The Singer-Sided Acute Punch is a specialized press brake punch engineered for precision acute bending in sheet metal processing. Manufactured by Fierte—a trusted leader in bending tools and crowning tables—this acute bending punch is crafted from premium 42CrMo and C45 steels, featuring whole body heat treatment to reach a hardness of HRC48-50. With three versatile design styles and precision machining, it delivers sharp, consistent acute angles, making it an essential tool for industries requiring high-precision sheet metal components.
The Singer-Sided Acute Punch offers three tailored design styles to meet diverse press brake requirements:
Precision Style: Engineered for high-tolerance applications (±0.01mm), ideal for precision components like electronic enclosures.
Tang Style: Features a precision-machined tang for easy installation and alignment, reducing setup time in high-volume production.
European Bevel AFH: Designed for compatibility with European-standard press brakes, ensuring seamless integration with existing equipment.
Each style maintains the punch’s core acute bending capability while adapting to specific operational needs.
Crafted with meticulous attention to detail, the Singer-Sided Acute Punch boasts tight dimensional tolerances. Its working tip is precision-ground to a sharp acute angle, ensuring clean, consistent bends without material damage. The punch’s overall length and shank diameter are optimized for stability during high-pressure bending, with all critical dimensions verified via advanced measurement tools (e.g., coordinate measuring machines) to guarantee compliance with design specifications.
The Singer-Sided Acute Punch features a specialized mechanism that focuses pressure on the bending point, enabling sharp, accurate acute angle formation. The streamlined working surface reduces friction between the punch and sheet metal, minimizing springback—a major challenge in acute bending. The European Bevel AFH design incorporates a beveled edge to further enhance precision, while the Precision Style includes enhanced guiding structures for maximum alignment accuracy. This mechanism ensures that even thin sheet metals (0.3mm) can be bent into acute angles without creasing or deformation.
To withstand the high pressures of acute bending, the Singer-Sided Acute Punch undergoes whole body heat treatment to enhance load-bearing capacity and resistance to fatigue. Its one-piece construction distributes force evenly across the punch’s body, reducing stress on critical components (e.g., working tip, shank). The punch’s shank is reinforced to prevent bending or breakage during operation, ensuring stable performance in continuous production runs.
The Singer-Sided Acute Punch is manufactured from top-grade 42CrMo and C45 steels, selected for their excellent combination of strength, toughness, and wear resistance. These steels undergo strict quality control, including chemical composition analysis and mechanical performance testing, to ensure they meet international standards for precision bending tools.
Key components of the punch are engineered for durability and precision:
Working tip: Precision-ground to a sharp acute angle, with a polished finish to reduce friction and material adhesion.
Shank: Machined to tight tolerances (±0.01mm) for secure attachment to press brakes, with reinforced edges for added strength.
Guiding structures: Integrated into the Precision Style and European Bevel AFH designs, ensuring alignment accuracy and preventing misalignment during bending.
All standard parts are designed for easy maintenance, with replaceable components available to extend the punch’s service life.
The Singer-Sided Acute Punch is specifically optimized for acute angle formation, delivering sharp, consistent bends with tolerances of ±0.01mm. Its specialized mechanism minimizes springback, ensuring that finished components meet exact design requirements without rework. This precision makes it ideal for high-end applications like electronic components and architectural metalwork.
With whole body heat treatment (HRC48-50) and premium 42CrMo/C45 materials, the punch withstands thousands of bending cycles without wear or deformation. Its robust construction resists impact and fatigue, ensuring long service life even in high-volume production environments.
Offering Precision Style, Tang Style, and European Bevel AFH designs, the Singer-Sided Acute Punch adapts to a wide range of press brake models and applications. This versatility eliminates the need for multiple specialized punches, reducing inventory costs and simplifying tool management.
