Description

Technical Field

[0001] The utility model relates to the technical field of stretched component processing, in particular to a stretched component rotary cutting die. Background Art

[0002] Mold processing refers to the processing of forming and blanking tools. It also includes shearing dies and die-cutting dies. Usually, the mold consists of an upper mold and a lower mold. The steel plate is placed between the upper and lower molds. The material is formed under the action of a press. When the press is opened, a workpiece determined by the mold shape is obtained or the corresponding waste is removed. Workpieces as small as electronic connectors and as large as car dashboards can be formed by molds.

[0003] Among them, the drawn parts are processed by stamping dies. The stamping die is a special process equipment that processes materials into parts in the cold stamping process. It is called a cold stamping die. After the metal sheet is stamped, a drawn part and an outer edge to be cut will be formed. The drawn part and the outer edge are connected together and need to be cut. However, when the outer contour of the drawn part is relatively complex, it cannot be done by simple cutting.
