• 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,...

• 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...
