Description

Technical Field

[0001] The utility model relates to a flame cutting machine, in particular to a directional rotary swing flame cutting machine. Background Art

[0002] As the last step in the steelmaking continuous casting process, flame cutting requires a flame cutting machine to cut it into the required fixed length. The structure, corresponding cutting method, reliability and performance of the continuous casting cutting device are important factors to improve the production efficiency of steelmaking continuous casting cutting. Cutting steel billets affects both the cutting speed and the energy consumption of cutting to varying degrees. However, the existing continuous casting cutting device has a different structure and setting method. The same continuous casting machine pulls steel billets of different shapes, and different flame cutting machines need to be replaced for cutting. The billet cutting uses a rectangular billet cutting machine that is close to the maximum size, which affects the cross-section cutting quality, wastes energy consumption, increases the labor intensity of workers, and has a high production cost. Utility Model Content

[0004] The technical scheme of the utility model is: a directional rotary swing flame cutting machine, the flame cutting machine comprises a drag chain plate, a granulated water device, a frame assembly, a cutting gun, a cutting nozzle, a limit device, a position measuring device, a trolley walking device, a front baffle, a cutting gun swing device and a synchronization mechanism;

[0005] The synchronization mechanism is arranged on the frame assembly, the cutting gun swinging device is fixedly connected to the frame assembly, the trolley walking device is connected to the position measuring device and is arranged on the frame assembly, the frame assembly is connected to the front baffle, the cutting gun and the cutting nozzle are respectively installed on the cutting gun swinging device, the granulated water device is connected to the front baffle, and the drag chain plate is fixedly connected to the upper part of the frame assembly.

[0006] Furthermore, the granulated water device is arranged at the front end of the front baffle and is on the same horizontal line as the cutting gun.

[0007] Furthermore, the limit device is composed of four proximity switches, two of which are respectively installed on the frame assembly to control the forward and backward travel stop position of the trolley walking device; the other two proximity switches are respectively installed in the frame assembly to control the left and right swing position of the cutting gun swing device.

[0008] Furthermore, the position measuring device comprises a sprocket and an encoder, the sprocket is connected to a trolley travel device, and the position measuring device monitors the moving speed, time and distance of the flame cutting machine.

[0009] Furthermore, the synchronization mechanism is arranged at the front end of the frame assembly, and the synchronization mechanism clamps the steel billet and moves synchronously with the steel billet.

[0010] The beneficial effects of the utility model are: the swing amplitude is adjusted by using proximity switch induction to achieve cutting of different billet types, and the synchronization mechanism is installed at the front of the fire cutting machine. The synchronization mechanism at the front of the entire fire cutting machine also reduces the impact force when clamping the billet. The path of the billet cutting process is mainly completed by the synchronous movement of the billet and the synchronous movement of the billet. If a billet with a different cross-section is replaced, it is necessary to adjust the sensing distance of the cutting gun swing device in time to complete the swing amplitude of the cutting gun swing device and cut different billets.

[0011] The utility model can be realized by controlling various electrical components and corresponding PLC programs, and can control the swing amplitude of the cutting gun swing device in real time to realize the cutting of different steel billets, so that this type of flame cutting machine can be used on a production line for cutting various steel billet sections.

[0012] The utility model can fully realize the diversified operation of the pre-clamping opening of the synchronous mechanism and the requirements for different steel billet sections are constantly improved, and the technology is also valued, and it is an indispensable tool for various steel plants.
