Today, the editor will introduce the latest model suitable for welding electrical switches, small hardware, and fine workpieces: precision spot welding machine!
The precision welding power supply of precision spot welding machine has become a highly competitive processing method in the precision machining industry due to its high strength of welding points, small heat affected zone, and no need for other welding materials. It has the advantages of high efficiency, good consistency, high yield rate, and simple operation, with a welding qualification rate of over 99.99%. Under high-speed welding conditions, the electrode service life is 5-7 times that of traditional welding machines, and the energy-saving effect is significant. The power consumption is 40% of that of traditional welding machines. This welding power supply has multiple interfaces, making it extremely convenient to interface with various automation equipment. It has an LCD operation interface, which is very simple and intuitive to operate. It has monitoring functions such as welding current, welding voltage, and welding power.
The advantages of precision spot welding machines are as follows:
1. The direct pressure mechanism adopts a new structure for the guiding part, with high follow-up performance.
2. High strength body structure, good rigidity, can prevent electrode tip sliding during pressurization.
3. Structure, beautiful and elegant, especially suitable for fine workpiece welding and assembly line installation production.
4. A safe and high-performance pneumatic system with adjustable pressurization speed.
5. Water saving circulating water cooling system, equipped with quick water cooling joints, facilitates the replacement of water-cooled electrodes or fixtures.
Therefore, precision spot welding machines are suitable for welding power lithium-ion battery modules, 3C lithium-ion battery packs, nickel hydrogen battery packs, hardware components, electronic and electrical parts, wire terminals, stainless steel parts, metal jewelry, copper products, aluminum products, etc.
So how should precision spot welding machines be maintained on a daily basis?
Due to the fact that the contact area of the electrode determines the current density, the electrical resistivity and thermal conductivity of the electrode material are related to the generation and dissipation of heat. Therefore, the shape and material of the electrode have a significant impact on the formation of fusion nuclei. With the deformation and wear of the electrode end of the precision spot welding machine, the contact area increases, and the strength of the solder joint will decrease.
The oxides, dirt, oil, and other impurities on the surface of the workpiece used in precision spot welding machines increase the contact resistance. Excessive oxide can even prevent current from passing through. Local conduction, due to excessive current density, can result in splashing and surface burning. Therefore, thoroughly cleaning the surface of the workpiece is a necessary condition to ensure obtaining high-quality joints.
Spot welding is a resistance welding method in which a welded joint is assembled and pressed between two electrodes, and the base metal is melted using resistance heat to form a welding point.
Precision spot welding machine welding transformer is a spot welding electrical device, and its secondary only has one loop circuit. The upper and lower electrodes and electrode arms are used for both conducting welding current and transmitting power. The cooling water circuit passes through parts such as transformers and electrodes to prevent heating. When welding, the cooling water should be supplied first, and then the power switch should be turned on. The quality of electrodes directly affects the welding process, welding quality, and productivity.
The electrode materials for precision spot welding machines are commonly made of copper, chromium zirconium copper, etc; There are various shapes of electrodes, mainly determined by the shape of the welded component. When installing electrodes in precision spot welding machines, attention should be paid to keeping the upper and lower electrode surfaces parallel; The electrode surface should be kept clean and often trimmed with sandpaper or file.
