<p>A punching press comprising a die magazine disposed above a machining table supporting a work in parallel to a main frame supporting a machining head and a die carrying device for transferring a die between the die magazine and the machining head. A die mounting method comprising an insertion step in which a die carrying means is inserted horizontally relative to die mounting portions in a state in which minute gaps are formed between respective abutment surfaces of upper and lower dies relative to the die mounting portions and respective pressure receiving surfaces of the die mounting portions that confront those respective abutment surfaces, a lowering step in which after the insertion step is completed, the die carrying means is lowered in a direction in which a minute gap is eliminated which is formed between the abutment surface of the lower die and the pressure receiving surface of a die mounting portion which confronts the abutment surface of the lower die, and a withdrawing step in which after the lowering step is completed, the upper and lower dies are held at the die mounting portions and then the die carrying means is withdrawn in a horizontal direction.</p> |
