下模

The lower die is the stationary component in a die set that shapes materials during stamping, forging, or pressing operations.

技术定义与适配语境
典型 下模 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

In industrial manufacturing, the lower die is the fixed half of a die set mounted on the press bed or bolster plate. It contains cavities, cutting edges, or forming surfaces that work in conjunction with the upper die to perform operations such as blanking, piercing, bending, drawing, or coining on sheet metal, plastics, or other materials. The lower die provides precise alignment through guide pins or bushings and often includes features for material feeding, part ejection, and scrap removal.

定义
In industrial manufacturing, the lower die is the fixed half of a die set mounted on the press bed or bolster plate. It contains cavities, cutting edges, or forming surfaces that work in conjunction with the upper die to perform operations such as blanking, piercing, bending, drawing, or coining on sheet metal, plastics, or other materials. The lower die provides precise alignment through guide pins or bushings and often includes features for material feeding, part ejection, and scrap removal.
工作原理
The lower die remains stationary while the upper die descends under press force. Material placed between them is shaped through mechanical deformation, shearing, or compression. The die's geometry determines the final part shape, with clearance between upper and lower cutting edges ensuring clean separation in shearing operations.

常见问题

What is the difference between lower die and upper die?

The lower die is stationary and mounted on the press bed, while the upper die moves with the press ram. The lower die typically contains die cavities and cutting edges, while the upper die carries punches and forming tools.

How often should lower dies be maintained?

Lower dies require regular inspection every 10,000-50,000 cycles depending on material hardness and production conditions. Maintenance includes cleaning, sharpening cutting edges, checking alignment, and replacing worn components.
