Description

Technical Field

[0001] The invention relates to the technical field of plasma welding equipment, in particular to easy-to-maintain plasma welding equipment. Background Art

[0002] With the advancement of science and technology and the development of industry, the requirements for welding technology and equipment are getting higher and higher. Plasma welding equipment, with its high efficiency, precision and innovation, can meet the needs of modern industry for high-quality and high-efficiency welding. For example, some special instruments and implants in the medical industry need to be manufactured using high-precision and high-cleanliness welding technology. In the automotive manufacturing industry, plasma welding technology is widely used in the welding of body structures, the manufacture of parts and the repair of engine parts. Its high efficiency and precision make the production process more automated and efficient, improve production efficiency and product quality, and make plasma welding equipment play an important role in modern industry.

[0003] Plasma welding equipment in the prior art generally consists of a welding power supply, a welding gun, a gas supply system, a water system, a control system, etc. When in use, the plasma welder provides direct current or alternating current through an external power supply. After the current enters the welder, it will be rectified, filtered, and other processes through electronic components, and then sent to the welding gun head. An arc will be generated between the electrodes of the welding gun head, and a plasma arc will gradually form as the contact area increases. In the arc, the high temperature and high energy current excite the gas or steam molecules to ionize them to form plasma. When the plasma arc contacts the metal workpiece, its high temperature causes the metal to melt rapidly and form a molten pool. At the same time, the plasma welder also prevents the molten pool from being contaminated by oxygen in the air by feeding a protective gas, such as argon or carbon dioxide, during the welding process, and can effectively prevent oxidation and the formation of other impurities to ensure the quality of the weld.

[0004] However, in actual use, in order to avoid sudden failures of the equipment during operation and to ensure the continuity and stability of the welding work, the plasma welding equipment is generally inspected daily, and the installation of the side wall of the welding machine is disassembled to check the internal power supply and gas supply system. Since the mounting plate is installed on the welding machine with bolts, specific tools are required to remove the bolts during disassembly. In order to ensure the installation stability of the mounting plate, multiple bolts are generally used for installation. During disassembly, multiple bolts need to be removed one by one, making the disassembly process of the mounting plate relatively cumbersome, thereby increasing the time cost of maintenance. Once an emergency occurs, this inefficient maintenance method will lead to production delays or extended equipment downtime, thereby reducing the economic efficiency of use. Summary of the invention
