Roller shutter shaft of fast rolling door and machining method of roller shutter shaft
The invention discloses a roller shutter shaft of a fast rolling door and a machining method thereof.The roller shutter shaft comprises a round pipe, a connecting shaft and a shaft body, the shaft body is of a cylindrical profile structure, a shaft hole is formed in the center of the shaft body, the shaft body is in interference fit with the round pipe, and the shaft body is installed at the two ends of the interior of the round pipe; the outer end faces of the shaft bodies located at the two ends of the circular pipe are flush with the end faces of the corresponding ends of the circular pipe. The connecting shaft is a step shaft, one end of the connecting shaft is in interference fit with the shaft hole and installed in the shaft hole of the shaft body, and the other end of the connecting shaft is located on the outer side of the round pipe. According to the machining method of the roller shutter shaft, the connecting shaft is pressed into the shaft hole of the shaft body firstly through two press-fitting processes, then the shaft body where the connecting shaft is pressed is pressed into the element pipe, and machining of the roller shutter shaft is completed. The shaft body of the roller shutter shaft is in interference fit with the connecting shaft, the shaft body of the roller shutter shaft is in interference fit with the round pipe, the roller shutter shaft is formed through two press-fitting processes in a press-fitting mode, and therefore the whole roller shutter shaft does not need to be welded, machining is convenient, production efficiency is high, and the machined roller shutter shaft is good in stability and long in service life.
本发明公开了一种快卷门卷帘轴及其加工方法，该卷帘轴包括一圆管、连接轴和轴体，所述轴体为圆柱体型材结构，中心设有轴孔，所述轴体与圆管为过盈配合，轴体安装在圆管内部两端，位于圆管两端的轴体的外端面与圆管的对应端端面持平；所述连接轴为台阶轴，其一端与轴孔过盈配合，并安装在轴体的轴孔内，连接轴另一端位于圆管外侧；该卷帘轴的加工方法是通过两道压装工艺，先将连接轴压装在轴体轴孔内，再将压装连接轴的轴体压装到元管内，完成卷帘轴的加工。本发明卷帘轴的轴体与连接轴、轴体与圆管均过盈配合，通过两道压装工艺压装形成，从而使得卷帘轴整体无需焊接，加工方便，生产效率高，且加工后的卷帘轴稳定性好，使用寿命长。
