TECHNICAL FIELD
[0001] The present application relates to the technical field of welding, in particular to an argon arc welding cutting all-in-one machine. BACKGROUND
[0002] In the metal processing industry, argon arc welding and plasma arc cutting are two types of high-frequency combined processes. Argon arc welding process is based on the principle of ordinary electric arc welding, using argon to protect the metal welding material, and through high current to make the welding material melt into liquid on the welded base material to form a molten pool, so that the welded metal and the welding material achieve metallurgical bonding. Since argon is continuously supplied during high-temperature melting welding, the welding material cannot come into contact with oxygen in the air, thereby preventing the oxidation of the welding material, so stainless steel, iron hardware and other metals can be welded. Plasma arc cutting is a process in which mixed gas is passed through a high-frequency electric arc (the gas can be air, hydrogen, argon, and nitrogen mixture). The high-frequency electric arc makes some gas "decompose" or ionize into basic atomic particles, thereby generating "plasma", and then the electric arc jumps to the stainless steel workpiece. The high-pressure gas blows the plasma out of the torch nozzle, and the high energy released when the various gases in the plasma return to normal state produces a high temperature of 2700°C, which is almost twice the melting point of stainless steel, thereby rapidly melting the stainless steel. The melted metal is blown away by the high-pressure gas stream. Argon arc welding has the advantages of high welding quality, effective prevention of workpiece oxidation, and is the preferred process for thin plate and non-ferrous metal welding. Plasma arc cutting has the advantages of good cutting quality, small heat-affected zone, and can cut various conductive metals, and plays an important role in processes such as blanking, trimming and hole cutting. In actual workpiece processing, there are cases where a workpiece needs to complete argon arc welding or surfacing and plasma arc cutting at the same time. The common method on the market is to use argon arc welding machine and plasma arc cutting machine respectively to complete argon arc welding process and plasma arc cutting process. There are deficiencies in sequentially separating argon arc welding process and plasma arc cutting process on the same workpiece on two machines. Workpiece handling, clamping and alignment between different machines consume a lot of time; in separate operation, it is difficult to ensure the uniformity of the reference during two-time clamping of the workpiece, positioning errors and cumulative errors are easy to occur, affecting the processing precision; the production efficiency is low, and the equipment investment and land cost are high. Patent No. CN218638864U discloses an argon arc welding and cutting all-in-one machine, which comprises a welding and cutting all-in-one machine shell, an argon arc welding module is arranged in the welding and cutting all-in-one machine shell, and a plasma cutting module is also arranged in the welding and cutting all-in-one machine shell; a gas input assembly is arranged on the side wall of the welding and cutting all-in-one machine shell, the gas input assembly comprises a communication pipeline arranged on the gas inlet of the welding and cutting all-in-one machine shell; a three-way valve is arranged at the end of the communication pipeline, one end of the three-way valve is provided with a gas conveying pipeline a, and the other end of the three-way valve is provided with a gas conveying pipeline b; a closed cover plate is sleeved on the outer sides of the gas conveying pipeline a and the gas conveying pipeline b, a through hole plate is arranged on the side wall of the closed cover plate; two through holes are formed in the side wall of the through hole plate, an inner groove block is arranged in one of the through holes, and a polystyrene ball is arranged in the inner groove block. The argon arc welding and cutting all-in-one machine will rise when receiving gas, and the polystyrene ball is used to determine whether the gas leaks, thereby reducing unnecessary losses.The patent sets the argon arc welding module and the plasma cutting module inside the welding and cutting integrated machine shell, thereby forming a welding and cutting integrated machine, which can perform welding and cutting operations in one device. However, there are some deficiencies: the welding head 4 and the cutting head 5 are simply marked on the welding and cutting integrated machine shell 1, and the positions of the welding head 4 and the cutting head 5 are one above the other. It is not clear whether the welding head 4 and the cutting head 5 are in a sequential working mode or a simultaneous working mode. It is also not clear whether the welding head 4 will be affected when the upper cutting head 5 is working, because molten debris will fall during the cutting process of the cutting head 5. The welding head 4 and the cutting head 5 are fixed in the figure and the specification, and cannot be moved. Therefore, the fixed welding head 4 and the cutting head 5 cannot complete the complete process of argon arc welding and the complete process of plasma cutting in practice (both the welding gun and the cutting gun need to be continuously moved manually or automatically to complete the argon arc welding process and the plasma cutting process in actual production).
