The invention provides a lifting hook for replacing a rolling mold of a wheel. The lifting hook is used for lifting the rolling mold to a machine table main shaft, and a machine table main shaft main body extends outwards to form a step section with the diameter smaller than that of the machine table main shaft main body; the lifting hook comprises a lifting appliance main shaft, the lifting appliance main shaft comprises a lap joint part and a lifting appliance main shaft part, the lifting appliance main shaft extends into the rolling mold, and the lifting appliance main shaft part supports the rolling mold; and the lap joint part is in lap joint with the step section, so that the top surface of the lifting appliance main shaft is horizontally aligned with the top surface of the machine table main shaft main body, and the rolling mold is horizontally moved to the machine table main shaft from the lifting appliance main shaft. According to the lifting hook, the inconvenience caused by a mold replacing coaxial sleeving mode is solved, and the rolling mold on the lifting appliance main shaft is smoothly pushed to the machine table main shaft in a lap joint mode.

    本发明提供一种车轮滚型模具换模用的吊钩,用于将滚型模具吊装至机台主轴上,机台主轴主体向外延伸有直径小于机台主轴主体的直径的台阶段;吊钩包括吊具主轴,吊具主轴包括搭接部和吊具主轴部,吊具主轴伸入到滚型模具中,吊具主轴部支撑滚型模具;搭接部搭接到台阶段上,使吊具主轴的顶面与机台主轴主体的顶面水平对齐,用以滚型模具从吊具主轴水平移动到机台主轴上。本发明解决了换模同轴套接方式带来的不便,使用搭接方式,完成吊具主轴上的滚型模具平滑推到机台主轴上。
