Abstract

PURPOSE: To accurately position slide cams and work the work with good accuracy by sliding the slide cams which are respectively provided with tools for working separate sections of the work directly on die surfaces.
CONSTITUTION: When a male die 11 is lowered, the 1st slide cam 28 descends, and its sliding surface 29 abuts on the sliding surface 23 of a drive cam 13, by which the 1st slide cam 28 is driven to move by overcoming the force of a compression spring 32, so that the 2nd surface 16 of the work W is pierced by a punch 31 in cooperation with a button die 20. Thence, after abutting of the 1st slide cam 28 and the drive cam 13, the sliding surface 30 of the 1st slide cam 28 abouts on the sliding surface 26 of the 2nd slide cam 24. Thereupon, the 2nd slide cam 24 is driven by being pressed by the 1st slide cam 28, and linearly moves on a lower die 12 by overcoming the force of a spring 27, so that the 1st surface 15 of the work W is pierced by a punch 25 in cooperation with a button die 19.
