Abstract
The present invention relates to a kind of front-bank rotor housing casting technique, comprise the following steps: the inspection of raw and process materials: check raw material chemical composition and pinhole rate；Melting: raw material is melted into aluminum liquid, and checks chemical composition and the mechanical performance of aluminium alloy；Die casting: aluminum hydraulic pressure is cast front-bank rotor housing idiosome, and checks surface quality and the internal soundness of product；Arrange: remove overlap and the burr of front-bank rotor housing idiosome；Heat treatment: product is put into heat-treatment furnace and carries out heat treatment, whether the parameter on inspection record paper meets technological requirement, and the hardness of inspection product, qualified products move to next station；Ball blast: hung over by product and carry out ball blast on suspension bracket, makes finished product, and checks that finished product aberration is the most consistent；Product inspection: check whether finished product meets indices, overcomes operation in prior art processing technique more, the problem that workload is big, improve production efficiency；Utilization rate of raw materials is high, reduces production cost；The finished product front-bank rotor housing foundry goods environmental protection cast out is practical, reduces labor intensity.
Description
Technical field
The invention belongs to casting technology field, be specifically related to a kind of front-bank rotor housing casting technique.
Background technology
The front-bank rotor housing casting level of electromotor is one of important symbol weighing a national manufacturing industry level height, at present
Fuel engines front-bank rotor housing casting technique to there is labor intensity big, the shortcomings such as raw materials consumption amount is big.Not only casting process is relatively
Many, affect production capacity, casting weight is laid particular stress on simultaneously, and percent defective is higher.
Summary of the invention
For the above-mentioned technical problem overcoming prior art to exist, it is an object of the invention to, it is provided that one is started
Machine front-bank rotor housing casting technique, processing technology thereof is simple.
The electromotor front-bank rotor housing casting technique that the present invention provides, comprises the following steps:
A, the inspection of raw and process materials: check raw material chemical composition and pinhole rate；
B, melting: raw material is melted into aluminum liquid, and checks chemical composition and the mechanical performance of aluminium alloy；
C, die casting: aluminum hydraulic pressure is cast front-bank rotor housing idiosome, and checks surface quality and the internal soundness of product；
D, arrangement: remove overlap and the burr of front-bank rotor housing idiosome；
E, heat treatment: product being put into heat-treatment furnace and carries out heat treatment, whether the parameter on inspection record paper meets technological requirement,
The hardness of inspection product, qualified products move to next station；
F, ball blast: hung over by product and carry out ball blast on suspension bracket, make finished product, and check that finished product aberration is the most consistent；
G, product inspection: check whether finished product meets indices.
Further, in fusion process, raw material is divided into the ratio of virgin material and foundry returns, virgin material and foundry returns to be 6:4.
Further, described smelting temperature is at least 730 °.
The electromotor front-bank rotor housing casting technique that the present invention provides, it has the beneficial effects that, overcomes prior art processing work
In skill, operation is more, the problem that workload is big, improves production efficiency；Utilization rate of raw materials is high, reduces production cost；Casting
The finished product front-bank rotor housing foundry goods environmental protection produced is practical, greatly reduces labor intensity.
Detailed description of the invention
The electromotor front-bank rotor housing casting technique of the present embodiment, comprises the following steps, and 1, raw material incoming inspection: check former
Material chemical composition and pinhole rate, check and qualified move to storehouse, it is ensured that have plastic jacket dust-proof, have approval plate to identify.2, melting: will
Raw material chemical conversion aluminum liquid, virgin material and foundry returns ratio are 6:4, check the chemical composition of aluminium alloy and mechanical performance, 3, die casting: pressure
Casting front-bank rotor housing product, checks surface quality and the internal soundness of product, and qualified products move to next station.4, arrange: remove and produce
The overlap of product, burr etc., check that product levels situation, and qualified products move to next station.5, heat treatment: product is put at heat
Reason stove carries out heat treatment, and whether the parameter on inspection record paper meets technological requirement, and the hardness of inspection product, qualified products move to
Next station；6, ball blast: hung over by product and carry out ball blast by technological requirement on suspension bracket, checks that product surface aberration is the most consistent,
Qualified products move to next station.7, vanning: position and quantity by technological requirement frame up, checks the putting position of product
And quantity is the most correct, qualified products are moved on to storehouse.8, product inspection: check that product inspection report is the most complete, outside product
Seeing whether Meet Customer Requirements, in each Turnover Box, product quantity is the most correct.9, warehouse-in: product is placed on the position specified.
10, warehouse-out inspection: check the outward appearance whether Meet Customer Requirements of product, check that product batches is the most correct, check pull-rod and sample
Whether ingot is ready to, and heat (batch) number is the most correct, checks that outbound quantity is the most correct with quantity of order.
The above, be only presently preferred embodiments of the present invention, and not the technical scope to the present invention makes any limit
System, therefore every any trickle amendment, equivalent variations and modification above example made according to the technical spirit of the present invention, all
Still fall within the range of technical scheme.
