What Is a Press Brake and How Does It Work?
A press brake is a metal bending machine that shapes sheet metal by applying force through a punch and die system.
Core Components and Their Functions:
- Ram: The moving part applying force to the punch.
- Bed: The stationary base holding the die.
- Back Gauge: Guides the material for precise positioning.
- Punch and Die: The tools used for bending the sheet metal.
- Control Unit: Manages machine settings and automation.
The press brake works by lowering the ram with the punch onto the sheet metal placed on the die, bending the material to a desired angle.
What Are the Different Types of Press Brakes?
Different press brakes operate using varying mechanisms. Each type has unique advantages and drawbacks.
