What are the characteristics of the manufacturing process and materials for coal mining machine picks?
The cutter of a coal mining machine is an important component used as a tool for cutting and crushing coal mine rock layers. The manufacturing process and materials of shearer picks have the following characteristics:
Material characteristics: The cutting teeth of the coal mining machine usually use hard alloy as the blade material. Hard alloys have the characteristics of high hardness, wear resistance, and good impact resistance, and can maintain good cutting performance in harsh working environments. In addition, the machining performance of hard alloys is also good, which can be used for precision tool manufacturing.
Manufacturing process: (1) Raw material selection: Using high-quality and reliable hard alloy materials on the market to ensure the hardness and wear resistance of the blades. (2) Powder metallurgy process: Generally, powder metallurgy process is used to prepare hard alloy blades. This process has the advantages of high efficiency, energy conservation, and low cost. It can produce blades with complex shapes, and has uniform chemical composition and good physical properties. (3) Heat treatment process: In order to improve the hardness and wear resistance of hard alloy blades, heat treatment is required. Usually, vacuum quenching or gas quenching processes are used to achieve high hardness on the surface of the blade and certain toughness inside, thereby improving the service life of the blade. (4) Precision machining technology: In order to ensure the accuracy and surface quality of the blade, precision machining is required. Usually, precision grinding and machining are carried out using equipment such as CNC grinding machines, wire cutting machines, and magnetic grinding machines to meet the design requirements of the blade.
Features: (1) High hardness: The blade of the coal mining machine's cutting teeth needs to have high hardness to ensure good cutting performance when cutting and crushing coal mine rock layers. (2) Good wear resistance: The coal mining machine's cutting teeth need to have good wear resistance to extend the service life of the cutting teeth when working under high loads and harsh working environments for a long time. (3) Good impact performance: The cutting teeth of the coal mining machine need to withstand a large impact force when cutting and crushing coal mine rock layers, so they need to have good impact performance to prevent blade breakage and damage. (4) Good cutting performance: The blade of the coal mining machine's cutting teeth needs to have good cutting performance to improve work efficiency and reduce energy consumption. (5) Low cost: The manufacturing process of coal mining machine cutting teeth needs to have the characteristic of low cost to reduce production costs and ensure the quality and performance of the blades.
In summary, the manufacturing process and material selection of shearer cutters need to be based on the actual working environment and requirements, ensuring that the blades have high hardness, wear resistance, good impact performance and cutting performance, in order to improve the working efficiency and durability of the shearer.
