What are the surface quality requirements of cover parts in automobile stamping parts?

Covering parts in automobile stamping parts require smooth surfaces and clear ridges, and no quality defects such as wrinkles, indentations, scratches, burrs, bumps and depressions, and other damage to the perfect surface are not allowed. At the same time, the surface of the covering parts in the relevant automobile stamping parts must also have good coordination, uniform transition, and smooth matching of the ridgeline joints, so that the automobile body looks consistent and beautiful in appearance. Therefore, only by carefully analyzing, judging and studying the surface quality defects can we formulate corresponding rectification measures. Before judging the surface quality defects, we must first understand the division of the inspection area of u200bu200bthe covering parts in the automobile stamping parts. These divisions are applicable For painting, sheet metal and other parts. As shown in the figure, the inspection area of u200bu200bcover parts in automobile stamping parts can be divided into four areas, namely I II III IV area. The specific area is shown in the table; any covering parts must not have obvious defects that anyone can see, there must be no leaking holes, rust, etc., and no obvious oil patterns are allowed in the I II area; article recommendation: sheet metal What are the characteristics and uses of stamping parts?
