• Types of press brake tooling Ⅰ

  Oct 02, 2025

  Now we need to move to the “proper tooling” which means choosing the tool from the catalog which will be good to bend your part or what mainly should be ordered for your production. And to speak about it we need to make a complete brief of tooling types and possibilities. We will try not to base on any tooling system but just the possible geometry of tools and their possibilities for bending.   If you have the beginner level it is reasonable also to make a small introduction to press brake tooling itself and to divide it into the simple following categories:   Bending punch - an upper tool so the tool will be attached directly to the moveable beam of the press brake or upper holder on the beam and will be moved together with the beam. We select punch based on the nece...

• What are the upper and lower tools of the press brake?

  Oct 02, 2025

  What are the upper and lower tools of the press brake ?  Let's see how the tools are classified     1. The press brake tools include L-shaped, R-shaped, U-shaped, and Z-shaped press tools.   2. The upper tool of the press brake has different angles of 90 degrees, 88 degrees, 45 degrees, 30 degrees, 20 degrees, and 15 degrees. The lower tool is generally divided into 400mm, 200mm, 100mm, 50mm, 40mm, 20mm, 15mm, 10mm, totaling 835mm.   3. The lower tool of the press brake has 4~18V double groove and single groove, with different groove widths, as well as R lower tool, sharp angle lower tool, flattening tool, etc.   4. The upper and lower tools are divided into sections and overall: the upper tool is generally divided into 300mm, 200mm, 100mm, 100mm, 50mm, 40mm,...

• What is the relationship between the slot width of the CNC bending machine and the plate thickness

  Oct 02, 2025

  The relationship between the notch width of the lower die of the CNC bending machine mold and the plate thickness is a question that many metal processing manufacturers will ask. Now the recognized calculation formula in the market is: V groove width = plate thickness *8. This is a common calculation formula in the market, but it also hides a disadvantage. For workpieces that require precision, is this formula still applicable? The result is that it does not completely match. Because this formula is only suitable for precision bending, not for suspended bending and close bending. At the same time, the ratio of the width of the lower die groove of the bending machine to the plate thickness required by different materials is not necessarily the same.   According to the data summarized a...

• 4 Flattening Bending Solutions For Press Brake Tooling -Hemming Die

  Oct 02, 2025

  The following 4 flattening bending solutions. 1. The traditional way is to change the press brake hemming dies.         2. The Spring Hemming die is used. There is no need to change the mold during the whole process. The top notch is folded and the sharp corner is bent, and the second side bounces the part to flatten the edge in one go.   3. Pneumatic hemming die, it cancels the second spring design and uses a pneumatic device instead. It can be opened when it needs to be flattened, which is more scientific.   4. The U-shaped lower die cooperates with the integrated upper punch for bending and flattening, adjusting the bending stroke to complete job   Jaminnar Press brake hemming dies with spring for flatten, we can change the v opening according...

• Why does the CNC press brake need to add a compensation system

  Jul 04, 2025

  CNC press brake is an important equipment in sheet metal processing, and its working accuracy directly affects the bending accuracy of the workpiece. Why add a compensation system to the CNC press brake during the workpiece bending process, as the maximum force is exerted on both ends of the slider and the reaction force during sheet bending causes concave deformation on the lower surface of the slider.   Why does the CNC press brake need to add a compensation system   In order to eliminate the adverse effects of slider deformation, it is necessary to compensate for the deflection deformation of the slider. The usual compensation methods include hydraulic compensation and mechanical compensation, both of which generate upward elastic deformation in the middle of the Com...

• Selection of press brake tooling

  Oct 02, 2025

  When selecting a press brake tooling, the following factors need to be considered:   1. Material type: It is very important to determine the type of material you will be bending. Different materials require different types of molds to complete bending operations. Common materials include steel plates, aluminum plates, stainless steel plates, etc. Ensure that the selected mold is suitable for the type of material you want to handle.   2. Bending angle and radius: Determine the bending angle and radius you need to achieve. Different molds have different curve shapes and bending angle limitations. Ensure that the selected mold meets your specific needs.   3. Mold quality: The quality of the mold directly affects the bending results and the service life of the mold. Choosing hig...

• Analysis and Solutions to Common Malfunctions of CNC Bending Machines

  May 25, 2025

    一、Mechanical bending machine   Fault 1: The guiding gap between the slider and the guide rail is too large, causing abnormal noise.   This type of malfunction is due to the prolonged use of the guide rail, which has been worn and caused an increase in clearance. It is necessary to check the degree of wear of the guide rail pressure plate, and determine whether to replace the guide rail pressure plate and readjust it to meet the required clearance based on the degree of wear.   Fault 2: Rear gear material transmission failure. The failure of the rear gear material transmission is due to the detachment of the key strip between the transmission shaft and the synchronous belt pulley or the slippage of the synchronous belt.   This type of malfunction requires reasse...

• Bending processes and methods

  May 25, 2025

  Most bending parts are produced using air bending, bottom bending, or folding and hemming. These methods and processes all work in the same way: a punch presses the workpiece into the lower tool of the die. That is why the bending machines which carry out these methods and processes are called press brakes.     Air bending    With air bending, the punch presses the workpiece into the die without pressing it against the walls. Whilst the punch moves down, the sides of the workpiece bend up, which creates the angle. The deeper the punch presses the workpiece into the die, the more acute the angle. A clearance remains between the punch and the die. Air bending is referred to as a path-dependent method, as each angle requires a defined path. The machine control calculates...
