THE EFFECT OF RIVET GUN OPERATING PRESSURE AND HOLE CLEARANCE ON RIVET SHEAR STRENGTH IN SHEET METAL RIVETING PROCESS

Abstract

Several parameters related to the riveting process and the quality or result of the rivets are squeeze force, rivet length, rivet diameter, and hole clearance. This riveting experiment uses a semi-automatic riveting tool to set riveting parameters. The parameter set is the operating pressure of the rivet gun with a semi-automatic riveting tool, while the drilling process on sheet metal makes the hole clearance. The results of riveting using an automatic rivet tool show that the operating pressure of the rivet gun and the hole clearance have a direct effect on the shear strength of the rivets; the higher the operating pressure of the rivet gun and the greater the hole clearance will increase the shear strength of the rivets. This rise in the rivet’s shear strength is because, during the riveting process, the rivets experience strain hardening when pounded using a rivet gun.
