Product Description

Tungsten Carbide Reverse Riveting Stop Block
The Tungsten Carbide Reverse Riveting Stop Block is a high-precision positioning component manufactured from ultra-hard tungsten carbide material. Designed for demanding riveting, stamping, assembly, and positioning processes, it features a unique reverse riveting structural design that provides exceptional wear resistance, compressive strength, and corrosion resistance for high-frequency, high-load automated production lines.
Product Features
Extreme Wear Resistance, Exceptional Longevity
  • Material Advantage: High-grade tungsten carbide (WC-Co) with hardness of HRA 90-92, offering 50-100 times the wear resistance of tool steel
  • Longevity Performance: Service life increased by over 10 times compared to traditional alloy stop blocks under continuous impact conditions
Ultra-High Strength, Stable and Reliable
  • Compressive Strength: ≥4000 MPa, capable of withstanding extremely high impact loads without plastic deformation
  • Structural Stability: Special heat treatment and precision machining ensure dimensional stability with no micro-deformation during long-term use
Unique Reverse Riveting Design, Precise Positioning
  • Self-Locking Structure: Angled reverse riveting design creates a self-tightening effect upon impact, preventing loosening
  • Zero Rebound: Effectively absorbs impact energy, ensuring positioning repeatability within ±0.005mm
Broad Environmental Adaptability
  • Corrosion Resistance: Resistant to most oils, coolants, and mild chemical media
  • Temperature Resistance: Operating temperature range from -50°C to 800°C (short-term peak)

Selection Guide
Standard Selection Process
  1. Condition Analysis: Confirm impact frequency, load magnitude, and environmental media
  2. Size Determination: Select based on installation space and required stroke
  3. Accuracy Selection: Choose accuracy grade according to process requirements
  4. Mounting Method: Select press-fit or bolt fixation based on equipment structure
  5. Special Requirements: Such as anti-magnetic, ultra-high temperature resistance, etc.
Customization Services
  • Non-standard sizes and shapes
  • Special cobalt content adjustments
  • Surface coating treatments (e.g., TiN, DLC coatings)
  • Combined stop system design
Installation and Maintenance
Installation Notes
  1. Clean mounting holes to ensure they are free of oil, grease, and debris
  2. Use specialized installation tools and apply pressure evenly
  3. Check flatness and perpendicularity after installation
  4. Initial low-speed break-in operation is recommended
Maintenance Recommendations
  • Regularly clean the working surface to prevent accumulation of hard particles
  • Check fixation status to ensure no loosening
  • Record usage hours to establish a preventive replacement schedule
  • Minor wear can be restored by professional regrinding (up to 2-3 times)
