From simple bends to complex shapes, the versatility and precision offered by press brakes have made them indispensable in industries ranging from automotive to aerospace. As technology advances, the capabilities of sheet metal press brakes continue to evolve, offering increased accuracy, efficiency, and automation. Understanding the intricacies of these machines, from their types and applications to their operational techniques, is crucial for anyone involved in the metal fabrication industry.

Introduction to Sheet Metal Press Brake

A sheet metal press brake is a machine tool used in the metalworking industry for bending sheet and plate material, most commonly sheet metal. This equipment plays a crucial role in shaping metal into predetermined angles and forms, facilitating the creation of a wide variety of parts and components essential in numerous industries.

The importance of the sheet metal press brake in the metalworking industry cannot be overstated. It is indispensable for its ability to provide precision and consistency in bending operations, which are fundamental for manufacturing parts used in automotive, aerospace, construction, and electronics sectors, among others. The precision and versatility of press brakes allow manufacturers to produce complex shapes and designs with high accuracy, ensuring the quality and functionality of the final products.

The basic components of a sheet metal press brake include a ram, die, and punch. The ram is the part of the machine that moves up and down, driven by hydraulic or mechanical power. The die is the stationary bottom part where the metal sheet is placed, and the punch is the top part that presses down on the sheet to form it into the desired shape. Modern press brakes often incorporate computer numerical control (CNC) systems to enhance precision and repeatability, making them even more effective and efficient for industrial use.

Components of Sheet Metal Press Brakes

Bed

It is a fixed, flat surface used for the press brake to lie the workpiece. It supports and ensures the bending process is correct and aligned.

Ram

Ram is on the upper part of the press brake, which can be moved downward to exert bending force on the workpiece. It is connected to the punch and directly touches and helps form the metal.

Die

The die is a tooling and part with a specific shape used in the press brake and designed for shaping and forming the material. It is usually installed on the bottom beam.

Punch

The punch is also the tool and part with specific shapes used in the bending process for making materials to form. It is usually installed on the upper beam.

Back gauge

The back gauge is the mechanism and CNC controller installed on the rear of the press brake bending area. It is composed of the fingers and stops and is designed to position the bending material precisely, which can ensure a consistent and accurate bending operation.

Back gauge origin

The back gauge origin is the reference point measured on the back gauge system. It ensures the starting location of the back gauge during the bending operation.

CNC system

CNC is the abbreviation of the computer numerical control. It refers to a control system utilizing computer programs to control the machine movement automatically, which includes back gauge, ram, and other axes.

Upper beam

The upper beam is a movable beam or punch of the press brake, which can exert pressure on the material to perform bending. It fixes the punch and exerts the pressure via vertical movement.

Lower beam

The lower beam plays a vital role in press brake fixing, which can offer support for die or bottom tools. When the upper beam or punch moves vertically to exert bending operations, it will keep stable.

X-axis

The X-axis refers to a horizontal axis that can control the back gauge moving along the press brake length. The operator controls the back-and-forth movement of the back gauge, thus ensuring the flange length.

Y-axis

The y-axis is a vertical axis that can control the movement of the press brake punch or upper beam. The ram’s vertical movement is called the Y axis. If the press brake is equipped with two independent cylinders, the CNC press brake can directly control each side of the cylinder. The left side of the ram is Y1, and the right side of the ram is Y2.

Z axis

The z-axis refers to the horizontal axis that moves or stops along the left and right locations. The Z-axis is used to measure the location and movement of the back gauge.

R axis

The R axis is used to control the back gauge finger’s vertical movement or stop. It can bend complex shapes or achieve multiple bends. The back gauge vertical movement is the R axis, which can be controlled on some CNC press brakes. R1 and R2 refer to the up and down movement of the left and right back gauges.

Sheet support arms

These sheet support arms are extended parts installed on the front of the machine, which are used to support the workpiece during bending. Sometimes, they can measure the workpiece.

Understanding Basic Terminology of Press Brake Machine

Bend Allowance

Bend allowance refers to the deformation or elongation of material necessary to achieve a specific bending angle. It is calculated based on factors such as material thickness, bend radius, and material properties.

Bend Deduction

Bend deduction is the difference between the total flat layout dimensions and the actual length of the bent part. It represents the amount of material consumed during the bending process.

Bottom Dead Center

The bottom dead center is the lowest position the punch or upper beam reaches during its downward stroke in the bending process.

Braking Capacity

Braking capacity refers to the maximum force or tonnage that a press brake can exert when bending a specific material within its operational limits.

Clutch

A clutch is a mechanical component in a press brake that connects or disconnects the power transmission from the motor to the punch. It controls the movement and stopping of the ram during the bending operation.

Bottom Bending

Bottom bending is a technique where the upper beam applies pressure to form the material into the complete shape of the die. Unlike air bending, bottom bending keeps the punch and die in closer proximity, resulting in more surface contact with the metal. This method requires more tonnage but produces bends that closely match the shape of the punch and die.

Air Bending

Air bending is a technique where the material is bent using only three contact points. Unlike other methods, the material does not touch the bottom of the die, allowing for a more flexible and varied bending angle. The angle is controlled by the depth to which the punch descends into the die, rather than the exact shape of the workpiece.

Coining

Coining is a high-precision bending method that presses the material fully into the die to achieve accurate angles and shapes. Originating from the process used to mint coins, this technique uses extremely high tonnage to ensure that the material conforms exactly to the angle of the die.

Springback

Springback is the tendency of material to return to its original shape after being bent. Once the bending force is removed, the material slightly straightens or deforms, which can affect the final angle of the bend.

Daylight

Daylight is the distance between the upper and lower beams of the press brake when it is fully open, with no material or tools inside. This measurement determines the maximum height of material and tooling that the press brake can accommodate, typically ranging from 12 to 24 inches.

History and Evolution

Origins of Press Brake Machines

The earliest iterations of press brake machines were rudimentary, hammer-like tools employed to manually bend metal into desired shapes. These early methods relied heavily on the weight of the tool and gravity to manipulate the metal, which was held in place during the process. This manual technique, however, was limited in both accuracy and speed and posed significant safety risks due to the manual labor involved.

Hydraulic Press Brakes

The early 1900s saw the development of hydraulic press brakes, which revolutionized the bending process. These machines used open- and closed-loop hydraulic systems to apply pressure, allowing for more precise manipulation of the material. Hydraulic press brakes offered significantly improved accuracy and could perform multiple operations quickly and safely, marking a significant advancement over earlier manual methods.

Computer Numeric Control (CNC)

In the 1970s, the advent of computer numeric control (CNC) technology brought about a new era for press brakes. CNC press brakes employed powerful motors to drive a system of arms and levers, precisely guiding the material into the desired shape. These machines provided unparalleled accuracy and could handle complex shapes, setting a new standard in the industry. CNC technology allowed operators to input designs that the machine could replicate with high precision, significantly enhancing productivity and consistency.

Servo Motors

As technology advanced, servo motor-driven press brakes gained popularity. These machines use powerful servo motors connected to a network of electro-mechanical systems to drive the press brake arms. Unlike traditional CNC machines, which require the user to input a design before each bend, servo-controlled press brakes allow for the programmatic input of desired shapes, resulting in more efficient production runs and greater flexibility in manufacturing processes.

Robotics

The integration of robotics into the manufacturing industry has also influenced press brake technology. Robotic press brakes can automatically move and manipulate the material, leading to faster operations and higher accuracy.

How To Operate A Press Brake

Understanding Press Brake Forming

To operate a press brake efficiently, it’s essential to grasp the principles of press brake forming. This process involves using a punch and die set at a specific angle to bend or cut metal into various shapes and sizes.

At the core of brake forming is force, often measured in tonnage. Tonnage indicates the amount of pressure the punch can exert on the metal during a bend. The rule is simple: the thicker the material, the higher the tonnage required.

In addition to tonnage, bending length is another critical factor. Bending length refers to the longest part of the metal to be bent. For instance, if a machine can handle up to 14 feet of metal bending, any sheet longer than that would be too large for that machine.

Different fabrication jobs require machines with varying tonnages and bending lengths, depending on the size and thickness of the material being worked on. These specifications are crucial because they determine the load limit of the press brake, often given in tons per inch.

Using incorrect tonnage or bending length can lead to tool damage or even tool destruction.
