Abstract
The present invention provides a kind of casting method of driving axle of forklift axle housing, the described method comprises the following steps：(1) two casees sub-module designs are used, (2) make sand mold using described resin sand, and above-mentioned raw materials are heated to smelting temperature, form potting syrup by the making of (3) potting syrup, (4) in electric furnace；(5) to described potting syrup is poured into a mould in described resin bonded sand mould, casting is formed after solidification.The casting method of the invention not only overcomes the generation that axle housing easily produces the defects such as lockhole, crackle in casting process well, while also improving molten steel Utilization rate；Axle housing casting can be directly cast out, casting finished products high precision, processing technology thereof is simple.
Description
Technical field
The present invention relates to fork truck part manufacturing technology field, and in particular to a kind of casting method of driving axle of forklift axle housing.
Background technology
Because rear axle housing structure complex wall thickness is uneven, there are many deficiencies in known casting method, such as：Because the knot of casting
Structure manufacturability is bad, causes to be very easy to crack, and is difficult to solve the problems, such as surface folding and feeding, the finished product cast being made
Not enough, not only casting process is more for hardness, influences production capacity, while the precision of casting cannot be effectively ensured, percent defective is higher.
The content of the invention
In view of the shortcomings of the prior art, the present invention provides a kind of casting method of driving axle of forklift axle housing, the casting method is not
The generation that axle housing easily produces the defects such as lockhole, crackle in casting process is only overcome well, while also improving molten steel
Utilization rate；Axle housing casting can be directly cast out, casting finished products high precision, processing technology thereof is simple.
To realize object above, technical scheme is achieved by the following technical programs：
A kind of casting method of driving axle of forklift axle housing, the described method comprises the following steps：
(1) two casees sub-module designs are used, die joint is selected at the earhole horizontal center line of rear axle housing two, according to diverse location
Thermal center size, corresponding rising head is respectively provided with, to meet feeding requirement；
(2) make sand mold using described resin sand, with forming resin bonded sand mould after mould mould assembling, the axial line of resin bonded sand mould with
Horizontal plane is perpendicular, touches for two and down gate is respectively equipped with mould assembling, and two down gates are connected by horizontal runway；
(3) making of potting syrup, the degree of its material chemical component is as follows：C：2.4-3.2%；Si：0.5-
1.5%；Mn：0.3-1.2%；P：0.01%；S：0.02%；Mg：0.04-0.05%；RE：0.01-0.015%；Cu：0.2-
0.4% and Cr：0.3-1.5%；Remaining is Fe；
(4) above-mentioned raw materials are heated to smelting temperature in electric furnace, make alloy fully melt to form molten iron, in ladle
Nodulizer, and coverage inoculator are put into the hole built, molten iron is poured into ladle carries out nodularization, inoculation, and formation is poured
Fluid injection；
(5) to described potting syrup is poured into a mould in described resin bonded sand mould, automatic modeling crankshaft casting is formed after solidification, is used on rear axle housing
External chill be retinue external chill, it is then described to being poured into a mould in described resin bonded sand mould to strengthen the chilling action of chill
Potting syrup, forms casting after solidification.
The present invention provides a kind of casting method of driving axle of forklift axle housing, and advantage is compared with prior art：
The casting method of the invention not only overcomes axle housing and easily produces lockhole, crackle etc. to lack in casting process well
Sunken generation, while also improving molten steel Utilization rate；Axle housing casting, casting finished products high precision, processing system can directly be cast out
Make process is simple.
