Description

Technical Field

[0001] The present invention relates to the technical field of flame cutting machine tools, and specifically relates to a splash-proof automatic flame cutting device. Background Art

[0002] At present, the cutting of large pipe fittings is generally carried out using a pipe flame cutting machine. The pipe is placed on a roller rack, and the rollers rotate to drive the pipe to rotate through friction. After the pipe rotates one week, the cutting machine completes the cutting of it.

[0003] Application No. CN202110945907.5 discloses a flame cutting device for circular pipe processing. Through a sliding drive motor on the cutting block and a rack cooperating with the sliding drive motor, the cutting block slides on the guide rail member, and by using a laser alignment component arranged on the cutting block, the cutting block is located at the position to be cut in the pipe to be cut.

[0004] During use, the surface of the pipe fitting will rust. When the rusty pipe fitting is cut, since the rusty substance will interfere with the cutting flame, the cut will be relatively blurred. Moreover, there will still be some rusty substances remaining on the cut after cutting, which will affect subsequent processing and use. The existing flame cutting devices do not have the function of removing rust from the surface of the pipe fitting, and there are still certain defects in actual use. Summary of the Invention

The one-way rotation directions of the driving ratchet I and the driving ratchet II are arranged in opposite directions.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. Drive the rotating shaft to rotate through a brake stepping motor, so that the driving ratchet wheel 1 drives the limiting tooth ring and several limiting gear wheels to rotate, so that several auxiliary rollers and driving rollers arranged at equal angles inside the cavity ring rotate synchronously, thereby driving the grinding abrasive belt to rotate synchronously, so as to be able to comprehensively wrap and effectively automatically grind and remove rust on the surface to be cut of the pipe fitting, ensure the overall cutting quality, avoid affecting subsequent processing and use. At the same time, when the limiting tooth ring rotates, it will drive several abutting blocks on the side to rotate synchronously, thereby abutting against the roller rod, making the roller rod reciprocate. At the same time, with the settings of the liquid storage tank, diversion ring, limiting box, piston block, return spring, one-way liquid inlet valve pipe and one-way liquid discharge valve pipe, when the roller rod reciprocates, a certain amount of rust remover inside the liquid storage tank can be intermittently sprayed from the nozzle onto the surface of the rotating grinding abrasive belt, so that the overall grinding and rust removal effect is better and the efficiency is improved;

[0018] 2. Contact the conductive copper ring with the conductive rotating ring of the external power supply, so that the heating rod inside the auxiliary roller generates a certain amount of heat, so that the grinding abrasive belt in contact with the auxiliary roller also has a certain temperature. At the same time, with the heat generated by the grinding abrasive belt itself during grinding, the surface of the pipe fitting to be cut can be preheated in advance, so that the pipe fitting after preheating can be heated to the ignition point faster during subsequent cutting, obtaining a higher cutting speed and improving the overall cutting efficiency;

[0019] 3. Through the wrapping and covering of the cavity ring, rotating ring and limiting ring, the flame generated during the rotary cutting of the flame cutting assembly will not splash, and the safety is high. At the same time, when the rotating ring drives the flame cutting assembly to perform rotary cutting, the insulating block at the bottom of the rotating ring rotates and moves away from between the conduction block 1 and the conduction block 2, so that the compression spring rebounds, and the conduction block 1 and the conduction block 2 are conducted. The electromagnet ring 1 is energized to repel the magnet ring 2, so that the piston ring compresses and injects the gas inside the gas collecting cavity into the annular airbag, causing it to expand and wrap and isolate the side of the pipe fitting, so as to prevent some fine metal dust from splashing out from the side during cutting and diffusing in the workshop air to cause pollution, ensuring the isolation and anti-splash effect of metal dust impurities. When the cutting is completed, the insulating block rotates and resets to between the conduction block 1 and the conduction block 2 again, and the electromagnet ring 1 is powered off. At this time, the tension spring drives the piston ring to move back, and the gas inside the annular airbag is pumped back into the gas collecting cavity again, causing the annular airbag to recover and deflate, so that when the cut pipe is removed, it will not contact and rub against the surface of the annular airbag, preventing the cut from scratching the surface of the annular airbag, thereby extending the service life of the annular airbag.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1-12 , the present invention provides a technical solution: an anti-spatter automatic flame cutting device, including a cutting table 1, a pipe conveying assembly 2 and a pipe output assembly 3 are symmetrically installed at the top of the cutting table 1, a cavity ring 4 is arranged between the pipe conveying assembly 2 and the pipe output assembly 3, and the bottom end of the cavity ring 4 is fixed to the top side of the cutting table 1 through a bracket. A rotating ring 5 is rotatably engaged and installed outside one side of the cavity ring 4 close to the pipe output assembly 3. A flame cutting assembly 6 is fixedly penetrated through the outside of one side of the rotating ring 5. A limiting ring 7 is rotatably engaged and installed on the other side of the rotating ring 5, and the bottom end of the limiting ring 7 is also fixed to the top side of the cutting table 1 through a bracket. A brake stepping motor 8 is installed on one side of the top of the cutting table 1, and a rotating shaft 9 is coaxially fixed to the output end of the brake stepping motor 8. A rust removal mechanism 10 is arranged inside the cavity ring 4, and an isolation mechanism 12 is arranged inside the limiting ring 7.

[0035] In this embodiment, the anti-spatter automatic flame cutting device mainly includes a cutting table 1, a pipe conveying component 2, a pipe output component 3, a flame cutting component 6 and a rust removal mechanism 10. When the anti-spatter automatic flame cutting device provided in this solution is actually used, first, the pipe fittings to be cut are placed between the pipe conveying component 2, the pipe output component 3, the cavity ring 4, the rotating ring 5 and the limiting ring 7. Then, the pipe conveying component 2 and the pipe output component 3 composed of existing structures are used to convey the pipe fittings. During the conveying process, by starting the brake stepping motor 8 on one side, the rotating shaft 9 on one side can be driven to rotate forward by the brake stepping motor 8, thereby triggering the rust removal mechanism 10 on one side to start running. Through the operation of the rust removal mechanism 10, the automatic grinding and rust removal of the cutting surface of the pipe fittings can be effectively carried out in a comprehensive manner, ensuring the overall cutting quality in the later stage. The overall operation is automatic, the operation is convenient, and the use effect is good. At the same time, through the wrapping and covering of the cavity ring 4, the rotating ring 5 and the limiting ring 7, the flame generated during the rotary cutting of the flame cutting component 6 will not splash, with high safety and good overall use effect.

[0036] In some embodiments, the rust removal mechanism 10 includes a partition plate 1001, an auxiliary roller 1002, a driving roller 1003 and a grinding sand belt 1004. A number of partition plates 1001 are fixedly arranged at equal intervals around the middle position inside the cavity ring 4. A plurality of groups of symmetric auxiliary rollers 1002 are rotatably installed at equal angles around the inner wall of the cavity ring 4 near the center position. A driving roller 1003 is arranged on one side of each group of symmetrically arranged auxiliary rollers 1002, and the driving roller 1003 is rotatably installed through the inner part of the cavity ring 4 on the side far from the auxiliary roller 1002. A grinding sand belt 1004 is sleeved and attached to the outside between each group of symmetrically arranged auxiliary rollers 1002 and the separately arranged driving roller 1003; the rust removal mechanism 10 further includes a limiting gear 1005, a limiting tooth ring 1006 and a driving ratchet 1007. Limiting gears 1005 are fixedly arranged at the rotating through ends on one side of the driving roller 1003. A limiting tooth ring 1006 is rotatably clamped and installed outside the cavity ring 4 near the limiting gear 1005. A driving ratchet 1007 is meshed and connected to the bottom side of the limiting tooth ring 1006, and the driving ratchet 1007 is installed through the outside of one side of the rotating shaft 9.

[0037] Combined with Figure 3 and Figure 4As shown, the brake stepping motor 8 drives the rotation of the rotating shaft 9 on one side in the positive direction, thereby driving the synchronous rotation of the driving ratchet wheel 1007 outside the rotating shaft 9, and then driving the rotation of the limiting tooth ring 1006 engaged on one side, and further driving the synchronous rotation of a plurality of limiting gears 1005 engaged on the side of the limiting tooth ring 1006, driving the rotation of a plurality of driving rollers 1003 and auxiliary rollers 1002 outside the cavity ring 4, so that the grinding abrasive belts 1004 outside the driving rollers 1003 and auxiliary rollers 1002 start to rotate, thereby enabling the automatic grinding and rust removal of the surface to be cut of the pipe fitting to be comprehensively wrapped and effectively ensuring the overall cutting quality, avoiding affecting subsequent processing and use. The overall rust removal is relatively comprehensive, with high efficiency and good use effect.

[0038] In some embodiments, the rust removal mechanism 10 further includes a contact block 1008, a limit box 1011, a piston block 1012, a roller rod 1013 and a return spring 1014. A plurality of contact blocks 1008 are fixedly arranged around the outside of the limit tooth ring 1006 at equal angles. Limit boxes 1011 are fixedly arranged at the edge of one side of the cavity ring 4 close to the contact blocks 1008. A piston block 1012 is slidably and sealingly installed inside the limit box 1011. A roller rod 1013 is longitudinally and slidably installed through the bottom end of the limit box 1011, and the top end of the roller rod 1013 is fixedly installed with the bottom end side of the piston block 1012. A return spring 1014 is sleeved and connected to the outside of one side of the roller rod 1013. The side of the contact block 1008 close to the roller rod 1013 is arranged in an arc-shaped slope. The rust removal mechanism 10 further includes a liquid storage tank 1009, a diversion ring 1010, a one-way liquid inlet valve pipe 1015, a one-way liquid discharge valve pipe 1016 and a spray head 1017. A liquid storage tank 1009 is fixed to the top side of the cavity ring 4 through a bracket, and a diversion ring 1010 is fixed to the outside of the bottom end of the cavity ring 4 close to the liquid storage tank 1009 through a bracket, and the top end of the diversion ring 1010 is connected to the bottom end of the liquid storage tank 1009 in a conducting manner. A one-way liquid inlet valve pipe 1015 is conductively installed on the outside of the top end side of the limit box 1011, and the input end of the one-way liquid inlet valve pipe 1015 is conductively connected to the inside of one side of the diversion ring 1010. A one-way liquid discharge valve pipe 1016 is conductively installed on the other side of the top end of the limit box 1011, and the one-way liquid discharge valve pipe 1016 is installed through and conductively on the outside of the top end side of the driving roller 1003, and a spray head 1017 is conductively installed on the outside of one side of the top end of the driving roller 1003 where the one-way liquid discharge valve pipe 1016 is located.

[0039] Combined with Figure 5 and Figure 6As shown, when the limiting gear ring 1006 rotates, it will drive several side resistance blocks 1008 to rotate synchronously. As the slope of the resistance block 1008 changes, it will resist the roller rod 1013 to be lifted and moved, so that the roller rod 1013 resists the piston block 1012 inside the limiting box 1011 and is lifted synchronously, so that the anti-rust liquid originally drawn into the limiting box 1011 is squeezed into the inside of the one-way drain valve pipe 1016 and then sprayed out through the nozzle 1017 onto the surface of the running grinding belt 1004, thereby making the overall grinding and rust removal effect better and improving efficiency.

[0040] When the resistance block 1008 rotates and moves to a certain position, it disengages from the roller rod 1013. At this time, the return spring 1014 rebounds, thereby driving the roller rod 1013 and the piston block 1012 to move downward to generate suction. At the same time, the one-way liquid inlet valve tube 1015 and the guide ring 1010 are connected, so that the anti-rust liquid originally injected into the liquid storage tank 1009 is absorbed into the interior of the limit box 1011 to ensure subsequent spraying and supply. According to the above working steps, the roller rod 1013 can perform reciprocating lifting and lowering movements, so that the grinding belt 1004 can be sprayed with small doses intermittently and continuously to ensure the overall grinding and rust removal effect.

[0041] In some embodiments, an auxiliary heating mechanism 11 is provided on the outside of one side of the cavity ring 4, and the auxiliary heating mechanism 11 includes a heating rod 1102. The heating rod 1102 is fixed through the inside of the auxiliary roller 1002, and the connecting end of the heating rod 1102 is installed through the outside of one side of the auxiliary roller 1002; the auxiliary heating mechanism 11 also includes a conductive copper ring 1101 and a conductive swivel 1103. A conductive copper ring 1101 is fixed on the outside of the cavity ring 4 near the connecting end of the heating rod 1102, and a conductive swivel 1103 is installed on the outside of the connecting end of the heating rod 1102 for rotation and connection, and one side of the conductive swivel 1103 rotates in contact with the outside of one side of the conductive copper ring 1101.

[0042] Combination Figure 7 and Figure 8As shown, during use, it contacts with the conductive rotating ring 1103 of the external power supply through the conductive copper ring 1101, so that the heating rod 1102 inside the auxiliary roller 1002 generates a certain amount of heat, making the abrasive belt 1004 in contact with the auxiliary roller 1002 also have a certain temperature. At the same time, combined with the heat generated by the abrasive belt 1004 itself during grinding, it can preheat the surface of the pipe to be cut in advance, so that the pipe after preheating can be heated to the ignition point faster during later cutting, obtaining a higher cutting speed and improving the overall cutting efficiency. At the same time, through the through-rotation conduction installation of the conductive rotating ring 1103 and the heating rod 1102, when the auxiliary roller 1002 rotates, it will not affect the conduction and power supply between the conductive rotating ring 1103 and the conductive copper ring 1101, ensuring the overall operation stability and the use effect.

[0043] In some embodiments, the isolation mechanism 12 includes a gear ring 1201, a driving ratchet two 1202, an air collecting chamber 1203, and a piston ring 1204. A gear ring 1201 is fixedly penetrated through the outside of one side of the rotating ring 5. One side of the bottom end of the gear ring 1201 is meshed and connected with a driving ratchet two 1202, and the driving ratchet two 1202 is penetrated and installed on the outside of one side of the rotating shaft 9. The one-way rotation directions of the driving ratchet one 1007 and the driving ratchet two 1202 are set in opposite directions. An air collecting chamber 1203 is arranged inside the limiting ring 7, and a piston ring 1204 is slidably and hermetically installed inside the air collecting chamber 1203; the isolation mechanism 12 further includes a limiting rod 1205, a tension spring 1206, an insulating block 1207, an electromagnet ring one 1208, a magnet ring two 1209, a conduction block one 1210, and a conduction block two 1211. Limiting rods 1205 are fixedly arranged around the side of the piston ring 1204 close to the rotating ring 5 at equal angles, and a tension spring 1206 is sleeved and connected to the outside of the limiting rod 1205. An insulating block 1207 is fixedly arranged on the outside of one side of the bottom end of the rotating ring 5. A magnet ring two 1209 is fixedly arranged on the outside of one side of the piston ring 1204. An electromagnet ring one 1208 is fixedly penetrated through the side of the limiting ring 7 close to the insulating block 1207. The opposite surfaces of the electromagnet ring one 1208 and the magnet ring two 1209 are set to be of the same pole. A conduction block one 1210 and a conduction block two 1211 are symmetrically arranged on both sides of the insulating block 1207; the isolation mechanism 12 further includes a limiting cavity column 1212, a compression spring 1213, an annular airbag 1214, and a conduction pipe 1215. The conduction block one 1210 is conductively fixed to one side of the electromagnet ring one 1208. The conduction block two 1211 is slidably sleeved on the outside of the side close to the cavity ring 4 with a limiting cavity column 1212, and one end of the limiting cavity column 1212 is fixedly arranged on the outside of one side of the cavity ring 4. And a compression spring 1213 is arranged inside the limiting cavity column 1212. An annular airbag 1214 is fixedly arranged on the inner wall of the limiting ring 7, and a conduction pipe 1215 is arranged for conductive connection between the conduction port of the annular airbag 1214 and the air collecting chamber 1203 inside the limiting ring 7.

[0044] Combination Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, when the pipe is derusted and reaches the bottom end of the flame cutting assembly 6 for flame cutting, first, start the brake stepper motor 8 on one side, and drive the rotating shaft 9 to start reverse rotation through the output shaft of the brake stepper motor 8, thereby driving the driving ratchet 2 1202 to rotate. At this time, the driving ratchet 1 1007 no longer rotates, so as to avoid the situation in which the rust removal mechanism 10 on one side continues to run and continuously grinds the outer surface of one side of the pipe during the cutting process, and the excessive grinding and rust removal on the outside of the pipe causes wear that affects subsequent use.

[0045] When the ratchet wheel 1202 is driven to rotate, the gear ring 1201 on one side that is meshed will be driven to rotate synchronously, thereby driving the rotating ring 5 to rotate, so that the rotating ring 5 drives the existing flame cutting assembly 6 to perform rotational cutting on the pipe fitting. When the rotating ring 5 drives the flame cutting assembly 6 to perform rotational cutting, the insulating block 1207 at the bottom of the rotating ring 5 rotates and moves synchronously, so that the insulating block 1207 moves away from between the conductive block 1 1210 and the conductive block 2 1211, so that the compression spring 1213 on one side rebounds. At this time, the conductive block 1210 and the conductive block 2 1211 are in contact and conductive. At the same time, when the device is used, the conductive block 2 1211 needs to be connected to an external power supply to ensure subsequent power supply. The conductive block 1210 and the conductive block 2 1211 are connected. After the contact is made, the electromagnet ring 1208 is energized and starts to repel the magnet ring 2 1209, so that the magnet ring 2 1209 is driven by the repulsive force to move and compress the piston ring 1204, thereby injecting the internal gas of the air collecting chamber 1203 into the annular airbag 1214, causing it to expand and wrap and isolate the side of the pipe, thereby preventing some fine metal dust from splashing out from the side during cutting and diffusing in the workshop air to cause pollution, thereby ensuring the isolation and splash-proof effect of metal dust impurities (at the same time, when manufacturing the device, the annular airbag 1214 can be set on the inner wall of the side of the limit ring 7 away from the flame cutting component 6, and the annular airbag 1214 is made of existing high-temperature resistant and wear-resistant materials, thereby extending the service life of the annular airbag 1214 and ensuring the overall use effect).

[0046] When the cutting is completed, the insulating block 1207 rotates and resets again to between the conductive block 1 1210 and the conductive block 2 1211, so that the conductive block 1210 and the conductive block 2 1211 are in contact and separated. At this time, the electromagnet ring 1208 is powered off, and the tension spring 1206 drives the piston ring 1204 to move back and reset. During the moving back process, the internal gas of the annular airbag 1214 is drawn back into the air collecting chamber 1203, so that the annular airbag 1214 shrinks and contracts, so that the cut pipe will not contact and rub against the surface of the annular airbag 1214 when it is removed, thereby preventing the incision from cutting the surface of the annular airbag 1214, thereby extending the service life of the annular airbag 1214.
