Forged pin rail is one of the key parts in coal mining equipment, especially the travelling track of coal mining machine. The following is a detailed analysis of the forged pin rail:
I. Material and production process
- Material: Forged pin rail is usually made of 42CrMn material. This material has high strength, good wear resistance and anti-fatigue performance, suitable for heavy load and complex working conditions of coal mining equipment.
- Production process: The production process of forged pin rail includes several steps such as die forging, cutting edge, punching and so on. These processes are designed to ensure that the pin rail is dimensionally accurate, has a shape that meets the design requirements, and has excellent mechanical properties and wear resistance. After forging and forming, the upper surface of the travelling post is also quenched to further improve the surface hardness and wear resistance.
Features and Advantages
- High strength: the forged pin rail has high tensile strength and yield strength due to the adoption of high-strength material and forging and forming process, so it is able to withstand the huge load generated by the coal mining machine when walking.
- Abrasion resistance: Through quenching treatment, the surface hardness of the forged pin rail is significantly increased, which enhances its abrasion resistance and prolongs its service life.
- Strong applicability: Forged pin rail is suitable for heavy or large coal mining equipment, which can meet the high requirements of these equipment for travelling rails.
Application scope
Forged pin rails are widely used in coal mining equipment in coal mine production, especially those heavy or large coal mining machines with high requirements for travelling tracks. They are installed in the pin rail seat in the middle slot of scraper conveyor, as the support and guide rail of coal mining machine, and rely on the pin teeth to achieve the traction travelling movement of coal mining machine.
Precautions
- When using the forged pin rail, it is necessary to ensure that it is well coordinated with other parts of the coal mining machine to avoid excessive shock and vibration.
- Regularly check and maintain the forged pin rail, and timely find and deal with potential problems and hidden dangers to ensure its normal operation and prolong its service life.
Summary
As an important part of coal mining equipment, forged pin rail, with its high strength, wear resistance and applicability, plays a key role in the travelling track of coal mining machine. Through strict material selection and production process control, the forged pin rail can meet the high requirements of coal mine production on the performance of the equipment, and provide a strong guarantee for the safe and efficient production of coal mine.
