A magnesium alloy thick and thin tube butting mechanism is disclosed in the utility model and includes a tube butting mold, a tube butting mandrel, and a hydraulic actuator. The tube butting mold has a mold heating component used for magnesium alloy tube to enter a tube wire drawing mold. A material is heated. The magnesium alloy thick and thin tube butting mechanism may further include a tube heating component configured to pre-heat the magnesium alloy tube before the magnesium alloy tube enters a tube mold.

A method of incrementally forming workpiece is provided by the present disclosure. In one form, the method includes securing a sacrificial material layer to at least one surface of the workpiece, imparting a force directly to the sacrificial material layer with at least one forming tool, and incrementally forming the workpiece to a desired geometry based on a tool path of the forming tool.

A machining surface of a die are provided with a pair of inclined surfaces facing each other across a gap and a flat surface interposed therebetween. Each inclined surface includes an inner end portion on a side near the flat surface and an outer end portion on a side farther away from the flat surface. The molding method includes a mounting step of mounting the metal sheet on the die to span both inclined surfaces, and a pressing step of forming a reduced-thickness portion by pressing the metal sheet between the punch and the inclined surfaces of the die. The pressing step includes setting a bottom dead center of the punch to maintain a gap formed between the inner end portion and a surface of the metal sheet facing the inner end portion.

A tool for use during double sided incremental forming of a workpiece. The tool includes a sleeve with a hollow interior space. A contact member is positioned within the hollow interior space of the sleeve. The contact member is sized with a working tip positioned outward beyond the sleeve to contact against a workpiece. A mount is positioned on the opposing end of the sleeve and configured to connect to a tool holder. The tool is configured to provide for translational and/or rotational movement of the contact member. The axial and rotational movement provides for the working tip to remain in contact with the workpiece during the forming process.

A high-strength metal plate for vehicles is provided. The plate includes oval embossments that protrude from the plate. The embossments include first embossments that have a longer axis oriented in a first direction and second embossments that have a longer axis in a second direction. Bridges are provided on portions of the flat plate between the embossments and flat portions are provided on the flat plate to be surrounded by the first and second embossments while the bridges separate the flat portions from each other.

An automotive component manufacturing method includes a molding process of pressing a portion of a hollow tube formed from a metal material, or a composite material including a metal and a resin, so as to deform the portion of the hollow tube, from a tube outer side toward a tube inner side, to beyond an axial center of the hollow tube, and mold the portion of the hollow tube into a deformed section deformed with a concave profile; and a deformation process of deforming a location having a high level of residual stress in a closed cross-section configured by the deformed section so as to deform the location out-of-plane.

A method is presented. A tool path having planar parallel alternating paths connected by a plurality of curved transitions is generated. A forming tool is driven along the planar parallel alternating paths and the plurality of curved transitions to shape a material into a workpiece.

A system includes a frame configured to hold a workpiece and first and second tool positioning assemblies configured to be opposed to each other on opposite sides of the workpiece. The first and second tool positioning assemblies each include a toolholder configured to secure a tool to the tool positioning assembly, a first axis assembly, a second axis assembly, and a third axis assembly. The first, second, and third axis assemblies are each configured to articulate the toolholder along a respective axis. Each axis assembly includes first and second guides extending generally parallel to the corresponding axis and disposed on opposing sides of the toolholder with respect to the corresponding axis. Each axis assembly includes first and second carriages articulable along the first and second guides of the axis assembly, respectively, in the direction of the corresponding axis.

An apparatus and method for treatment of articles, using glass failure generated pulses. The apparatus and method is directed towards the hardening and compaction of a spherical article surrounded by a glass orb in a confined arrangement. The apparatus includes a striker having first and second opposing strikers for striking the glass orb from different sides of the confinement arrangement, to create an explosive reaction that pressure-treats the spherical article, thereby causing the hardening and compaction.
