Abstract: A press forming method for suppressing wall camber of a side wall portion due to springback of a press-formed product including a top portion, the side wall portion and a flange portion includes: a first forming step of press-forming a preformed part including a flange portion having height continuously changed in an axial direction to have a concave shape, a convex shape or a concavo-convex shape more largely than a target shape of the press-formed product in a height direction to provide a height difference; and a second forming step of press-forming the preformed part into the press-formed product having the target shape to reduce the height difference of the flange portion of the preformed part.

Abstract: Provided is a press-forming method including three steps for preventing spring-back in a hat-shaped cross section shape of a final formed article. In the first step, from a blank, a preformed article in a first form is obtained, the preformed article including a top surface, left and right vertical walls, and left and right tapered portions extending outward from lower ends of the left and right vertical walls, respectively, of a final formed article having a hat-shaped cross section. In the second step, the compression can be applied to the entirety of the top surface, the left and right vertical walls, and the left and right flanges of the final formed article having the hat-shaped cross section, whereby the spring-back can be sufficiently prevented. In the third step, obtain the final formed article having the hat-shaped cross section.

Abstract: While a compression part (B1) in a bottom wall part of a cup-shaped workpiece (B) is compressed by an inner punch (11) and an inner die (14) and moved in a direction to get away from an intermediate die (15), the inner die (14) is pushed toward the inner punch (11); and a compression part (B2) being an outer end portion in a radial direction of the workpiece (B) is compressed by an outer punch (13) and an outer die (16) and moved in an direction to approach the intermediate die (15), to thereby suppress the workpiece (B) in the compression part (B2) from material-flowing in a direction to get away from a central axis (10), whereby thickness reduction processing of the compression part (B1) and thickness increase processing of a vertical wall part (B3) of the workpiece (B) sandwiched by an intermediate punch (12) and the inner die (15) and a vertical wall part (B4) of the workpiece (B) sandwiched by the intermediate punch (12) and an outer die (16) are performed.

Abstract: A can end for a two-piece beverage container has a curl positioned about a longitudinal axis which defines an outer perimeter of the can end. A circumferential wall angles downwardly and radially inwardly relative to a radially inner portion of the curl. A strengthening member extends radially inwardly relative to the circumferential wall. A center panel extends radially outwardly from the longitudinal axis towards the strengthening member and has a diameter greater than 87.7% of an overall diameter of the can end. A frangible score and a hinge portion define an openable tear panel in the center panel. A stay-on tab is attached to the center panel and has a nose portion overlying the tear panel opposite a lift end of the tab.

Abstract: A press forming method forming an extended part by extension in a later forming period after deep drawing, the deep drawing process carried out with working at 100-250° C., and the extension forming process carried out colder at less than 50° C., whereby the extended part is formed by extension in a cup shaped low parts formed by deep drawing. Thus, press forming products containing formed elements can be deep drawing formed and extension formed at a high forming rate of 10 mm/sec or greater, which can assure high productivity. By making a steel plate temperature 100-350° C. during press forming and by making the forming rate in the later forming period where extension forming is carried out slower than the forming rate in an earlier forming period where extension forming is not carried out, cracking of the extended part can be prevented and press forming limitations can be improved.

Abstract: A cylinder member of an automatic transmission that includes an outer peripheral introducing portion having a shape that is able to be formed by ironing without forming and trimming of a flange portion which was conventionally required for forming an outer peripheral introducing portion. Therefore, steps required for forming the flange portion are omitted, and the number of steps for manufacturing the cylinder member is reduced. Without using a large-scale press machine such as a progressive press and a transfer press, the cylinder member is manufactured by a smaller-sized press machine, thereby reducing equipment investment required for manufacturing the cylinder member.

Abstract: An apparatus and method of forming a metallic cup that is subsequently reformed into a container body is provided. More specifically, the present invention relates to an apparatus and methods used to form a metallic cup with a reformed bottom having an inwardly oriented projection. The inwardly oriented projection reduces a height of the metallic cup but utilizes the same amount of metallic stock material as a taller cup with substantially the same diameter that does not have an inward projection. The inwardly oriented projection thus allows the use of a conventional bodymaker and other can manufacturing tools to convert the cup into a container body of a preferred size and shape.

Abstract: Can shells are produced with tooling installed on a single action mechanical press, and the tooling includes an upper retainer supporting a blank and draw die enclosing an outer pressure sleeve and an inner pressure sleeve surrounding a die center punch, all having air actuated pistons. The die center piston has an air reservoir connected by air passages which form air springs for the inner pressure sleeve, and the outer pressure sleeve receives the same controllable air as the reservoir or low pressure plant air supply. The inner pressure sleeve has a projecting nose portion which initiates the drawing of a cup and has contoured surfaces which mate with corresponding surfaces on a die core ring to form and clamp the chuckwall of the shell during downstroke of the press. A lower panel punch forms the center panel, panel wall and countersink of the shell during upstroke of the press.
