Description
Technical field：
The invention belongs to rim for automobile wheel preparing technical fields, and in particular to a kind of widened rim shaped steel of 5.50FL and its system
Make method.
Background technology：
When used a kind of wheel rim on producing existing small sized loader is the widened wheel rims of 5.50F, because can not be straight
The shaped steel of the specification geomery for making steel ring is connect, steel ring manufacturer is all first to cut 5.50F conventional rim steel, so
The steel plate for welding one fixed width therebetween afterwards, the length by extending waist prepares the widened rim shaped steels of 5.50F, to reach
The size requirement of the extension rim used on small sized loader.Fig. 1~2 are respectively the cross-sectional view of common 5.50F rim shaped steels
(it includes the thigh, waist and shank of integral structure, and the front and back both sides connection thigh and shank, thigh length of waist areThigh thickness is 5 ± 0.3mm, and thigh height isShank width is 6.5 ± 0.5mm, and shank is high
Degree isWaist is 136 ± 1.0mm, and waist thickness is), welding prepare 5.50F it is widened
(including thigh, waist and shank, the front and back both sides connection thigh and shank, thigh length of waist are the cross-sectional view of steelThigh thickness is 5 ± 0.3mm, and thigh height isShank width is 6.5 ± 0.5mm, and shank is high
Degree isWaist is 245 ± 1mm, and waist thickness is).The shaped steel life made in this way
The steel ring that output is come will pass through cutting and welding since wheel rim steel used is not global formation, so surface irregularity, holds
The defects of being also easy to produce weld defect, crackle is susceptible to during use or even is broken, serious limit product quality, the harm person
Safety.
