Abstract
The transfer press has a blank-supply mechanism for supplying blanks which are materials for every kind of part to be manufactured by pressing, one by one to a press, a blank-transport mechanism for carrying blanks from the blank-supply mechanism to the press, a transfer feed mechanism for feeding blanks that have been supplied to the press one by one to dies of each stage along the bed of the press, a die exchange mechanism for exchanging dies when different parts are to be manufactured, a feed bar exchange mechanism for removing and exchanging feed bars which are a part of the transfer feed mechanism, when dies are to be changed, a die cooling oil circuit connecting mechanism for connecting a cooling circuit to a newly placed die in order to cool it, a pressure adjusting mechanism for die cushioning mounted on the bed of the press, and a program control mechanism for the automatic operation of the press, which controls the above-described mechanisms as well as the press in relation to blank supplying and manufacturing conditions.
