Product Feature And Application

Tangshan Yuexin Machinery Manufacturing Co., Ltd.'s core components have undergone specialized process optimization, ensuring both quality and performance: the panel is precision-machined using a CNC gantry milling machine and surface nitriding treatment, achieving standard flatness and smoothness, resulting in a flawless appearance for cast tunnel segments; the positioning pin sleeves are made of Cr12MoV wear-resistant steel and vacuum-quenched, ensuring high precision and long wear life, guaranteeing a segment splicing error of ≤0.5mm; the sealing system uses special weather-resistant rubber, suitable for the high-temperature and high-humidity environment of concrete pouring, eliminating grout leakage. It also supports mold upgrades and component replacement, accurately replicating existing mold drawings to fully meet the maintenance and modification needs of different manufacturers' subway tunnel segment molds.

Each component plays a crucial role in tunnel segment production: the panel module directly contacts the concrete, determining the segment forming accuracy and appearance quality; the supporting main ribs and positioning pin sleeves ensure the overall rigidity and repeatability of the mold, guaranteeing consistency in batch production; the sealing strips and opening/closing mechanism adapt to the high-frequency opening and closing of the mold and pouring operations, effectively improving production efficiency. Our products are widely used in underground projects such as subway tunnels and integrated utility tunnels in major cities, serving as core components to ensure the strength, dimensional accuracy, and construction safety of tunnel segments.

Yuexin Machinery's Subway Segment Grinding Tool Accessories strictly adhere to standardized management throughout the entire process: "Drawing Analysis - Raw Material Selection - Precision Machining - Heat Treatment - Comprehensive Testing," ensuring quality control at every stage from source to finished product. In the raw material stage, spectral analysis and ultrasonic testing are performed on the steel to eliminate internal defects and ensure that the material composition and mechanical properties meet standards. In the machining stage, CNC gantry machining centers and grinding machines work together; panel flatness is detected using a laser interferometer, and positioning holes are machined using coordinate boring machines to achieve controllable precision. In the strengthening stage, panel quenching and nitriding treatments improve hardness and wear resistance, while vacuum quenching of the positioning pins ensures stable mechanical properties.

During the assembly and testing phase, core components undergo compatibility testing according to mold assembly standards, and leak simulation tests are conducted on seals to ensure they meet the production conditions of the tunnel segments. In the final inspection phase, a coordinate measuring machine, hardness tester, and flatness tester are used to conduct a full range of inspections, and a detailed inspection report is issued to ensure that each component meets the standards for rail transit equipment.
