Control and prevention of defects in conventional spin riveting technology

1. Check the positioning and support of the parts on the fixture, the design of the rivet head, the size, material and hardness of the rivet, and the applicability of the rivet structure to the riveting process; the structure of the rivet and the structure of the riveting fixture must ensure that the area of u200bu200bthe supporting surface is at least greater than 1.2 times the area of u200bu200bthe riveting surface, and the maximum gap between the rivet and the riveting seat should be controlled within 0.3mm.

2. At the beginning of the riveting process, adjust the position of the riveting bed and lock it; measure the riveting height of the first and final parts, standardize the operation of the riveter, and stay for a few seconds after the riveting head falls to the lower limit position Release the pedal again.

3. Check the operation of the operator, the positioning of the riveting fixture, the riveting height and the manufacturability of the rivet structure.

4. Check and standardize the operation of the operator and the positioning of the parts on the fixture; in this case, try to increase the pre-compression mechanism on the fixture.

5. Check the operation of the operator, the positioning of the riveting fixture, the riveting height and the manufacturability of the rivet structure, and the material composition and hardness of the rivet and parts.

6. Check the structure design of the rivet head and notify the tooling designer to change it.
