Description

Technical Field

[0001] The present invention belongs to the technical field of machining of mechanical parts, and specifically relates to an automatic loading and unloading laser cutting device for flange production. Background Art

[0002] In the machining industry of mechanical parts, it is often necessary to use a laser cutter or a laser cutting gun to cut out the shape of a flange on a metal plate, and then remove the inner ring material of the flange to complete the preparation of the flange.

[0003] A patent with the publication number CN119016903B discloses an automatic loading and unloading profile laser cutting device. Through the coordinated design of a protective component, a waste collection component, and a positioning and cleaning component, when the bottom cover touches the surface of the profile, the exhaust fan connected to the connecting pipe starts. The continuous airflow sequentially passes through the micropores on the side wall of the bottom cover, the top cover, the exhaust valve, the air cavity of the air pipe, the air delivery hose, and the receiving tray, then passes through the filter cover and is discharged through the connecting pipe. This causes the air cavities of the left and right air pipes and the buffer cavities communicated with them to form a negative pressure, causing the left and right piston rods to gradually withdraw from the buffer cavities and compress the springs to converge inward. The piston rods carry the T-shaped frame and the electric clamp to gradually approach the profile to achieve stable clamping of the profile. Then, the cutting inclination angle is adjusted by an angle adjuster. Finally, the laser beam generated by the laser cutting gun cuts the profile. The metal chips generated by the cutting cannot escape from the bottom cover and are transported to the hopper through the flowing high-pressure airflow for centralized storage. During the above telescopic movement of the piston rod, the brush plate connected to its end will be driven to reciprocate, pushing the leaked chips accumulated on the bottom wall of the receiving tray to make them close to the material dropping port, reducing the accumulation rate of the leaked chips in the receiving tray and maintaining the efficient and sustainable operation of the device.

[0004] The above solution still has some problems in actual application. Usually, an alloy steel plate is placed on the workbench, and then the mechanical arm is used to drive the laser cutter to approach and fit the alloy steel plate. At the same time, the laser cutter is started to cut out the inner ring of the flange on the alloy steel plate, and then the outer contour of the flange is cut. However, since a large amount of waste residues generated by laser heating and vaporization are produced during cutting and accumulate in the workbench for a long time, the waste residues of laser heating and vaporization will stick and agglomerate with each other. If they are not cleaned in time, the waste residues will affect the penetrability of the laser cutter. Moreover, after the flange is cut, it is necessary to separate and recycle the alloy steel plate, the flange, and the waste materials, which not only makes the operation cumbersome but also affects the production efficiency of the flange.

[0005] Therefore, the present invention provides an automatic loading and unloading laser cutting device for flange production. Summary of the Invention

[0012] Preferably, a U-shaped fixing frame is installed at one end of the rotating rod. An anti-slip rubber pad is arranged in the inner cavity of the U-shaped fixing frame, and the U-shaped fixing frame cooperates with the rotating rod to fixedly install laser cutters of different models and sizes.

[0013] Preferably, a second motor is installed on one side of the upper end surface of the support plate. The output shaft end of the second motor is fixedly connected with a transmission gear, and the transmission gear is meshed with the toothed ring.

[0014] Preferably, a mounting frame is installed on the upper end of the support plate. A first motor is installed on the upper end of the mounting frame.

[0016] Preferably, a rotating groove is formed inside the T-shaped fixing block. A rotating shaft is rotatably connected to the inner cavity of the rotating groove.

[0017] The beneficial effects of the present invention are as follows: 1. For the automatic loading and unloading laser cutting equipment for flange production of the present invention, the flange cut by laser will fall onto the bracket. Then, the weight of the flange itself presses the bracket to move downward. At the same time, the bracket drives the dial block to abut and flip with the abutting block, thereby guiding the flange on the bracket into the inner cavity of the recovery port for discharging and collecting. After the flange is discharged into the inner cavity of the recovery port, the second torsion spring twists the rotating disc to flip and reset. At the same time, the rotating disc drives the dial block and the bracket to rotate and reset. Then, the spring bounces the sliding disc upward to move and reset, thereby enabling the bracket to clean the waste slag generated by laser cutting in the inner cavity of the slag discharge port, preventing the waste slag from accumulating in the inner cavity of the slag discharge port for a long time and causing the situation of cooling and caking, so as to realize the cyclic collection and transportation of the flange and the cleaning work of the waste slag generated by laser cutting of the alloy steel plate in the slag discharge port, and improve the production efficiency of the flange.

[0018] 2. The automatic loading and unloading laser cutting equipment for flange production according to the present invention drives the driving gear disk to slide between two gears for meshing, then starts the first motor to drive the electric push rod and the gear disk to rotate, and makes the gear disk drive the transmission gear to rotate through meshing, thereby driving the rotating rod to rotate. At the same time, the rotating rod drives the U-shaped fixing bracket and the laser cutter to rotate to adjust the inner diameter, so as to adjust the cutting position according to different sizes of flanges, and then starts the electric push rod to drive the gear disk to move upward to disengage from the gear. At the same time, it drives the gear ring to rotate, and makes the gear ring drive the gear to rotate, thereby driving the rotating rod and the laser cutter to rotate, so as to use the laser cutter to cut and process the alloy steel plate to produce flanges. Furthermore, the position of the laser cutter can be quickly adjusted according to different sizes of flanges, so that the laser cutter can quickly cut the alloy steel plate to produce flanges.

[0019] 3. The automatic loading and unloading laser cutting equipment for flange production according to the present invention drives the T-shaped fixing block to move downward through the support plate, and makes the T-shaped fixing block drive the rotating frame to move downward. At the same time, the rotating frame drives the loading column to move downward, so that the loading column pushes the alloy steel plate to move towards the tail of the workbench. At the same time, it drives the alloy steel plate at the complete part to move under the support plate for cutting and processing to prepare flanges, thereby realizing the automatic loading of the alloy steel plate and improving the cutting and processing efficiency of flanges. When the support plate moves upward and resets, the first torsion spring will twist the fixed disk to rotate and reset. At the same time, the fixed disk drives the rotating shaft to rotate, and then drives the rotating frame to rotate and reset, waiting for the next cutting and processing of flanges, thereby realizing the cyclic loading and unloading and conveying of the alloy steel plate and improving the laser cutting preparation efficiency of flanges.

Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 9 shown, an automatic loading and unloading laser cutting device for flange production described in an embodiment of the present invention includes a workbench 1. A slag discharge port 20 is opened on one side of the upper end of the workbench 1, and a recovery port 21 is opened on one side of the lower end of the workbench 1. The recovery port 21 is arranged in an inverted right-angled triangle and is communicated with the inner cavity of the slag discharge port 20. A blanking and cleaning assembly 9 is arranged in the inner cavity of the slag discharge port 20, and a loading and cutting assembly 8 is arranged above the slag discharge port 20 for cutting an alloy steel plate 3 to process a flange; The blanking and cleaning assembly 9 includes two chutes 91 opened on the inner wall of the slag discharge port 20. Springs 96 are fixedly connected to the bottom of the inner cavities of the two chutes 91. One end of each spring 96 is fixedly connected to a sliding disc 94. Shifting blocks 93 are rotatably connected to the mutually close ends of the sliding discs 94, and a bracket 92 is fixedly connected between the shifting blocks 93; Abutting blocks 97 are installed on the inner walls of the chutes 91. The bracket 92 is used to hold the flange cut by laser cutting. At the same time, the self-weight of the flange presses the spring 96 to move downward, and the bracket 92 drives the shifting block 93 to move downward and abut against the abutting block 97 to flip, so as to introduce the flange into the inner cavity of the recovery port 21 for discharge and collection.

[0024] Specifically, in the prior art, an alloy steel plate is usually placed on a workbench, and then a robotic arm is used to drive a laser cutter to approach and fit the alloy steel plate. At the same time, the laser cutter is started to cut the inner ring of the flange on the alloy steel plate, and then the outer contour of the flange is cut. However, since a large amount of waste residue generated by laser heating and vaporization is produced during cutting and accumulates in the workbench for a long time, the waste residue of laser heating and vaporization will stick together and form lumps. If it is cleaned in time, the waste residue will affect the penetrability of the laser cutter. Moreover, after the flange is cut and processed, it is necessary to separate and recycle the alloy steel plate, the flange, and the waste material, which not only makes the operation cumbersome but also affects the production efficiency of the flange. When the present invention manufactures the flange, the alloy steel plate 3 is placed on the workbench, and at the same time, the feeding and cutting assembly 8 is driven to move downward, and the feeding and cutting assembly 8 is started to operate to cut the through hole in the middle of the flange on the alloy steel plate 3. The waste material generated by cutting will fall into the slag discharge port 20 and be discharged and collected through the hollow part of the bracket 92. Then, the alloy steel plate 3 is cut again by the feeding and cutting assembly 8 to cut out the flange, thereby realizing the cutting and processing of the flange. The cut flange will fall onto the bracket 92 in the slag discharge port 20. At the same time, the weight of the flange itself is used to press down the bracket 92, and the bracket 92 drives the sliding plate 94 to slide in the inner cavity of the sliding groove 91. At the same time, the sliding plate 94 squeezes the spring 96 to move downward. After the bracket 92 drives the dial block 93 to move downward by two-thirds of the process, the dial block 93 will abut against the abutting block 97, and at the same time, the dial block 93 will flip and drive the bracket 92 to rotate. At this time, the flange will slide off the bracket 92 and enter the inner cavity of the recovery port 21. Then, a recovery box is arranged below the recovery port 21 to catch the flange falling out of the inner cavity of the recovery port 21 for collection. A brush is arranged outside the bracket 92. During the downward movement of the bracket 92 and the process of rebounding and resetting through the spring 96, the bracket 92 will use the external brush to scrape and clean the laser cutting waste residue on the inner wall of the slag discharge port 20, avoiding the situation that the waste residue generated by laser cutting is not cleaned for a long time and hardens and adheres into a whole block, affecting the subsequent cutting and processing of the flange and the discharge and recovery of the waste material, thereby solving the above problems.

[0025] As Figures 3 to 6 shown, a limiting post 95 is fixedly connected to the inner cavity of the sliding groove 91, and the sliding plate 94 is slidably connected to the outside of the limiting post 95. A rotating disk 98 is fixedly connected to the outside of the inner cavity of the sliding plate 94 where the dial block 93 is located. A second torsion spring 99 is fixedly connected to one side of the rotating disk 98, and one end of the second torsion spring 99 is fixedly connected to the inner wall of the sliding plate 94.

[0026] Specifically, the flange cut by laser will fall onto the bracket 92. Then, due to the weight of the flange itself, the bracket 92 is pressed downward to move, and at the same time, the bracket 92 drives the dial 93 to press against the abutting block 97 for the abutting block to flip, thereby guiding the flange on the bracket 92 into the inner cavity of the recovery port 21 for discharge and collection. After the flange is discharged into the inner cavity of the recovery port 21, the second torsion spring 99 twists the rotating disk 98 to flip and reset, and at the same time, the rotating disk 98 drives the dial 93 and the bracket 92 to rotate and reset. Then, the spring 96 bounces the sliding disk 94 upward to reset, thus realizing the cyclic collection and transportation of the flange, and cleaning the waste generated by laser cutting of the alloy steel plate 3 in the inner cavity of the slag discharge port 20, improving the production efficiency of the flange, and solving the problem that in the existing automatic loading and unloading laser cutting equipment for flange production, when cutting and processing the alloy steel plate to prepare the flange, it is inconvenient to automatically collect the cut flange, resulting in low production efficiency of the flange, and it is difficult to clean the waste generated by laser cutting, leading to the gasified waste generated by laser cutting cooling and caking for a long time, making it difficult to clean in the later stage.

[0027] As Figure 1 and Figure 2 shown, a limiting frame 2 is installed at one end of the workbench 1. A plurality of rollers 22 are rotatably connected in the inner cavity of the limiting frame 2. An alloy steel plate 3 is placed in the inner cavity of the limiting frame 2 for limiting the alloy steel plate 3.

[0028] As Figure 1 、 Figures 7 to 9 shown, four grooves 4 are opened at both ends of the workbench 1, and the four grooves 4 are arranged in groups of two at both ends of the workbench 1. A threaded rod 5 is rotatably connected in the inner cavity of the groove 4. A slider 6 is threadedly connected to the outside of the threaded rod 5. One end of the slider 6 is rotatably connected to a support rod 7. One end of the support rod 7 is rotatably connected to the loading and cutting assembly 8 for driving the loading and cutting assembly 8 to move downward to fit with the alloy steel plate 3 for cutting and processing. And a servo motor is arranged inside the workbench 1, and the output shaft end of the servo motor is fixedly connected to the threaded rod 5.

[0029] Specifically, when cutting the alloy steel plate 3 to prepare the flange, by driving the threaded rod 5 to rotate, and making the threaded rod 5 threadedly drive the slider 6 to slide away from each other in the inner cavity of the groove 4, thereby making the slider 6 drive the support rod 7 to rotate, and making the support rod 7 drive the loading and cutting assembly 8 to move downward, so that the loading and cutting assembly 8 approaches and fits with the alloy steel plate 3. Then, start the laser cutting mechanism to cut the alloy steel plate 3 to cut out the flange and cut off the waste inside the flange, thus completing the preparation work of the flange.

[0030] As Figure 1 、 Figures 7 to 9As shown in the figure, the loading and cutting assembly 8 includes a support plate 81 installed at one end of the support rod 7. A gear ring 82 is rotatably connected inside the support plate 81. A gear 84 is rotatably connected inside the gear ring 82. A rotating rod 85 is fixedly connected to the lower end of the gear 84. A laser cutter 87 is installed at one end of the rotating rod 85.

[0031] As Figures 7 to 9 shown in the figure, a U-shaped fixing frame 86 is installed at one end of the rotating rod 85. An anti-slip rubber pad is arranged inside the U-shaped fixing frame 86. The U-shaped fixing frame 86 and the rotating rod 85 cooperate to fixedly install laser cutters 87 of different models and sizes.

[0032] As Figure 1 、 Figures 7 to 9 shown in the figure, a second motor 12 is installed on one side of the upper end surface of the support plate 81. A transmission gear 88 is fixedly connected to the output shaft end of the second motor 12. The transmission gear 88 is meshed with the gear ring 82.

[0033] Specifically, when the support rod 7 drives the support plate 81 to move downward, the support plate 81 will drive the gear ring 82 to move downward. At the same time, the gear ring 82 drives the gear 84 to move downward, and the gear 84 drives the rotating rod 85 to move downward. Further, the rotating rod 85 cooperates with the U-shaped fixing frame 86 to drive the laser cutter 87 to move synchronously. Then, the laser cutter 87 approaches the alloy steel plate 3 on the workbench 1. At the same time, the laser cutter 87 is started to operate, and the second motor 12 is started to drive the transmission gear 88 to rotate. Then, the transmission gear 88 meshes with and drives the gear ring 82 to rotate, and drives the gear 84 to rotate. Subsequently, the rotating rod 85 is driven to rotate. At the same time, the rotating rod 85 cooperates with the U-shaped fixing frame 86 to drive the laser cutter 87 to rotate. Further, when the laser cutter 87 rotates, the alloy steel plate 3 is cut to produce a flange and the waste material inside the flange. Moreover, with the arrangement of two laser cutters 87, only by driving the gear ring 82 to rotate 180 degrees, the flange can be quickly cut, thereby improving the cutting and processing efficiency of the flange. Thus, it solves the problem that when the existing automatic loading and unloading laser cutting equipment for flange production cuts and processes the alloy steel plate to prepare a flange, since the laser cutter is usually controlled by a robotic arm to cut the alloy steel plate, not only does the robotic arm need to accurately control the laser cutter to cut out the outer circular contour of the flange, but also the redundant material inside the flange needs to be removed, resulting in cumbersome operation and affecting the cutting and preparation efficiency of the flange.

[0034] Embodiment 2: As Figure 1 、 Figures 7 to 9 shown in the figure, an installation frame 10 is installed on the upper end of the support plate 81. A first motor 11 is installed on the upper end of the installation frame 10. An electric push rod is fixedly connected to the output shaft end of the first motor 11. The piston rod end of the electric push rod is fixedly connected to a toothed disc 83. The toothed disc 83 is meshed with the gear 84.

[0035] Specifically, when cutting and preparing flanges of different models, the electric push rod is started to drive the gear disc 83 to move downward, and the gear disc 83 slides into the space between the two gears 84 for meshing. Then, the first motor 11 is started to drive the electric push rod and the gear disc 83 to rotate, and the gear disc 83 meshes with and drives the transmission gear 84 to rotate, thereby driving the rotating rod 85 to rotate. At the same time, the rotating rod 85 drives the U-shaped fixing bracket 86 and the laser cutter 87 to rotate to adjust the inner diameter, so as to adjust the cutting position according to flanges of different model sizes. Then, the electric push rod is started to drive the gear disc 83 to move upward to disengage from the gear 84, and at the same time, the gear ring 82 is driven to rotate, and the gear ring 82 drives the gear 84 to rotate, thereby driving the rotating rod 85 and the laser cutter 87 to rotate. Thus, the alloy steel plate 3 is cut by the laser cutter 87 to process the flange, which solves the problem that when the existing automatic loading and unloading laser cutting equipment for flange production cuts and prepares the flange, it is inconvenient to adjust the position of the laser cutter according to flanges of different model sizes, so that the laser cutter can quickly cut the alloy steel plate to produce the flange, resulting in low efficiency of flange cutting and preparation. When using a robotic arm to control the laser cutter to cut and prepare flanges of different models, a large amount of time is wasted for adjustment, which is not only cumbersome to operate but also affects the preparation efficiency of the flange.

[0036] As Figures 7 to 9 shown, a T-shaped fixing block 13 is installed on one side of the support plate 81. Rotating frames 14 are rotatably connected to both ends of the T-shaped fixing block 13. A loading column 15 is installed between the rotating frames 14. A number of rubber teeth are annularly arranged on the outer part of the loading column 15.

[0037] As Figures 7 to 9 shown, a rotating groove 16 is formed inside the T-shaped fixing block 13. A rotating shaft 19 is rotatably connected to the inner cavity of the rotating groove 16. Both ends of the rotating shaft 19 are fixedly connected to the rotating frames 14. A fixing disc 18 is installed outside the inner cavity of the rotating groove 16 on the rotating shaft 19. A first torsion spring 17 is fixedly connected to one side of the fixing disc 18, and one end of the first torsion spring 17 is fixedly connected to the inner wall of the rotating groove 16.

[0038] Specifically, when driving the support plate 81 to move downward, the T-shaped fixing block 13 is driven to move downward by the support plate 81, and the rotating frame 14 is driven to move downward by the T-shaped fixing block 13. At the same time, the feeding column 15 is driven to move downward by the rotating frame 14. A number of rubber tooth blocks are arranged outside the feeding column 15. Therefore, during the downward movement of the feeding column 15, the feeding column 15 will abut against the alloy steel plate 3. Then, as the support plate 81 continues to move downward, the T-shaped fixing block 13 will drive the rotating frame 14 to move downward. At the same time, the rotating frame 14 drives the feeding column 15 to push the alloy steel plate 3 towards the tail of the workbench 1, thereby driving the alloy steel plate 3 of the complete part to move under the support plate 81 for cutting and processing to prepare the flange, thus realizing the automatic feeding of the alloy steel plate 3 and improving the cutting and processing efficiency of the flange. When the support plate 81 moves upward and resets, the first torsion spring 17 will twist and the fixed disk 18 will rotate and reset. At the same time, the fixed disk 18 drives the rotating shaft 19 to rotate, and then drives the rotating frame 14 to rotate and reset, thus waiting for the next cutting and processing of the flange, solving the problem that in the existing automatic loading and unloading laser cutting equipment for flange production, when laser cutting the alloy steel plate to prepare the flange, due to the inconvenience of automatically loading and unloading the alloy steel plate, it is necessary for workers or robotic arms to clamp, recycle, and load the alloy steel plate each time, resulting in low laser cutting and processing efficiency of the flange.

[0039] Working principle: When manufacturing the flange, the alloy steel plate 3 is placed on the workbench. At the same time, the feeding and cutting assembly 8 is driven to move downward, and the feeding and cutting assembly 8 is started to operate to cut the through hole in the middle of the alloy steel plate 3. The waste generated by the cutting will fall into the slag discharge port 20 and be discharged and collected through the hollow part of the bracket 92. Then, the alloy steel plate 3 is cut again by the feeding and cutting assembly 8, and then the flange is cut out, thus realizing the cutting and processing of the flange. The cut flange will fall onto the bracket 92 in the slag discharge port 20. At the same time, the weight of the flange itself is used to press down the bracket 92, and the bracket 92 drives the sliding disk 94 to slide in the inner cavity of the chute 91. At the same time, the sliding disk 94 squeezes the spring 96 to move downward. After the bracket 92 drives the dial block 93 to move downward by two-thirds of the process, the dial block 93 will abut against the abutting block 97, and at the same time, the dial block 93 will flip and drive the bracket 92 to rotate. At this time, the flange will slide off the bracket 92 and enter the inner cavity of the recovery port 21. Then, a recovery box is arranged below the recovery port 21, and the flange falling out of the inner cavity of the recovery port 21 will be caught and collected. A brush is arranged outside the bracket 92. During the downward movement of the bracket 92 and the process of rebounding and resetting through the spring 96, the bracket 92 will use the external brush to scrape and clean the laser cutting waste slag on the inner wall of the slag discharge port 20, avoiding the situation that the waste slag generated by laser cutting is not cleaned for a long time, resulting in cooling and hardening and sticking into a whole piece, affecting the subsequent cutting and processing of the flange and the discharge and recovery of the waste. When cutting and preparing flange plates of different models, the electric push rod is started to drive the gear disk 83 to move downward, and the gear disk 83 slides between the two gears 84 for meshing. Then, the first motor 11 is started to drive the electric push rod and the gear disk 83 to rotate, and the gear disk 83 drives the transmission gear 84 to rotate through meshing, thereby driving the rotating rod 85 to rotate. At the same time, the rotating rod 85 drives the U-shaped fixing bracket 86 and the laser cutter 87 to rotate to adjust the inner diameter, so as to adjust the cutting position according to flange plates of different model sizes. Then, the electric push rod is started to drive the gear disk 83 to move upward to disengage from the gear 84. At the same time, the gear ring 82 is driven to rotate, and the gear ring 82 drives the gear 84 to rotate, thereby driving the rotating rod 85 and the laser cutter 87 to rotate. Thus, the alloy steel plate 3 is cut and processed into flange plates by the laser cutter 87; When driving the support plate 81 to move downward, the support plate 81 drives the T-shaped fixing block 13 to move downward, and the T-shaped fixing block 13 drives the rotating frame 14 to move downward. At the same time, the rotating frame 14 drives the feeding column 15 to move downward. A number of rubber teeth are arranged outside the feeding column 15. Therefore, during the downward movement of the feeding column 15, the feeding column 15 will abut against the alloy steel plate 3. Then, as the support plate 81 continues to move downward, the T-shaped fixing block 13 drives the rotating frame 14 to move downward. At the same time, the rotating frame 14 drives the feeding column 15 to push the alloy steel plate 3 towards the tail of the workbench 1, thereby driving the alloy steel plate 3 at the complete part to move under the support plate 81 for cutting and processing to prepare flange plates, thus realizing the automatic feeding of the alloy steel plate 3 and improving the cutting and processing efficiency of flange plates. When the support plate 81 moves upward to reset, the first torsion spring 17 will twist to drive the fixed disk 18 to rotate and reset. At the same time, the fixed disk 18 drives the rotating shaft 19 to rotate, and then drives the rotating frame 14 to rotate and reset, thereby waiting for the next cutting and processing of flange plates, thus realizing the cyclic up and down feeding and conveying of the alloy steel plate 3 and improving the laser cutting efficiency of flange plates.
