Experiment method 4.

1 make sure load twists riveting nut whorl core club (see a picture 1) , press a watch the 1 assurance that brings to bear on to set load, maintain 15s, riveting nut should be not taken off buckle or rupture. After purify load, should can use a hand to come back riveting nut, or usable hand comes back after light riveting nut piece. When having a test, the floating rate of collet should not exceed 3mm/min. In the experiment, if whorl core club damages, experiment become invalid. The hardness of whorl core club should ≥ 45HRC. Its whorl public errand is 5h6g, but it is via should be being controlled greatly inside the 1/4 range that belt of 6g public errand approachs lower limit. 4.

Strength of 2 heads union twists riveting nut whorl core club (see a picture 2) , apply to load to till rupture,carry on his shoulder or back, rupture should not happen in head and columnar part to have sex place; Its load value should accord with a watch the regulation of 1. When having a test, the floating rate of collet should not exceed 3mm/min. In the experiment, if whorl core club damages, experiment become invalid. The hardness of whorl core club should ≥ 45HRC. Its whorl public errand is 5h6g, but it is via should be being controlled greatly inside the 1/4 range that belt of 6g public errand approachs lower limit. 4.

3 shear strength install riveting nut riveting in riveting board on (see a picture 3) , apply to load to till riveting nut is destroyed,carry on his shoulder or back, its shearing force should accord with a watch the regulation of 1. When having a test, the floating rate of collet should not exceed 3mm/min. 4.

4 destroy torque to install riveting nut riveting in riveting board on, falling without any lubricant conditions, twist experiment bolt (see a picture 4) . Bring to bear on torque till riveting nut ruptures or whorl is taken off buckle. Its torque value should accord with a watch the regulation of 2. The torsional experiment machine that uses in the experiment or tool, 2% what its torque measures an error to should not be more than the biggest rated torque.

Riveting is installed board the regulation of the H of ply of the biggest riveting that ply and aperture recommend by product standard and D0 or S0. Its hardness should ≥ 45HRC. Experiment bolt uses GB/T5782, 8.

The 6 horn bolt of 8 class. 4.

5 rotational torque install riveting nut riveting in riveting board on, falling without any lubricant conditions, twist experiment bolt (5) seeing a picture.

Bring to bear on torque till riveting nut and riveting board between generation is relatively rotational.

Its torque value should accord with a watch the regulation of 3.

The torsional experiment machine that uses in the experiment or tool, its torque measures an error to should not be more than the biggest spends what H reachs D0 regulation.

Its hardness should ≥ 45HRC. Experiment bolt uses GB/T5782, 8.

The bolt of 6 horn head of 8 class.
