下模座

The lower die shoe is the foundational base component of a stamping die set that supports and aligns all lower die elements during metal forming 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 shoe is a critical structural component in stamping die assemblies, serving as the mounting platform for the die block, punches, guides, and other lower tooling elements. It provides rigidity, alignment precision, and vibration damping during high-force metal stamping processes. Typically mounted to the press bed, it ensures proper die closure and material flow control.

定义
The lower die shoe is a critical structural component in stamping die assemblies, serving as the mounting platform for the die block, punches, guides, and other lower tooling elements. It provides rigidity, alignment precision, and vibration damping during high-force metal stamping processes. Typically mounted to the press bed, it ensures proper die closure and material flow control.
工作原理
The lower die shoe functions as a stable foundation that absorbs and distributes compressive forces during the stamping cycle. It maintains precise alignment with the upper die shoe through guide pins/bushings, ensuring accurate part formation. Its mass and rigidity minimize deflection under load, while its flat mounting surface provides reference for all lower die components.
材料
Typically manufactured from high-strength alloy steel (AISI 41404340) or tool steel (D2A2) with hardness 28-32 HRC. May include stress-relieved cast iron for large dies. Surface finish: Ground to 0.8-1.6 μm Ra for mounting surfaces.
Parallelism
0.03 mm maximum
Thickness Range
50-300 mm
Weight Capacity
5-50 tons depending on size
Flatness Tolerance
±0.02 mm/m
Mounting Hole Pattern
Standard T-slots or threaded holes
标准
ISO 9181DIN 9830

常见问题

What is the difference between lower die shoe and die plate?

The lower die shoe is the structural base that mounts to the press, while the die plate is the removable component that contains the actual forming cavities and is mounted onto the die shoe.

How often should lower die shoes be inspected for wear?

Lower die shoes should be inspected for flatness, surface damage, and guide bushing wear every 50,000-100,000 cycles or during scheduled die maintenance.
