Description

Technical Field

[0001] The utility model relates to the technical field of steel plate cutting, in particular to a super-thick steel plate cutting device. Background Art

[0002] The dimensions of ultra-thick steel plates vary depending on the application area, but generally speaking, their thickness, width and length are relatively large. The following is a specific description of the dimensions of ultra-thick steel plates: Thickness, definition range: In steel structure engineering, ultra-thick plates usually refer to plates with a thickness greater than that of ordinary components, generally greater than 100mm. There are also claims that the thickness of ultra-thick steel plates is between 60-115mm, and can even reach more than 500mm. These differences may be due to different industry standards and specific application requirements. Ultra-thick steel plates are widely used in large-span and large-space construction projects such as stadiums, airport terminals, etc. due to their excellent load-bearing capacity and structural stability. They are also used in heavy equipment and structures such as bridges, cranes, and oil rigs.

[0003] Ultra-thick steel plates are generally cut using a flame cutting machine. Current flame cutting machines, such as those disclosed in Chinese patent publication number CN220196570U, include a workbench, a cutting torch, a gas supply system, a temperature sensor, and a control module. The cutting torch is mounted on the workbench. The gas supply end of the gas supply system is connected to the cutting torch for delivering combustible gas. The temperature sensor is used to monitor the temperature of the cutting torch nozzle. The output end of the temperature sensor is electrically connected to the input end of the control module, and the output end of the control module is electrically connected to the control end of the gas supply system. The temperature sensor detects the temperature of the cutting torch nozzle and feeds back the temperature data to the control module. When the cutting nozzle temperature exceeds a preset temperature threshold, the control module controls the gas supply system to stop delivering combustible gas, causing the cutting torch to shut down, thereby preventing the cutting nozzle from heating up further and causing tempering.

[0004] Although the above-mentioned flame cutting machine solves the corresponding technical problems, it can only cut one side of the ultra-thick steel plate when used to cut it, which takes a long time. If it is not cut, it is necessary to turn it over and cut the other side of the ultra-thick steel plate again. If the previous incision is not accurately aligned, the cut flatness will be poor, affecting the cutting efficiency and cutting quality. Therefore, an ultra-thick steel plate cutting device is proposed. Utility Model Content

The cutting machine integrates key components such as a crisscross frame 2, a gantry 3, top support wheels 4, adjustable side support wheels 5, a flame cutting assembly 6, and a positioning mechanism 7, which work together to complete the cutting task.

[0049] T-shaped frame 2: serves as the main structure, supporting the entire cutting machine and connecting other components.

[0050] Gantry 3: It is fixedly installed at both ends of the crisscross frame 2 to provide additional support and stability, and is also installed with adjustable side support wheels 5.

[0051] Top support wheel 4: through the combination of vertical rod 401, wheel frame 1 402 and roller 1 403, it is pressed on the top of the ultra-thick steel plate 1 to support the cutting machine to move smoothly on the ultra-thick steel plate 1.

[0052] Adjustable side support wheels 5: Through the combination of the horizontal square rod 501, the second wheel frame 502, the second roller 503 and the third electric push rod 504, the cutting machine is limited to prevent it from tilting and adapting to ultra-thick steel plates 1 of different thicknesses.

[0053] The flame cutting assembly 6 is composed of an electric push rod 1 601 , an electric push rod 2 602 and a cutting torch 603 . The position of the cutting torch is adjusted by telescoping the electric push rod to achieve flame cutting of the ultra-thick steel plate 1 .

[0054] Positioning mechanism 7: It is composed of electric push rod 4 701 and pressing plate 702. The electric push rod 4 is extended and driven to press the pressing plate to press the extra-thick steel plate 1, which plays a braking positioning role to ensure that the cutting machine does not move during cutting.

[0055] Workflow:

[0056] 1. Preparation stage:

[0057] Place the extra-thick steel plate 1 vertically.

[0058] According to the thickness of the extra-thick steel plate 1 , the distance between the rollers 2 503 of the two sets of adjustable side support wheels 5 on the same gantry 3 is adjusted by the electric push rod 3 504 .

[0059] The entire device is in accordance with Figure 7 As shown, it is placed on a vertically placed extra-thick steel plate 1, so that the cutting machine can move smoothly on the extra-thick steel plate 1.

[0060] 2. Positioning stage:

[0061] The electric push rod 4 701 drives the pressing plate 702 to press on the top of the steel plate, playing a braking and positioning role.

[0062] 3. Cutting stage:

[0063] The vertical height of the cutting torch 603 is adjusted by an electric push rod 601.

[0064] The distance between the cutting torch 603 and the side of the extra-thick steel plate 1 is adjusted by the electric push rod 602 to ensure that it is appropriate.

[0065] Start the flame cutting assembly 6, and at the same time drive the cutting torch 603 downward through the electric push rod 601 to cut the extra-thick steel plate 1 up and down;

[0066] 4. Ending stage:

[0067] After the cutting is completed, the flame cutting assembly 6 is closed.

[0068] The cutting torch 603 is retracted to the initial position by the electric push rod 1 601 and the electric push rod 2 602 .

[0069] The electric push rod 4 701 drives the clamping plate 702 to loosen the extra-thick steel plate 1 and move the cutting machine away from the extra-thick steel plate 1.

[0070] From the above working principle and process, it can be seen that this ultra-thick steel plate cutting device can achieve efficient and high-quality double-sided cutting of ultra-thick steel plates.
