(2) use described in resin sand make sand mold, resin bonded sand mould is formed after joining mould mould assembling, and the axial line of the resin bonded sand mould described in when making and horizontal plane are perpendicular, the axial line of resin bonded sand mould described after completing is mutually parallel with horizontal plane, described resin bonded sand mould forms the sprue of ￠ 80mm, the ingate list root of ￠ 40mm pours into, and described sprue is connected by vertical runway with ingate;
(3) making of potting syrup, the degree of its material chemical component is as follows: C:5.4-5.6%; Si:5.0-5.2%; Mn:1.5-1.6%; P:0.17%; S:0.12%; Mg:0.05-0.1%; Re:0.02-0.025%; Cu:1.4-1.6%, all the other are Fe;
(4) above-mentioned raw materials is heated in electric furnace smelting temperature, make alloy fully melt the molten iron forming half paddle, in the hole built in hot metal ladle, put into nodulizing agent, and coverage inoculator, molten iron is poured into hot metal ladle and carries out ball, inoculation, form potting syrup;
(5) poured into a mould by centrifuging process in described resin bonded sand mould described in potting syrup, form bearing connector foundry goods after solidifying.
(6) by lathe precision work by shaping for the bearing connector Mechanical processing of casting of step (5).
(3) useful effect
The casting technique of a kind of high strength bearing connector of the present invention, its useful effect is, overcome prior art bearing connector operation more, the problem that workload is big, it is to increase production efficiency; Adopting centrifugal angle, avoid the potting syrup defective quality defect caused of processing, utilization rate of raw materials height, reduces production cost; The casting dimension of the finished product cast out is accurate.
