Description

technical field [0001] The invention relates to a mechanical thermal processing equipment, in particular to a vertical hydraulic riveting machine. Background technique [0002] At present, the riveting of the fan impeller and the shaft disk usually adopts the traditional riveting method, that is, the rivet is first heated and put into the rivet hole, and then the rivet is thickened to the corresponding size by manual lifting of a sledgehammer, and then manually Hammer shaping to complete the corresponding riveting work. [0003] The above-mentioned traditional rivet riveting process takes a long time to prepare, and sometimes requires the cooperation of multiple people to complete the work. In the specific production process, a large amount of labor is required to complete, the labor intensity is high, and the work efficiency is low. This process is completed by different people. It is difficult to guarantee the riveting quality between the ventilation impeller and the sha...
