Abstract
The invention provides a casting processing method of a bearing cap. The method comprises the following steps: making a bearing cap die; making a making tool; arranging a pouring gate, a shrinkage head and a gas outlet on the die; putting resin sand in the die, and molding the resin sand; slicking the molded resin sand die, and brushing the surface of the molded resin with a coating; carrying out allotyping and mold assembling on the resin sand die; hanging the resin sand die; arranging a pouring gate cup on the pouring gate of the die, and arranging a shrinkage head cup on the shrinkage head; and preparing an enamel furnace charge. The casting processing method of the bearing cap has the advantages of convenient control of the melting process, high qualified rate of products, and high quality of molten iron; and the bearing cap generated in the invention has the advantages of good structure and performance, reduced fluctuation range of the quality, and high qualified rate.
Description
Technical field
The present invention relates to a kind of casting processing method of step cover, belong to machinery manufacturing technology field.
Background technology
At present, when manufacturing bearing support, need repeatedly to adjust on high-precision lathe by experienced technician just can process qualified parts, efficiency is low, and human factor is large, and cost is high.The melting of bearing support is all adopt water-cooled copper pincers crucible vacuum arc melting button stove to carry out melting, this stove fusion process is complicated, need repeatedly to vacuumize, repeatedly overturn melting, the volatilization of alloying element scaling loss is serious, chemical composition change large and be difficult to control, smelting time is long, simultaneously, also there is the pollution of tungsten alloy electrode alloy, alloying constituent and homogeneity of structure lower, can only the little metal of melting volume, use range is little.
Summary of the invention
The invention provides a kind of casting processing method of step cover, technique is simple, and the quality of bearing support is fine and close, and quality is good, and efficiency is high.
For solving above technical problem, the invention provides following technical scheme: a kind of casting processing method of step cover, comprises the following steps: the mould first making step cover; Prepare fabricating tools; Mould arranges cast gate, rising head, venting port; Resin sand is put into mould, carries out phenolic sand molding; Type is repaiied to the resin sand mould after moulding, and at its surface brush coating; Mould, mould assembling are joined to resin sand mould; Box is carried out to resin sand mould; Sprue cup put by the cast gate of mould, rising head is put and emits cup; Secondly, preparation pool furnace charge, pool furnace charge comprises the water of the refractory mortar of 12-21%, the quartz sand of 36-42% and 41-54%; Pool furnace charge is filled in cupola furnace, makes pool stove, and the eye that blows on the stove of the pool; Temperature in cupola furnace is transferred to 500-700 DEG C, pool bake oven is done; Light a fire in cupola furnace, temperature is elevated to 880 DEG C; Feed in the stove of the pool, the material of dress comprises: the old iron of the coke of 5-6%, the new iron of 36-42%, 16-22%, the steel scrap of 36-42%, the silicon of 0.62-0.7%, the manganese of 0.62-0.7%, the iron of 0.62-0.7%; Temperature in cupola furnace is elevated to 920-1100 DEG C, and the material in Cupola carries out melting; Open cupola furnace, release molten iron, and in molten iron, add copper, the chromium of 0.55%-0.6%, the molybdenum of 0.4%-0.48% of 0.65%-0.75%, temperature when releasing molten iron is 1410-1450 DEG C; With bull ladle molten iron poured in die cavity and cast; Again, take apart and hang tight filament outside casing; The molten iron block splashed when picking tank surface cast; Open casing; Molding sand soil inside and outside cleaning casing medium casting; Foundry goods is put into shotblasting machine and carries out shot peening; After ball blast terminates, shot blast room door is opened automatically, is taken out by foundry goods; Casting grinding is cleared up; Machining is carried out to step cover, according to the position designed, size and number processing threaded hole; After processing threaded hole, varnish is sprayed to cast(ing) surface, carrying out shot peening.The cast(ing) surface having brushed varnish can prevent to get rusty, then after carrying out shot peening, the fine and close light of cast(ing) surface.
The casting processing method of this step cover that the present invention relates to, cupola furnace is adopted to carry out melting, it is convenient that fusion process controls, and conforming product rate is high, change the iron time and melting cycle short, productivity is high, produce chain space compact in design, craft flexibility is good, and running cost is low, pollutant emission is few, improves Working environment and ecotope.This manufacture craft can ensure the high-quality iron liquid of stable acquisition, and cast structure, the performance of generation are good, quality fluctuation scope reduces, qualification rate is high.
