下模座

Lower die block is the stationary base component in a V-die set that supports and aligns the die during sheet metal bending operations.

技术定义与适配语境
典型 下模座 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。

The lower die block is a precision-machined component in a V-die set that serves as the foundation for bending operations. It provides a stable, rigid platform that supports the die insert and maintains alignment with the upper punch during the bending cycle. Typically mounted to the press bed, it features precisely machined surfaces, mounting holes, and alignment features to ensure accurate part formation and repeatability in industrial metal fabrication processes.

定义
The lower die block is a precision-machined component in a V-die set that serves as the foundation for bending operations. It provides a stable, rigid platform that supports the die insert and maintains alignment with the upper punch during the bending cycle. Typically mounted to the press bed, it features precisely machined surfaces, mounting holes, and alignment features to ensure accurate part formation and repeatability in industrial metal fabrication processes.
工作原理
The lower die block operates on the principle of providing a fixed, rigid reaction surface against which sheet metal is formed. When the upper punch descends, it forces the workpiece into the V-opening of the die insert mounted on the lower block, creating plastic deformation along a predetermined bend line. The block's mass and rigidity absorb bending forces while maintaining dimensional stability and alignment throughout the production cycle.
材料
Typically manufactured from high-strength alloy steel (AISI 41404340) or tool steel (D2A2) with hardness ranging from 40-55 HRC. May include surface treatments like nitriding or chrome plating for wear resistance.

常见问题

What is the difference between a lower die block and a die insert?

The lower die block is the main structural component that mounts to the press bed, while the die insert is the removable component that fits into the block and provides the specific V-opening geometry for bending.

How often should lower die blocks be inspected for wear?

Regular visual inspections should occur daily, with detailed dimensional checks every 500 operating hours or as specified by the manufacturer based on material thickness and production volume.
