Component Specifications

Definition
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.
Working Principle
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.
Materials
Typically manufactured from high-strength alloy steel (AISI 4140, 4340) or tool steel (D2, A2) 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.
Technical Parameters
  • 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
Standards
ISO 9181, DIN 9830

Frequently Asked Questions

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
