大发体育Cold-working sheet metal parts have the characteristics of light weight, high strength and simple processing, so they are widely used. But in the process of processing, cold-working sheet metal should reduce welding as much as possible. What is this? Cold sheet metal processing, as the name suggests, does not require heat treatment, and welding is heat processing.
Cold-working sheet metal material will cause deformation after welding, not only the welding surface treatment is not beautiful, but also affects the production efficiency, so can be changed by processing technology to replace welding, such as stamping.
大发体育The workpiece stamped out of the sheet metal is not only beautiful, but also difficult to deform, but it needs to make simple dies.
In addition, indirect break welding can be used instead of continuous welding for welds with less stress or only linking effect, or riveting can be used instead of welding, which is time-saving and beautiful.
