Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, specifically relating to a metal laser cutting machine for building engineering based on intelligent manufacturing. Background Technology

[0002] Laser cutting technology utilizes a focused, high-power-density laser beam to irradiate the surface of a workpiece, causing the irradiated material to rapidly melt, vaporize, or reach its ignition point. Simultaneously, a high-speed gas flow coaxial with the laser beam removes the molten material, thus achieving workpiece separation. Compared to traditional flame cutting and plasma cutting, laser cutting offers significant advantages such as narrower kerf, smaller heat-affected zone, higher cut surface quality, higher processing precision, and greater automation. In recent years, with the maturation and cost reduction of high-power fiber laser technology, laser cutting equipment has been increasingly widely used in the metal processing field.

[0003] The announcement number CN120038454A discloses a laser cutting machine for processing aluminum profiles, which includes a grinding unit for grinding the cutting edge of the aluminum profile cut by the laser cutter, a drive unit for driving the grinding unit to rotate periodically, and an adjustment unit for adjusting the position of the grinding unit in coordination with the movement of the laser cutter.

[0004] In the aforementioned application documents, a tapered surface is provided on the outer wall of the shearing needle, which, in conjunction with a second spring, releases a downward elastic force on the shearing needle, squeezing the shearing needle into the cutting seam of the aluminum profile. This achieves the effect of simultaneously performing laser cutting and grinding. However, in existing devices, when the shearing needle only performs rotational or lifting movements, the removal effect on unevenly distributed burrs in the cutting seam is poor.

The system comprises: rod 1; rotating rod 2, rotatably mounted on the top of a fixed plate; rotating rod 3, rotatably mounted on the bottom of a mounting plate; a telescopic assembly located at the bottom of the mounting plate; and a mounting frame fixedly mounted on the bottom of the mounting plate. A pulley 1 is mounted on the left side of rotating rod 1, and a pulley 2 is mounted on the right side of rotating rod 2. Pulley 1 and pulley 2 are connected by a transmission belt. A bevel gear 1 is mounted on the left side of rotating rod 2, and a bevel gear 2 is mounted on the top of rotating rod 3. A transmission friction block is mounted on the bottom of rotating rod 3. A turntable is rotatably mounted on the bottom of the telescopic assembly, and a reciprocating lead screw is fixedly mounted on the bottom of the turntable. A shearing needle is fixedly mounted on the bottom of the reciprocating lead screw.

[0007] According to the above technical solution, the reciprocating lead screw and the mounting frame are connected through and rotatably. The bottom of the mounting frame is provided with an internal thread, and the external thread and the internal thread of the reciprocating lead screw mesh with each other.

[0008] According to the above technical solution, the first bevel gear and the second bevel gear mesh with each other, and the transmission friction block and the turntable are in friction transmission cooperation.

[0009] According to the above technical solution, the telescopic assembly includes a telescopic shell fixedly installed at the bottom of the mounting plate, a telescopic spring fixedly installed inside the telescopic shell, and a telescopic rod fixedly installed at the end of the telescopic spring away from the telescopic shell.

[0010] According to the above technical solution, the top of the mounting plate is equipped with an air blowing device for blowing out impurities in the cutting seam.

[0011] According to the above technical solution, the air blowing device includes a blower installed on the top of the mounting plate, a connecting pipe one at the bottom of the blower, a connecting pipe two slidably installed inside the connecting pipe one, a connecting block one rotatably installed on the left side of the bottom of the connecting pipe two, a connecting block two rotatably installed on the right side of the bottom of the connecting pipe two, a connecting plate two fixedly installed on the right side of the connecting block two, and a connecting plate one rotatably installed on the top of the connecting plate two.

[0012] According to the above technical solution, the first connecting block is fixedly connected to the second connecting plate, the first connecting plate is fixedly connected to the shearing needle, and the blower is connected to the first connecting tube and the second connecting tube.

[0013] According to the above technical solution, the bottom of the mounting plate is equipped with a striking device for striking the area near the weld seam.

[0014] According to the above technical solution, the striking device includes a fixed block fixedly installed at the bottom of the mounting plate, a rotating shaft is rotatably installed through the bottom of the fixed block, a half-tooth gear is assembled on the right side of the rotating shaft, a connecting seat is fixedly installed on the right side of the fixed block, a restoring spring is fixedly installed at the bottom of the connecting seat, and a striking rod is fixedly installed at the end of the restoring spring away from the connecting seat.

[0015] According to the above technical solution, the rotating shaft and the friction wheel are fixedly connected, the striking rod and the fixed block are slidably connected, the left side of the striking rod is provided with teeth, and the striking rod meshes with the half-tooth gear.

[0016] The advantages of this application are: (1) In this application, the friction wheel rolls in contact with the plate during the cutting process. Through the transmission of belt pulley one and belt pulley two, the meshing transmission of bevel gear one and bevel gear two, and the friction transmission of the transmission friction block and the turntable, the reciprocating screw is driven to rotate and move up and down in the mounting frame. This allows the shearing needle to rotate and move up and down simultaneously in the cutting seam, while scraping and shearing the inner wall of the cutting seam. This effectively removes unevenly distributed burrs and slag, and significantly improves the cleaning quality and smoothness of the inner wall of the cutting seam.

[0017] (2) This application sets up an air blowing device linked with the shearing needle, and uses a linkage mechanism composed of connecting plate one, connecting plate two, connecting block one and connecting block two to make the connecting pipe two slide synchronously with the up and down reciprocating motion of the shearing needle, so that the bottom outlet of the connecting pipe two always follows the cleaning position of the shearing needle, ensuring that the high-pressure airflow acts on the cutting seam area being cleaned, and blows away the scraped burrs, debris and slag in time, avoiding the residue of impurities from affecting subsequent welding or assembly processes. At the same time, the airflow cools the cutting seam, reducing the adverse effects of the heat-affected zone.

[0018] (3) This application sets up a striking device that is coaxially linked with the friction wheel. The rotating shaft drives the half-tooth gear to rotate, so that the half-tooth gear and the teeth on the striking rod periodically mesh and separate. With the elasticity of the restoring spring, the striking rod intermittently strikes the plate near the cutting seam. The impact force generated by the striking is transmitted to the inside of the plate, which helps to release the thermal stress and structural stress generated by local high temperature heating and rapid cooling during the cutting process.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0022] Example 1, as Figures 1-5As shown, a metal laser cutting machine for construction engineering based on intelligent manufacturing includes a base 100. A gantry frame 200 is fixedly mounted on the top of the base 100, providing support and a movable frame. A clamping seat 300 is provided on the top of the base 100 for firmly clamping the metal sheet to be processed. An electric moving seat 400 is provided in the middle of the gantry frame 200. An electric push rod 500 is provided on the front of the electric moving seat 400. A laser cutting head 600 is fixedly mounted on the output end of the electric push rod 500 to achieve precise laser cutting of the sheet. A mounting plate 700 is fixedly mounted on the front of the electric moving seat 400. A mounting plate 700 is fixedly mounted on the bottom of the mounting plate 700. A mounting plate 700 is equipped with a fixed plate 800, and a friction wheel 900 is rotatably mounted on the bottom of the fixed plate 800. The friction wheel 900 contacts the surface of the cutting material and rolls accordingly. A friction device 1000 is assembled on the bottom of a mounting plate 700. The friction device 1000 includes a rotating rod 1001 that passes through and is fixedly mounted in the middle of the friction wheel 900, a rotating rod 2 1005 that passes through and is rotatably mounted on the top of the fixed plate 800, a rotating rod 3 1008 that is rotatably mounted on the bottom of the mounting plate 700, a telescopic component 1010 disposed at the bottom of the mounting plate 700, and a mounting frame 1014 fixedly mounted on the bottom of the mounting plate 700. The telescopic component 1010 includes components fixedly mounted on... The telescopic housing at the bottom of the mounting plate 700 contains a telescopic spring. A telescopic rod is fixedly mounted on the end of the spring furthest from the housing, providing cushioning and pressure adjustment. A pulley 1002 is mounted on the left side of rotating rod 1001, and a pulley 1003 is mounted on the right side of rotating rod 1005. Pulleys 1002 and 1003 are connected by a drive belt 1004. A bevel gear 1006 is mounted on the left side of rotating rod 1005, and a bevel gear 1007 is mounted on the top of rotating rod 1008. The bevel gears 1006 and 1007 mesh to transmit power. The direction changes from horizontal to vertical. The bottom of the rotating rod 1008 is equipped with a transmission friction block 1009. The bottom of the telescopic component 1010 is rotatably mounted with a turntable 1011. The transmission friction block 1009 and the turntable 1011 are in friction transmission cooperation. The bottom of the turntable 1011 is fixedly mounted with a reciprocating screw 1012. The reciprocating screw 1012 is connected to the mounting frame 1014 through and rotatably. The bottom of the mounting frame 1014 is provided with an internal thread. The external thread and the internal thread of the reciprocating screw 1012 mesh with each other. When the reciprocating screw 1012 rotates, it moves up and down while rotating. The bottom of the reciprocating screw 1012 is fixedly mounted with a shearing needle 1013.During the cutting process, the friction wheel 900 rolls in contact with the plate. Through the transmission of belt pulley 1002 and belt pulley 2003, the meshing transmission of bevel gear 1006 and bevel gear 2007, and the friction transmission of transmission friction block 1009 and turntable 1011, the reciprocating screw 1012 is driven to rotate and reciprocate up and down in the mounting frame 1014. This causes the shearing needle 1013 to rotate and reciprocate up and down simultaneously in the cutting kerf, while scraping and shearing the inner wall of the cutting kerf. This effectively removes unevenly distributed burrs and slag, significantly improving the cleaning quality and smoothness of the inner wall of the cutting kerf.

[0023] In practical use, the operator first places the metal sheet to be cut stably on the clamping seat 300 at the top of the base 100, securing the sheet in place. Then, the equipment is started. The electric moving seat 400 on the gantry 200 moves horizontally according to the preset cutting path, aligning the laser cutting head 600 with the starting position of the cutting on the sheet. The electric push rod 500 controls the vertical feed of the laser cutting head 600, maintaining a suitable cutting distance between the laser cutting head 600 and the sheet surface. As the laser cutting head 600 moves along the cutting path, the electric moving seat 400 moves, causing the mounting plate 700 to move synchronously. The mounting plate 700, in turn, moves the fixing plate 800. The movement of the 800 unit drives the friction wheel 900 to move. Under the action of the electric push rod 500, the bottom of the friction wheel 900 contacts the upper surface of the metal plate. As the electric moving seat 400 continues to move downward, the friction wheel 900 fully contacts the upper surface of the metal plate. In the initial state, the telescopic spring of the telescopic component 1010 is in a naturally extended state, and the bottom of the shearing needle 1013 is slightly higher than the bottom of the friction wheel 900. When the electric moving seat 400 drives the mounting plate 700 to descend, the friction wheel 900 first contacts the surface of the plate and begins to roll. Subsequently, the bottom of the shearing needle 1013 contacts the edge of the cut seam formed on the surface of the plate. Since the bottom of the shearing needle 1013 is inserted into the cut seam, the shearing... The shearing needle 1013 moves downward a certain distance, which in turn drives the reciprocating screw 1012 to move downward a certain distance. The reciprocating screw 1012 then drives the turntable 1011 to move downward. During the downward movement of the shearing needle 1013, the outer side of the turntable 1011 contacts the outer side of the transmission friction block 1009, achieving friction transmission. The moving mounting plate 700 and the friction wheel 900's full contact with the upper surface of the metal plate cause the friction wheel 900 to rotate. The rotation of the friction wheel 900 drives the rotating rod 1001 to rotate synchronously. The rotation of the rotating rod 1001 drives the pulley 1002 to rotate. Under the transmission action of the transmission belt 1004, the pulley 1002 rotates, driving the pulley 1003 to rotate. The rotation of pulley 1003 drives the rotation of rod 1005, which in turn drives bevel gear 1006, which in turn drives bevel gear 1007, which in turn drives rod 1008, which in turn drives transmission friction block 1009. Simultaneously, transmission friction block 1009 engages in frictional transmission with turntable 1011, causing turntable 1011 to rotate. Turntable 1011 then drives reciprocating screw 1012 to rotate synchronously. During rotation, the reciprocating screw 1012, under the action of threaded engagement, also reciprocates up and down relative to mounting frame 1014.The reciprocating motion of the lead screw 1012 drives the shearing needle 1013, which is fixedly mounted at its bottom, to simultaneously rotate and reciprocate within the cutting kerf. After cleaning, the shearing needle 1013 re-contacts the surface of the plate and does not insert into the cutting kerf. Under the action of the telescopic component 1010, it drives the turntable 1011 to move upward, preparing for the next cutting kerf treatment. This friction device 1000 can effectively remove unevenly distributed burrs and slag on the inner wall of the cutting kerf. The two movements work together, enabling the shearing needle 1013 to clean the inner wall of the cutting kerf in all directions.

[0024] Example 2, as Figures 6-7 As shown, based on Embodiment 1, the top of the mounting plate 700 is equipped with an air blowing device 1100 for blowing out impurities in the cutting seam. The air blowing device 1100 includes a blower 1101 installed on the top of the mounting plate 700. A connecting pipe 1102 is provided at the bottom of the blower 1101. A connecting pipe 2 1103 is slidably installed inside the connecting pipe 1102, thereby enabling the entire airflow channel to have a certain degree of expansion and contraction adjustment capability in the vertical direction. The blower 1101 is connected to the connecting pipe 1102 and the connecting pipe 2 1103, forming a complete high-pressure airflow delivery path from the air source to the outlet. The bottom of the connecting pipe 2 1103 rotates to the left. A connecting block 1104 is movably installed, and a connecting block 2 1105 is rotatably installed on the right side of the bottom of the connecting pipe 2 1103. A connecting plate 2 1107 is fixedly installed on the right side of the connecting block 2 1105. The connecting block 1104 and the connecting plate 2 1107 are fixedly connected. A connecting plate 1106 is rotatably installed on the top of the connecting plate 2 1107. The connecting plate 1106 and the shearing needle 1013 are fixedly connected. This ensures that the connecting pipe 2 1103 and its outlet can move and adjust their posture in conjunction with the up-and-down reciprocating cleaning movement of the shearing needle 1013, so that the airflow outlet is always aligned with and follows the real-time working position of the shearing needle 1013. By setting up an air blowing device 1100 that is linked to the shearing needle 1013, and using a linkage mechanism composed of connecting plate 1106, connecting plate 2107, connecting block 1104, and connecting block 2105, the connecting tube 2103 slides synchronously with the up-and-down reciprocating motion of the shearing needle 1013. This ensures that the bottom outlet of the connecting tube 2103 always follows the cleaning position of the shearing needle 1013, ensuring that the high-pressure airflow acts on the cutting seam area being cleaned, and promptly blows away the scraped burrs, debris, and slag, avoiding impurities remaining and affecting subsequent welding or assembly processes. At the same time, the airflow cools the cutting seam, reducing the adverse effects of the heat-affected zone.

[0025] In practical use, when the electric moving seat 400 drives the mounting plate 700 to descend, and the bottom of the shearing needle 1013 is inserted into the cutting slit to clean the inner wall of the cutting slit, the shearing needle 1013 rotates up and down under the action of the friction wheel 900 in full contact with the upper surface of the metal plate. As the shearing needle 1013 rotates and reciprocates up and down in the cutting slit, the shearing needle 1013 will drive the connecting plate 1106 fixedly connected to it to move up and down and rotate synchronously during the up and down reciprocating motion. When the shearing needle 1013 moves upward under the drive of the reciprocating screw 1012, the shearing needle 1013 drives the connecting plate 1106 to move upward. The connecting plate 1106 drives the connecting tube 1103 to slide upward relative to the connecting tube 1102 through the connecting plate 2107 and the connecting block 2105, so that the bottom outlet of the connecting tube 2103 rises with the rise of the shearing needle 1013. As the shearing needle 1013 moves downward, the connecting tube 2 1103 also slides downward, ensuring that the bottom outlet of the connecting tube 2 1103 always follows the bottom position of the shearing needle 1013. After the blower 1101 is activated, it generates a high-pressure airflow. This airflow passes through the connecting tube 1 1102 and the connecting tube 2 1103 in sequence, and is ejected from the bottom outlet of the connecting tube 2 1103, directly blowing towards the cutting seam area. The ejected high-pressure airflow always acts precisely on the cutting seam area that the shearing needle 1013 is cleaning. Under the impact of the airflow, the burrs, debris, slag, and other impurities scraped off from the inner wall of the cutting seam by the shearing needle 1013 are blown away from the cutting seam and fly out to the outside of the cutting seam. At the same time, the high-pressure airflow can also cool the inside of the cutting seam to a certain extent, reducing the temperature of the cutting seam area and reducing the adverse effects of the heat-affected zone on the performance of the board.

[0026] Example 3, as Figures 8-9As shown, based on Embodiment 1, the bottom of the mounting plate 700 is equipped with a striking device 1200 for striking the area near the weld seam. The striking device 1200 includes a fixing block 1201 fixedly installed on the bottom of the mounting plate 700. A rotating shaft 1202 is rotatably mounted through the bottom of the fixing block 1201. The rotating shaft 1202 is fixedly connected to the friction wheel 900, thereby ensuring that the rotation of the rotating shaft 1202 is completely synchronized with the rotation of the friction wheel 900. A half-tooth gear 1203 is mounted on the right side of the rotating shaft 1202, and a connecting seat 12 is fixedly installed on the right side of the fixing block 1201. 04. A restoring spring 1205 is fixedly installed at the bottom of the connecting seat 1204. A striking rod 1206 is fixedly installed at the end of the restoring spring 1205 away from the connecting seat 1204. The striking rod 1206 and the fixed block 1201 are in a sliding connection relationship to ensure the stability of its movement trajectory. The striking rod 1206 and the fixed block 1201 are in a sliding connection. The left side of the striking rod 1206 is provided with teeth. The striking rod 1206 meshes with the half-tooth gear 1203 to convert the rotational motion of the friction wheel 900 into the periodic, intermittent linear striking motion of the striking rod 1206. By setting a striking device 1200 that is coaxially linked with the friction wheel 900, the rotating shaft 1202 drives the half-tooth gear 1203 to rotate, so that the half-tooth gear 1203 and the teeth on the striking rod 1206 periodically mesh and separate. With the elastic restoring effect of the recovery spring 1205, the striking rod 1206 intermittently strikes the plate near the cutting seam. The impact force generated by this striking is transmitted to the inside of the plate, which helps to release the thermal stress and structural stress generated by local high temperature heating and rapid cooling during the cutting process.

[0027] In practical use, when the electric moving base 400 lowers the mounting plate 700, and the friction wheel 900 contacts the surface of the metal plate and begins to roll, the rolling of the friction wheel 900 drives the rotating shaft 1202 to rotate synchronously. The rotation of the rotating shaft 1202 drives the half-gear 1203 to rotate. When the teeth of the half-gear 1203 rotate to the position where they mesh with the teeth of the striking rod 1206, the half-gear 1203 drives the striking rod 1206 to slide downward against the elastic force of the restoring spring 1205. The restoring spring 1205 is stretched. As the half-gear 1203 continues to rotate, when the teeth of the half-gear 1203 rotate past... When the gear 1203 is engaged and enters the toothless blank area, the engagement between the half-tooth gear 1203 and the striking rod 1206 is disengaged. At this time, the striking rod 1206 quickly rebounds upward under the elastic force of the restoring spring 1205. During the rebound process, the bottom of the striking rod 1206 strikes the surface of the board once. For each rotation of the half-tooth gear 1203, the striking rod 1206 completes one downward sliding and one upward rebound strike. The striking action can generate a certain impact force on the surface of the board. This impact force is transmitted to the interior of the board, which helps to release the thermal stress and structural stress generated during the cutting process due to local high temperature heating and rapid cooling.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
