Types of Press Brakes

Mechanical Press Brakes

Mechanical press brakes use a motor to drive a flywheel, providing the force needed for bending. They are known for their straightforward operation and are suitable for a range of applications.

 

Hydraulic Press Brakes

Hydraulic press brakes leverage hydraulic fluid to generate force, offering precision and control in metal bending operations. Their versatility makes them a popular choice in modern fabrication.

 

CNC Press Brakes

Computer Numerical Control (CNC) press brakes take precision to the next level, allowing for automated and programmable bending. This technology enhances efficiency and repeatability in metal forming processes.

 

How Press Brakes Work

Press brakes are essential tools in metal fabrication, used to bend and shape metal sheets into various forms. Understanding how press brakes work involves grasping the basic principles of their operation. Here's a simplified explanation:

 

Frame and Bed

The press brake consists of a sturdy frame and a flatbed where the metal sheet is placed for bending.

 

 

Ram and Die

The key components are the ram (or upper beam) and the die (or lower tool). The metal sheet is positioned between them for the bending process.

 

Hydraulic or Mechanical Power

Press brakes can be powered either hydraulically or mechanically. In hydraulic press brakes, hydraulic fluid generates force to move the ram, while mechanical press brakes use a motor to drive a flywheel, which, in turn, powers the ram.

 

Clamping

The metal sheet is securely clamped between the ram and the die to prevent movement during bending.

 

Bending Process

The bending process begins when the ram descends or moves toward the metal sheet. The force applied by the ram causes the metal to bend to the desired angle.

 

Back Gauge

Some press brakes feature a back gauge, a device that assists in positioning the metal sheet accurately for multiple bends. The back gauge can be manually adjusted or controlled by a computer in CNC press brakes.

 

Die Selection

The die used in the lower tool determines the shape of the bend. Different dies are employed for various bending requirements.

 

 

Control and Precision

In CNC press brakes, the bending process is precisely controlled by a computer. The operator inputs the desired dimensions and angles, and the machine automatically adjusts the ram's position for accurate bending.

 

Release and Unloading

After the bending process is complete, the ram is released, and the metal sheet can be carefully removed from the press brake.

 

Repeatable Process

For mass production or complex projects, the process can be automated and programmed for consistency and repeatability using CNC technology.
