U-O forming of a component curved about three spatial axes
The present disclosure relates to a method for producing a shaped sheet metal component from a billet by means of U O forming, wherein firstly a preform is created by the U-forming and then a final shaping is performed by the O forming to give a final form.
PANEL-SHAPED FORMED PRODUCT AND METHOD FOR PRODUCING PANEL-SHAPED FORMED PRODUCT
A panel-shaped formed product made of a metal sheet includes a top panel portion, an opening portion, and a vertical wall portion. The top panel portion is polygonal. The opening portion is provided in the top panel portion. The vertical wall portion extends from at least not less than two adjacent borders among the borders of the top panel portion. At least one pair of each vertical wall portion of pairs of adjacent vertical wall portions of the vertical wall portions has a stepped portion. As a result, the panel shaped formed product has fewer defects such as cracks and wrinkles even when it has a shape that is difficult to form.
CAN END WITH A COINED RIVET, TOOLING ASSEMBLY THEREFOR AND A METHOD OF FORMING
A can end including a central panel and a coined rivet disposed on the central panel. A press, a station, and/or a tooling assembly structured to form a coined rivet as well as a method to form the coined rivet is also provided.

Press formed product, automobile structural member with the press formed product, and method for producing press formed product
Disclosed is a press formed product which is formed from a single steel sheet. The press formed product includes two vertical wall portions, a top plate portion which connects two vertical wall portions with each other, and a projecting portion which projects from at least one boundary portion of two boundary portions each of which connects the vertical wall portion and the top plate portion with each other. In the projecting portion, a steel sheet extending from the vertical wall portion and a steel sheet extending from the top plate portion project from the boundary portion so as to overlap at an overlapping portion located at least at a distal end of the projecting portion. The projecting portion is present at least at a portion of the press formed product in a longitudinal direction. An angle formed between the top plate portion and the overlapping portion is larger than 180°.
STAMPING APPARATUS HAVING A PART-TIME DRAW BEAD
A stamping apparatus that includes an upper die, a blank-holding binder, and fixed lower die. The fixed lower die features a drawing punch and the upper die features a corresponding cavity. The fixed lower die includes a stake bead and a corresponding depression is present on the upper die. The blank-holding binder includes a draw bead and a corresponding depression is present on the upper die. In the stamping process, the draw bead engages a blank in a first stage, causing the blank to begin to stretch into the shape of the drawing punch with a greater tightened partially finished panel shape. In a second stage, the draw bead disengages the blank as the blank is drawn towards the drawing punch. In a final stage, the stake bead engages the blank to tighten the blank around the drawing punch into a final shape.

Pressed component manufacturing method and press apparatus
A method for manufacturing a pressed component including an elongated top plate, a wall having one end connected to a short direction end portion of the top plate, that curves with a convex shape bowing toward an opposite side to the top plate as viewed from an upper side of the top plate, and that includes a sharp curve portion, and a flange that is connected to another end of the wall, and that extends in a plate thickness direction of the wall toward the opposite side to the top plate side. The manufacturing method includes pressing to form an intermediate formed component including a preliminary flange and pressing to deform the preliminary flange to form the preliminary flange into the flange.

Die stacker
A die stacker for stacking stamping dies has a supporting base, an attachment stem projecting upwardly from said base for insertion into the slot of a slotted foot of a die, and a clamp moveably mounted on said stem which can be moved into or out of clamping engagement with a slotted die foot. Several such die stackers are attached to a die to support the die in a stack or on the floor with the die spaced above the floor.
