Description

Technical Field

[0001] This utility model belongs to the technical field of flame cutting machines, specifically referring to a fast and efficient flame cutting machine. Background Technology

[0002] As a core piece of equipment in the metal processing field, flame cutting machines are widely used in batch cutting operations of materials such as steel plates and structural steel due to their advantages of wide cutting range and controllable cost.

[0003] Currently, the protection of flame cutting machines is mostly concentrated on the overall periphery of the equipment, lacking specific protection around the cutting head. There are no targeted protective structures on the front and back sides of the cutting head, and the high-temperature sparks and molten slag generated during the cutting process can easily splash forward and backward. Since operators mostly observe and operate from the front and back sides, the splashing sparks can easily burn the operators and may also ignite nearby stacked materials such as boards and cables, posing a serious safety hazard. Utility Model Content

[0004] The present invention aims to provide a fast and efficient flame cutting machine that solves the above-mentioned technical problems.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A fast and efficient flame cutting machine includes a cutting table and a flame cutting nozzle movably arranged above the cutting table; it also includes a support frame arranged in an inverted U-shape on the cutting table, a slider is slidably arranged in a semi-enclosed manner on the upper part of the support frame, and a driving component is connected to the bottom of the slider for moving and adjusting the flame cutting nozzle; side plates are fixed to the two side walls of the slider, and a protective baffle is movably arranged at the bottom of the side plate, and a lifting component is provided on the side plate for raising and lowering the protective baffle.

[0006] Preferably, the top wall of the protective baffle is provided with a movable groove, and the side plate is movably inserted into the movable groove.

[0007] Furthermore, the drive assembly includes a lead screw and a connecting block. The lead screw is rotatably mounted at the bottom of the support frame. One end of the lead screw is axially connected to a motor mounted on the outer wall of the support frame. The connecting block is fixed to the bottom of the slider and threadedly connected to the lead screw. The flame cutting nozzle is mounted on the bottom wall of the connecting block.

[0008] Furthermore, the lifting assembly includes a lifting groove and a fixing block. The lifting groove is opened on the side plate, and a second lead screw is rotatably installed in the lifting groove. The fixing block is fixed to the side wall of the movable groove and threadedly connected to the second lead screw. An electric motor installed on the top wall of the side plate is axially connected to the top of the second lead screw.

[0009] Furthermore, the top wall of the protective baffle is provided with a slag-blocking plate to protect the inside of the lifting trough.

[0010] The beneficial effects achieved by adopting the above-described structure are as follows: 1. The protective baffles on both sides of the slider can specifically cover the front and rear sides of the flame cutting nozzle, directly blocking the high-temperature sparks and molten slag splashed during the cutting process, solving the problem of insufficient protection around the cutting head by the external protection of traditional equipment; 2. The electric motor drives the lead screw to rotate, which in turn drives the fixed block and the protective baffle to rise and fall along the side plate. With the guide of the movable groove of the protective baffle and the side plate, the protective height can be stably adjusted. The height of the protective baffle can be flexibly adjusted according to the cutting requirements of materials of different thicknesses. At the same time, the motor drive can save a lot of operation time compared with manual adjustment, and meet the high-efficiency operation requirements of batch continuous cutting. 3. The protective baffle moves synchronously with the slider and the flame cutting nozzle. When the cutting nozzle moves and cuts under the drive of the drive component, the protective baffle always covers the cutting area, and there is no need to adjust the position of the protective baffle.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] like Figure 1-4 As shown, the present invention proposes a fast and efficient flame cutting machine, including a cutting table 1 and a flame cutting nozzle 2 movably disposed above the cutting table 1; it also includes a support frame 3 arranged in an inverted U-shape on the cutting table 1, a slider 4 slidably disposed on the upper half of the support frame 3, and a drive assembly 5 connected to the bottom of the slider 4 for moving and adjusting the flame cutting nozzle 2; the drive assembly 5 includes a lead screw 10 and a connecting block 11, the lead screw 10 is rotatably disposed at the bottom of the support frame 3, one end of the lead screw 10 is axially connected to a motor 12 mounted on the outer wall of the support frame 3, and the lead screw 10 is threadedly connected to the connecting block 11 which is fixedly connected to the slider 4, and the flame cutting nozzle 2 is mounted on the bottom wall of the connecting block 11; After the main power is turned on, the cutting parameters are input through the control system. The system automatically matches the gas ratio of the flame cutting nozzle 2 with the transmission speed of the lead screw 10 (the control system, circuit connection, gas pipeline valves, and other structures are all existing technologies and will not be described in detail here). The slider 4 is reset to the initial position. The workpiece to be cut is placed on the cutting table 1 and fixed (it can be fixed by bolts or by electric push rod pushing and pressing). The motor 12 is started, which drives the lead screw 10 to rotate. The lead screw 10 drives the connecting block 11 to move, so that the connecting block 11 drives the flame cutting nozzle 2 to move. After the flame cutting nozzle 2 moves above the workpiece to be cut, the control system opens the gas valve and ignition device of the flame cutting nozzle 2 in conjunction. Cutting begins as the flame cutting nozzle 2 moves.

[0017] like Figure 3As shown, side plates 6 are fixed to both sides of the slider 4. A protective baffle 7 is movably provided at the bottom of the side plate 6. A movable groove 9 is provided on the top wall of the protective baffle 7. The side plate 6 is movably inserted into the movable groove 9. A lifting assembly 8 is provided on the side plate 6 for adjusting the lifting of the protective baffle 7. The lifting assembly 8 includes a lifting groove 13 and a fixing block 14. The lifting groove 13 is provided on the side plate 6. A second lead screw 15 is rotatably provided in the lifting groove 13. The fixing block 14 is fixed to the side wall of the movable groove 9 and threadedly connected to the second lead screw 15. An electric motor 16 installed on the top wall of the side plate 6 is axially connected to the top of the second lead screw 15. The operator inputs the target height of the protective baffle 7 according to the thickness of the material to be cut through the equipment control system. After receiving the instruction, the system supplies power to the electric motor 16 on the top wall of the side plate 6. The electric motor 16 starts and drives the lead screw 15 to rotate in the lifting groove 13 of the side plate 6. Since the fixed block 14 is fixed to the side wall of the movable groove 9 of the protective baffle 7 and threadedly connected to the lead screw 15, when the lead screw 15 rotates, it drives the fixed block 14 to move up and down along the lead screw 15. The protective baffle 7 rises and falls synchronously. The encoder on the lead screw 15 feeds back displacement data to the control system in real time. When the protective baffle 7 reaches the set height, the system automatically cuts off the power to the electric motor 16. The lead screw 15 uses the self-locking characteristic of the thread to fix its position. The protective baffle 7 maintains the target height. During the cutting process, the protective baffle 7 moves synchronously with the slider 4 and the flame cutting nozzle 2, always forming protection for the front and rear sides of the cutting area.

[0018] like Figure 2 As shown, the top wall of the protective baffle 7 is provided with a slag baffle 17 to protect the inner side of the lifting groove 13. This can prevent the slag that splashes during the cutting process from entering the lifting groove 13 of the side plate 6, effectively preventing the accumulation of slag from causing the lifting structure to jam, and further ensuring the safety of protection and equipment operation.

[0019] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
