Description
Technical field
The invention belongs to wheel hub manufacturing technology field, in particular to a kind of hub manufacturing technology.
Background technique
Traditional wheel rim manufacture craft generally includes following steps: blanking → typewriting → edge rolling → pressing → butt welding → plane slag
→ rolling → end is cut → polish → be flared → mono- rolling → bis- rolling → tri- rollings → expansion → air-leakage test → valve holes.Above-mentioned work
In skill, the expansion of wheel rim is only carried out once, since expansion mold section is when expanding outwardly, is had between two mold sections of arbitrary neighborhood
It has the gap, causes wheel rim to fail expansion at gap completely, and then generate deviation from circular from, so that being easy when the subsequent cooperation with spoke
There is deviation.Meanwhile in order to improve the intensity of wheel hub and integral load ability, existing wheel rim generally can be in two side flange of wheel rim
Groove in welded reinforcement ring, but since the material cost, processing cost, welding cost of reinforced steel bar ring are higher, and manufacture this
The unmature special equipment of the product of structure, production efficiency is lower, so gradually being replaced by wheel rim folded edges.
Traditional spoke manufacture craft generally includes following steps: compound die blanking band mesoporous and screw hole → spinning → rushes wind
Hole → air holes chamfering → expansion screw hole → screw hole chamfering → turning, rushes spinning after mesoporous and screw hole, when spinning feeding, workpiece and positioning
Being inevitably present certain bias causes spinning the bias of shape and mesoporous and screw hole distribution circle occur, and rear road turning is with spiral shell
It is positioned on the basis of hole, when spinning bias is bigger, as soon as the thickness difference in turning week is bigger, and it is more unfavorable to dynamic balancing.First in punching
There is also as following drawbacks for the technique of hole spinning again: (1), spinning tail top holding area is small causes flatness after spinning poor；(2), by
Have an impact in spinning process to screw hole position tolerance, when screw hole position tolerance is overproof to lead to subsequent turning spoke, turning outer diameter position goes out
