Description

Technical Field

[0001] The utility model relates to the technical field of radiator production, in particular to a spot welding device for producing large radiators. Background Art

[0002] As we all know, a radiator is a device that transfers part of the heat of a hot fluid to a cold fluid. Large electronic radiators are usually made of aluminum alloy extrusion to form profiles, and then machined and surface treated. This material has good thermal conductivity and corrosion resistance. Large electronic radiators need to be welded during the machining process. The current welding device for radiator production is usually a spot welder. During spot welding, pressure is first applied to make the workpieces in close contact, and then current is turned on. The contact point of the workpieces melts under the action of resistance heat, and a weld is formed after cooling.

[0003] However, the current spot welding devices for large radiator production usually rely on manual support of the workpiece when positioning the workpiece. Since the surface of the heat sink is relatively smooth, manual support can easily cause uneven contact between the workpieces, resulting in inaccurate welding positions, affecting product quality. At the same time, a large amount of sparks will be generated during the spot welding process. The sparks fly everywhere and have a great impact on the workers' clothes and skin, causing inconvenience in use. Therefore, a spot welding device for large radiator production is proposed to solve the above-mentioned problems. Utility Model Content
