The invention discloses a stainless steel fastening connection system. Including stainless steel short-tail rivet fasteners, special riveting tools and demolition tools, the rivet surface is covered with a lubricating coating, and the friction coefficient of the lubricating coating is less than 0.05; The top surface of the front end ring of the anvil is provided with detection protrusions at intervals; the demolition tool is composed of a demolition cutter head and a demolition claw driven by an external force, and the side of the inner ring of the demolition cutter head is provided with a blade for cutting the collar; the blade has Two-stage step structure, the back step of the blade is higher than the front step of the blade, and the front step of the blade adopts a circular arc edge structure. The system of the invention is a special combined system for fasteners, riveting and breaking; it can solve the problem of low pre-tightening force of the traditional stainless steel fastening connection system and meet the connection requirements of high-strength nodes. It effectively solves the problems of sticking material, excessive riveting force and scratches during the riveting process. |
