一种制造机械零件的方法、模具和系统
摘要：
本发明公开了一种制造机械零件的方法、模具和系统，采用热冲压工艺制造机械零件，所述方法包括：在预设的加热温度下加热坯料钢板；将所述坯料钢板放入所述机械零件的模具冲压，以便所述坯料钢板在所述模具的圆角处形成褶皱和在所述模具中形成所述机械零件；所述机械零件的模具包括凹模和凸模，所述凹模和凸模之间具有容纳所述坯料钢板的冲压空隙，所述模具的圆角处的冲压空隙宽度大于所述褶皱的厚度。通过本发明的技术方案，可以防止由于褶皱不规则堆积而造成钢板继续冲压时在褶皱处被拉裂，从而可以减少生产中被拉裂的产品数量，从而可以降低产品的废品率，进而降低生产成本，节省对钢铁资源的消耗。
摘要（英）：

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.
