Description

Stamping die structure and stamping die Technical Field The invention relates to the technical field of stamping dies, in particular to a stamping die structure and a stamping die. Background The stamping die is used for separating or plastically deforming materials such as pipes, plates and the like by applying pressure to the materials so as to obtain workpieces with the size and shape required by users. The stamping workpiece is widely applied to products in various industries such as automobiles, instruments and meters, office equipment, household appliances and the like, so that the workpiece (such as petal-shaped and lotus-shaped workpiece) which is complex in stamping shape and needs to be bent at multiple positions inside and outside is inevitably required in the industry.
