Utility Model Patent

Issuing authority : CNIPA

Valid period : 2010/1/20 - 2030/3/19

Utility Model Patent – Technical Description

Our organization holds a Chinese Utility Model Patent granted by the China National Intellectual Property Administration (CNIPA) for an innovative design titled:
“Specialized Grinding Wheel for Rail Grinding Vehicles”
This patent protects a technically optimized structure of a resin-bonded abrasive wheel specifically engineered for use on rail grinding trains operating on mainline and heavy-haul railway networks.
The patented design addresses key operational challenges in rail maintenance, including uneven wear, vibration during high-speed grinding, and insufficient material removal efficiency on complex rail profiles (e.g., switch points, transition zones, and corrugated rails). Key technical features protected under this utility model include:
A reinforced core structure with dual-layer glass fiber wrapping to enhance radial strength and prevent catastrophic failure at high rotational speeds (up to 80 m/s);
An optimized abrasive grain distribution that ensures uniform contact pressure across the rail head, reducing thermal damage and micro-cracking;
A customized segment geometry tailored to match the curvature of standard rail profiles (such as UIC60 and CHN60), improving conformity and grinding precision;
Integrated dynamic balancing features that minimize vibration during operation, thereby extending both wheel life and equipment service intervals.
Unlike ordinary abrasive wheels, this specialized design is not merely a consumable but a precision-engineered component developed through extensive field testing and collaboration with rail maintenance operators. It significantly improves grinding efficiency, reduces downtime, and enhances track safety by effectively removing surface defects such as rolling contact fatigue (RCF), shelling, and corrugation.
The utility model patent underscores our commitment to practical innovation in railway infrastructure maintenance. While utility model patents in China focus on novel structural or functional improvements (rather than fundamental inventions), they are rigorously examined for novelty and practical applicability—making this certification a strong indicator of technical differentiation in the market.
For international partners, this intellectual property demonstrates our capability in application-driven R&D and our dedication to solving real-world challenges in rail asset management through engineered solutions.
Utility Model Patent

Issuing authority : CNIPA

Valid period : 2016/11/23 - 2036/11/22

Utility Model Patent – Technical Description

Our organization holds a Chinese Utility Model Patent granted by the China National Intellectual Property Administration (CNIPA) for an innovative manufacturing tool titled:
“Dual-Layer Mold for Resin-Bonded Grinding Wheels”
This patent protects a novel structural design of a press molding die specifically engineered for the hot-pressing production of high-performance resin-bonded abrasive wheels used in railway and industrial applications.
Unlike conventional single-cavity molds, this patented dual-layer mold assembly integrates two functionally coordinated zones within a single tooling system to achieve superior compaction uniformity, density control, and dimensional accuracy during the wheel forming process.
Technical Innovation
The core innovation lies in the mold’s two-tier pressure distribution mechanism:
The outer layer cavity is optimized for shaping the working face of the grinding wheel, ensuring precise profile conformity (e.g., for rail head contouring);
The inner support layer cavity features a reinforced base structure with controlled venting channels that facilitate even resin flow and gas escape during curing.
This dual-layer configuration enables gradient compaction: higher pressure is applied to the abrasive-rich outer zone for maximum cutting efficiency, while the inner core receives balanced pressure to maintain structural integrity—without causing internal stress cracks or delamination.
Additionally, the mold incorporates:
Precision alignment pins and thermal expansion compensation gaps;
Quick-release mechanisms for efficient demolding;
Surface-hardened steel components for extended service life under repeated high-temperature cycles (typically 150–200°C).
