Description

Technical Field

[0001] The invention relates to the field of steel structure cutting, in particular to a cutting device for steel structures. Background Art

[0002] Steel structure cutting is a very important link in steel structure processing. It directly affects the manufacturing quality, production efficiency and economy of the steel structure. At present, there are many kinds of steel structure cutting technologies, including traditional flame cutting, plasma cutting, water cutting, CNC cutting, etc., as well as laser cutting technology which has gradually become the mainstream in recent years.

[0003] When using laser cutting technology to cut steel plates, you first need to place the steel plates neatly in designated positions, and then use clamping equipment to fix the placed steel plates in position. Laser cutting technology is based on the high energy density characteristics of lasers. The function of the laser generator is to generate a high-power, high-quality laser beam, focus the laser beam on the surface of the material, and make the material melt, vaporize or burn quickly, thereby achieving the purpose of cutting. After the cutting is completed, the staff needs to release the clamping equipment and then take out the cut steel plate.

[0004] In the process of cutting large quantities of steel plates of the same type, each steel plate needs to be adjusted in position, clamped, and the like. The workers repeat the above steps, which takes up a lot of time in the cutting process and causes slow cutting speed. At the same time, manual operation may easily cause injuries when touching the steel plates. In addition, during the cutting process, when a high-power laser beam irradiates the material, the material will be melted and vaporized, thereby generating dust and smoke. The dust and smoke may contain tiny particles of the material itself and coatings or pollution on its surface, or when cutting certain coated metals, toxic smoke may be released. The smoke may cause harm to the health of the operator. Therefore, a cutting device for steel structure is proposed. Summary of the invention

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a cutting device for steel structures.

[0042] In a typical implementation of the present application, Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, a cutting device for steel structure, comprising:

[0043] A cutting platform 1, a device base 2 is provided below the cutting platform 1, a stepping motor 4 is provided between the cutting platform 1 and the device base 2, four cutting placement slots 3 are provided on the cutting platform 1, and a steel plate body 8 is placed on the cutting placement slots 3;

[0044] The material conveying component 5 is arranged on the side of the cutting platform 1 and is used to convey the steel plate body 8. The material conveying component 5 includes a conveyor belt 6 and an output belt 7 arranged on the equipment base 2. The conveyor belt 6 and the output belt 7 are arranged in a vertical position. Four cutting placement slots 3 are provided;

[0045] A position adjustment component 9 is arranged on one side of the cutting platform 1 to push and adjust the position of the conveyed steel plate body 8. The position adjustment component 9 includes four racks 10 fixedly installed on the outside of the cutting platform 1. A rotating shaft 11 is rotatably installed on the top of the equipment base 2. A gear 12 is fixedly sleeved on the rotating shaft 11. The gear 12 is meshed with a corresponding rack 10. Four support rods 13 are fixedly installed on the top of the rotating shaft 11. Arc-shaped pushing blocks 14 are fixedly installed at the ends of the four support rods 13. An annular sleeve 15 is fixedly installed on the top of the equipment base 2. The rotating shaft 11 is located in the annular sleeve 15. Four fixed arc-shaped spring blocks 16 are fixedly installed on the inner wall of the annular sleeve 15. Four rotating arc-shaped spring blocks 17 are fixedly installed on the outside of the rotating shaft 11. The four fixed arc-shaped spring blocks 16 and the four rotating arc-shaped spring blocks 17 are staggered.

[0046] When cutting large quantities of steel plate bodies 8 of the same specification, the material is transported through the material conveying component 5. The conveyor belt 6 on the material conveying component 5 feeds the steel plate body 8. The staff stands between the conveyor belt 6 and the output belt 7, places the steel plate body 8 transported in on the cutting placement groove 3 in the front, starts the stepper motor 4 to drive the cutting platform 1 to rotate, and each rotation is set to rotate ninety degrees. During the rotation, the rack 10 on the side of the cutting platform 1 will contact and engage with the gear 12, thereby driving the gear 12 to rotate, and the rotating shaft 11 will rotate synchronously, driving the upper arc-shaped push block 14 to rotate. The arc-shaped push block 14 can rotate to the cutting placement groove 3, and push the steel plate body 8 placed on the outside to the internal position, so as to avoid the problem that the placement position of the steel plate body 8 is inaccurate during the placement of the steel plate body 8 by the staff, thereby affecting the accuracy of the subsequent cutting.

[0047] Furthermore, in the above scheme, the four fixed arc-shaped spring blocks 16 arranged inside the annular sleeve 15 are alternately arranged with the four rotating arc-shaped spring blocks 17. After rotating one circle of the four, the rotating shaft 11 is prevented from rotating due to the rotational inertia of the gear 12 under the blocking action of the rotating arc-shaped spring blocks 17 and the fixed arc-shaped spring blocks 16. The rotating shaft 11 does not rotate without the action of external force, which facilitates the next arc-shaped pushing block 14 to push the steel plate body 8 in the next cutting placement groove 3.

[0048] As a preferred implementation in this embodiment, Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a clamping and positioning component 18 is arranged on the cutting platform 1, and is used for clamping the conveyed steel plate body 8.

An arc-shaped fixed block 34 is installed above the equipment base 2, and the arc-shaped fixed block 34 is adapted to the arc-shaped frame 33. An arc-shaped guide port 35 is provided at the end of the arc-shaped fixed block 34. A rotating roller 36 is rotatably mounted on the arc-shaped frame 33, and the rotating roller 36 contacts the side of the arc-shaped fixed block 34. A threaded groove 25 is provided at the end of the L-shaped moving block 23, and a threaded column 26 is threadedly mounted on the threaded groove 25. A rotating disk 27 is fixedly sleeved on the threaded column 26, and a convex rotating column 29 is fixedly mounted on the end of the threaded column 26. A convex rotating groove 28 is provided on the side of the clamping plate 24, and the convex rotating column 29 is rotatably mounted in the convex rotating groove 28.

[0049] The cutting platform 1 rotates again. During the rotation, the rotating roller 36 on the arc frame 33 will contact the arc guide port 35, and then contact the arc fixed block 34. The contact forms extrusion, which will drive the extrusion push rod 31 to move. After the extrusion push rod 31 moves, it will drive the two linkage rods 32 to move, thereby driving the two guide blocks 22 to approach each other and compress the reset spring 30. After the two guide blocks 22 approach each other, they will drive the two L-shaped moving blocks 23 to move, thereby driving the two clamping plates 24 to automatically clamp the placed steel plate body 8, thereby realizing automatic clamping and positioning of the steel plate body 8 during rotation, without the need for manual clamping operations by the staff, thereby reducing a lot of time occupied by clamping.

[0050] Furthermore, in the above scheme, a plurality of rotating rollers 36 are provided to reduce the contact friction between the arc frame 33 and the arc fixed block 34. The threaded groove 25 and the threaded column 26 are provided. After the threaded column 26 rotates in the threaded groove 25, the initial position of the clamping plate 24 can be adjusted, so that steel plate bodies 8 of different widths can be clamped. The clamping range is wide. The rotating disk 27 is provided to facilitate the rotation of the threaded column 26. The convex rotating column 29 is provided to rotate in the convex rotating groove 28. When the threaded column 26 rotates, the clamping plate 24 will not rotate.

[0051] As a preferred implementation in this embodiment, Figure 1 , Figure 5 and Fig.12 As shown, the cutting component 54 is provided on the equipment base 2 and is used for cutting the clamped steel plate body 8. The cutting component 54 includes a bracket 55 fixedly installed on the equipment base 2, a telescopic cylinder 56 is fixedly installed on the bracket 55, an output end of the telescopic cylinder 56 is connected to a moving frame 57, a driving motor 58 is fixedly installed on one side of the moving frame 57, an output end of the driving motor 58 is connected to a rotating screw 59, a screw moving block 60 is threadedly sleeved on the rotating screw 59, and a cutting head 61 is connected to the bottom of the screw moving block 60.

[0052] During the extrusion movement, the arc frame 33 will drive the first trigger block 52 to move and contact the second trigger block 53. At this time, the drive motor 58 and the exhaust fan 46 are both powered on. After the drive motor 58 is running, it can drive the cutting head 61 to move back and forth. The cutting head 61 is connected to the external laser cutting equipment, and the emitted laser beam is focused on the surface of the steel plate body 8 to realize the cutting operation of the steel plate body 8.

[0053] As a preferred implementation in this embodiment, Figure 3 , Fig. 9 , Fig.10 and Fig.11As shown, an exhaust dust removal component 37 is arranged on the cutting platform 1 for removing dust during the cutting process. The exhaust dust removal component 37 includes a collecting groove 38 opened on the side of the cutting platform 1. The bottom and side of the cutting placement groove 3 are respectively provided with a lower collecting hole 39 and a side collecting hole 40. The lower collecting hole 39 and the side collecting hole 40 are both connected to the collecting groove 38. An annular connecting cavity 41 is opened on the cutting platform 1. The annular connecting cavity 41 is connected to the four collecting grooves 38. A filter plate 47 is arranged at the connection between the annular connecting cavity 41 and the collecting groove 38. Four lower through holes 42 are opened on the bottom inner wall of the annular connecting cavity 41. A purification box 45 is installed at the bottom of the cutting platform 1. An exhaust fan 46 is arranged on one side of the purification box 45. The purification The other side of the box 45 is connected to an annular conveying pipe 44, and the top of the annular conveying pipe 44 is connected to four lower collecting pipes 43, and the four lower collecting pipes 43 are respectively connected to the four lower perforations 42. A side sealing plate 51 is provided on the side of the collecting tank 38, and a push-pull rod 48 is rotatably installed on the end of the extrusion push rod 31, and a vertical moving rod 49 is rotatably installed on one end of the push-pull rod 48. The top of the vertical moving rod 49 extends into the collecting tank 38 and is fixedly installed with a filter scraper 50, which is in contact with one side of the filter plate 47. A first trigger block 52 is fixedly installed on one side of the arc frame 33, and a second trigger block 53 is fixedly installed on the side of the cutting platform 1. The first trigger block 52 is adapted to the second trigger block 53.

[0054] The exhaust fan 46 generates exhaust during operation. During the cutting process, the smoke generated above and the smoke passed through by the cutting below enter the collecting tank 38 from the side collecting holes 40 and the lower collecting holes 39 respectively, and the dust and impurities are filtered through the filter plate 47. The harmful gases generated by the cutting will enter the purification box 45 from the annular connecting cavity 41, the lower perforation 42, the lower collecting pipe 43, and the annular conveying pipe 44 in sequence, so as to purify the harmful gases and prevent the harmful gases generated during cutting from escaping into the air and affecting the physical and mental health of the workers. When the arc frame 33 is in contact and extrusion with the arc fixed block 34, the movement of the extrusion push rod 31 will drive the push-pull rod 48 to move, thereby driving the vertical moving rod 49 to move. The vertical moving rod 49 will drive the filter scraper 50 to move upward, and the filter scraper 50 will be moved upward before vacuuming. The filter plate 47 is cleaned once to ensure that the smoke and dust generated during the cutting process are effectively filtered. After cutting, as the cutting platform 1 rotates, the arc frame 33 separates from the arc fixed block 34, and under the elastic force of the reset spring 30, the filter scraper 50 is driven to reset. While resetting, the filter plate 47 can also be cleaned. When a large amount of dust and impurities are collected in the collection groove 38, the side sealing plate 51 is opened to scrape off the dust and impurities in the collection groove 38. After cutting is completed, the cutting platform 1 rotates again, and the cut steel plate body 8 will rotate to one side of the output belt 7, and the staff can take it away. During the cutting process, the steel plate body 8 does not need to be manually clamped by the staff, and the material discharge adjustment, clamping, cutting and dust collection operations are carried out in sequence, which is convenient to use.

[0055] Working principle of the present invention: When in use, when cutting large quantities of steel plate bodies 8 of the same specification, the material is transported through the material conveying component 5, and the steel plate body 8 transported in is placed on the cutting placement groove 3 in the front, and the stepper motor 4 is started to drive the cutting platform 1 to rotate. The rack 10 on the side of the cutting platform 1 will contact and engage with the gear 12, thereby driving the arc-shaped pushing block 14 above to rotate, and push the steel plate body 8 placed on the outside to the internal position, so as to avoid the problem that the placement position of the steel plate body 8 is inaccurate during the placement of the steel plate body 8 by the staff, thereby affecting the accuracy of the subsequent cutting.

[0056] At this time, the cutting platform 1 rotates again. During the rotation, the arc frame 33 contacts and squeezes the arc fixed block 34, which will drive the squeezing push rod 31 to move, and will drive the two linkage rods 32 to move, thereby driving the two guide blocks 22 to approach each other. The two clamping plates 24 automatically clamp the placed steel plate body 8, and automatically clamp and position the steel plate body 8 during the rotation process. There is no need for manual clamping operations by the staff, which reduces a lot of time occupied by clamping, and the clamping is more convenient and quick.

[0057] The first trigger block 52 contacts the second trigger block 53, and the drive motor 58 and the exhaust fan 46 are powered on. After the drive motor 58 is running, it drives the cutting head 61 to move to realize the cutting operation of the steel plate body 8. The exhaust fan 46 runs to generate exhaust. During the cutting process, the smoke and dust generated enters the collecting tank 38, passes through the filter plate 47 to filter dust and impurities, and finally enters the purification box 45 to purify the harmful gas, so as to avoid the harmful gas generated during cutting from escaping into the air and affecting the physical and mental health of the staff. The filter scraper 50 is set, and when the extrusion push rod 31 moves, it can drive the filter scraper 50 to move, clean the filter plate 47, and ensure that the smoke and dust generated during the cutting process is effectively filtered. After the cutting is completed, the cutting platform 1 rotates again, and the cut steel plate body 8 will rotate to one side of the output belt 7, and the staff can take it away. During the cutting process, the steel plate body 8 does not need to be manually clamped by the staff, so that the material discharge adjustment, clamping, cutting and dust collection operations are carried out in sequence, which is convenient to use.
