A press brake is a machine tool for metal forming, which can bend and shape metal sheets.
press brakes are commonly used in sheet metal processing and manufacturing industries, such as construction, automobile, aerospace, and other industries.
Generally speaking, the workpieces manufactured by the press brake have different shapes, which can be simple or complex parts.
The press brake is equipped with different pressure systems, including mechanical, hydraulic, electric, and pneumatic pressure systems.
The power device applies pressure to the ram, drives the upper die to move downward, and presses the metal plate into the lower die.
In this way, a bending is completed. After repeated and accurate bending, the required workpiece is finally finished.
The die of the press brake is divided into the upper die(punch) and the lower die.
The upper die and lower die of different shapes act on the plate together to form workpieces of different shapes.
Overview of Press Brake Tools and Accessories
Different Types of Press Brake Tools and Their Functions
The tools of the press brake include conventional die assembly, upper die (punch), and V-shaped die.
It is necessary to select different press brake dies according to different metal sheets.
For example, for metal plates with high tensile strength, the hardness of the die should also match the plate.
Otherwise, it will cause damage to the die or inaccurate bending of the workpiece.
The conventional tooling group includes an upper die and a lower die, and the two matching dies to bend the metal sheet together.
The punch is generally made of materials with high hardness, which can effectively extrude or cut the plates.
The lower die also needs the same hard material, as the punch will press the plate into the lower die.
The upper die (punch) of the press brake has some special shapes.
These punches with special shapes and angles can process workpieces with specific shapes.
These punches include standard punch, gooseneck punch, sash punch, arrow punch, acute punch,etc.
The materials used for press brake dies are generally hardened steel, such as chromium-molybdenum steel.
The use of materials with higher hardness can prevent punch cracking caused by excessive pressure and plate hardness.
The lower die of the press brake can also be divided into the V-shape die, U-shape die, single die, and double die.
The material of V-shape and U-shape dies is the same as that of the punch, and they are durable materials with high hardness.
The opening size of the V-shape die will affect the selection of the bending radius of the workpiece and the selection of the bending method.
The groove of the lower die is matched with the upper die so that the sheet can be fixed and form the final shape of the workpiece.
These punches and dies are the main tools for the press brake.
The press brake also has some other very important auxiliary tools, including the back gauge, clamping tool, support rack, etc.
The other parts of the press brake are combined to ensure the accuracy of the bending position, angle and speed.
In this way, the accuracy and quality of the workpiece can be improved.
Using High-Quality Press Brakes Tools and Accessories
The importance of using high-quality press brake punches and dies and accessories is self-evident.
Precise press brake dies and other accessories can improve the accuracy of parts.
The material of the punch and die should be hard enough to prevent it from being worn and broken.
High-quality tooling materials can also extend the service life of the tooling and keep the mold from deformation.
Good tooling quality can ensure the quality of the workpiece bending, thereby reducing the error of the parts.
It can improve the production efficiency of the press brake and reduce production costs.
The dies with high matching degrees and quality are very efficient in sheet bending.
Advanced and high-quality accessories can improve the bending speed, accuracy, and final product quality.
For example, the accurate positioning of the backgauge and each axis can improve the accuracy of the flange length and size of the workpiece.
High-quality hydraulic devices can provide stable stroke and avoid bending angles caused by inconsistent speed.
High-quality toolings and accessories can ensure the bending quality of the press brake and prolong the service life of the machine.
Thus, the product quality is guaranteed, the production efficiency is improved, and the production cost is reduced.
Common Press Brake Tools and Accessories
Press Brake Dies and Punches
The die of the press brake is divided into the upper die and lower die, which jointly bend the sheet.
The upper die can be divided into right angle, acute angle, obtuse angle, gooseneck die, standard die, etc.
The lower die includes the V-shaped die, U-shaped die, single groove and double groove die.
The upper die, driven by the ram, presses the metal sheet into the lower die and bends it into a certain shape.
The material of the die is usually steel with high hardness, so as to prevent the die from breaking.
Angle Gauges and Protractors for Measuring Bend Angles
When bending, the tools used to measure the bending angle of the metal plate are called angle gauge and protractor.
Press brake punches and dies bend metal sheets into different shapes and angles.
In order to ensure the accuracy of bending angle, angle gauge and protractor can be used.
Use the angle gauge and protractor to correct the bending angle and ensure that the bending angle and size are correct.
There are many types of angle gauges and protractors, which are generally supported by steel materials.
Press Brake Tools Lubrication
The use of lubricants can prevent wear caused by long-term use of the press brake die and parts.
Lubricants for the press brake include cutting oil, grease and wax.
The use of lubricants can improve the bending efficiency and service life of the press brake.
Safety Protection Dvices
The press brake needs to be equipped with safety and protective devices to protect the operator from injury during bending.
Safety protection devices include protective fences, gloves and other personal protective equipment.
There are also some special protective devices installed on the operating parts of the press brake.
The brake caliper of the press brake will be equipped with a guard plate, which is a thermal braking part, and the operator will be injured if contacted.
This blog introduces the common press brake tools and the importance of using high-quality tools.
Tools of the press brake include press brake punches and dies, backgauge, protractor, hydraulic device, protective device, etc.
High quality press brake tools are the indispensable part of a high quality press brake.
In the long run, the production cost can be effectively reduced by choosing the press brake with high quality and moderate price.

How Do You Set up A Press Brake Tool?
Before installing the press brake toolings, it is necessary to carefully review the drawings.
Understand the characteristics and thickness of bending materials, flange size, tolerance, bending angle, radius and other parameters.
Next, determine the bending method, air bending, bottom bending or coining.
Then calculate the tonnage required for bending. Different bending methods require different bending forces.
Determine the number of punches and dies to be installed, and then install and align the upper and lower dies.
Slide the punch into the fixture and hold it in place.
Then install the bottom die, do not install it too tightly, and keep it loose.
Lower the punch, slide the punch into the bottom die, and ensure that the upper and lower dies are aligned and close.
Finally, tighten the fastening screws and clamps of the upper and lower dies.
