The caulking machine has a column (21) having a table (38) for placing a work having rivet shanks passing therethrough, a cylinder (23) vertically movably mounted on the column (21), a piston shaft (24) fixedly mounted in the cylinder (23) so as to be movable together with the cylinder (23), a spindle (25) rotatably mounted in the piston shaft (24), and a rivet head forming tool (26) having a forming shaft (27) and secured to the bottom end of the spindle (25). The forming shaft (27) is adapted to be pressed against the rivet shank on the work by stretching the cylinder (23) and rotated by a motor (28) through the spindle (25) to form a rivet head on the rivet shank. The machine has a rotation detector (31) for judging whether a rivet head is being formed or the machine is idling by measuring the rotation of the forming shaft (27). If judged that the machine is idling, a display device can be activated and the operation of the machine can be stopped. <IMAGE> |
