Description
Technical field
The present invention relates to castings production any arts, specifically, being a kind of technique for reducing wheel hub Foundry Production cost.
Background technique
With the development of technology, car widely uses car hub unit.The use scope of hub-bearing unit
Increasingly increase with usage amount, the hub bearing of car goes over most to be to use single-row tapered roller or ball bearing in pairs.Work at present
Skill there are the problem of it is larger for riser, riser neck, product yield is low, and the cleaning of casting difficulty, template utilization rate is low, production efficiency
Low, yield can not meet demand, and production cost is higher, and fuse dosage is big, and existing manual core making does not catch up with production requirement, cause to cast
Defect is cold shut, stomata, and scrap iron is more.
Summary of the invention
In order to solve the above-mentioned technical problem, it the present invention discloses a kind of technique for reducing wheel hub Foundry Production cost, utilizes
This characteristic of the attribute graphitization expansion of spheroidal graphite cast-iron effectively utilizes control pressure riser design scheme, reduces running gate system
Size, while reasonable process layout improves production efficiency and product yield, optimizes to Product Process, carries sand
Tire, saves fuse, and overall plan greatly reduces production cost.
To achieve the goals above, the technical solution that the present invention uses is as follows:
A kind of technique reducing wheel hub Foundry Production cost, including casting ontology are vented riser and satrain relief, air-out needle, son
Core, riser diameter are adjusted to 68mm*80mm, and riser neck size adjusting is 30mm*10mm, by improved plate technique, by template
It is adjusted to three, a type, brings out the inner cavity of wheel hub certainly as cavity plate on upper model in wheel hub Foundry Production.
The present invention is further improved, and adds air-out needle in sub- core.Because gas is not easy to exclude in type chamber and fuse, lead to casting
It is suitable for reading usually because gas hole defect cause give up it is more, among sub- core increase air-out needle can reduce this problem.
The present invention is further improved, and the quantity of air-out needle is one piece, diameter 14mm.
The present invention is further improved, and casting topmost opens up exhaust passage at three.Overflow benefit is played in opening up for exhaust passage
It indents the effect of gas, fine using rear effect, waste product significantly reduces, and comprehensive rejection rate is reduced to 3%.
Beneficial effects of the present invention: the present invention uses improved casting technique, and rejection rate reduces 5 percent, can save
Save great amount of cost, change production method and process program, improve the production efficiency of one third, ensure that manufacturing schedule and
It supplies on schedule, improves product yield 10, reduce iron liquid consumption, 40,000 can reduce the cost of raw material 56.7 ten thousand
Member.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be described in further detail, the reality
It applies example for explaining only the invention, protection scope of the present invention is not constituted and limited.
Embodiment: a kind of technique reducing wheel hub Foundry Production cost, including casting ontology, exhaust riser are emitted with overflow
Mouth, air-out needle, sub- core, riser diameter are adjusted to 68mm*80mm, and riser neck size adjusting is 30mm*10mm, pass through improved plate
Template is adjusted to three, a type, takes the inner cavity of wheel hub certainly as cavity plate on upper model out of in wheel hub Foundry Production by technique
Come.
In the present embodiment, for G. Iron Castings, riser, riser neck are big, iron ball can be made once to shrink in process of setting
The iron liquid overflowed during graphite expansion afterwards can not discharge, and sand mold will necessarily be made to expand in this way, cause casting loose, hold
Easily there is casting flaw, by the improvement to riser and riser neck, improve product yield, solves asking for casting cleaning hardly possible
Topic.
In the present embodiment, template technology arrangement is made an adjustment, three, a type is adjusted to by a type two pieces, improves three points
One of production efficiency, mitigated production and supply relationship, while decreasing cold shut defect.By the inner cavity of wheel hub on upper model
As cavity plate from bringing out, remove electric original big cover core, so that depanning is smooth, easy to operate, save production cost and
Labour improves production efficiency.
In the present embodiment, because gas is not easy to exclude in type chamber and fuse, cause casting suitable for reading usually because gas hole defect causes to give up
It is more, increase the air-out needle of diameter 14mm among sub- core, casting topmost opens up exhaust passage at three, plays overflow feeding row
Gas effect, effect is fine after implementation, and waste product significantly reduces, and total lattice rejection rate is reduced to 3 percent.
Basic principles and main features and advantage of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
