Multi Cylinder Hydraulic Cone Crusher Lower Head Bushing

The copper sleeve at the lower part of the cone of the cone crusher is one of the key components of the cone crusher. **Detailed Introduction**: This copper sleeve is usually located at the lower part of the cone of the cone crusher and plays an important supporting and sliding role. It closely fits with the cone and, during the operation of the crusher, withstands huge pressure and friction. The main characteristics of the copper sleeve include: - Excellent material: Generally made of copper alloy materials with high hardness and high wear resistance, such as tin bronze. This kind of material has good thermal conductivity and self-lubricating properties, which can reduce friction loss and extend service life. - Precision processing: The dimensional accuracy requirements of the copper sleeve are very high to ensure the fitting accuracy with the cone. Its surface is usually finely processed with high smoothness, which can reduce frictional resistance and improve the working efficiency of the crusher. - Reasonable structural design: The structural design of the copper sleeve usually takes into account factors such as heat dissipation, lubrication, and convenient installation. For example, oil grooves or oil holes may be designed to facilitate the circulation of lubricating oil and reduce the operating temperature. **Manufacturing Process**: 1. Material selection: According to the usage requirements and performance characteristics of the copper sleeve, select an appropriate copper alloy material. Common materials include tin bronze, aluminum bronze, etc. 2. Casting or forging blanks: According to the shape and size requirements of the copper sleeve, use casting or forging methods to manufacture blanks. Casting can obtain blanks with complex shapes, but subsequent processing may be required to improve accuracy; forging can make the material more dense and improve strength and wear resistance. 3. Rough machining: Perform preliminary machining on the blank, such as turning and milling, to remove excess material and make it close to the final shape and size. 4. Heat treatment: According to the characteristics and requirements of the material, perform appropriate heat treatment on the copper sleeve, such as annealing and quenching, to improve its hardness, strength and wear resistance. 5. Fine machining: Use high-precision processing equipment, such as CNC lathes and grinding machines, to perform fine machining on the copper sleeve to ensure dimensional accuracy and surface quality. This includes processing parts such as inner holes, outer circles, and end faces, as well as processing structures such as oil grooves and oil holes. 6. Quality inspection: Perform strict quality inspection on the processed copper sleeve, including dimensional accuracy inspection, hardness testing, and surface quality inspection. Ensure that the copper sleeve meets the design requirements and relevant standards. 7. Surface treatment: According to needs, perform surface treatment on the copper sleeve, such as chrome plating and zinc plating, to improve its corrosion resistance and aesthetics. 8. Assembly and debugging: Install the copper sleeve on the cone of the cone crusher and perform debugging to ensure its fitting accuracy and working performance with the cone. During the manufacturing process of the copper sleeve at the lower part of the cone of the cone crusher, the quality of each link needs to be strictly controlled to ensure the performance and reliability of the copper sleeve. At the same time, reasonable design and manufacturing should be carried out according to different crusher models and working requirements to meet the needs of practical applications.
