TL;DR: In this article, various rollers are carried on a single mount to hem a flange in a single pass, including induction heating and air quenching, and friction from a rotatably driven roller to reduce bending stresses during hemming.

TL;DR: Work hardenable aluminum alloy sheet material is progressively stamped to a final stamped shape in a succession of stamping operations as mentioned in this paper, where a blank sheet of annealed starting material is stamped into a least a first preform shape between heated stamping tools to form a pre-form shape and subsequently anneal the worked preform shapes.

TL;DR: In this article, an insulating liner for use in an exhaust port of an internal combustion engine or the like consisting of a formed thin wall tubular body of rigidized fibrous ceramic such as fibrous alumina-silica material (Fiberfrax) with an abrasion resistant ceramic coating fused onto the inner gas-exposed surface of the body.

TL;DR: In this article, a binder ring assembly includes an upper ring that is heated so as to prevent the cooling of the preheated blank, and a lower ring that supports the upper ring and is fixedly connected to the lower ring by spaced apart connectors so that the heat transfer path from the heated upper ring to lower ring is minimized.

TL;DR: In this paper, a self-contained die cushion assembly for use in a stretch-forming process involving heated tooling is presented, where a lower plate is mounted below an upper plate that undergoes different thermal expansion than the lower plate.
