Prevention method for rivet head deviation or rivet rod deviation
1. Rivet gun and rivet rod shall be on the same axis
2. At the beginning of riveting, the damper shall be gradually increased from small
3. When drilling or reaming, the cutter shall be perpendicular to the plate surface. Replace the rivet when the eccentricity is greater than or equal to 0.1d
Prevention method for combination of rivet head around and plate surface:
1. Check the hole diameter before riveting
2. Remove the burrs and oxide skin of the nail rod before threading
3. Stop riveting when the compressed air pressure is insufficient
Prevention method for partial failure of rivet head to combine with plate surface:
1. The rivet gun shall be vertical
Determine the rivet rod length correctly
Prevention methods for gaps between the joint surfaces of plates:
1. Before riveting, check whether the plate fits the hole diameter
2. Tighten the nut and remove the bolt after riveting
Prevention methods for rivet forming protruding head and cutting sheet metal:
1. The rivet is perpendicular to the panel during riveting
2. Calculate rivet length
3. Replace the cover mold
Prevention method of rivet rod bending in rivet hole:
1. Select rivets with proper diameter
2. The damper shall be small when starting riveting
Precautions for cracks in rivet heads:
1. Check the rivet material and test the plasticity of the rivet
2. Control the heating temperature
Prevention method for excessive cap edge around rivet head:
1. Correct selection of rivet length
2. Replace the cover mold; Reduce the number of hits
Prevention methods for too small rivet head and insufficient height:
1. Extension pin rod
2. Replace the cover mold
Precautions for scars on rivet heads:
Hold the rivet machine tightly during riveting to prevent excessive runout.
