How to Selecting an Appropriate Toolset for your next sheet press brakes?
How to select the right press brake tools for bending has always been an issue. The press brake toolset consists of an upper and lower tooling system. Normally we called press brake top puncher and bottom dies
Choose the correct press brakes punches and dies to account for the material thickness, the bending radius, and the bending way (air bending, bottom bending, or coining). The top punch angles must be equal to or less than the bottom die angle.The tool angle combination should help you compensate for springback, which is the material’s tendency to relax a degree or two when released from the pressure applied to create the bend. The press brake lower die opening must be of a size appropriate for the desired inside sheet bending radius.
How to select a bottom dies? If you select a die opening that is too small, you will damage the part and possibly raise the tonnage to dangerous levels. Select too large of a press brake die opening.
The industry uses various press brake die profiles. The most common is the V die followed by the channel die. There’s a lot to selecting a press brakes die width regardless of the die profile. If the inside bend radius is equal to the material thickness, the rule of thumb is to use a die opening equal to eight times the material thickness. Sometimes, though, the die opening should be 10 to 12 times the material thickness, especially for thicker materials, sometimes for bending Hardox or Weldox high tensile strength metal sheet, die opening should be at least 13-15 times of metal sheet thickness.
How to select the suitable top punches? Except customized tools, press brake punches come in two general styles, the straight top punch and the goose neck top punches for bending deeper C channel or deeper boxes.
