Description

Technical Field

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

[0002] Pipe fittings are a general term for parts in pipeline systems that play roles in connection, control, direction change, diversion, sealing, and support. Metal pipe fittings are usually cut using laser cutting machines during production. Laser cutting machines focus the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam is irradiated onto the surface of metal pipe fittings to make the metal pipe fittings reach their melting point or boiling point. At the same time, high-pressure gas coaxial with the beam will melt or vaporize the metal to achieve cutting of the metal pipe fittings.

[0003] A patent with publication number CN113695763B discloses a laser cutting machine for separating and processing metal pipes. The patent separates the metal pipes by setting a separation baffle, and the transfer roller and the drive roller drive the metal pipes for transportation. The laser cutting head at the bottom of the laser body is used to cut the metal pipes. The position of the mounting plate on the mounting bracket rod is adjusted by a movable sleeve. The laser measurement sensor at the bottom of the detection plate is used to measure the metal pipes waiting to be inserted into the cutting body. When the subsequent metal pipes do not meet the cutting requirements, the drive roller rotates in the opposite direction to push out the metal pipes, and the telescopic cylinder contracts, so that the distance between the support roller and the transfer roller on the telescopic frame is increased, and the metal pipes fall into the residual material bin for collection, which facilitates the cutting of metal pipes and improves work efficiency.

[0004] There are still some problems in the actual application of the above scheme. Usually, a metal pipe is placed on a bracket, and then the bracket is used to drive the metal pipe to rotate. At the same time, the head of the laser cutting machine is controlled to fit or approach the metal pipe. Then, during the rotation of the metal pipe, the head of the laser cutting machine is used to emit laser to cut the metal pipe. However, this cutting method can only cut a single metal pipe at a time, which not only affects the cutting efficiency of the metal pipe, but also the cut metal pipe is affected by the bracket, which makes it inconvenient to collect it quickly, which will also affect the subsequent cutting processing of the metal pipe.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The metal pipe laser cutting machine described in the present invention drives the laser cutting head to move downward by driving the push plate, so that the laser cutting head slides into the through opening to focus on the metal pipe, and at the same time drives the pressing plate to position and press the metal pipe in the semicircular limit groove to keep it stable, and the latex pad on the lower end surface of the pressing plate can be deformed according to the metal pipe, ensuring the pressing force and forming an independent space in the through opening, and then the laser cutting head is used to emit laser to cut the metal pipe, and the smoke and sparks generated during the cutting of the metal pipe will only be sputtered in the independent space, thereby preventing the sparks from sputtering out of the laser cutting machine to cause fire and other safety hazards, and also preventing the sparks from sputtering onto the operator, causing harm to the operator's safety.

The power distribution block 18 is powered on, and the power distribution block 18 uses the wire 21 to power the laser cutting machine body 20, so that the laser cutting head 22 cuts the metal pipe 11, and the laser emitted by the laser cutting head 22 is kept on the same vertical line as the semicircular limit groove 12, and then the length of the metal pipe 11 is pushed out of the semicircular limit groove 12, which is the metal pipe 11 that needs to be processed and cut, and the processed and cut metal pipe 11 will fall into the inner cavity of the workbench 1, and then be discharged and quickly collected through the discharge port 2, thereby realizing the simultaneous processing and production of multiple metal pipes 11, improving the efficiency of metal pipe processing and production, and being able to quickly collect the cut metal pipes 11, thereby solving the above-mentioned problem.

[0043] like Figure 5 , Figure 6 and Figure 8 As shown, the lower end surface of the push plate 17 is provided with receiving grooves 31 at the four corners, the inner cavity of the receiving groove 31 is slidably connected with a T-shaped sliding column 29, the lower end of the T-shaped sliding column 29 is fixedly connected to the pressing plate 24, and the lower end surface of the pressing plate 24 is provided with a latex pad.

[0044] like Figure 6 and Figure 8 As shown, a spring 30 is fixed to the bottom of the inner cavity of the storage groove 31, one end of the spring 30 is fixed to the pressing plate 24, a plurality of through openings 25 are evenly opened on the lower end surface of the pressing plate 24, two limit sliding columns 8 are symmetrically installed on the upper end surface of the push plate 17, and the two limit sliding columns 8 are slidably connected to the mounting frame 6.

[0045] Specifically, by pre-aligning multiple metal pipe fittings 11 and pushing them into the semicircular limiting groove 12, the length of the metal pipe fitting 11 is pushed into the inner cavity of the workbench 1 using one end of the semicircular limiting groove 12 as a base point, and then the metal pipe fitting 11 that needs to be cut and processed this time is pushed downward by driving the pushing plate 17, and the pushing plate 17 uses the T-shaped sliding column 29 to drive the pressing plate 24 to move downward, and at the same time, the pressing plate 24 uses the latex pad to press the metal pipe fitting 11 in the inner cavity of the semicircular limiting groove 12 to keep it stable, and the latex pad can be deformed according to the metal pipe fitting 11 to ensure the pressing force, and then as the pushing plate 17 continues to move downward, the pressing plate 24 will push the T-shaped sliding column 29 to slide in the inner cavity of the storage groove 31, and at the same time squeeze the spring 30 to be stored in the inner cavity of the storage groove 31, and at this time, the pushing plate 17 The plate 17 pushes the laser cutting machine body 20 to drive the laser cutting head 22 to slide into the inner cavity of the through opening 25, and then fits with the surface of the metal pipe 11, and then uses the laser cutting head 22 to emit laser to cut the metal pipe 11, thereby ensuring the stability of the metal pipe 11 during cutting, and the smoke and sparks generated by the laser cutting head 22 when cutting the metal pipe 11 will only be sputtered in the inner cavity of the through opening 25, thereby preventing the sparks generated by the cutting from sputtering out of the laser cutting machine and causing safety hazards such as fire, and also preventing the sparks from sputtering onto the operator, thereby solving the problem that when the existing laser cutting machine is cutting metal pipes, if the sparks generated during the cutting process are not protected, the sparks generated by the cutting will sputter out of the laser cutting machine and cause safety hazards such as fire, and will also endanger the safety of the operator.

Since the bottom of the inner cavity of the receiving trough 23 is arranged as an inclined material guide wall, after the metal pipe 11 falls into the inner cavity of the receiving trough 23, it will be guided to be discharged and collected through the discharge port 2, thereby solving the problem that when the existing laser cutting machine cuts the metal pipe, the metal will be melted or vaporized at high temperature due to laser cutting of the metal pipe, and then quickly cooled and solidified into tiny metal particles. These particles are metal dust. If the operator inhales a large amount of smoke containing metal dust for a long time, it will cause safety hazards to the lungs and other health.

[0052] like Figure 2 and Fig. 9 As shown, a plurality of through slots 56 are provided between the first slide bar 53 and the second slide bar 54, and a pulley 57 is rotatably connected to the inner cavity of each through slot 56, and a plurality of rubber anti-skid tooth blocks are evenly arranged on the outside of the pulley 57. A micro motor 55 is arranged on one side of the first slide bar 53, and the output shaft end of the micro motor 55 is fixedly connected to the pulley 57.

[0053] Specifically, the plurality of metal pipes 11 are conveyed into the inner cavity of the semicircular limiting groove 12, and the plurality of metal pipes 11 are abutted against the first slide bar 53 and the second slide bar 54, so that the plurality of metal pipes 11 are kept in the same plane, and then the bidirectional threaded rod 52 is driven to rotate, and the bidirectional threaded rod 52 is threaded to drive the first slide bar 53 and the second slide bar 54 to move away from each other. After the first slide bar 53 and the second slide bar 54 are opened away from each other, the screw rod 4 is driven to rotate, and the screw rod 4 is threaded to drive the sliding frame 51 to the inner cavity of the mounting frame 6. The first slide bar 53 and the second slide bar 54 slide to the outside of the metal pipe 11, and then the bidirectional threaded rod 52 is driven to rotate, and the bidirectional threaded rod 52 is threaded to drive the first slide bar 53 and the second slide bar 54 to move closer to each other, so that the first slide bar 53 and the second slide bar 54 drive the pulley 57 to clamp and fix the metal pipe 11, and at the same time, the screw rod 4 is driven to rotate, and the screw rod 4 is threaded to drive the sliding frame 51 to move toward the fixed frame 3, so that the first slide bar 53 and the second slide bar 54 drive the metal pipe 11 to move closer to each other. The pipe fitting 11 moves synchronously, and after the first slide bar 53 and the second slide bar 54 drive the metal pipe fitting 11 to move to the required cutting length, the screw rod 4 is stopped from rotating, and then the micro motor 55 is started to drive the pulley 57 to rotate, and the pulley 57 is evenly provided with a plurality of rubber anti-skid tooth blocks on the outside, so that the pulley 57 drives the metal pipe fitting 11 to rotate, and then cooperates with the laser cutting head 22 to cut the metal pipe fitting 11, and after the metal pipe fitting 11 is cut, by driving the bidirectional threaded rod 52 to rotate, the first slide bar 53 and the second slide bar 54 are threadedly driven to move away from each other, so that the cut metal pipe fitting 11 falls into the inner cavity of the receiving trough 23 for collection, thereby realizing rapid cutting of the metal pipe fitting, and solving the problem that when the existing laser cutting machine cuts multiple metal pipe fittings, it is inconvenient to drive the metal pipe fittings to rotate, so that the laser cutting head cannot effectively cut off the metal pipe fittings, and increasing the power of the laser cutting machine will cause the laser power emitted by the laser cutting machine to be too large to penetrate the metal pipe fittings and damage the workbench.

[0054] like Figure 1 and Figure 7 As shown, a plurality of partitions 15 are fixedly connected to the upper wall of the inner cavity of the mounting frame 6 , a plurality of plug posts 14 are arranged on both sides of the lower end of the mounting frame 6 , and the mounting frame 6 is plugged and installed with the workbench 1 through the plug posts 14 .

[0055] like Figures 1 to 3 As shown, a plurality of partition blocks 10 are installed on one side of the upper end surface of the workbench 1, and a limit frame 9 is installed on both end surfaces of the plurality of partition blocks 10. One end of the limit frame 9 is fixedly installed with the mounting frame 6, and a plurality of balls are evenly arranged in the inner cavity of the semicircular limit groove 12.

[0056] The working principle is as follows: by conveying the plurality of metal pipe fittings 11 into the inner cavity of the semicircular limiting groove 12, and making the plurality of metal pipe fittings 11 abut against the first slide bar 53 and the second slide bar 54, the plurality of metal pipe fittings 11 are kept in the same plane, and then the bidirectional threaded rod 52 is driven to rotate, and the bidirectional threaded rod 52 thread-drives the first slide bar 53 and the second slide bar 54 to move away from each other. After the first slide bar 53 and the second slide bar 54 are opened away from each other, the screw rod 4 is driven to rotate, and the screw rod 4 thread-drives the sliding frame 51 to move into the inner cavity of the mounting frame 6, so that the first slide bar 53 and the second slide bar 54 slide to the outside of the metal pipe fitting 11, and then the bidirectional threaded rod 52 is driven to rotate, and the bidirectional threaded rod 52 thread-drives the first slide bar 53 and the second slide bar 54 to move away from each other. The rod 52 threadedly drives the first slide bar 53 and the second slide bar 54 to move closer to each other, so that the first slide bar 53 and the second slide bar 54 drive the pulley 57 to clamp and fix the metal pipe 11, and at the same time, the screw rod 4 is driven to rotate, and the screw rod 4 threadedly drives the sliding frame 51 to move toward the fixed frame 3, so that the first slide bar 53 and the second slide bar 54 drive the metal pipe 11 to move synchronously, and after the first slide bar 53 and the second slide bar 54 drive the metal pipe 11 to move to the required cutting length, the screw rod 4 is stopped from rotating, and then the micro motor 55 is started to drive the pulley 57 to rotate, and the pulley 57 is evenly provided with a plurality of rubber anti-skid tooth blocks on the outside, so that the pulley 57 drives the metal pipe 11 to rotate;

At the same time, the pressing plate 24 uses the latex pad to press the metal pipe 11 in the inner cavity of the semicircular limiting groove 12 to keep it stable. The latex pad can be deformed according to the metal pipe 11 to ensure the pressing force. Then, as the push plate 17 continues to move downward, the pressing plate 24 will push the T-shaped slide column 29 to slide in the inner cavity of the storage groove 31, and at the same time squeeze the spring 30 to be stored in the inner cavity of the storage groove 31. At this time, The push plate 17 pushes the laser cutting machine body 20 to drive the laser cutting machine head 22 to slide into the inner cavity of the through opening 25, and then fits with the surface of the metal pipe 11, and then uses the laser cutting machine head 22 to emit laser to cut the metal pipe 11, so as to ensure the stability of the metal pipe 11 during cutting, and the smoke and sparks generated by the laser cutting machine head 22 when cutting the metal pipe 11 will only be sputtered in the inner cavity of the through opening 25, thereby preventing the sparks generated by the cutting from sputtering out of the laser cutting machine to cause fire and other safety hazards, and also preventing the sparks from sputtering onto the operator;

[0058] When the metal pipe 11 is cut by the laser cutting head 22, the dust suction port 28 is connected to an external dust collector for installation. A small vacuum cleaner or exhaust fan can also be installed at the dust suction port 28 according to actual usage. The vacuum cleaner is then used to exhaust air through the dust suction port 28, while extracting the air in the inner cavity of the air guide groove 27, and the dust extraction hole 26 is used to extract the air in the inner cavity of the opening 25. The sparks and smoke generated by the cutting of the metal pipe 11 are drawn into the inner cavity of the air guide groove 27 through the dust extraction hole 26, and then extracted and collected through the dust suction port 28. The cut metal pipe 11 will fall into the inner cavity of the receiving trough 23. Since the bottom of the inner cavity of the receiving trough 23 is arranged as an inclined material guide wall, after the metal pipe 11 falls into the inner cavity of the receiving trough 23, it will be guided to be discharged and collected through the discharge port 2.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
