• 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 die 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 to...

• 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

  Analysis and Solutions to Common Malfunctions of CNC Bending Machines       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 t...

• Bending processes and methods

  May 25, 2025

  Bending processes and methods   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...
