PURPOSE:To perform the change of a finger without manual aid and to improve the operation rate of a press by fixing a finger to a fitting member, fitting the fitting member to a feedback and providing the holder holding the fitting member by receiving it from a feeding car integrally with a lower die. CONSTITUTION:The feeding bar 4 is moved in the opening direction individually and descended. As a result a fitting part 6 is engaged with a holder 29 and when the fixture by a clamping mechanism is released in that state, a finger 5 is delivered to the holder 29 together with the fitting part 6 and held on the holder 29. The finger 5 is thus removed from the feeding bar 4, integrated with the lower die 1 to to be changed as well and removed from a press machine by moving an upper die and lower die to the external part from the press machine. With the operation opposite to this a new finger 5 is fitted. |
