Description

A kind of the maching of Al wheel method
Technical field
The present invention relates to a kind of processing method more particularly to a kind of the maching of Al wheel methods.
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 the maching of Al wheel side is provided Method realizes the automation of wheel hub casting, guarantees that aluminum alloy casting hub is quickly cooled down, prevents what getting rusty from occurring in casting mould to show As.
The technical scheme of the invention to solve the technical problem is: a kind of the maching of Al wheel method, special Sign is, comprising the following steps:
Step S1: lower cylinder movement, control bed die is close to casting hole, two-way cylinder movement, control every group it is positioned opposite Side form synchronization is close to casting hole, and backform is motionless, 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 the underface of bed die, and under the action of two two-way cylinders, every group of side form positioned opposite is opened simultaneously;
Step S4: the piston rod of linear actuator stretches out, and pushes cooling dome to move down, the column barrel of cooling dome covers casting Wheel hub after, meanwhile, driving motor movement, driving motor drives vertical bar rotation, realizes that column barrel is revolved centered on vertical bar Turn, water pump injects cooling water to water receiving pipe fitting, and cooling water is drained in cooling dome by water receiving pipe fitting, and cooling water is from cooling dome Empty cover flows on column barrel, is sprayed cooling water by the spray head on column barrel, is formed on the side wall of wheel hub cold But water mist;
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;
Step S6: the piston rod of linear actuator is fully retracted, and driving motor stalling, side form and bed die reset.
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 bed die from feeding rail from walking to expect that rail enters feeding rail Underface, while under the action of two two-way cylinders, every group of side form positioned opposite opens simultaneously, and cooling water is passed through by water pump In water receiving pipe fitting, cooling water is drained in cooling dome by water receiving pipe fitting, and cooling water flows to column cylinder from the hollow cover of cooling dome On wall, cooling water is sprayed by the spray head on column barrel, meanwhile, under the action of linear actuator, cold water cover is along vertical bar It moves down, forms cooling water mist on the side wall of wheel hub, at the same time, driving motor rotation, driving motor drives vertical bar slow Slow rotation realizes the equably cooling water mist of sprinkling circumferential to wheel hub outer rim, to realize the rapid cooling of wheel hub, pick is abandoned Tradition opens up cooling water channel in mould inside, causes the corrosion to mould inside, and after the completion of cooling, wheel hub is as support hub bar is through upper Material rail is moved to away one end of material rail, sees off from discharging rail by wheel hub, to realize the automation of entire wheel hub manufacture.
