The invention discloses a stamping die with a rotary scrap cutter and a stamping method thereof. The stamping die comprises an upper die base, an upper die edge-trimming cutter block, an upper die pressing material, a lower die edge-trimming cutter block and a lower die base. The stamping die further comprises a scrap cutter assembly which is composed of an upper die rotating scrap cutter, a lowerdie scrap cutter, an impact block and a buffer spring, wherein the scrap cutter assembly is arranged between the upper die base and the lower die base. The stamping method comprises the steps of a preparation stage, a first shearing section, a second shearing section and a stamping end section. The rotary scrap cutter is used on the die for cold stamping an outer covering part and an aluminum plate, because the scrap cutter and the edge-trimming cutter have no offset in the edge trimming process of the product, the trimming line of a product does not generate burrs, the whole-circle edge trimming can be completed in one process, the stamping process is reduced, and the cost is saved.
Description
technical field [0001] The invention relates to the field of punching dies, in particular to a punching die with a rotating waste knife and a punching method thereof. Background technique [0002] For the edge trimming mold of the cold stamping outer cover and aluminum plate, scrap knives are generally not used for product quality, so it is impossible to complete the full peripheral edge trimming in one process. It may be necessary to increase the stamping process to solve the product edge trimming problem, making it costly. [0003] For the workpiece processed by the stamping die using a general waste knife, chips and burrs are often produced, and the generated chips will be brought into the mold, causing quality problems such as crushing and protrusions on the appearance of the part, and even damage the mold blade; The generation of burr will generate additional trimming process, resulting in an increase in process and cost. Contents of the invention [0004] In order t...
