Component Specifications

Definition
A bending die is a specialized tool component within a bending tool assembly, designed to create precise angular bends in sheet metal or plate materials through controlled deformation. It works in conjunction with a punch to apply force at specific points, forming materials into desired shapes with accurate angles and radii while maintaining material integrity and dimensional consistency.
Working Principle
The bending die operates on the principle of plastic deformation, where a punch applies downward force on the workpiece against the stationary die. The material undergoes controlled bending around the die's radius, with the die's geometry determining the final bend angle, radius, and shape. The process involves precise alignment, force application, and material flow control to achieve consistent results without cracking or springback issues.
Materials
Tool steel (D2, A2, O1), carbide inserts, hardened to 58-62 HRC for wear resistance; sometimes chrome-plated for corrosion protection

Frequently Asked Questions

What is the difference between a bending die and a bending punch?

The bending die is the stationary bottom tool that supports the material, while the punch is the moving upper tool that applies force. Together they create the bending action.

How do I select the correct V-opening size for a bending die?

V-opening is typically 6-12 times the material thickness. Thinner materials require smaller V-openings, while thicker materials need larger openings to prevent cracking.

What maintenance do bending dies require?

Regular cleaning to remove metal particles, inspection for wear or damage, proper storage to prevent corrosion, and occasional re-sharpening of edges.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
