Abstract

The invention discloses a forming method of the compressor shell. The forming method can make the compressor shell disposable stamping forming, welding is not needed, the production efficiency is improved, and the strength of the formed compressor shell is high. The invention further discloses a compressor which is the disposable stamping forming and has relatively good strength. The forming method of the compressor shell comprises the following. Steps A, preparing the inner cavities of the corresponding compressor shell, or a plurality of mold cores of the holes, the mold core is an abrasivemold core; steps B, the abrasive mold core prepared in the step A is arranged in a compressor shell forming mold, injecting wax to prepare a shell wax embryo which is wrapped on the abrasive mould core; steps C, coating abrasive on the outer embryo of the shell wax; steps D, removing the wax embryo to form a sand shell with a cavity; steps E , pouring metal into the cavity of the abrasive shell toform a compressor shell; Steps F, crushing the abrasive mold core in the compressor shell to remove abrasive inside and outside the compressor shell.

Description

technical field [0001] The invention belongs to the field of compressors, and relates to a molding method of a compressor casing and a compressor, in particular to a molding method of an oil-free and water-lubricated single-screw compressor casing and the oil-free and water-lubricated single-screw compressor. Background technique [0002] At present, the research on oil-free water-lubricated single-screw compressors is becoming more and more active. Many countries and enterprises have begun to explore the road of oil-free screw compressors on the basis of the original oil-injected screw compressor models. In fields requiring high gas quality, such as textiles, metallurgy, food, chemical industry, medicine, petroleum and air separation, etc., where pure oil-free compressed air is required, oil-free single-screw compressors can provide high-quality compressed gas to meet Various needs. Among them, the casing is a key part of the worm compressor, and all positioning dimensions...
