  • Patent number: 8573020
    Abstract: Can shells are produced with tooling installed on a 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 pistons. An air chamber is connected by air spring passages to the inner pressure sleeve piston, and the outer pressure sleeve receives the same air as the air chamber or lower pressure air. The die center punch has an insert which initiates the drawing of a cup, and the inner pressure sleeve and die center punch have contoured surfaces which mate with opposing surfaces on a die core ring to form and clamp the chuckwall of the shell during downstroke of the press. A panel punch has peripheral surfaces which form the panel wall and countersink of the shell during upstroke of the press.

  • Publication number: 20130263637
    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.

  • Publication number: 20130228001
    Abstract: A method for forming an undercut portion of a formed article formed by plastically deforming a plate-shaped workpiece and a method for manufacturing a formed article having an undercut portion are provided. In these methods, the undercut portion is formed by press working performed using a punch and a die. These methods make the forming work more economical and more efficient. An outer portion of a plate member 91 (plate-shaped workpiece) located outward of a portion where an inwardly inclined portion 94 (undercut portion) is to be formed is bent by an angle determined such that an undercut surface 94a which constitutes the inwardly inclined portion 94 becomes parallel to the pressing direction of a punch 110. In addition, a peripheral wall portion 93 inclined by an angle corresponding to the bending angle is formed on the outer portion.

  • Patent number: 8522593
    Abstract: A method for producing highly dimensionally accurate, deep-drawn half shells with a base region, a body region and a flange region, includes firstly forming a pre-formed half shell from a blank and then shaping the pre-formed half shell into a finally formed half shell, wherein the pre-formed half shell has excess blank material due to its geometric shape and wherein, owing to the excess material during the shaping of the pre-formed half shell into its final shape the half shell is compressed into the finally formed half shell by at least one further pressing process. The method requires that the pre-formed half shell has excess blank material in a transition region between the body region and flange region.

  • Patent number: 8511125
    Abstract: Beverage can manufacturing apparatus is provided in the form of a set of N necking stations S1, S2 . . . SN for progressively necking a beverage can body having a diameter greater than or equal to 2.8 inches to result in an open end designed to receive a first standard end. The necking stations are constructed such that a subset of the necking stations Si . . . Sj, where 1?i<j<N, progressively neck the beverage can body to result in an open end designed to receive a second standard end for the beverage can. The diameter of the first standard end is less than the diameter of the second standard end. For example, the first standard end is say a 202 standard end and the second standard end is a 209, 204, or a 206 standard end. Alternatively, for example, the first standard end could be a 206 end and the second standard end could be a 209 standard end.

  • Patent number: 8511129
    Abstract: A press forming method for a metal sheet uses dies, a surface roughness of which is an arithmetical mean roughness Ra of 7.5 ?m or smaller, which are used as a punch, an upper die, and a blank holder. Fluid with a kinematic viscosity of 500 mm2/s or lower is supplied to a space between a metal sheet and the blank holder, a space between the metal sheet and the punch, and a space between the metal sheet and the upper die. A die is detached from a workpiece in the middle of forming, and resuming the forming.

  • Patent number: 8511134
    Abstract: Forming processes such as hot creep forming or superplastic deformation require a die former. This die former includes a lower die and an upper die within which an initial roughly shaped component is placed and then shaped by downward pressure between the die parts. Previous arrangements have included a simple stop to engage edges of the component to define position. In use, due to the nature of the forming process, movement of the component can occur, and in such circumstances it may be necessary for the operator to adjust the position of the component during the forming process. By utilising pegs about the periphery at least of leading and trailing edges of a component, a better edge definition is created, thereby reducing the requirement for interim positioning of the component in use.

  • Publication number: 20130205854
    Abstract: An elevated temperature forming system in which a sheet metal workpiece is provided in a first stage position of a multi-stage pre-heater, is heated to a first stage temperature lower than a desired pre-heat temperature, is moved to a final stage position where it is heated to a desired final stage temperature, is transferred to a forming press, and is formed by the forming press. The preheater includes upper and lower platens that transfer heat into workpieces disposed between the platens. A shim spaces the upper platen from the lower platen by a distance greater than a thickness of the workpieces to be heated by the platens and less than a distance at which the upper platen would require an undesirably high input of energy to effectively heat the workpiece without being pressed into contact with the workpiece.

  • Patent number: 8468866
    Abstract: In the die cushion device, a shock absorber device relieves shock between a cushion pad and a support section. The shock absorber device includes a damping section and an elastic section. The damping section generates reaction force in accordance with the relative speed of the cushion pad with respect to the support section. The elastic section generates reaction force in accordance with the relative displacement of the cushion pad with respect to the support section. The controller section controls a servomotor so that a speed difference between the speed of the slide member and the speed of the support section is set to be a predetermined target speed difference value that changes over time.
