<P>PROBLEM TO BE SOLVED: To easily work an air flow passage, when providing the air flow passage for discharging a punched piece in a die tool, and to generate an air flow effective for separating the punched piece from a punch in an inside of a discharge hole of the die tool. <P>SOLUTION: The die tool 1 includes a die hole 2 along a punching-directional one axis O1, and the discharge hole 3 communicated with the die hole 2 therealong, the die tool 1 includes an air flow-in port 4a opened on an outer face 1a of the die tool 1, and the air flow passage 4 communicated with the discharge hole 3 from the air flow-in port 4a, and the air flow passage 4 is extended along an axis P1 (P2, P3) inclined with respect to a reference line L1 (L2, L3) passing the center of the air flow-in port 4a and the one axis O1, in view from a punching-directional upper side. <P>COPYRIGHT: (C)2013,JPO&INPIT |
