How to Choose The Best Toolings for A Press Brake

The toolings of the press brake are split in two parts. The punches are situated on the upper end of the ram while the dies are on the bottom. The two pieces are joined on the plate metal to complete the bent.

The process of bending is when the punch of the brake exerts a force onto the die's metal plate. The press brake presses the metal plate through different motors that power the ram. There are three kinds of sources for driving that are mechanical, hydraulic, and servomotors.

Standards of Press Brake Toolings

There are many types of punches and dies. The precision and effectiveness of bending is improved only by selecting the correct matching punches and dies to bend. Standard size tools are easy to replace. Because the design of tooling parts with standard dimensions is consistent.

In this way there is no need to make any adjustments while replacing the dies and punches. They die punches are maintained in the same place to replace them conveniently. The upper parts of the ram of the press brake require a clamping device for fixing the punches. The clamping device is able to hold the punches in place. The punches bend the metal plate by moving the ram.

Die segmentation can facilitate the bending process for various-sized workpieces. A high level of precision is essential for press brake toolings. Particularly the accuracy of punch tip or die shoulders. These parts can come in direct contact with sheet metal during bent. Die or punches that are high-precision will also make adjustments easier in the process of installation.

Types of Punches and Dies

There are three types of press brake dies: V-die (the most commonly used) Z-die, U, and U-die. The minimum flange length shall be at least 4 times the thickness of the material.

The exact angle of bending cannot be established if this is not the situation. The different opening widths of V-die sets match the punches. This way the press brake can bend at various angles and also with different materials.

The three primary types of press brake punches can be classified into three types three types: straight punch, gooseneck punt, and acute punch.

Tools Selection: Considerations to Make

Bending Material

It is essential to decide the type of metal that you would like to bend. The thickness of the metal determines the opening of the die as well as the bending radius and bending angle. Some steels are stronger and more resistant to corrosion than others.

This resistance is referred to as the tensile strength (UTS) of the material. The tensile force of different metals differs, and requires molds with different strengths. In addition, it needs to be considered that the length of the plate determines how many toolings are needed.

The V Opening of Material and the Radius

If the thickness and type of sheet metal are the same, then there is more than one V-die opening size.

The sheet will not become damaged by bending. The plate will stretch if the inner radius is less than that of its sheet of metal. This will cause the workpiece to deform. The deformation won't occur when the radius is larger than the thickness. We must select an area that is smaller than the thickness of the sheet when selecting the V-die opening.
