The manufacturing method of the copper casting cleaning device.
Casting is a metal formed object obtained by various casting methods, that is, molten liquid metal is injected into a pre-prepared casting mold by casting, injection, suction or other casting method. After subsequent processing such as cooling and grinding, an object having a certain shape, size and performance is obtained. Casting has a long history of application. Ancient people used castings as living utensils. In modern times, castings are mainly used as blanks for mechanical parts. Some precision castings can also be used directly as mechanical parts. Castings account for a large proportion of mechanical products, such as tractors and castings account for 50-70% of the total weight of machinery, agricultural machinery accounts for 40-70%, and machine tools and internal combustion engines account for 70-90%. Among the various types of castings, the largest number of mechanical castings, the most complex shape, the largest number of castings, accounting for about 60% of the total output of castings. Followed by metallurgical ingot molds, engineering pipeline ingot molds and some tools in daily life.
Castings can be classified into steel castings, iron castings, copper castings, aluminum castings, magnesium castings, zinc castings,bronze casting and titanium castings, depending on the metal materials used. Each casting can be further divided into different types depending on its chemical composition or metallographic structure. For example, cast iron can be divided into gray iron castings, ductile iron castings, vermicular iron castings, malleable iron castings, alloy cast iron parts, etc., according to different casting methods, can be divided into ordinary sand castings, metal castings, die castings, centrifugal castings, Continuous casting, investment casting, etc. GS, ceramic castings, electroslag remelting castings, bimetal castings, etc., of which ordinary sand castings are the most widely used, accounting for about 80% of the total casting output. Non-ferrous metal castings such as aluminum, magnesium and zinc are mostly die-casting parts.
If the sand remaining on the surface of the casting is not completely removed, in the process of machining, a large amount of dust will be generated on the one hand, which is harmful to health, and on the other hand, the tool is wasted and the product cost is increased. It is difficult to find a simple and convenient quick cleaning device in the prior art, and the cleaning effect is also extremely unsatisfactory. Therefore, providing cleaning equipment for metal castings has become an urgent issue for those skilled in the art. Poor cleaning quality makes it difficult to effectively remove sand and oil from the surface of the casting.
