发明名称 MECHANISM FOR ELEVATING/LOWERING DIE OF TURRET PUNCH
摘要 <p>PROBLEM TO BE SOLVED: To facilitate elevating/lowering of a die for forming without hindering at the time of feeding a work by arranging only one die elevating/lowering means to a turret. SOLUTION: Each die 5 for forming arranged in the lower turret 2 is made to be possible to elevate/lower. The die elevating/ lowering means 16 for elevating/lowering the die 5 from the lower part of the lower turret 2 is arranged at one position of a rotating locus L of the die 5 accompanied with the rotation of the lower turret 2, e.g. the position acted to a punching P. In each die 5, a projecting part 29a projected from the lower surface of the lower turret 2 is arranged. The die elevating/lowering means 16 is constituted with an advancing/retreating member 17 having an inclining surface part 17a, on which the projecting part 29a can run, and a horizontal surface part 17b and possible to advance/retreat in the horizontal direction and an actuator 18 for advancing/retreating.</p>
