Abstract
The invention belongs to the field of manufacturing of single-cylinder diesel engine bodies, and particularly relates to a manufacturing technique of a high-strength single-cylinder diesel engine body. The manufacturing technique comprises the following steps: (1) obtaining a mould core by a cold core box core manufacturing method; (2) coating the mould core with refractory coating through flow coating, and assembling the core; (3) smelting iron liquid by using an electric furnace, casting after vermicularizing to obtain a casting blank, performing corrosion-proof spraying after cleaning, and machining and inspecting to obtain a finished high-strength single-cylinder diesel engine body product. The high-strength single-cylinder diesel engine body is high in yield rate and exquisite and attractive in appearance; tensile strength tests show that the tensile strength of the high-strength single-cylinder diesel engine body reaches above 300MPa; the high-strength single-cylinder diesel engine body is stable in size, and has the corrosion-proof capability which is 3 times higher than that of a single-cylinder diesel engine body manufactured by a normal process.
