The invention discloses a stamping part production process. The stamping part production process comprises the following steps that (1) separation is carried out, specifically, blanking is carried outfirstly, stamping is carried out through a stamping die along a closed curve, the portion stamped off is a part which is used for manufacturing flat plate parts in various shapes, stamping is carriedout through the stamping die along the closed curve, the portion stamped off is scraps, then trimming is carried out, the edge of the formed part is trimmed to be regular or to be in a certain shape,and stamping is carried out through the stamping die along a non-closed curve to generate separation; and (2) molding is carried out, specifically, a plate blank is made into various opening hollow parts, the edge of a plate or a semi-finished product is made to be vertical along a certain curve at certain curvature, and the size precision of the molded part is improved or small corner radius isobtained in a shaping mode. Various measures are taken for defects, the quality of stamping parts is ensured, and the problem that due to the defects of cracking, stacking, waving, galling, deformation, burrs, material lack, unqualified size and the like of stamping parts produced by an existing stamping technology, the quality of the stamping parts is affected is solved.
