Description

Novel right angle molding rebound correction structure for arc-shaped surface Technical Field The utility model belongs to the field of stamping correction forming, and particularly relates to a novel right-angle forming rebound correction structure for an arc-shaped surface. Background In conventional stamping production, the calibration process is a critical step to ensure that the dimensional accuracy and shape of the part meet design requirements. The traditional correction mode is usually integrated correction of the inserted punch face, namely, the punch is directly inserted into a die to integrally correct the part, and the correction work can be rapidly completed under the condition of low precision requirements on the part. However, when the product structure is complex and the tolerance is required to be precise, when the punch surface is directly inserted into the correction, the right-angle surface of the product is easily scratched and damaged due to different stress forms, and the right-angle part is distorted and deformed, so that the effect of correction molding cannot be achieved.
