push frame is fixedly connected to the opposite sides of the two positioning slide bars. An arc-shaped outer frame is fixedly connected to one side of the machine tool. A fixed plate is fixedly connected to the top of the arc-shaped outer frame. A hydraulic cylinder I is fixedly connected to one side of the fixed plate facing the moving push frame, and the output end of the hydraulic cylinder I is fixedly connected to one side of the moving push frame.

[0013] In a preferred embodiment, a fixed frame is fixedly connected to one side of the moving push frame, and a hydraulic cylinder IV is fixedly connected to the top of the fixed frame. A lifting chute is formed on one side of the moving push frame, and a lifting slider is slidably connected inside the lifting chute. The output end of the hydraulic cylinder IV is fixedly connected to the top of the lifting slider. A shaft frame is fixedly connected to one side of the lifting slider facing the machine tool. A driving motor is fixedly connected to one side of the shaft frame. The output shaft of the driving motor is fixedly connected to a driving shaft through a coupling. One end of the driving shaft is connected to the inside of the shaft frame through a bearing. A cutting blade is fixedly connected to the outer side wall of the driving shaft. An outer protective cover is fixedly connected to the shaft frame at the outer side of the cutting blade.

[0014] In a preferred embodiment, a shock absorption component is provided at the outer protective cover. The shock absorption component includes a fitting pressing plate. Shock absorption spring rods are fixedly connected at equal intervals to the side wall of the fitting pressing plate facing the cutting blade. One ends of the multiple shock absorption spring rods are fixedly connected to the same fitting outer ring piece, and the fitting outer ring piece is in contact with the outer side wall of the outer protective cover. A positioning hole is formed at the top of the lifting slider, and a docking rod is inserted into the positioning hole. One end of the docking rod is fixedly connected to one side of the fitting pressing plate. Pressing pieces are fixedly connected at equal intervals to the other side of the outer protective cover, and each pressing piece is in contact with the upper surface of the fitting pressing plate. Lock blocks are connected to both ends of the outer protective cover through hinges, and lock holes are formed at both ends of the fitting pressing plate. The lock blocks are inserted into the lock holes.

[0015] By setting a shock-absorbing component, before cutting the aluminum sheet, the docking rod is inserted into the positioning hole, then the fitting pressure plate and the fitting outer ring are pressed onto the outside of the outer protective cover, and then the lock block is locked into the lock hole. At this time, the shock-absorbing spring rod is in a highly compressed state. When the driving motor drives the cutting blade to cut the aluminum sheet, the shock-absorbing spring rod greatly weakens the vibration generated during the cutting process, thereby reducing the damage caused by the vibration to the cutting blade. At the same time, the stability during the cutting process is improved.

[0016] In a preferred embodiment, both ends of the cutting blade are provided with close-fitting dust suction components, and the close-fitting dust suction components include two dust suction covers.

[0017] By setting a close-fitting dust suction component, when the cutting blade cuts the aluminum sheet, the dust suction pump II is started. The dust suction pump II collects the debris generated during the cutting process through the dust suction holes II on the dust suction covers. At the same time, as the cutting blade moves, the bristles under the brush plate contact the upper surface of the aluminum sheet under the action of the self-adjusting spring rod, and the bristles drive the debris attached to the upper surface of the aluminum sheet, thereby improving the collection efficiency of the debris generated during the cutting process.

[0019] As can be seen from the above, a numerically controlled cutting device with a dust suction structure for aluminum sheet processing provided by the present invention has the following technical effects: after the aluminum sheet is cut, the second hydraulic cylinder drives the positioning clamping plate to release the clamping of one end of the cut aluminum sheet, then the aluminum sheet slides downward along the inclined guide plate at the clamping frame. When the aluminum sheet falls onto the lower blanking plate, the weight of the aluminum sheet impacts the blanking plate, causing the first shock spring rod to be in a shock state, thereby realizing the preliminary shock cleaning of the aluminum sheet. As the aluminum sheet slides down, it is squeezed against each contact arc block, and the second shock spring rod drives the aluminum sheet to perform secondary shock cleaning. At the same time, the first dust suction pump is started, and the first dust suction pump collects the dropped aluminum slag through the first dust suction holes on the two side dust suction plates, ensuring that the debris attached to the cut aluminum sheet is completely separated, improving the dust suction effect of the numerically controlled cutting device, and avoiding the pollution of the debris to the machine tool and the harm to the staff.

Detailed implementation manners

[0031] 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.

[0032] A numerically controlled cutting device with a dust suction structure for aluminum sheet processing disclosed by the present invention is mainly applied to the existing numerically controlled cutting device for aluminum sheet processing. During the use process, in order to avoid the pollution of the workbench caused by the debris generated during the cutting of the aluminum sheet, usually a dust suction structure is installed outside the cutting machine, and the debris generated during the cutting process is collected through this dust suction structure. However, during the cutting process of the aluminum sheet, a large amount of debris adheres to its inside and outside, and the dust suction structure cannot collect all of this part of the debris, and there is a scenario where part of the debris is retained on the workbench when the cut aluminum sheet moves on the workbench.

[0033] Referring to Figures 1-10 , a numerically controlled cutting device with a dust suction structure for aluminum sheet processing, including a machine tool 1. Four corners of the bottom of the machine tool 1 are fixedly connected with grounding seats 16, and a blanking hole is opened at the top of the middle part of the machine tool 1. A blanking dust suction assembly 15 is arranged below the blanking hole of the machine tool 1. The blanking dust suction assembly 15 includes a blanking plate 1501, and a plurality of shock spring rods 1505 are fixedly connected to the top of the blanking plate 1501 at equal intervals. The tops of the plurality of shock spring rods 1505 are fixedly connected to the same mounting plate 1504, and the mounting plate 1504 is fixedly connected to the bottom of the machine tool 1. A plurality of shock spring rods 1515 are fixedly connected to the inclined surface of the blanking plate 1501 at equal intervals, and one end of each shock spring rod 1515 is fixedly connected with a contact arc block 1514. A through hole is opened at the top of the blanking plate 1501 between every two rows of contact arc blocks 1514. A diversion arc piece 1503 is fixedly connected to the outer side wall of the bottom end of the blanking plate 1501. Side dust suction plates 1502 are fixedly connected to both sides of the blanking plate 1501, and dust suction holes 1511 are opened on the opposite sides of the two side dust suction plates 1502. The two side dust suction plates 1502 penetrate through the upper and lower surfaces of the blanking plate 1501. Connecting holes are opened on the opposite sides of the two side dust suction plates 1502, and the same connecting pipe 1513 is fixedly connected inside the two connecting holes. One side of the two grounding seats 16 is fixedly connected with the same dust suction box 14. A dust suction pump 18 is fixedly connected to the top of the dust suction box 14. The dust suction end of the dust suction pump 18 is inserted into the inside of the connecting pipe 1513 through a pipeline, and the dust conveying end of the dust suction pump 18 is connected to the inside of the dust suction box 14 through a pipeline.

[0034] In a specific application scenario, after the aluminum sheet is cut, the hydraulic cylinder 7 drives the positioning clamping plate 10 to release the clamping of one end of the cut aluminum sheet, then the aluminum sheet slides down along the inclined guide plate at the clamping frame 9. When the aluminum sheet falls onto the lower blanking plate 1501, the weight of the aluminum sheet impacts the blanking plate 1501, causing the shock spring rod 1505 to be in a shock state, thereby realizing the preliminary shock impurity removal of the aluminum sheet. As the aluminum sheet slides down, it is squeezed with each contact arc block 1514, and the shock spring rod 1515 drives the aluminum sheet to perform secondary shock impurity removal. At the same time, the dust suction pump 18 is started, and the dust suction pump 18 collects the dropped aluminum slag through the dust suction holes 1511 on the two side dust suction plates 1502, ensuring that the debris attached to the cut aluminum sheet is completely separated, improving the dust suction effect of the numerically controlled cutting device, and avoiding the pollution of the machine tool 1 by the debris and the harm to the staff.

[0035] Specifically, during the process of cutting the aluminum sheet, the forward and reverse motor 1510 and the air compressor 1506 are started. The forward and reverse motor 1510 drives the rotary brush 1508 to rotate 90°, thereby brushing off the debris attached to the falling aluminum sheet. The air compressor 1506 introduces compressed gas into the air injection pipe 1516 and sprays it through the air holes 1517. The spraying direction of the gas is obliquely downward, accelerating the separation of the debris from the aluminum sheet and further improving the collection effect of the debris inside and outside the aluminum sheet.

[0036] Refer to Figures 1-5 In a preferred embodiment, a motor frame 1509 is fixedly connected to the bottom of the machine tool 1 away from the mounting plate 1504, and forward and reverse motors 1510 are fixedly connected to both ends of the motor frame 1509. The output shafts of the two forward and reverse motors 1510 are fixedly connected to rotating shafts 1507 through couplings. Rotary brushes 1508 are fixedly connected to the outer side walls of the two rotating shafts 1507, and air injection pipes 1516 are fixedly connected to the outer side walls of the two rotating shafts 1507. Air holes 1517 are formed in the outer side walls of the air injection pipes 1516 facing the rotary brushes 1508 obliquely downward. Machine ring frames 1512 are fixedly connected to the opposite sides of the two side dust suction plates 1502, and air compressors 1506 are fixedly connected to the interiors of the two machine ring frames 1512. The air delivery ends of the air compressors 1506 are connected to the interiors of the adjacent air injection pipes 1516 through pipelines.

[0037] Refer to Figure 1 and Figure 2 In a preferred embodiment, a shaft groove is formed at the top of the machine tool 1, and guide rollers 2 are equidistantly connected to the interior of the shaft groove through bearings. Two adjustment chutes 11 are formed at the top of the machine tool 1 away from the guide rollers 2. Adjustment sliders 13 are slidably connected to the interiors of the two adjustment chutes 11. The tops of the two adjustment sliders 13 are fixedly connected to the same clamping frame 9. Two hydraulic cylinders II 7 are fixedly connected to the top of the clamping frame 9, and the output ends of the two hydraulic cylinders II 7 are fixedly connected to the same positioning clamping plate 10. Two end plates 12 are fixedly connected to the top of the machine tool 1 at one end, and hydraulic cylinders III 8 are fixedly connected to the sides of the two end plates 12 facing the clamping frame 9. The output ends of the two hydraulic cylinders III 8 are fixedly connected to one side of the clamping frame 9.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7, in a preferred embodiment, positioning slide rails 19 are fixedly connected to both ends of the bottom of the machine tool 1, and positioning slide bars 20 are slidably connected inside the two positioning slide rails 19. The opposite sides of the two positioning slide bars 20 are fixedly connected to the same moving push frame 17. An arc-shaped outer frame 3 is fixedly connected to one side of the machine tool 1. A fixed plate 4 is fixedly connected to the top of the arc-shaped outer frame 3. A first hydraulic cylinder 5 is fixedly connected to the side of the fixed plate 4 facing the moving push frame 17. The output end of the first hydraulic cylinder 5 is fixedly connected to one side of the moving push frame 17. A fixed frame 22 is fixedly connected to one side of the moving push frame 17, and a fourth hydraulic cylinder 23 is fixedly connected to the top of the fixed frame 22. A lifting chute 28 is formed on one side of the moving push frame 17, and a lifting slider 26 is slidably connected inside the lifting chute 28. The output end of the fourth hydraulic cylinder 23 is fixedly connected to the top of the lifting slider 26. A shaft frame 27 is fixedly connected to the side of the lifting slider 26 facing the machine tool 1. A driving motor 30 is fixedly connected to one side of the shaft frame 27. The output shaft of the driving motor 30 is fixedly connected to a driving shaft through a coupling. One end of the driving shaft is connected to the inside of the shaft frame 27 through a bearing. A cutting blade 31 is fixedly connected to the outer sidewall of the driving shaft. An outer protective cover 24 is fixedly connected to the shaft frame 27 at a position outside the cutting blade 31.

[0039] Referring to Figure 1 , Figure 6 and Figure 8 , in a preferred embodiment, a shock absorption assembly 6 is provided at the outer protective cover 24. The shock absorption assembly 6 includes a fitting pressure plate 601. Shock absorption spring rods 603 are equidistantly fixedly connected to the sidewall of the fitting pressure plate 601 facing the cutting blade 31. One ends of the multiple shock absorption spring rods 603 are fixedly connected to the same fitting outer ring 606. The fitting outer ring 606 is in contact with the outer sidewall of the outer protective cover 24. A positioning hole is formed in the top of the lifting slider 26, and a docking rod 604 is inserted into the positioning hole. One end of the docking rod 604 is fixedly connected to one side of the fitting pressure plate 601. Pressing pieces 602 are equidistantly fixedly connected to the other side of the outer protective cover 24. Each pressing piece 602 is in contact with the upper surface of the fitting pressure plate 601. Lock blocks 605 are hinged to both ends of the outer protective cover 24. Lock holes are formed at both ends of the fitting pressure plate 601, and the lock blocks 605 are inserted into the lock holes.

[0040] It should be noted that before cutting the aluminum sheet, the docking rod 604 is inserted into the positioning hole, then the fitting pressure plate 601 and the fitting outer ring 606 are pressed onto the outside of the outer protective cover 24, and then the lock blocks 605 are locked into the lock holes. At this time, the shock absorption spring rods 603 are in a highly compressed state. When the driving motor 30 drives the cutting blade 31 to cut the aluminum sheet, the shock absorption spring rods 603 greatly weaken the vibration generated during the cutting process, thereby reducing the damage caused by the vibration to the cutting blade 31. At the same time, the stability during the cutting process is improved.

[0041] Reference Figure 1 、 Figure 6 、 Figure 9 and Figure 10 In a preferred embodiment, close - type dust - suction assemblies 29 are provided at both ends of the cutting blade 31. The close - type dust - suction assembly 29 includes two dust - suction covers 2901. Extension rods 2906 are fixedly connected to both sides of the lifting slider 26. Mounting rods 2904 are fixedly connected to the ends of the two extension rods 2906. The dust - suction cover 2901 is fixedly connected to one end of the mounting rod 2904. Dust - suction holes II 2902 are formed in the outer side walls of the two dust - suction covers 2901 facing the lower part of the cutting blade 31. A dust - suction box II 21 is fixedly connected to one side of the moving push - frame 17. A dust - suction pump II 25 is fixedly connected to the top of the dust - suction box II 21. Communication holes are formed in the opposite sides of the two dust - suction covers 2901, and the same communication pipe 2905 is inserted into the communication holes. The dust - suction end of the dust - suction pump II 25 is inserted into the communication pipe 2905 through a pipeline, and the dust - conveying end of the dust - suction pump II 25 is connected to the inside of the dust - suction box II 21 through a pipeline. Self - adjusting spring rods 2907 are fixedly connected to the top of the dust - suction cover 2901 at equal intervals. A surrounding rod frame 2903 is fixedly connected to the tops of the plurality of self - adjusting spring rods 2907. A brush plate 2909 is fixedly connected to the bottom of the surrounding rod frame 2903, and bristles 2908 are provided at the bottom of the brush plate 2909.

[0042] Specifically, when the cutting blade 31 cuts the aluminum sheet, the dust - suction pump II 25 is started. The dust - suction pump II 25 collects the debris generated during the cutting process through the dust - suction holes II 2902 on the dust - suction cover 2901. At the same time, as the cutting blade 31 moves, the bristles 2908 under the brush plate 2909 contact the upper surface of the aluminum sheet under the action of the self - adjusting spring rods 2907, and the debris attached to the upper surface of the aluminum sheet is driven by the bristles 2908, thereby improving the collection efficiency of the debris generated during the cutting process.

[0043] Working principle: When in use, push the aluminum sheet to the clamping frame 9, adjust the hydraulic cylinder II 7 to drive the positioning clamping plate 10 to clamp one end of the aluminum sheet, start the driving motor 30, adjust the hydraulic cylinder I 5 and the hydraulic cylinder IV 23 to drive the cutting blade 31 to cut the aluminum sheet. During the cutting process, start the dust suction pump II 25, and the dust suction pump II 25 collects the debris generated during the cutting process through the dust suction holes II 2902 on the dust suction cover 2901. At the same time, as the cutting blade 31 moves, the bristles 2908 under the brush plate 2909 contact the upper surface of the aluminum sheet under the action of the self-adjusting spring rod 2907, and drive the debris attached to the upper surface of the aluminum sheet through the bristles 2908 to accelerate the collection of the debris. When the aluminum sheet cutting is completed, the cutting blade 31 resets, and the hydraulic cylinder II 7 drives the positioning clamping plate 10 to release the clamping of one end of the cut aluminum sheet, then the aluminum sheet slides downward along the inclined guide plate at the clamping frame 9. When the aluminum sheet falls onto the lower blanking plate 1501, the weight of the aluminum sheet impacts the blanking plate 1501, causing the shock spring rod I 1505 to be in a shock state, thereby realizing the preliminary shock impurity removal of the aluminum sheet. As the aluminum sheet slides down, it is squeezed against each contact arc block 1514, and the shock spring rod II 1515 drives the aluminum sheet for secondary shock impurity removal. Start the dust suction pump I 18, and the dust suction pump I 18 collects the dropped aluminum slag through the dust suction holes I 1511 on the two side dust suction plates 1502. At the same time, start the forward and reverse motor 1510 and the air compressor 1506. The forward and reverse motor 1510 drives the rotary brush 1508 to rotate 90°, so as to brush off the debris attached to the falling aluminum sheet. The air compressor 1506 introduces the compressed gas into the air injection pipe 1516 and sprays it out through the air injection holes 1517. The spraying direction of the gas is obliquely downward to accelerate the separation of the debris from the aluminum sheet. When the aluminum sheet falls through the lowest drainage arc piece 1503, the staff collects it and ends the operation.
