Method and apparatus for producing pressed component
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.
PRESS TOOLING
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. 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.

HOLD DEVICE
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.

Deep Drawing Tool and Deep Drawing Process for Deep Drawing Blanks
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.

Cylinder holder for a hydroforming device, and hydroforming device
A cylinder holder for a hydroforming device has a substantially cuboid cylinder holder body with a hydraulic cylinder seat to which a hydraulic cylinder can be fixed. The hydraulic cylinder is configured to supply a hydroforming fluid to a workpiece to be shaped. The cylinder holder further includes a base plate to which the cylinder holder body is fixed at a predetermined angle with an anti-rotation lock unit.

Press apparatus
Provided is a press apparatus which ensures high production efficiency and has less chances of breakdown. Specifically, the press apparatus has a base placed on a floor, and a platform arranged over the base to face the base and move up and down. A lower die, on which a steel plate is to be placed, is fixed to the base. An upper die is fixed to the platform to press the plate against the lower die and turn it into an initially formed product through a downward movement of the platform, and to pressure-hold the initially formed product with the lower die. A machining die is supported on the platform to move up and down to machine the initially formed product and form a final product by moving down while pressure-holding the initially formed product.
