Abstract: |
With QJ1546—88 cup head self-sealing rivets in 4mm diameter, an interference-fit riveting experiment was carried out for casting products and parts of three kinds of materials. Products which meet the requirements of airtightness were made by controlling limit deviation of the rivet holes and skewness of axis, adjusting the depth of the dual-angle hole on the sealing surface, and analyzing factors which influence riveting interference quantity. The full-sealed structure can meet the environmental requirement of 0.35MPa inside and outside pressure. |
