Sheet Bending Machine (Press Brake)

Sheet Bending Machine (Press Brake) About

A Sheet Bending Machine, commonly known as a Press Brake, is a machine tool used to bend sheet metal into different shapes and angles by pressing the material between a punch and a die. It is one of the most important machines in sheet metal fabrication industries.

Working Principle

The bending process consists of the following steps:

1. The sheet metal is placed on the lower die.
2. The upper punch moves downward.
3. The sheet is pressed into the die cavity.
4. The desired bend angle is formed.
5. The punch retracts, and the finished component is removed.

The bending angle depends on:

• Punch shape
• Die opening
• Material thickness
• Material type
• Applied force (tonnage)

Main Components

• Machine Frame Heavy welded steel construction for rigidity.
• Hydraulic Cylinders / Servo Drive Provides bending force.
• Ram (Upper Beam) Holds the punch.
• Punch Tool Upper bending tool.
• Die Tool Lower bending tool.
• Back Gauge Positions the sheet accurately.
• CNC Controller Controls bending sequence and dimensions.
• Hydraulic System Generates pressure in hydraulic models.
• Foot Pedal Starts the bending cycle.
• Safety Guards & Light Curtains Protect the operator.
