Patent JP-H044938-A (JP)
Title: Method for riveting holder
Inventor: MURAKAMI HIDEJI
IPC: B21J15/14
Filed: 1990-04-19
Abstract: PURPOSE:To prevent the diameter of a rivet hole from expanding and to improve the accuracy of a holder by providing a cavity in the center of the tip of a punch and making the pressed part of a rivet axis out of a peripheral part only separated from the center. CONSTITUTION:When the axis of the rivet R got out of the holder H is calked and expanded, the calked part is only a peripheral part far from the center of the rivet axis 2 and so the expanding force of the rivet axis 2 becomes very weak at a place where the rivet is inserted into the rivet hole 3. When the rivet axis is calked totally, the axial material falls in the central part of the rivet axis and moves in an expanding direction at a place where the rivet is inserted into the rivet hole. When only the peripheral part is calked, the calking force escapes at the part got out of the rivet hole in the shape of expanding force to the peripheral direction, therefore, the calking force does not act as expanding action at a place where the rivet is inserted into the rivet hole. In this way, the diameter of the rivet hole and that of the holder can be prevented from being expanded and the accuracy of the holder can be improved.
