Abstract
The invention discloses a forming process for a battery car steel rim. The forming process is characterized by comprising the following steps that a high-strength aluminum alloy rod is custom-made, the aluminum alloy rod is drawn to form an aluminum alloy profile, straightening treatment is conducted on the aluminum alloy profile, and the section of the aluminum alloy profile is the same as the section of the battery car steel rim in shape; the aluminum alloy profile is cut off according to a fixed length and subjected to aging treatment; spoke mounting holes are punched in the aluminum alloy profile; the aluminum alloy profile is coiled into a ring the same as the battery car steel rim in shape, the diameter of the ring is the same as that of the battery car steel rim, and the two ends of the aluminum alloy profile are polished before coiling; the two ends of the ring-shaped aluminum alloy profile are welded; weld joints are polished; and shaping treatment is conducted on the ring-shaped aluminum alloy profile, and the battery car steel rim is formed. The forming process is simple, and the formed battery car steel rim is high in strength and low in cost.
Description
Technical field
The present invention relates to the manufacture technology field of electromobile steel ring, be specifically related to electromobile steel ring moulding process.
Background technology
In recent years, electromobile is widely used in daily life, brings great convenience to everybody trip.Electricity
Intensity needed for bottle car steel ring is different from automobile, motorcycle, also different from bicycle.At present, automobile, motorcycle steel ring most
By die cast metal technological forming, complex forming technology, cost are high, and the steel ring of bicycle is mostly by Sheet Metal Forming Technology molding,
Although technique is simple, but intensity is the highest.
Summary of the invention
The problem existed in view of currently known technology, the technical problem to be solved in the present invention is to be to provide a kind of technique letter
Single, the electromobile steel ring moulding process that institute's molding electromobile Steel Wheel Intension high cost is low.
The present invention has adopted the following technical scheme that:
Electromobile steel ring moulding process, it is characterised in that comprise the following steps:Customization high-strength aluminum alloy bar；Use aluminum
Alloy bar material draws out aluminium alloy extrusions, and aluminium alloy extrusions stretches process, aluminium alloy extrusions cross section and electromobile steel ring cross section
Shape is identical；Aluminium alloy extrusions customized cut-off Ageing Treatment；Aluminium alloy extrusions upper punch makes spoke installing hole；Aluminum closes
Metal type material rolls into the cast identical with electromobile steel ring shape, and cast diameter is identical with electromobile steel ring diameter, rolls front aluminum
The two ends grinding process of alloy profile；The two ends of cast aluminium alloy extrusions carry out soldering；Weld grinding polishes；Right
Cast aluminium alloy extrusions carries out integer process, and then the molding of electromobile steel ring completes.
Ageing Treatment uses artificial aging method, aging temp 175-185 degree, aging time 6 hours.
Use after technique scheme, electromobile steel ring by the aluminium alloy extrusions stretched through rolling, weld and directly being formed,
Technique is very simple, and production efficiency height, low cost, formed precision are the highest, and the drawing of aluminium alloy extrusions may compare and easily adopts
With high-strength aluminum alloy material, so, the intensity of the electromobile steel ring of institute's molding is the highest.
Detailed description of the invention
The electromobile steel ring moulding process of the present invention, comprises the following steps:Customization high-strength aluminum alloy bar；With aluminum
Alloy bar material is raw material, draws out aluminium alloy extrusions by drawing equipment, and aluminium alloy extrusions stretches process, and the aluminum drawn out closes
Metal type material cross section is identical with electromobile steel ring cross sectional shape；Aluminium alloy extrusions customized cut-off also carries out artificial aging process, time
Effect temperature 175-185 degree, aging time 6 hours；Aluminium alloy extrusions upper punch makes spoke installing hole；Aluminium alloy extrusions is rolled up
Making the cast identical with electromobile steel ring shape, cast diameter is identical with electromobile steel ring diameter, rolls front aluminium alloy extrusions
Two ends grinding process；The two ends of cast aluminium alloy extrusions carry out soldering；Weld grinding polishes；Cast aluminum is closed
Metal type material carries out integer process, and then the molding of electromobile steel ring completes.
