Description
Technical field
The present invention relates to a kind of manufacturing method more particularly to a kind of manufacturing method of wheel hub.
Background technique
During casting aluminium alloy wheel hub, comprising the following steps: needs installation mold on casting machine, mold clamping,
In aluminum water to mold cavity of casting；It needs to cool down wheel hub after the completion of casting；After the completion of cooling, mold is opened, by wheel hub
It takes out.However, the degree of automation is not high in existing wheel hub casting process, degree height is manually participated in.In addition, in aluminum alloy wheel
In the foundry technology process of hub, after the completion of aluminium alloy wheel hub pours, need to cool down aluminium alloy wheel hub.Existing low pressure casting
The mold of forming technique is made, the type of cooling generally has compressed air cooling and cooling by water.For example, Publication No.
The Chinese utility model of CN101530903A discloses " water cooling plant of casting hub mold ", and it is cold that backform is internally provided with backform
But channel, who is flowed in backform cooling duct for cooling, and cooling column is arranged in backform core wheel position, and cooling water is led in cooling duct
Enter, side mode cooling duct is arranged in spoke root, gate cooling structure is arranged at bed die cast gate, it is cooling logical that bed die is also provided with bed die
Road.However, cooling aluminum alloy casting hub mold is carried out using water cooling due to existing, it is cooling logical using being opened up in mould inside
Road injects cooling water in cooling duct, and realization cools down aluminum alloy casting hub, since water there is corrosion to make mold
With after too long, mold is contacted with air, and mold is caused to get rusty.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to the status of the prior art, a kind of manufacturing method of wheel hub is provided, is realized
The phenomenon that automation of wheel hub casting guarantees that aluminum alloy casting hub is quickly cooled down, prevents casting mould from getting rusty.
The technical scheme of the invention to solve the technical problem is: a kind of manufacturing method of wheel hub, which is characterized in that
The following steps are included:
Step S1: lower cylinder, upper cylinder movement control bed die and backform close to casting hole, and two-way cylinder movement, control is often
Group side form synchronization positioned opposite is close to casting hole, and bed die, backform and side form mutually compress to form wheel hub casting mold cavity；
Step S2: casting machine is filled type that the aluminum water of liquid is cast to casting mould is intracavitary；
Step S3: lower cylinder movement, lower bracket drive bed die to withdraw from, and support hub bar is from walking to expect that rail enters feeding rail, from feeding
Rail enters below bed die, and backform moves upwards under the action of upper cylinder, under the action of two two-way cylinders, every group of opposite cloth
The side form set opens simultaneously, and wheel hub drops down on support hub bar；
Step S4: water pump send cooling water to round tube by water pipe, and cooling water is by the spray head on round tube to wheel hub
Lateral border sprinkling, meanwhile, under the action of linear actuator, round tube is moved back and forth up and down along guide post, and spray head is against wheel hub outer rim
It moves up and down, realizes that equably sprinkling water mist circumferential to wheel hub outer rim cools down；
Step S5: after the completion of cooling, wheel hub is moved to through feeding rail one end of discharging rail with support hub bar, will from discharging rail
Wheel hub is seen off.
Preferably, 15 seconds to 30 seconds cooling time of water mist in the step S4.
Further, after lower bracket drives bed die to move downward in the step S3, lower bracket drives bed die rotation, bed die
Casting hole is avoided, to prevent spray head when cooling down to wheel hub, cooling water touches bed die.
Compared with the prior art, the advantages of the present invention are as follows: lower cylinder, upper cylinder movement control bed die and backform are close
Or far from casting hole, two-way cylinder control every group of side form positioned opposite can synchronization action so that side form close up or point
It opens, when casting, bed die, backform and side form mutually compress to form wheel hub casting mold cavity, and casting machine connects to the intracavitary injection aluminum water of type
, lower cylinder movement, lower bracket drives bed die to withdraw from, and support hub bar enters under bed die from walking to expect that rail enters feeding rail from feeding rail
Side, backform move upwards under the action of upper cylinder, while under the action of two two-way cylinders, every group of side form positioned opposite
It opens simultaneously, wheel hub drops down on support hub bar, and water pump send cooling water to round tube by water pipe, and cooling water passes through on round tube
Spray head is sprayed to the lateral border of wheel hub, meanwhile, under the action of linear actuator, round tube is moved back and forth up and down along guide post, spray head
It is moved up and down against wheel hub outer rim, the equably cooling water mist of sprinkling circumferential to wheel hub outer rim is realized, to realize wheel hub
It is quickly cooled down, after the completion of cooling, wheel hub expects one end of rail as support hub bar is moved to through feeding rail, send from discharging rail by wheel hub
It walks, to realize the automation of entire wheel hub manufacture, the present invention moves up and down realization using round tube and cools down to wheel hub, digs
Water channel is begun to cool in casting mould before having abandoned, and wheel hub is cooled down by leading to cooling water realization in cooling water channel,
The front hub caused is cooling, and cooling efficiency is low, and casting mould gets rusty easily, and the present invention is direct with mold due to avoiding cooling water
Contact, it is therefore prevented that mould inside is less prone to the phenomenon that getting rusty after ingress of air, meanwhile, cold mist is directly sprayed
To wheel hub, cooling efficiency is improved.

To cylinder 21 control every group of side form 2 positioned opposite can synchronization action so that side form 2 closes up or separates, when casting, bed die
3, backform 1 and side form 2 mutually compress to form wheel hub casting mold cavity, and casting machine is to the intracavitary injection aluminum water of type, and then, lower cylinder is dynamic
Make, lower bracket 711 drive bed die 3 withdraw from, support hub bar 64 from walk to expect rail 61 enter feeding rail 62, from feeding rail 62 enter bed die 2
Lower section, backform 1 move upwards under the action of upper cylinder, while under the action of two two-way cylinder 21, and every group positioned opposite
Side form 2 open simultaneously, wheel hub 5 drop down onto support hub bar 64 on, water pump send cooling water to round tube 42 by water pipe, cooling water
By the spray head 421 on round tube 42, sprayed to the lateral border of wheel hub 5, meanwhile, under the action of linear actuator, round tube 42 is along leading
It is moved back and forth up and down to column 41, spray head 421 is moved up and down against 5 outer rim of wheel hub, is realized and is circumferentially equably sprayed to 5 outer rim of wheel hub
Mist of sprinkling water is cooling, to realize the rapid cooling of wheel hub 5, after the completion of cooling, wheel hub 5 is as support hub bar 64 is through the shifting of feeding rail 62
It moves to one end of discharging rail 63, is seen off from discharging rail 63 by wheel hub 5, to realize the automation of entire wheel hub manufacture, this hair
It is bright using round tube 42 move up and down realization wheel hub 5 is cooled down, pick abandoned before water channel was begun to cool in casting mould, lead to
It crosses the logical cooling water realization in cooling water channel to cool down wheel hub 5, the front hub 5 caused is cooling, and cooling efficiency is low, casting die
Tool gets rusty easily, and the present invention is directly contacted due to avoiding cooling water with mold, it is therefore prevented that even if mould inside is in ingress of air
It is also less prone to the phenomenon that getting rusty afterwards, meanwhile, cold mist is directly sprayed on wheel hub 5, cooling efficiency is improved.
