Title: Calking apparatus
Inventor: TANAKA CHIKASHI
IPC: B23P19/04
Filed: 2001-11-20
Abstract: PROBLEM TO BE SOLVED: To realize making chips smaller though relatively larger chips are produced because a calking protrusion slides on the surface of a work if an edge-shaped calking protrusion formed at the tip of a punch is brought into line contact with the surface of a work and also the surface of the work is inclined or rugged when a steel ball for blocking the end part of a hole comprising a hydraulic circuit or the like is calked and fixed. SOLUTION: Because the calking protrusion 26 protruded at the tip of the punch 20 is formed into an approximately conical shape and the top part 27 of the tip is made into a curved-surface shape, so the calking protrusion 26 is brought into point contact with the surface 3 of the work when the punch 20 is struck in. Then, the size of the chips is made as smaller as possible even if the calking protrusion 26 is slipped due to the inclination of the surface 3 of the work or the presence of ruggedness.
