It is rolled onto the size of national regulations and wheel rim is rolled by the peak then inclined-plane of 20 ° ~ 25 ° of inclined downward outward, four rollings
Shape is only responsible for rolling rim part position with five rolling shapes, this two procedures, will not roll other positions again, four times rolling shape leads to wheel rim
Pattern downward vertically will be processed on the outside of wheel rim with stretching by crossing rolling, is ready for five rolling shapes；Five times rolling shape passes through rolling
Inward curl on the outside of the wheel rim of vertical pattern is drawn into when the mode rolled is by four rolling shapes, the exterior portion of entire wheel rim is rolled into
One cricoid structure so as to increase the intensity at position most weak in wheel rim, i.e. wheel rim, effectively improves shock proof ability.
The attainable technique effect of the application：
1st, wheel rim is processed by loop configuration using the process of cold rolling rolling shape, wheel rim forms a torus, at wheel rim not
Can product generated by flange fold, ripple glaze the problems such as, while by repeatedly rolling and flange effectively solves ordinary wheel
Rim overhauling and buildup at the edge of rim in process of production；
2nd, by laboratory test and entrucking road test, single wheel rated load 3750Kg, test load 4875Kg compare ordinary wheel
In the case that rim improves 30%, wheel is continuously driven at 4000Km wheel rimss on inspection without any deformation, product shock resistance
30 ~ 32% are improved than conventional rim.
