Bague principale supérieure hydraulique de broyeur à cônes de cylindre multi

The copper sleeve at the upper part of the cone of the cone crusher is an important component. It usually has the following characteristics and functions: Characteristics: - Material: Generally made of wear-resistant copper materials such as tin bronze, which has good wear resistance and thermal conductivity. - Structural design: May have structures such as bosses and steel hoops to increase stability and strength; the inner wall may be provided with a straight oil groove to help improve the lubrication effect. Functions: - Reduce the sliding friction force during equipment operation and reduce power loss. - Protect the steel parts in contact with it from wear and prolong the service life of related components. Its manufacturing process may include the following steps: 1. Material preparation: Select an appropriate copper material, such as tin bronze with good wear resistance and mechanical properties. 2. Blank manufacturing: Manufacture the blank of the copper sleeve by methods such as casting or forging. 3. Rough machining: Perform preliminary machining on the blank, such as turning, to make it close to the final shape and size. 4. Inner hole machining: This is one of the key steps. It is necessary to ensure the dimensional accuracy and surface quality of the inner hole. For machining long and large-diameter inner holes, special boring tools may be needed. For example, special tooling is used on a lathe to ensure machining stability and accuracy. When machining the inner conical hole, pay attention to the measurement and control of the taper size. An inside micrometer and an auxiliary measuring ruler can be used for inspection, and the horizontal diameter of the measured position can be converted into a measured value perpendicular to the conical surface by using trigonometric functions. 5. Oil groove machining: According to the design requirements, machine a straight oil groove on the inner wall of the copper sleeve. 6. Heat treatment: Conduct appropriate heat treatment according to the material and performance requirements to improve the hardness, strength and other properties of the copper sleeve. 7. Fine machining: Includes processes such as grinding and honing to further improve the dimensional accuracy and surface finish of the copper sleeve. 8. Quality inspection: Conduct a comprehensive quality inspection on the copper sleeve, such as dimensional accuracy inspection, surface quality inspection, hardness test, etc., to ensure that it meets relevant standards and requirements. 9. Surface treatment: Perform necessary surface treatment such as rust prevention treatment. In the actual manufacturing process, the specific process steps and parameters may vary depending on factors such as the manufacturer, equipment conditions, and product requirements. At the same time, in order to ensure the normal operation of the cone crusher and prolong the service life of the copper sleeve, some precautions also need to be taken during installation and use, such as correct installation, ensuring lubrication, and avoiding overload.
