Description

Technical Field

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

[0002] Thicker metal plates mostly require flame cutting when cutting. Flame cutting uses the high temperature generated during the combustion of iron oxide to cut carbon steel. The design of the flame cutting torch provides sufficient oxygen for the combustion of iron oxide to ensure a good cutting effect. Flame cutting equipment has low cost and is the only economical and effective means of cutting thick metal plates. There are two flame cutting methods: torch cutting and cutting machine cutting.

[0003] Cutting torch is also called flame gun. Different fuel gas is used and the structure is also different. Commonly used is oxygen-acetylene flame gun. The pressure of acetylene is 0.01~0.12MPa, and the pressure of oxygen is 0.50~1.0MPa. The two gases are mixed and burned in the flame gun through their own passages. The size and nature of the ejected flame can be adjusted. Manual handheld flame gun is used for cutting. It is usually used for cutting large pipe billets and slabs after rolling or for supplementary cutting to remove defects after steel straightening.

[0004] In the prior art, when factories use cutting torches, they usually place the cutting torch equipment on a self-propelled trolley, place a guide rail directly above the metal plate, and move the self-propelled trolley on the guide rail, so that the cutting torch equipment finally completes the cutting work on the metal plate. However, since the guide rail is simply placed above the metal plate and there is a lack of fixed structure at both ends, the cutting torch equipment has poor stability when moving, which affects the cutting effect.

[0005] Therefore, it is necessary to provide a new cutting device for metal structure manufacturing to solve the above technical problems. Summary of the invention

[0022] In the specific implementation process, Figure 1-Figure 7As shown, it includes a storage table 1, and a trapezoidal base 2 is arranged on both sides of the storage table 1. Two load-bearing columns 3 are symmetrically fixed on the trapezoidal base 2, and a plurality of through holes 4 are spaced apart on the load-bearing columns 3. Adjustment seats 9 are slidably arranged at the two pairs of load-bearing columns 3, and the adjustment seats 9 are fixedly connected with two guide rails 5. Two pairs of limit seats 10 are fixed on the adjustment seats 9 at intervals, and the limit seats 10 and the load-bearing columns 3 are fixedly connected by high-strength bolts 11. When the present cutting device is used, the staff can adjust the height of the guide rail 5 and the movable table 7 according to the thickness of the metal sheet to be cut. It is only necessary to use a hydraulic jack to prop up the two adjustment seats 9 and remove the high-strength bolts 11. At this time, the height of the two adjustment guide rails 5 can be adjusted along the load-bearing columns 3. After the adjustment is completed, the high-strength bolts 11 are passed through the limit seats 10 and the corresponding through holes 4, and finally connected with the corresponding nuts to complete the fixing of the adjustment seats 9. By fixing the adjustment seats 9 at both ends of the guide rails 5, the stability of the cutting mechanism during use can be greatly improved.

[0023] Two guide rails 5 are arranged at intervals above the storage table 1. The two guide rails 5 are fixedly connected by a plurality of connecting rods 6. A moving platform 7 is slidably arranged on the two guide rails 5. A cutting mechanism is arranged on the moving platform 7. The cutting mechanism includes a cutting torch 8 and a gas supply device 31. The core principle of flame cutting is to use the high-temperature flame generated by the mixed combustion of oxygen and combustible gas such as acetylene, propane or hydrogen to heat the metal surface to its melting point or ignition point by high temperature, and then oxidize the metal and remove the cut part by the injection of oxygen flow, so as to achieve cutting. The main equipment of flame cutting includes gas cylinder, cutting nozzle, flame control valve, gas pressure gauge and flow meter. Common gas cylinders include oxygen cylinder and combustible gas cylinder such as acetylene cylinder. Oxygen provides the necessary oxygen supply, and acetylene or other combustible gases provide sufficient combustion energy. The nozzle is used to control the shape, size and flow rate of the flame. According to the cutting requirements of different materials, the nozzle can have different designs. The gas pressure gauge and flow meter are used to detect and adjust the gas flow and pressure to ensure the stability of the cutting process.

[0024] A side seat 12 is fixed between the two adjustment seats 9, and a rack 13 is installed on the side seat 12. A first mounting seat 14 is fixed on one side of the movable platform 7, and a first rotating shaft 15 is movably provided on the first mounting seat 14. A displacement gear 16 is installed on the first rotating shaft 15, and the displacement gear 16 is meshed with the rack 13. When the displacement gear 16 rotates, it can drive the movable platform 7 to move along the guide rail 5. The corresponding motor is started to drive the displacement gear 16 to rotate. Under the transmission action of the displacement gear 16 and the rack 13, the entire movable platform 7 will drive the cutting mechanism to stably displace along the guide rail 5, further improving the stability of the cutting torch 8 during cutting and improving the cutting effect.

[0026] A transmission worm wheel 27 is installed on each of the two lifting screws 17, and the transmission worm wheel 27 is meshed with the multi-head worm 26. A closed transmission is adopted between the transmission worm wheel 27 and the multi-head worm 26, which is dustproof and waterproof, and its service life is improved.

[0028] After the flame cutting is completed, the staff can start the electric telescopic rod 28 to drive the driving block 30 to move. Under the action of the electric telescopic rod 28, the connecting swing rod 29 will be driven to rotate, thereby causing the support shaft 20 to rotate accordingly. Under the action of the support shaft 20, the swing seat 21 will rotate to a position vertical to the guide rail 5, and the starting motor will drive the multi-head worm 26 to rotate. Under the action of the multi-head worm 26 and the transmission worm wheel 27, the two lifting screws 17 will rotate in the same direction at the same time, which will drive the lifting platform 19 to move downward along the sliding column 18. At this time, the support plate 23 will also move downward. When the grinding iron brush 24 contacts the cutting surface of the plate, the grinding iron brush 24 will remove the "black skin (the black skin during flame cutting is mainly the result of the combined action of iron oxide generated by oxidation reaction and other incompletely burned carbon substances)" remaining on the cutting surface, and the staff no longer needs to manually use a shovel to shovel it away, thereby reducing processing time and improving work efficiency. A collecting box 32 is provided below the cutting torch 8 for recovering the molten iron generated during flame cutting. The collecting box 32 is made of cast iron to ensure that the collecting box 32 will not be melted or damaged due to high temperature.

[0029] Working principle of the present invention: When the present cutting device is used, the staff can adjust the height of the guide rail 5 and the movable platform 7 according to the thickness of the metal plate to be cut. It is only necessary to use the hydraulic jack to prop up the two adjustment seats 9 and remove the high-strength bolts 11. At this time, the height of the two adjustment guide rails 5 can be adjusted along the load-bearing column 3. After the adjustment is completed, the high-strength bolts 11 are passed through the limit seats 10 and the corresponding through holes 4, and finally connected with the corresponding nuts to complete the fixing of the adjustment seats 9. By fixing the adjustment seats 9 at both ends of the guide rails 5, the stability of the cutting mechanism during use can be greatly improved; The corresponding motor is started to drive the displacement gear 16 to rotate. Under the transmission effect of the displacement gear 16 and the rack 13, the entire moving platform 7 will drive the cutting mechanism to move stably along the guide rail 5, further improving the stability of the cutting torch 8 during cutting and improving the cutting effect; After the flame cutting is completed, the staff can start the electric telescopic rod 28 to drive the driving block 30 to move. Under the action of the electric telescopic rod 28, the connecting rocker 29 will be driven to rotate, and then the support shaft 20 will rotate accordingly. Under the action of the support shaft 20, the rocker seat 21 will rotate to a position vertical to the guide rail 5, and the starting motor will drive the multi-head worm 26 to rotate. Under the action of the multi-head worm 26 and the transmission worm wheel 27, the two lifting screws 17 rotate in the same direction at the same time, which will drive the lifting platform 19 to move downward along the sliding column 18. At this time, the support plate 23 will also move downward. When the grinding iron brush 24 contacts the cutting surface of the plate, the grinding iron brush 24 will remove the "black skin" remaining on the cutting surface, and the staff no longer needs to manually use a shovel to shovel it away, thereby reducing processing time and improving work efficiency.
