Press Brake Machine

Main Components:

• Frame – The main body that supports the entire machine.

• Ram – The moving part that drives the punch down.

• Punch – The top tool that presses into the metal.

• Die – The bottom tool that shapes the bend.

• Back Gauge – A mechanical stopper to position the metal accurately.

• Control System – Manual, CNC, or hydraulic control to manage movements and angles.

Types of Press Brake Machines:

1. Mechanical Press Brake
   Uses a flywheel and clutch system – fast but less flexible.

2. Hydraulic Press Brake
   Uses hydraulic cylinders – more precise and powerful; good for thick metal.

3. Servo-Electric Press Brake
   Uses motors instead of hydraulics – clean, energy-efficient, and accurate.

4. Pneumatic Press Brake
   Uses air pressure – suitable for light-duty applications.

Common Bending Techniques:

• Air Bending – The punch doesn't touch the bottom of the die; allows for angle flexibility.

• Bottom Bending – The punch presses metal into the bottom of the die for more accuracy.

• Coining – High pressure flattens the metal into the die; very precise but tool-intensive.

 Advantages of Using a Press Brake:

• High precision in bending

• Suitable for mass production

• Can bend complex shapes

• Programmable (CNC models) for repeatability
