Description

Technical Field

[0001] This invention belongs to the field of laser slag removal technology, specifically a slag removal device for laser tube cutting machines. Background Technology

[0002] Metal pipes are a common type of metal profile, widely used in various fields of production and daily life. Metal pipe manufacturers produce metal pipes in relatively long lengths (2 to 5 meters, or even longer), mainly for the convenience of production and transportation. However, in the application stage, they often need to be cut to the required length according to the usage requirements.

[0003] A patent with publication number CN112809171 discloses a slag removal device and a pipe laser cutting machine incorporating the same, belonging to the field of pipe cutting equipment. The slag removal device includes a chip removal tube, a positioning mechanism, a slider connector, a driving device for driving the slider connector to move back and forth, and a slag removal blade. The chip removal tube has a top opening at its front end; the rear end of the chip removal tube passes through the positioning mechanism and connects to the slider connector; the slag removal blade is positioned above the chip removal tube and can swing back and forth, with its front end extending into the top opening. The pipe laser cutting machine includes a connecting plate and the slag removal device described above; the slag removal device is connected to the connecting plate; the connecting plate is installed on the pipe laser cutting machine. During the backward movement of the chip removal tube, the slag removal blade automatically swings down and enters the chip removal tube through the top opening, pushing metal chips out of the chip removal tube, completing automatic cleaning without manual intervention. During the forward movement of the chip removal tube, the slag removal blade automatically swings up until its front end contacts the top surface of the chip removal tube, preventing the slag removal blade from affecting the operation of the chip removal tube.

[0004] Currently, existing laser cutting processes generate impurities such as slag and oxides. These impurities adhere to the surface of the pipe, and some oxides and slag need to be blown away by wind. However, the wind causes the molten slag to solidify rapidly, resulting in slag adhering to the steel surface, affecting cutting quality and production efficiency, and even damaging the equipment. Traditional grinding equipment can only grind the outer surface of the pipe, and cannot effectively grind the inside of the pipe. Furthermore, a single grinding device can only grind pipes of a single size, and cannot grind pipes of different sizes. In addition, the grinding device cannot make close contact with the pipe, resulting in insufficient clamping and grinding.

[0005] Therefore, the present invention provides a slag removal device for a laser tube cutting machine. Summary of the Invention

[0017] The beneficial effects of this invention are as follows: 1. The present invention provides a slag removal device for a laser pipe cutting machine, which, in conjunction with a laser cutter inside a sealed box, cuts the surface of a pipe. Simultaneously, a pair of threaded rods of a motor rotate, and a threaded slider drives a clamping push plate to push the pipe out, causing the cut-off side of the pipe to fit against the inner wall of a slag removal and grinding groove. A third motor rotates the slag removal and grinding groove, using the inner wall of the groove to grind the outer surface of the pipe. Furthermore, a second hydraulic rod pushes the slag removal and grinding groove, causing a tight compression between the groove and the pipe, increasing the contact area. 2. The slag removal device for a laser tube cutting machine described in this invention, when the slag removal and grinding groove is fitted onto the outer surface of the pipe fitting, under the continuous extrusion of the hydraulic rod, the slag removal and grinding groove will directly press against the outer surface of the pipe fitting. At this time, the slag removal and grinding groove slides on the inner wall of the limiting groove, causing the hydraulic piston rod to continuously extend and push inside the slag removal and grinding groove, and causing the extrusion and pushing groove on the outer surface of one end of the hydraulic piston rod to press against the inner wall of the slag removal and grinding groove. At this time, the arc surface on the surface of the extrusion and pushing groove is used to make one side surface of the slag removal and grinding groove tightly adhere to the inner wall of the pipe fitting, and the slag removal and grinding groove effectively extrudes and adheres to the inner and outer sides of the pipe fitting, and effectively grinds it. 3. The slag removal device for a laser tube cutting machine described in this invention, in conjunction with a second motor, rotates a second threaded rod, causing the second threaded rod to drive a slider to slide back and forth on the inner wall of a limiting groove. At this time, the overlapping support plate on the bottom surface of the slider slides the tube back and forth, allowing the tube to be connected to the entrance of the enclosed box. At this time, the first threaded rod is rotated by a second motor, causing the threaded slider on the outer surface of the first threaded rod to drive a snap-fit ​​push plate to push the tube, allowing the tube to slide from the inner wall of the swing plate. At this time, the laser cutter inside the enclosed box cuts the surface of the tube. 4. The slag removal device for a laser tube cutting machine described in this invention, when the tube inside the swing plate is pushed open, the slider will move to the top edge of the tube storage box as the threaded rod II moves. At this time, it is used in conjunction with a pair of arc-shaped overlapping grooves of the hydraulic rod to lift the tube inside the tube storage box to the bottom edge of the swing plate. Then, the tube is pressed and attached to the top outer surface of the tube by the extrusion groove on the bottom surface of the swing plate, and the swing plate is extruded and extended to both sides, and the tube is extended and clamped into the interior of the swing plate. The tube is extruded and clamped by the arc-shaped overlapping groove. 5. The slag removal device for a laser pipe cutting machine described in this invention, in conjunction with a laser cutter inside a sealed box, cuts the surface of the pipe. Simultaneously, a pair of threaded rods of a motor rotate, and a threaded slider drives a clamping push plate to push the pipe out, causing the cut-off side of the pipe to fit against the inner wall of the slag removal and grinding groove. A third motor rotates the slag removal and grinding groove, using the inner wall of the groove to grind the outer surface of the pipe. Under the push of a second hydraulic rod, the slag removal and grinding groove and the pipe are tightly pressed together, increasing the contact area. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 6 As shown, an embodiment of the present invention provides a slag removal device for a laser tube cutting machine, comprising a laser tube cutting processing table 11 and a closed box 12 fixedly installed on one side surface of the laser tube cutting processing table 11, a hydraulic rod 13 fixedly installed on one side surface of the closed box 12, a pipe fitting 14 movably sleeved on the inner wall of the laser tube cutting processing table 11, a slider 15 slidably sleeved on the top surface of the laser tube cutting processing table 11, a motor 111 fixedly installed on the other side surface of the laser tube cutting processing table 11, a threaded rod 112 fixedly connected to the output end of the motor 111, a threaded slider 113 threadedly and movably sleeved on the outer surface of the threaded rod 112, a snap-fit ​​push plate 114 movably overlapping the surface of the pipe fitting 14 fixedly connected to the top surface of the threaded slider 113, and a laser cutter 1110 provided on the inner wall of the closed box 12. A motor 131 is fixedly connected to the output end of the hydraulic rod 2 13, and a hydraulic piston rod 132 is fixedly connected to the output end of the motor 3 131. A slag removal and grinding groove 136 is movably sleeved on the outer surface of the hydraulic piston rod 132.

[0023] The laser cutter 1110 inside the enclosed box 12 cuts the surface of the pipe fitting 14. At this time, the motor 111 rotates the threaded rod 112, and the threaded slider 113 drives the snap-fit ​​push plate 114 to push the pipe fitting 14 out, so that the cut side of the pipe fitting 14 fits into the inner wall of the slag removal and grinding groove 136. The motor 31 rotates the slag removal and grinding groove 136, and the inner wall of the slag removal and grinding groove 136 grinds the outer surface of the pipe fitting 14. Under the push of the hydraulic rod 213, the slag removal and grinding groove 136 and the pipe fitting 14 are tightly squeezed to increase the contact area. When the slag removal and polishing groove 136 is fitted onto the outer surface of the pipe fitting 14, under the continuous compression of the hydraulic rod 13, the slag removal and polishing groove 136 will directly press against the outer surface of the pipe fitting 14. At this time, the slag removal and polishing groove 136 slides on the inner wall of the limiting groove 133, causing the hydraulic piston rod 132 to continuously extend and push inside the slag removal and polishing groove 136. This causes the compression and pushing groove 135 on the outer surface of one end of the hydraulic piston rod 132 to press against the inner wall of the slag removal and polishing groove 136. At this time, the arc surface on the surface of the compression and pushing groove 135 is used to make one side surface of the slag removal and polishing groove 136 tightly adhere to the inner wall of the pipe fitting 14. The slag removal and polishing groove 136 effectively compresses and adheres to the inner and outer sides of the pipe fitting 14, and effectively polishes it.

[0024] like Figures 1 to 6As shown, a limiting groove 133 is formed on the outer surface of the hydraulic piston rod 132. The outer surface of the slag removal and grinding groove 136 is movably sleeved on the inner wall of the limiting groove 133. Elastic wires 134 are fixedly connected to the inner walls on both sides of the limiting groove 133. The other end of the elastic wires 134 is fixedly connected to the outer surface of the slag removal and grinding groove 136. A swing-fitting arc plate 137 is formed on the outer surface of the slag removal and grinding groove 136. A pressing and pushing groove 135 is formed on one end of the hydraulic piston rod 132. The outer surface of the moving groove 135 is movably connected to the inner wall of the slag removal and grinding groove 136. Pipe storage boxes 115 are fixedly installed on both sides of the laser tube cutting processing table 11. A support frame 116, which is set on the top surface of the laser tube cutting processing table 11, is fixedly installed on the outer surface of the pipe storage box 115. A second motor 118 is fixedly installed on one side of the support frame 116. A threaded rod 119 is fixedly connected to the output end of the second motor 118. A limit switch is provided on the top surface of the support frame 116. The outer and bottom surfaces of the slide groove 117 and the slider 15 are respectively movably fitted onto the outer surface of the threaded rod 119 and the inner wall of the limiting slide groove 117. An overlapping support plate 151 is fixedly connected to the bottom side of the slider 15, movably overlapping the inner wall of the top of the support frame 116. A swing plate 152 is fixedly connected to the bottom surface of the overlapping support plate 151. An arc-shaped fitting groove 153 is formed on the inner wall of the swing plate 152, movably fitting onto the outer surface of the pipe fitting 14. A compression groove 155 is provided on the bottom surface of 2. A compression limiting soft strip 154 ​​is fixedly connected to the outer surface of the swing plate 152. An overlap plate a1 is provided on the outer surface of the pipe fitting storage box 115. A flow-driving groove a2 is provided on one side surface of the overlap plate a1. A hydraulic rod a3 is fixedly installed on the bottom inner wall of the pipe fitting storage box 115. An overlap blocking plate a4 is fixedly connected to the output end of the hydraulic rod a3. An arc-shaped overlap groove a5 is opened on the top surface of the overlap blocking plate a4.

[0025] The second motor 118 rotates the second threaded rod 119, causing the second threaded rod 119 to drive the slider 15 to slide back and forth on the inner wall of the limiting groove 117. At this time, the overlapping support plate 151 on the bottom surface of the slider 15 slides the pipe 14 back and forth, allowing the pipe 14 to dock with the entrance of the enclosed box 12. At this time, the first motor 111 rotates the first threaded rod 112, causing the threaded slider 113 on the outer surface of the first threaded rod 112 to drive the snap-fit ​​push plate 114 to push the pipe 14, allowing the pipe 14 to slide from the inner wall of the swing plate 152. At this time, the laser cutter 1110 inside the enclosed box 12 cuts the surface of the pipe 14. When the pipe 14 inside the swing plate 152 is pushed open, the slider 15 will move to the top edge of the pipe storage box 115 as the threaded rod 119 moves. At this time, the hydraulic rod a3 will lift the arc-shaped lap groove a5 to lift the pipe 14 inside the pipe storage box 115 to the bottom edge of the swing plate 152. Then, the extrusion groove 155 on the bottom surface of the swing plate 152 will press and adhere it to the top outer surface of the pipe 14, and the swing plate 152 will be extruded and extended to both sides, and the pipe 14 will be extended and inserted into the interior of the swing plate 152. The arc-shaped fitting groove 153 will be used to extrude and clamp the pipe 14. The laser cutter 1110 inside the enclosed box 12 cuts the surface of the pipe fitting 14. At this time, the motor 111 rotates the threaded rod 112, and the threaded slider 113 drives the snap-fit ​​push plate 114 to push the pipe fitting 14 out, so that the cut side of the pipe fitting 14 fits into the inner wall of the slag removal and grinding groove 136. The motor 31 rotates the slag removal and grinding groove 136, and the inner wall of the slag removal and grinding groove 136 grinds the outer surface of the pipe fitting 14. Under the push of the hydraulic rod 213, the slag removal and grinding groove 136 and the pipe fitting 14 are tightly squeezed to increase the contact area. When the slag removal and polishing groove 136 is fitted onto the outer surface of the pipe fitting 14, under the continuous extrusion of the hydraulic rod 13, the slag removal and polishing groove 136 will directly press against the outer surface of the pipe fitting 14. At this time, the slag removal and polishing groove 136 slides on the inner wall of the limiting groove 133, causing the hydraulic piston rod 132 to continuously extend and push inside the slag removal and polishing groove 136, and causing the extrusion and pushing groove 135 on the outer surface of one end of the hydraulic piston rod 132 to press against the inner wall of the slag removal and polishing groove 136. At this time, the arc surface on the outer surface of the extrusion and pushing groove 135 is used to make one side surface of the slag removal and polishing groove 136 tightly adhere to the inner wall of the pipe fitting 14, and the slag removal and polishing groove 136 effectively extrudes and adheres to the inner and outer sides of the pipe fitting 14, and effectively polishes it. When the leftmost pipe fitting 14 moves to the surface of the snap-fit ​​push plate 114, the snap-fit ​​push plate 114 snaps and positions the current pipe fitting 14, and under the push of the threaded slider 113, the pipe fitting 14 is moved into the interior of the enclosed box 12 for cutting. After the leftmost pipe fitting 14 is cut, it moves layer by layer to the left under the drive of the slider 15. When the swing plate 152 moves to the top surface of the pipe fitting storage box 115, it cooperates with the hydraulic rod a3 to squeeze and clamp the interior of the swing plate 152. The connecting fitting 14 fills the interior of the empty swing plate 152 with the fitting 14. As the overlapping support plate 151 moves to the right, the swing plate 152, after being filled with the fitting 14, can continuously cut the fitting 14. When the overlapping support plate 151 moves back and forth on the top surface of the snap-fit ​​push plate 114, the fitting storage boxes 115 on both sides can fill the interior of the swing plate 152 with the fitting 14, so that the swing plate 152 can be continuously filled with new fittings 14 and is always in a laser cutting state.

[0026] Working principle: The second motor 118 rotates the second threaded rod 119, causing the second threaded rod 119 to drive the slider 15 to slide back and forth on the inner wall of the limiting groove 117. At this time, the overlapping support plate 151 on the bottom surface of the slider 15 slides the pipe 14 back and forth, allowing the pipe 14 to dock with the entrance of the enclosed box 12. At this time, the first motor 111 rotates the first threaded rod 112, causing the threaded slider 113 on the outer surface of the first threaded rod 112 to drive the snap-fit ​​push plate 114 to push the pipe 14, allowing the pipe 14 to slide from the inner wall of the swing plate 152. At this time, the laser cutter 1110 inside the enclosed box 12 cuts the surface of the pipe 14. When the pipe 14 inside the swing plate 152 is pushed open, the slider 15 will move to the top edge of the pipe storage box 115 as the threaded rod 119 moves. At this time, the hydraulic rod a3 will lift the arc-shaped lap groove a5 to lift the pipe 14 inside the pipe storage box 115 to the bottom edge of the swing plate 152. Then, the extrusion groove 155 on the bottom surface of the swing plate 152 will press and adhere it to the top outer surface of the pipe 14, and the swing plate 152 will be extruded and extended to both sides, and the pipe 14 will be extended and inserted into the interior of the swing plate 152. The arc-shaped fitting groove 153 will be used to extrude and clamp the pipe 14. When the leftmost pipe fitting 14 moves to the surface of the snap-fit ​​push plate 114, the snap-fit ​​push plate 114 snaps and positions the current pipe fitting 14, and under the push of the threaded slider 113, the pipe fitting 14 is moved into the interior of the enclosed box 12 for cutting. After the leftmost pipe fitting 14 is cut, it moves layer by layer to the left under the drive of the slider 15. When the swing plate 152 moves to the top surface of the pipe fitting storage box 115, it cooperates with the hydraulic rod a3 to squeeze and clamp the interior of the swing plate 152. The connecting fitting 14 fills the interior of the empty swing plate 152 with the fitting 14. As the overlapping support plate 151 moves to the right, the swing plate 152, after being filled with the fitting 14, can continuously cut the fitting 14. When the overlapping support plate 151 moves back and forth on the top surface of the snap-fit ​​push plate 114, the fitting storage boxes 115 on both sides can fill the interior of the swing plate 152 with the fitting 14, so that the swing plate 152 can be continuously filled with new fittings 14 and is always in a laser cutting state.
