Nowadays, the stamping process has become one of the commonly used techniques in metal processing, which is achieved through processing methods with high productivity and low material consumption.For the production of large quantities of parts and components, compared with other metal processing and forming technologies, it can effectively save more money, time and labor, and facilitate the implementation of mechanized and automated production modes.For instance, in the field of automobile industry, the proposal of lightweight can effectively solve the problems of environmental pollution and energy crisis.Therefore, high-strength steel plate, as a typical lightweight material, has been widely used in the automobile manufacturing industry.However, with the improvement of the tensile strength of high-strength steel, its plastic properties are greatly reduced.During the cold stamping process, the sheet will have cracks, wrinkles, corrosion, orange peel and other forming defects, which will reduce the forming accuracy of the sheet.Over time, it will limit the use of high-strength steel in the car body.On the other hand, hot forming technology is widely used in automotive engineering due to its advantages of good forming performance, small forming load, small springback, and high strength of parts after quenching.Therefore, it is one of the most significant methods that stamping high-strength steel as components in various engineering fields. However, it is inevitable that the stamped parts will have forming quality defects in the process of hot stamping. For this reason, this paperstudies the defect analysis and presents quality control measures of high-strength steel stamping.
