Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and more particularly to a metal processing laser shearing device. Background Art

[0002] Metal processing laser shearing device is a modern cutting device that uses a high-power density laser beam to irradiate the workpiece, causing the material to melt, vaporize, ablate or reach the ignition point quickly, and uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby cutting the workpiece. Laser cutting technology has been widely used in the field of metal processing due to its advantages of high precision, high efficiency and low cost.

[0003] Laser cutting technology is widely used in the circular cutting of metal tubes. When in use, the staff pushes the metal tube along the placement port through the internal conveying device to the bottom of the laser cutting nozzle according to the required cutting length, and the front end of the metal tube is resisted by the circular seat to maintain stability. The laser beam generated by the laser cutting nozzle is focused by the lens to form a high-power density laser point, thereby forming a laser beam from top to bottom. The laser beam heats the metal material to a molten state, and then blows non-oxidizing gases such as argon, nitrogen, etc. through the nozzle, relying on the gas pressure to discharge the liquid metal to form an incision.

[0004] However, in the actual processing process, since the laser beam of the laser cutting nozzle is cut in conjunction with an auxiliary gas, the molten metal liquid is blown to the outside by the auxiliary gas during cutting, but the molten metal liquid is also blown to the inside of the metal tube by the auxiliary gas to form slag and inner diameter burrs, affecting the production quality of the metal tube. It is usually necessary to reprocess the cut metal tube to remove the slag and inner diameter burrs in the tube, which reduces the production efficiency of the metal tube and increases the production cost and production steps of the metal tube.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a metal processing laser shearing device. Summary of the invention

[0006] In view of the shortcomings of the prior art, the object of the present invention is to provide a metal processing laser shearing device.

A driving motor is arranged inside the workbench, and the output end of the driving motor extends into the supporting seat and is fixedly connected to the insert rod. Fixing blocks are arranged in an array around the insert rod, and cleaning blocks in a wavy shape are arranged on the surfaces of the fixing blocks;

[0009] A pushing component for pushing the metal pipe off the cleaning component and into the workbench after the cleaning component finishes cleaning, including N moving rods sliding and distributed in an array inside the supporting seat. One end of the moving rod extends outside the supporting seat and is fixedly installed with a pressing ring. The moving rod drives the pressing ring to contact the pipe wall of the metal pipe through the moving action, so that the pipe wall of the metal pipe completes the separation action from the cleaning component.

[0010] Preferably, the cleaning component further includes an arc-shaped block with a curved end face. The arc-shaped block is arranged on one side of the fixing block. Both the fixing block and the arc-shaped block are connected to the insert rod through telescopic shafts, and the telescopic shafts are connecting rods with telescopic elasticity.

[0011] Preferably, the telescopic shaft is divided into an upper end and a lower end. The upper end of the telescopic shaft is a sliding rod, and the bottoms of the fixing block and the arc-shaped block are fixedly connected to the top of the sliding rod. The lower end of the telescopic shaft is a telescopic sleeve, and a telescopic groove is opened inside the telescopic sleeve. The sliding rod can slide inside the telescopic groove, and a telescopic spring is further arranged inside the telescopic groove. The top end of the telescopic spring is fixedly connected to the bottom end of the sliding rod, and the bottom end of the telescopic spring is fixedly connected to the inner wall of the telescopic groove.

[0012] Preferably, balls are arranged on the arc surface of the arc-shaped block, and the balls are used to replace sliding friction with rolling friction.

[0013] Preferably, a pulling back horizontal bar is arranged at the connection between the fixing block and the arc-shaped block, and the height of the pulling back horizontal bar is the same as the height of the arc-shaped block.

[0014] Preferably, a conveying device for pushing the metal tube to move inside the placement opening is provided inside the placement opening, and the position of the abutment seat corresponds to that of the clamping device.

[0015] Preferably, an extrusion spring is provided on the outer side of the moving rod. One end of the extrusion spring is fixedly connected to the extrusion ring, and the other end is fixedly connected to the end face of the abutment seat.

[0016] Preferably, a controller is further provided on the workbench, and the controller can control the operation of the electronic components of the device.

[0017] Preferably, an internal component is provided inside the cleaning block. A sliding groove is formed inside the internal component. A sliding block is slidably arranged inside the sliding groove. A cleaning spring is further provided inside the sliding groove. One end of the cleaning spring is fixedly connected to the inner wall of the sliding groove, and the other end of the cleaning spring is fixedly connected to the bottom of the sliding block.

[0018] Preferably, a plain bearing is provided at one end of the extrusion ring facing the metal tube. A grinding ring is provided on the plain bearing. The extrusion ring is rotationally connected to the grinding ring through the plain bearing. A linkage rod is fixedly connected to the grinding ring. A connection groove is formed on the surface of the insertion rod, and the linkage rod is movably connected inside the connection groove.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, when the pipe orifice of the metal tube contacts the arc surface of the arc-shaped block and the metal tube continues to move, the arc-shaped block will squeeze the sliding rod downward. The sliding rod will move inside the telescopic groove and squeeze the telescopic spring. The fixed block fixedly connected to the arc-shaped block will also move downward to squeeze the sliding rod until the cleaning assembly completely enters the inner wall of the metal tube. At this time, the laser cutting nozzle adjusts its position to cut the metal tube. At the same time, the driving motor is started to drive the insertion rod to rotate. The insertion rod drives the fixed block to rotate. The rotating fixed block can drive the wavy cleaning block to scrape the inner wall of the metal tube, eliminating the need for reprocessing the inner wall of the metal tube to remove slag after cutting, improving the production efficiency of the metal tube, and reducing the production cost and production steps of the reprocessing of the metal tube.

[0021] 2. In the present invention, when the extrusion ring is squeezed, it will contract towards the abutment seat. At this time, the pipe orifice of the metal tube will contact the arc surface of the arc-shaped block and compress the arc-shaped block. After the metal tube is cut, the cut and separated metal tube is located outside the cleaning assembly. At this time, the conveying device retracts the uncut metal tube into the placement opening. The contact pressure at one end of the cut and separated metal tube disappears. The extrusion spring rebounds the extrusion ring outwards, so as to push the metal tube against the extrusion ring outwards. The telescopic elastic force of the extrusion spring is used to automatically eject the cut metal tube after processing, eliminating the need for manual removal, saving time and effort, and at the same time avoiding potential safety hazards when the staff holds and removes it.

[0022] 3. In the present invention, when the cleaning block is extruded by the square metal tube, the outside of the cleaning block will be compressed and deformed. When the sliding block is extruded, it will compress the cleaning spring and contract in the sliding groove until it is compressed into the square metal tube, so as to adapt to the inner diameter of the square metal tube. When the square metal tube reaches the preset position, the insertion rod rotates. When rotating, the cleaning block will adjust its height according to the change of the inner diameter of the square metal tube under the elastic action of the cleaning spring, so as to realize the cleaning of slag impurities inside the square metal tube, increase the types of processed metal tubes, and improve the practicability of the device.

[0023] 4. In the present invention, when the insertion rod starts to rotate under the action of the driving motor, the linkage rod fixedly connected to the insertion rod will drive the grinding ring attached to the surface of the circular metal tube to rotate. And due to the action of the plain bearing, the rotation of the grinding ring will not affect the extrusion ring to compress the extrusion spring to realize the ejection function. When the cleaning block rotates with the insertion rod to clean the slag burrs inside the circular metal tube, the rotating grinding ring also grinds the burrs on the outer diameter of the circular metal tube. The structural design is ingenious, and the internal slag and outer diameter burrs of the metal tube are cleaned simultaneously, improving the processing quality and effect of the metal tube.

[0042] Embodiment 1

[0043] As Figures 1 - 12As shown in the figure, the present invention provides a metal processing laser shearing device, which includes a workbench 1, a loading box 2 arranged on one side of the workbench 1, a telescopic device 4 arranged inside the workbench 1 for controlling the up and down movement of the laser head, and a laser cutting head 6 arranged below the telescopic device 4. It should be noted that the movement trajectory of the molten metal liquid generated during laser cutting by the laser cutting head 6 is diffusive inside the metal tube 13. Due to the obstruction of the unmolten metal and the auxiliary air flow in the metal tube 13, the slag will be ejected obliquely downward from the cutting point, rather than directly downward. A moving device 12 for adjusting the cutting position of the laser cutting head 6 is arranged below the telescopic device 4. The moving device 12 is a control component for the lateral movement of the laser cutting head 6 in the prior art. A placement opening 3 is arranged on one side of the loading box 2. The placement opening 3 extends into the workbench 1 and is provided with a clamping device 7 for clamping the metal tube 13. The clamping device 7 is a component for clamping pipes in the prior art. A base 8 is arranged inside the workbench 1, and the position of the base 8 corresponds to that of the clamping device 7;

[0044] A conveying device for pushing the metal tube 13 to move inside the placement opening 3 is arranged inside the placement opening 3. The conveying device is a component for conveying the metal tube 13 in the prior art. The metal tube 13 is inserted into the placement opening 3, and through the parameters preset by the conveying device, the metal tube 13 is conveyed into the workbench 1. The clamping device 7 can fix and rotate the metal tube 13. A controller 5 is also arranged on the workbench 1. The controller 5 can control the operation of the electronic components of the device. Before processing, the operator inputs the execution movement parameters of the laser cutting nozzle into the controller 5 to control the telescopic device 4 and the moving device 12 to drive the laser cutting nozzle for processing displacement. An outlet 11 is arranged on one side of the workbench 1. After processing, the metal tube 13 falling inside the workbench 1 can be transported to the outside through the outlet 11.

[0045] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 11As shown in the figure, it further includes a cleaning assembly 9 for cleaning the inner diameter burrs and slag in the metal pipe 13. The cleaning assembly 9 includes an insertion rod 901 that is rotatably arranged on the abutment 8. A driving motor 908 is arranged inside the workbench 1. The output end of the driving motor 908 extends into the abutment 8 and is fixedly connected to the insertion rod 901. Fixing blocks 905 are movably arranged in an array around the insertion rod 901. A cleaning block 906 in a wavy shape is arranged on the surface of the fixing block 905. The cleaning block 906 is a rigid strip brush. Compared with a straight strip, the wavy strip brush can make the cleaning area of the cleaning block 906 larger and more thorough when rotating inside the metal pipe 13. At the same time, since the cleaning block 906 fits the inner wall of the metal pipe 13, the slag removed by cleaning will also be carried out of the inner wall of the metal pipe 13 by the wavy curved cleaning block 906;

[0046] The cleaning assembly 9 further includes an arc-shaped block 903 with an arc-shaped end face. The arc-shaped block 903 is arranged on one side of the fixing block 905. A ball 904 is arranged on the arc surface of the arc-shaped block 903. The ball 904 is used to replace sliding friction with rolling friction, making it easier for the metal pipe 13 to move when the pipe orifice fits the arc surface of the arc-shaped block 903, so that the arc-shaped block 903 can more easily compress the telescopic shaft 902. Both the fixing block 905 and the arc-shaped block 903 are connected to the insertion rod 901 through the telescopic shaft 902. The telescopic shaft 902 is a connecting rod with telescopic elasticity. The telescopic shaft 902 is divided into an upper end and a lower end. The upper end of the telescopic shaft 902 is a sliding rod 9022. The bottoms of the fixing block 905 and the arc-shaped block 903 are fixedly connected to the top of the sliding rod 9022. The lower end of the telescopic shaft 902 is a telescopic sleeve 9021. A telescopic groove 9023 is opened inside the telescopic sleeve 9021. The sliding rod 9022 can slide inside the telescopic groove 9023. A telescopic spring 9024 is further arranged inside the telescopic groove 9023. The top end of the telescopic spring 9024 is fixedly connected to the bottom end of the sliding rod 9022. The bottom end of the telescopic spring 9024 is fixedly connected to the inner wall of the telescopic groove 9023.

[0047] When the metal tube 13 is pushed by the conveying device towards the abutment 8, the mouth of the metal tube 13 will contact the arc surface of the arc-shaped block 903. As the metal tube 13 continues to move, the arc-shaped block 903 will squeeze the sliding rod 9022 downward. The sliding rod 9022 will move inside the telescopic groove 9023 and squeeze the telescopic spring 9024. The fixed block 905 fixedly connected to the arc-shaped block 903 will also move downward to squeeze the sliding rod 9022 until the cleaning assembly 9 completely enters the inner wall of the metal tube 13. At this time, the laser cutting nozzle adjusts its position to cut the metal tube 13. During cutting, the auxiliary gas will spray the molten metal liquid along an obliquely downward trajectory onto the inner wall of the metal tube 13. The cleaning assembly 9 will not obstruct the normal circular cutting of the metal tube 13 by the laser cutting nozzle. At the same time, the driving motor 908 is started to drive the insertion rod 901 to rotate. The insertion rod 901 drives the fixed block 905 to rotate. The rotating fixed block 905 can drive the wavy cleaning block 906 to scrape the inner wall of the metal tube 13, eliminating the need for reprocessing the inner wall of the metal tube 13 to remove slag after cutting, improving the production efficiency of the metal tube 13 and reducing the production cost and production steps of reprocessing the metal tube 13.

[0048] Working principle: Controlled by the parameters preset by the conveying device in advance, the metal tube 13 is conveyed into the workbench 1. The clamping device 7 can fix and rotate the metal tube 13. Before processing, the operator inputs the execution movement parameters of the laser cutting nozzle into the controller 5 to control the telescopic device 4 and the moving device 12 to drive the laser cutting nozzle for processing displacement. When the metal tube 13 is pushed by the conveying device towards the abutment 8, the mouth of the metal tube 13 will contact the arc surface of the arc-shaped block 903. As the metal tube 13 continues to move, the arc-shaped block 903 will squeeze the sliding rod 9022 downward. The sliding rod 9022 will move inside the telescopic groove 9023 and squeeze the telescopic spring 9024. The fixed block 905 fixedly connected to the arc-shaped block 903 will also move downward to squeeze the sliding rod 9022 until the cleaning assembly 9 completely enters the inner wall of the metal tube 13. At this time, the laser cutting nozzle adjusts its position to cut the metal tube 13. At the same time, the driving motor 908 is started to drive the insertion rod 901 to rotate. The insertion rod 901 drives the fixed block 905 to rotate. The rotating fixed block 905 can drive the wavy cleaning block 906 to scrape the inner wall of the metal tube 13. After processing, the metal tube 13 that falls inside the workbench 1 can be transported to the outside through the discharge port 11.

[0049] Embodiment 2

[0050] For the circular metal tube, after the cutting of the metal tube 13 is completed, the metal tube 13 is still clamped by the cleaning assembly 9 from the inside to the outside and needs to be taken out manually, which is time-consuming and laborious.

[0051] Such as Figure 2 、 Figure 3 、 Figure 4 、Figure 5 , Figure 6 and Figure 11 As shown in Figure 5 , Figure 6 and Figure 11 , the present invention provides a metal processing laser shearing device, including a pushing component 10, which is used to push the metal tube 13 from the cleaning component 9 onto the bottom of the workbench 1 after the cleaning component 9 finishes cleaning. It includes N moving rods 1001 slidably and arrayedly distributed inside the abutment 8. One end of the moving rod 1001 extends to the outside of the abutment 8 and is fixedly installed with a pressing ring 1002. The moving rod 1001 drives the pressing ring 1002 to abut against the wall of the metal tube 13 through a moving action, so that the wall of the metal tube 13 completes the separation action from the cleaning component 9. An extrusion spring 1003 is arranged outside the moving rod 1001. One end of the extrusion spring 1003 is fixedly connected to the pressing ring 1002, and the other end is fixedly connected to the end face of the abutment 8. A pulling cross bar 907 is arranged at the connection between the fixed block 905 and the arc-shaped block 903. The height of the pulling cross bar 907 is the same as the height of the arc-shaped block 903. The pulling cross bar 907 can bring out the slag debris scraped from the inside of the metal tube 13 when the cut and separated metal tube 13 is pushed out.

[0052] Working principle: When the metal tube 13 moves towards the abutment 8, it will first abut against the pressing ring 1002. The pressing ring 1002 will contract towards the abutment 8 under the extrusion. At this time, the pipe orifice of the metal tube 13 will contact the arc surface of the arc-shaped block 903 and compress the arc-shaped block 903. After the metal tube 13 is cut, the cut and separated metal tube 13 is located outside the cleaning component 9. At this time, the conveying device retracts the uncut metal tube 13 into the placing port 3. The abutting pressure at one end of the cut and separated metal tube 13 disappears, and the extrusion spring 1003 rebounds the pressing ring 1002 outwards, so that the metal tube 13 abutting against the pressing ring 1002 is pushed outwards until it falls into the workbench 1 for the staff to collect.

[0053] Embodiment III

[0054] Regarding the square metal tube 13, it should be noted that since the inner radius of the square metal tube 13 is not uniform, the cleaning block 906 in Embodiment I cannot clean the entire inner wall of the square metal tube 13 during rotation.

[0055] As Figure 13 and Figure 14As shown in the figure, the present invention provides a metal processing laser shearing device, including: The extrusion ring 1002 is a square ring, and the outside of the cleaning block 906 is a flexible block with a friction surface on its surface. When the cleaning block 906 is extruded by the square metal tube 13, the outside of the cleaning block 906 will be compressed and deformed. An internal part 909 is provided inside the cleaning block 906. A sliding groove 911 is opened inside the internal part 909. A sliding block 910 is slidably arranged inside the sliding groove 911. A cleaning spring 912 is also provided inside the sliding groove 911. One end of the cleaning spring 912 is fixedly connected to the inner wall of the sliding groove 911, and the other end of the cleaning spring 912 is fixedly connected to the bottom of the sliding block 910. When the sliding block 910 is extruded, it will compress the cleaning spring 912 and contract inside the sliding groove 911, so as to adapt to the inner diameter of the square metal tube 13.

[0056] When the cleaning block 906 is extruded by the square metal tube 13, the outside of the cleaning block 906 will be compressed and deformed. When the sliding block 910 is extruded, it will compress the cleaning spring 912 and contract inside the sliding groove 911 until it is compressed into the square metal tube 13, so as to adapt to the inner diameter of the square metal tube 13. When the square metal tube 13 reaches the preset position, the insertion rod 901 rotates. When rotating, the cleaning block 906 will adjust its height according to the change of the inner diameter of the square metal tube 13 under the elastic action of the cleaning spring 912, so as to clean the slag impurities inside the square metal tube 13, increasing the types of processed metal tubes 13 and improving the practicability of the device.

[0057] Embodiment Four

[0058] For the circular metal tube 13, it should be noted that during the cutting process, when the cutting end of the circular metal tube 13 makes a circumferential cut, not only will slag be ejected into the tube by the auxiliary gas, but due to the unevenness of the auxiliary gas, burrs will also appear on the outside of the cutting end.

[0059] As Figure 15 and Figure 16 As shown in the figure, the present invention provides a metal processing laser shearing device, including: One end of the extrusion ring 1002 facing the metal tube 13 is provided with a plain bearing 1004. The plain bearing 1004 is a connecting piece for rotatably connecting two components in the prior art. A grinding ring 1005 is provided on the plain bearing 1004. The grinding ring 1005 is a grinding block with a grinding function on its surface. The extrusion ring 1002 is rotatably connected to the grinding ring 1005 through the plain bearing 1004. A linkage rod 1006 is fixedly connected to the grinding ring 1005. A connection groove 1007 is opened on the surface of the insertion rod 901. The linkage rod 1006 is movably connected inside the connection groove 1007.

[0060] When the insertion rod 901 starts to rotate under the action of the driving motor 908, the linkage rod 1006 fixedly connected to the insertion rod 901 will drive the grinding ring 1005 that fits the surface of the circular metal pipe 13 to rotate. And due to the action of the plain bearing 1004, the rotation of the grinding ring 1005 will not affect the compression of the compression spring 1003 by the extrusion ring 1002. This realizes the function that while the cleaning block 906 rotates with the insertion rod 901 to clean the slag burrs inside the circular metal pipe 13, the rotating grinding ring 1005 also grinds the outer diameter burrs of the circular metal pipe 13, achieving simultaneous cleaning of the internal slag and outer diameter burrs of the metal pipe 13 and improving the processing quality and effect of the metal pipe 13.

[0061] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to the instructions shown in the accompanying drawings and the above description; however, any equivalent changes made by those familiar with the technology in the technical field of the present invention within the scope of the technical solution of the present invention, using the technical content disclosed above for some modifications, decorations and evolutions, are all equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
