Compressor bore casting method

一种压缩机内孔的铸造方法

Abstract

The invention relates to a compressor bore casting method.The compressor bore casting method includes: A, designing a compressor as well as a shape and a structure of a compressor bore, and designing an outer through hole at the corner or turning position of the bore; B, making a die of iron, wherein the die is integrally formed once; C, making a sand core of the bore of chromite sand; D, arranging a rebar in the sand core; E, applying zircon powder coating on the outer portion of the sand core; F, casting in the die and stripping; G, extracting the rebar from a compressor, inspecting whether adhered sand and adhered iron exist or not via the outer through hole, and cleaning.The compressor bore casting method has the advantages that since casting processing substitutes for original solid processing, processing cost is reduced effectively directly, processing time is shortened, production efficiency is improved, and slender bend bores can be designed three-dimensionally optionally according to needs to be beneficial to increase of oil supply or water supply pressure, decrease of compressor design size and improvement on compressor performance.
本发明涉及一种压缩机内孔的铸造方法,该方法包括如下工艺:A、设计好压缩机以及压缩机内孔形状和结构,并在内孔的拐角或转弯处设计有外通孔;B、采用铁制作模具,且模具为一次成型的整体设计;C、内孔的砂芯采用铬铁矿砂材料制作;D、在砂芯内设有钢筋;E、在砂芯外部涂有锆英粉涂料;F、在模具中浇铸成型并脱模;G、从产品中抽出钢筋,通过外通孔检查是否存在黏砂、黏铁并清理干净后即可。采用本发明,不仅改原来的实心加工为铸造加工,直接有效地降低加工成本,减少加工时间,提高生产效率,而且可以根据需要任意进行细小长弯内孔的三维设计,有利于提高内孔的供油或供水压力,减小产品设计体积,促进产品性能提高。
