Description

TECHNICAL FIELD

[0001] The application relates to the technical field of laser cutting, and particularly relates to a laser cutting equipment for I-shaped steel pre-burial. BACKGROUND

[0002] The I-shaped steel is long strip steel with an I-shaped cross section, and is often used in building structures. The I-shaped steel must be cut during use. Currently, there are three common cutting methods for the I-shaped steel, namely laser cutting, flame cutting and plasma cutting. The I-shaped steel is mainly divided into ordinary I-shaped steel, light I-shaped steel and wide flange I-shaped steel.

[0003] For example, the application No. 202410807122.5 discloses a laser cutting machine for I-shaped steel processing, and belongs to the technical field of I-shaped steel laser cutting machines. The laser cutting machine for I-shaped steel processing comprises a supporting platform and a conveying frame. The conveying frame is located on one side of the supporting platform. The supporting platform is provided with a lifting assembly on the top. The lifting assembly is provided with a polishing assembly in the middle. The lifting assembly is provided with a cutting assembly on one side. The lifting assembly is rotationally connected with a clamping and overturning assembly. The polishing assembly, the lifting assembly and the clamping and overturning assembly are adopted.

[0004] Taking the above cutting equipment as an example, during the cutting process of the I-shaped steel, the I-shaped steel needs to be positioned with the clamping structure, and then the I-shaped steel is moved transversely to make the I-shaped steel penetrate through two or more clamping structures. The operation is relatively troublesome. Moreover, the I-shaped steel is heavy. During the positioning operation of the I-shaped steel and the clamping structure, the I-shaped steel is prone to collide with the clamping structure. The weak edge wall of the I-shaped steel may be deformed or the clamping structure parts may be damaged, thereby causing economic losses. SUMMARY

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example: Figures 1-13As shown, the present invention provides a technical solution for a laser cutting device for pre-embedding I-beams, including a processing table 1 and a laser cutting machine 18. A support structure is installed on the processing table 1. Two support frames 10 are fixedly connected to the rear side of the top of the processing table 1. Support frames 21 are provided on the top of each of the two support frames 10. A drive assembly is provided between adjacent support frames 10 and support frames 21. A hydraulic cylinder 26 is provided on one side of one of the drive assemblies. A synchronous guide rail structure is provided between the two support frames 21. The synchronous guide rail structure is used to control the position of the laser cutting machine 18. A clamping structure is provided at the bottom of each of the two support frames 21. The clamping structure includes multiple support rollers 51, two housing shells 38, two missing gears 44, one gear 40, one gear 2 41, one drive motor 42, one clamping block 2 48 and a pressure boosting assembly. The two missing gears 44 are respectively located inside the two housing shells 38. Multiple gears 53 mesh with the outer sides of the two missing gears 44. Multiple support rollers 51 are respectively located on both sides of the two missing gears 44.

[0035] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, two support frames 10 are fixedly connected to the rear top of the processing table 1. Each support frame 10 has a support frame 21 on its top. A drive assembly is installed between adjacent support frames 10 and 21. The drive assembly adjusts the position of the support frame 21. A rotating shaft 20 in the drive assembly is rotatably connected inside the support frame 10. Two support frames 519 are fixedly connected between the rotating shaft 20 and the support frame 21. The rotating shaft 20 and support frame 21 move synchronously. A gear 22 fixedly installed on the outside of the rotating shaft 20 meshes with a rack 23 at its bottom. When the rotating shaft 20 rotates, the support frame 21 rotates. Two support frames 312 in the synchronous guide rail structure are fixedly connected between the two support frames 21, causing them to move synchronously. Two protruding grooves 24 on one side of the rack 23 each have a protrusion 25 inside. The protrusion 25 is fixedly connected to the support frame 10, so the rack 23 is limited to its position. The hydraulic cylinder 26 is fixedly installed inside one of the support frames 10. A connecting plate 27 is fixedly connected between the piston end of the hydraulic cylinder 26 and the side wall of the adjacent rack 23. The hydraulic cylinder 26 drives the rack 23 fixed through the connecting plate 27 to move. The movement of the rack 23 drives the meshing gear 22 to rotate. The rotating shaft 20 drives the support frame 11 fixed through the support frame 5 19 to rotate. The support frame 11 drives the other support frame 11 to rotate through the two support frames 3 12. The other support frame 11 drives the other rotating shaft 20 to rotate through its fixed support frame 5 19. The rotating shaft 20 drives the rack 23 to move through the gear 22. The two racks 23 move synchronously in the same direction. By controlling the contraction or extension of the hydraulic cylinder 26, the two support frames 11 rotate counterclockwise or clockwise. The support frames 11 move closer to the top of the processing table 1 and further away from the top of the processing table 1. Furthermore, the brake 21, which is sleeved on the outside of the rotating shaft 20, is fixedly installed inside the support frame 10. After the hydraulic cylinder 26 stops working, the brake 21 works to support the rotating shaft 20, limiting the rotating shaft 20 and the support frame 11.

[0036] Hydraulic cylinders 35 are fixedly inserted into the top of both support frames 21. Two T-shaped rods 36 are fixedly connected to the top of mounting frame 37, whose piston ends are also fixedly connected to the piston ends of hydraulic cylinders 35. The tops of the two T-shaped rods 36 penetrate support frames 21. Under the action of the two T-shaped rods 36 and hydraulic cylinders 35, the mounting frame 37 and support frames 21 can only move relative to each other in the vertical direction. Mounting frame 37 is fixedly connected to drive motor 42, gearbox 2 41, and the upper storage shell 38. Therefore, the upper storage shell 38 moves synchronously with support frames 21, and the lower storage shell 38 is fixedly connected to the processing table 1. Thus, after controlling the retraction of hydraulic cylinder 26, support frames 21 rotate 120° counterclockwise to the rear of the top of the processing table 1, causing the upper storage shell 38 to rotate to the rear of the top of the processing table 1, leaving the top of the lower storage shell 38 unobstructed. Both clamping structures are in the open state; a hydraulic cylinder 14 is fixedly inserted through one of the support frames 3 12 in the synchronous guide rail structure, and a support frame 4 13 is slidably inserted through the other support frame 3 12. A guide rail 15 is fixedly connected between the bottom of the support frame 4 13 and the piston end of the hydraulic cylinder 14. A sliding block 17 is fixedly connected to the piston end of the pneumatic cylinder 2 16 fixedly connected inside the guide rail 15. The sliding block 17 is slidably installed inside the guide rail 15 and fixedly connected to the laser cutting machine 18. Therefore, when the two support frames 3 12 are driven to rotate by the two support frames 2 11, the guide rail 15 rotates synchronously and the laser cutting machine 18 moves. At this time, after the hydraulic cylinder 2 26 retracts, the laser cutting machine 18 moves to the top rear side of the processing table 1. The laser cutting machine 18 is away from the top space of the lower storage shell 38, avoiding damage to the laser cutting machine 18 during the positioning and placement of the I-beam.

[0037] In summary, after the hydraulic cylinder 26 retracts, the two upper storage shells 38, the guide rail 15, and the laser cutter 18 move away from the top of the processing table 1 due to the special structural design of the two drive components and the synchronous guide rail structure. This leaves the top space of the two lower storage shells 38 unobstructed, making it convenient for workers to place the hoisted I-beams into the two lower storage shells 38, avoiding damage to the clamping structure from the I-beams and reducing economic losses.

[0038] The clamping structure consists of multiple support rollers 51, two storage shells 38, two missing gears 44, one gear 40, a second gearbox 41, a drive motor 42, a second clamping block 48, and a pressure boosting component. The two missing gears 44 are respectively located inside the two storage shells 38. Multiple gears 43 mesh with the outer sides of each missing gear 44, and these gears 43 are rotatably connected to the two storage shells 38, supporting the outer sides of the missing gears 44. A brake 53 is fitted onto the outer side of one of the gears 43 located inside the lower storage shell 38. The brake 53 is fixedly installed inside the lower storage shell 38 and, under normal operating conditions, brakes the gear 43, preventing it from moving and thus preventing the missing gear 44 it meshes with from moving. The gear 44 inside the lower storage shell 38 cannot move, and multiple support rollers 51 are respectively set on both sides of the two gears 44. The mounting bracket 4 52 rotatably connected to the support rollers 51 is fixedly connected to the inner wall of the adjacent storage shell 38. Multiple support rollers 51 on the same side are distributed on a circular track. Both sides of the two gears 44 are supported and limited by multiple rotatable support rollers 51. The gear 44 moves according to the preset track under the restriction of multiple gears 53 and multiple support rollers 51. The gear 44 inside the lower storage shell 38 is in a preset state and cannot move. When the worker places the I-beam into the two lower storage shells 38, the two clamping blocks 2 48 fixedly connected inside the two gears 44 support the concave part of the I-beam, so that the I-beam is suspended in the air by the two clamping blocks 2 48.

[0039] After the I-beam is placed, the hydraulic cylinder 26 is extended to reset the two support frames 11 and 12, restoring the upper and lower housing shells 38 to their aligned state. Then, the hydraulic cylinder 35 is activated to push the mounting frame 37 downward, which in turn moves the upper housing shell 38 downward. Finally, the upper housing shell 38 abuts against the lower housing shell 38. Both ends of the upper gear 44 are fixedly connected with locking blocks 50, and both ends of the lower gear 44 have grooves 49. Therefore, the locking blocks 50 will be inserted into the grooves 49 as the upper housing shell 38 moves downward. Under the action of the two grooves 49 and the locking blocks 50, the two gears 44 are joined together. Since the gears 44 move along a preset trajectory under the constraint of multiple gears 43 and multiple support rollers 51, the two gears 44 form a complete large gear.

[0040] After the two storage shells 38 are connected, because the outer shells of the telescopic rod 46 and the hydraulic cylinder 47 in the pressurization assembly are fixedly embedded inside the upper gear 44, and the piston ends of the telescopic rod 46 and the hydraulic cylinder 47 are fixedly connected to the inner wall of the clamping block 45, the hydraulic cylinder 47 is controlled to work to push the clamping block 45 down, the clamping block 45 moves down to abut against the I-beam, and the clamping block 45 and the clamping block 2 48 cooperate to clamp and fix the I-beam.

[0041] Then, control the hydraulic cylinder 14 to adjust the up and down position of the laser cutting machine 18, and control the pneumatic cylinder 16 to adjust the front and back positions of the sliding block 17 and the laser cutting machine 18. At the same time, control the laser cutting machine 18 to cut the I-beam, which can quickly complete the cutting of the I-beam and ensure the flexibility of picking up and putting down the I-beam.

[0042] Example 2:

[0043] When the I-beam is large, the synchronous guide rail structure controls the laser cutting machine 18 to cut the upper part of the I-beam. Then, the hydraulic cylinder 14 drives the laser cutting machine 18 to move upwards away from the I-beam. The output end of the drive motor 42, which moves synchronously with the housing 38, is fixedly connected to the input end of the gearbox 41. The rotating shaft 39, fixedly connected to the output end of the gearbox 41, is rotatably inserted into one side of the upper housing 38. The rotating shaft 39 passes through and is fixedly connected to the gear 40. There is a notch on the upper housing 38 for the gear 40 to rotate, so the gear 40 can rotate. The gear 40 meshes with the upper notched gear 44, so the brake 53 stops working. After the drive motor 42 starts working, the gearbox 41, rotating shaft 39, and gear 40... The large gear 40 rotates, controlling the two drive motors 42 in the two clamping structures to work synchronously. The rotation of the two large gears drives the H-beam to rotate, allowing the H-beam to rotate 90°, 180°, or 270°, completing the flipping of the H-beam and ensuring that the H-beam is completely cut. No operator is required to operate the H-beam during the cutting process, reducing labor costs. Furthermore, the laser cutting machine 18 is positioned between the two clamping structures, and the gap cut by the laser cutting machine 18 on the H-beam is located between the two clamping structures. The H-beam structures on both sides of the gap are clamped and fixed, so the rotation of the H-beam will not change the relative position between the cut gap and the laser cutting machine 18. There is no need to reposition the cutting position, nor will excessive torque be applied to the cutting position of the H-beam, ensuring a neat cut.

[0044] During the above process, before the drive motor 42 stops working, the I-beam is rotated by an integer multiple of 180°. After the drive motor 42 stops working, the brake 53 is activated, so that the bottom missing gear 44 is in a preset state and will not be displaced under the influence of the movement of the I-beam, ensuring that the two missing gears 44 can smoothly form a large gear.

[0045] Example 3, as Figure 1 , Figure 8 and Figure 9 As shown: The support structure includes a mounting bracket 2 and a pneumatic cylinder 3 located at the bottom of the processing table 1. The pneumatic cylinder 3 is fixedly installed at the bottom of the processing table 1, and its piston end is fixedly connected to the inner wall of the mounting bracket 2. Multiple mounting brackets 5 are located at the top of the processing table 1. Three mounting rods 4 are fixedly connected between the bottom of the mounting brackets 5 and the mounting bracket 2. The bottom ends of the mounting rods 4 penetrate the processing table 1 to limit the movement of the mounting brackets 2, allowing the mounting brackets 2 to move up and down. Support rods 6 are rotatably mounted on each of the multiple mounting brackets 5. Two rolling elements 7 are fixedly sleeved on the outside of each support rod 6. When the I-beam is supported by the two clamping structures, the pneumatic cylinder 3 is controlled. The working mechanism moves the mounting bracket 12 upwards, and multiple mounting brackets 25 upwards, causing multiple rolling elements 7 to abut the bottom of the I-beam, thus sharing the pressure on the clamping structure. After the I-beam is cut, the telescopic rod 46 at the top of the cut I-beam drives the clamping block 1 45 upwards, causing the clamping block 1 45 to disengage from the cut I-beam. At this time, the cut I-beam is supported by multiple rolling elements 7, which can push the cut I-beam away from the bottom of the laser cutting machine 18. Only a trolley needs to be set in front of the movement of the cut I-beam. When the cut I-beam leaves the top of the processing table 1, it can fall onto the trolley, making it convenient to adjust the position of the cut I-beam. Similarly, controlling the telescopic rod 46 at the top of the I-beam to be cut drives the clamping block 45 to move upward. The I-beam to be cut is supported by multiple rolling parts 7 and can be easily pushed. The position of the I-beam can be adjusted by passing through another clamping structure, thus completing the re-fixing of the I-beam. This allows the position to be cut to move easily to the bottom of the laser cutting machine 18. The position of the I-beam can be adjusted without the need for hoisting equipment, reducing the cost of I-beam cutting and processing.

[0046] In Example 2, when the I-beam needs to be flipped, the pneumatic cylinder 3 is first controlled to push the mounting bracket 2 downward, and multiple rolling parts 7 are disengaged from the flipping trajectory of the I-beam.

[0047] Example 4: A rack 28 is fixedly connected to the side of rack 23 near brake 21. A gear 29 is fixedly installed on the outer side of the input end of gearbox 30, which is fixedly connected to the front of support frame 10. Gear 29 meshes with rack 28. A gear 31 is fixedly connected to the output end of gearbox 30, which meshes with rack 32. An L-shaped plate 33 is fixedly connected to one end of rack 32 and is fixedly connected to support frame 6 34, which passes through support frame 10. Support frame 6 34 supports and limits L-shaped plate 33. When hydraulic cylinder 2 26 retracts... When the rack 23 moves and the support frame 11 flips away from the top of the processing table 1, the L-shaped plate 33 moves towards the support frame 10 under the action of the rack 23, rack 28, gear 29, gear 31, and rack 32. The L-shaped plate 33 will not affect the operation and construction of the I-beam. When the support frame 11 returns to a state parallel to the top of the processing table 1, the L-shaped plate 33 moves away from the support frame 10. The L-shaped plate 33 supports the bottom of the support frame 11, increases the working stability of the support frame 11, and reduces the possibility of deformation of the support frame 11.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
