Embodiment 2

[0053] An eccentric sleeve combination component, leaving a gap of 5 mm between the outer surface of the cast nylon inner sleeve 4 and the inner hole of the cast steel eccentric sleeve 1; leaving a gap of 5 mm between the inner surface of the cast nylon outer sleeve 2 and the outer circle of the cast steel eccentric sleeve 1 gap; the roughness of the bonded surfaces of the cast nylon inner sleeve 4, the cast nylon outer sleeve 2 and the cast steel eccentric sleeve 1 is 25; the manufacturing process of the eccentric sleeve assembly component uses dilute sulfuric acid and dilute hydrochloric acid during surface activation and cleaning treatment. 1. Dilute nitric acid solution or caustic soda solution was heated to 100oC, soaked or boiled cast nylon jacket or cast nylon inner jacket for 10 minutes; other conditions were the same as in Example 1.

Embodiment 3

[0055] An eccentric sleeve assembly, a gap of 1 mm is left between the outer surface of the cast nylon inner sleeve 4 and the inner hole of the cast steel eccentric sleeve 1; a gap of 1 mm is left between the inner surface of the cast nylon outer sleeve 2 and the outer circle of the cast steel eccentric sleeve 1 Clearance; the surface roughness of the bonded surface of cast nylon inner sleeve 4, cast nylon outer sleeve 2 and cast steel eccentric sleeve 1 is 3.2; the manufacturing process of the eccentric sleeve assembly component uses dilute sulfuric acid and dilute hydrochloric acid during surface activation and cleaning treatment. 1. Dilute nitric acid solution or caustic soda solution was heated to 80oC, soaked or boiled cast nylon jacket or cast nylon inner jacket for 90 minutes; other conditions were the same as in Example 1.

Abstract

The invention relates to an eccentric bushing combined component and a manufacturing process thereof. The eccentric bushing combined component is manufactured by bonding and combining a cast steel eccentric bushing, a casting outer cast nylon bushing and a casting inner cast nylon bushing. The eccentric bushing combined component is of a novel structure and the manufacturing process is a novel process method, the conventional product structure and the casting forming process method are thoroughly abandoned, and the whole process of manufacturing the eccentric bushing combined component is accomplished by employing a split combined structure and a method in which the cooling machining is combined with the bonding. By utilizing the manufacturing process, the phenomenon of core-off is thoroughly prevented, the consistence of a product is greatly improved, the service life of the product is prolonged, the production process is free of odor, and the requirements on environment friendliness are met.

Description

technical field [0001] The invention relates to an eccentric sleeve assembly part and its manufacturing process, in particular to an eccentric sleeve assembly part for a crusher and its manufacturing process. Background technique [0002] Mining industries such as coal mines and mines are inseparable from the use of crushers. Due to the impact of objective factors such as harsh working conditions and long service life of the crusher, the eccentric sleeve assembly parts in the crusher need to be replaced frequently, which seriously affects the production efficiency and economic benefits of the mining enterprise. People have tried to replace the Babbitt alloy commonly used in the past by casting method to form cast nylon (MC nylon) inside and outside the cast steel eccentric sleeve, which has brought a revolution to the mining industry. However, due to the characteristics of cast nylon and cast steel materials, the surface bonding force between cast nylon and cast steel mater...
