Chain plate, stamping die, and chain plate manufacturing method capable of reducing deformation of the edges of a plurality of chain plates during a stamping process and increasing the strength of the plurality of chain plates

A chain plate, a stamping die, and a chain plate manufacturing method are provided, and the chain plate manufacturing method uses the stamping die to stamp a plurality of chain plates on a steel belt, the plurality of chain plates are divided into a plurality of forge-cut chain plates and a plurality of punch-cut chain plates, each chain plate includes a contoured peripheral surface, and at least a part of the contoured peripheral surface has an initial forging surface part and a cutting surface part having a smooth cutting surface. The chain plate manufacturing method includes a feeding step, a hole-punching step, an initial forging step, and a cutting step. The hole-punching step punches out at least two sets of paired-perforations on the steel belt. In the initial forging step, the initial forging surface part is formed by forging at the at least one set of perforations. The cutting step punches out and forms the punch-cut chain plate between two adjacent initial forging surface parts, and punches out and
