Abstract: A method of forming a part includes: inserting a blank into a die, the die comprising a mold mounted above a sealing counterpart; clamping the blank between the mold and the sealing counterpart; applying first pressure on the blank from the sealing counterpart so the blank is pressed upward to form a shaped part corresponding to the mold; applying a vacuum to the shaped part to hold it against the mold also after separating the mold and the sealing counterpart, the vacuum applied through at least one opening in the mold located in a corner of the mold that the blank does not reach when the first pressure is applied; and discontinuing the vacuum to allow the shaped part to be released from the mold.

Abstract: Provided is a manufacturing method for a cylindrical portion in a cylindrical shape protruding in a plate thickness direction of a plate-like portion made of metal, the cylindrical portion being formed integrally with the plate-like portion. The manufacturing method uses a manufacturing device including: a first metal mold provided with an inner circumferential surface that comes in contact with an outer circumferential surface of the cylindrical portion; a second metal mold coming in contact with a protruding tip of the cylindrical portion; and a third metal mold coming into press contact with a workpiece toward a side of the second metal mold. The third metal mold is displaced toward the side of the second metal mold and a portion of the workpiece undergoes plastic flow toward the inner circumferential surface, whereby the portion that underwent the plastic flow comes into press contact with the inner circumferential surface.

Abstract: Examples of tooling fixtures and methods for manufacturing computing devices are described. According to some examples, a computer component may be shaped using successive steps of forging after deep drawing. In some examples, certain components may be assembled to form sub-assemblies of computer components and the sub-assembly may then be machined to drive closer tolerances. According to other examples, a work holding tool is described which may include a first plurality of individually movable pins for supporting a first surface of a work piece, the tool also having a second plurality of individually movable pins for applying a restraining force over a second opposite surface of the work piece to retain the work piece in position while maintaining it in its natural state.

Abstract: In an embodiment, the method includes providing a blank, applying a marking to the blank in places and heating the blank with the marking to a deformation temperature. The method further includes deforming the blank to form the workpiece and cooling the workpiece, wherein deforming is a hot forming, wherein the marking remains at the workpiece at least until after deforming and cooling, and is not destroyed by deforming, and wherein the marking has a difference in the degree of reflection and/or a difference in the degree of reflectance and/or a difference in albedo of at least 15 percentage points in at least part of the near ultraviolet, visible and/or near infrared spectral range both with respect to the blank and with respect to the workpiece.

Abstract: The invention relates to a method for producing highly dimensionally accurate, deep-drawn half shells having a bottom region, a jacket and optionally having a flange, wherein a half shell pre-formed from a blank is formed into a finished half shell, wherein the pre-formed half shell has excess blank material on account of its geometrical shape, and the half shell being upset by way of at least one pressing operation in an upsetting tool to form the finished half shell during the forming of the pre-formed half shell into its finished shape on account of the excess blank material. The object of specifying a method and an apparatus, by way of which the process reliability can be increased during the production of a half shell, is achieved by way of the abovementioned method by virtue of the fact that the size of the upset gap is reduced during the closing of the upsetting tool to the actual wall thickness of the jacket of the pre-formed half shell. In addition, the object is achieved by way of an upsetting tool according to the invention by virtue of the fact that two side walls are provided which, together with the bottom region of the die of the second tool half, form a corresponding die, and the side walls can be displaced perpendicularly or obliquely with respect to the movement direction of the die.

Abstract: A method for producing a shaped part from an aluminum sheet that includes an aluminum alloy, in particular an aluminum alloy of the 5000 series. The method includes introducing at least one aluminum sheet in a forming tool and cold-forming the aluminum sheet in the forming tool, and heating the cold-formed aluminum sheet at least once at least in some regions and at least once further metal forming the aluminum sheet. In order to create advantageous conditions for the method, it is proposed for the heated aluminum sheet to be subjected to the further metal forming step even before a temperature has been reached which the aluminum sheet has during the cold forming thereof.
