Description

Technical Field

[0001] The utility model belongs to the technical field of fish belly beam production, and particularly relates to laser hole cutting and flange cutting equipment based on fish belly beam production. Background Art

[0002] The fish belly beam has high bending strength, with a large middle cross-section that gradually decreases towards both ends of the beam. It can be used as a lower side beam in structures such as locomotives and carriages.

[0003] Fishbelly beams are typically made from I-beams. The webs are cut at both ends of the material to create a fishbelly shape, and then the webs on either side of the cut are pressed together. Finally, the pressed seam is welded. After the fishbelly cutting, pressing, and welding, the material also needs to have its flange cut and holes drilled in the web. Existing cutting equipment often uses laser cutting machines. Because the cutting head has a fixed orientation, the material must be flipped back and forth during cutting to adjust the flange and web position to align with the cutting head. However, the material's bulkiness makes manual flipping difficult, and during the cutting process, the material can easily become loosely positioned, leading to flange deformation after cutting.

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0026] like Figure 1-Figure 5 As shown, a laser hole cutting and flange cutting device for fish belly beam production includes a cutting base 1, a clamping mechanism, a lifting guide assembly, a turning mechanism, a material transmission mechanism, a belt conveyor 2, a cutting operation table, a laser cutting mechanism, and a smoke purification hood 3. Two cutting bases 1 are provided, and the two cutting bases 1 are arranged opposite each other. A plurality of clamping mechanisms are sequentially arranged on the cutting base 1 along the material transmission direction, and the clamping mechanisms are equipped with lifting guide assemblies. The turning mechanism is arranged between the two cutting bases 1, and the material transmission mechanism is arranged on the turning mechanism. The belt conveyor 2 is arranged on the cutting base 1 below the clamping mechanism. The cutting operation table and laser cutting mechanism are arranged on one side of the cutting base 1. The smoke purification hood 3 covers the laser cutting mechanism and the cutting base 1.

[0027] The raw materials are transported by the material conveying mechanism, and the lifting and guiding mechanism is used to convey and guide the raw materials during the material conveying process. After the raw materials are transported to the processing station, the raw materials are first turned 90° by the flipping mechanism and then placed on the clamping mechanism, so that the raw materials are in a side-standing state, that is, one side flange of the raw materials is flatly supported on the clamping mechanism, and then the material conveying mechanism positions the raw materials, and at the same time the clamping mechanism clamps and fixes the raw materials. After the raw materials are fixed, the laser cutting mechanism starts to cut the flange at the top of the raw materials, and an exhaust fan can be installed on the smoke purification hood 3, and then the exhaust fan is used to extract the smoke generated during cutting; after the raw material flange is cut, the material conveying mechanism and the clamping mechanism release the raw materials, and the raw materials are rotated 90° by the flipping mechanism and placed on the clamping mechanism, and then the material conveying mechanism and the clamping mechanism fix the raw materials again at the same time, and then the laser cutting mechanism starts to cut holes in the web.

[0028] like Figure 2As shown, the clamping mechanism includes a clamping platform 4, a clamping oil cylinder 5, a slide 6, a slide 7, a clamping steel pipe 8, a main plate 9, and a sub-plate 10. The lifting guide assembly includes a worm gear lift 11 and a guide roller 12. The clamping platform 4 is fixed on the cutting base 1, and the slide 6 is fixed at both ends of the top of the clamping platform 4. Slides 7 are slidingly provided on the slide 6. The two slides 7 are arranged opposite to each other. A clamping drive oil cylinder corresponding to the two slides 7 is installed on the clamping platform 4. The output end of the clamping oil cylinder 5 is fixed to the bottom of the corresponding slide 7. A clamping steel pipe 8 is provided on the opposite side of the two slides 7. One end of the clamping steel pipe 8 is fixed to the slide 7. A flat main plate 9 is fixed on the top of the other end of the clamping steel pipe 8. Sub-plates 10 parallel to the main plate 9 are fixed on both sides of the other end of the clamping steel pipe 8. The raw material is placed on the clamping platform 4. Behind the clamping platform 4, two clamping cylinders 5 drive two slides 7 to slide toward or away from each other on the slideway 6, so that the two clamping steel pipes 8 move toward or away from each other, and then the two clamping steel pipes 8 cooperate to clamp or release the raw material. After clamping the raw material, the main plate 9 and the auxiliary plate 10 are located below the flange at the top of the raw material and block the flange at the bottom of the raw material. In this way, during the flange cutting and hole making process, the laser passing through the flange at the top of the raw material will act on the main plate 9 and the auxiliary plate 10, thereby preventing the laser from accidentally damaging the flange at the bottom of the raw material. Two worm gear elevators 11 are installed on one side of the clamping platform 4. The two ends of the guide roller 12 are respectively fixed to the output ends of the two worm gear elevators 11. The guide roller 12 is driven up by the worm gear elevator 11, so that the guide roller 12 supports the raw material upward. In this way, the guide roller 12 can guide the raw material during the transmission process.

[0029] like Figure 1 As shown, a conveying trough is provided on the top of the cutting base 1 along the material transmission direction, the clamping platform 4 is erected above the conveying trough, and the belt conveyor 2 is installed in the conveying trough. The waste generated by cutting can fall directly onto the belt conveyor 2, and then the waste is discharged through the belt conveyor 2.

[0030] like Figure 1 、 Figure 3As shown, the flipping mechanism includes a flip chassis 13 and a lifting and flipping assembly. The flip chassis 13 is arranged between the two cutting bases 1, the lifting and flipping assemblies are arranged at both ends of the flip chassis 13, and the material transmission mechanism is arranged on the flip chassis 13 between the two lifting and flipping assemblies. The jacking and flipping assembly includes a worm gear elevator 11, a flip seat 14, a support roller 15, a flip ring 16, a flip motor 27, and a chain 29. The worm gear elevator 11 is installed on the flip base 13, and the flip seat 14 is fixed to the output end of the worm gear elevator 11. The flip seat 14 is a groove structure. Support rollers 17 are installed at both ends of the flip seat 14. The flip ring 16 is rollingly supported on the two support rollers 15. The flip motor 32 is installed on the side wall of the flip seat 14. A chain 33 is sleeved on the outer peripheral wall of the flip ring 16. A gear meshing with the chain 33 is installed at the output end of the flip motor 32. The flip ring 16 is provided with a bayonet 17 that matches the appearance of the raw material. A guide telescopic rod 34 is installed on the flip base 13 below the flip seat 14, and the bottom of the flip seat 14 is fixedly connected to the top of the guide telescopic rod 34.

[0031] During the process of the material conveying mechanism conveying the raw materials, the raw materials pass through the bayonet 17 and are then stuck on the flipping ring 16. When the raw materials need to be flipped, the worm gear elevator 11 drives the flipping seat 14 to rise, and the guide telescopic rod 34 is used to guide the movement of the flipping seat 14, so that the raw materials are located above the clamping mechanism and the material conveying mechanism, so that there is enough space to flip the raw materials. Then, under the rolling support of the support roller 15, the flipping motor 32 drives the flipping ring 16 to rotate around its own central axis through the gear and chain 33, thereby flipping the raw materials. After the flipping is completed, the worm gear elevator 11 drives the flipping seat 14 to descend, and then places the raw materials on the clamping mechanism and the material conveying mechanism.

[0032] like Figure 4As shown, the material conveying mechanism includes a conveyor frame 18, a conveyor roller conveyor, a conveyor motor 19, and an adjustable tensioning assembly. The conveyor frame 18 is fixed to the tilting chassis 13. The conveyor roller conveyor includes multiple conveyor rollers 20 and multiple driven rollers 21. These multiple conveyor rollers 20 and multiple driven rollers 21 are alternately mounted on the conveyor frame 18 along the material conveying direction. The conveyor rollers 20 are driven by the conveyor motor 19 mounted on the conveyor frame 18. Driven by the conveyor motor 19, the alternating arrangement of the conveyor rollers 20 and driven rollers 21 achieves alternating master-slave relay transmission of the raw materials, ensuring smoother and more reliable material transport. The adjusting tightening mechanism is arranged between the transmission roller 20 and the driven roller 21. The adjusting tightening assembly includes a tightening cylinder 22, a tightening pressure head 23, and a positioning pad 24. The tightening cylinder 22 and the tightening pressure head 23 are installed on one side of the top of the conveyor frame, and the positioning pad 24 is fixed on the other side of the top of the conveyor frame and opposite to the tightening pressure head 23. The end of the tightening pressure head 23 opposite to the positioning pad 24 is fixed to the output end of the tightening cylinder 22. During the transmission process, the raw material is located between the tightening pressure head 23 and the positioning pad 24. The tightening cylinder 22 drives the tightening pressure head 23 to push against the raw material until the tightening pressure head 23 pushes the raw material against the positioning pad 24, and then positions the raw material between the tightening pressure head 23 and the positioning pad 24.

[0033] As shown in Figures 1 and 5, the laser cutting mechanism includes a cutting gantry 25, an x-axis linear module 26, a y-axis linear module 27, a z-axis linear module 28, and a laser cutting machine 29. The cutting gantry 25 is fixed to one side of the cutting base 1, the x-axis linear module 26 is mounted on the cutting gantry 25 along the material transmission direction, the y-axis linear module 27 is mounted on the x-axis linear module 26, the z-axis linear module 28 is mounted on the y-axis linear module 27, and the laser cutting machine 29 is mounted on the z-axis linear module 28. When the raw material is fixed, the laser cutting machine 29 can be moved forward and backward, left and right, and up and down under the drive of the x-axis linear module 26, the y-axis linear module 27, and the z-axis linear module 28, thereby adjusting the position of the laser cutting machine 29 so that the laser cutting machine 29 can cut different positions of the raw material.

[0034] like Figure 1 As shown, the cutting console includes an air-conditioned constant-temperature room 30, a voltage-regulated power supply 31, a water chiller, and a laser. The laser and water chiller are installed in the air-conditioned constant-temperature room 30. The laser is electrically connected to the voltage-regulated power supply 31, and the laser cutting machine 29 and the water chiller are both connected to the laser. The laser light generated by the laser is used for cutting operations, while the water chiller cools the laser to maintain normal operation.

[0035] The working principle of this utility model is as follows:

[0036] When the raw materials are transported, the raw materials are placed flat on the transport roller, that is, the raw material flange is supported on the transport roller 20 and the driven roller 21, and at the same time, the worm gear elevator 11 in the jacking guide assembly drives the guide roller 12 to support the raw materials upward, and then the transmission motor 19 drives the transmission roller 20 to transport the raw materials, so that the raw materials pass through the bayonet 17 on the flip ring 16. When the raw materials are transported in place, the worm gear elevator 11 in the jacking flip assembly drives the flip seat 14 to rise, and lifts the raw materials above the clamping mechanism and the material transmission mechanism. Then, under the rolling support of the support roller 15, the flip motor 32 drives the flip ring 16 to rotate around its own central axis through the gear and chain 33, flipping the raw materials 90°, and then the worm gear elevator 11 descends and places the raw materials on the transport roller and the clamping table 4, and then the tightening cylinder 22 drives the tightening pressure head 23 The raw material is pushed forward and positioned between the clamping pressure head 23 and the positioning pad 24. At the same time, the two clamping cylinders 5 drive the two slides 7 to slide toward each other, and the raw material is clamped by the cooperation of the two clamping steel pipes 8. After the raw material is clamped, the main plate 9 and the sub-plate 10 are located below the flange at the top of the raw material and cover the flange at the bottom of the raw material. After the raw material is fixed, the laser cutting mechanism starts to work to cut the raw material flange; after the raw material flange cutting is completed, the clamping mechanism and the adjusting clamping assembly release the raw material, and then the flipping mechanism repeats the above flipping action to rotate the raw material 90°. After the raw material rotates, the clamping mechanism and the adjusting clamping assembly fix the raw material again, and then the cutting mechanism works to cut holes in the raw material web. After cutting is completed, the flipping mechanism places the raw material on the transmission roller and guide roller 12, and then the transmission motor 19 works to transmit the raw material to the subsequent processing steps. During the cutting process, the raw material is positioned and clamped by the clamping mechanism and the adjustable tightening assembly to keep the raw material stable, thereby preventing the raw material flange from deforming after cutting. The waste generated after cutting can automatically fall onto the belt conveyor 2, and then the waste can be discharged in time through the belt conveyor 2.
