Abstract: This invention relates to an apparatus suitable for conveying shaped blanks. This apparatus includes a pair of screw shafts extending in a direction of conveying the blank. Members for holding attracters threadably coupled to these screw shafts are movable along guide shafts. Respectively provided at the ends of the guide shafts on one side are connecting members. Screw shafts threadably coupled to these connecting members drives the attracter holding members to approach or separate from each other on a line connecting the two guide shafts. Pinions provided near the opposite ends of the guide shafts rotatably move on racks, whereby the attracter holding members are synchronously moved in parallel to each other.

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 ma
