A draw press die assembly includes an upper die, a lower die positioned beneath the upper die, a blankholder for supporting an associated workpiece, and a blankholder drive mechanism connected with at least one of the upper die and the blankholder. The blankholder drive mechanism is configured to provide a pulsating movement of the blankholder with respect to the upper die.

A hold device is attached to press tooling. The hold device includes a distance member attached to a holder, and a moving device attached to a first die unit. The holder is provided in a movable manner with respect to a punch in a press direction, and a pad is provided in a movable manner with respect to a die in the press direction. The distance member is pivotable between a home position in which the distance member does not come into contact with the second die and a preventive position in which the distance between the pad and the holder in the press direction is prevented from being equal to or less than a predetermined distance. As the holder moves relative to the punch in the first direction, the moving device causes the distance member to pivot from the home position toward the preventive position.

A deep-drawing tool for deep drawing blanks which are punched out of sheet material that is painted or coated with film material, in order to obtain flangeless molded blanks, includes a drawing bell, a drawing core, a blank holder, a force transmission device, a drawing cushion for applying a spring force to the blank holder by the force transmission device, and a drive which, after the drawing bell reaches a predetermined position in downward movement thereof, drives the force transmission device to perform a movement which precedes movement of the drawing bell.

A can body maker includes a ram shaft extending in a front-rear direction, a punch disposed at a front end portion of the ram shaft, a reciprocating linear motion mechanism connected to a rear end portion of the ram shaft to reciprocate and linearly move the ram shaft in the front-rear direction, a die having a through hole into which the punch is inserted, a cup holding mechanism which presses a cup-shaped body against an end face in which the through hole of the die opens, and a cup holder drive mechanism that oscillates the cup holding mechanism in the front-rear direction, wherein the cup holder drive mechanism has a cam structure and is disposed directly below the cup holding mechanism.

A press tooling includes a distance member pivotably supported by a holder; and a moving device provided on a first die unit. The holder is provided in a movable manner with respect to a punch in a press direction, and a pad is provided in a movable manner with respect to a die in the press direction.

A method or apparatus to produce an L-shaped pressed component includes, where a portion of a blank, having tensile strength of 1180 MPa or more, is held in a state of being clamped by a blank holder and a die, and a portion of the blank, to be formed into a top plate is held in a state of being clamped by a pad and a punch; the second step where a vertical wall, a concave ridge and a flange on the inner side of a curved portion are formed by, bend forming with a bending die, forming one, two or more material inflow promoting portion; and the third step where the die is moved in a direction toward a side where the blank holder is disposed to form a vertical wall, a concave ridge, and a flange on the outer side of the curved portion by draw forming.
