Cylinder sleeve machining mode

Abstract

The invention discloses a cylinder sleeve machining mode which comprises the steps that casting liquid is injected into a rotary mold, the rotary mold continuously rotates under the condition that molten steel is continuously injected, a variable cavity is formed in the rotary mold, and a cavity of the variable cavity is gradually enlarged in the axial direction of a cylinder sleeve till a complete cylinder sleeve blank is formed; a temporary storage box is arranged on the rotary mold and communicates with the variable cavity, and casting liquid in the temporary storage box is pressed into the variable cavity through a pressure assembly. The technical scheme has the beneficial effects that the centrifugal force generated by rotation of the rotary die can ensure that the manufactured cylinder sleeve blank has no defects and gaps. The variable cavity is used for guaranteeing that the cavity can be continuously filled with casting liquid, it is guaranteed that the cylinder sleeve grows and is formed in the axial direction in the rotary casting process, and the structure of the cylinder sleeve is more stable.

Description

technical field [0001] The invention relates to the technical field of cylinder liner, in particular to a processing method of a cylinder liner. Background technique [0002] The cylinder liner is the abbreviation of the cylinder liner. It is embedded in the cylinder barrel of the cylinder block and forms the combustion chamber together with the piston and the cylinder head. The existing cylinder liner blank processing mostly adopts the method of seamless steel pipe cutting or casting. Since the pipe fittings of the seamless steel pipe are long, deformation is easy to occur during the cutting process, resulting in poor straightness of the cut cylinder liner blank. Subsequent processing brings difficulties. However, the existing casting methods are prone to structural defects. SUMMARY OF THE INVENTION [0003] In view of the defects in the prior art, the present invention provides a cylinder liner processing method, which makes the wall thickness and structure of the proc...
