Description

Cover plate stamping die [ Field of technology ] The invention relates to the field of stamping dies, in particular to a cover plate stamping die. [ Background Art ] The stamping die is an important processing tool in the current industrial production, when the automobile circuit board cover plate is subjected to punching processing in advance, the temperature of a knife edge rises due to long-time punching, aluminum is adhered when the knife edge is subjected to punching at high temperature, the original cooling mode is to blow air to the knife edge, however, aluminum scraps can be splashed on a processing workpiece and cause indentation when the knife edge is subjected to punching, in addition, when the size of an inner cavity of the processing workpiece changes, the gap between the processing workpiece and a lower module is large or cannot be enlarged, the lower module positioning part is not provided with an elastic fixing mode, and meanwhile, the lower module is in a whole form, so that the replacement is not facilitated. Therefore, there is a need for improvements over the prior art. [ Invention ] The invention aims to solve the technical problems that a high Wen Daokou cooling mode and a lower module positioning part are not provided with an elastic fixing mode, and the lower module is in a whole form, so that the replacement is not facilitated.
