Description

Technical Field

[0001] This utility model relates to the field of laser plasma cutting machine technology, specifically to a laser cutting plasma cooling fluid circulation device. Background Technology

[0002] Laser plasma cutting machines are high-efficiency, precision metal cutting equipment that combines laser and plasma technologies. They are mainly used in industrial fields such as shipbuilding, bridge construction, and machinery manufacturing. They feature high precision and high speed, are unaffected by the hardness of the material being cut, and can process steel plates, stainless steel, aluminum alloy plates, and cemented carbide, among others. The cut edges are minimally affected by heat, resulting in virtually no workpiece thermal deformation. This completely avoids edge collapse that occurs during material punching and shearing, and the cut generally does not require secondary processing, making them suitable for a variety of industrial applications.

[0003] Currently, when using laser plasma cutting machines, the cutting head generates high temperatures, which often require cooling with coolant. However, existing coolant circulation equipment suffers from significantly reduced cooling efficiency due to the rapid circulation of the coolant. The heat carried by the coolant is difficult to dissipate quickly, and it tends to flow back to the cutting head, resulting in poor cooling and continuous overheating of the cutting head, which affects safety. Utility Model Content

[0004] The purpose of this invention is to provide a laser cutting plasma coolant circulation device. By installing a heat dissipation component inside the second storage tank, the heat dissipation component consists of multiple sets of inclined and staggered heat-conducting plates. This allows the returning high-temperature coolant to flow sequentially onto each heat-conducting plate. Combined with heat dissipation fins, heat can be dissipated outside the tank. The long flow path of the coolant greatly extends the heat dissipation time. At the same time, multiple sets of partition plates are arrayed on the heat-conducting plates to further distribute the coolant evenly on the heat-conducting plates, thereby improving the heat conduction effect. This effectively dissipates heat and greatly ensures the circulating cooling effect of the coolant, thus solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser cutting plasma cooling fluid circulation device, comprising:

[0006] A fixed frame is provided with a first liquid storage tank at one inner end and a second liquid storage tank at the other inner end. A liquid pump is provided at the bottom end of the fixed frame near the first liquid storage tank. One end of the liquid pump is connected to the first liquid storage tank through a pipe, and the other end of the liquid pump is provided with a first connecting pipe. A second connecting pipe is provided on the top side of the second liquid storage tank, and a flow diversion component is provided between the second liquid storage tank and the first liquid storage tank.

[0007] A cooling jacket is installed outside the cutting head, with an inlet hose connected to the cooling jacket and an outlet hose connected to the cooling jacket. The bottom end of the inlet hose is connected to a first connecting pipe, and the bottom end of the outlet hose is connected to a second connecting pipe. A heat dissipation component is provided on the second liquid storage tank.

[0008] Preferably, the heat dissipation assembly includes multiple heat-conducting plates symmetrically arranged on both sides inside the second liquid storage tank. One end of each heat-conducting plate extends outside the second liquid storage tank and is connected to heat dissipation fins. The multiple heat-conducting plates are distributed at an inclined and staggered angle.

[0009] Preferably, the top side of the heat-conducting plate is arrayed with multiple partition plates, and the tops of the two outermost partition plates are inclined outward.

[0010] Preferably, the ends of both the heat-conducting plate and the partition plate are provided with rounded chamfers.

[0011] Preferably, the diversion assembly includes a booster pump located at the bottom of the fixed frame near the second liquid storage tank. One end of the booster pump is connected to the second liquid storage tank via a pipe, and the other end of the booster pump is connected to a liquid supply pipe. Multiple spiral pipes are arranged in an array between the liquid supply pipe and the first liquid storage tank.

[0012] Preferably, a cooling fan facing the spiral pipe is provided on one side of the bottom end of the fixing frame.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] By installing a heat dissipation component inside the second liquid storage tank, which consists of multiple sets of inclined and staggered heat-conducting plates, the high-temperature coolant flowing back can flow sequentially onto each heat-conducting plate. Combined with the heat dissipation fins, heat can be dissipated to the outside of the tank. The long flow path of the coolant can greatly extend the heat dissipation time. At the same time, multiple sets of partition plates are arrayed on the heat-conducting plates, which can further distribute the coolant evenly on the heat-conducting plates to improve the heat conduction effect. Thus, heat can be effectively dissipated, greatly ensuring the circulating cooling effect of the coolant.

[0015] By setting a flow distribution component between the second and first liquid storage tanks, the flow distribution component consists of a liquid supply pipe and multiple sets of spiral pipes. With the help of a cooling fan, the coolant can move spirally in each spiral pipe and exchange heat with the cold air, thereby further cooling the coolant. Finally, it can flow back into the cooling jacket to cool the cutting head, thus greatly improving the circulating cooling effect. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1-5 The laser cutting plasma coolant circulation device shown includes:

[0026] A fixed frame 1 is provided with a first liquid storage tank 2 at one end of its inner side and a second liquid storage tank 3 at the other end of its inner side. A liquid pump 7 is provided at the bottom end of the fixed frame 1 near the first liquid storage tank 2. One end of the liquid pump 7 is connected to the first liquid storage tank 2 through a pipe, and the other end of the liquid pump 7 is provided with a first connecting pipe 8. A second connecting pipe 9 is provided on the top side of the second liquid storage tank 3, and a diversion component is provided between the second liquid storage tank 3 and the first liquid storage tank 2.

[0027] Cooling jacket 6 is installed on the outside of the cutting head. The inlet of cooling jacket 6 is connected to a liquid inlet hose 4, and the outlet of cooling jacket 6 is connected to a liquid outlet hose 5. The bottom end of the liquid inlet hose 4 is connected to the first connecting pipe 8, and the bottom end of the liquid outlet hose 5 is connected to the second connecting pipe 9. The second liquid storage tank 3 is equipped with a heat dissipation component.

[0028] The heat dissipation assembly includes multiple heat-conducting plates 13 symmetrically arranged on both sides inside the second liquid storage tank 3. One end of each heat-conducting plate 13 extends outside the second liquid storage tank 3 and is connected to heat dissipation fins 15. The multiple heat-conducting plates 13 are distributed in an inclined and staggered manner.

[0029] The top side of the heat-conducting plate 13 is provided with a plurality of partition plates 14, and the tops of the two outermost partition plates 14 are inclined outward.

[0030] In use, the coolant in the first storage tank 2 can be pumped into the first connecting pipe 8 by the pump 7, and then sent into the cooling jacket 6 by the inlet hose 4. The cooling jacket 6 can exchange heat with the cutting head. Then the coolant carries the high temperature heat into the outlet hose 5, and then enters the second storage tank 3 through the second connecting pipe 9.

[0031] Afterwards, the high-temperature coolant can flow sequentially through each heat-conducting plate 13 in the second reservoir 3. During the flow, the heat-conducting plate 13 can transfer heat to the heat dissipation fins 15, and then the heat dissipation fins 15 can dissipate it to the outside of the second reservoir 3. The long flow path of the coolant can greatly extend the heat dissipation time. Furthermore, the multiple sets of partition plates 14 on the heat-conducting plate 13 can further make the coolant evenly distributed on the heat-conducting plate 13 to improve the heat conduction effect, thereby effectively dissipating the heat and greatly ensuring the circulating cooling effect of the coolant.

[0032] Both the heat-conducting plate 13 and the partition plate 14 have rounded chamfers at their ends.

[0033] The diversion assembly includes a booster pump 10 located at the bottom of the fixed frame 1 near the second liquid storage tank 3. One end of the booster pump 10 is connected to the second liquid storage tank 3 through a pipe, and the other end of the booster pump 10 is connected to a liquid supply pipe 11. Multiple spiral pipes 12 are arranged in an array between the liquid supply pipe 11 and the first liquid storage tank 2.

[0034] A cooling fan 16 facing the spiral pipe 12 is provided on one side of the bottom end of the mounting bracket 1.

[0035] After the coolant flows to the bottom of the second reservoir 3, it can be pumped into the supply pipe 11 by the booster pump 10, and then sent to each spiral pipe 12. During the spiral movement in the spiral pipe 12, heat can be dissipated again. In addition, the cold air blown out by the cooling fan 16 can greatly enhance the heat exchange effect between the spiral pipe 12 and the cold air, thereby further cooling down the coolant. Finally, the low-temperature coolant enters the first reservoir 2 and can be drawn out by the pump 7 to cool the cutting head, thereby greatly improving the circulating cooling effect.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
