Abstract:
A method for manufacturing a mechanical part by hot stamping, and a mold and a system thereof. The method includes: heating a steel plate blank at a predetermined heating temperature; and placing the steel plate blank into a mold of the mechanical part, and stamping the steel plate blank to form wrinkles at a rounded corner of the mold and form the mechanical part in the mold: wherein, the mold of the mechanical part includes a female mold and a male mold, a stamping gap configured to accommodate the steel plate blank is provided between the female mold and the male mold, and a width of the stamping gap at the rounded corner of the mold is larger than a thickness of the wrinkles.
