Claims

[Claims for Utility Model Registration] A device for caulking a part having a cylindrical protrusion longer than the wall thickness of the object to be attached to the periphery of a through hole formed in the object to be attached, the device relatively approaching and separating. an upper die holding member and a lower die holding member which are respectively provided on the upper die holding member and the lower die holding member and each having opposing annular pressing surfaces for pressing the periphery of the through hole; A mold punch and a lower mold punch, and a same-sized molding punch that can freely move relative to the upper mold punch in a pressing force direction and protrudes from the upper mold punch and opens inside the annular pressing surface of the upper mold punch. an inner punch having a tip that can be fitted into the cylindrical projection and a tapered portion that becomes larger in diameter as it approaches the upper die punch following the tip; and the upper die holding member. and a lower mold holding member are brought close together and the inner punch is fitted into the cylindrical projection, a preload in the direction of a pressing force that allows the tapered portion of the inner punch to expand the tip of the cylindrical projection. an elastic member that applies a force to the inner punch and allows the inner punch to move into the upper punch when a reaction force exceeding the preload is applied to the inner punch; By one relative approach action with the mold holding member, the tip of the cylindrical protrusion protruding from the through hole is expanded and simultaneously pressed against the periphery of the through hole, thereby caulking the part to the object to be attached at once. A caulking device characterized by:
