Description

Technical Field

[0001] The present invention relates to the field of laser cutting, and particularly to a cutting device for railway maintenance machinery processing. Background Art

[0002] When processing railway maintenance machinery, a laser cutting machine is required. The existing patent (Publication No.: CN116571901A) proposes a laser cutting machine, which includes two frames, a working platform, a cutting platform, a gantry, a laser cutting head, and a dust removal device. The working platform includes two groups of side beams respectively arranged on both sides thereof, a plurality of columns, and a cross beam connected between the two columns. Each group of side beams includes an upper side beam and a lower side beam, and the columns are connected between the upper side beam and the lower side beam. When processing railway maintenance machinery, this device "places the workpiece to be cut on the support surface formed by a plurality of rack plates, and moves the gantry along the frame to drive the laser cutting head to move to the corresponding position". During the laser cutting process, the metal vapor generated may remain on the rack plates to form waste residues. Excessive accumulation of the waste residues may cause the upper surface of the rack plates to be uneven, affecting the subsequent laser cutting operation during railway maintenance machinery processing. Summary of the Invention

[0003] In view of the above deficiencies of the prior art, the present invention provides a cutting device for railway maintenance machinery processing, which cools the waste residue collection net through the coolant flowing inside the cooling net, and cooperates with the negative pressure generated inside the main support platform to assist the high-temperature metal vapor generated during the laser cutting process to descend, so that the high-temperature metal vapor passing through the waste residue collection net is cooled and sublimated on the waste residue collection net, facilitating the subsequent centralized recovery of the waste residues. At the same time, it also prevents excessive accumulation of waste residues on the laser cutting sword grid, facilitating the subsequent cleaning of the laser cutting sword grid, and avoiding the influence of excessive accumulation of waste residues on the subsequent laser cutting operation.

[0008] 1. In the present invention, the negative pressure generated inside the main support platform assists the high-temperature metal vapor generated during the laser cutting process to descend, making it less likely for the high-temperature metal vapor generated during the metal cutting process to accumulate under the metal plate and cause slag hanging, thereby improving the cutting effect.

[0009] 2. In the present invention, the coolant flowing inside the cooling net cools the waste residue collection net, so that the high-temperature metal vapor passing through the waste residue collection net cools and sublimes on the waste residue collection net, facilitating the subsequent centralized recovery of the waste residue. At the same time, it also prevents excessive accumulation of waste residue on the laser cutting sword grid, facilitating the subsequent cleaning of the laser cutting sword grid, with accurate cutting and preventing defects, slag hanging, or crack phenomena on the cutting section.

[0010] 3. During the forward movement of the laser cutting mechanism of the present invention, the waste residue cleaning knife inside the laser cutting mechanism continuously swings left and right. Through the left and right swinging of the waste residue cleaning knife, the waste residue cleaning knife can clean the same position of the laser cutting sword grid multiple times during the forward movement of the laser cutting mechanism, thereby improving the cleaning effect of this device.

[0011] 4. The cleaning mask block of the present invention is designed in an inverted U shape itself, so that the cleaning mask block always masks the outside of the waste residue cleaning knife during the cleaning process, thereby avoiding secondary pollution caused by the overflow of waste residue during the cleaning process. At the same time, the cleaned waste residue will also be recycled through the waste residue recovery hole, making the cleaning process more efficient and tidy. Brief Description of the Drawings

Detailed implementation manners

[0026] The present invention will be further described in detail below with reference to the drawings and embodiments:

[0027] Embodiment 1:

[0028] A railway maintenance machinery processing and cutting device includes a main support platform 1.

On the upper part of the main support platform 1, there are a waste residue cleaning mechanism 3 and a laser cutting mechanism 4. The waste residue cleaning mechanism 3 is located on the side of the laser cutting mechanism 4. The laser cutting mechanism 4 performs laser cutting operations on the workpiece to be processed. After the laser cutting mechanism 4 finishes processing, the waste residue cleaning mechanism 3 cleans and recovers the metal residues remaining on the main support platform 1.

[0029] Embodiment 2:

[0030] The waste residue auxiliary recovery mechanism 2 of the present invention includes a lower waste gas recovery pipe 12, a lower recovery cover 13, a cooling net limiting plate 15, a coolant bearing pipe 17, fastening screws 19, a cooling net 23, and a waste residue collection net 24. Both sides of the main support platform 1 have cooling net connection grooves 21, which are adapted to the cooling net 23. The cooling net 23 is connected to the cooling net connection grooves 21 and is inserted into the interior of the cooling net connection grooves 21. The side surface of the cooling net 23 has a cooling pipe connection port 16, and the interior of the cooling net 23 is hollowed out. The cooling pipe connection port 16 is communicated with the interior of the cooling net 23. The cooling net limiting plate 15 is adapted to the cooling pipe connection port 16, and the cooling net limiting plate 15 is connected to the cooling pipe connection port 16 and sleeved on the outer side of the cooling pipe connection port 16.

The lower waste gas recovery pipe 12 is inserted and fixed into the interior of the lower recovery pipe connection port 11, and the other end of the lower waste gas recovery pipe 12 is connected to an air extractor.

[0031] Embodiment 3:

[0032] The waste residue cleaning mechanism 3 of the present invention includes a waste residue cleaning knife 25, a cleaning mask block 26, a cleaning drive motor 37, a traveling drive gear 39, a main support wheel 48, a swing drive gear 49, and a secondary support wheel 53. Above the upper part of the main support table 1, there is a cleaning mask block 26. At the top of the cleaning mask block 26, there is a waste residue recovery pipe 28. The end of the waste residue recovery pipe 28 is connected to an air extractor. Inside the cleaning mask block 26, there are waste residue recovery holes 27. On both sides of the cleaning mask block 26, there are gear mounting plates 18. Among them, at the bottom of the gear mounting plate 18 on the side away from the lower recovery cover 13, there is a limit wheel mounting platform 62. On the outside of the gear mounting plate 18, there is a cleaning motor slot 36. The cleaning drive motor 37 is inserted and fixed inside the cleaning motor slot 36. The transmission shaft of the cleaning drive motor 37 passes through the gear mounting plate 18 and is fixedly connected to the swing drive gear 49. On one side of the gear mounting plate 18, there is a traveling gear mounting shaft 46. The traveling gear mounting shaft 46 is rotatably connected to the traveling drive gear 39. The bottom of the traveling drive gear 39 meshes with the traveling rack 38. The side of the traveling drive gear 39 meshes with the swing drive gear 49. On the side of the traveling gear mounting shaft 46, there is a main support wheel connecting shaft 47. The main support wheel connecting shaft 47 is rotatably connected to the main support wheel 48. The main support wheel 48 presses against the upper surface of the main support table 1. On the other side of the gear mounting plate 18, there is a secondary support wheel mounting platform 54. On the side of the secondary support wheel mounting platform 54, there is a secondary support wheel connecting shaft 52. The secondary support wheel connecting shaft 52 is rotatably connected to the secondary support wheel 53. The secondary support wheel 53 presses against the upper surface of the main support table 1. Inside the limit wheel mounting platform 62, there is a limit wheel mounting groove 63. The limit wheel mounting groove 63 is rotatably connected to the limit wheel 64. The limit wheel 64 presses against the lower side of the traveling rack 38 at the corresponding position. Inside the cleaning mask block 26, there is a waste residue cleaning knife 25. At the top of the main support table 1, there is a laser cutting sword grid 14. Between adjacent laser cutting sword grids 14, there are exhaust gas passing holes 43. The laser cutting sword grid 14 is adapted to the waste residue cleaning knife 25. The laser cutting sword grid 14 is connected to the waste residue cleaning knife 25. The waste residue cleaning knife 25 slides outside the laser cutting sword grid 14. On both sides of the waste residue cleaning knife 25, there are swing column connection blocks 44. Inside the swing column connection blocks 44, there are swing column connection grooves 45. On the side of the swing drive gear 49, there is a swing drive column 51. The swing drive column 51 is adapted to the swing column connection groove 45. The swing drive column 51 is connected to the swing column connection groove 45. The swing drive column 51 slides inside the swing column connection groove 45.

[0033] Further, the high-temperature metal vapor generated during the laser cutting process is blown into the interior of the main support platform 1 through the waste gas through-hole 43. The air extractor connected to the lower waste gas recovery pipe 12 is started, creating a negative pressure inside the main support platform 1. This causes the high-temperature metal vapor blown into the interior of the main support platform 1 to enter the interior of the lower waste gas recovery pipe 12 through the waste residue collection net 24 and the cooling net 23. Synchronously, the coolant is injected into the interior of the cooling net 23 from the coolant carrying pipe 17 on one side and flows out from the coolant carrying pipe 17 on the other side, enabling the cooling net 23 to cool the waste residue collection net 24. As a result, when the high-temperature metal vapor passes through the waste residue collection net 24, it directly sublimates on the surface of the waste residue collection net 24, and the remaining waste gas is subsequently recovered by the lower waste gas recovery pipe 12.

[0034] Further, after the laser cutting is completed, the cleaning drive motor 37 is started. The cleaning drive motor 37 drives the swing drive gear 49 to rotate, and the swing drive gear 49 drives the travel drive gear 39 to rotate, causing the waste residue cleaning mechanism 3 to linearly travel on the travel rack 38. During the travel, the swing drive post 51 of the swing drive gear 49 slides inside the swing post connection groove 45 of the waste residue cleaning blade 25. As the laser cutting mechanism 4 advances, the waste residue cleaning blade 25 continuously slides left and right at high speed on the surface of the laser cutting sword grid 14, thus completing the cleaning of the waste residue on the surface of the laser cutting sword grid 14. At the same time, the air extractor connected to the position adjustment drive gear 66 is started, creating a negative pressure inside the cleaning mask block 26, and the waste residue is recovered through the waste residue recovery hole 27.

[0035] It should be noted that the negative pressure generated inside the main support platform 1 assists the downward movement of the high-temperature metal vapor generated during the laser cutting process, making it less likely for the high-temperature metal vapor generated during the metal cutting process to accumulate under the metal plate and cause slag hanging, thereby improving the cutting effect.

[0036] It should also be noted that the coolant flowing inside the cooling net 23 cools the waste residue collection net 24, causing the high-temperature metal vapor passing through the waste residue collection net 24 to cool and sublime on the waste residue collection net 24, facilitating the subsequent centralized recovery of the waste residue. At the same time, it also prevents excessive accumulation of waste residue on the laser cutting sword grid 14, facilitating the subsequent cleaning of the laser cutting sword grid 14. The cutting section is neat and has good flatness, preventing concavities and convexities below the cutting surface.

[0037] It should also be noted that during the advancement of the laser cutting mechanism 4, the waste residue cleaning blade 25 inside the laser cutting mechanism 4 continuously swings left and right. Through the left and right swinging of the waste residue cleaning blade 25, the waste residue cleaning blade 25 can clean the same position of the laser cutting sword grid 14 multiple times during the advancement of the laser cutting mechanism 4, thereby improving the cleaning effect of this device.

[0038] It should also be noted that the cleaning mask block 26 itself is designed in an inverted U shape, so that the cleaning mask block 26 always masks the outside of the waste residue cleaning knife 25 during the cleaning process, thereby avoiding secondary pollution caused by the overflow of waste residue during the cleaning process. At the same time, the cleaned waste residue will also be recycled through the waste residue recovery hole 27, making the cleaning process more efficient and tidy.

The cutting mechanism positioning slideway 55 is connected to the lower cutting mechanism bearing platform 57, and the lower cutting mechanism bearing platform 57 slides outside the cutting mechanism positioning slideway 55. Inside the cutting mechanism positioning slideway 55, there is an adjusting rack 56. On one side of the lower cutting mechanism bearing platform 57, there is an adjusting motor mounting platform 59. The adjusting motor 61 is inserted and fixed inside the adjusting motor mounting platform 59. The transmission shaft of the adjusting motor 61 passes through the lower cutting mechanism bearing platform 57 and is fixedly connected to the adjusting driving gear 66. The adjusting driving gear 66 meshes with the adjusting rack 56. The side of the lower cutting mechanism bearing platform 57 is fixedly connected to a lifting hydraulic cylinder 58.
