Product Introduction:
Dumbbell pins for coal mines are widely used in equipment such as coal mine scraper conveyors and transfer machines, serving as important guarantees for the stable operation of these devices and the smooth transportation of materials. During coal mining, scraper conveyors and transfer machines are required to transport coal from the mining face to designated locations. Dumbbell pins connect each trough body to form a continuous and stable conveying channel, ensuring the smooth transportation of coal and other materials.
Product Advantages:
Dumbbell pins in coal mine machinery are key components used to connect the middle trough of the scraper conveyor. Their design and performance are crucial to the stability, reliability and mining efficiency of the equipment. Dumbbell pins feature high strength and wear resistance, high-precision fit and connection reliability, quick disassembly and assembly, strong interchangeability, the ability to adapt to harsh working conditions, as well as corrosion resistance and impact load resistance. Reliable connection can ensure the smooth operation of the scraper chain, improve the continuity and efficiency of coal transportation, and extend the service life of the equipment.
Production Process:
Raw material inspection → Cutting → Forging → Normalizing → Quenched and tempered → Shot peening → Rough turning → Rough milling → MT → CMM/GMM → Cleaning packaging
