[0021] Furthermore, the support mechanism 4 also includes a reinforcing frame 46, a door 47, and a trough 48.

[0022] Specifically, the waterbed structure 2 includes a waterbed body 21, a first chamber 22, an extension chamber 23, and a filter plate 24. The waterbed body 21 facilitates the placement of the platform structure 6, allowing the SCR product to be welded inside the first chamber 22. Under the action of water, cutting slag and dust, driven by the cutting gas, are injected into the water and deposited, achieving a smokeless cutting effect and realizing environmentally friendly cutting operations. The extension chamber 23 facilitates the installation of a submersible pump. The extension chamber 23 is L-shaped, and a groove is cut into the cement floor at the L-shaped part to accommodate it. The filter plate 24 facilitates the filtration of water pumped from inside the extension chamber 23, preventing it from entering the extension chamber. Inside the extension chamber 23, the submersible pump is blocked. The submersible pump is installed inside the extension chamber 23, which facilitates the transfer operation inside the waterbed body 21. The filter plate 24 is provided with multiple filter holes.

[0023] To reduce the workload of cleaning slag from the waterbed, this equipment can also handle flame cutting of carbon steel plates under 40mm in thickness when the material feeding is uneven. Based on the existing underwater CNC precision plasma cutting machine's waterbed operation mode, platform structure 6 is placed in the waterbed, the steel plate to be cut is placed on platform structure 6, and water is injected into the waterbed body 21. The water level is adjusted according to the thickness of the plate being cut, remaining approximately 50-100mm below the lower surface of the steel plate (100-200mm for carbon steel plates). Slag and dust are injected into the water and deposited under the influence of the cutting gas, achieving a smokeless cutting effect. The No. 3 CNC flame and precision plasma cutting machine is modified to... The water bed creates a wet cutting process, where cutting slag and dust are injected into the water and deposited under the influence of cutting gas, thus providing a dust removal function. After the modification of the No. 3 CNC equipment, a flexible operation mode is adopted, which mainly uses fine plasma cutting for blanking and supplements it with flame cutting, based on production needs. This ensures the completion of the stainless steel blanking task for SCR, guarantees cutting quality and surface quality, meets environmental protection requirements, greatly improves production capacity, meets the increased demand for SCR orders, improves the quality of stainless steel parts cut edges, significantly improves the appearance quality of parts, improves the surface cleaning quality of parts, reduces the amount of grinding and cleaning work, lowers costs, and improves the overall appearance quality of SCR.

[0024] Specifically, the water tank structure 3 includes a base 31, a fixed pipe 33, a first pipe body 34, and a second pipe body 35. The base 31 provides support for the main body 32 of the water tank. The fixed pipe 33 connects to the connecting pipe 51 to allow water to drain from the inside of the main body 32. Valves are installed on both the first pipe body 34 and the second pipe body 35, allowing access to the inside of the main body 32 as needed, and serving as backup pipes. The main body 32 is fixedly connected to the top of the base 31, and compressed water is injected into the main body 32 through the auxiliary pipe 55. Air and water in the main body 32 of the water tank are compressed into the first cavity 22 of the main body 21 of the water bed through the fixed pipe 33, connecting pipe 51, water inlet pipe 52 and connecting pipe 53, raising the water level inside the first cavity 22. When the compressed air in the main body 32 of the water tank is released, water from the water bed flows into the main body 32 of the water tank, lowering the water level inside the first cavity 22, thereby playing the role of water level regulation and recycling. The fixed pipe 33 is fixedly sleeved on the side of the main body 32 of the water tank, and the first pipe 34 and the second pipe 35 are both fixedly sleeved on the side of the main body 32 of the water tank.

The auxiliary pipe 55 can be used in conjunction with an external compression device to allow compressed air to enter the interior of the water tank body 32, thereby expelling the water inside, or to vent the water tank body 32. It should be noted that a piston can be installed inside the water tank body 32, with air and water located on opposite sides of the piston. When gas enters, it pushes the piston forward to expel the water. When gas is expelled, the water pressure pushes the piston backward. The outlet pipe 54 is fixedly inserted into the side of the water bed body 21 and extends to the isolation plate 42. One end of the outlet pipe 54 is located on the side of the isolation plate 42, and an auxiliary valve is installed on the outlet pipe 54.

[0029] Specifically, the auxiliary components include a first perforated plate 66 and a second perforated plate 67. There are two of each of the first perforated plate 66 and the second perforated plate 67, so that the cutting slag can fall from its holes into the interior of the first cavity 22, which facilitates environmentally friendly cutting operations. The first perforated plate 66 is fixedly connected to the interior of the frame 61, and the second perforated plate 67 is fixedly connected to the interior of the frame 61.
