Press Brake Accessories Explained – ADH Machine Tool

I. Introduction

The press brake plays a vital role in metal fabrication.

It is used for bending and shaping metal sheets, widely used in manufacturing automotive parts, electronic equipment casings, or building structural elements.

Its significance also is its excellent accuracy and controllability, which can bend the metal sheet into a highly precise shape, and keep consistency in mass production.

However, a high-quality press brake itself can’t ensure the best production results.

In the metal fabrication industry, each detail is of pivotal importance, which is why press brake accessories should be emphasized.

Press brake accessories are the additional tools to optimize press brake properties, which include but are not limited to blades (used to cut the metal sheet), dies (used to bend the metal sheet), back gauge (used to control the bending angle, and length), clamp (used to fix the metal sheet), support shelves (used to support the metal sheet).

Our passage will discuss the importance of the press brake accessories and their excellent functions in optimizing the properties.

II. Understanding Press Brakes

Basic functions

Position: the press brake positions the sheet via a back gauge to make the bending accuracy.

Bending: the press brake exerts pressure on the metal sheet to achieve bending via the upper die and bottom die.

Control: the modern press brake is usually equipped with a CNC system to achieve accurate control during the bending process.

Types of press brake

Mechanical press brake: this is a traditional type of press brake, powered by an electric motor and flywheel. It achieves sheet bending by mechanical force. Although the mechanical press brake has its advantages in speed and repeatable precision, its safety and energy consumption are generally inferior to modern hydraulic and electric press brakes.

Hydraulic press brake: this hydraulic press brake adopts hydraulic oil as the working medium. It bends the sheet through the pressure generated by the hydraulic cylinder to push the ram (that is top die). Its advantages lie in offering more powerful bending force and better control, especially when dealing with thick sheets.

Electric press brake: the electric press brake utilizes a servo motor to drive the ram movement directly, which can achieve faster speed and higher precision. Electric press brake stands out in energy-saving and environmental aspects, also the cost of maintenance is relatively low.

Role in metal fabrication

The press brake is an important metal sheet production equipment, that can achieve various metal manufacturing via high accuracy bending operation.

It can create complex shapes of components to meet multiple design needs.

It can keep parts accurate and consistent which is important for mass production.

It also can improve working efficiency, and reduce working time and labor cost.
