[0041] Example 1

[0042] like Figures 1 to 4 The flame cutting machine frame shown is arranged across multiple billet discharge ports. The flame cutting machine frame includes: two symmetrically arranged support frame assemblies 1, and multiple sets of crossbeams 2 located between the two support frame assemblies 1 and arranged along the billet discharge direction. Sliding rails are provided above the multiple sets of crossbeams 2 along the length of the crossbeams 2. The support frame assembly 1 includes a support beam 11 and columns 12 arranged at both ends of the support beam 11. The multiple sets of crossbeams 2 are arranged perpendicular to the support beam 11.

[0043] The two support beams 11 are respectively provided with an inlet channel 11a and an outlet channel 11b for the cooling medium to flow through. The multiple sets of crossbeams 2 are each provided with a diversion channel 2a that is connected to the inlet channel 11a and the outlet channel. A sealing plate 13 is provided at the end of the two support beams 11 on the same side. Multiple branch flow aid holes 11c are provided on the two support beams 11 and the multiple sets of crossbeams 2.

[0044] In the preferred embodiment of this utility model, the coolant enters the frame through the inlet channel 11a, flows through the branch channels 2a in the multiple crossbeams 2, and is finally discharged through the outlet channel 11b, thus forming a complete cooling circuit. While the cooling circuit is working, the branch flow aid holes 11c at different positions inject new coolant into the cooling circuit to further enhance the cooling effect.

[0045] This invention achieves uniform distribution of cooling medium within the frame through inlet channel 11a, outlet channel 11b, and diversion channel 2a, reducing guide rail deformation or damage caused by local overheating, extending the service life of the frame, and improving the cutting accuracy and stability of the fire cutter. Furthermore, the branch flow aid hole 11c helps improve the flow characteristics of the cooling medium, enabling the coolant to carry away heat more quickly and improving cooling efficiency.

[0046] To accelerate the flow rate of the cooling medium and further improve cooling efficiency, the inlet channel 11a is equipped with a guide pipe 3 along its centerline, and the guide pipe 3 is equipped with multiple support plates 4 along its length. The inlet channel 11a is divided by the multiple support plates 4 to form liquid collection areas 4a corresponding to multiple crossbeams 2. The guide pipe 3 is equipped with distribution holes corresponding to the positions of the multiple crossbeams 2, which communicate with the liquid collection areas 4a. The guide pipe 3 in the inlet channel 11a directly guides the coolant to the corresponding collection areas through the distribution holes. The coolant in the collection areas flows through the crossbeams 2 to the outlet channel 11b and is discharged from the outlet channel 11b.

[0047] In this invention, a first connecting flange 111 is provided at the bottom of both ends of the support beam 11 to connect with the column 12; this enhances the connection strength between the support beam 11 and the column 12, thereby improving the stability of the entire structure. Furthermore, the end of the support beam 11 is fixed to one side of the first connecting flange 111, which helps to disperse stress and reduce structural damage caused by concentrated loads.

[0048] As a preferred embodiment, the column 12 includes a body part 121 and two second connecting flanges 122 disposed at both ends of the body part 121. The body part 121 is vertically disposed and the end of the corresponding support beam 11 is eccentrically disposed, which can provide the support beam 11 with additional torsional and bending resistance, making the support more stable. In a further preferred structure, a heat insulation layer is disposed on the side of the support beam 11 facing the flame cutting head to avoid direct contact between the steel billet and the frame.

[0049] In a preferred embodiment of this invention, a flow sensor (not shown in the figure) and a water temperature sensor (not shown in the figure) are installed at the outlet of the outlet channel 11b. The flow sensor and the water temperature sensor are used to detect the flow rate and temperature of the cooling water to control the opening or closing of the branch flow aid orifice 11c. It should be noted that one or more flow sensors and water temperature sensors are installed on the frame to facilitate real-time and comprehensive monitoring of the cooling medium in the circulating cooling path.

[0050] In practice, an external controller and alarm are used to monitor water flow and temperature in real time. If an interruption in water flow or excessively high water temperature is detected, an alarm is issued promptly. The automated control system adjusts the opening or closing of the branch flow aid orifice 11c based on sensor data. Furthermore, since the coolant vaporizes at high temperatures, and the resulting gas can affect liquid flow, a pressure relief valve is installed at the outlet channel 11b. When the flow sensor detects an interruption in water flow, the pressure relief valve opens to release excess gas, thus ensuring normal coolant circulation.

[0051] By setting flow and water temperature sensors and using this data to control the opening or closing of the branch flow aid orifice 11c, the automation level, energy efficiency and overall performance of the fire-cutting machine cooling system can be improved, while reducing maintenance costs, extending equipment life and improving production efficiency.

[0052] Example 2

[0053] The difference from Embodiment 1 is that multiple return areas 4b of the inlet channel 11a and the outlet channel 11b are used to form a serial circulation loop in combination with the diversion path of the single tube beam 2. All other features are the same and will not be described in detail here.

[0054] like Figure 5 and Figure 7 As shown, multiple support plates 4 are provided in both the inlet channel 11a and the outlet channel 11b, and the multiple support plates 4 form a reflux area 4b at two adjacent crossbeams 2; a guide pipe 3 is provided in the inlet channel 11a, and the guide pipe 3 is connected to the reflux area 4b at the end position; the reflux areas 4b located in the inlet channel 11a and the outlet channel 11b are staggered, and the flow direction of the coolant in two adjacent crossbeams 2 is opposite.

[0055] In this embodiment, the inlet channel 11a, the outlet channel 11b and the crossbeam 2 form a single-pipe serial circulation, which allows the rapidly circulating cooling water to carry away heat in time and improve the heat dissipation effect.

[0056] As a preferred embodiment of the above, the guide pipe 3 located in the inlet channel 11a is configured as two sections, the two sections of the guide pipe 3 are located at different horizontal planes, and a buffer area 4k is formed at the drop.

[0057] The multi-segment guide tube structure, with a buffer zone 4k formed at different levels, can effectively control the flow rate of the cooling medium and ensure a more uniform flow rate in different areas of the fire cutting machine frame, thereby avoiding uneven cooling caused by excessively fast or slow flow rates.

[0058] Example 3

[0059] The difference from Embodiment 1 is that a labyrinthine cooling circuit is achieved by using a double-tube beam 2. All other features are the same and will not be described in detail here.

[0060] In the preferred embodiment of this solution, such as Figure 6 and Figure 7 As shown, both the inlet channel 11a and the outlet channel 11b are equipped with guide pipes 3, and the guide pipes 3 are equipped with multiple support plates 4 along their length.

[0061] Inside the inlet channel 11a, multiple support plates 4 sequentially form a first confluence area 4c, a second confluence area 4d, a third confluence area 4e, a fourth confluence area 4f, a fifth confluence area 4g, and a first end confluence area 4h. The support plate 4 at the end position is provided with a first through hole connecting the first end confluence area 4h and the fifth confluence area 4g.

[0062] Inside the outlet channel 11b, along the water outlet direction, multiple support plates 4 are sequentially provided with a second end confluence area 4i, a sixth confluence area 4m, and a seventh confluence area 4n. The support plate 4 at the end position is provided with a second through hole connecting the second end confluence area 4i and the sixth confluence area 4m.

[0063] Among them, the fifth confluence area 4g is connected to the sixth area through the crossbeam 2, the seventh confluence area 4n is connected to the fourth confluence area 4f through the crossbeam 2, the fourth confluence area 4f is connected to the third confluence area 4e through the crossbeam 2, the third confluence area 4e is connected to the second confluence area 4d through the crossbeam 2, the second confluence area 4d is connected to the first confluence area 4c through the crossbeam 2, and the first confluence area 4c is connected to the outlet through the crossbeam 2.

[0064] As a preferred embodiment of the above scheme, the multiple crossbeams 2 located in the middle position are provided with a flow path 2b and a return flow path 2c, and the ends of the flow path 2b and the return flow path 2c near the outlet channel 11b are closed, and their inlets and outlets are both located at one end of the inlet channel 11a.

[0065] The support plate 4 is set between the inlet and outlet of the crossbeam 2.

[0066] The cooling medium is directly guided to the first end convergence area 4h through the guide pipe 3, and then flows back into the fifth convergence area 4g through the first through hole. The crossbeam 2 guides the cooling medium in the fifth convergence area 4g to the sixth convergence area 4m, and then into the second end convergence area 4i through the second through hole. It continues to be guided to the seventh convergence area 4n through the guide pipe 3. The cooling medium in the seventh convergence area 4n is guided to the fourth convergence area 4f through the crossbeam 2. The fourth convergence area 4f, the third convergence area 4e, the second convergence area 4d, and the first convergence area 4c circulate sequentially through the dual-channel crossbeam 2, and finally is discharged into the outlet channel 11b through the unidirectional crossbeam 2. The multi-convergence area configuration, together with the bidirectional crossbeam 2, forms a labyrinthine cooling circuit, which makes the flow path of the cooling medium inside the rack longer, thereby enhancing the heat exchange efficiency and more effectively transferring heat from the rack to the cooling medium, thus improving the overall cooling efficiency.

[0067] Based on the above embodiments, preferably, a flow divider is provided at one end of the crossbeam 2 near the outlet channel 11b, and a guide pipe 3 is provided in the return flow path 2c. The end of the guide pipe 3 passes through the flow divider to ensure that the liquid flow direction is constant, avoid turbulence, and ensure uniform cooling.

[0068] As a preferred embodiment of the above, the guide pipe 3 located in the inlet channel 11a and the outlet channel 11b is configured as two sections, with the two sections of guide pipe 3 located at different horizontal planes, and forming a buffer area 4k at the drop point.

[0069] The multi-segment guide tube structure, with buffer zones 4k formed at different horizontal levels, effectively controls the flow rate of the cooling medium, ensuring a more uniform flow rate across different areas of the heat-cutting machine frame. This avoids uneven cooling caused by excessively fast or slow flow rates. This design also reduces pressure loss during cooling medium flow, improving the energy efficiency of the cooling system, reducing energy consumption, and achieving energy conservation and emission reduction. Furthermore, the multi-segment guide tube structure provides more adjustment points, allowing for flexible adjustment of the cooling medium's flow direction and flow rate according to actual needs, adapting to different working environments and conditions, and ensuring optimal cooling performance under various workloads and environmental changes.

[0070] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
