Press Brake Toolings Design depends on customer workpiece ,It can divided as Punch Selection and Die Set Selection. The rules are as below :
Punching Selection :
- When the small up-leg is longer than the bottom leg, you need a gooseneck punch.
- When the small up-leg is shorter than the bottom leg, any punch shape will work.
- When the small up-leg is equal to the bottom leg, you need an offset acute punch.
Die Selection:
Customer can use the normal rule 8×2 to save the burget.
- First, determine the sheet metal range of metal thicknesses you want to bend. For example, you might need to bend material 2mm through V=16mm Die
- Second, assess the smallest die Set needed by multiplying the thinnest metal by 8. In this case, 3mm material would need the smallest die, hence: 3 × 8 = 24mm, which The Die Set V size round up to 24mm.
- Third, assess the largest Die Set V size needed by multiplying the thickest metal by 8. In this case, the thickest material of 6mm would need the largest die: 6× 8 = 48mm.
You’ve now determined the smallest and largest die you need—2mm and 6mm. To fill in what you need in between, you start with the smallest V size and double its size. In this case, that gives you a 16mm die (2 × 8 = 4). 32mm , 48mm Multi-V Mould .
If Your part doesn’t need a short flange, a narrow offset, or a tight radius, why complicate matters? Follow these three simple rules and you’ll improve angular performance, shorten setup time, and reduce tool operating costs.
Also Durmapress Engineer can design the special Toolings according to customer product request , so you just contact us and send your products drawings is ok .
