Description

Technical Field

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

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

[0003] A patent with the announcement number CN119016903B discloses an automatic loading and unloading profile laser cutting device. The device is designed with 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 is started. The continuous air flow 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 hose and the receiving tray in sequence, and then passes through the filter cover and is discharged through the connecting pipe, so that the air cavities of the left and right air pipes and the buffer cavity connected thereto form a negative pressure, causing the left and right piston rods to gradually withdraw from the buffer cavity and compress the spring to move forward. The inner sides converge, and the piston rod carrying the T-shaped frame and the electric clamp gradually approaches the profile to achieve stable clamping of the profile. The cutting angle is then adjusted by the angle adjuster, and finally the laser beam generated by the laser cutting gun cuts the profile. The metal debris generated by the cutting cannot escape the bottom cover, but is transported to the hopper for centralized storage with the flow of high-pressure airflow. During the above-mentioned telescopic movement, the piston rod will drive the brush plate connected to its end to move back and forth, pushing the leaked debris accumulated on the bottom wall of the receiving tray to close to the drop port, reducing the accumulation rate of the leaked debris in the receiving tray, and maintaining the efficient and sustainable operation of the equipment.

[0004] The above scheme still has some problems in actual application. Usually, a piece of alloy steel plate is placed on the workbench, and then a robotic arm is used to drive the laser cutter close to the alloy steel plate. At the same time, the laser cutter is started to cut the inner circle of the flange from the alloy steel plate, and then the outer contour of the flange is cut. However, since a large amount of laser heated vaporized waste slag will be generated during cutting, it will accumulate on the workbench for a long time. The laser heated vaporized waste slag will stick to each other and clump together. If it is cleaned in time, the waste slag will affect the penetration of the laser cutter. Moreover, after the flange is cut, the alloy steel plate, the flange and the waste need to be separated and recycled, which is not only cumbersome to operate but also affects the production efficiency of the flange.

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

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1: Figures 1 to 9 As shown, an automatic loading and unloading laser cutting device for flange production according to 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, a recovery port 21 is opened on one side of the lower end of the workbench 1, and the recovery port 21 is arranged in an inverted right triangle and is connected to the inner cavity of the slag discharge port 20, a material unloading and cleaning component 9 is provided in the inner cavity of the slag discharge port 20, and a material loading and cutting component 8 is provided above the slag discharge port 20 for cutting the alloy steel plate 3 to process the flange;

[0036] The material cleaning assembly 9 includes two chutes 91 provided on the inner wall of the slag discharge port 20, and a spring 96 is fixedly connected to the bottom of the inner cavity of the two chutes 91. One end of the spring 96 is fixedly connected to a sliding plate 94. The sliding plates 94 are connected to each other at one end and rotated to connect to the shifting blocks 93. A bracket 92 is fixedly connected between the shifting blocks 93.

[0037] A stop block 97 is installed on the inner wall of the slide groove 91, and the bracket 92 is used to support the flange processed by laser cutting. At the same time, the spring 96 is pressed downward by the weight of the flange itself, and the bracket 92 drives the shift block 93 to move downward and abut against the stop block 97 to flip over, so that the flange can be introduced into the inner cavity of the recovery port 21 for discharge and collection.

[0038] 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 close to the alloy steel plate, and at the same time, the laser cutter is started to cut the inner ring of the flange from the alloy steel plate, and then the outer contour of the flange is cut. However, since a large amount of waste residue vaporized by laser heating is generated during cutting, it accumulates on the workbench for a long time. The waste residue vaporized by laser heating will stick to each other and clump together. If it is cleaned in time, the waste residue will affect the penetration of the laser cutter. Moreover, after the flange is cut, the alloy steel plate, the flange and the waste need to be separated and recycled, which is not only cumbersome but also affects the production efficiency of the flange.

[0039] When the flange is processed and manufactured by the present invention, the alloy steel plate 3 is placed on the workbench, and the feeding and cutting assembly 8 is driven to move downward, and the feeding and cutting assembly 8 is started to cut the alloy steel plate 3 to form a through-hole in the middle of the flange. The waste generated by the cutting will fall into the slag discharge port 20 and pass through the hollow part of the bracket 92 for discharge and collection. 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 processing of the flange. The cut flange will fall onto the bracket 92 in the slag discharge port 20, and 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 slide groove 91. At the same time, the sliding plate 94 squeezes the spring 96 to move downward, and the bracket 92 After the shift block 93 moves downward two-thirds of the way, the shift block 93 will abut against the abutment block 97, and the shift block 93 will flip over and drive the bracket 92 to rotate. At this time, the flange will slide from the bracket 92 into the inner cavity of the recovery port 21. Then, a recovery box is set under the recovery port 21 to catch the flange that falls out of the inner cavity of the recovery port 21 for collection. A brush is set on the outside of the bracket 92. When the bracket 92 moves downward and rebounds and resets through the spring 96, the bracket 92 will use the external brush to scrape and clean the laser cutting waste on the inner wall of the slag discharge port 20, so as to avoid the waste generated by laser cutting from being not cleaned for a long time, cooling and hardening and sticking into a whole piece, affecting the flange of the subsequent cutting processing and the discharge and recycling of waste materials, thereby solving the above-mentioned problem.

[0040] like Figures 3 to 6 As shown, the inner cavity of the slide groove 91 is fixedly connected to the limiting column 95, and the sliding plate 94 is slidably connected to the outside of the limiting column 95. The shift block 93 is located outside the inner cavity of the sliding plate 94 and is fixedly connected to the rotating plate 98. A second torsion spring 99 is fixedly connected to one side of the rotating plate 98, and one end of the second torsion spring 99 is fixedly connected to the inner wall of the sliding plate 94.

[0041] Specifically, the flange cut by the laser will fall onto the bracket 92, and then the weight of the flange will be used to press the bracket 92 downward. At the same time, the bracket 92 will drive the shift block 93 and the stop block 97 to flip the stop block, and then the flange on the bracket 92 will be introduced 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. At the same time, the rotating disk 98 drives the shift block 93 and the bracket 92 to rotate and reset, and then the spring 96 bounces the sliding disk 94 upward to reset. The present invention relates to a flange production line which is composed of a plurality of laser cutting machines, a plurality of laser cutting machines and a plurality of laser cutting machines which are used for cutting and processing alloy steel plates. The flange production line ...

[0042] like Figure 1 and Figure 2 As shown, a limiting frame 2 is installed at one end of the workbench 1, and a plurality of rollers 22 are rotatably connected to 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.

[0043] like Figure 1 、 Figures 7 to 9 As shown, four grooves 4 are provided 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. The inner cavity of the groove 4 is rotatably connected to a threaded rod 5, and the outer thread of the threaded rod 5 is threadedly connected to a slider 6. One end of the slider 6 is rotatably connected to a support rod 7, and one end of the support rod 7 is rotatably connected to a loading and cutting assembly 8, which is used to drive the loading and cutting assembly 8 to move downward and fit the alloy steel plate 3 for cutting processing. A servo motor is provided inside the workbench 1, and the output shaft end of the servo motor is fixedly connected to the threaded rod 5.

[0044] Specifically, when the alloy steel plate 3 is cut to prepare the flange, the threaded rod 5 is driven to rotate, and the threaded transmission slider 6 of the threaded rod 5 slides in the inner cavity of the groove 4 and moves away from each other, so that the slider 6 drives the support rod 7 to rotate, and the support rod 7 drives the loading and cutting assembly 8 to move downward, so that the loading and cutting assembly 8 is close to and fits with the alloy steel plate 3, and then the laser cutting mechanism is started to cut the flange from the alloy steel plate 3 and remove the waste material of the inner ring of the flange, thereby completing the preparation of the flange.

[0045] like Figure 1 、 Figures 7 to 9As shown, the loading and cutting assembly 8 includes a support plate 81 installed at one end of the support rod 7, the inner cavity of the support plate 81 is rotatably connected to a ring gear 82, the inner cavity of the ring gear 82 is rotatably connected to a gear 84, the lower end of the gear 84 is fixedly connected to a rotating rod 85, and one end of the rotating rod 85 is installed with a laser cutter 87.

[0046] like Figures 7 to 9 As shown, a U-shaped fixing frame 86 is installed at one end of the rotating rod 85, and an anti-slip rubber pad is provided in the inner cavity of the U-shaped fixing frame 86. The U-shaped fixing frame 86 cooperates with the rotating rod 85 to fix and install laser cutters 87 of different models and sizes.

[0047] like Figure 1 、 Figures 7 to 9 As shown, a second motor 12 is mounted 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 , and the transmission gear 88 is meshed with the ring gear 82 .

[0048] Specifically, when the support rod 7 drives the support plate 81 to move downward, the support plate 81 will drive the ring gear 82 to move downward, and at the same time, the ring gear 82 drives the gear 84 to move downward, and the gear 84 drives the rotating rod 85 to move downward, so that the rotating rod 85 cooperates with the U-shaped fixing frame 86 to drive the laser cutter 87 to move synchronously, and then the laser cutter 87 is brought close to the alloy steel plate 3 on the workbench 1, and the laser cutter 87 is started to run, and the second motor 12 is started to drive the transmission gear 88 to rotate, and then the transmission gear 88 is engaged with the transmission ring gear 82 to rotate, and drives the gear 84 to rotate, and then drives the rotating rod 85 to rotate, and at the same time, the rotating rod 85 cooperates with the U-shaped fixing frame 86 to drive the laser cutter 87 to rotate, so as to facilitate the rotation of the rotating rod 85. During the rotation process, the laser cutter 87 is used to cut the flange and the waste material of the inner ring of the flange from the alloy steel plate 3. Moreover, the setting of the two laser cutters 87 only requires driving the ring gear 82 to rotate one hundred and eighty degrees to quickly cut the flange, thereby improving the cutting and processing efficiency of the flange, thereby solving the problem that when the existing automatic loading and unloading laser cutting equipment for flange production is used to cut and process the alloy steel plate to prepare the flange, a robot arm is usually used to control the laser cutter to cut the alloy steel plate. Not only does the robot arm need to accurately control the laser cutter to cut the outer circular contour of the flange, but the excess material of the inner ring of the flange needs to be removed, resulting in cumbersome operation and affecting the cutting and preparation efficiency of the flange.

[0049] Example 2: Figure 1 、 Figures 7 to 9 As shown, a mounting frame 10 is installed on the upper end of the support plate 81, and a first motor 11 is installed on the upper end of the mounting frame 10. The output shaft end of the first motor 11 is fixedly connected to an electric push rod, and the piston rod end of the electric push rod is fixedly connected to a gear plate 83, which is meshed with a gear 84.

[0050] Specifically, when cutting flanges of different sizes, the toothed disc 83 is driven downward by starting the electric push rod, and the toothed disc 83 is made to slide between the two gears 84 for meshing, and then the first motor 11 is started to drive the electric push rod and the toothed disc 83 to rotate, and the toothed disc 83 is meshed with the transmission gear 84 to rotate, thereby driving the rotating rod 85 to rotate, and at the same time the rotating rod 85 drives the U-shaped fixing frame 86 and the laser cutter 87 to rotate and adjust the inner diameter, so as to adjust the cutting position according to the flanges of different sizes, and then the electric push rod is started to drive the toothed disc 83 to move upward and disengage from the gear 84, and at the same time drive the gear ring 82 to rotate, and the gear ring 82 is driven The movable gear 84 rotates, thereby driving the rotating rod 85 and the laser cutter 87 to rotate, so that the laser cutter 87 is used to cut the alloy steel plate 3 to process the flange, thereby solving the problem that the existing automatic loading and unloading laser cutting equipment for flange production is inconvenient to adjust the position of the laser cutter according to flanges of different models and sizes when cutting and preparing flanges, so that the laser cutter can quickly cut the flanges from the alloy steel plate, resulting in low flange cutting and preparation efficiency. When using a robotic arm to control the laser cutter to cut and prepare flanges of different models, a lot of time is wasted on adjustment and control, which is not only cumbersome to operate but also affects the preparation efficiency of the flanges.

[0051] like Figures 7 to 9 As shown, a T-shaped fixing block 13 is installed on one side of the support plate 81, and the two ends of the T-shaped fixing block 13 are rotatably connected to the rotating frames 14. A loading column 15 is installed between the rotating frames 14, and the outside of the loading column 15 is provided with a plurality of rubber teeth in a ring shape.

[0052] like Figures 7 to 9 As shown, a rotating groove 16 is opened inside the T-shaped fixed block 13, and 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 frame 14. The rotating shaft 19 is located outside the inner cavity of the rotating groove 16 and a fixed plate 18 is installed. A first torsion spring 17 is fixedly connected to one side of the fixed plate 18, and one end of the first torsion spring 17 is fixedly connected to the inner wall of the rotating groove 16.

[0053] Specifically, when the support plate 81 is driven to move downward, the T-shaped fixing block 13 is driven downward by the support plate 81, 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 loading column 15 to move downward, and a number of rubber teeth are provided on the outside of the loading column 15. As the loading column 15 moves downward, the loading column 15 abuts 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, and at the same time, the rotating frame 14 drives the loading column 15 to push the alloy steel plate 3 to move toward the tail of the workbench 1, thereby driving the complete alloy steel plate 3 to move to the bottom of the support plate 81 for The flange is cut and processed to prepare the flange, thereby realizing automatic loading of the alloy steel plate 3 and improving the efficiency of cutting and processing of the flange. When the support plate 81 moves upward and resets, the first torsion spring 17 will twist the fixed plate 18 to rotate and reset. At the same time, the fixed plate 18 drives the rotating shaft 19 to rotate, and then drives the rotating frame 14 to rotate and reset, and then wait for the next cutting and processing of the flange. This solves the problem that the existing automatic loading and unloading laser cutting equipment for flange production is inconvenient to automatically load and unload the alloy steel plate when laser cutting and preparing the flange, resulting in workers or robotic arms being required to clamp, recycle and load the alloy steel plate each time, resulting in low efficiency of laser cutting of the flange.

[0054] Working principle: when processing and manufacturing the flange, the alloy steel plate 3 is placed on the workbench, and the loading and cutting assembly 8 is driven to move downward, and the loading and cutting assembly 8 is started to cut the alloy steel plate 3 to form a through-hole in the middle of the flange. The waste generated by the cutting will fall into the slag discharge port 20 and pass through the hollow part of the bracket 92 for discharge and collection. Then, the alloy steel plate 3 is cut again by the loading and cutting assembly 8 to cut out the flange, thereby realizing the cutting processing of the flange. The cut flange will fall onto the bracket 92 in the slag discharge port 20, and 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 slide groove 91. At the same time, the sliding plate 94 squeezes the spring 96 to move downward, and The bracket 92 will drive the shift block 93 to move downward for two-thirds of the process, and the shift block 93 will abut against the abutment block 97. At the same time, the shift block 93 will flip over and drive the bracket 92 to rotate. At this time, the flange will slide from the bracket 92 into the inner cavity of the recovery port 21. Then, a recovery box is set under the recovery port 21 to catch the flange that falls out of the inner cavity of the recovery port 21 for collection. A brush is set on the outside of the bracket 92. When the bracket 92 moves downward and is rebounded by the spring 96, the bracket 92 will use the external brush to scrape and clean the laser cutting waste on the inner wall of the slag discharge port 20, so as to avoid the waste generated by the laser cutting from being not cleaned for a long time and cooling, hardening and sticking into a whole piece, which will affect the subsequent cutting process of the flange and the discharge and recovery of the waste.

[0055] When cutting flanges of different sizes, the toothed disc 83 is driven downward by starting the electric push rod, and the toothed disc 83 is made to slide between the two gears 84 for meshing, and then the first motor 11 is started to drive the electric push rod and the toothed disc 83 to rotate, and the toothed disc 83 is meshed with the transmission gear 84 to rotate, thereby driving the rotating rod 85 to rotate, and at the same time the rotating rod 85 drives the U-shaped fixing frame 86 and the laser cutter 87 to rotate and adjust the inner diameter, so as to adjust the cutting position according to the different sizes of flanges, and then the electric push rod is started to drive the toothed disc 83 to move upward and disengage from the gear 84, and at the same time drive the ring gear 82 to rotate, and the ring gear 82 drives the gear 84 to rotate, thereby driving the rotating rod 85 and the laser cutter 87 to rotate, so that the laser cutter 87 is used to cut the flange of the alloy steel plate 3;

[0056] When the support plate 81 is driven to move downward, the T-shaped fixing block 13 is driven downward by the support plate 81, 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 loading column 15 to move downward. A plurality of rubber teeth are provided on the outside of the loading column 15. As the loading column 15 moves downward, the loading column 15 abuts 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 loading column 15 to push the alloy steel plate 3 toward the workbench 1 The tail moves, thereby driving the complete alloy steel plate 3 to move to the bottom of the support plate 81 for cutting and processing to prepare the flange, thereby realizing automatic loading 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 the fixed plate 18 to rotate and reset, and at the same time, the fixed plate 18 drives the rotating shaft 19 to rotate, and then drives the rotating frame 14 to rotate and reset, and then wait for the next cutting and processing of the flange, thereby realizing the cyclic loading and unloading of the alloy steel plate 3 and improving the laser cutting and preparation efficiency of the flange.
