Studies on the Technology of the Fine Blanking without Gear Ring of Steel Back Plate with Mechanics Properties and Material Properties

Abstract:

The steel back plate is one of the important parts of automotive friction brake block, and the current production technology is conventional blanking technology, which obtains only a low percentage of bright surface. The fine blanking without gear ring technology makes the steel back get a higher percentage of the bright surface. Based on finite element simulation, the effects of different outlines and different process parameters on the percentage of bright surface during fine blanking without gear ring of steel back plate were investigated in this paper. According to the results, the best process parameter in every single factor was obtained, which offers guide for the technology of the fine blanking without gear ring of steel back plate.
