Press Brake Tooling for Common Straight-Line Bending
Product Introduction
Shengpu Tooling manufactures standard straight punch and double V die sets for common sheet metal bending applications.
A standard straight punch applies bending force vertically along the center line, while a double V die, also called a 2V die, allows operators to switch between two V openings by simply turning the die over. This combination is widely used in sheet metal workshops because it can cover several common material thicknesses with fewer tooling changes.
For small-batch and multi-size production, a standard straight punch with a double V die is a practical press brake tooling solution for reducing setup time, lowering tooling cost, and improving daily bending efficiency.
Core Product Capabilities
- Straight punch rigidity: Center-line load design helps keep vertical bending stable and reduces side loading during normal straight-line bending.
- Double V die efficiency: One lower die includes two V openings, such as V10 + V16, allowing quick switching by flipping the die.
- Matched to common sheet thickness: Suitable for common workshop materials such as 1.0 mm, 1.5 mm, 2.0 mm, and 3.0 mm sheets.
- Tool steel and heat treatment: Available in 42CrMo forged steel, Cr12MoV, and other tool steels, with through hardening around HRC47±2.
- Precision grinding: Precision ground working surfaces help maintain stable bending angles and smooth tooling contact.
- Custom machine fit: Clamping interface, V opening size, tool length, and segmented tooling can be customized according to your press brake model.
Common V Opening Reference
- 1.0 mm sheet: V6–V8, approximate inside radius 1.0–1.3 mm, minimum flange about 5 mm
- 1.5 mm sheet: V10–V12, approximate inside radius 1.7–2.0 mm, minimum flange about 7 mm
- 2.0 mm sheet: V16, approximate inside radius 2.7 mm, minimum flange about 11 mm
- 3.0 mm sheet: V24, approximate inside radius 4.0 mm, minimum flange about 17 mm
Note: The above reference is mainly for low carbon steel air bending. Stainless steel and high-strength steel usually require a wider V opening, while aluminum may use a smaller V opening depending on the material condition and surface requirements.
Selection and Use Tips
- Match the double V die to your main sheet thicknesses. Choose two V openings based on the materials you bend most often.
- Check alignment after flipping the die. Clean chips and dust before use, then check whether the punch tip aligns with the V groove center.
- Start with the 8T rule. For example, a 2 mm sheet can start with a V16 press brake V die, then adjust according to material and bending results.
- Check tonnage and minimum flange length. A smaller V opening is not always better; it may increase tonnage and surface marks.
- Replace or regrind damaged punch tips. A chipped punch edge can directly affect surface quality and bending accuracy.
