Description

Wheel rim and steel rolling for wheel rim Technical Field The utility model relates to a wheel rim and steel rolling materials thereof. Background The tubeless vacuum wheel rim is used as an important bearing component of a modern vehicle, and the structural design and the manufacturing process of the tubeless vacuum wheel rim directly influence the tightness, the light weight level and the use reliability of the wheel. A typical tubeless vacuum wheel rim is comprised of a rim body and a removable rim. The rim body is usually of annular metal structure, one side of which is designed as a fixed rim and is connected with the rim body through an integral molding or welding process to form a stable supporting boundary, and the other side is provided with a mounting groove in which a detachable rim is arranged. Detachable assembly is realized through connecting pieces such as bolts, buckles or locking rings and the like and mounting grooves, and the split type design is convenient for mounting and dismounting of the tire, and simultaneously, convenience of rim maintenance and replacement is improved. The structure can adapt to load requirements under different working conditions while guaranteeing air tightness, and is particularly suitable for the fields of engineering machinery, heavy vehicles and the like. Currently, the mainstream manufacturing process of wheel rims is a roll forming technology of a whole roll of coiled material. The technology is characterized in that a metal coiled material with equal thickness is continuously fed into rolling equipment, and is gradually bent into a required rim section shape through a plurality of rolling procedures. However, the method has the remarkable limitation that the differential design cannot be carried out according to the stress characteristics of different areas of the rim due to uniform thickness of the coiled material, so that the material utilization rate is low and the structural performance is difficult to optimize. Secondly, the constant thickness design may cause local stress concentration, especially in the connection area of the detachable rim and the mounting groove, fatigue crack or deformation is easy to occur after long-term use, and the service life of the rim is influenced. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provide a wheel rim and steel rolling materials thereof. In order to solve the technical problems, the utility model provides a steel strip for a wheel rim, one side of a section of the steel strip comprises a fixed rim, the other side of the section of the steel strip comprises a rim mounting groove, the rim mounting groove is used for detachably clamping a detachable rim, the steel strip further comprises a forming plane used for forming a tire deep disassembly groove by steel rolling, a first bead part is arranged between the forming plane and the fixed rim, a second bead part is arranged between the forming plane and the rim mounting groove, the first bead part is upwards and outwards inclined relative to the forming plane, the second bead part is upwards and outwards inclined relative to the forming plane, the height range of the fixed rim is 12mm to 25mm, an included angle between the first bead part and the forming plane is 10 DEG to 20 DEG, an included angle between the second bead part and the forming plane is 10 DEG to 20 DEG, and the thickness of the steel strip is not equal.
