Press Brake Tooling System
The tooling system of a CNC press brake is essential for shaping and bending sheet metal with precision. It consists of upper and lower tools (punch and die), clamping mechanisms, and alignment systems to ensure accuracy, flexibility, and repeatability in metal forming.
Used to press the material into the die. Different punch shapes allow for various bending profiles.
Straight Punch: Standard for general-purpose bending.
Gooseneck Punch: Allows for return flanges or box bends without collision.
Offset Punch: Used for step bends or offset forms.
Acute Angle Punch: Designed for acute bends (<90°).
Radius Punch: Used to prevent cracking on delicate materials.
Supports the material and defines the bending angle and radius.
V-die: Most common; available in multiple V-openings to suit material thickness.
Radius Die: Used to create rounded bends to avoid cracking.
Acute Die: Forms sharp angles or pre-bending.
Bottoming Die: Used for high-precision bending.
U-die / Hemming Die: For flattening or hemming operations.
Multi-V Die: Features multiple openings for versatility.
Secures the punch and die to the machine. Can be manual or automatic for quick tool changes.
Standard Manual Clamps: Economical, requires manual tightening.
Quick-Release Clamps: Reduces tool change time.
Hydraulic / Pneumatic Clamps: Ideal for CNC automation and high production efficiency.
European vs. American Style: Varies in tool profile and clamping mechanism.
Ensures that tools are perfectly centered and aligned for accurate bending.
Laser Alignment Systems: Projects a beam for fast, visual alignment.
Mechanical Stops / Locators: Precise physical alignment devices.
Tool Seating Detection: Built-in sensors detect correct seating of tools.
WILA or Rolleri Crowning Systems: Compensate for deflection during bending.
