Description

Technical Field

[0001] The invention belongs to the technical field of laser cutting, in particular to a metal casting laser cutting device. Background Art

[0002] Metal castings are made by pouring liquid metal into a mold cavity with a shape and size that matches the part. After it cools and solidifies, a metal product in the form of a blank or part is obtained. It is an important basic component in industries such as machinery manufacturing and plays a key role in many fields. Cast pipe fittings are one type of metal casting. Before they are used, cast pipe fittings often need to be cut using a laser cutting device to meet size requirements.

[0003] A Chinese patent with announcement number CN116984765B discloses a cutting device for teaching purposes that prevents pipes from tipping over after cutting. By setting a rotating component, the cut pipe can be rotated from a horizontal state to a vertical state, and then the clamping can be released to allow it to fall naturally, without the need for manual lifting and transportation, thereby further improving work efficiency; by setting a one-way moving component, after the cut pipe is lowered, the first movable frame remains in the pushed position, and the second movable frame follows the strip plate to reset, so that the remaining pipe can be quickly clamped and fixed.

[0004] In the current existing technology, when laser cutting a pipe, a circular cutting method is usually adopted. Before cutting, the pipe is fixed by a special clamp. The special clamp has the function of rotating to make the pipe rotate at a uniform speed, thereby realizing the circular cutting of the pipe. However, this method requires reciprocating disassembly and assembly of the pipe during the cutting process. Each time a pipe is cut, it must be disassembled and assembled, resulting in the inability to carry out the cutting work continuously, affecting the cutting effect.

[0030] 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.

[0031] like Figures 1 to 7As shown, a metal casting laser cutting device described in an embodiment of the present invention includes a workbench 1, which is arranged at an angle, and a plurality of support plates 2 are fixedly installed on the front and back of the workbench 1, and a top limit plate 3 is fixedly installed between the support plates 2. A plurality of support legs 4 are fixedly installed on the bottom of the workbench 1, and a guide assembly is provided on the top of the workbench 1, and the guide assembly includes a guide plate 6, and the guide assembly guides the pipe to move along a preset direction through the guide plate 6. A cutting assembly is provided above the guide assembly, and the cutting assembly includes a laser cutting head 9. The cutting assembly performs laser cutting on the pipe through the laser cutting head 9, and a driving assembly for providing power to the guide assembly is provided at the bottom of the workbench 1. , a limiting assembly for limiting the position of the pipe is provided on the top of the top limiting plate 3, and a blanking assembly for automatic blanking is symmetrically provided on the inner side of the guide assembly; the pipe is conveyed to the top of the workbench 1 by the conveying assembly. Since the workbench 1 is inclined, the pipe will slide to the lower point along the surface of the workbench 1. The guide plate 6 is located in the middle position of the workbench 1. The guide plate 6 will block the sliding pipe and make it stay on the workbench 1. When cutting, the driving assembly will drive the guide plate 6 to slide along the workbench 1 to the lower point. When the guide plate 6 slides, the limiting assembly will limit the pipe so that the pipes other than the one that fits the guide assembly will not slide off. Therefore, when the guide plate 6 moves, it will make a pipe fitting that is in contact with it move along with it. When the pipe fitting moves along with the guide plate 6, since its rolling friction is less than the sliding friction, the pipe fitting will roll at a uniform speed. When the guide plate 6 moves, the cutting assembly will move along with the moving assembly, so that the laser cutting head 9 can perform laser cutting on the pipe fitting that is rolling at a uniform speed, thereby achieving the effect of circular cutting. When the cutting is completed, as the guide plate 6 continues to move, the unloading assembly will automatically unload the cut pipe fitting, thereby completing the cutting work of a pipe fitting. After that, the driving assembly will reset the guide plate 6. After the guide plate 6 is reset, the limit assembly will also be reset, thereby releasing the limit on the pipe fitting, and the pipe fitting will be After sliding down again, the pipe at the lowest position will fit with the guide plate 6 to prepare for the next cutting work. In summary, the present invention realizes highly automated, efficient and precise control of the laser cutting operation of pipe fittings through a unique and sophisticated structural design and a coordinated operation mechanism. By utilizing the tilt setting of the workbench 1 and the coordinated cooperation of the guide assembly, drive assembly, limit assembly and blanking assembly, the whole process of pipe fittings from transportation, cutting to blanking is realized. There is no need for frequent manual intervention, which greatly shortens the cutting cycle of a single pipe fitting and significantly improves production efficiency. It is especially suitable for cutting and processing of large quantities of metal casting pipe fittings, effectively reduces labor costs and production time costs, and realizes continuous cutting of pipe fittings.

[0032] like Figures 1 to 4As shown, the guide assembly also includes a moving seat 5 symmetrically slidably mounted on the top inclined surface of the workbench 1, a guide plate 6 is arranged between the two moving seats 5, and a driving block 7 is fixedly mounted on the bottom of the two moving seats 5, and the outer wall of the driving block 7 is slidably connected to the inner wall of the workbench 1, and the cutting assembly also includes a hinged seat 8, which is slidably mounted on the inner wall of the guide plate 6, and the laser cutting head 9 is rotatably mounted on the inner wall of the hinged seat 8; when the pipe fitting is transported to the workbench 1, the pipe fitting at the lowest position will fit with the guide plate 6, and after starting the driving assembly, the driving assembly will drive the moving seat 5 to move along the inclined surface of the workbench 1 through the driving block 7, and the moving seat 5 will drive the guide plate 6 to move when moving. Since when the guide plate 6 moves, the limit assembly will limit other pipe fittings except the fitted pipe fittings, The guide plate 6 will only drive one pipe to follow the movement, and because its rolling friction is smaller than the sliding friction, the pipe will roll at a uniform speed when moving. When the guide plate 6 moves, it will drive the laser cutting head 9 to move together through the hinge seat 8. The laser cutting head 9 cuts the pipe while the pipe rolls, thereby achieving the effect of automatic cutting of the pipe. During the cutting process, the pipe moves in a rolling manner, and the rolling friction is smaller than the sliding friction, ensuring that the pipe can move at a uniform and stable speed. At the same time, the cutting assembly moves synchronously with the guide assembly, so that the laser cutting head 9 can always maintain a relatively stable cutting position and speed with the pipe, thereby achieving precise circular cutting of the pipe, ensuring the flatness of the cutting section and the accuracy of the cutting size, effectively reducing cutting defects and scrap rate, and improving product quality.

[0033] like Figures 1 to 4 As shown, the driving assembly includes two groups of positioning seats 10 fixedly installed on the bottom of the workbench 1, and a traveling screw 11 is rotatably installed between the two groups of positioning seats 10. A driving motor 12 is fixedly installed on the bottom of the workbench 1, and the output end of the driving motor 12 is fixedly connected to one end of one of the traveling screws 11. The outer walls of the traveling screws 11 are fixedly installed with a transmission wheel 13, and a transmission belt 14 is installed between the two transmission wheels 13. The outer walls of the two traveling screws 11 are respectively threadedly connected with the inner walls of the two driving blocks 7; after starting the driving motor 12, the driving motor 12 will drive one of the traveling screws 11 to rotate, and through the cooperation of the transmission wheel 13 and the transmission belt 14, the other traveling screw 11 will follow and rotate synchronously. When the two traveling screws 11 rotate, they will cooperate with the threads of the two driving blocks 7 to make the driving block 7 move along the traveling screw 11, thereby providing power for the movement of the guide plate 6.

[0034] like Figures 4 to 6As shown, the limit assembly includes a column 15 symmetrically fixedly installed on the top of the top limit plate 3, and a slip ring 16 is slidably installed on the outer wall of the column 15. A limit plug 17 is fixedly installed between the two slip rings 16. The limit plug 17 is plugged into the inner wall of the top limit plate 3. A circular plate 18 is fixedly installed at one end of the column 15. An elastic member A19 is fixedly installed between the circular plate 18 and the slip ring 16 on the same side. An extrusion assembly is provided on the top of the guide plate 6; when the guide plate 6 moves downward, the guide plate 6 will drive the extrusion assembly to move together, and the extrusion assembly moves After that, the degree of squeezing on the limit plug 17 will be gradually reduced until the squeezing force disappears. During this process, the slip ring 16 will move in the direction away from the circular plate 18 under the action of the elastic member A19. When the slip ring 16 moves, it will drive the limit plug 17 to move. The limit plug 17 will pass through the top limit plate 3 and extend below it, thereby limiting the pipe fitting below the top limit plate 3, so that only the pipe fitting at the lowest position is able to move. When the guide plate 6 is reset, the extrusion assembly will follow and reset, thereby squeezing the limit plug 17 again to release the restriction on the pipe fitting.

[0035] like Figures 4 to 6 As shown, the extrusion assembly includes a right-angle plate 20, which is fixedly mounted on the top of the guide plate 6. An extrusion plate 21 is fixedly mounted on the end of the right-angle plate 20 away from the guide plate 6. An extrusion groove is provided on the outer wall of the limiting plug-in plate 17, and the extrusion plate 21 conflicts with the limiting plug-in plate 17 through the provided extrusion groove; when the guide plate 6 moves, the extrusion plate 21 is driven to move by the right-angle plate 20. When the guide plate 6 moves downward, the extrusion plate 21 slides out from the inner side of the extrusion groove, thereby causing the limiting plug-in plate 17 to limit the pipe fitting. On the contrary, when the guide plate 6 is reset, the extrusion plate 21 is also reset and inserted into the extrusion groove again. At this time, the limiting plug-in plate 17 no longer limits the pipe fitting.

[0036] like Figures 1 to 4 and Figure 7As shown, the blanking assembly includes a limiting column 22, which is fixedly mounted on the inner wall of the movable seat 5, and a lifting block 23 is slidably mounted on the inner wall of the movable seat 5. The inner wall of the lifting block 23 is slidably connected to the outer wall of the limiting column 22, and an elastic member B24 is fixedly mounted between the lifting block 23 and the movable seat 5. The guide plate 6 is fixedly mounted between the two lifting blocks 23, and a support plate 25 is symmetrically fixedly mounted on the top of the workbench 1; when the device completes the cutting work, as the guide plate 6 continues to move, the guide plate 6 will conflict with the support plate 25, and the support plate 24 will be fixedly mounted on the top of the workbench 1. 5 will squeeze the guide plate 6 to make it move up in the vertical direction of the workbench 1. After the guide plate 6 moves up, it will separate from the pipe fitting, and the pipe fitting will no longer contact the guide plate 6. Therefore, the pipe fitting will pass from under the guide plate 6 and slide along the workbench 1, thereby achieving the effect of automatic unloading of the pipe fitting. When the guide plate 6 moves up, the lifting block 23 will slide along the limiting column 22. At this time, the elastic member B24 is in a contracted state. When the guide plate 6 moves in the opposite direction, the elastic member B24 will reset the lifting block 23 through its own elastic force, thereby resetting the guide plate 6.

[0037] like Figures 2 to 3 and Figure 8 As shown, the top of the workbench 1 is symmetrically fixed with a rotating shaft 26, and the outer wall of the rotating shaft 26 is rotatably mounted with a correction plate 27. The front and back of the workbench 1 are fixedly mounted with a positioning plate 28. An arc-shaped elastic telescopic rod 29 is fixedly mounted between the positioning plate 28 and the correction plate 27 on the same side. A rotating component is provided on one side of the movable seat 5. When the guide plate 6 moves downward, the movable seat 5 will drive the rotating component to separate from the correction plate 27, and the two correction plates 27 will rotate to both sides around the rotating shaft 26 under the action of the arc-shaped elastic telescopic rod 29, so that the two correction plates 27 Open, at this time, the pipe can be transported to the workbench 1 through the conveying assembly to prevent material jamming. When the guide plate 6 is reset, the rotating assembly will reset along with the guide plate 6, thereby squeezing the two correction plates 27. After being squeezed, the two correction plates 27 will rotate to a parallel state, thereby centering the pipe fittings on the workbench 1 to ensure the accuracy of subsequent cutting. After each cutting work is completed, as the guide plate 6 is reset, the correction plate 27 will calibrate the pipe once, without the need for manual operation to calibrate, avoiding the situation of forgetting to calibrate.

[0038] like Figure 8As shown, the rotating assembly includes a receiving plate 30, which is fixedly mounted on the outer wall of the movable seat 5, and a rotating frame 31 is fixedly mounted on the end of the receiving plate 30 away from the movable seat 5, and a squeezing roller 32 is rotatably mounted on the inner wall of the rotating frame 31, and the squeezing roller 32 is in conflict with the correction plate 27; when the guide plate 6 moves downward, the movable seat 5 will drive the squeezing roller 32 to move through the receiving plate 30 and the rotating frame 31, thereby separating the squeezing roller 32 from the correction plate 27, and at this time the two correction plates 27 will open to both sides, and when the guide plate 6 is reset, the squeezing roller 32 will squeeze the correction plate 27, so that the two correction plates 27 rotate to be parallel, thereby realizing the calibration of the pipe.

[0039] like Figures 2 to 4 As shown, a plurality of scrapers 33 are fixedly installed at the bottom of the guide plate 6, and the scrapers 33 are arranged at an angle. The scrapers 33 are in contact with the workbench 1, and a plurality of blanking troughs 34 are provided on the top of the workbench 1, and the blanking troughs 34 are arranged crosswise with the scrapers 33; when the guide plate 6 moves, the guide plate 6 will drive the scraper 33 to move, and the scraper 33 will clean the surface of the workbench 1 when it moves, thereby preventing impurities adhering to the surface of the workbench 1 from affecting the cutting accuracy. The scraper 33 is arranged at an angle, so when the scraper 33 moves back and forth, the scraped impurities will move to both sides of the scraper 33, and because a plurality of blanking troughs 34 arranged crosswise with the scraper 33 are provided on the workbench 1, the impurities moving to both sides of the scraper 33 will fall through the blanking troughs 34, thereby preventing the scraped impurities from remaining on the workbench 1.

[0040] like Figures 1 to 2 and Figure 5 As shown, an extension plate 35 is fixedly installed on one side of the top limit plate 3, and a number of exhaust boxes 36 are fixedly installed on the inner wall of the extension plate 35, and a number of diversion pipes 37 are fixedly installed between the exhaust boxes 36, and an air guide pipe 38 is fixedly installed between the diversion pipes 37. An air pump 39 is fixedly installed on the outer wall of the air guide pipe 38; when the pipeline rolls down from the workbench 1, it will pass under the exhaust box 36, and the air pump 39 will draw in external air to generate airflow and transport it to the diversion pipe 37 through the air guide pipe 38. After the airflow enters the diversion pipe 37, it will be blown toward the pipe fitting through the exhaust box 36, thereby cleaning the surface of the pipe fitting to prevent dust, metal chips and other impurities from adhering to the surface of the pipe fitting during transportation, thereby affecting the cutting quality.

[0041] Working principle: The pipe is transported to the top of the workbench 1 through the conveying component. Since the workbench 1 is set at an angle, the pipe will slide along the surface of the workbench 1 to the lower point. The guide component is located in the middle of the workbench 1. The guide component will block the sliding pipe and make it stay on the workbench 1. When cutting, the driving component will drive the guide component to slide along the workbench 1 to the lower point. When the guide component slides, the limit component will limit the pipe so that other pipes except the one that fits the guide component will not slide. Therefore, when the guide component moves, it will cause the pipe that fits with it to follow the movement. When the pipe follows the guide component to move, since its rolling friction is less than the sliding friction, the pipe will roll at a uniform speed. While the guide component moves, the cutting component will move with the moving component, thereby performing laser cutting on the pipe that rolls at a uniform speed to achieve the effect of circular cutting. When the cutting is completed, the guide component moves with the moving component. As the assembly continues to move, the blanking assembly will automatically unload the cut pipe, thereby completing the cutting of a pipe. After that, the driving assembly will reset the guide assembly. After the guide assembly is reset, the limit assembly will also be reset, thereby releasing the limit on the pipe, and the pipe will slide again. The pipe at the lowest position will fit with the guide assembly to prepare for the next cutting. In summary, the present invention realizes highly automated, efficient and precise control of pipe laser cutting operations through a unique and sophisticated structural design and collaborative operation mechanism. The tilt setting of the workbench 1 and the coordinated cooperation of the guide assembly, driving assembly, limit assembly and blanking assembly are utilized to realize the full automation of the pipe from transportation, cutting to unloading, without the need for frequent manual intervention, greatly shortening the cutting cycle of a single pipe, and significantly improving production efficiency. It is especially suitable for cutting and processing large quantities of metal casting pipes, effectively reducing labor costs and production time costs, and realizing continuous cutting of pipes.

[0042] When the pipe is transported to the workbench 1, the pipe at the lowest position will fit with the guide plate 6. After the driving assembly is started, the driving assembly will drive the moving seat 5 to move along the inclined surface of the workbench 1 through the driving block 7. The moving seat 5 will drive the guide plate 6 to move when it moves. Since the limit assembly will limit the other pipes except the fitted pipes when the guide plate 6 moves, the guide plate 6 will only drive one pipe to follow the movement. Since its rolling friction is less than the sliding friction, the pipe will roll at a uniform speed when it moves. When the guide plate 6 moves, it will drive the laser cutting machine through the hinged seat 8. The cutting head 9 moves together, and the laser cutting head 9 cuts the pipe while the pipe rolls, thereby achieving the effect of automatic cutting of the pipe. During the cutting process, the pipe moves in a rolling manner, and the rolling friction is less than the sliding friction, ensuring that the pipe can move at a uniform and stable speed. At the same time, the cutting component moves synchronously with the guide component, so that the laser cutting head 9 can always maintain a relatively stable cutting position and speed with the pipe, thereby achieving precise circular cutting of the pipe, ensuring the flatness of the cutting section and the accuracy of the cutting size, effectively reducing cutting defects and scrap rate, and improving product quality.

[0043] After starting the drive motor 12, the drive motor 12 will drive one of the travel screws 11 to rotate, and through the cooperation of the transmission wheel 13 and the transmission belt 14, the other travel screw 11 will follow and rotate synchronously. When the two travel screws 11 rotate, they will cooperate with the threads of the two drive blocks 7 to make the drive blocks 7 move along the travel screw 11, thereby providing power for the movement of the guide plate 6. When the guide plate 6 moves downward, the guide plate 6 will drive the extrusion assembly to move together. After the extrusion assembly moves, the degree of extrusion on the limit plug 17 will gradually decrease until the extrusion force disappears. In this process, the slip ring 16 will move in the direction away from the circular plate 18 under the action of the elastic member A19. When the slip ring 16 moves, it will bring When the movable limit plate 17 moves, the limit plate 17 will pass through the top limit plate 3 and extend to the bottom thereof, thereby limiting the pipe fitting below the top limit plate 3, so that only the pipe fitting at the lowest position is able to move. When the guide plate 6 is reset, the extrusion assembly will follow the reset, thereby squeezing the limit plate 17 again to release the restriction on the pipe fitting. When the guide plate 6 moves, it will drive the extrusion plate 21 to move through the right-angle plate 20. When the guide plate 6 moves downward, the extrusion plate 21 will slide out from the inner side of the extrusion groove, thereby limiting the pipe fitting by the limit plate 17. On the contrary, when the guide plate 6 is reset, the extrusion plate 21 will also be reset and inserted into the extrusion groove again. At this time, the limit plate 17 no longer limits the pipe fitting.

[0044] When the device completes the cutting work, as the guide plate 6 continues to move, the guide plate 6 will conflict with the abutment plate 25, and the abutment plate 25 will squeeze the guide plate 6 to make it move up along the vertical direction of the workbench 1. After the guide plate 6 moves up, it will separate from the pipe fitting, and the pipe fitting will no longer contact the guide plate 6. Therefore, the pipe fitting will pass from under the guide plate 6 and slide along the workbench 1, thereby achieving the effect of automatic unloading of the pipe fitting. When the guide plate 6 moves up, the lifting block 23 will slide along the limit column 22. At this time, the elastic part B24 is in a contracted state. When the guide plate 6 moves in the opposite direction, the elastic part B24 will reset the lifting block 23 through the action of its own elastic force, thereby resetting the guide plate 6.

[0045] When the guide plate 6 moves downward, the moving seat 5 will drive the rotating assembly to separate from the correction plate 27. The two correction plates 27 will rotate to both sides around the rotating shaft 26 under the action of the arc-shaped elastic telescopic rod 29, so that the two correction plates 27 are opened. At this time, the pipe can be conveyed to the workbench 1 through the conveying assembly to prevent the material from being stuck. When the guide plate 6 is reset, the rotating assembly will follow the guide plate 6 to reset together, thereby squeezing the two correction plates 27. After being squeezed, the two correction plates 27 will rotate to a parallel state, thereby calibrating the pipe fittings on the workbench 1 to ensure that the pipe fittings on the workbench 1 are centered. To ensure the accuracy of continuous cutting, each time a cutting work is completed, as the guide plate 6 is reset, the correction plate 27 will perform a correction work on the pipe. No manual operation is required for correction, so as to avoid forgetting to calibrate. When the guide plate 6 moves to a lower position, the movable seat 5 will drive the squeezing roller 32 to move through the receiving plate 30 and the rotating frame 31, so that the squeezing roller 32 is separated from the correction plate 27. At this time, the two correction plates 27 will open to both sides. After the guide plate 6 is reset, the squeezing roller 32 will squeeze the correction plate 27, so that the two correction plates 27 are rotated to be parallel, thereby realizing the calibration of the pipe.

[0046] When the guide plate 6 moves, the guide plate 6 will drive the scraper 33 to move. When the scraper 33 moves, it will clean the surface of the workbench 1, thereby preventing impurities adhering to the surface of the workbench 1 from affecting the cutting accuracy. The scraper 33 is arranged at an angle, so when the scraper 33 moves back and forth, the scraped impurities will move to the sides of the scraper 33. Because the workbench 1 is provided with a plurality of blanking troughs 34 arranged crosswise with the scraper 33, the impurities moving to the sides of the scraper 33 will fall through the blanking troughs 34, thereby preventing the scraped impurities from remaining on the workbench 1. When the pipeline rolls down from the workbench 1, it will pass under the exhaust box 36, and the air pump 39 will draw in external air to generate airflow and transport it to the diversion pipe 37 through the air guide pipe 38. After the airflow enters the diversion pipe 37, it will be blown to the pipe fitting through the exhaust box 36, thereby cleaning the surface of the pipe fitting, preventing impurities such as dust and metal chips from adhering to the surface of the pipe fitting during transportation, thereby affecting the cutting quality.
