[0002] Plasma cutting torches solve the problem of high-speed cutting of highly conductive metals by converting electrical energy into ultra-high-temperature plasma jets. The core technology lies in the arc compression mechanism and high-temperature gas dynamics control. With the development of precision and environmental protection, metal processing equipment has become an indispensable key piece of equipment in modern metal processing.

[0003] During normal use, the cutting tip of a plasma cutting torch experiences a rapid increase in local temperature due to prolonged cutting operations. This can trigger a series of cascading technical malfunctions and process failures, leading to nozzle failure, motor collapse, and sealing system disintegration. Therefore, rapid cooling is necessary. However, most currently used water-cooling structures are quite large, which makes the device inconvenient to use. Alternatively, the water-cooling structure may be directly welded to the plasma cutting torch, making subsequent maintenance difficult and hindering normal operation.

[0004] Therefore, how to design a new plasma cutting torch with a water-cooled structure is a technical problem that engineers need to solve. Utility Model Content

[0021] The technical solution of the present invention (Embodiment 1) is described in detail below with reference to the accompanying drawings.

[0022] See Figure 1 , Figure 2 , Figure 3 and Figure 4The plasma cutting torch with a water-cooled structure specifically includes: a mounting base 1, an outer cover 2 mounted on one end of the mounting base 1, a mounting ring 3 sleeved inside the outer cover 2, a nozzle 4 fixedly mounted on the end of the mounting ring 3 near the outer cover 2, a mounting sleeve 5 inserted into the mounting ring 3 and the nozzle 4, and one end of the mounting sleeve 5 engaging with the end of the nozzle 4, an electrode 6 fixedly mounted inside the nozzle 4; a cooling mechanism, including a return groove 7 opened inside the mounting sleeve 5, a guide ring 8 opened at the end of the mounting sleeve 5 away from the electrode 6, and the guide ring 8 and the return groove 7 communicating with each other, a plurality of return holes 9 equidistantly opened at the end of the mounting sleeve 5 away from the electrode 6, and a connecting seat 10 mounted at the end of the mounting sleeve 5 away from the electrode 6.

[0023] Specifically, the connection end of the mounting sleeve 5 and the connecting seat 10 is provided with a sealing ring, which can increase the sealing during device assembly.

[0024] Specifically, the connection end between the nozzle 4 and the mounting sleeve 5 is provided with a sealing ring 17, which further improves the connection fit between the nozzle 4 and the mounting sleeve 5.

[0025] Specifically, the cooling mechanism also includes a guide groove 11 formed inside the connecting seat 10, which communicates with the return hole 9. A return pipe 12 is installed at the top of the connecting seat 10, and one end of the return pipe 12 extends into the interior of the guide groove 11. A water inlet pipe 13 is provided below the return pipe 12. A plug-in seat 14 is fixedly installed at one end of the water inlet pipe 13, and a guide pipe 15 is fixedly installed at one end of the plug-in seat 14 through the side wall of the connecting seat 10. The end of the plug-in seat 14 is threadedly connected to the end of the mounting sleeve 5. The guide pipe 15 is located inside the mounting sleeve 5, and a water outlet pipe 16 is inserted at the end of the guide pipe 15 away from the plug-in seat 14.

[0026] Specifically, the end of the mounting sleeve 5 near the nozzle 4 is provided with a mounting bracket that is installed and fitted with the guide tube 15, and the mounting bracket is provided with a flow hole in an annular shape.

[0027] Specifically, the bottom end of the connector 10 is threaded with a sealing bolt, which can be used to clean the guide groove 11 inside the connector 10.

[0028] Specifically, the end of the water outlet pipe 16 near the guide pipe 15 is provided with an inclined groove that is inserted into the guide pipe 15, thereby increasing the degree of insertion between the guide pipe 15 and the water outlet pipe 16.

[0029] In this embodiment, to increase the ease of assembly and disassembly of the device, reference is made to... Figures 1 to 4The specific implementation method is as follows: After the nozzle 4 and electrode 6 have been working for a long time, the temperature of electrode 6 continues to rise. If electrode 6 is in an overheated state for a long time, it will not only affect the normal operating efficiency of electrode 6, but also shorten the service life of electrode 6, and even cause equipment failure. Therefore, it is necessary to cool electrode 6 in a timely and effective manner. In order to quickly and accurately deliver cooling water to electrode 6, the device is equipped with a cooling mechanism for directional delivery of cooling water to ensure that cooling water reaches the position of electrode 6 efficiently and quickly reduces the temperature of electrode 6.

[0030] It should be noted that when cooling of electrode 6 is required, the cooling system will be activated: external cooling water is first precisely introduced into the device through inlet pipe 13. With the stable connection between inlet pipe 13 and connector 14, the cooling water is directionally delivered to the guide pipe 15, and then directly guided to the critical heat-generating area of ​​electrode 6 through outlet pipe 16. This allows the cooling water to quickly envelop electrode 6, achieving immediate heat transfer. This not only rapidly reduces the operating temperature of electrode 6, preventing performance degradation or material loss due to high temperatures, but also ensures that electrode 6 remains within a stable operating range, effectively extending its service life and guaranteeing subsequent processing. The precision and stability of processes such as reaction are ensured. After the cooling task is completed, the cooling water will enter the preset return channel of the device: the return groove 7 formed between the installation sleeve 5 and the guide pipe 15 can efficiently collect the used cooling water. The guide ring 8 at the end of the return groove 7 has a buffering effect, which allows the cooling water to stay briefly. On the one hand, it can further absorb residual heat and improve the cooling utilization rate. On the other hand, it can slow down the water flow speed and prevent pipe wear caused by water flow impact. Subsequently, the cooling water is smoothly transported through the return hole 9 to the guide groove 11 inside the connecting seat 10, and finally recovered through the return pipe 12 fixedly installed on the connecting seat 10.

[0031] It should also be noted that the cooling mechanism adopts a modular design, coupled with a linear arrangement scheme, forming an efficient and flexible structural system. The modular design breaks down the core functions of the cooling system into independent modules, each of which can be flexibly combined or maintained individually according to actual needs. At the same time, the linear arrangement allows each module to be arranged in an orderly manner along a preset straight line, avoiding the problems of pipe intersections and structural redundancy in traditional distributed designs. This significantly reduces the space occupied by the cooling mechanism inside the equipment, not only reserving more installation and operating space for other core components, but also optimizing the overall layout of the equipment, making the internal structure simpler and more regular, and reducing space interference during later maintenance. In the installation process, the advantages of modularity and linear design are particularly prominent: on the one hand, modular disassembly allows each component to be transported and installed one by one without the need to transport the entire heavy structure, reducing manpower and equipment costs during installation, and reducing installation errors caused by oversized components; on the other hand, the linear arrangement forms a clear installation baseline, and the staff only needs to connect each module in sequence along the straight line, without repeatedly adjusting the angle and position, greatly simplifying the installation process and improving installation efficiency.
