三辊螺旋孔型轧机的设计开发与试验研究

Design and experimental development of three-roll screw groove rolling mill

介绍了新型三辊螺旋孔型轧机的结构,该轧机由轧辊装置、机架、轧辊压下装置、相位角调节机构、轴向调节装置及送进角调节机构等组成。与传统设备相比,三辊螺旋孔型轧机具有单机生产效率高、材料利用率高等优点,特别适合于轴承套圈坯料等环形件的批量生产。

The compositions and the design ideas of a new type three-roll screw rolling mill are described. The mill is composed of roller device, work stand, roller screwdown device, phase-angle adjusting mechanism, axial adjusting mechanism and feed angle adjusting mechanism, etc. The manufacturing and testing process of a prototype are elaborated. Compared with the traditional equipments, it has high production efficiency and material utilization rate. It is suitable for mass production of ring parts like blanks of bearing rings.
