Upsetting Presses TRIZ Cases

Selective hot forging and hot stretching form variable cross-sections near final size, cutting alloy waste and machining cost.

Annular bosses formed by a swaging tool lock tubes into connector grooves, avoiding glue or set-screws while improving joint stability and leak resistance.

Axial compression with inner support and a moving mold clearance creates consistent local wall thickening in hollow bodies without losing cross-sectional shape.

A piston-driven jaw and compressed spring simplify axial swaging by removing bearings and pins, reducing wear, tolerance buildup, and maintenance.

Axial compression plasticizes a hollow body wall so material flows into an outer expansion space, enabling selective thickening without changing cavity shape.

Forging a recessed hole and radial draw from one shaft blank cuts weight and machining time while improving steering torque transmission reliability.

A forged one-piece steering shaft extends a deep axial hole to cut weight, avoid fitting defects, and maintain reliable torque transmission.

Inclined dies convert vertical press motion into single-cycle swaging, cutting hot forging waste, energy use, and die wear.

Axial compression and a supporting inner body thicken selected hollow wall sections uniformly while preserving cavity shape and rigidity.

Support bodies prevent wall buckling in thin-walled preforms during lateral extrusion, enabling larger structures with increased wall thickness.

Cam-based mechanical compression thickens hollow member walls, eliminating heating cycles and preserving material properties.

Independent die holding means move half dies outside the press working space for rapid cooling and lubrication.
