Sandvik Cone Crusher copper sleeve

**Detailed Introduction and Manufacturing Process of the Copper Sleeve of Cone Crusher** The copper sleeve of the cone crusher is one of the key components in the cone crusher. Detailed Introduction: The copper sleeves of the cone crusher usually include the eccentric shaft sleeve, the transmission shaft sleeve, and the main shaft bushing, etc. These copper sleeves mainly play important roles such as reducing friction, bearing loads, positioning, and guiding. The copper sleeve has good wear resistance, thermal conductivity, and corrosion resistance, and can operate stably for a long time in a harsh working environment. The eccentric shaft sleeve enables the moving cone to generate eccentric swing, thereby achieving the crushing of materials; the transmission shaft sleeve ensures the smooth operation and power transmission of the transmission shaft; the main shaft bushing provides support and guidance for the main shaft of the crusher. Manufacturing Process (The following is the common manufacturing process flow): 1. Material Selection: Generally, high-purity copper alloys, such as tin bronze, are selected to ensure good mechanical properties and wear resistance. 2. Casting: Make the mold according to the design requirements, and pour the copper alloy melt into the mold to cast the blank of the copper sleeve. 3. Stress Relief Annealing: Eliminate the internal stress generated during the casting process and improve the stability of the material. 4. Rough Machining: Remove the excess material on the surface of the blank through processes such as turning and milling, and preliminarily machine the shape and basic dimensions of the copper sleeve. 5. Drilling and Boring: Process the installation holes and mating holes, etc. according to the design requirements. 6. Heat Treatment: Perform heat treatment such as quenching and tempering on the copper sleeve to improve its hardness and strength. 7. Fine Machining: Use processes such as grinding to further improve the dimensional accuracy and surface finish of the copper sleeve to ensure the mating accuracy with related components. 8. Inspection: Inspect the processed copper sleeve in terms of size, shape, hardness, etc. to ensure its quality meets the requirements. 9. Surface Treatment: Perform treatments such as nickel plating and phosphating to enhance its corrosion resistance and wear resistance. During the manufacturing process, strictly controlling the process parameters and quality of each link is the key to ensuring the quality and performance of the copper sleeve of the cone crusher. Different specifications and models of copper sleeves of cone crushers may have differences in the manufacturing process, and the specific process needs to be adjusted and optimized according to the actual needs. For example, for the eccentric shaft sleeve of a certain model of cone crusher, an aging treatment is added after rough machining during its manufacturing process to further eliminate internal stress and improve the accuracy and stability of subsequent processing. In conclusion, the manufacturing process of the copper sleeve of the cone crusher is highly demanding to ensure its reliable operation and long service life in the crusher.
