Usually the ability of the rivet gun to rive is limited by the material, size and type of the rivet. If the button head blind rivet of the button head is selected, the rivet gun with a slightly larger pulling force should be selected. This is determined by the structural principle of the rivet. The shear strength of the button head blind rivet is obtained by adding the shear strength of the shank and the sleeve, along the shear line between the connectors.
The tensile strength of the button head blind rivet is different from that of the locking bolt. The button head blind rivet forms a clamped buckle on the blind end side by tail deformation or sleeve expansion. The sleeve and portions of the shank that are permanently locked therein prevent failure of the fastener along the centerline.
During the riveting of the rivet gun, the casing is squeezed, causing it to deform outward and bulge. This swollen portion is pressed tightly against the material being joined. Once the shank is permanently locked in place, the tail will be pulled off to complete the process. Pull the tail of the shank and pull the shank head into the sleeve. The expansion of the sleeve thus forms a conforming surface that presses against the material being joined.
Note: In actual use, the pre-tightening force of the button head blind rivet will vary depending on the application condition of the rivet gun tension. Install the hole into the drill, the rivet gun is placed on the tail of the fastener; start the rivet gun, the blind end of the fastener begins to deform; the joint is locked, the inner lock ring is formed; the tail of the nail is disconnected and the installation is completed.www.yukerivet.com
