Description

Technical Field

[0001] The utility model relates to the technical field of household appliance metal component processing, in particular to a welding device for household appliance metal component processing. Background Art

[0002] Metal components are parts made of metal materials and are widely used in many fields such as machinery, electronics, construction, and transportation. They are usually made of metal pipes, metal plates, metal rods, metal wires, etc., and have good mechanical properties, corrosion resistance, thermal stability, electromagnetic shielding, and tensile strength. In the field of electronics, metal electronic components refer to electronic parts that contain metal materials inside. Home appliance metal components refer to metal parts and components used in home appliances. In the production process of home appliance metal components, cutting, bending, drilling and punching, welding, surface treatment, and component assembly can be performed.

[0003] Common welding devices for processing metal components of household appliances are usually composed of structures such as welding power supply, welding gun or welding torch, transmission, control system and cooling system. First, align the welding surfaces of two groups of metal components of household appliances and fix them, then transmit power to the welding structure to generate heat, and contact the welding structure with the welding surface of the metal component. The welding surfaces between the metal components of household appliances are melted and connected together. This is the common structure and use of welding devices for processing metal components of household appliances. Traditional welding devices for processing metal components of household appliances connect two groups of metal pipes and weld them on the workbench, which can easily lead to uneven welding at the connection of the metal pipes and easy deviation, resulting in reduced processing quality or even failure of the welded metal workpiece. Some welding devices for processing metal components of household appliances use two sets of racks to drive the corresponding metal components to translate toward each other, so that the two groups of metal components are connected to avoid deviation. However, in this method, since the metal components of household appliances need to be welded all around the welding point, and the device has a single function and cannot adjust the welding surface of the metal components of household appliances, the welding operation of the metal components of household appliances is complicated and inconvenient to use. Therefore, a welding device for processing metal components of household appliances is proposed. Utility Model Content
