PROBLEM TO BE SOLVED: To obtain a turret punch press equipped with a die elevation means, which can be used for a die auto index station. SOLUTION: In a turret punch press having die index stations on the upper part and the bottom part turret 15, a die holder 35 is installed on a bottom turret die index station so as to freely revolve indexing. While an ejector pipe 37 having a flange 41 in its head part is installed freely elevatably in the die holder, it is integrally installed with the die holder in revolving freely. A pressure receive spacer 45, which holds the die 43 on the head flange part and receives a load during a punching processing on the bottom of the head flange, is installed freely detachably. The die upper face is installed between a pass line position PL and a pass line bottom position freely elevatably by attaching/ detaching the pressure receiving spacer 45.
