Description

Technical Field

[0001] This utility model belongs to the field of welding equipment technology, and relates to an argon arc welding torch device, more specifically, to an argon arc welding torch device using a novel polytetrafluoroethylene gas pipe. Background Technology

[0002] Currently, most TIG welding torches on the market use rubber shielding gas delivery lines. However, this design is prone to aging and cracking during long-term use due to high temperatures, mechanical friction, or chemical corrosion. Aged rubber tubing loses its necessary flexibility and is prone to rupture during frequent equipment movement or welding along complex paths, leading to argon gas leakage and creating safety hazards.

[0003] Furthermore, as rubber hoses age, they may decompose, contaminating the purity of the welding shielding gas and consequently affecting the quality of the welding operation. Therefore, frequent hose replacements not only increase production costs but also maintenance costs.

[0004] While some patents employ metal air tubes to address this issue, these tubes are often heavy and lack flexibility. Other patents attempt to reduce tube wear by uniformly moving the adjustment device, but this method does not fundamentally solve the limitations of material properties. In terms of adaptability, these designs still have room for improvement and have low levels of automation.

[0005] To address this issue, an argon arc welding torch device was designed to overcome the aforementioned problems. Utility Model Content

[0008] Preferably, the first gas guide tube is a single piece made of polytetrafluoroethylene (PTFE), and the second gas guide tube consists of two separate sections. One section is used to connect the control valve and the welding torch. This section is made of a common material or PTFE. The other section is used to connect the control valve and the second gas valve of the power supply device. This section is made of PTFE to improve the service life of the entire pipeline.

[0009] Preferably, sealing devices are provided at the connections between the gas cylinder flow control valve, the first gas valve and the first gas guide pipe, and the second gas valve, the control valve, the welding torch and the second gas guide pipe to improve the overall airtightness.

[0010] Preferably, the control valve is a solenoid valve or a butt-welded ball valve.

[0011] Preferably, pressure monitors are installed on the first and second gas guide tubes to ensure the safety of the welding torch during use and to prevent gas leakage and blockage.

[0012] Preferably, the sealing device is a rubber sealing ring, a mating thread, or a combination of a rubber sealing ring and a thread.

[0013] Preferably, the welding torch head is provided with a guide fluid, and the slot spacing and number of openings are adapted to the dimensions of the aluminum alloy welded structure.

[0019] The present invention will now be described in detail with reference to the accompanying drawings: Figure 1 As shown, an argon arc welding torch device includes an argon arc welding torch device body, which consists of an argon cylinder 1, a power supply device 2, a control valve 3, and a welding torch 4. The top of the argon cylinder 1 is provided with a cylinder flow control valve 5. The cylinder flow control valve 5 is connected to the first gas valve 6 of the power supply device 2, and the second gas valve 7 of the power supply device 2 (welding power supply) is connected to the welding torch 4 through a first gas guide pipe 8 and a second gas guide pipe 9, respectively. A control valve 3 is provided on the second gas guide pipe 9 to control the opening or closing of the argon gas channel of the entire pipeline, thereby controlling the opening or closing of the welding torch 4.

[0020] The first gas guide tube 8 is a single piece made of polytetrafluoroethylene (PTFE). The second gas guide tube 9 consists of two separate sections. One section, 11, is used to connect the control valve 3 and the welding torch 4. This section is made of a common material or PTFE. The other section, 12, is used to connect the control valve 3 and the second gas valve 7 of the power supply device 2. This section is made of PTFE to improve the service life of the entire pipeline.

[0021] Sealing devices 13 are provided at the connections between the gas cylinder flow control valve 5, the first gas valve 6 and the first gas guide pipe 8, as well as between the second gas valve 7, the control valve 3, the welding torch 4 and the second gas guide pipe 9, to improve the overall airtightness.

[0022] The control valve 3 is a solenoid valve or a welding ball valve. Pressure monitors 10 are installed on the first air guide pipe 8 and the second air guide pipe 9 to ensure the safety of the welding torch 4 during use and to prevent air leakage and blockage. The sealing device 13 is a rubber sealing ring, a mating thread, or a combination of a sealing ring and a thread, ensuring the overall airtightness of the connection. A guide fluid (not shown in the figure) is provided in the torch head of the welding torch 4, and its slot spacing and number of openings are adapted to the dimensions of the aluminum alloy welding structure.

[0023] The argon arc welding torch device designed in this utility model can effectively detect gas leakage caused by deformation and cracking of the gas guide tube due to long-term use through a designed pressure monitor, and can replace and maintain it in a timely manner. In addition, the gas guide tube is made of polytetrafluoroethylene material, which is more durable and corrosion resistant than conventional gas guide tubes, and has a lower cost of use compared to metal gas guide tubes.

[0024] This invention features sealing devices in each connecting pipeline to improve overall airtightness and reduce air leakage at the connection points. Control valves are also provided at the welding torch and gas cylinder positions to adjust the opening, closing, and degree of opening, facilitating operation and thereby improving welding quality, welding torch durability, and safety.

[0025] The gas guide tube of this invention is made of polytetrafluoroethylene (PTFE), which possesses a series of excellent properties. Firstly, its high-temperature resistance is significantly superior to rubber materials, enabling it to operate stably for extended periods in high-temperature environments without rapid aging, deformation, or damage due to high temperatures, ensuring a stable supply of protective gas during welding. Secondly, PTFE exhibits excellent chemical corrosion resistance, effectively resisting the erosion of various chemicals. Even in chemically contaminated working environments, it maintains the integrity and functionality of the gas tube. Furthermore, PTFE possesses excellent flexibility and durability, resisting fatigue fracture even under frequent bending, significantly extending the service life of the gas tube.

[0026] This invention improves the stability and reliability of the welding torch device, ensures a stable supply of shielding gas, and thus enhances welding quality. To ensure normal operation, a bypass pipe with a manually controlled valve, connecting the first gas valve of the power supply device to the gas cylinder, can be installed on one side of the first gas pipe. The bypass pipe can better ensure that the power supply device and the second gas pipe always store shielding gas (argon).

[0027] The working principle of this utility model is as follows: In practical applications, the welding torch device of this invention is installed on a welding workbench. First, ensure that both ends of the PTFE gas tube are tightly connected to the inlet of the shielding gas source (gas cylinder) and the power supply, respectively. Use a special threaded connection and sealing gaskets to ensure a tight seal at the connection point and prevent leakage. Next, precisely control the flow rate of the welding shielding gas using the gas cylinder flow control valve. Finally, connect the welding torch to the power supply to complete the assembly of the entire device.

[0028] The specific embodiments described herein are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
