Front cylinder casting process

Abstract

The invention relates to a front cylinder casting process which comprises the following steps: raw material inspection: inspecting the chemical components and pinhole degree of the raw material; smelting: smelting the raw material into molten aluminium, and inspecting the chemical components and mechanical performance of alloy liquid; pressure casting: performing pressure casting on molten aluminium to form a front cylinder blank body, and inspecting the surface quality and internal quality of a product; trimming: removing flashes and burrs of the front cylinder blank body; thermal treatment: loading the product into a thermal treatment furnace for thermal treatment, inspecting whether parameters on recording paper meet process requirements, inspecting the hardness of the product, and transferring qualified products to the next station; shot blasting: hanging the product on a hanging bracket for shot blasting to product a finished product, and inspecting whether the chromatic aberration of the product is consistent; and finished production inspection: inspecting whether a finished product meets all indexes. The front cylinder casting process can overcome the problems of many procedures and heavy workload of processing technology of the prior art, and can improve the production efficiency; the raw material utilization rate is high, and the production cost is lowered; the cast finished product front cylinder casting is environmentally friendly and practical, and the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a casting process of a front cylinder body. Background technique [0002] The casting level of the front cylinder block of the engine is one of the important symbols to measure the level of a country's manufacturing industry. The current casting process of the front cylinder block of the fuel engine has the disadvantages of high labor intensity and large consumption of raw materials. Not only are there more casting processes, which affects production capacity, but also the weight of castings is heavy and the scrap rate is high. Contents of the invention [0003] In order to overcome the above-mentioned technical problems existing in the prior art, the object of the present invention is to provide a casting process for an engine front cylinder block, which has a simple manufacturing process. [0004] The engine front cylinder block casting process provided by the pr...
