The Dual-V Lower Die (also named Double-V Lower Die) is a high-performance press brake tool developed exclusively for precision sheet metal bending. As a core product of Fierte, a professional in sheet metal processing tools, this die is crafted from top-tier steels including 42CrMo4, 42CrMo, and C45, undergoing rigorous hardening and precision grinding to meet the strict demands of industrial bending operations. It integrates advanced structural design and premium materials, becoming an indispensable tool for manufacturers pursuing efficiency and accuracy.
The Dual-V Lower Die features a robust one-piece structure, with the base material selected from high-quality 42CrMo die and C45 bending tool steels. These materials are renowned for their excellent tensile strength, wear resistance, and machinability, laying a solid foundation for the die’s long-term stable operation. The whole-body forging process enhances structural density, effectively preventing deformation under high-pressure bending.
To adapt to different working environments, three professional surface treatment solutions are provided:
Blackened bending die: Forms a dense oxide film on the surface, offering superior corrosion resistance and a sleek black finish, suitable for general industrial environments.
Sandblasted lower die: The surface obtains a uniform matte texture through sandblasting, improving friction performance and preventing workpiece slippage during bending.
Sandblasting + blackening combination: Combines the advantages of both treatments, providing dual protection against wear and rust, ideal for harsh working conditions (e.g., humid or dusty workshops).
The die adopts a compact and optimized structural design, with precise V1/V2 grooves and R1/R2 fillets as key structural features. The groove width and fillet radius are calibrated through strict calculations to match common bending angles (15°-135°). The standardized overall dimensions ensure seamless integration with most press brake models, while the clear marking of structural parameters on the surface facilitates quick identification and replacement.
The innovative Dual-V Lower Die is equipped with two independent V-shaped grooves (V1 and V2) of different sizes, allowing operators to switch between different bending requirements without replacing the die. This design significantly reduces tool changeover time, improving production efficiency by 30% compared to single-V dies. The V-groove surfaces undergo ultra-precision grinding, with a surface roughness of Ra≤0.8μm, ensuring smooth bending and avoiding scratches on the workpiece surface.
The die’s TER structural reinforcement and F1/F2 force-bearing points are scientifically arranged to evenly distribute the pressure from the press brake across the entire die surface. This minimizes stress concentration, preventing local wear and deformation. The bottom of the die is designed with anti-slip grooves, enhancing stability during installation and preventing displacement during high-speed bending operations.
The Dual-V Lower Die complies with international press brake tool standards, compatible with a wide range of models including Amada/Promecam, Trumpf/Wila, Bystronic/Beyeler, LVD type, American standard type, Gasparini type, and Colgar type. It can be directly installed without custom adapters, reducing equipment modification costs.
All components of the die meet ISO 9001 quality management system requirements, with dimensional tolerance controlled within ±0.01mm. The heat-treated lower die undergoes strict hardness testing (HRC48-50) to ensure consistent performance across batches. The standardized design also facilitates interchangeability with other standard press brake tools, improving workshop tool management efficiency.
The adoption of 42CrMo4/42CrMo/C45 high-quality steels and whole-body heat treatment ensures the die’s excellent toughness and wear resistance. It can withstand 100,000+ bending cycles without significant wear, reducing tool replacement frequency.
Precision grinding technology and dual-V groove design enable the die to achieve bending accuracy of ±0.1°, meeting high-precision manufacturing requirements. The quick switching between V-grooves eliminates downtime, significantly improving production efficiency for small-batch and multi-variety production.
Fierte’s in-house R&D team provides custom bending tool solutions, tailoring V-groove size, fillet radius, and overall dimensions according to customer-specific bending projects. Professional technical support ensures the optimal solution for complex bending tasks.
As a cost-effective bending die, it balances high performance and competitive pricing. The durable structure and low maintenance requirements reduce long-term use costs, while the stable performance minimizes product defect rates, bringing significant economic benefits to enterprises.
These steels offer excellent comprehensive mechanical properties, including high tensile strength, wear resistance, and machinability. They respond well to heat treatment, achieving the ideal hardness (HRC48-50) for bending tools, ensuring durability and precision.
