Problems solved by technology

[0003] At present, the processing technology of engineering wheels is relatively mature. For example, the patent CN102555667A discloses a manufacturing process of an engineering vehicle integral rim and its rim body, including the rim body. The reel, the pressed material blank, the pressed groove part is made into the groove ring, and the pressed inner rim part is made into the rim body. This kind of rim is easy to process and low in manufacturing cost, but the thickness is uniform, the weight is heavy, and the bearing strength is not high.
Another example is the patent No. "201310229679.7" which discloses a car rim and its spinning process. The external spinning process is used to solve the problems of heavy weight of the existing car rim, high driving resistance and insufficient strength of the car rim, but the use of The structure of the traditional spinning device is complex, and the external spinning process is difficult to control, and the product size accuracy is low. The rim size that meets the requirements must be obtained through post-processing, which increases the processing cost, and the use of materials is not economical enough.
[0004] According to relevant information, although the processing technology of
