Description

Convex hull product processing method and device Technical Field The invention belongs to the technical field of stamping processing, and particularly relates to a convex hull product processing method and device. Background The box body and the backboard of electronic products such as new energy, household appliances and the like are largely made of metal flat stamping parts, the metal flat stamping parts are typical sheet stamping forming and comprise a plurality of local forming characteristics, the distribution of the local forming characteristics is quite uneven, if a traditional several-punch cutting process is used, the convex hull is firstly formed and then cut edge is cut, so that the edge convex hull can be flattened, secondary adjustment is needed, one-time forming cannot be carried out, and the product development and manufacturing cycle is prolonged. If the convex hull is firstly cut and then formed, the convex hull can be prevented from being flattened, but meanwhile, for large-sized flat plate type stamping parts with complex structures, the method can cause uneven stress distribution at the convex hull at the edge of the product due to uneven convex hull and other characteristic distribution, so that the problems of deformation and poor flatness are caused, and the defects of the product seriously affect the product quality and assembly precision of the parts. Aiming at the problems of bulging, warping, rebound and twisting of parts after stamping of the local characteristic thin plates, the common solution in the prior industry is to optimally design an actual die and continuously modify, test mistakes and adjust the actual die, so that a large amount of die test time is required, and a machine is occupied for a long time, thereby causing resource waste. Therefore, how to develop a process method for realizing one-step processing and forming while ensuring the quality of products is a technical problem which needs to be solved by the technicians in the field.
