The present invention relates to a kind of aluminium alloy wheel hub rotary pressing processing techniques, carry out shear spinning molding with casting/forging blank, comprising: spinning mandrel processing, spinning Blank Design and strong rotation processing；The spinning mandrel processing is Ra0.4-Ra0.8um by its type face to type face finish of polishing；The pressure Blank Design draws wheel hub spinning part solid modelling by solid modeling software, and seeks its metal volume, is designed according to constancy of volume shape and calculates forging part spinning blank and cast blank；The strong rotation processing includes: the first passage spinning and the second passage revolves by force molding, and the first passage spinning is precision forging blank, and second passage revolves by force molding and is processed into wheel hub finished product by NC lathing；Present invention process is able to ascend the efficiency and quality of spinning wheel hub, promotes the mechanical performance of tread ring.
Description
Technical field
The present invention relates to technology fields, and in particular to a kind of aluminium alloy wheel hub rotary pressing processing technique.
Background technique
The unsawn timber blank of low pressure casting is directly carried out hot spinning by spinning wheel hub processing technology in the prior art.In
State's patent " a kind of integral aluminum alloy spinning wheel hub and its manufacturing method ", discloses a kind of manufacturing method of spinning wheel hub, just
Machining center hole and outer circumferential edge on beginning blank, are then placed on spinning machine and carry out spinning, and essence is then carried out on numerically-controlled machine tool
Processing.Directly unsawn timber is heated in documents, tread ring unbalance stress in spinning process, mechanical performance is unstable；Automatically
Positioning accuracy is inaccurate, and production process is easily interrupted；It is hung after causing and forms random, unfavorable size adjusting.
Summary of the invention
The present invention provides a kind of aluminium alloy wheel hub rotary pressing processing technique, has the efficiency and product for being able to ascend spinning wheel hub
Matter, the advantages of promoting the mechanical performance of tread ring.
The invention provides the following technical scheme: a kind of aluminium alloy wheel hub rotary pressing processing technique, is carried out by force with casting/forging blank
Power rotary press modelling, comprising: spinning mandrel processing, spinning Blank Design and strong rotation processing；The spinning mandrel processing passes through polishing
Its type face to type face finish is Ra0.4-Ra0.8um；The pressure Blank Design draws wheel hub rotation by solid modeling software
Casting die solid modelling, and its metal volume is sought, it is designed according to constancy of volume shape and calculates forging part spinning blank and cast blank；Institute
Stating strong rotation processing includes: that the first passage spinning and the second passage revolve by force molding, and the first passage spinning is precision forging blank,
Second passage revolves by force molding and is processed into wheel hub finished product by NC lathing.
Further, casting/rough forging material is 6061 aluminium alloys.
Further, 6061 aluminium alloys include: Cu0.15%-0.4%, Mg0.45%-0.9%, Si0.4%- in mass ratio
0.8%, Mn0.15%.
Further, in strong rotation processing: the first passage rotary pressure process parameter is S:50r/min, feed ratio F:20mm/r；The
The strong rotary pressure process parameter of two passages, S:80r/min, feed ratio F:35mm/r.
The beneficial effects of the present invention are: present invention process is able to ascend the efficiency and quality of spinning wheel hub, tread ring is promoted
Mechanical performance.
